The 45 V reverse standoff voltage means it sits across a 45 V nominal rail without conducting until a transient pushes it into breakdown. The 500 W peak pulse power rating sets the energy-handling budget for a single surge event. ## Active production — no lifecycle concern Microchip lists the SMAJ45CAE3/TR13 as Active.","metaTitle":"SMAJ45CAE3/TR13 TVS Diode – 45 V Standoff, 500 W","metaDescription":"Microchip SMAJ45CAE3/TR13 Zener TVS: 45 V reverse standoff, 500 W peak pulse, bidirectional, DO-214AC (SMA).

The clamping voltage is symmetrical for positive and negative transients, so it does not require polarity orientation on the board."},{"question":"What is the peak pulse power of SMAJ45CAE3?","answer":"500 W peak pulse power measured with a 10/1000 µs waveform. For shorter pulse widths the peak power capability is higher; refer to the pulse derating curve in the datasheet for non-standard waveforms."},{"question":"What is the closest pin-compatible alternative to SMAJ45CAE3/TR13?","answer":"Any TVS in the SMAJ family with the same DO-214AC (SMA) package and bidirectional configuration is footprint-compatible.
