The 1.5SMBJ75A: The minimum breakdown voltage of 83.3 V provides a guard band above the 75 V reverse standoff, ensuring the diode stays off during normal operation and only conducts during a fault.
The operating junction temperature range spans -55°C to 150°C, covering the full automotive ambient envelope with margin for self-heating during a pulse.
The 1.5SMBJ series shares the same DO-214AA package footprint across all voltage variants, so a different voltage rating (e.g., 1.5SMBJ70A for a 70 V rail) is footprint-compatible but not functionally equivalent — the clamping voltage and breakdown thresholds differ.
As an AEC-Q101 qualified automotive-grade part, the 1.5SMBJ75A is manufactured under the same process controls and reliability testing as the rest of the 1.5SMBJ series. RoHS and REACH compliance documentation is standard from Bourns for this product family.
