CD214L-T30CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T30CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., rated for 30V reverse standoff with 48.4V clamping voltage and 62A peak pulse current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across -55°C to 150°C and is housed in a DO-214AB (SMC) surface mount package, compliant with RoHS3 and REACH regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214L-T30CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff: 30V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 48.4V (exact match required)
• Package / Case: DO-214AB, SMC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Bidirectional Channels: 1 (exact match required)

Substitute parts are grouped into two categories based on peak pulse current and power dissipation:

Direct Equivalents (62A / 3kW): Parts with identical electrical performance to the original specification.

Higher-Performance Alternatives (103A / 5kW): Parts with enhanced current handling and power dissipation capabilities, suitable for applications requiring additional margin or higher transient energy absorption.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Recommended for Pin-Compatible Substitution):

SMLJ30CA (Bourns Inc.) is the primary direct equivalent, maintaining identical electrical specifications and operating temperature range while offering active product status. This part provides continuity with the original manufacturer's design philosophy.

SMDJ30CA (Alpha & Omega Semiconductor Inc.) provides equivalent performance with active status and full RoHS3 compliance. This option is suitable for applications where manufacturer diversification is acceptable.

Extended Temperature Range Option:

SMLJ30CA-TP (Micro Commercial Co) extends the upper operating temperature to 175°C while maintaining all electrical parameters. This option is applicable for designs requiring enhanced thermal margin.

Higher Current Capacity Options:

5.0SMDJ30CA (MDE Semiconductor Inc) and 5.0SMDJ30CA-T7 (Littelfuse Inc.) provide 103A peak pulse current and 5000W power dissipation, offering enhanced transient protection capability. These parts are suitable for applications with higher energy transient events or where additional design margin is required. The 5.0SMDJ30CA-T7 variant extends the lower operating temperature to -65°C.

Lower Current Alternatives (Reduced Margin):

SMCJ30CA (MDD) and SMCJ30CA-TP (Micro Commercial Co) provide 31A peak pulse current and 1500W power dissipation. These parts are suitable only for applications with lower transient energy requirements and should not be used as direct replacements for the original 62A specification without circuit re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can SMCJ30CA or SMCJ30CA-TP be used as direct replacements for CD214L-T30CALF?

A: No. These parts have 31A peak pulse current and 1500W power dissipation, compared to the original 62A and 3000W specification. They are suitable only for applications with lower transient energy requirements and require circuit re-evaluation before substitution.

Q: What is the difference between SMLJ30CA and SMDJ30CA?

A: Both parts meet the original CD214L-T30CALF electrical specification (30V standoff, 48.4V clamp, 62A peak pulse, 3000W power). SMLJ30CA is manufactured by Bourns Inc., while SMDJ30CA is manufactured by Alpha & Omega Semiconductor Inc. Selection depends on supplier availability and procurement preferences.

Q: When should I use the 5.0SMDJ30CA or 5.0SMDJ30CA-T7 variants?

A: These higher-performance parts (103A / 5kW) are appropriate for applications experiencing higher transient energy events or where additional design margin is required. They maintain the same voltage ratings and package as the original part while providing enhanced current handling capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant, maintaining regulatory compliance with the original CD214L-T30CALF specification.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not disqualify substitution if the substitute part's range encompasses the application requirements. SMLJ30CA-TP and SMCJ30CA-TP offer extended upper temperature limits (-55°C ~ 175°C), while 5.0SMDJ30CA-T7 extends the lower limit to -65°C. Standard parts maintain -55°C ~ 150°C or -50°C ~ 150°C ranges.

Q: Is packaging identical across all substitute parts?

A: Yes. All substitute parts use DO-214AB (SMC) surface mount packaging, ensuring mechanical and electrical compatibility with the original CD214L-T30CALF footprint.
