Product details

AC/DC input opto for line-voltage sensing

The H11AA4VM is a single-channel optoisolator from onsemi that accepts both AC and DC input — the AC input capability lets it sense mains-level AC signals directly through a series resistor, saving a bridge rectifier on the primary side. Rated for 4170Vrms isolation, it bridges the safety gap between line-voltage circuits and low-voltage control logic in a 6-DIP through-hole package.

Transistor output with base access

The output is a phototransistor with a separate base terminal (6-DIP pinout), giving you the option to bias the base for faster switching or to connect a base-emitter resistor for noise immunity — handy in industrial environments where long sense wires pick up hash. Minimum current transfer ratio is 100% at 10 mA forward current, and the output can sink up to 50 mA continuous with a maximum Vce(sat) of 400 mV.

Frequently asked questions

What is the difference between H11AA4VM and H11AA1?

Both are from the H11AA family with AC/DC input and transistor output. The H11AA4VM is the standard commercial-grade version in a 6-DIP package; the H11AA1 is a higher-CTR variant (minimum 300% vs 100% at 10 mA). For most AC line-sensing applications the 100% CTR of the H11AA4VM is sufficient, but if you need more output current at lower input drive, the H11AA1 is the alternative.
