For repetitive events or longer pulse widths, the device's thermal capacity in the DO-214AC package limits the energy per event; the datasheet derating curve (not reproduced here) governs the safe operating area for repeated surges. ## Automotive temperature range and package fit The DO-214AC (SMA) surface-mount package uses a standard footprint shared across the SMAJ family — the same pad layout accepts the 5 V through 170 V variants, simplifying BOM consolidation when multiple rail voltages need protection on one board. Marked as Automotive applications, the part is qualified for the reliability stress and temperature cycling requirements of that sector. ## Sourcing and lifecycle posture The SMAJ family includes multiple voltage variants sharing the same DO-214AC footprint, but a different standoff voltage is not a functional substitute — the 85 V rating is specific to this order code.","metaTitle":"SMAJ85A-13 Diodes Inc TVS, 85V Standoff, 400W, DO-214AC","metaDescription":"SMAJ85A-13 Zener TVS from Diodes Inc, 85V reverse standoff, 137V clamp, 400W peak pulse, DO-214AC.
