The 6N136TSVM is a single-channel optocoupler from onsemi that takes a DC input and drives a phototransistor with base access. Switching is fast enough for most isolated gate-drive and logic-level translation tasks — typical turn-on time is 250ns, turn-off 260ns — but not targeted at high-frequency converters running above a few hundred kilohertz.
Parametric fit for your BOM
Output voltage is rated to 20V max, and the output can sink 8mA per channel — enough to drive a downstream logic gate or a small relay coil through a transistor buffer. Current transfer ratio spans 19% to 50% at a forward current of 16mA, so the input drive needs to be sized for the minimum CTR to guarantee the output switches across temperature. The forward voltage is a typical 1.45V.
Sourcing and compliance status
The package is Bulk (tube) for the 8-SMD Gull Wing footprint.
Package and layout note
8-SMD Gull Wing package with a 0.50mm pin pitch — the same footprint as the DIP-8 surface-mount variant. The base pin on the transistor side is brought out, which lets you bias the phototransistor for faster turn-off or use it in a photodiode mode with an external amplifier.
