SA6.5CA-TP Equivalent & Substitute Parts

Part Overview

The SA6.5CA-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 at peak pulse current. The part is currently in active production status with robust inventory availability. Substitute parts are identified to provide design flexibility for procurement, inventory management, and supply chain continuity while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS diodes is determined by exact matching of critical electrical parameters that define protection performance and circuit compatibility. The SA6.5CA-TP and its identified substitute must maintain identical specifications across voltage ratings, peak pulse current capacity, and clamping characteristics. The key parameters governing substitution are:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 45.5A
• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• Package / Case: DO-204AC / DO-15 Axial

The substitute part SA6.5CA (onsemi) meets all electrical and mechanical requirements for direct substitution. Packaging differences (Cut Tape vs. Bulk) do not affect functional compatibility and represent only procurement and handling variations.

Engineering Selection Recommendations

Both SA6.5CA-TP and SA6.5CA are active production components with identical electrical performance and mechanical compatibility. Selection between these parts should be based on:

• Procurement requirements: SA6.5CA-TP is available in Cut Tape packaging (3,824 pcs in stock), while SA6.5CA is supplied in Bulk packaging (300,300 pcs in stock).
• Supply chain strategy: The onsemi SA6.5CA offers significantly higher inventory availability for high-volume applications.
• Compliance requirements: SA6.5CA-TP carries explicit ROHS3 Compliant certification. Compliance documentation for SA6.5CA should be verified through the manufacturer if regulatory compliance is a design requirement.
• Lead time and cost considerations: Bulk packaging typically offers cost advantages for production quantities.

Both parts are suitable for general-purpose transient voltage suppression applications requiring 6.5V standoff protection with 45.5A peak pulse current handling.

Frequently Asked Questions (FAQ)

Q: Can SA6.5CA replace SA6.5CA-TP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The SA6.5CA is a direct substitute with no circuit modifications required.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging is used for automated pick-and-place assembly and is supplied on tape reels. Bulk packaging is supplied loose in containers. Both contain identical components; packaging affects only handling and assembly processes.

Q: Are there any temperature rating differences between the two parts?

A: Both parts operate across -55°C to 175°C. The SA6.5CA-TP specifies TA (ambient temperature), while SA6.5CA specifies TJ (junction temperature). This represents different measurement reference points but does not affect functional performance or substitution eligibility.

Q: What compliance certifications apply to these parts?

A: SA6.5CA-TP is explicitly ROHS3 Compliant. Both parts carry EAR99 export classification and are REACH Unaffected. Compliance documentation for SA6.5CA should be obtained from onsemi if required for your application.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use identical DO-204AC / DO-15 axial through-hole packaging. PCB footprints, lead spacing, and mounting procedures are identical. No design changes are necessary.

Q: What is the peak pulse current rating, and why is it important?

A: Both parts are rated for 45.5A peak pulse current (10/1000µs waveform). This rating determines the maximum transient current the diode can suppress without damage. Ensure your application's transient current does not exceed this specification.
