4170Vrms isolation in a 6-SMD Gull Wing
The onsemi H11L1SVM is a single-channel optoisolator with an open collector output, rated for 4170Vrms isolation between input and output. The 6-SMD Gull Wing package suits surface-mount assembly on boards where a galvanic barrier is needed between a low-voltage logic side and a higher-voltage or noisy field side. The 1MHz data rate and 4µs max propagation delay (tpLH/tpHL) make it suitable for isolating digital signals like encoder pulses, PLC digital inputs, or serial bus lines where the timing budget can accommodate a few microseconds of latency.
Supply range and output drive
Input drive requires a forward voltage of 1.2V typical and a maximum forward current of 30mA. The 100ns typical rise and fall times keep the output edges clean for the 1MHz switching rate.
