AEC-Q101 Zener TVS for 36V rail protection
The 1.5SMC36A-Q: The AEC-Q101 stamp means this part passed the automotive stress tests — temperature cycling, high-temperature reverse bias, and humidity — making it suitable for under-hood and chassis-domain electronics where a 36V nominal bus needs transient protection against load-dump and inductive kickback.
The package is marked with the cathode band and part number — orientation is unambiguous under a rework microscope. Power line protection is marked 'No' — this is a signal or low-power rail clamp, not a mains-side suppressor. Use it on 24V to 36V DC buses where the transient energy stays under the 1500W peak pulse envelope.
The part is supplied on Tape & Reel for automated pick-and-place assembly.
