CD214L-T6.0CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T6.0CALF is a 6V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The CD214L-T6.0CALF operates with a 6V reverse standoff voltage, 10.3V maximum clamping voltage, and 291.3A peak pulse current capability in a DO-214AB (SMC) package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214L-T6.0CALF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 6V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 10.3V (exact match required)
• Package / Case: DO-214AB, SMC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Zener, Bidirectional (exact match required)

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

Category A (Full Electrical Equivalents): Parts with 291.3A peak pulse current and 3000W power rating, providing identical performance to the original part.

Category B (Reduced Performance Equivalents): Parts with 145.6–145.7A peak pulse current and 1500W power rating, suitable for applications with lower transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation (Full Electrical Equivalents):

SMLJ6.0CA (Bourns Inc.) is the preferred direct replacement. It maintains identical electrical specifications (291.3A peak pulse current, 3000W power rating) and operating temperature range (-55°C ~ 150°C) as the CD214L-T6.0CALF. Both parts are manufactured by Bourns Inc., ensuring design continuity. SMLJ6.0CA is active and widely available in Tape & Reel packaging.

SMDJ6.0CA (Alpha & Omega Semiconductor Inc.) provides equivalent performance with identical peak pulse current (291.3A) and power rating (3000W). This part is active and suitable for applications requiring full transient energy handling capability.

Secondary Recommendation (Reduced Performance Equivalents):

SMCJ6.0CA-TP (Micro Commercial Co) is suitable for applications with lower transient energy requirements. It provides an extended operating temperature range (-55°C ~ 175°C) compared to the original part, making it advantageous for high-temperature environments. Peak pulse current is reduced to 145.7A with 1500W power rating.

SMCJ6.0CA (MDD), SMCJ6V0CA (Fairchild Semiconductor), and TV15C6V0JB-HF (Comchip Technology) are alternative reduced-performance options with 145.6–145.7A peak pulse current and 1500W power rating. All are active products with ROHS3 compliance.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and EAR99 export classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all recommended substitutes, matching the original part's handling requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a reduced-performance substitute (145.7A) in place of the CD214L-T6.0CALF (291.3A)?

A: Reduced-performance substitutes are suitable only if your application's transient energy requirements do not exceed 1500W peak pulse power. If your circuit experiences transient events exceeding this threshold, use full-equivalent substitutes (SMLJ6.0CA or SMDJ6.0CA) to maintain protection margin.

Q: Are all substitute parts pin-compatible with the CD214L-T6.0CALF?

A: Yes. All substitute parts use the DO-214AB (SMC) package with identical pinout and footprint. Surface-mount placement and reflow parameters remain unchanged.

Q: What is the difference between Tape & Reel and Bulk packaging for these TVS diodes?

A: Tape & Reel packaging is standard for automated assembly lines and high-volume production. Bulk packaging is used for manual assembly or lower-volume applications. Electrical performance is identical; packaging affects only handling and assembly logistics.

Q: Does the extended temperature range of SMCJ6.0CA-TP (-55°C ~ 175°C) provide any advantage?

A: The extended upper temperature limit (175°C vs. 150°C) is beneficial for applications in high-temperature environments or near heat sources. If your design operates within -55°C ~ 150°C, this extended range provides additional thermal margin without performance penalty.

Q: Are there any compliance or certification differences between substitute parts?

A: All recommended substitutes maintain ROHS3 compliance. REACH status varies: Bourns Inc. and Alpha & Omega Semiconductor Inc. parts are REACH Affected; MDD, Micro Commercial Co, Fairchild Semiconductor, and Comchip Technology parts are REACH Unaffected. Verify REACH compliance requirements for your specific application and end market.
