The reverse standoff of 6.4 V typ means the TVS sits idle on the rail during normal operation, contributing no leakage burden; it only transitions into conduction when the transient pushes the line above that threshold. With a minimum breakdown of 7.13 V, the clamping margin — the gap between standoff and the start of avalanche — is tight enough that the designer must confirm the downstream bus tolerates the 7.13 V start-of-clamp before the diode fully engages at 11.3 V. ## Automotive grade — what AEC-Q101 and the 150 °C Tj ceiling mean AEC-Q101 qualification means this part passed the automotive stress suite — including humidity, temperature cycling, and surge repetition — making it acceptable for under-hood and chassis-domain boards that require IATF 16949 traceable components. Bidirectional — the CA suffix confirms the device clamps both polarities equally, which is the correct configuration for protecting a floating 12 V load bus or a signal line that sees bipolar transients. ## DO-214AB package and surface-mount assembly note The DO-214AB (SMC) package mounts flush to the PCB; the cathode tab must sit on a solid thermal pad — the datasheet recommended land pattern sets the pad width and solder mask definition, not the housing outline. Tape & Reel packaging suits high-volume pick-and-place lines; confirm the reel pitch matches your feeder — the 1.5SMC series uses the standard 330 mm reel diameter for SMC parts. The base product number 1.5SMC7.5 maps to the 7 V nominal Zener knee — the full 1.5SMC7.5CAHR7G order code specifies the automotive grade, the bidirectional CA variant, the R7 gift plating, and the G suffix which denotes AEC-Q101 / automotive process grade.","metaTitle":"Taiwan Semiconductor 1.5SMC7.5CAHR7G TVS Diode, 1.5kW 6.4V","metaDescription":"Taiwan Semiconductor 1.5SMC7.5CAHR7G bidirectional TVS Zener, 1.5kW peak pulse, 6.4V standoff, 11.3V clamping, AEC-Q101, DO-214AB.
