TLP176GA

TOSHIBA · Solid State Relays (MOS Output) · SOP-4-2.54mm

TLP176GA from TOSHIBA, in a SOP-4-2.54mm. 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 ANODE input LED anode terminal; the LED forward current is rated at 50 mA max and the reverse voltage at 5 V max (Absolute Maximum Ratings).
2 CATHODE passive LED cathode terminal; the LED is specified for a reverse voltage of 5 V max and a forward current of 50 mA max (Absolute Maximum Ratings).
3 DRAIN passive Photo-MOSFET output drain terminal; the off-state output terminal voltage is 400 V max and the on-state current is 120 mA max (Absolute Maximum Ratings).
4 DRAIN passive Photo-MOSFET output drain terminal (paired with pin 3); the off-state output terminal voltage is 400 V max and the on-state current is 120 mA max (Absolute Maximum Ratings).
