TLP351

TOSHIBA · Logic Output Optoisolators · DIP-8

TLP351 from TOSHIBA, in a DIP-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 N.C. unconnected Not connected; the datasheet gives no function for this pin.
2 Anode input LED anode; the datasheet gives Absolute Maximum forward current IF of 20 mA and a recommended ON input current IF(ON) of 7.5 to 10 mA.
3 Cathode input LED cathode; the absolute maximum reverse voltage VR is 5 V.
4 N.C. unconnected Not connected; the datasheet gives no function for this pin.
5 GND power_in Detector ground; a 0.1 µF bypass capacitor must be connected between pin 8 (VCC) and pin 5 (GND).
6 VO output Detector output; peak output current is ±0.6 A max (IOPH −0.6 A, IOPL 0.6 A) and output voltage VO is 35 V max.
7 N.C. unconnected Not connected; the datasheet gives no function for this pin.
8 VCC power_in Detector supply voltage; recommended range is 10 to 30 V, with an absolute maximum of 35 V.
