Description
The 3SK74 is 20V, 25mA, N-Channel Silicon dual-gate MOSFET. A dual-gate MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of MOSFET that has two gate terminals instead of the usual one gate terminal found in standard MOSFETs. These dual-gate MOSFETs provide additional control and flexibility in electronic circuit design.
Features
1. Suitable for use as RF amplifier & Mixer in VHF TV Tuner
2. Low Crss : 0.03pF Typ.
3. High PG : 22dB Typ.
4. Low NF : 2.0dB Typ.
Absoulte Maximum ratings:
1. Drain to Source Voltage : Vdsx = 20 V
2. Gate1 to Source Voltage : Vg1s = ± 10 V
3. Gate2 to Source Voltage : Vg2s = ± 10 V
4. Drain Current : Id = 25 mA
5. Total Power Dissipation : Pt – 200 mW
