CD214C-T54CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T54CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., classified as a unidirectional Zener-type device in the DO-214AB (SMC) surface mount package. This component is rated for 54V reverse standoff voltage with an 87.1V maximum clamping voltage and 17.2A peak pulse current capability at 1500W peak pulse power. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD214C-T54CALF are classified into two categories based on electrical parameter alignment:

Direct Substitutes (Electrical Equivalents): Parts meeting all critical electrical parameters within acceptable tolerance:

• Voltage - Reverse Standoff: 54V
• Voltage - Clamping (Max) @ Ipp: 87.1V
• Voltage - Breakdown (Min): 60V
• Current - Peak Pulse (10/1000µs): 17.2A ± tolerance
• Power - Peak Pulse: 1500W (1.5kW)
• Package / Case: DO-214AB (SMC)
• Operating Temperature Range: -55°C to 150°C minimum

Similar Substitutes (Higher Performance): Parts with identical voltage ratings and package but enhanced current handling and power dissipation capabilities. These provide superior transient protection margins while maintaining full backward compatibility in circuit topology.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents: SMCJ54CA (Meritek), SMCJ54CA-HR (Littelfuse), SMCJ54CA-HRA (Littelfuse), SMCJ54CA-HRAT7 (Littelfuse), and SMCJ54CA-TP (Micro Commercial Co) are functionally equivalent to the CD214C-T54CALF. All maintain identical voltage ratings (54V standoff, 87.1V clamping), equivalent peak pulse current specifications (17.2A–17.3A), and 1500W power dissipation. All substitute options are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory alignment.

Enhanced Performance Alternatives: SMDJ54CA (Alpha & Omega Semiconductor Inc.), 5.0SMDJ54CA (MDE Semiconductor Inc.), and 5.0SMLJ54CA-TP (Micro Commercial Co) provide superior transient suppression capability with doubled or tripled peak pulse current (34.5A–57.5A) and power dissipation (3000W–5000W) while maintaining identical voltage specifications and DO-214AB package compatibility. These options are suitable for applications requiring enhanced protection margins or higher transient energy absorption.

Temperature Considerations: SMCJ54CA-TP and 5.0SMLJ54CA-TP extend the upper operating temperature to 175°C, compared to the original 150°C specification. SMCJ54CA-HR, SMCJ54CA-HRA, and SMCJ54CA-HRAT7 extend the lower operating temperature to -65°C. Selection should align with specific thermal environment requirements.

Frequently Asked Questions (FAQ)

Q: Can SMCJ54CA directly replace CD214C-T54CALF without circuit modification?

A: Yes. SMCJ54CA matches all critical electrical parameters: 54V reverse standoff, 87.1V clamping voltage, 17.22A peak pulse current, and 1500W power dissipation. The DO-214AB (SMC) package is identical. No circuit redesign is required.

Q: What is the difference between direct equivalents and similar substitutes?

A: Direct equivalents (SMCJ54CA series) maintain the original 1500W power rating and 17.2A–17.3A current specification. Similar substitutes (SMDJ54CA, 5.0SMDJ54CA, 5.0SMLJ54CA-TP) provide higher current handling (34.5A–57.5A) and power dissipation (3000W–5000W) while preserving voltage ratings. Both categories are electrically compatible; selection depends on transient protection margin requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original CD214C-T54CALF specification.

Q: Does packaging differ between substitutes?

A: All substitute parts use the DO-214AB (SMC) surface mount package, identical to the original. Packaging variants (Tape & Reel, Cut Tape) refer to supply format only and do not affect electrical or mechanical compatibility.

Q: Which substitute offers the widest operating temperature range?

A: SMCJ54CA-TP and 5.0SMLJ54CA-TP both support -55°C to 175°C, extending the upper limit by 25°C compared to the original -55°C to 150°C specification.

Q: Can higher-power substitutes (SMDJ54CA, 5.0SMDJ54CA) be used in place of the original?

A: Yes. Higher-power variants are fully backward compatible. They provide enhanced transient suppression capability without requiring circuit modifications. The increased current and power ratings offer additional protection margin in the same package footprint.
