SMLJ24CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMLJ24CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 24V reverse standoff voltage and provides clamping at 43V maximum, with a peak pulse current rating of 69.8A and 300W peak pulse power dissipation. The device is housed in a DO-214AB (SMC) package and is supplied in Tape & Reel packaging.

The SMLJ24CE3/TR13 maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical parameters—specifically reverse standoff voltage, breakdown voltage, clamping voltage, and package type—while accounting for variations in peak pulse current and power dissipation capabilities that may affect circuit performance in specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMLJ24CE3/TR13 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Secondary Consideration Parameters:

• Voltage - Clamping (Max) @ Ipp: Acceptable range 38.9V to 43V
• Current - Peak Pulse (10/1000µs): 38.6A to 129A
• Power - Peak Pulse: 1500W to 5000W
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain the core 24V protection voltage class and DO-214AB package footprint. Variations in clamping voltage (38.9V vs. 43V) and peak pulse current ratings reflect different device architectures within the same protection class. Parts with higher current and power ratings provide enhanced transient suppression capability without compromising circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance):

The SMLJ24CE3/TR13 can be directly substituted with parts maintaining identical reverse standoff voltage (24V), breakdown voltage (26.7V minimum), and DO-214AB package configuration. All identified substitute parts meet these core criteria and maintain RoHS3 compliance.

Higher Current/Power Capability Substitutes:

Parts including 5.0SMDJ24CA (129A, 5kW), SMC3K24CAHM3/57 (77.1A, 3kW), SMDJ24CA (77.2A, 3kW), and SMLJ24CA (77.2A, 3kW) provide enhanced transient suppression with higher peak pulse current and power ratings. These devices are suitable for applications requiring greater energy absorption while maintaining the same voltage protection class.

Lower Current/Power Capability Substitutes:

Parts including SMCJ24CA (38.6A, 1.5kW) and SMCJ24CA-13-F (38.6A, 1.5kW) operate at reduced peak pulse current and power levels. These are suitable for applications with lower transient energy requirements.

Compliance and Certification:

All substitute parts are RoHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with standard manufacturing and storage practices. The SMC3K24CAHM3/57 carries AEC-Q101 automotive qualification, suitable for automotive-grade applications. All parts maintain Active product status.

Temperature Range Considerations:

The SMCJ24CA-TP extends the upper operating temperature to 175°C, compared to the standard 150°C maximum of the SMLJ24CE3/TR13. The SMCJ24CA operates at a minimum temperature of -50°C, compared to -55°C for the primary part. All other substitutes maintain the -55°C to 150°C operating range.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SMLJ24CE3/TR13 with a part having a lower clamping voltage (38.9V instead of 43V)?

A: Yes. The clamping voltage difference (38.9V vs. 43V) represents a variation in device architecture within the same 24V protection class. Both values fall within acceptable transient suppression parameters for 24V systems. The lower clamping voltage may provide slightly improved protection characteristics in some applications.

Q: What is the difference between the SMLJ24CE3/TR13 and SMLJ24CA?

A: Both parts share the same base product number (SMLJ24) and manufacturer (Bourns Inc. for SMLJ24CA). The primary differences are clamping voltage (43V vs. 38.9V) and peak pulse current (69.8A vs. 77.2A). The SMLJ24CA provides higher current handling capability at a lower clamping voltage. Both are housed in DO-214AB packages and operate across -55°C to 150°C.

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

A: Most substitute parts are available in Tape & Reel (TR) packaging. The SMCJ24CA variants from MDD do not specify packaging type in the provided data. The SMCJ24CA-13-F is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with your procurement specification before selection.

Q: Can I use the 5.0SMDJ24CA as a direct replacement for high-energy transient applications?

A: Yes. The 5.0SMDJ24CA provides the highest peak pulse current (129A) and power rating (5kW) among all identified substitutes. It maintains the same 24V reverse standoff voltage, 26.7V breakdown voltage, and DO-214AB package configuration. This part is suitable for applications requiring maximum transient energy absorption within the 24V protection class.

Q: What is the significance of the SMC3K24CAHM3/57 carrying AEC-Q101 qualification?

A: AEC-Q101 qualification indicates the part meets automotive-grade reliability and performance standards. This certification is relevant for automotive and harsh-environment applications requiring enhanced quality assurance. The part maintains identical electrical parameters to other 24V TVS diodes in this list while offering automotive-grade validation.

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

A: Selection depends on three primary factors: (1) Required peak pulse current handling—compare your transient energy requirements against the Ipp ratings; (2) Operating temperature range—verify the part's temperature limits match your application environment; (3) Packaging and supply format—confirm Tape & Reel or alternative packaging availability. All listed parts maintain the core 24V protection voltage and DO-214AB footprint, ensuring PCB compatibility.

Q: Is the SMCJ24CA-TP suitable for high-temperature applications?

A: Yes. The SMCJ24CA-TP extends the maximum operating temperature to 175°C (compared to 150°C for most other substitutes). This part is suitable for applications operating in elevated temperature environments while maintaining the same 24V protection voltage and DO-214AB package configuration.
