CD214C-T6.5CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T6.5CALF 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 6.5V reverse standoff voltage with an 11.2V maximum clamping voltage and 133.9A peak pulse current capability in a DO-214AB (SMC) package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214C-T6.5CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Voltage - Breakdown (Min): 7.22V (or 7.2V)
• Current - Peak Pulse (10/1000µs): 133.9A to 134A
• Power - Peak Pulse: 1500W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

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

Category A - Direct Equivalents (1500W, ~134A): Parts with matching voltage specifications, peak pulse current of 133.9A to 134A, and 1500W power rating. These provide direct functional replacement with identical electrical performance.

Category B - Higher Power Alternatives (3000W, ~268A): Parts with matching voltage specifications but doubled peak pulse current (267.9A) and 3000W power rating. These provide enhanced transient protection capability while maintaining voltage compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for 1:1 Replacement):

SMCJ6.5CA (EVVO Semi) and SMCJ6V5CA (Taiwan Semiconductor Corporation) provide direct electrical equivalence to the CD214C-T6.5CALF with matching voltage specifications, peak pulse current, and power dissipation. Both are active products with ROHS3 compliance and MSL 1 rating. SMCJ6.5CA-TP (Micro Commercial Co) offers the same electrical performance with extended operating temperature range (-55°C ~ 175°C) and is supplied in Tape & Reel packaging.

Higher Power Alternatives:

SMDJ6.5CA (Alpha & Omega Semiconductor Inc.) and SMLJ6.5CA-TP (Micro Commercial Co) maintain identical voltage specifications while providing doubled peak pulse current (267.9A) and 3000W power dissipation. These parts are suitable for applications requiring enhanced transient protection margin. SMLJ6.5CA-TP offers extended operating temperature range (-55°C ~ 175°C).

All substitute parts are ROHS3 compliant and carry MSL 1 rating, meeting the compliance requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can SMDJ6.5CA or SMLJ6.5CA-TP be used as direct replacements for CD214C-T6.5CALF?

A: Yes, electrically they are compatible. However, these parts feature doubled peak pulse current (267.9A vs. 133.9A) and 3000W power dissipation (vs. 1500W). They maintain the same voltage specifications (6.5V standoff, 11.2V clamping) and DO-214AB package. Use these only if your circuit design can accommodate the higher current and power ratings, or if enhanced protection margin is desired.

Q: What is the difference between SMCJ6.5CA and SMCJ6.5CA-TP?

A: Both parts are manufactured by Micro Commercial Co with identical electrical specifications. The primary difference is packaging: SMCJ6.5CA is supplied in Cut Tape (CT) & Digi-Reel format, while SMCJ6.5CA-TP is supplied in Tape & Reel (TR). Additionally, SMCJ6.5CA-TP supports an extended operating temperature range of -55°C ~ 175°C compared to the standard -55°C ~ 150°C.

Q: Are all substitute parts available in the same DO-214AB (SMC) package?

A: Yes, all listed substitute parts use the DO-214AB (SMC) surface-mount package, ensuring mechanical and thermal compatibility with the original CD214C-T6.5CALF footprint.

Q: What compliance certifications do the substitute parts carry?

A: All substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level (MSL) 1 rating (unlimited moisture sensitivity). These certifications match the original component's compliance profile.

Q: Why is the CD214C-T6.5CALF obsolete?

A: The original part is listed as obsolete by Bourns Inc. The substitute parts listed are all active products from alternative manufacturers, providing continued design support and production availability.
