SMCJ8.0CA-13 Equivalent & Substitute Parts

Part Overview

The SMCJ8.0CA-13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This zener-type TVS diode operates with an 8V reverse standoff voltage and provides 1500W peak pulse power dissipation in the DO-214AB (SMC) package. The part is active in production status and RoHS3 compliant.

Equivalent and substitute parts are identified based on matching or compatible electrical characteristics, including reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation ratings. Substitute parts may differ in packaging format, manufacturer, or operating temperature range while maintaining functional equivalence for the specified application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ8.0CA-13 are classified into two categories based on electrical and mechanical compatibility:

Category 1: Direct Electrical Equivalents (1500W Power Rating) These parts maintain identical or near-identical electrical specifications: 8V reverse standoff voltage, 13.6V clamping voltage, 110.3A peak pulse current, and 1500W power dissipation. Differences are limited to packaging format (Cut Tape versus Tape & Reel), manufacturer, or minor operating temperature variations. These parts are fully interchangeable in applications where the 1500W power rating is specified.

Category 2: Higher Power Alternatives (3000W Power Rating) These parts share the same voltage characteristics (8V standoff, 13.6V clamping) but provide double the power dissipation (3000W) and higher peak pulse current (220.6A). These are suitable for applications requiring greater transient energy absorption while maintaining the same voltage protection threshold.

The critical parameters determining substitution eligibility are:

• Voltage - Reverse Standoff: 8V
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (1500W Applications):

SMCJ8.0CA-13-F (Diodes Incorporated) is the primary equivalent, differing only in packaging format (Tape & Reel instead of Cut Tape). Both parts are manufactured by Diodes Incorporated, carry identical electrical specifications, and maintain ROHS3 compliance. This substitution is appropriate for high-volume production environments where Tape & Reel packaging is standard.

SMCJ8.0CA-E3/57T (Vishay General Semiconductor) provides equivalent electrical performance with ROHS3 compliance and Tape & Reel packaging. The part is part of the TransZorb® series and is suitable for applications requiring established supplier diversity.

SMCJ8.0CA-TP (Micro Commercial Co) offers the widest operating temperature range (-55°C to 175°C) while maintaining 1500W power rating and ROHS3 compliance. This part is selected for applications requiring extended high-temperature operation.

SMCJ8.0CA (Taiwan Semiconductor Corporation) provides equivalent voltage and power specifications with a marginally higher peak pulse current (115A versus 110.3A). ROHS3 compliance is maintained. High inventory availability (84,100 units) supports supply chain continuity.

For Higher Power Applications (3000W):

SMDJ8.0CA (Alpha & Omega Semiconductor Inc.) and SMLJ8.0CA (Bourns Inc.) both provide double the power dissipation (3000W) and double the peak pulse current (220.6A) while maintaining identical voltage protection characteristics. These parts are selected when application transient energy requirements exceed 1500W. Both maintain ROHS3 compliance and surface-mount DO-214AB packaging.

Compliance Considerations:

MSMCJ8.0CAE3 (Microchip Technology) is RoHS non-compliant and carries military-grade qualification (MIL-PRF-19500). This part is selected only for applications explicitly requiring military-grade components or where RoHS compliance is not mandated. The extended operating temperature range (-65°C to 150°C) supports military and aerospace applications.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.0CA-13-F be used as a direct replacement for SMCJ8.0CA-13?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications (8V standoff, 13.6V clamping, 110.3A peak pulse, 1500W power). The only difference is packaging format: SMCJ8.0CA-13 is supplied in Cut Tape, while SMCJ8.0CA-13-F is supplied in Tape & Reel. Both are ROHS3 compliant and suitable for surface-mount assembly.

Q: What is the difference between 1500W and 3000W TVS diodes in this voltage class?

A: The 1500W parts (SMCJ8.0CA series) and 3000W parts (SMDJ8.0CA, SMLJ8.0CA) maintain identical voltage protection characteristics (8V standoff, 13.6V clamping). The 3000W variants dissipate twice the transient energy and handle twice the peak pulse current (220.6A versus 110.3A). Selection depends on the magnitude of transient energy in the protected circuit.

Q: Is MSMCJ8.0CAE3 suitable for commercial applications?

A: MSMCJ8.0CAE3 is RoHS non-compliant and carries military-grade qualification (MIL-PRF-19500). It is not suitable for applications requiring RoHS3 compliance. This part is specified only for military, aerospace, or applications where RoHS exemption is documented.

Q: Which substitute part has the highest operating temperature rating?

A: SMCJ8.0CA-TP (Micro Commercial Co) operates from -55°C to 175°C, providing the widest high-temperature capability among 1500W equivalents. This part is selected for applications in high-temperature environments or equipment with elevated ambient conditions.

Q: Are all substitute parts available in DO-214AB (SMC) package?

A: Yes. All listed substitute parts use the DO-214AB (SMC) surface-mount package, ensuring mechanical and thermal compatibility with the original SMCJ8.0CA-13. Packaging format differences (Cut Tape, Tape & Reel, Bulk) affect supply and handling but not board-level compatibility.

Q: Can SMCJ8.0CA (Taiwan Semiconductor Corporation) be used interchangeably with SMCJ8.0CA-13?

A: Yes, with a minor specification difference. SMCJ8.0CA provides 115A peak pulse current compared to 110.3A in SMCJ8.0CA-13, representing a 4.3% increase. Both maintain 8V standoff, 13.6V clamping, and 1500W power rating. This part is suitable for direct replacement and offers high inventory availability.

Q: What compliance certifications should be verified before substitution?

A: Verify RoHS compliance status for your application. SMCJ8.0CA-13, SMCJ8.0CA-13-F, SMCJ8.0CA-E3/57T, SMCJ8.0CA-TP, SMCJ8.0CA, SMDJ8.0CA, and SMLJ8.0CA are all ROHS3 compliant. MSMCJ8.0CAE3 is RoHS non-compliant and carries military qualification. SMLJ8.0CA is REACH Affected; verify REACH compliance requirements for your end market.
