TVS diode for 36V rails — 1500 W peak pulse, AEC-Q101 qualified
The 1.5SMBJ36A-H: It clamps at 58.1 V maximum and handles 25.9 A peak pulse current, with a 36 V reverse standoff voltage — sized for 36 V nominal DC bus or battery lines where the steady-state rail sits at or below 36 V. The -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles — the 150°C upper limit gives margin above the 125°C typical under-hood ambient.
Package and board-fit — DO-214AA (SMB) surface mount
Supplied in the DO-214AA (SMB) package, a standard surface-mount footprint shared across the 1.5SMBJ family. The SMB body measures roughly 4.6 mm × 3.6 mm with a 2.0 mm seated height — the same pad layout accepts the full 1.5SMBJ power range, so a single PCB land pattern serves multiple voltage variants in the series. Tape-and-reel packaging suits automated pick-and-place assembly.
Sourcing and compliance — active production, AEC-Q101 on record
Listed as Active — the manufacturer continues production. The AEC-Q101 qualification is the key compliance document for automotive BOMs; the part is RoHS-compliant per Bourns standard practice for this series.
