The 1.5SMC120A V7G: The 102 V reverse standoff voltage sits below the telecom bus voltage envelope, so the diode stays out of conduction during normal signalling; breakdown triggers at 114 V minimum, leaving a 12 V guard band before the clamping event.
The part is in standard production through Taiwan Semiconductor's distribution channel. The base product number 1.5SMC120 covers the full family; the V7G suffix denotes the tape-and-reel packaging variant.
