10 Mbps digital isolation with 5000 Vrms barrier
The onsemi 6N137TVM is a single-channel high-speed optocoupler rated for 10 Mbps data rates with a guaranteed 5000 Vrms isolation barrier — the safety isolation rating for reinforced insulation in mains-connected equipment. Its open-collector output with Schottky clamp translates the isolated logic signal to a standard TTL/CMOS level without an external pull-up resistor, and the 75 ns max propagation delay (tpLH / tpHL) keeps the timing budget tight for control-loop feedback or digital communication links.
Common-mode immunity and transient rejection
Minimum 10 kV/µs common-mode transient immunity (CMTI) means the 6N137TVM rejects fast voltage spikes between input and output sides — essential when the optocoupler bridges a noisy power stage (motor drive, inverter, SMPS) to a clean logic controller. The 30 ns rise and 10 ns fall typical edge rates combine with the 75 ns propagation delay to define the maximum usable data rate; at 10 Mbps the pulse width is 100 ns, so the output edge still settles within the bit period with margin for the downstream receiver's threshold.
Package and lifecycle status
The through-hole body suits prototyping, manual assembly, or high-vibration environments where a socketed or soldered DIP provides better mechanical retention than a surface-mount SOIC.
