SA60C Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SA60C is a bidirectional Zener TVS diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage suppression in through-hole applications. This component features a 60V reverse standoff voltage with a 101.64V maximum clamping voltage and 5.3A peak pulse current capability in a DO-204AC (DO-15) axial package. The SA60C is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA60C are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 60V (identical)
• Voltage - Breakdown (Min): 63.18V to 66.7V (within acceptable tolerance)
• Voltage - Clamping (Max) @ Ipp: 96.8V to 101.64V (functionally equivalent for transient suppression)
• Current - Peak Pulse (10/1000µs): 5.2A to 5.4A (equivalent pulse handling capability)
• Power - Peak Pulse: 500W (identical)
• Package / Case: DO-204AC, DO-15, Axial (identical mechanical form factor)
• Type: Zener, Bidirectional (identical functional classification)
• Operating Temperature Range: -55°C ~ 175°C or -65°C ~ 175°C (compatible thermal specifications)
• RoHS Status: ROHS3 Compliant (regulatory compliance maintained)

All substitute parts maintain the same functional voltage suppression characteristics and physical package compatibility required for direct replacement in through-hole circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are classified as Active products, ensuring long-term availability and manufacturing support compared to the obsolete SA60C. Each substitute maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The SA60CA from Taiwan Semiconductor Corporation and the SA60CA variants (SA60CA-AP, SA60CA-BP, SA60CA-TP) from Micro Commercial Co provide direct functional equivalence with identical reverse standoff voltage and compatible clamping voltage characteristics. The P5KE60CA-TP from Micro Commercial Co extends the lower operating temperature limit to -65°C, providing enhanced thermal performance for applications requiring extended cold-temperature operation.

Selection among active substitutes should be based on packaging preference (Tape & Reel versus Bulk), inventory availability, and specific thermal requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can SA60CA be used as a direct replacement for SA60C?

A: Yes. Both parts share identical reverse standoff voltage (60V), equivalent peak pulse current capability (5.4A versus 5.3A), and identical package form factor (DO-204AC/DO-15). The clamping voltage difference (96.8V versus 101.64V) remains within functional tolerance for general-purpose transient suppression applications.

Q: What is the difference between SA60CA-AP, SA60CA-BP, and SA60CA-TP?

A: These variants are functionally identical in electrical specifications. The suffix designations (AP, BP, TP) indicate different packaging or supplier configurations. All three maintain 60V reverse standoff, 96.8V clamping voltage, and 5.3A peak pulse current. Selection depends on packaging availability and procurement requirements.

Q: Does P5KE60CA-TP offer any advantage over SA60CA variants?

A: P5KE60CA-TP extends the lower operating temperature limit to -65°C compared to -55°C for SA60CA variants. This provides enhanced performance in applications requiring operation at lower ambient temperatures. Electrical suppression characteristics remain equivalent.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component use in regulated markets.

Q: What packaging options are available for substitutes?

A: SA60CA is available in Tape & Reel (TR) packaging. P5KE60CA-TP, SA60CA-AP, SA60CA-BP, and SA60CA-TP are available in Bulk packaging. All maintain the same DO-204AC/DO-15 axial through-hole form factor for mechanical compatibility.
