03P4J from KEXIN, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GATE | input | Gate trigger input, with gate trigger current IGT of 200 (unit as printed) at VDM=6V and RL=100Ω, gate forward current IFGM 0.1 A, gate reverse voltage VRGM 6 V, and gate power dissipation PGM 0.1 W. |
| 2 | ANODE | passive | Anode terminal, rated for repetitive peak off-state voltage VDRM 400 V and repetitive reverse voltage VRRM 400 V, with average on-state current IT(AV) 0.3 A. |
| 3 | CATHODE | passive | Cathode terminal, the reference for the gate and anode ratings, with RMS on-state current IT(RSM) 0.47 A. |
