Product details

What 1.5SMC75CA V7G is — and why the clamping spec decides the design

The 1.5SMC75CA V7G is a bidirectional TVS Zener in the 1.5SMC series from Taiwan Semiconductor Corporation — it clamps transient voltage spikes to protect sensitive telecom circuits. The reverse standoff of 64.1 V typ sets the working voltage the line normally sits at; the 71.3 V minimum breakdown is where the device begins conducting — the window between standoff and breakdown is the designer's headroom for the protected rail.

Telecom deployment and the wide junction temperature range

Tape & Reel packaging suits automated assembly at volume.

Active production, sourcing posture

The base product number 1.5SMC75 identifies the voltage selection within the series — any second-source or cross-reference must match the same standoff, breakdown, and clamping voltage ratings.

Frequently asked questions

What voltage does the 1.5SMC75CA V7G actually clamp at under surge?

The maximum clamping voltage is 103 V at the rated peak pulse current of 15 A (10/1000 µs waveform). The reverse standoff sits at 64.1 V typ, with a minimum breakdown of 71.3 V.

What package does 1.5SMC75CA V7G use and is it standard for pick-and-place?

It ships in the DO-214AB (SMC) surface-mount package on Tape & Reel — a standard footprint for telecom board assembly with standard reflow profiles.
