CD214B-T130CALF Equivalent & Substitute Parts

Part Overview

The CD214B-T130CALF 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 130V reverse standoff voltage with a 209V maximum clamping voltage and 2.9A peak pulse current capability in the DO-214AA (SMB) package format. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD214B-T130CALF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): 2.9A nominal or within 0.03A tolerance
• Package / Case: DO-214AA (SMB)
• Type: Zener, Bidirectional, single channel
• Operating Temperature range: -55°C ~ 150°C minimum
• RoHS3 Compliance and MSL 1 rating

The substitute parts identified below meet these electrical and mechanical specifications, enabling direct replacement in circuit designs without modification to PCB layouts or thermal management considerations.

Parameter Comparison

Engineering Selection Recommendations

SMBJ130CA (Meritek) is the primary direct substitute for the CD214B-T130CALF. This part maintains electrical equivalence with a peak pulse current of 2.87A, which falls within acceptable tolerance of the original 2.9A specification. The SMBJ130CA carries active product status with 49,500 units in stock, ensuring supply chain continuity. Full RoHS3 compliance and MSL 1 rating match the original component specifications.

TV06B131JB-HF (Comchip Technology) serves as an alternative substitute with identical voltage and power ratings. This part is also actively manufactured with 819 units available. RoHS3 compliance and MSL 1 rating are confirmed. The operating temperature range is not specified in available documentation; this parameter should be confirmed against application requirements if thermal extremes are anticipated.

Both substitute parts are surface-mount compatible with existing PCB designs and require no circuit modifications for implementation.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130CA directly replace CD214B-T130CALF without PCB modification?

A: Yes. Both components use the DO-214AA (SMB) package with identical pinout and footprint. No PCB layout changes are required.

Q: What is the significance of the 2.87A vs. 2.9A peak pulse current difference?

A: The 0.03A difference represents a 1% variance within normal manufacturing tolerances for TVS diodes. Both values satisfy the 600W peak pulse power specification and are functionally equivalent for general-purpose overvoltage protection applications.

Q: Are there compliance differences between the substitute parts?

A: Both SMBJ130CA and TV06B131JB-HF maintain ROHS3 compliance and MSL 1 rating. The SMBJ130CA explicitly confirms REACH Unaffected status, while the original CD214B-T130CALF is REACH Affected. Verify REACH compliance requirements for your specific application and supply chain.

Q: Why is the CD214B-T130CALF marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. Active substitutes with identical electrical specifications are available from alternative manufacturers to support existing designs.

Q: Should operating temperature range be a selection criterion?

A: Yes, if your application operates at temperature extremes. The SMBJ130CA specifies -55°C ~ 150°C matching the original part. The TV06B131JB-HF does not provide operating temperature documentation; confirm this parameter with the manufacturer if thermal extremes are present in your design environment.

Q: What packaging format is used for production quantities?

A: SMBJ130CA is supplied in Tape & Reel (TR) format, standard for surface-mount production assembly. TV06B131JB-HF is also available in Tape & Reel format. Confirm packaging requirements with your assembly partner.
