SA6V5A-T Equivalent & Substitute Parts

Part Overview

The SA6V5A-T is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 6.5V reverse standoff voltage with an 11.2V maximum clamping voltage at peak pulse current. Designed for general-purpose transient protection in through-hole DO-15 packaging, this component is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the SA6V5A-T is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff (Typ): 6.5V
Voltage - Clamping (Max) @ Ipp: 11.2V
Current - Peak Pulse (10/1000µs): 44.7A minimum
Power - Peak Pulse: 500W
Type: Zener, Unidirectional
Mounting Type: Through Hole
Package / Case: DO-15 or DO-204AC (DO-15)

All substitute parts listed maintain identical electrical performance specifications and package compatibility. Variations in peak pulse current (44.7A to 46A) and operating temperature ranges remain within functional equivalence for general-purpose transient protection applications.

Frequently Asked Questions (FAQ)

Q: Can P5KE6.5A-BP and P5KE6.5A-TP be used interchangeably with SA6V5A-T?

A: Yes. Both P5KE6.5A variants maintain identical voltage ratings (6.5V reverse standoff, 11.2V clamping), peak pulse current (44.7A), and power dissipation (500W). The primary difference is packaging format: P5KE6.5A-BP is supplied in bulk, while P5KE6.5A-TP is supplied in tape and reel. Both are electrically equivalent.

Q: What is the difference between SA6.5A and SA6.5A-TP?

A: Both parts are manufactured by different suppliers (Taiwan Semiconductor Corporation vs. Micro Commercial Co) and have identical voltage and power specifications. SA6.5A has a peak pulse current of 46A, while SA6.5A-TP has 45.5A. Both exceed the original SA6V5A-T specification of 44.7A. Operating temperature ranges differ slightly: SA6.5A operates -55°C to 175°C, while SA6.5A-TP operates -55°C to 175°C (TA).

Q: Are the Vishay TransZorb® automotive-grade parts (SA6.5AHE3/54, SA6.5AHE3/73) necessary for general-purpose applications?

A: No. Automotive-grade qualification (AEC-Q101) is not required for general-purpose transient protection. These parts are suitable for applications requiring automotive-level reliability and traceability but are not mandatory for standard industrial or consumer applications.

Q: Does package format (DO-15 vs. DO-204AC) affect electrical performance?

A: No. DO-15 and DO-204AC are equivalent package designations for the same physical form factor. All listed parts are through-hole axial components with identical electrical characteristics regardless of package designation.

Q: Why is SA6V5A-T classified as obsolete?

A: The SA6V5A-T is obsolete due to manufacturer discontinuation. All listed substitute parts are active products from established manufacturers, ensuring long-term availability and supply chain continuity.
