At that point it clamps to 64.5V maximum while shunting 9.3A peak pulse current in the standard 10/1000µs waveform. For a 40V bus, the margin between standoff and clamp is tight enough to protect downstream silicon rated at 60V or higher. ## Package and temperature range — SMB (DO-214AA) on tape The −65°C to 150°C junction temperature range covers military and industrial environments — the device conducts leakage well below 1 mA at 150°C, but the junction temperature rise from a single 600W pulse is brief enough to stay within the SOA. Supplied in Tape & Reel, the SMBJ40AE3/TR13 is ready for automated pick-and-place. ## Active lifecycle – no EOL watch needed Microchip lists the SMBJ40AE3/TR13 as Active.","metaTitle":"SMBJ40AE3/TR13 TVS Diode – 40V Standoff, 600W, DO-214AA","metaDescription":"Microchip Technology SMBJ40AE3/TR13 Zener TVS diode. 40V reverse standoff, 64.5V clamp at 9.3A, 600W peak pulse power.
