Product details

TVS diode parametrics and protection window

The 1.5KE120CA-T: It protects a single line against transients up to 165 V clamping voltage, with a reverse standoff of 102 V and a minimum breakdown of 114 V. The 9.1 A peak pulse current rating (10/1000 µs) defines the surge capacity at the clamping voltage — a key parameter for selecting the TVS in a given transient environment.

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120CA-T is a through-hole device suited for point-to-point wiring or PCB mounting with through-hole pads. The DO-201 footprint is standard across many TVS families, simplifying layout reuse.

This makes it suitable for outdoor, under-hood, or high-reliability environments where thermal cycling is a concern. Diodes Incorporated lists this part as Obsolete. Sourcing is through independent distribution channels; availability and pricing are confirmed at RFQ against the BOM quantity.

Frequently asked questions

Where can I buy 1.5KE120CA-T and get a price?

The 1.5KE120CA-T is sourced to order against your BOM quantity through independent distribution.

What is the closest pin-compatible alternative to 1.5KE120CA-T?

For a functional replacement, evaluate other 1500 W bidirectional TVS diodes in the DO-201 package with a 102 V standoff and 165 V clamp — parametric matching is required.
