CD214C-T60CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T60CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface mount applications. This bidirectional Zener diode operates with a 60V reverse standoff voltage and provides 96.8V clamping at 15.5A peak pulse current. The component is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain electrical and mechanical compatibility for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution for the CD214C-T60CALF is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

Voltage - Reverse Standoff: 60V (exact match required)
Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
Current - Peak Pulse: 15.5A (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Bidirectional Channels: 1 (exact match required)
Type: Zener (exact match required)

Direct Equivalents maintain all electrical parameters and identical peak pulse current ratings. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Parts share the same voltage ratings and package but feature enhanced peak pulse current capability (51.7A) and higher power dissipation (5000W). These parts are electrically compatible but provide superior transient protection margins. Selection depends on application requirements for additional surge capacity.

Engineering Selection Recommendations

Direct Equivalent Selection (Identical Electrical Performance):

SMCJ60CA from Fairchild Semiconductor is the primary direct equivalent. This part maintains all electrical specifications of the CD214C-T60CALF with identical 15.5A peak pulse current and 1500W power dissipation. The part is in active production status with substantial inventory availability (15,602 units), ensuring supply chain continuity.

Extended Temperature Range Options:

SMCJ60CA-HR, SMCJ60CA-HRA, and SMCJ60CA-HRAT7 from Littelfuse Inc. provide identical electrical performance with extended lower operating temperature limit (-65°C versus -55°C). These variants are suitable for applications requiring enhanced cold-temperature performance while maintaining all other electrical parameters.

Enhanced Surge Protection Options:

5.0SMDJ60CA from MDE Semiconductor Inc. and 5.0SMDJ60CA-T7 from Littelfuse Inc. provide the same voltage ratings but with significantly higher peak pulse current (51.7A) and power dissipation (5000W). These parts are electrically compatible and pin-compatible in the DO-214AB package. Selection of these enhanced-rating parts is appropriate for applications requiring additional transient protection margin or where surge events exceed 15.5A specifications.

Compliance Considerations:

All substitute parts listed maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, consistent with the original CD214C-T60CALF specifications. ECCN and HTSUS classifications remain unchanged across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ60CA directly replace CD214C-T60CALF without circuit modification?

A: Yes. SMCJ60CA maintains identical electrical parameters: 60V reverse standoff, 96.8V clamping voltage, and 15.5A peak pulse current. The DO-214AB package is mechanically identical, enabling direct PCB substitution.

Q: What is the difference between 15.5A and 51.7A peak pulse current variants?

A: The 15.5A variants (SMCJ60CA series) are rated for standard transient protection applications. The 51.7A variants (5.0SMDJ60CA series) provide enhanced surge capacity and are suitable for applications experiencing higher-magnitude transient events or requiring additional protection margin. Both maintain the same 60V/96.8V voltage specifications.

Q: Are Littelfuse SMCJ60CA-HR variants suitable for all applications?

A: SMCJ60CA-HR, SMCJ60CA-HRA, and SMCJ60CA-HRAT7 are suitable for applications requiring extended lower temperature operation (-65°C minimum versus -55°C). All other electrical and mechanical specifications remain identical to the standard SMCJ60CA.

Q: Do all substitute parts use the same DO-214AB package?

A: Yes. All listed substitute parts use the DO-214AB (SMC) surface mount package, ensuring mechanical compatibility and identical PCB footprint with the original CD214C-T60CALF.

Q: What is the inventory status for substitute parts?

A: SMCJ60CA (Fairchild) has the highest availability at 15,602 units. Enhanced-rating 5.0SMDJ60CA variants have 4,400 units (MDE) and 1,196 units (Littelfuse). Littelfuse HR variants range from 991 to 1,122 units. Vishay TransZorb variants have 674 to 736 units available.
