SA6V5CA-T Equivalent & Substitute Parts

Part Overview

The SA6V5CA-T is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 6.5V reverse standoff voltage with 11.2V maximum clamping voltage and 44.7A peak pulse current in a DO-15 through-hole package. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the SA6V5CA-T are qualified based on the following electrical and mechanical parameters:

Voltage - Reverse Standoff: 6.5V (identical)
Voltage - Clamping (Max) @ Ipp: 11.2V (identical)
Current - Peak Pulse: 44.7A to 45.5A (within tolerance)
Power - Peak Pulse: 500W (identical)
Package / Case: DO-204AC or DO-15 (mechanically compatible)
Mounting Type: Through Hole (identical)
Type: Zener, Bidirectional, single channel (identical)

All substitute parts maintain the core electrical specifications required for transient voltage suppression in general-purpose applications. Packaging variants (bulk, cut tape, tape & reel) and manufacturer differences do not affect electrical performance or pin compatibility.

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, providing long-term availability compared to the obsolete SA6V5CA-T. Selection among substitutes depends on specific application requirements:

Direct Package Match (DO-15): P5KE6.5CA-AP, P5KE6.5CA-BP, P5KE6.5CA-TP, and SA6.5CA-TP provide identical DO-15 packaging and maintain the full operating temperature range of -65°C to 175°C, matching the original part's thermal specifications.

Alternative Package (DO-204AC): SA6.5CA, SA6.5CA-E3/54, and SA6.5CAHE3/54 use DO-204AC packaging (mechanically compatible as DO-15 equivalent) but operate within -55°C to 175°C. The SA6.5CAHE3/54 variant includes AEC-Q101 automotive qualification for applications requiring automotive-grade components.

Compliance Status: All substitute parts comply with RoHS3 and EAR99 export classifications. The SA6.5CAHE3/54 is the only variant with explicit automotive qualification (AEC-Q101).

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for SA6V5CA-T?

A: Yes, all listed parts are electrically equivalent based on voltage ratings (6.5V standoff, 11.2V clamping), peak pulse current (44.7A to 45.5A), and power dissipation (500W). Parts with DO-15 packaging (P5KE6.5CA series and SA6.5CA-TP) are direct mechanical replacements. Parts with DO-204AC packaging (SA6.5CA series) are mechanically compatible as DO-15 equivalents.

Q: What is the difference between DO-15 and DO-204AC packaging?

A: DO-15 and DO-204AC are equivalent axial through-hole packages for diodes. Both use identical lead spacing and hole diameter, making them mechanically interchangeable on PCBs. The designation difference reflects historical naming conventions from different manufacturers.

Q: Why do some parts have different peak pulse currents (44.7A vs 45.5A)?

A: The variation between 44.7A and 45.5A falls within the normal manufacturing tolerance for TVS diodes and does not affect circuit performance. Both values meet the 6.5V/11.2V voltage specification and 500W power rating.

Q: Which substitute should I choose for automotive applications?

A: The SA6.5CAHE3/54 is qualified to AEC-Q101 automotive standards and is the appropriate choice for automotive-grade designs. This part is available in tape & reel packaging and operates within -55°C to 175°C.

Q: Are there temperature range differences I should consider?

A: The original SA6V5CA-T and P5KE6.5CA series (AP, BP, TP variants) operate from -65°C to 175°C. The onsemi SA6.5CA and Vishay SA6.5CA series operate from -55°C to 175°C. For applications requiring the full -65°C lower limit, use P5KE6.5CA variants or SA6.5CA-TP.

Q: What packaging options are available?

A: Substitute parts are available in bulk, cut tape (CT), and tape & reel (TR) packaging. Bulk packaging is suitable for prototype and low-volume builds. Cut tape and tape & reel are standard for production assembly. All packaging variants contain electrically identical components.
