SA5V0A-T-F Equivalent & Substitute Parts

Part Overview

The SA5V0A-T-F is a 5V Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection applications. This unidirectional Zener diode features a 9.2V maximum clamping voltage and 54.3A peak pulse current capability in a through-hole DO-15 package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA5V0A-T-F is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Current - Peak Pulse (10/1000µs): minimum 54.3A
• Power - Peak Pulse: 500W (exact match required)
• Package / Case: DO-204AC or DO-15 (through-hole axial)
• Type: Zener, Unidirectional
• Applications: General Purpose

All substitute parts listed maintain identical voltage specifications and power ratings. Peak pulse current values may vary within acceptable engineering tolerances (54.3A to 57A). Operating temperature ranges may differ slightly between manufacturers but remain within acceptable industrial specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the SA5V0A-T-F and maintain active product status with full manufacturer support. Selection among substitutes should be based on:

SA5.0A-E3/54 (Vishay TransZorb®): Recommended for applications requiring established reliability history. Identical electrical specifications with 12,200 units in stock. Cut Tape packaging suitable for automated assembly.

SA5.0A (Taiwan Semiconductor Corporation): Recommended for high-volume applications. Largest inventory availability (300,100 units) with marginally higher peak pulse current (57A). Active product status with full compliance certifications.

SA5.0A-B (Littelfuse): Recommended for bulk procurement requirements. Peak pulse current of 55.4A with 4,178 units available. Bulk packaging option for cost-optimized sourcing.

SA5.0A-TP (Micro Commercial Co): Recommended for cut-tape applications. Peak pulse current of 55.4A with 7,297 units in stock. DO-15 package configuration with active product status.

All substitutes maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS coding. Operating temperature ranges for substitute parts are -55°C to 175°C, which is acceptable for most general-purpose applications. The original SA5V0A-T-F specified -65°C minimum; applications requiring extended low-temperature operation below -55°C should retain the original part or consult manufacturer specifications.

Frequently Asked Questions (FAQ)

Q: Can SA5.0A parts directly replace SA5V0A-T-F in existing designs?

A: Yes. All substitute parts maintain identical voltage specifications (5V standoff, 9.2V clamping), power ratings (500W peak pulse), and through-hole DO-15 package configuration. Peak pulse current values (54.3A to 57A) are within acceptable engineering tolerance for general-purpose TVS applications.

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

A: DO-15 and DO-204AC are equivalent designations for the same through-hole axial package. Both refer to the same physical form factor and pin configuration. All listed substitutes support both designations interchangeably.

Q: Does the operating temperature range difference affect substitution?

A: The original SA5V0A-T-F specifies -65°C to 175°C. Substitute parts specify -55°C to 175°C. For applications operating above -55°C, substitutes are fully equivalent. Applications requiring operation below -55°C should evaluate specific thermal requirements against manufacturer datasheets.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes (SA5.0A-E3/54, SA5.0A, SA5.0A-B, SA5.0A-TP) are ROHS3 compliant with identical REACH and ECCN classifications as the original part.

Q: Which substitute offers the best inventory availability?

A: Taiwan Semiconductor Corporation's SA5.0A offers the largest inventory (300,100 units) with active product status and identical electrical specifications.

Q: Can packaging format (Cut Tape vs. Bulk) affect electrical performance?

A: No. Packaging format affects only procurement and assembly logistics. Electrical specifications and performance are identical regardless of packaging configuration.
