SMCJ6.0CA-13 Equivalent & Substitute Parts

Part Overview

The SMCJ6.0CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 6V reverse standoff voltage, 10.3V maximum clamping voltage, and 145.6A peak pulse current capability in a DO-214AB (SMC) package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ6.0CA-13 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 6V (nominal)
• Voltage - Breakdown (Min): 6.67V minimum
• Voltage - Clamping (Max) @ Ipp: 10.3V maximum
• Package / Case: DO-214AB, SMC (surface mount compatibility)
• Type: Zener diode, bidirectional, single channel
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical & Package Specifications): Parts with matching voltage ratings, clamping characteristics, and DO-214AB packaging that maintain full functional interchangeability.

Manufacturer Alternatives (Equivalent Performance, Different Peak Pulse Current): Parts meeting all voltage and package requirements but with higher peak pulse current ratings (145.7A or 291.3A), which provide enhanced transient protection capability while maintaining backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMCJ6.0CA-13-F (Diodes Incorporated)

This part is the direct functional equivalent of the discontinued SMCJ6.0CA-13, manufactured by the same supplier. It maintains identical electrical specifications (6V standoff, 10.3V clamping, 145.6A peak pulse) and DO-214AB packaging. The part is currently active in production and ROHS3 compliant, making it the preferred replacement for existing designs without modification.

Secondary Recommendations:

SMCJ6.0CA-E3/57T (Vishay General Semiconductor - Diodes Division) provides equivalent electrical performance with active product status and ROHS3 compliance. Vishay's TransZorb series offers established reliability in industrial applications.

SMCJ6.0CA-TP (Micro Commercial Co) meets all voltage and package requirements with extended operating temperature range (-55°C to 175°C) and ROHS3 compliance, suitable for applications requiring higher temperature operation.

SMDJ6.0CA (Alpha & Omega Semiconductor Inc.) offers enhanced transient protection with doubled peak pulse current (291.3A) and power dissipation (3000W) while maintaining identical voltage characteristics and DO-214AB packaging. This option is suitable for designs requiring increased margin against transient events.

Compliance Consideration:

All recommended active substitutes are ROHS3 compliant, addressing regulatory requirements that the original discontinued part does not meet.

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.0CA-13-F be used as a direct replacement for SMCJ6.0CA-13?

A: Yes. SMCJ6.0CA-13-F is electrically and mechanically identical to SMCJ6.0CA-13, with matching voltage ratings (6V standoff, 10.3V clamping), peak pulse current (145.6A), and DO-214AB packaging. The primary difference is product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between SMCJ6.0CA-13-F and SMCJ6.0CA-TP?

A: Both parts meet the core voltage and package requirements. SMCJ6.0CA-TP offers an extended operating temperature range (-55°C to 175°C versus -55°C to 150°C) and is manufactured by Micro Commercial Co rather than Diodes Incorporated. Peak pulse current is marginally higher (145.7A vs. 145.6A), which is within typical manufacturing tolerance.

Q: Why would SMDJ6.0CA be selected over other substitutes?

A: SMDJ6.0CA maintains identical voltage characteristics and DO-214AB packaging but provides doubled peak pulse current (291.3A) and power dissipation (3000W). This part is selected when designs require enhanced protection margin against higher-energy transient events while maintaining the same clamping voltage profile.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts use DO-214AB (SMC) surface-mount packaging, ensuring mechanical compatibility with existing PCB layouts. Packaging options (bulk, tape & reel, cut tape) vary by manufacturer and supplier, but the physical package footprint remains identical.

Q: What compliance certifications apply to the substitute parts?

A: All active substitute parts listed are ROHS3 compliant and REACH unaffected. The original SMCJ6.0CA-13 is RoHS non-compliant, making the substitutes necessary for applications subject to RoHS regulations.

Q: Can substitutes be mixed in the same design or production run?

A: Yes, all listed substitutes are electrically equivalent within the specified parameters and use identical DO-214AB packaging. However, design documentation and bill of materials should specify the selected part number to maintain traceability and ensure consistent sourcing.
