P6KE24A-E3/54 Equivalent & Substitute Parts

Part Overview

The P6KE24A-E3/54 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates with a reverse standoff voltage of 20.5V and provides clamping protection at 33.2V maximum, making it suitable for general-purpose transient suppression applications. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited or when design requirements permit selection from alternative manufacturers while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P6KE24A-TP be used as a direct replacement for P6KE24A-E3/54?

A: Yes. The P6KE24A-TP maintains identical electrical specifications including reverse standoff voltage (20.5V), breakdown voltage (22.8V), clamping voltage (33.2V), and power rating (600W). Both components use DO-15 packaging and are ROHS3 compliant.

Q: What is the primary difference between the 1.5KE24A and the P6KE24A-E3/54?

A: The 1.5KE24A provides higher current handling capacity (47A vs 18.1A) and increased power dissipation (1500W vs 600W) while maintaining identical voltage protection parameters. The package differs (DO-201 vs DO-15). Selection depends on application transient current requirements.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitutes use through-hole axial mounting. The P6KE24A-E3/54, P6KE24A-TP, and P6KE24A use DO-15 or DO-204AC packages. The 1.5KE24A uses DO-201 or DO-27 packages. All are compatible with through-hole PCB designs.

Q: Do all substitutes meet the same temperature operating range?

A: The P6KE24A-E3/54, P6KE24A-TP, and 1.5KE24A operate from -55°C to 175°C. The Fairchild P6KE24A operates from -50°C to 175°C, with a 5°C higher minimum temperature specification.

Q: Which substitute has the highest current availability?

A: The Fairchild P6KE24A has the highest inventory at 29400 pcs, followed by the 1.5KE24A at 14729 pcs, and the P6KE24A-TP at 2578 pcs.
