SA6.0A Transient Voltage Suppressor (TVS) Diode — Equivalent & Substitute Parts

Part Overview

The SA6.0A is a 6V Zener transient voltage suppressor diode manufactured by onsemi in DO-204AC (DO-15) axial package configuration. This component is designed for general-purpose transient voltage suppression applications with a 10.3V maximum clamping voltage and 48.5A peak pulse current rating. The SA6.0A is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA6.0A are classified based on strict electrical and mechanical parameter alignment:

Direct Electrical Equivalents — Parts maintaining identical voltage ratings (6V reverse standoff, 6.67V minimum breakdown, 10.3V maximum clamping) and equivalent peak pulse current performance (48.5A to 50A range) within the same package family (DO-204AC/DO-15 axial).

Key Parameters Determining Substitutability:

• Voltage - Reverse Standoff: 6V (fixed requirement)
• Voltage - Clamping (Max) @ Ipp: 10.3V (fixed requirement)
• Current - Peak Pulse (10/1000µs): 48.5A minimum
• Power - Peak Pulse: 500W (fixed requirement)
• Package / Case: DO-204AC, DO-15, or Axial equivalent
• Mounting Type: Through Hole

Parts exceeding these electrical parameters within acceptable tolerances and maintaining identical package specifications qualify as functional substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Electrical Equivalents):

SA6.0A (Taiwan Semiconductor Corporation), SA6.0A-B (Littelfuse Inc.), SA6.0A-TP (Micro Commercial Co), and P5KE6.0A-AP (Micro Commercial Co) maintain the specified 6V reverse standoff voltage and 10.3V maximum clamping voltage with peak pulse current ratings between 48.5A and 50A. These parts are all active products with ROHS3 compliance or equivalent certifications, providing direct functional replacement for the obsolete onsemi SA6.0A.

Secondary Substitutes (Parameter Variance):

SAC6.0-E3/54, SAC6.0-E3/73 (Vishay General Semiconductor - Diodes Division), and SAC6.0-TP (Micro Commercial Co) maintain the 6V reverse standoff voltage but feature a higher maximum clamping voltage of 11.2V and reduced peak pulse current of 41A. These parts are suitable for applications where the higher clamping voltage is acceptable and peak pulse current requirements do not exceed 41A.

Compliance Considerations:

The original onsemi SA6.0A is RoHS non-compliant. All active substitute options listed provide ROHS3 compliance, supporting modern manufacturing and environmental regulatory requirements. Operating temperature ranges extend to 175°C for most active substitutes compared to the original 150°C specification, providing enhanced thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Can SA6.0A-TP be used as a direct replacement for SA6.0A?

A: Yes. SA6.0A-TP maintains identical voltage ratings (6V reverse standoff, 10.3V maximum clamping) and equivalent peak pulse current (49.5A). The primary difference is packaging format (Tape & Reel vs. bulk) and manufacturer (Micro Commercial Co vs. onsemi). Electrical performance is equivalent.

Q: What is the difference between SA6.0A and SAC6.0-E3/54?

A: Both maintain 6V reverse standoff voltage and 500W peak pulse power. SAC6.0-E3/54 has a higher maximum clamping voltage (11.2V vs. 10.3V) and lower peak pulse current (41A vs. 48.5A). SAC6.0-E3/54 is suitable for applications tolerating higher clamping voltages with lower current requirements.

Q: Are all substitute parts available in the same package?

A: Yes. All listed substitute parts use DO-204AC (DO-15) axial package configuration, maintaining identical through-hole mounting compatibility with the original SA6.0A.

Q: Does the operating temperature range affect substitutability?

A: Operating temperature range does not affect electrical substitutability. The original SA6.0A operates -55°C to 150°C. Most active substitutes extend to -55°C to 175°C, providing additional thermal margin without compromising compatibility in applications within the original temperature specification.

Q: Is RoHS compliance a substitution requirement?

A: RoHS compliance is not a functional electrical requirement for substitutability. However, all active substitute options provide ROHS3 compliance, supporting modern manufacturing standards and regulatory requirements. The original onsemi SA6.0A is RoHS non-compliant.

Q: Can P5KE6.0A-AP replace SA6.0A in all applications?

A: P5KE6.0A-AP maintains identical electrical specifications (6V reverse standoff, 10.3V maximum clamping, 48.5A peak pulse current) and package configuration. The extended operating temperature range (-65°C to 175°C) provides additional thermal capability. Functional replacement is equivalent across all specified parameters.
