SA6.0C Equivalent & Substitute Parts

Part Overview

The SA6.0C is a 6V Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection in through-hole applications. This component features a 10.82V maximum clamping voltage and 49.5A peak pulse current capability in a DO-204AC (DO-15) axial package. The SA6.0C is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA6.0C are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff: 6V (identical across all substitutes)
• Voltage - Clamping (Max) @ Ipp: 10.3V to 10.82V (within acceptable operating range)
• Current - Peak Pulse (10/1000µs): 49.5A to 50A (equivalent pulse handling capability)
• Power - Peak Pulse: 500W (identical)
• Operating Temperature Range: -55°C ~ 175°C (identical or equivalent)
• Package / Case: DO-204AC (DO-15), Axial (identical mechanical form factor)
• Mounting Type: Through Hole (identical)
• Type: Zener, Bidirectional Channels: 1 (identical functional classification)

All substitute parts maintain the same electrical performance envelope and physical compatibility required for direct replacement in the SA6.0C application space.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (SA6.0CA, SA6.0CA-AP, SA6.0CA-BP, SA6.0CA-TP) are active products suitable for replacing the obsolete SA6.0C. Selection among these substitutes should be based on packaging and procurement requirements:

SA6.0CA (Taiwan Semiconductor Corporation) is available in Tape & Reel packaging with ROHS3 compliance and the highest inventory availability (300,200 pcs), making it the primary choice for high-volume production requirements.

SA6.0CA-TP (Micro Commercial Co) is supplied in Tape & Reel packaging with ROHS3 compliance and 895 pcs inventory, suitable for automated assembly processes requiring tape format.

SA6.0CA-AP and SA6.0CA-BP (Micro Commercial Co) are supplied in Bulk packaging with 807 pcs and 1,129 pcs inventory respectively, suitable for manual assembly or lower-volume applications.

All substitutes maintain REACH compliance status and identical ECCN/HTSUS classifications as the original SA6.0C.

Frequently Asked Questions (FAQ)

Q: Can SA6.0CA directly replace SA6.0C in existing designs?

A: Yes. The SA6.0CA maintains identical reverse standoff voltage (6V), equivalent clamping voltage (10.3V vs 10.82V), equivalent peak pulse current (50A vs 49.5A), and identical package form factor (DO-204AC/DO-15 axial). All electrical and mechanical parameters fall within the functional envelope of the original SA6.0C.

Q: What is the difference between SA6.0CA-TP, SA6.0CA-AP, and SA6.0CA-BP?

A: These three variants are electrically identical to SA6.0CA but differ in packaging format. SA6.0CA-TP is supplied in Tape & Reel format for automated pick-and-place assembly. SA6.0CA-AP and SA6.0CA-BP are supplied in Bulk format for manual assembly or lower-volume applications. All three maintain the same DO-15 axial package and electrical specifications.

Q: Are all substitute parts RoHS compliant?

A: SA6.0CA and SA6.0CA-TP are explicitly ROHS3 compliant. SA6.0CA-AP and SA6.0CA-BP do not specify RoHS status in the provided data. Verify RoHS compliance requirements with the supplier if this certification is mandatory for your application.

Q: What is the voltage difference between SA6.0C and its substitutes?

A: The SA6.0C has a maximum clamping voltage of 10.82V, while all substitutes (SA6.0CA variants) have a maximum clamping voltage of 10.3V. This 0.52V difference represents a lower clamping threshold, which provides improved transient suppression performance. Both values are within the 6V reverse standoff specification and maintain equivalent circuit protection.

Q: Can I use these substitutes interchangeably in my PCB design?

A: Yes. All substitute parts use the identical DO-204AC (DO-15) axial through-hole package with the same lead spacing and mechanical dimensions. No PCB layout modifications are required for substitution.
