Substitute Part Grouping Explanation

Substitute components for the 5SMC43A TR13 must satisfy the following electrical and mechanical criteria:

• Voltage - Reverse Standoff: 43V (nominal)
• Voltage - Clamping (Max) @ Ipp: 69.4V
• Current - Peak Pulse (10/1000µs): 72.1A
• Power - Peak Pulse: 5000W
• Package / Case: DO-214AB, SMC (surface mount)
• Type: Unidirectional Zener TVS diode
• Unidirectional Channels: 1

The 5.0SMDJ43A/TR13 manufactured by YAGEO meets all specified electrical parameters and package requirements, making it a direct functional equivalent. Both components share identical voltage ratings, current handling capacity, and power dissipation specifications within the same physical package footprint.

Parameter Comparison

*The 5.0SMDJ43A/TR13 has a minimum operating temperature of -55°C versus -65°C for the 5SMC43A TR13. Applications requiring operation below -55°C require evaluation against specific system requirements.

Engineering Selection Recommendations

The 5.0SMDJ43A/TR13 is a qualified substitute for the 5SMC43A TR13 based on electrical parameter equivalence and identical package specifications. The substitute part is currently in Active production status with 3799 units available in inventory, providing supply continuity for the discontinued 5SMC43A TR13.

The 5.0SMDJ43A/TR13 carries ROHS3 compliance certification and Moisture Sensitivity Level (MSL) 1 rating, indicating compatibility with standard manufacturing and storage conditions. The ECCN classification (EAR99) and HTSUS code (8541.10.0080) are provided for regulatory and customs documentation purposes.

Selection between these components should be based on application temperature range requirements. Applications operating at temperatures below -55°C must retain the original 5SMC43A TR13 or identify alternative components with extended low-temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can the 5.0SMDJ43A/TR13 be used as a direct replacement for the 5SMC43A TR13?

A: Yes, the 5.0SMDJ43A/TR13 is electrically and mechanically equivalent for applications operating within the -55°C to 150°C temperature range. All voltage ratings, current handling, power dissipation, and package specifications are identical.

Q: What is the difference in operating temperature range between these parts?

A: The 5SMC43A TR13 operates from -65°C to 150°C, while the 5.0SMDJ43A/TR13 operates from -55°C to 150°C. The substitute part has a 10°C higher minimum operating temperature. Applications requiring operation below -55°C must use the original part or identify alternative components.

Q: Are the packages physically identical?
