SMLJ64CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMLJ64CE3/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 64V reverse standoff voltage and provides clamping at 114V maximum, with a peak pulse current rating of 26.4A and 300W peak pulse power dissipation. The device is housed in a DO-214AB (SMC) package and is supplied in Tape & Reel packaging.

The SMLJ64CE3/TR13 maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical characteristics within the 64V voltage class, compatible surface-mount packaging, and general-purpose TVS diode applications. Substitutes may vary in peak pulse current ratings, clamping voltage, and power dissipation capabilities while maintaining the same reverse standoff voltage and breakdown specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ64CE3/TR13 are qualified based on the following critical parameters:

Voltage Class Matching: All substitute parts maintain the same 64V reverse standoff voltage and 71.1V minimum breakdown voltage, ensuring compatibility with the protected circuit voltage levels.

Package Compatibility: All substitutes use the DO-214AB (SMC) surface-mount package, maintaining identical PCB footprint and assembly process compatibility.

Bidirectional Configuration: All substitutes are single-channel bidirectional Zener TVS diodes, providing equivalent transient protection polarity.

Clamping Voltage Range: Substitute parts exhibit clamping voltages between 103V and 114V at peak pulse current, remaining within acceptable transient suppression limits for the 64V voltage class.

Peak Pulse Current and Power Dissipation: Substitute parts vary in peak pulse current ratings (14.56A to 48.6A) and power dissipation (1.5kW to 5kW), allowing selection based on specific circuit transient energy requirements.

Compliance and Status: All substitute parts maintain Active product status, ROHS3 compliance, and MSL 1 rating, ensuring regulatory and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

SMDJ64CA, SMDJ64CA-T7, and SMLJ64CA are direct functional equivalents to the SMLJ64CE3/TR13, offering identical 64V reverse standoff voltage, 71.1V breakdown voltage, and 103V clamping voltage. These parts provide 29.1A to 29.2A peak pulse current with 3000W power dissipation, suitable for applications requiring moderate transient energy absorption. All maintain Active product status and ROHS3 compliance. SMDJ64CA-T7 extends the lower operating temperature limit to -65°C, providing enhanced performance in cold environments.

Higher Power Capability Substitute:

5.0SMDJ64CA from MDE Semiconductor Inc provides the highest peak pulse current (48.6A) and power dissipation (5000W) within the 64V voltage class. This part is selected for applications with severe transient energy requirements while maintaining identical voltage specifications and DO-214AB packaging.

Lower Power Alternatives:

SMCJ64CA, SMCJ64CA-13-F, and SMCJ64CA-TP offer reduced peak pulse current (14.56A to 14.6A) and power dissipation (1500W), suitable for applications with lower transient energy levels. SMCJ64CA-TP extends the upper operating temperature to 175°C, accommodating high-temperature circuit environments.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and regulatory requirements. Selection should be based on specific circuit transient energy requirements and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can SMCJ64CA be used as a direct replacement for SMLJ64CE3/TR13?

A: SMCJ64CA is electrically compatible within the 64V voltage class, sharing identical reverse standoff voltage (64V), breakdown voltage (71.1V), and clamping voltage (103V). However, it provides lower peak pulse current (14.56A versus 26.4A) and power dissipation (1500W versus 300W). Selection depends on whether the circuit transient energy is within the lower power rating.

Q: What is the difference between SMDJ64CA and SMCJ64CA?

A: Both parts maintain identical voltage specifications (64V standoff, 71.1V breakdown, 103V clamping) and DO-214AB packaging. SMDJ64CA provides higher peak pulse current (29.2A) and power dissipation (3000W) compared to SMCJ64CA (14.56A, 1500W). Selection is based on circuit transient energy requirements.

Q: Is the 5.0SMDJ64CA suitable for all applications using SMLJ64CE3/TR13?

A: The 5.0SMDJ64CA maintains identical voltage specifications and packaging but provides significantly higher peak pulse current (48.6A) and power dissipation (5000W). It is suitable for applications with severe transient conditions. Verify that the circuit design accommodates the higher power capability without introducing unintended effects.

Q: Does operating temperature range affect part selection?

A: Operating temperature ranges vary among substitutes. SMDJ64CA-T7 operates from -65°C to 150°C, while SMCJ64CA-TP extends to 175°C. Select based on specific circuit operating conditions. The SMLJ64CE3/TR13 operates from -55°C to 150°C.

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

A: Packaging formats vary. SMLJ64CE3/TR13, 5.0SMDJ64CA, SMCJ64CA-13-F, SMCJ64CA-TP, and SMDJ64CA-T7 are specified with Tape & Reel packaging. SMCJ64CA and SMDJ64CA do not specify packaging format in the provided data. Verify packaging availability with the supplier for production requirements.

Q: What is the significance of clamping voltage differences (114V versus 103V)?

A: The SMLJ64CE3/TR13 clamps at 114V maximum, while most substitutes clamp at 103V. Both values remain within acceptable transient suppression limits for 64V voltage class protection. The lower clamping voltage of substitutes provides slightly tighter transient voltage control. Verify circuit tolerance for the specific clamping voltage.

Q: Can SMLJ64CA from Bourns be used interchangeably with SMLJ64CE3/TR13 from Microchip?

A: SMLJ64CA maintains identical electrical specifications (64V standoff, 71.1V breakdown, 103V clamping, 29.2A peak pulse current, 3000W power dissipation) and DO-214AB packaging. Both are ROHS3 compliant with MSL 1 rating. The primary difference is the manufacturer. Electrical and mechanical compatibility is confirmed.

Q: How do I determine which substitute is appropriate for my application?

A: Selection is based on three primary criteria: (1) Peak pulse current and power dissipation requirements—compare circuit transient energy to part ratings; (2) Operating temperature range—verify the substitute operates within circuit temperature limits; (3) Clamping voltage tolerance—confirm the circuit accepts the specified clamping voltage. All substitutes maintain the 64V voltage class and DO-214AB package compatibility.
