1500 W bidirectional TVS for 12 V rail protection
The 1.5KE13CA/54: It clamps at 18.2 V maximum and handles 82.4 A peak pulse current — sized for protecting 12 V nominal DC rails in industrial and general-purpose equipment.
Clamping voltage and breakdown thresholds
Reverse standoff voltage is 11.1 V typical, meaning the diode stays off below that level and does not load the protected rail. Breakdown voltage starts at 12.4 V minimum, and clamping is held to 18.2 V at the full 82.4 A peak pulse current — the energy is shunted before it reaches downstream silicon. As a single bidirectional channel, this part clamps both polarities symmetrically — useful on AC signal lines or dual-polarity supplies where a unidirectional TVS would need two parts back-to-back.
Obsolete — sourcing through independent channels
Vishay has marked the 1.5KE13CA/54 as obsolete. No official successor order code is listed. The DO-201AA axial footprint is shared by many active TVS diodes from other manufacturers if a redesign is an option.
Package and temperature range
Housed in the DO-201AA (DO-27) axial-lead package, it mounts through-hole on a PCB or terminal strip.
