SA8.0C-E3/54 Equivalent & Substitute Parts

Part Overview

The SA8.0C-E3/54 is a Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection applications. This component features an 8V reverse standoff voltage with a 15V maximum clamping voltage and 33.3A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The product is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SA8.0C-E3/54 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 8V (identical across all substitutes)
• Voltage - Breakdown (Min): 8.89V (identical across all substitutes)
• Bidirectional Channels: 1 (identical across all substitutes)
• Type: Zener (identical across all substitutes)
• Package / Case: DO-204AC, DO-15, Axial (identical across all substitutes)
• Operating Temperature Range: -55°C ~ 175°C (identical across all substitutes)
• Power - Peak Pulse: 500W (identical across all substitutes)

The substitute parts maintain the same electrical protection characteristics while offering variations in clamping voltage and peak pulse current within acceptable operational parameters for the same application category.

Parameter Comparison

Engineering Selection Recommendations

The SA8.0C-E3/54 is obsolete and no longer in active production. Both substitute parts maintain full electrical and mechanical compatibility with the original specification.

SA8.0CA-E3/54 is the direct manufacturer equivalent from Vishay General Semiconductor - Diodes Division, maintaining the same product lineage with active product status. This part is available in Cut Tape (CT) packaging with 3500 units in stock.

SA8.0CA from Taiwan Semiconductor Corporation is the manufacturer-recommended alternative, offering active product status with the highest inventory availability (13,790 units). This part is supplied in Tape & Reel (TR) packaging format.

Both substitutes are ROHS3 compliant, REACH unaffected, and maintain identical operating temperature ranges and power ratings. The primary differences are clamping voltage (13.6V versus 15V) and peak pulse current (36.8A to 38A versus 33.3A), both of which represent improved performance characteristics within the same application category.

Frequently Asked Questions (FAQ)

Q: Can SA8.0CA-E3/54 or SA8.0CA be used as direct replacements for SA8.0C-E3/54?

A: Yes. Both parts maintain identical reverse standoff voltage (8V), breakdown voltage (8.89V), operating temperature range (-55°C to 175°C), power rating (500W), and package format (DO-204AC axial through-hole). The substitute parts offer lower clamping voltage (13.6V) and higher peak pulse current (36.8A to 38A), representing equivalent or improved performance for general-purpose transient voltage suppression applications.

Q: What is the difference between SA8.0CA-E3/54 and SA8.0CA?

A: Both parts are electrically identical with the same voltage and current ratings. The primary differences are manufacturer (Vishay versus Taiwan Semiconductor Corporation), packaging format (Cut Tape versus Tape & Reel), and inventory availability. Selection depends on procurement requirements and packaging preferences for assembly operations.

Q: Are there packaging compatibility considerations?

A: All three parts use the same DO-204AC (DO-15) axial through-hole package format. Mechanical compatibility is maintained across all substitutes. Packaging format differences (Cut Tape versus Tape & Reel) affect only the supply method and do not impact circuit board assembly or electrical performance.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, with MSL rating of 1 (Unlimited). Compliance certifications are identical across SA8.0C-E3/54, SA8.0CA-E3/54, and SA8.0CA.

Q: Why do the substitute parts have lower clamping voltage?

A: The substitute parts (SA8.0CA-E3/54 and SA8.0CA) specify 13.6V maximum clamping voltage compared to 15V for the original SA8.0C-E3/54. Both values remain within acceptable operating parameters for 8V standoff voltage applications. The lower clamping voltage in substitutes represents tighter voltage regulation characteristics.
