SA10CA-B Equivalent & Substitute Parts

Part Overview

The SA10CA-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This through-hole component operates with a 10V reverse standoff voltage and provides 17V maximum clamping voltage at peak pulse current. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical parameters and mechanical compatibility align within the allowed specifications for this TVS diode category.

Substitute Part Grouping Explanation

Substitute parts for the SA10CA-B are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 10V to 10.2V range
• Voltage - Clamping (Max) @ Ipp: 16.7V to 17V range
• Current - Peak Pulse (10/1000µs): 29.4A minimum
• Power - Peak Pulse: 500W minimum
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 (Axial)
• Operating Temperature: -55°C minimum to 175°C maximum
• RoHS Status: ROHS3 Compliant

Parts meeting these parameters are electrically and mechanically compatible for direct substitution in applications designed for the SA10CA-B.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance, meeting regulatory requirements equivalent to the SA10CA-B. Selection among qualified substitutes should be based on:

SA10CA (Taiwan Semiconductor Corporation): Identical electrical specifications to the SA10CA-B with matching voltage and current parameters. Available in Tape & Reel packaging for automated assembly processes.

SA10CA-E3/54 (Vishay General Semiconductor - Diodes Division): Meets all electrical requirements with peak pulse current of 29.4A, within the acceptable range. Available in Cut Tape packaging. Operates under the TransZorb® series designation.

P6KE12CA (Taiwan Semiconductor Corporation): Operates within the acceptable voltage range (10.2V standoff, 16.7V clamping) with enhanced peak pulse current capability of 36A and increased power dissipation of 600W. Operating temperature range not specified in available data. Available in Cut Tape packaging.

Frequently Asked Questions (FAQ)

Q: Can SA10CA-B be directly replaced with SA10CA? A: Yes. The SA10CA from Taiwan Semiconductor Corporation provides identical electrical specifications (10V standoff, 17V clamping, 30A peak pulse current) and operates within the same temperature range. The primary difference is packaging format (Tape & Reel versus Bulk).

Q: What is the difference between SA10CA-E3/54 and SA10CA-B? A: The SA10CA-E3/54 from Vishay maintains equivalent voltage specifications and operates at 29.4A peak pulse current, which is within acceptable tolerance for this application category. Both are through-hole DO-204AC/DO-15 packages with identical operating temperature ranges and RoHS3 compliance.

Q: Is P6KE12CA a suitable substitute for SA10CA-B? A: The P6KE12CA operates within the acceptable voltage range with a slightly higher standoff voltage (10.2V) and lower clamping voltage (16.7V). It provides enhanced current handling (36A) and power dissipation (600W). Operating temperature data is not provided for this part. Compatibility depends on application-specific requirements for voltage tolerance and thermal performance.

Q: What packaging options are available for substitutes? A: SA10CA is supplied in Tape & Reel format for automated assembly. SA10CA-E3/54 and P6KE12CA are supplied in Cut Tape format. The original SA10CA-B is supplied in Bulk packaging. All maintain the same through-hole DO-204AC/DO-15 axial package form factor.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting the same regulatory requirements as the SA10CA-B.
