TLP170J

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

TLP170J 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; the datasheet rates LED forward current at 50 mA max (derated 0.5 mA/°C above 25 °C) and reverse voltage at 5 V max.
2 Cathode passive LED cathode; the LED reverse voltage rating is 5 V max, and the trigger LED current is 1 mA max (IFT, ION = 90 mA).
3 Drain passive Photo-MOSFET output drain terminal; OFF-state output voltage is rated 600 V min (Peak OFF-state voltage) and ON-state current 90 mA max.
4 Drain passive Photo-MOSFET output drain terminal, the second drain pin of the 1-Form-A output; OFF-state output voltage is rated 600 V and ON-state current 90 mA max.
