The 1.5SMC47CA-M3/9AT: The single bidirectional channel means one DO-214AB package protects both polarities on a signal pair — useful for RS-485 or CAN bus lines where the common-mode range straddles ground.
The device is not intended for power-line protection — the spec explicitly flags No power line protection, so keep it on signal or low-voltage DC rails.
Vishay provides RoHS and REACH compliance documentation for this part. The 1.5SMC series is also UL recognized under file E54228. Specific certificates are available upon request.
