SA130 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SA130 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. The device features a 130V reverse standoff voltage with a 219.45V maximum clamping voltage at peak pulse current and is housed in a DO-204AC (DO-15) axial through-hole package. The SA130 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the SA130 is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff: 130V (exact match required)
Voltage - Clamping (Max) @ Ipp: 209V to 219.45V (acceptable range)
Current - Peak Pulse (10/1000µs): 2.4A (exact match required)
Power - Peak Pulse: 500W (exact match required)
Type: Zener, unidirectional (exact match required)
Package / Case: DO-204AC, DO-15, Axial (exact match required)
Mounting Type: Through Hole (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the SA130 in general-purpose transient voltage suppression applications.

Engineering Selection Recommendations

All substitute parts listed above are electrically equivalent to the SA130 and meet the specified electrical and mechanical parameters for direct substitution in general-purpose transient voltage suppression circuits.

For new designs and ongoing production, parts with Active product status are preferred over obsolete alternatives. The P5KE130A series (P5KE130A-TP, P5KE130A-AP, P5KE130A-BP) and SA130A series (SA130A-TP, SA130A-AP, SA130A-BP) from Micro Commercial Co are all currently active and available in multiple packaging configurations.

The P5KE130A and SA130A variants from Micro Commercial Co offer an extended lower operating temperature limit of -65°C compared to the SA130's -55°C minimum, providing additional thermal margin in cold-environment applications.

Packaging selection should be based on procurement and assembly requirements: Tape & Reel (TR) for automated pick-and-place assembly, Tape & Box (TB) for mixed-volume orders, and Bulk for manual assembly or stock applications.

Frequently Asked Questions (FAQ)

Q: Can SA130A be used as a direct replacement for SA130?

A: Yes. SA130A meets all critical electrical parameters: 130V reverse standoff voltage, 209V clamping voltage (within the acceptable range), 2.4A peak pulse current, and 500W peak pulse power. Both devices use identical DO-204AC (DO-15) axial through-hole packaging and are rated for -55°C to 175°C operation.

Q: What is the difference between P5KE130A and SA130A variants?

A: Both series are electrically equivalent with identical voltage and current ratings. The primary differences are packaging options (Tape & Reel, Tape & Box, or Bulk) and manufacturer designation. P5KE130A variants support an extended lower operating temperature of -65°C, while SA130A variants maintain the -55°C minimum of the original SA130.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed meet ROHS3 compliance requirements and are suitable for applications requiring RoHS certification.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (Tape & Reel, Tape & Box, or Bulk) affects only procurement, storage, and assembly methods. Electrical performance and specifications remain identical across all packaging variants of the same part number base.

Q: Which substitute part should be selected for new production?

A: For new designs, select from active-status parts: P5KE130A-TP (Tape & Reel), P5KE130A-AP (Tape & Box), P5KE130A-BP (Bulk), SA130A-TP, SA130A-AP, or SA130A-BP. Choose packaging based on assembly process requirements. The P5KE130A series offers -65°C minimum operating temperature for enhanced cold-temperature performance.
