CD214C-T110CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T110CALF 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 110V reverse standoff voltage with 177V maximum clamping voltage and 8.4A peak pulse current capability in a DO-214AB (SMC) package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the CD214C-T110CALF is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 110V
Voltage - Breakdown (Min): 122V
Voltage - Clamping (Max) @ Ipp: 177V
Package / Case: DO-214AB, SMC
Bidirectional Channels: 1
Type: Zener
Operating Temperature Range: -55°C minimum to 150°C maximum

Substitute parts are grouped into two categories:

Direct Substitutes maintain identical electrical specifications and peak pulse current ratings (8.4A to 8.5A range), ensuring drop-in compatibility with the original design.

Similar Substitutes maintain all voltage parameters and package specifications but feature higher peak pulse current ratings (17A to 28.3A) and correspondingly higher power dissipation capabilities (3000W to 5000W). These parts provide enhanced protection margins and are electrically compatible for applications where the original current rating is not a limiting constraint.

Engineering Selection Recommendations

Primary Recommendation: SMCJ110CA (Fairchild Semiconductor)

The SMCJ110CA provides exact electrical and thermal specifications matching the CD214C-T110CALF with active product status. This part is ROHS3 compliant and maintains identical operating temperature range (-55°C ~ 150°C). With 3311 units in stock, procurement availability is established.

Secondary Recommendations: Littelfuse SMCJ110CA-HR, SMCJ110CA-HRA, SMCJ110CA-HRAT7

These Littelfuse variants offer marginally higher peak pulse current (8.5A vs 8.4A) within the same 1500W power envelope and identical clamping voltage. Extended lower operating temperature limit (-65°C vs -55°C) provides additional thermal margin. All three variants are ROHS3 compliant with active status and adequate inventory levels (731-995 units).

Tertiary Recommendation: SMCJ110CA-M3/57T (Vishay General Semiconductor)

The Vishay TransZorb® series part maintains exact specifications with 8.5A peak pulse current and matches the original -55°C ~ 150°C operating range. ROHS3 compliant with 809 units available.

Enhanced Protection Options: SMDJ110CA, 5.0SMDJ110CA, 5.0SMLJ110CA-TP

These parts maintain all voltage specifications and package form factor while providing higher current handling (17A to 28.3A) and power dissipation (3000W to 5000W). Selection of these parts is appropriate when circuit design permits higher transient energy absorption or when enhanced protection margins are required. All are ROHS3 compliant with active status.

Frequently Asked Questions (FAQ)

Q: Can I use SMDJ110CA or 5.0SMDJ110CA as direct replacements for CD214C-T110CALF?

A: Yes. These parts maintain identical voltage specifications (110V reverse standoff, 122V breakdown minimum, 177V clamping maximum) and package form factor (DO-214AB, SMC). The higher current ratings (17A and 28.3A respectively) do not prevent substitution; they provide additional transient energy handling capability. Verify that your circuit design does not depend on the original 8.4A current limitation.

Q: What is the difference between SMCJ110CA-HR, SMCJ110CA-HRA, and SMCJ110CA-HRAT7?

A: All three Littelfuse variants share identical electrical specifications (110V standoff, 177V clamping, 8.5A peak pulse, 1500W power). The suffix designations indicate packaging and tape configuration differences. SMCJ110CA-HRAT7 specifies tape
