SA64C-E3/54 Equivalent & Substitute Parts

Part Overview

The SA64C-E3/54 is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This through-hole component operates with a 64V reverse standoff voltage and provides 114V maximum clamping voltage at peak pulse current. The device is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA64C-E3/54 is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage: 64V (identical)
• Breakdown voltage minimum: 71.1V (identical)
• Peak pulse power rating: 500W (identical)
• Operating temperature range: -55°C to 175°C (identical)
• Mounting type: Through hole (identical)
• Package / case: DO-204AC (DO-15), Axial (identical)
• Bidirectional channels: 1 (identical)
• Type: Zener (identical)

Acceptable variations within substitution criteria:

• Clamping voltage (Max) @ Ipp: 103V to 114V (lower clamping voltage provides improved transient suppression performance)
• Peak pulse current (10/1000µs): 4.4A to 5A (higher current capability maintains or exceeds protection capacity)

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (SA64CA-E3/54, SA64CA, and SA64CA-TP) meet the core electrical and mechanical requirements for direct substitution of the obsolete SA64C-E3/54.

SA64CA-E3/54 (Vishay General Semiconductor): Active product status with ROHS3 compliance and MSL 1 rating. Maintains manufacturer continuity with the original part. Clamping voltage reduced to 103V with peak pulse current increased to 4.9A, providing enhanced transient suppression performance.

SA64CA (Taiwan Semiconductor Corporation): Active product status with ROHS3 compliance and MSL 1 rating. Highest inventory availability (5400 pcs). Peak pulse current rated at 5A with 103V clamping voltage, delivering maximum protection capacity within the substitution parameters.

SA64CA-TP (Micro Commercial Co): Active product status with REACH compliance. Supplied in bulk packaging format. Peak pulse current rated at 5A with 103V clamping voltage. RoHS and MSL specifications not provided in documentation.

Selection between these three alternatives depends on procurement requirements, packaging format preference, and compliance documentation availability for your application.

Frequently Asked Questions (FAQ)

Q: Can SA64CA-E3/54, SA64CA, or SA64CA-TP be used as direct replacements for SA64C-E3/54?

A: Yes. All three substitute parts maintain identical reverse standoff voltage (64V), breakdown voltage (71.1V), peak pulse power (500W), operating temperature range (-55°C to 175°C), mounting type (through hole), and package format (DO-204AC / DO-15). The substitutes feature improved or equivalent peak pulse current ratings (4.9A to 5A versus 4.4A) and lower clamping voltage (103V versus 114V), which enhances transient suppression performance.

Q: What is the difference between the three substitute parts?

A: The primary differences are manufacturer identity, product status (all active), packaging format (tape & reel or bulk), and compliance documentation. Electrical performance is equivalent across all three. SA64CA offers the highest inventory availability. SA64CA-E3/54 maintains Vishay manufacturer continuity. SA64CA-TP is supplied in bulk format.

Q: Does the reduced clamping voltage (103V vs. 114V) on substitute parts affect circuit protection?

A: No. Lower clamping voltage indicates improved transient suppression performance. The substitute parts clamp transient voltages at 103V maximum, compared to 114V on the original part, providing better protection margins for downstream components.

Q: Are the substitute parts RoHS compliant?

A: SA64CA-E3/54 and SA64CA are both ROHS3 compliant. RoHS compliance status for SA64CA-TP is not specified in available documentation. Verify compliance requirements for your specific application before selection.

Q: What packaging formats are available?

A: SA64CA-E3/54 and SA64CA are supplied in tape & reel (TR) format. SA64CA-TP is supplied in bulk format. Select based on your assembly process requirements and volume needs.
