Product details

1500 W bidirectional TVS for telecom board protection

The 1.5SMC22CA V7G: This means a 24 V nominal bus sees no conduction during normal operation; the diode only starts clamping above 20.9 V and holds the line below 30.6 V during the surge event.

The DO-214AB package is widely second-sourced across the TVS industry, but no direct pin-compatible cross-reference from another manufacturer is recorded in the official spec.

Parametric fit for the BOM line

The bidirectional configuration (single channel) protects symmetrical signal pairs with one device instead of two back-to-back unidirectional diodes.
