Product details

Isolation barrier and signal rate

The 6N137M is a single-channel optocoupler from onsemi rated at 10Mbps and 5000Vrms isolation — the 5kV barrier is the deciding factor for BOMs that must meet reinforced insulation in motor drives or medical power supplies. Output is open-collector with a 50 mA sink capability; the 75 ns max propagation delay (tpLH / tpHL) keeps the part within timing budget for 10Mbps CAN or SPI isolation links.

Temperature grade and supply rail

Operating from 4.5V to 5.5V with a 1.45V typical forward voltage, the 6N137M runs off a single 5V rail on the output side — no secondary regulator needed. Rated for -40°C to 100°C, this through-hole DIP-8 version spans the full industrial enclosure temperature window, unlike the surface-mount 6N137SM sibling which stops at 85°C.

Frequently asked questions

How can I order 6N137M or check stock?

Submit an RFQ for the 6N137M with your target quantity. We source through franchised and independent channels; availability and lead time are confirmed at quote time. The part is active and ROHS3 compliant, so no lifecycle risk on new builds.

What is the difference between 6N137 and 6N137M?

The 6N137M is the through-hole DIP-8 variant of the 6N137 family. The base 6N137 shares the same 10Mbps data rate, 5000Vrms isolation, and open-collector output, but the 6N137M specifically ships in tube packaging and is the standard through-hole order code for onsemi's 6N137 series.
