3N80 Datasheet PDF ( Pinout ) – N-Channel MOSFET Transistor

This capacitance gives rise to a current I 2 to flow through the base resistance 3n0 when a voltage ramp appears across the drain-source terminals. Brands Line Card Manufacturers. Plus, they can withstand Maximum Current A simultaneous application of high current and voltage without Figure 2. Current-Voltage undergoing destructive failure due to second breakdown.

CGD is also called the Miller capacitance because it causes the total dynamic input capacitance to become greater than the sum of the static capacitances. This continues until time t3.

CGD consists of two parts, the first is the capacitance associated with the overlap of the polysilicon gate and the silicon underneath in the JFET region. Also, BJTs suffer from thermal runaway. Figure 12 shows a typical switching time test circuit. CGS is the capacitance due to the overlap of the source and the channel regions by the polysilicon gate and is independent of applied voltage.

LS and LD are source and drain lead inductances and are around a few tens of nH. The invention of the power MOSFET was partly driven by the limitations of bipolar power junction transistors BJTs which, until recently, was the device of choice in power electronics applications. The parasitic BJT can make the device susceptible 3n8 unwanted device turn-on and premature breakdown.

We jrf gladly help you locate any Electronic or Electrical Parts. MOSFETs can also be paralleled easily because the forward voltage drop increases with increasing temperature, ensuring an even distribution of current among all components.


When a voltage ramp appears across 3n8 drain and source terminal of the device a current I1 flows through the gate resistance, RG, by means of the gate-drain capacitance, CGD.

Finally, CDS, the capacitance associated with the body-drift diode, varies inversely with the square root of the drain-source bias. They 0 are superior to the BJTs in high frequency applications where 1 10 switching power losses are important.

The leakage current flowing between source ir drain is denoted by IDSS. Figure 10 shows a typical I-V characteristics for this diode at two temperatures.

Another BJT limitation is that both electrons and holes contribute to conduction. Vth is usually measured at a drain-source current of ?

Grant and John Gower. Typical values of input Cissoutput Coss and reverse transfer Crss capacitances given in the data sheets are used by circuit designers as a starting point in determining circuit component values.

The 1-Source Electronics group of companies provides a full suite of services to the electronics manufacturing industry.

This 2 component is higher in high voltage 1 devices due to the higher resistivity or lower background carrier concentration in 0 0 5 10 15 the epi.

For drain voltages below BVDSS and with no bias on the D gate, no channel is a formed under the gate at the surface and the drain Source Source voltage is entirely Gate supported by the reverse-biased body-drift p-n junction. Channel length also affects transconductance. Figure 11 a shows the transfer characteristics and Figure 11 b is an ifr circuit model often used for the analysis of MOSFET switching performance.

Finally the lower the gate oxide thickness the higher gfs. Contact us to buy or sell excess electronic component parts and inventory. Transconductance is influenced by gate width, which increases in proportion to the active area as cell density increases.

We are a franchised distributor of electronic components, as well as a sourcing and procurement agent for hard-to-find, obsolete, and allocated parts. RG is the total gate resistance in the circuit and the voltage drop across it is given by: The lower limit of this length is set by the ability to control the double-diffusion process and is around mm today.


BVDSS is normally measured at ? Consignment and warehousing available. The limiting factor for even higher cell densities is the photolithography process control and resolution that allows contacts to be made to the source metallization in the center of the cells.

For example, a device with a gate charge of 20nC can be turned on in 20? The second part is the capacitance associated with the depletion region immediately under the gate. Their forward voltage drop decreases with increasing temperature causing diversion of current to a single device when several MOS devices are paralleled. Reduced channel length is beneficial to both gfs and on-resistance, with punch-through as a tradeoff.

CGD is a nonlinear function of voltage. It is give by Pd where: The metal oxide semiconductor field effect transistor MOSFET is based on the original field-effect transistor introduced in the 70s. Power mosfet basics IR The reach-through phenomenon occurs when the depletion region on the drift side of the body-drift p-n junction reaches the epilayer-substrate interface before avalanching takes place in the epi.

The base resistance RB must be minimized through careful design ird the doping and distance under the source region. If this b rate is exceeded then the voltage across the gate-source terminals may become higher Figure Over time, new materials, structures and processing techniques are expected to raise these limits. A large base drive current as high as one-fifth of the collector current is required to keep the device in the ON state.

Pchannel devices orf a higher VF due to the higher contact resistance between metal and p-silicon compared with n-type silicon. Good circuit design practice dictates the use of a higher gate 3n8 than the bare minimum required for switching and therefore the gate charge used in the calculations is QG corresponding to t4.
