Rated for 500W peak pulse power at the 10/1000µs waveform, it can handle a peak pulse current of 32.6A before the clamping voltage reaches 15.4V max. That clamping ceiling is what the downstream circuitry must survive — if your 9V rail has a 16V absolute-maximum input on the regulator, this part buys you a solid margin. The part is unidirectional with a single Zener channel, so it clamps only positive transients relative to ground. For AC or bidirectional protection, you would need two devices back-to-back or a dedicated bidirectional TVS. Microchip lists the SMAJ9.0AE3/TR13 as Active, meaning no end-of-life notice is in effect. The suffix indicates RoHS compliance and tin-lead (SnPb) termination finish — verify your assembly's solder alloy compatibility if moving to lead-free-only processes.","metaTitle":"SMAJ9.0AE3/TR13 TVS Diode – 9V Zener, 500W, DO-214AC","metaDescription":"SMAJ9.0AE3/TR13 Zener TVS diode, 9V reverse standoff, 500W peak pulse, DO-214AC (SMA) package.

The suffix indicates RoHS compliance and tin-lead termination; the TR13 suffix specifies Tape & Reel packaging. Electrically, both share the same 9V standoff, 500W peak pulse, and DO-214AC package — the difference is the termination finish and reel format."},{"question":"Is the SMAJ9.0AE3/TR13 RoHS compliant?","answer":"Yes, the suffix in the part number denotes RoHS compliance.
