This is one of the types of MOSFETs and is a kind of transistor.
Part Number: 4NF20L, STN4NF20L
Function: N-channel 200 V, 1 A, Power MOSFET
Package: SOT-223 Type
This is N-channel 200 V, 1.1 Ω, 1 A, Low Gate Charge STripFET II Power MOSFET.
This N-channel 200 V realized with STMicroelectronics unique STripFET process has specifically been designed to minimize input capacitance and gate charge. It is therefore suitable as primary switch in advanced high efficiency isolated DC-DC converters.
1. 100% avalanche tested
2. Low gate charge
3. Exceptional dv/dt capability
Absolute maximum ratings :
1. Gate-source voltage : VGS = ± 20 V
2. Drain current continuous (TC = 25 °C) : ID = 1 A
3. Drain current continuous (TC = 100 °C0 : ID = 0.63 A
4. Drain current pulsed : IDM = 4 A
5. Total dissipation at TC = 25 °C : PTOT = 3.3 W
6. Peak diode recovery voltage slope : dv/dt = 20 V/ns
