SA10AG Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SA10AG is a 10V reverse standoff, unidirectional Zener TVS diode manufactured by onsemi in the MiniMosorb™ series, rated for 17V clamping voltage and 29.4A peak pulse current. Designed for general-purpose transient voltage suppression in through-hole axial configurations, this component operates across -55°C to 150°C. The SA10AG is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain electrical and mechanical compatibility for ongoing circuit protection applications.

Substitute Part Grouping Explanation

Substitution eligibility for the SA10AG is determined by strict alignment across the following critical parameters:

Voltage - Reverse Standoff: 10V (exact match required)
Voltage - Clamping (Max) @ Ipp: 17V (exact match required)
Current - Peak Pulse (10/1000µs): 29.4A minimum (equal or greater acceptable)
Power - Peak Pulse: 500W minimum (equal or greater acceptable)
Mounting Type: Through Hole (required)
Package / Case: Axial or DO-15 compatible (required)
Type: Zener, Unidirectional (required)

Substitute parts are grouped into two categories:

Direct Equivalents: Parts meeting all electrical parameters with identical or superior current and power ratings, maintaining full functional interchangeability.

Similar Alternatives: Parts meeting core voltage parameters but with variations in current capacity, power dissipation, or temperature range, suitable for applications where the SA10AG's specific current rating is not a limiting constraint.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

SA10A, SA10A-E3/54, SA10A-TP, P5KE10A-AP, P5KE10A-BP, and P5KE10A-TP are direct electrical equivalents meeting or exceeding the SA10AG's 10V standoff, 17V clamping, and 29.4A peak pulse specifications. All are active products with RoHS3 compliance. SA10A-E3/54 and SA10AHE3/54 carry Vishay's TransZorb® series designation with extended temperature range to 175°C. P5KE series variants from Micro Commercial Co extend the lower operating temperature to -65°C. These parts are suitable for direct replacement in standard through-hole applications.

Secondary Alternatives (Functional Compatibility):

SAC10-AP maintains voltage parameters with marginally reduced clamping voltage (16.3V) and current capacity (29A), acceptable where peak pulse requirements are not critical. 1N8153 from Microchip Technology meets voltage specifications but delivers only 8.88A peak pulse and 150W power dissipation, limiting use to low-energy transient suppression. 5KP10A-G from Comchip Technology provides significantly elevated current (294.12A) and power (5kW) in R-6 package format, suitable for high-energy applications but not for standard through-hole axial mounting.

Compliance Considerations:

SA10A-E3/54, SA10A-TP, and SA10AHE3/54 carry RoHS3 compliance certification. SA10AHE3/54 includes AEC-Q101 automotive qualification. 1N8153 is RoHS non-compliant. All parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can SA10A directly replace SA10AG in existing designs?

A: Yes. SA10A matches the 10V standoff, 11.1V breakdown, and 17V clamping specifications with equivalent 30A peak pulse current. The extended temperature range (-55°C to 175°C versus -55°C to 150°C) provides additional operational margin. DO-204AC packaging is mechanically compatible with the original axial configuration.

Q: What is the difference between SA10A-E3/54 and SA10A-TP?

A: Both maintain identical electrical parameters (10V standoff, 17V clamping, 29.4A peak pulse). SA10A-E3/54 is supplied by Vishay in cut tape packaging with DO-204AC case format. SA10A-TP is supplied by Micro Commercial Co in tape and reel format with DO-15 case designation. Selection depends on packaging requirements and supplier availability.

Q: Is 1N8153 suitable as a substitute?

A: 1N8153 meets the 10V standoff and 17V clamping voltage requirements but delivers only 8.88A peak pulse current and 150W power dissipation compared to SA10AG's 29.4A and 500W. Use is restricted to applications where transient energy is limited and peak pulse current does not exceed 8.88A.

Q: Why does 5KP10A-G have such different specifications?

A: 5KP10A-G is a high-energy TVS variant rated for 294.12A peak pulse and 5kW power dissipation in R-6 package format. While voltage parameters align with SA10AG, the R-6 package is not compatible with standard through-hole axial mounting. This part addresses different application requirements involving higher transient energy levels.

Q: Are there temperature range limitations when substituting?

A: SA10AG operates to 150°C junction temperature. Most active substitutes extend to 175°C, providing additional thermal margin. P5KE10A variants extend the lower limit to -65°C. Verify application temperature requirements before selection. Extended temperature range does not restrict use in lower-temperature applications.

Q: What packaging formats are available?

A: SA10AG uses axial through-hole format. Direct substitutes are available in DO-204AC (equivalent to DO-15) and DO-15 designations, all compatible with through-hole mounting. 5KP10A-G uses R-6 package, incompatible with standard axial footprints. Confirm PCB footprint compatibility before procurement.

Q: Do all substitutes carry the same compliance certifications?

A: No. SA10A-E3/54, SA10A-TP, and SA10AHE3/54 carry RoHS3 compliance. 1N8153 is RoHS non-compliant. SA10AHE3/54 includes AEC-Q101 automotive qualification. Verify compliance requirements for your application before final selection.
