CD214L-T13CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T13CALF 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 13V reverse standoff voltage with a 21.5V maximum clamping voltage and 139.4A peak pulse current capability in a DO-214AB (SMC) package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Substitute Part Grouping Explanation

Substitution for the CD214L-T13CALF is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

Voltage - Reverse Standoff: 13V (exact match required)
Voltage - Clamping (Max) @ Ipp: 21.5V (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Mounting Type: Surface Mount (exact match required)
Type: Zener, Bidirectional (exact match required)

Secondary Consideration:

Current - Peak Pulse (10/1000µs): Minimum 139.4A acceptable; higher ratings permissible
Power - Peak Pulse: Minimum 3000W acceptable; higher ratings permissible
Operating Temperature Range: Minimum -55°C to 150°C acceptable; extended ranges permissible

Substitute parts are grouped into two categories based on peak pulse current capability: direct equivalents (139.4A ±) and higher-capacity alternatives (233A).

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

SMLJ13CA (Bourns Inc.) is the primary direct equivalent. Manufactured by the original supplier, it maintains identical electrical specifications (139.4A peak pulse, 3000W power rating) and operating temperature range. Product status is active with established supply chain availability.

Higher-Capacity Alternatives (Enhanced Protection):

5.0SMDJ13CA (MDE Semiconductor Inc.) and 5.0SMDJ13CA-T7 (Littelfuse Inc.) provide increased peak pulse current (233A) and power dissipation (5000W) while maintaining voltage specifications. These are suitable for applications requiring enhanced transient protection margin. The Littelfuse variant extends operating temperature to -65°C.

Lower-Capacity Alternatives (Cost Optimization):

SMCJ13CA variants (Fairchild Semiconductor, Littelfuse, Micro Commercial Co) reduce peak pulse current to 69.8A and power to 1500W. These are applicable only where circuit transient energy is confirmed below 1500W. Littelfuse SMCJ13CA-HR and SMCJ13CA-HRA extend operating temperature to -65°C. Micro Commercial Co SMCJ13CA-TP extends upper temperature to 175°C.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and MSL Level 1 (unlimited moisture sensitivity). REACH status varies: MDE Semiconductor 5.0SMDJ13CA is REACH Unaffected; Littelfuse and Micro Commercial variants are REACH Unaffected. Bourns SMLJ13CA and Alpha & Omega SMDJ13CA are REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can SMCJ13CA replace CD214L-T13CALF directly?

A: SMCJ13CA matches all voltage and package specifications but provides only 69.8A peak pulse current versus the original 139.4A. Direct replacement is valid only if circuit transient energy does not exceed 1500W. For applications requiring the full 3000W protection capability, use SMLJ13CA or SMDJ13CA instead.

Q: What is the difference between SMLJ13CA and SMDJ13CA?

A: Both provide identical electrical performance (139.4A peak pulse, 3000W power, 13V standoff, 21.5V clamping). SMLJ13CA is manufactured by Bourns Inc. (original supplier); SMDJ13CA is manufactured by Alpha & Omega Semiconductor Inc. Selection depends on supplier availability and procurement requirements.

Q: Are the 5.0SMDJ13CA variants backward compatible?

A: Yes. The 5.0SMDJ13CA and 5.0SMDJ13CA-T7 maintain identical voltage specifications and package form factor. Higher peak pulse current (233A) and power rating (5000W) provide enhanced protection without circuit incompatibility. These are suitable for applications where additional transient margin is beneficial.

Q: Does operating temperature range affect substitution?

A: Operating temperature range does not prevent substitution if the application operates within the substitute part's specified range. Extended-range variants (Littelfuse -65°C to 150°C, Micro Commercial -55°C to 175°C) are compatible with standard-range applications (-55°C to 150°C) and provide additional design margin for extreme-temperature environments.

Q: What packaging options are available?

A: All substitute parts use DO-214AB (SMC) surface-mount package, matching the original CD214L-T13CALF. Packaging format (Tape & Reel or bulk) varies by manufacturer and supplier; electrical and mechanical form factors remain identical.

Q: Is REACH compliance a selection factor?

A: REACH compliance status does not affect electrical substitution. Selection based on REACH status depends on end-market regulatory requirements. REACH Affected parts (Bourns SMLJ13CA, Alpha & Omega SMDJ13CA) require compliance documentation for certain markets; REACH Unaffected parts (MDE, Littelfuse, Micro Commercial variants) do not.
