CD214L-T58CALF Equivalent & Substitute Parts
Part Overview
The CD214L-T58CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface mount applications. This component features a 58V reverse standoff voltage with a 93.6V maximum clamping voltage and 32A peak pulse current capability in a DO-214AB (SMC) package. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
Substitution of the CD214L-T58CALF is determined by strict equivalence across the following critical parameters:
- Voltage Rating: Reverse standoff voltage of 58V, breakdown voltage minimum of 64.4V, and clamping voltage maximum of 93.6V
- Package Type: DO-214AB (SMC) surface mount package
- Bidirectionality: Single-channel bidirectional configuration
- Zener Type: Zener diode classification
- RoHS Compliance: ROHS3 compliant status
- Moisture Sensitivity: MSL 1 rating
Substitute parts are grouped into two categories based on electrical performance alignment:
Direct Equivalents maintain identical voltage specifications and peak pulse current ratings of 32A at 3000W peak pulse power.
Functional Equivalents maintain identical voltage specifications but vary in peak pulse current capability and power dissipation, suitable for applications where the original current rating is not a limiting constraint.

Engineering Selection Recommendations
SMLJ58CA (Bourns Inc.) is the primary direct equivalent, maintaining identical electrical specifications and power ratings while offering active product status. This part is available in Cut Tape and Digi-Reel packaging formats with substantial inventory availability.
SMDJ58CA (Alpha & Omega Semiconductor Inc.) provides direct electrical equivalence with matching 32A peak pulse current and 3000W power dissipation. This part maintains active status and offers the highest inventory availability among direct equivalents.
5.0SMDJ58CA (HY Electronic) is suitable for applications requiring enhanced current handling capability (54.6A) and power dissipation (5kW). This part extends the operating temperature range to -65°C and is appropriate for telecom applications where higher transient energy absorption is required.
SMCJ58CA and SMCJ58CA-TP (EVVO Semi and Micro Commercial Co respectively) are functional equivalents with reduced peak pulse current (16.1A) and power dissipation (1.5kW). These parts are suitable for lower-energy transient protection applications. SMCJ58CA-TP offers an extended operating temperature range to 175°C.
All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.
Frequently Asked Questions (FAQ)
Q: Can SMCJ58CA replace CD214L-T58CALF in all applications?
A: SMCJ58CA maintains identical voltage specifications but provides reduced peak pulse current (16.1A versus 32A) and power dissipation (1.5kW versus 3kW). Substitution is valid only for applications where transient energy does not exceed 1.5kW. Circuit analysis is required to confirm compatibility.
Q: What is the difference between SMLJ58CA and SMDJ58CA?
A: Both parts provide direct electrical equivalence to the CD214L-T58CALF with 32A peak pulse current and 3000W power dissipation. The primary difference is manufacturer: SMLJ58CA is manufactured by Bourns Inc., while SMDJ58CA is manufactured by Alpha & Omega Semiconductor Inc. Both maintain identical voltage ratings and package specifications.
Q: Is 5.0SMDJ58CA a direct replacement?
A: 5.0SMDJ58CA maintains identical voltage specifications but provides enhanced current handling (54.6A versus 32A) and power dissipation (5kW versus 3kW). This part is suitable as a replacement and offers superior transient protection capability. The extended temperature range (-65°C to 150°C) provides additional operational margin.
Q: Are all substitute parts available in DO-214AB (SMC) package?
A: All listed substitute parts are available in DO-214AB (SMC) surface mount package. Packaging formats vary by manufacturer and supplier: some are supplied in Cut Tape and Digi-Reel formats, while others are supplied in Tape & Reel format. Verify packaging availability with your supplier for procurement requirements.
Q: Do all substitute parts meet RoHS3 compliance?
A: All listed substitute parts are ROHS3 compliant. Moisture sensitivity level is MSL 1 (Unlimited) for all parts except SMDJ58CA, where MSL is not specified. Confirm MSL requirements with your manufacturing process before final selection.
Q: What is the temperature operating range difference between substitutes?
A: Most substitute parts operate within -55°C to 150°C (TJ). SMCJ58CA-TP extends to 175°C, and 5.0SMDJ58CA extends the lower limit to -65°C. Select based on your application's thermal requirements.
