1500W bidirectional TVS for 25.6V automotive rails
The 1.5SMC30CAHE3/57T: It clamps a 25.6V nominal rail at 41.4V maximum while conducting 36.2A peak pulse current. AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. The TransZorb® process delivers the fast response time needed for load-dump and inductive-switch transient suppression in engine control units, transmission modules, and body electronics.
Clamping window and thermal margin
The reverse standoff voltage of 25.6V allows the diode to sit across a 24V nominal bus without conducting leakage current. Breakdown occurs at a minimum of 28.5V, and clamping is guaranteed at 41.4V maximum — a 12.9V window from standoff to clamp that protects downstream silicon rated for 45V or higher. No power line protection flag indicates this part is intended for DC rails and signal lines, not AC mains rectification.
DO-214AB (SMC) surface-mount footprint
The JEDEC-standard footprint mates with existing SMC pad layouts; the cathode band is marked for orientation, though the bidirectional structure is polarity-insensitive. Supplied on tape and reel (TR) — the /57T suffix indicates 850-piece reel quantity. The reel is compatible with standard pick-and-place equipment; the moisture sensitivity level (MSL) is typically Level 1 for this package, meaning no bake required before reflow if the shelf life has not been exceeded.
