CD214C-T58CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T58CALF is a 58V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., rated for 93.6V clamping voltage and 16A peak pulse current in a surface mount SMC (DO-214AB) package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

TVS diodes in this voltage class are used for transient overvoltage protection in general-purpose applications. The 58V reverse standoff voltage with 93.6V maximum clamping voltage defines the protection window for this device category.

Substitute Part Grouping Explanation

Substitute parts for the CD214C-T58CALF are classified into two categories based on electrical parameter compatibility:

Direct Substitutes (Electrical Equivalents) Parts that maintain identical or near-identical electrical specifications: 58V reverse standoff, 64.4V minimum breakdown, 93.6V maximum clamping voltage, and 16A peak pulse current within the 1500W power dissipation envelope. These parts are pin-compatible and functionally interchangeable in the same circuit application.

Similar Substitutes (Higher Current Rating) Parts that exceed the peak pulse current specification (54.6A instead of 16A) while maintaining the same voltage parameters and package. These provide enhanced transient protection capability and are suitable for applications requiring higher surge current handling. The 5kW power rating represents a significant increase over the 1500W baseline.

All substitute parts maintain the DO-214AB (SMC) surface mount package, single bidirectional channel configuration, and ROHS3 compliance required for modern electronics manufacturing.

Engineering Selection Recommendations

For Direct Replacement (1:1 Electrical Equivalence)

SMCJ58CA (EVVO Semi) and SMCJ58CA-13-F (Diodes Incorporated) are the primary direct substitutes, maintaining identical 16A peak pulse current and 1500W power dissipation. Both manufacturers are active in production with established supply chains. SMCJ58CA-TP (Micro Commercial Co) extends the upper operating temperature to 175°C, providing additional thermal margin for applications in elevated ambient conditions.

The Littelfuse SMCJ-HR series (SMCJ58CA-HR, SMCJ58CA-HRA, SMCJ58CA-HRAT7) offers extended lower temperature operation to -65°C and maintains electrical equivalence. These variants are suitable for applications requiring wider temperature range coverage.

For Enhanced Protection (Higher Current Rating)

The 5.0SMDJ58CA (HY Electronic) and 5.0SMLJ58CA-TP (Micro Commercial Co) provide 54.6A peak pulse current and 5000W power dissipation while maintaining the same 58V/93.6V voltage parameters. These parts are suitable for applications experiencing higher transient surge currents or requiring greater energy absorption capability. The extended temperature range of 5.0SMLJ58CA-TP (-55 to 175°C) aligns with modern industrial and automotive requirements.

All recommended substitutes maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ58CA directly replace CD214C-T58CALF without circuit modification?

A: Yes. SMCJ58CA maintains identical voltage parameters (58V standoff, 93.6V clamping) and equivalent peak pulse current (16.1A vs. 16A). The DO-214AB package is identical. No circuit changes are required.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes (SMCJ58CA series) maintain the 16A peak pulse current rating and 1500W power dissipation of the original part. Similar substitutes (5.0SMDJ58CA, 5.0SMLJ58CA-TP) provide 54.6A peak pulse current and 5000W power dissipation. Use similar substitutes only if your application requires higher transient current handling.

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

A: Yes. All listed substitutes use the DO-214AB (SMC) surface mount package, maintaining identical PCB footprint and reflow soldering compatibility.

Q: Which substitute offers the widest operating temperature range?

A: SMCJ58CA-TP and 5.0SMLJ58CA-TP both operate from -55°C to 175°C, providing the widest temperature envelope. The Littelfuse SMCJ-HR variants extend the lower limit to -65°C but maintain the 150°C upper limit.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.

Q: Can I use a higher current-rated part (5.0SMDJ58CA) in place of the original 16A part?

A: Yes. The 5.0SMDJ58CA maintains identical voltage specifications and provides enhanced current handling. This is a conservative substitution that increases protection margin. Verify that your PCB layout and thermal management can accommodate the higher power dissipation (5kW vs. 1500W).
