AEC-Q101 qualification and the -55°C to 150°C junction temperature range place this part squarely in under-hood and chassis-domain designs where the ambient sees 105°C and the junction sees the surge. The 40V minimum breakdown voltage gives margin above the 36V standoff — the device stays off until the transient pushes past that threshold. ## Clamping and surge handling on the bench The 58.1V clamp at 25.9A peak pulse current is the number that matters when you're sizing the downstream DC-DC or LDO input rating. A 60V-rated converter has 1.9V of headroom above the clamp — tight but workable if the layout inductance doesn't add another spike. The 1500W peak pulse rating is the 10/1000µs waveform; shorter pulses (8/20µs) let the device absorb significantly more energy before failure. Bidirectional configuration means a single part clamps both polarities — useful on AC-coupled signal lines or symmetric power rails where the transient can swing either direction. No power line protection is expected for a TVS in this class; it's a transient clamp, not a continuous overvoltage crowbar. ## Package and board integration DO-214AA (SMB) package — the same footprint as the standard SMB diode. The cathode band is marked for orientation, though for a bidirectional part the marking indicates the device is symmetric. The base product number 1.5SMBJ covers the full series; the -H suffix indicates the automotive grade variant with AEC-Q101 qualification. For volume procurement or spot-market checks, the 1.5SMBJ36CA-H is a standard Bourns part number with wide distribution coverage. The AEC-Q101 documentation package includes the PPAP and reliability report that automotive Tier-1 buyers require.","metaTitle":"Bourns 1.5SMBJ36CA-H TVS Diode, 1500W, 36V, DO-214AA","metaDescription":"Bourns 1.5SMBJ36CA-H bidirectional Zener TVS, 1500W peak pulse, 36V standoff, AEC-Q101 automotive grade.
