CD214B-T6.0CALF Equivalent & Substitute Parts

Part Overview

The CD214B-T6.0CALF 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 6V reverse standoff voltage, 10.3V maximum clamping voltage, and 58.3A peak pulse current capability in the SMB (DO-214AA) package format. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD214B-T6.0CALF are classified based on electrical parameter matching within defined tolerance bands. The primary substitution criteria are:

Critical Parameters for Substitution:

• Voltage - Reverse Standoff (Typ): 6V nominal
• Voltage - Clamping (Max) @ Ipp: 10.3V maximum
• Current - Peak Pulse (10/1000µs): 58.3A nominal
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Bidirectional Channels: 1
• Type: Zener diode

Direct Equivalents maintain all critical electrical parameters within specification. These parts are interchangeable without circuit redesign.

Similar Alternatives exhibit minor deviations in secondary parameters (such as peak pulse current ±5% or clamping voltage ±0.9V) while maintaining functional compatibility for general-purpose protection applications. These parts require engineering review for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred for Replacement):

SMBJ6.0CA (EVVO Semi) and SMBJ6V0CA (Taiwan Semiconductor Corporation) are direct electrical equivalents with identical voltage and current specifications. Both are active products with ROHS3 compliance and MSL 1 rating. SMBJ6.0CA offers extended lower temperature operation (-65°C vs. -55°C), providing enhanced thermal margin. SMBJ6V0CA maintains the original temperature range of the obsolete CD214B-T6.0CALF.

Compatible Alternatives (Engineering Review Required):

SMBJ6.0CA-TR (STMicroelectronics) exhibits a 4.6% increase in peak pulse current (61A vs. 58.3A) while maintaining clamping voltage specification. This part is suitable for applications where increased transient current handling provides design margin.

TV06B6V0JB-HF (Comchip Technology) provides near-identical electrical performance with 58.25A peak pulse current. Limited inventory availability (845 pcs) may affect procurement feasibility.

Not Recommended for Direct Substitution:

SMBJ6.5CA and SMBJ7.0CA exhibit voltage parameter deviations exceeding acceptable tolerance bands for direct replacement. These parts are suitable only for applications requiring higher voltage suppression thresholds.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and DO-214AA/SMB package compatibility with the original CD214B-T6.0CALF specification.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.0CA directly replace CD214B-T6.0CALF without circuit modification?

A: Yes. SMBJ6.0CA is a direct electrical equivalent with identical reverse standoff voltage (6V), clamping voltage (10.3V), and peak pulse current (58.3A). Both use the DO-214AA/SMB package. No circuit redesign is required.

Q: What is the difference between SMBJ6.0CA and SMBJ6V0CA?

A: Both parts are direct equivalents with identical electrical specifications. The primary difference is operating temperature range: SMBJ6.0CA operates from -65°C to 150°C, while SMBJ6V0CA operates from -55°C to 150°C. SMBJ6.0CA provides extended low-temperature capability.

Q: Why are SMBJ6.5CA and SMBJ7.0CA listed if they cannot directly replace the CD214B-T6.0CALF?

A: These parts are included for reference in applications where voltage suppression requirements differ from the original design. SMBJ6.5CA (6.5V standoff) and SMBJ7.0CA (7V standoff) are suitable only for circuits designed to tolerate higher clamping voltages.

Q: Is the SMBJ6.0CA-TR (STMicroelectronics) suitable for the same application?

A: SMBJ6.0CA-TR is functionally compatible with a 4.6% higher peak pulse current rating (61A vs. 58.3A). This increased current capacity provides additional transient protection margin and is suitable for most applications. Verify that the circuit design does not depend on the lower current specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity) rating, matching the environmental and regulatory status of the original CD214B-T6.0CALF.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in DO-214AA/SMB surface-mount package format. Packaging options vary by manufacturer: SMBJ6.0CA is available in Cut Tape (CT) and Digi-Reel format; SMBJ6V0CA and TV06B6V0JB-HF are supplied in Tape & Reel (TR) format; SMBJ6.0CA-TR is available in Cut Tape and Digi-Reel format.
