SMBJ58CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ58CE3/TR13 is an active, RoHS3-compliant bidirectional transient voltage suppressor diode manufactured by Microchip Technology. This surface-mount TVS diode is designed for general-purpose transient voltage protection in the 58V voltage class. The need for substitute parts arises from supply chain considerations, manufacturer availability, and circuit design flexibility while maintaining electrical and mechanical compatibility with the original specification.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ58CE3/TR13 are grouped based on the following allowable electrical and mechanical parameters:

Critical Parameters for Substitution:

Voltage - Reverse Standoff (Typ): 58V
Package / Case: DO-214AA, SMB (surface mount)
Type: Zener, Bidirectional
Power - Peak Pulse: 600W

Variable Parameters Permitted Within Substitution:

Voltage - Clamping (Max) @ Ipp: 93.6V to 103V (engineering tolerance)
Current - Peak Pulse (10/1000µs): 5.8A to 6.7A (within thermal dissipation envelope)

Engineering Selection Recommendations

All listed substitute parts meet the active product status and compliance requirements equivalent to the SMBJ58CE3/TR13. Selection among the four parts should be based on:

Manufacturer Availability: Good-Ark Semiconductor (SMBJ58CA) reports 21,927 units in stock; Diodes Incorporated (SMBJ58CA-13-F) reports 38,100 units; STMicroelectronics (SMBJ58CA-TR) reports 17,802 units.
Regulatory Compliance: All parts maintain RoHS3, REACH Unaffected, and EAR99 classifications matching the original specification.
Thermal Performance: The Microchip SMBJ58CE3/TR13 operates to -65°C; substitute parts operate to -55°C minimum. Applications requiring operation below -55°C require the original Microchip part.
Clamping Voltage Tolerance: The original part specifies 103V maximum clamping voltage; substitute parts specify 93.6V maximum. Circuit designs tolerating lower clamping voltages can use any substitute; designs sensitive to clamping voltage must use the Microchip part or application-specific testing.

Frequently Asked Questions (FAQ)

Q: Can I use SMBJ58CA as a direct replacement for SMBJ58CE3/TR13?

A: Electrical substitution is permitted in applications where the circuit tolerates the lower clamping voltage specification (93.6V versus 103V) and operates at temperatures no lower than -55°C. Mechanical compatibility is maintained; both use DO-214AA SMB packaging.

Q: What is the difference between SMBJ58CA and SMBJ58CA-TR?

A: Both parts maintain identical standoff voltage (58V), package (DO-214AA SMB), and power rating (600W). SMBJ58CA-TR (STMicroelectronics) specifies 6.7A peak pulse current versus 6.4A for SMBJ58CA (Good-Ark). Both operate across -55°C to 150°C temperature range with 93.6V maximum clamping voltage.

Q: Does packaging differ between the main part and substitutes?

A: No. All parts use DO-214AA SMB surface-mount packaging. The SMBJ58CE3/TR13 is supplied in Tape & Reel (TR) format; substitute parts are available in equivalent tape and reel or cut tape packaging options, suitable for the same pick-and-place assembly processes.

Q: Why does the Microchip SMBJ58CE3/TR13 have higher clamping voltage (103V)?

A: Clamping voltage variation within the same voltage class represents manufacturing process differences across suppliers. The 103V specification of the Microchip part represents its worst-case clamping performance; the 93.6V specification of substitute parts represents their maximum clamping performance. Circuit selection depends on whether your application requires the additional margin.

Q: Are all parts RoHS3 compliant?

A: Yes. The SMBJ58CE3/TR13 and all listed substitutes are RoHS3 compliant and REACH unaffected, meeting current environmental regulations for electronics manufacturing.

Q: Can I mix suppliers in production?

A: Yes, within engineering constraints. All four parts share identical standoff voltage (58V), breakdown voltage (64.4V minimum), package (DO-214AA SMB), power rating (600W), and compliance status. Substitution across suppliers is electrically and mechanically valid for applications tolerating the specified parameter ranges.
