TLP250

TOSHIBA · Logic Output Optoisolators · DIP-8

TLP250 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 lists this pin as N.C. in the pin configuration and gives no function for it.
2 Anode input LED anode input; the input threshold current is IF = 5 mA (max.) and the absolute maximum forward current is 20 mA.
3 Cathode input LED cathode input; the absolute maximum reverse voltage is 5 V.
4 N.C. unconnected Not connected; the datasheet lists this pin as N.C. in the pin configuration and gives no function for it.
5 GND power_in Ground reference for the output stage; a 0.1 µF bypass capacitor must be connected between pin 8 and pin 5, with total lead length not exceeding 1 cm.
6 VO (Output) output Push-pull driver output with peak output current rated at ±1.5 A (max.) per the features list, and recommended peak output current of ±0.5 A.
7 VO output Second driver output pin, labelled VO in the pin configuration and internally shown in parallel with pin 6; the datasheet gives no separate rating for it.
8 VCC power_in Positive supply for the detector and output stage; supply voltage range is 10 to 35 V, with recommended operating range 15 to 30 V.
