The 500W peak pulse power rating at the standard 10/1000µs waveform defines the surge energy it can absorb — a 26.6A peak pulse current at the 18.8V clamping voltage gives the design engineer the numbers to confirm the TVS can handle the expected transient without exceeding junction temperature. ## Package and mounting — DO-214AC (SMA) on tape and reel The part ships in a Tape & Reel (TR) format for automated pick-and-place, in the DO-214AC (SMA) surface mount package. The SMA footprint is a standard JEDEC outline — the cathode band marks the unidirectional polarity, so the PCB silkscreen and the reel label must align with the circuit's ground reference. SMAJ10E3/TR13 carries an Active product status from Microchip Technology.","metaTitle":"SMAJ10E3/TR13 TVS Diode – 10V Standoff, 500W, DO-214AC","metaDescription":"SMAJ10E3/TR13 Zener TVS, 10V reverse standoff, 500W peak pulse, DO-214AC SMA package.
