ZXGD3103N8TC

Diodes Incorporated · AC-DC Controllers & Regulators · SO-8

ZXGD3103N8TC from Diodes Incorporated, in a SO-8. 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 DNC unconnected Do not connect; leave this pin floating.
2 REF passive This pin is connected to VCC via resistor RREF.
3 GATEL output This pin sinks current ISINK from the synchronous MOSFET gate, with a gate driver peak sink current rating of 6 A.
4 GATEH output This pin sources current ISOURCE to the synchronous MOSFET gate, with a gate driver peak source current rating of 2.5 A.
5 Vcc power_in This is the supply pin, operating from 5 to 15 V VCC, and should be decoupled closely to ground with a ceramic capacitor.
6 GND power_in This is the ground reference point and must be connected to the synchronous MOSFET source terminal.
7 BIAS passive This pin is connected to VCC via resistor RBIAS.
8 DRAIN input Connect this pin to the synchronous MOSFET drain terminal; the continuous drain pin voltage is rated -3 to 180 V.
