Product details

Automotive TVS for 12V rail protection

The 1.5SMC13A-AU_R1_000A1: The DO-214AB (SMC) package is the standard footprint for 1.5kW TVS diodes, compatible with reflow soldering profiles used in automotive PCB assembly.

Protection window and surge rating

The 11.1V reverse standoff voltage means the diode does not conduct at the normal 12V battery voltage, leaving the protected rail undisturbed. Breakdown occurs at 12.4V minimum, so the diode starts clamping before the rail exceeds the typical 16V load-dump ceiling for 12V systems. The 18.2V clamping voltage at 82A peak pulse current limits the transient energy that reaches downstream components. For a given transient energy, the clamping voltage determines the peak current the diode can handle — at 18.2V clamp, the 82A rating is consistent with the 1500W power limit.

Active lifecycle and sourcing posture

Panjit lists the 1.5SMC13A-AU_R1_000A1 as Active, so there is no last-time-buy pressure for current designs. The 1.5SMC-AU series covers multiple standoff voltages in the same DO-214AB footprint, so a BOM change to a different voltage variant would require a board-level review of the protection window.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC13A-AU_R1_000A1?

The 1.5SMC-AU series includes other standoff voltages in the same DO-214AB package, but a change in voltage rating requires verifying the protection window for the target rail.

What compliance documentation does Panjit provide for 1.5SMC13A-AU_R1_000A1?

The part is AEC-Q101 qualified for automotive applications. RoHS and REACH compliance documentation is typically available from Panjit; confirm at RFQ if specific certificates are needed for your compliance audit.
