The 5300Vrms isolation rating covers most industrial and motor-drive isolation barriers — think PLC output modules, solid-state relay drivers, or any circuit where a microcontroller needs to switch a floating load without ground loops. Each channel delivers up to 15V at a microscopic 1µA, so this is a signal-level isolator, not a power driver; you pair it with an external MOSFET or IGBT to switch real current. ## 35µs on, 90µs off — timing for relay replacement Turn-on time is 35µs typical, turn-off 90µs typical. That is fast enough to replace a reed relay in many applications — no coil drive, no contact bounce, no arc suppression — but too slow for PWM above a few kilohertz. If you are driving a MOSFET gate through the photovoltaic output, the 90µs fall time means the gate discharge is slow; plan for a bleeder resistor or a separate gate-drive path if you need fast turn-off. ## Through-hole 8-DIP — field-swappable, no hot air needed The 8-DIP (0.300\", 7.62mm) through-hole package is a field-service favourite. You can swap it on site with a basic soldering iron and a solder sucker — no hot-air station, no reflow profile. Orientation is clear from the pin-1 notch, and the 7.62mm row spacing fits standard perfboard and sockets. If you are building a board that might need field repair, socket it. ## Active, ROHS3 — no obsolescence worry No last-time-buy notice, no end-of-life risk on the horizon.","metaTitle":"LH1262CB Optocoupler, 5300Vrms, 2-Ch Photovoltaic Output","metaDescription":"LH1262CB dual photovoltaic optocoupler with 5300Vrms isolation, 15V output, 35µs/90µs switching.
