SMCJ6.5CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ6.5CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 6.5V reverse standoff voltage and provides 12.3V clamping at peak pulse current, delivering 1500W peak pulse power dissipation in a DO-214AB (SMC) package. The part is Active in product status and RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers offering comparable electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ6.5CE3/TR13 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V (±0.01V tolerance acceptable)
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener
• Applications: General Purpose

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: 11.2V to 12.3V (lower clamping voltage provides enhanced protection margin)
• Current - Peak Pulse (10/1000µs): 122A to 267.9A (higher current rating maintains or exceeds protection capability)
• Power - Peak Pulse: 1500W to 3000W (higher power rating maintains or exceeds dissipation capability)
• Operating Temperature Range: Minimum -55°C acceptable (original -65°C provides extended low-temperature operation)
• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: MSL 1 (required)

Substitute parts are grouped into two categories based on power dissipation capacity: 1500W devices (SMCJ series) and 3000W devices (SMDJ and SMLJ series). Both categories satisfy the core electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed satisfy the core electrical and mechanical requirements for direct substitution with the SMCJ6.5CE3/TR13. Selection among qualified alternatives is based on the following engineering criteria:

1500W Power Rating Devices (SMCJ Series): SMCJ6.5CA (EVVO Semi), SMCJ6.5CA-13-F (Diodes Incorporated), SMCJ6.5CA-TP (Micro Commercial Co), and SMCJ6V5CA (Taiwan Semiconductor Corporation) maintain identical power dissipation capacity to the original part while offering lower clamping voltage (11.2V vs. 12.3V), which provides enhanced transient suppression margin. These devices are suitable for applications where the original 1500W specification is sufficient and where the lower clamping voltage is compatible with circuit design parameters.

3000W Power Rating Devices (SMDJ and SMLJ Series): SMDJ6.5CA (Alpha & Omega Semiconductor Inc.), SMLJ6.5CA (Bourns Inc.), and SMLJ6.5CA-TP (Micro Commercial Co) provide doubled power dissipation capacity (3000W) while maintaining the same voltage characteristics. These devices are suitable for applications requiring enhanced thermal margin or where higher transient energy absorption is anticipated.

Temperature Range Considerations: SMCJ6.5CA-TP and SMLJ6.5CA-TP extend the upper operating temperature to 175°C, compared to 150°C for most alternatives. The original SMCJ6.5CE3/TR13 operates to 150°C and extends to -65°C at the lower end. Applications requiring extended low-temperature operation (-65°C) should retain the original part or verify alternative temperature specifications against circuit requirements.

Product Status and Compliance: All substitute parts are Active in product status, RoHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance profile. All parts are REACH Unaffected or REACH Affected as specified, with EAR99 export classification and identical HTSUS coding (8541.10.0080).

Inventory Availability: Substitute parts demonstrate varying inventory levels: SMCJ6.5CA (38,100 pcs), SMCJ6.5CA-13-F (29,300 pcs), SMDJ6.5CA (61,300 pcs), and SMLJ6.5CA (1,952 pcs) offer substantial availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.5CA be used as a direct replacement for SMCJ6.5CE3/TR13?

A: Yes. SMCJ6.5CA meets all mandatory electrical parameters: 6.5V reverse standoff voltage, 7.22V breakdown voltage, DO-214AB SMC package, and surface-mount configuration. The lower clamping voltage (11.2V vs. 12.3V) provides enhanced protection margin. Operating temperature range is -55°C to 150°C, compared to the original -65°C to 150°C. Verify circuit design compatibility with the lower clamping voltage specification.

Q: What is the difference between SMCJ and SMDJ/SMLJ series devices?

A: SMCJ series devices (SMCJ6.5CA, SMCJ6.5CA-13-F, SMCJ6.5CA-TP, SMCJ6V5CA) are rated for 1500W peak pulse power dissipation, matching the original SMCJ6.5CE3/TR13 specification. SMDJ and SMLJ series devices (SMDJ6.5CA, SMLJ6.5CA, SMLJ6.5CA-TP) are rated for 3000W peak pulse power dissipation. All maintain identical voltage characteristics (6.5V reverse standoff, 11.2V clamping). Selection depends on thermal margin requirements and transient energy absorption capacity needed for the application.

Q: Are all substitute parts available in Tape & Reel packaging?

A: The original SMCJ6.5CE3/TR13 is supplied in Tape & Reel (TR) packaging. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® packaging. SMCJ6.5CA (EVVO Semi) is supplied in Cut Tape & Digi-Reel®. Verify packaging format compatibility with assembly equipment and procurement requirements.

Q: Can SMLJ6.5CA-TP be used in place of SMCJ6.5CE3/TR13?

A: Yes. SMLJ6.5CA-TP meets all mandatory electrical parameters and operates across -55°C to 175°C, extending the upper temperature limit by 25°C. Peak pulse power is doubled to 3000W, providing enhanced thermal margin. The part is RoHS3 compliant with MSL 1 rating. Verify that the higher power rating and extended temperature range do not introduce design conflicts in the target application.

Q: What is the significance of the lower clamping voltage in substitute parts?

A: The original SMCJ6.5CE3/TR13 clamps at 12.3V maximum, while most substitute parts (SMCJ6.5CA, SMCJ6.5CA-13-F, SMCJ6.5CA-TP, SMCJ6V5CA, SMDJ6.5CA, SMLJ6.5CA, SMLJ6.5CA-TP) clamp at 11.2V. Lower clamping voltage provides tighter transient suppression and enhanced protection of downstream components. Verify that the protected circuit can tolerate the lower clamping voltage without introducing false triggering or signal integrity issues.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant, matching the original SMCJ6.5CE3/TR13 compliance status. Moisture sensitivity level is MSL 1 (Unlimited) for all parts except SMCJ6V5CA, where MSL is not specified. REACH status varies: most parts are REACH Unaffected; SMLJ6.5CA is REACH Affected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the operating temperature range difference between substitute options?

A: The original SMCJ6.5CE3/TR13 operates from -65°C to 150°C. Most substitute parts operate from -55°C to 150°C, reducing the low-temperature specification by 10°C. SMCJ6.5CA-TP and SMLJ6.5CA-TP extend the upper limit to 175°C. SMCJ6V5CA does not specify operating temperature. Applications requiring -65°C operation should retain the original part or verify alternative specifications against circuit requirements.

Q: Can substitute parts with higher peak pulse current ratings be used interchangeably?

A: Yes. Substitute parts with higher peak pulse current ratings (134A, 133.9A, or 267.9A vs. original 122A) maintain or exceed the original protection capability. Higher current ratings indicate enhanced transient absorption capacity without introducing compatibility issues. The circuit design determines whether the higher current rating provides beneficial margin or is simply excess capacity.
