SAC5.0-B Equivalent & Substitute Parts

Part Overview

The SAC5.0-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This through-hole component operates with a 5V reverse standoff voltage and provides 10V maximum clamping voltage at peak pulse current. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when electrical characteristics and mechanical specifications align with the main part's operational parameters, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SAC5.0-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 7.6V
• Voltage - Clamping (Max) @ Ipp: 10V
• Current - Peak Pulse (10/1000µs): 44A
• Power - Peak Pulse: 500W
• Package / Case: DO-204AC (DO-15), Axial
• Mounting Type: Through Hole
• Type: Zener
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C (TJ)

The substitute part SAC5.0-E3/54 meets all electrical and mechanical requirements for direct replacement. Packaging format differs (Cut Tape vs. Bulk), but the component specifications remain functionally identical.

Parameter Comparison

Engineering Selection Recommendations

The SAC5.0-E3/54 qualifies as a direct electrical and mechanical substitute for the SAC5.0-B based on identical voltage ratings, current handling, power dissipation, temperature range, and package specifications. Both components maintain active product status and full RoHS3 compliance.

Selection between the main part and substitute should be based on:

• Packaging requirements: SAC5.0-B is supplied in Bulk format; SAC5.0-E3/54 is supplied in Cut Tape (CT) format
• Inventory availability and lead time
• Cost considerations
• Supply chain preferences

No electrical performance differences exist between these components for the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can SAC5.0-E3/54 replace SAC5.0-B in existing circuit designs?

A: Yes. The SAC5.0-E3/54 meets all electrical specifications (5V standoff, 7.6V breakdown minimum, 10V clamping maximum, 44A peak pulse current, 500W peak power) and mechanical requirements (DO-204AC through-hole package, -55°C to 175°C operating range) required for direct substitution.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components loose in a container, while Cut Tape (CT) packaging provides components on continuous tape cut to specified lengths. Both formats contain identical components; packaging format selection depends on assembly process requirements and order quantities.

Q: Are there compliance differences between these parts?

A: No. Both SAC5.0-B and SAC5.0-E3/54 are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both components operate across the same temperature range (-55°C to 175°C junction temperature) with identical power dissipation ratings (500W peak pulse).

Q: Can I mix these parts in the same production batch?

A: Yes, provided your assembly process accommodates both Bulk and Cut Tape packaging formats. The electrical and mechanical specifications are identical, ensuring consistent circuit performance.
