Product details

1.5kW unidirectional TVS in DO-214AB

The 1.5SMCJ40AS_R1_00001: Its reverse standoff of 40 V sets the working voltage below which the device stays dormant — transients that exceed the 44.4 V minimum breakdown voltage trigger the clamping action, clamping at 64.5 V maximum to protect downstream circuitry.

SMC package for surface-mount board assembly

The DO-214AB (SMC) package mounts flush to the PCB with a solder reflow profile; the cathoded band marks the unidirectional polarity direction on the board. It ships in Tape & Reel or Cut Tape for standard pick-and-place assembly lines.

General-purpose protection for power and signal rails

Listed for general-purpose use, meaning it protects power rails, control lines, and data ports against lightning-induced transients and switching surges on the secondary side of a supply. It is not a power-line protection device — the datasheet confirms Power Line Protection: No.

Frequently asked questions

What does the 40V standoff and 64.5V clamping rating mean for my circuit?

The 40 V reverse standoff is the working voltage — below this the TVS leaks very little and the circuit sees no impact. When a transient exceeds the 44.4 V breakdown threshold, the device clamps the peak voltage at the protected node to no more than 64.5 V, limiting the energy delivered to downstream components.
