MOC213M

onsemi · Transistor, Photovoltaic Output Optoisolators · SOIC-8

MOC213M from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ANODE passive Anode of the GaAs infrared emitting LED (input side). Drive with forward current IF (typ 10 mA, 60 mA continuous max, VF ~1.15 V typ @ 10 mA) through an external series resistor. Reverse voltage rating VR = 6 V max.
2 CATHODE passive Cathode of the GaAs infrared emitting LED (input side). Return path for LED forward current IF; typically tied to the input-side ground or driver low-side.
3 NC unconnected No internal connection. Leave floating or tie to a convenient plane per PCB layout preference; the pin is not electrically bonded to the die.
4 NC unconnected No internal connection. Leave floating or tie to a convenient plane; the pin is not electrically bonded to the die.
5 EMITTER passive Emitter of the output-side NPN silicon phototransistor. Typically tied to the output-side ground; carries the coupled collector current (IC continuous 150 mA max).
6 COLLECTOR passive Collector of the output-side NPN silicon phototransistor. Tie to the pull-up / load through RL to VCC (BVCEO ≥ 30 V, VCE(SAT) ≤ 0.4 V at IC = 2 mA / IF = 10 mA, CTR ≥ 100 %).
7 BASE passive Base of the output-side phototransistor. Usually left open for normal photocoupling; an external base-emitter resistor RBE can be added to trade CTR for improved noise immunity and switching speed (see Figures 6-9).
8 NC unconnected No internal connection. Leave floating or tie to a convenient plane; the pin is not electrically bonded to the die.
