Product details

Active production – no obsolescence concern

The MOC8204SM is listed as Active with ROHS3 compliance.

4170Vrms isolation drives 400V loads from logic

With 4170Vrms isolation and a 400V output rating, this optoisolator bridges a low-voltage DC input (1.15V forward typical,) to a high-side transistor switching up to 100mA. The 20% minimum CTR at 10mA input means the output saturates reliably with standard LED drive current. The 5µs turn-on and turn-off times are fast enough for relay coil drivers, PLC digital inputs, and 50/60Hz phase-control circuits, but not for high-frequency PWM above a few kHz.

Industrial temperature range and surface-mount package

Rated for -40°C to 100°C, the MOC8204SM suits factory-floor cabinets, outdoor telecom shelters, and motor-drive environments. The 6-SMD gull-wing package reflows with standard lead-free profiles; the 400mV max Vce saturation keeps conduction loss low at 100mA output.

Frequently asked questions

What is the difference between MOC8204 and MOC8204SM?

The MOC8204SM is the surface-mount gull-wing version of the through-hole MOC8204. Both share the same die: 4170Vrms isolation, 400V output, transistor with base, 20% min CTR. The SM suffix indicates the 6-SMD package instead of a DIP.
