CD214C-T11CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T11CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., rated for 11V reverse standoff with 18.2V clamping voltage and 82.4A peak pulse current in a surface mount SMC (DO-214AB) package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance characteristics and package compatibility to ensure direct circuit board replacement without design modification.

Substitute Part Grouping Explanation

Substitute parts for the CD214C-T11CALF are classified into two categories based on electrical performance alignment:

Direct Equivalents (1500W Power Rating): Parts maintaining identical peak pulse power of 1500W and peak pulse current of 82.4A to 82.5A. These provide one-to-one functional replacement with no circuit performance variation.

Higher Power Alternatives (3000W Power Rating): Parts with doubled peak pulse power (3000W) and proportionally increased peak pulse current (164.8A to 164.9A). These provide enhanced transient protection capability while maintaining all voltage parameters (11V standoff, 12.2V breakdown, 18.2V clamping).

All substitute candidates maintain the following critical parameters:

Voltage - Reverse Standoff: 11V
Voltage - Breakdown (Min): 12.2V
Voltage - Clamping (Max) @ Ipp: 18.2V
Package: DO-214AB, SMC
Mounting Type: Surface Mount
Type: Zener, Bidirectional
RoHS3 Compliance
MSL Level 1

Engineering Selection Recommendations

For Direct Replacement (1500W Equivalent): SMCJ11CA from Good-Ark Semiconductor provides the most direct functional equivalent with matching 1500W power rating, 82.4A peak current, and identical voltage specifications. This part is in active production status with 17,100 units in stock, ensuring supply continuity. All voltage parameters and operating temperature range align with the original CD214C-T11CALF specification.

For Extended Temperature Range: SMCJ11CA-TP from Micro Commercial Co extends the upper operating temperature to 175°C while maintaining 1500W power rating and identical voltage performance. This option is suitable for applications requiring enhanced thermal margin.

For Enhanced Cold Temperature Performance: SMCJ11CA-HR, SMCJ11CA-HRA, and SMCJ11CA-HRAT7 from Littelfuse extend the lower operating temperature to -65°C. These variants maintain 1500W power rating with marginally increased peak current (82.5A) and are suitable for applications requiring expanded low-temperature operation.

For Higher Transient Protection: SMDJ11CA and SMDJ11CA-T7 provide doubled power dissipation (3000W) with proportionally increased peak pulse current (164.8A to 164.9A). These parts maintain all voltage specifications and are suitable for circuits requiring enhanced transient suppression capability. SMDJ11CA-T7 offers the extended -65°C lower temperature limit.

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and DO-214AB package compatibility for direct PCB replacement.

Frequently Asked Questions (FAQ)

Q: Can SMCJ11CA directly replace CD214C-T11CALF without circuit modification?

A: Yes. SMCJ11CA maintains identical voltage parameters (11V standoff, 12.2V breakdown, 18.2V clamping), peak pulse current (82.4A), power rating (1500W), and DO-214AB package. Direct PCB substitution is possible without design changes.

Q: What is the difference between 1500W and 3000W rated parts?

A: The 1500W parts (SMCJ series) and 3000W parts (SMDJ series) maintain identical voltage specifications but differ in peak pulse current handling. SMDJ parts handle 164.8A to 164.9A versus 82.4A to 82.5A for SMCJ parts. Selection depends on circuit transient energy requirements.

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

A: Yes. All listed substitutes use the DO-214AB (SMC) surface mount package, ensuring mechanical and electrical compatibility with the original CD214C-T11CALF footprint.
