The 18.8A peak pulse current at the 10/1000µs waveform gives the surge budget for a typical 24V system transient — but the 15V standoff means it triggers below the 24V rail, so it is not a primary clamp for a 24V bus. Use it on downstream 12V or 15V regulated rails. ## Active production, DO-214AC footprint Microchip continues to manufacture the part in the DO-214AC (SMA) package, supplied on Tape & Reel. The DO-214AC footprint is shared across the SMAJ family, so a BOM swap to a different voltage rating (e.g., SMAJ5.0 or SMAJ30) requires no board layout change — only the silkscreen marking.","metaTitle":"SMAJ15CE3/TR13 TVS Diode – 15V Bidirectional, 500W, DO-214AC","metaDescription":"SMAJ15CE3/TR13 bidirectional Zener TVS, 15V reverse standoff, 500W peak pulse, DO-214AC SMA package.
