Product details

1500W Zener TVS for 12V rail protection

The 1.5KE12A-HF: It clamps a 10.2 V reverse standoff rail at 16.7 V maximum, passing up to 89.82 A of surge current through the DO-201AA axial package.

Clamping voltage and surge current

The 16.7 V maximum clamping voltage at 89.82 A peak pulse current (10/1000 µs) defines the protection level for a 12 V nominal bus — the TVS holds the transient below the downstream device's absolute maximum rating. The 10.2 V reverse standoff voltage means the diode stays off during normal operation and only conducts when the line exceeds that threshold. The through-hole DO-201AA package (axial leads) suits point-to-point wiring or PCB mounting with adequate copper pad area to sink the pulse heat.
