Product details

TVS diode for automotive transient protection

The 1.5SMC20CAHR7G: The single bidirectional channel in a DO-214AB (SMC) package simplifies board layout for symmetrical rail clamping — one component replaces two unidirectional diodes in series, saving placement cost and board area.

DO-214AB (SMC) surface-mount package with a standard JEDEC footprint — the cathode band is marked on the body; for a bidirectional part the marking is symmetrical and orientation is non-critical. Reflow profile follows standard Pb-free solder profiles per J-STD-020. The 1500W peak pulse rating assumes a copper pad area per the datasheet layout recommendation — a smaller pad raises the thermal impedance and derates the pulse-handling capability. The 10/1000µs waveform is the industry-standard test condition for TVS diodes; real-world pulse width and duty cycle affect the derating.

AEC-Q101 qualification is on file; the part is RoHS-compliant per Taiwan Semiconductor's standard declaration.
