SA6.5A-TP Equivalent & Substitute Parts

Part Overview

The SA6.5A-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole component operates with a 6.5V reverse standoff voltage and provides 11.2V maximum clamping voltage with 45.5A peak pulse current capability. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic designs requiring transient voltage suppression in the 6.5V protection range.

Equivalent and substitute parts are identified when they maintain identical or compatible electrical characteristics within the specified parameter tolerances while accommodating different packaging formats or manufacturer sourcing requirements.

Voltage - Clamping (Max) @ Ipp: 11.2V
Voltage - Breakdown (Min): 7.22V
Type: Zener, Unidirectional (1 channel)
Operating Temperature Range: -55°C to 175°C

Secondary Parameters (Allowable Variation):

Current - Peak Pulse: 45.5A or higher
Power - Peak Pulse: 500W or higher
Package / Case: DO-204AC, DO-15, DO-201 (all axial through-hole formats)

Compliance Requirements (Must Match):

RoHS Status: ROHS3 Compliant
Product Status: Active

Engineering Selection Recommendations

SA6.5A (Direct Equivalent): The SA6.5A from Taiwan Semiconductor Corporation is a direct electrical equivalent to the SA6.5A-TP. Both parts maintain identical voltage specifications (6.5V standoff, 7.22V breakdown, 11.2V clamping) and equivalent current ratings (45.5A vs. 46A). Both are ROHS3 compliant, actively produced, and support the same package formats (DO-204AC, DO-15). This part is suitable for direct substitution when sourcing from Taiwan Semiconductor Corporation is preferred or when Micro Commercial Co inventory is unavailable.

LCE6.5A (Compatible Substitute): The LCE6.5A from Littelfuse Inc. maintains identical voltage protection characteristics (6.5V standoff, 7.22V breakdown, 11.2V clamping) and exceeds the current and power ratings of the main part (100A vs. 45.5A; 1500W vs. 500W). This part is ROHS3 compliant and actively produced. The LCE6.5A uses a different package format (DO-201AA, DO-27) compared to the SA6.5A-TP (DO-15). Selection of this substitute requires verification that the larger DO-201 package dimensions are compatible with the PCB layout and mechanical constraints of the application.

Frequently Asked Questions (FAQ)

Q: Can SA6.5A be used as a direct replacement for SA6.5A-TP? A: Yes. Both parts share identical voltage specifications (6.5V standoff, 11.2V clamping) and equivalent current ratings (45.5A vs. 46A). Both support DO-15 packaging and are ROHS3 compliant. The primary difference is the manufacturer (Taiwan Semiconductor Corporation vs. Micro Commercial Co).

Q: What are the key differences between SA6.5A and LCE6.5A? A: Both maintain identical voltage protection levels (6.5V standoff, 11.2V clamping). The LCE6.5A provides higher current capacity (100A vs. 46A) and higher power dissipation (1500W vs. 500W). The LCE6.5A uses DO-201 packaging, which is physically larger than the DO-15 package used by SA6.5A. Selection depends on available PCB space and current handling requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. SA6.5A and LCE6.5A are both ROHS3 compliant, matching the compliance status of the SA6.5A-TP.

Q: Can LCE6.5A be used in applications designed for SA6.5A-TP? A: Electrical compatibility is confirmed (identical voltage specifications). However, the DO-201 package is physically larger than DO-15. PCB layout verification is required to confirm that the larger package dimensions do not conflict with existing component placement or mechanical constraints.

Q: What is the operating temperature range for all substitute parts? A: All parts operate across -55°C to 175°C, providing identical thermal performance specifications.
