SMCJ15CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ15CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a 15V reverse standoff voltage and provides clamping at 26.9V maximum, with a peak pulse current rating of 55.8A and peak pulse power of 1500W. The device is housed in a DO-214AB (SMC) surface mount package and is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics within the 15V protection class, compatible surface mount packaging, and active product status. Substitutes may vary in peak pulse current capacity, clamping voltage, and power dissipation ratings while maintaining the same reverse standoff voltage and breakdown voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ15CE3/TR13 are qualified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 15V
• Voltage - Breakdown (Min): 16.7V
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• Package / Case: DO-214AB or SMC equivalent

Secondary Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: 24.4V to 26.9V (acceptable range for 15V class devices)
• Current - Peak Pulse (10/1000µs): 55.8A to 205A (higher ratings provide enhanced transient protection)
• Power - Peak Pulse: 1500W to 5000W (higher ratings accommodate greater energy dissipation)
• Operating Temperature Range: -65°C to 175°C (extended ranges acceptable)

All substitute parts maintain active product status, RoHS3 compliance, and MSL 1 rating. Substitutes are grouped by manufacturer and peak pulse current capacity to facilitate selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Same Peak Pulse Current):

The SMCJ15CA (EVVO Semi) and SMCJ15CA-13-F (Diodes Incorporated) provide direct electrical equivalence to the SMCJ15CE3/TR13 with identical peak pulse current (61.5A) and power dissipation (1500W). Both devices maintain the 15V reverse standoff voltage and 16.7V minimum breakdown voltage. The SMCJ15CA-13-F from Diodes Incorporated offers the advantage of Tape & Reel packaging with confirmed REACH compliance status. Operating temperature range for SMCJ15CA is -55°C to 150°C, while SMCJ15CA-13-F operates -55°C to 150°C. The original SMCJ15CE3/TR13 extends to -65°C minimum temperature.

Enhanced Current Capacity Substitutes:

The SMDJ15CA-T7 (Littelfuse) and SMLJ15CA (Bourns Inc.) provide doubled peak pulse current (123A) and tripled power dissipation (3000W) while maintaining the same 15V protection class. SMDJ15CA-T7 operates across -65°C to 150°C, matching the original temperature range. SMLJ15CA operates -55°C to 150°C. These devices are suitable for applications requiring higher transient energy absorption.

Maximum Current Capacity Substitutes:

The 5.0SMDJ15CA (MDE Semiconductor Inc) and 5.0SMDJ15CA-T7 (Littelfuse) deliver the highest peak pulse current (205A) and power dissipation (5000W) in the 15V class. The 5.0SMDJ15CA-T7 from Littelfuse maintains the full -65°C to 150°C operating range of the original device and provides REACH compliance confirmation. These devices are appropriate for high-energy transient protection applications.

All substitute parts maintain RoHS3 compliance and MSL 1 rating. Selection should be based on application transient energy requirements and thermal operating environment constraints.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SMCJ15CE3/TR13 with any of the listed parts?

A: Substitution is permissible only when the application requirements align with the substitute part's electrical specifications. All listed substitutes maintain the 15V reverse standoff voltage and 16.7V minimum breakdown voltage, ensuring compatibility with 15V protection class circuits. However, differences in peak pulse current (55.8A to 205A) and power dissipation (1500W to 5000W) must be evaluated against the specific transient energy profile of the application.

Q: What is the difference between the SMCJ15CA and SMDJ15CA-T7?

A: Both devices maintain identical voltage specifications (15V reverse standoff, 16.7V breakdown, 24.4V clamping). The primary difference is peak pulse current: SMCJ15CA provides 61.5A with 1500W power dissipation, while SMDJ15CA-T7 provides 123A with 3000W power dissipation. SMDJ15CA-T7 is suitable for applications requiring higher transient current handling. Both are manufactured by different suppliers (EVVO Semi vs. Littelfuse) and may have different lead times and availability.

Q: Are the 5.0SMDJ15CA series parts compatible with the original SMCJ15CE3/TR13?

A: Yes, the 5.0SMDJ15CA and 5.0SMDJ15CA-T7 are electrically compatible for 15V protection applications. Both maintain the required 15V reverse standoff and 16.7V breakdown voltages. The primary advantage is significantly higher peak pulse current (205A) and power dissipation (5000W), making these devices suitable for high-energy transient environments. The 5.0SMDJ15CA-T7 from Littelfuse maintains the -65°C to 150°C operating range of the original device.

Q: Does operating temperature range affect substitution decisions?

A: Operating temperature range should be evaluated based on application requirements. The original SMCJ15CE3/TR13 operates -65°C to 150°C. Most substitutes operate -55°C to 150°C, which is acceptable for applications not requiring extended low-temperature operation. The SMLJ15CA-TP extends to 175°C maximum, suitable for high-temperature environments. The 5.0SMDJ15CA-T7 and SMDJ15CA-T7 from Littelfuse maintain the full -65°C to 150°C range.

Q: What packaging options are available for substitutes?

A: All substitute parts use DO-214AB or SMC surface mount packages, maintaining mechanical compatibility with the original SMCJ15CE3/TR13. Packaging designations vary by manufacturer (SMCJ, SMC, DO-214AB) but refer to the same physical form factor. Tape & Reel (TR) and Cut Tape (CT) options are available depending on the specific part number and manufacturer. Verify packaging format requirements for your assembly process before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all devices, indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute offers the best balance of performance and availability?

A: Selection depends on application requirements. For direct replacement with equivalent performance, SMCJ15CA-13-F (Diodes Incorporated) provides 61.5A current capacity with confirmed REACH compliance and Tape & Reel packaging. For enhanced protection, SMDJ15CA-T7 (Littelfuse) doubles current capacity to 123A while maintaining the -65°C to 150°C temperature range. For maximum protection, 5.0SMDJ15CA-T7 (Littelfuse) provides 205A current capacity with full temperature range compatibility. Inventory availability should be verified with component suppliers for your specific procurement timeline.
