Product details

Last-buy status — what it means for your BOM

The 1.5KE75CA-E3/51: Vishay has placed the 1.5KE75CA-/51 in Last Buy status — the manufacturer will accept final orders for a limited window, after which the part is discontinued. This is the time to secure lifetime-buy quantities or qualify a replacement.

Protection window: standoff, breakdown, and clamp

It clamps at 104V maximum with a peak pulse current of 14.6A, and its reverse standoff voltage is 64.1V — meaning a 64V rail sees no leakage under normal conditions, and the diode only conducts when a transient pushes the line above 71.3V (minimum breakdown).

Package and mounting — DO-201AA axial

Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The axial body is a standard footprint for TVS diodes in this power class — the leads are formed for through-hole insertion on a PCB or terminal block. Bulk packaging means the parts ship loose in a tube or bag, not on tape and reel.

Sourcing posture for the 1.5KE75CA-E3/51

Sourced through independent distribution channels. The Last Buy window means acting now avoids a forced redesign later.

Frequently asked questions

Where can I buy the 1.5KE75CA-/51 and how is it quoted?

Sourced through independent distribution channels. Submit an RFQ for your target quantity and delivery window.

What is the closest pin-compatible alternative to the 1.5KE75CA-/51?

The functional replacement would be another 1500W bidirectional TVS in a DO-201AA package with a 64V standoff voltage — but a board spin may be required if the replacement differs in electrical characteristics or footprint.
