Breakdown is guaranteed between 37.1V minimum, so the protection triggers before the rail exceeds the downstream components' absolute maximum ratings. The AEC-Q101 qualification adds the reliability screening (PPAP, temperature cycling, ESD) required for Tier-1 production releases. ## DO-214AB (SMC) surface-mount package Housed in the standard DO-214AB (SMC) package — a JEDEC-registered footprint shared across the 1.5SMC family. The bidirectional configuration uses a single die in a two-terminal package, so board layout is identical to the unidirectional variant; the cathode band is omitted. The SMC body handles the 1500W pulse without exceeding the package's thermal limit — the copper pad area under the tab sets the effective RthJA for repetitive events. ## Active production — sourcing for automotive BOMs Targeted at Automotive and Telecom applications per the series definition. The AEC-Q101 certification means the part ships with full lot traceability and the documented reliability data that procurement and quality teams require for PPAP submissions.","metaTitle":"Bourns 1.5SMC39CA-Q TVS Diode, 33.3V Standoff, DO-214AB","metaDescription":"Bourns 1.5SMC39CA-Q bidirectional Zener TVS, 1500W peak pulse, 33.3V standoff, AEC-Q101 qualified.
