TLP548J

TOSHIBA · Transistor, Photovoltaic Output Optoisolators · DIP-6

TLP548J from TOSHIBA, in a DIP-6. 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 (LED) passive Infrared LED anode; the input diode is rated for 50 mA forward current (derate 0.7 mA/°C above Ta 53°C) and 5 V reverse voltage.
2 CATHODE (LED) passive Infrared LED cathode; recommended LED forward current is 10 mA to 25 mA, and the trigger LED current IFT is 7 mA max at VAK = 6 V, RGK = 27 kΩ.
3 N.C. unconnected No internal connection; the datasheet gives no function for this pin.
4 CATHODE (SCR) passive Photo-thyristor cathode; on-state current IT(RMS) is 150 mA max, and the gate-to-cathode resistor RGK should be 27 kΩ (33 kΩ max) with CGK 0.01 to 0.1 µF recommended.
5 ANODE (SCR) passive Photo-thyristor anode; peak off-state/repetitive voltage VDRM is 600 V (min) with RGK = 27 kΩ, and the supply voltage is rated 240 Vac max.
6 GATE input Photo-thyristor gate, connected to cathode via RGK = 27 kΩ; peak reverse gate voltage VGM is 5 V max.
