SMCJ5.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ5.0CE3/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 features a 5V reverse standoff voltage, 9.6V maximum clamping voltage, and 156.2A peak pulse current capability in a DO-214AB (SMC) package. The part is actively produced and RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching or compatible electrical characteristics within the 5V protection class, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation ratings. Substitutes accommodate different manufacturer specifications and packaging configurations while maintaining functional equivalence for transient voltage suppression applications.

Substitute Part Grouping Explanation

Substitute parts for the SMCJ5.0CE3/TR13 are classified into two functional groups based on electrical performance and power rating:

Group 1: 1.5kW Power Rating Equivalents These substitutes maintain the same 1500W peak pulse power dissipation as the main part. They share identical reverse standoff voltage (5V), breakdown voltage (6.4V minimum), and clamping voltage specifications (9.2V to 9.6V). Peak pulse current ranges from 156.2A to 171A. These parts are directly interchangeable in applications where 1.5kW transient suppression is specified.

Group 2: 3kW Power Rating Alternatives These substitutes provide double the peak pulse power rating (3000W) with significantly higher peak pulse current capability (326A to 326.1A). They maintain the same voltage protection class (5V standoff, 6.4V breakdown minimum, 9.2V clamping). These parts are suitable for applications requiring enhanced transient energy absorption or where higher current surge events are anticipated.

Critical Substitution Parameters:

• Voltage - Reverse Standoff: 5V (all substitutes)
• Voltage - Breakdown (Min): 6.4V (all substitutes)
• Voltage - Clamping (Max): 9.2V to 9.6V (acceptable range)
• Package / Case: DO-214AB, SMC (all substitutes)
• Mounting Type: Surface Mount (all substitutes)
• Type: Zener, Bidirectional (all substitutes)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (1.5kW Applications): The SMCJ5.0CA (Taiwan Semiconductor Corporation), SMCJ5.0CA-13-F (Diodes Incorporated), and SMCJ5V0CA (Taiwan Semiconductor Corporation) are functionally equivalent to the SMCJ5.0CE3/TR13 within the 1500W power class. All three maintain identical voltage protection specifications (5V standoff, 6.4V breakdown, 9.2V clamping) and are RoHS3 compliant. The SMCJ5.0CA and SMCJ5.0CA-13-F support the full operating temperature range of -55°C to 150°C. Selection among these three should be based on availability, packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), and supplier preference.

For Enhanced Protection (3kW Applications): The SMDJ5.0CA (Alpha & Omega Semiconductor Inc.), SMDJ5.0CA-T7 (Littelfuse Inc.), and SMLJ5.0CA (Bourns Inc.) provide double the peak pulse power rating (3000W) with proportionally higher peak pulse current (326A to 326.1A). These parts are suitable for applications requiring greater transient energy absorption. The SMDJ5.0CA-T7 supports the extended temperature range of -65°C to 150°C, matching the original part specification. All three are RoHS3 compliant.

Compliance Considerations: All substitute parts maintain RoHS3 compliance and REACH unaffected status. Moisture sensitivity level is rated as 1 (Unlimited) across all parts, indicating no special handling requirements. ECCN classification remains EAR99 for all substitutes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ5.0CA be used as a direct replacement for SMCJ5.0CE3/TR13?

A: Yes. The SMCJ5.0CA maintains identical voltage protection specifications (5V standoff, 6.4V breakdown minimum, 9.2V clamping maximum) and equivalent peak pulse power rating (1500W). Both are RoHS3 compliant surface-mount devices in DO-214AB (SMC) packages. The primary difference is the manufacturer (Taiwan Semiconductor Corporation versus Microchip Technology) and operating temperature range (-55°C to 150°C versus -65°C to 150°C). For applications operating above -55°C, this substitution is fully compatible.

Q: What is the difference between 1.5kW and 3kW rated TVS diodes?

A: The power rating reflects the maximum transient energy the device can dissipate during a 10/1000µs pulse event. The 3kW-rated parts (SMDJ5.0CA, SMDJ5.0CA-T7, SMLJ5.0CA) accommodate peak pulse currents of approximately 326A, compared to 156.2A to 171A for 1.5kW-rated parts. Both classes maintain the same voltage protection thresholds (5V standoff, 6.4V breakdown). Selection depends on the anticipated transient current magnitude in the application.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts are available in the DO-214AB (SMC) surface-mount package, ensuring mechanical and electrical compatibility with the original SMCJ5.0CE3/TR13. Packaging formats differ (Tape & Reel versus Cut Tape & Digi-Reel®), but the component footprint and pinout remain identical.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range affects suitability only if the application requires operation below -55°C. The SMCJ5.0CE3/TR13 and SMDJ5.0CA-T7 support -65°C to 150°C. The SMCJ5.0CA, SMCJ5.0CA-13-F, SMDJ5.0CA, and SMLJ5.0CA support -55°C to 150°C. For applications operating within -55°C to 150°C, all substitutes are suitable. For applications requiring -65°C operation, select SMDJ5.0CA-T7 if 3kW rating is acceptable, or verify alternative 1.5kW sources.

Q: What is the significance of clamping voltage variation (9.2V versus 9.6V)?

A: Clamping voltage is the maximum voltage across the TVS diode during transient suppression at peak pulse current. The SMCJ5.0CE3/TR13 specifies 9.6V maximum clamping, while most substitutes specify 9.2V maximum clamping. Both values fall within acceptable protection limits for 5V logic and power supply applications. The 0.4V difference does not affect functional compatibility in standard applications. Selection should be based on circuit-specific voltage margin requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the environmental compliance status of the SMCJ5.0CE3/TR13. Moisture sensitivity level is rated as 1 (Unlimited) for all parts, indicating no special storage or handling requirements.
