3750Vrms isolation with AC/DC input flexibility
The TLP182(GB,E: Rated for 3750Vrms isolation, this optocoupler suits applications requiring galvanic separation between high-voltage and low-voltage domains – think AC mains sensing, motor-drive feedback, or industrial PLC I/O modules. The AC/DC input type means the LED can be driven by either polarity or an AC waveform, which simplifies zero-crossing detection circuits and eliminates the need for a bridge rectifier on the primary side.
CTR margin and switching speed for BOM confidence
Current transfer ratio spans 100% min to 600% max at 5mA forward current. That wide range gives you headroom for LED degradation over temperature and lifetime – the output transistor still drives the load even if the LED dims. Typical rise/fall times of 2µs and 3µs and turn-on/turn-off times of 3µs/3µs keep switching clean for 10–100 kHz isolation applications.
Temperature range and package for harsh environments
Operating temperature from -55°C to 125°C covers industrial, automotive, and outdoor telecom enclosures. The 6-SOP package with 4 leads in a 6-SOIC footprint is a common surface-mount outline. Supplied in Tube.
