CD214B-T150CALF Equivalent & Substitute Parts

Part Overview

The CD214B-T150CALF is a 150V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 243V maximum clamping voltage, 2.5A peak pulse current rating, and 600W peak pulse power dissipation capability in a DO-214AA (SMB) package. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214B-T150CALF is determined by strict electrical and mechanical parameter matching within the TVS diode category. The following criteria establish valid equivalence:

Critical Parameters for Substitution:

• Voltage - Reverse Standoff: 150V (nominal)
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Current - Peak Pulse (10/1000µs): 2.5A ± tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Direct Equivalents (SMBJ150CA by MDD): Identical electrical specifications and package configuration. Active product status ensures ongoing availability and manufacturing support.

Similar Equivalents (SMBJ150CA-TP, TV06B151JB-HF): Meet all critical electrical parameters with minor variations in peak pulse current (within acceptable tolerance) and extended or unspecified operating temperature ranges. Packaging format differs (Tape & Reel) but maintains DO-214AA (SMB) footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMBJ150CA (MDD)

The SMBJ150CA by MDD is the preferred direct equivalent. It maintains identical electrical specifications to the CD214B-T150CALF across all critical parameters and is classified as an active product with full manufacturing support. ROHS3 compliance and MSL 1 rating ensure regulatory alignment and handling compatibility with existing supply chain processes. The -50°C to 150°C operating temperature range covers the original part's lower bound specification.

Secondary Recommendations: SMBJ150CA-TP and TV06B151JB-HF

Both parts meet all critical electrical parameters and maintain DO-214AA (SMB) package compatibility. SMBJ150CA-TP by Micro Commercial Co extends the operating temperature range to -55°C to 175°C, providing additional thermal margin. TV06B151JB-HF by Comchip Technology delivers 2.47A peak pulse current, within acceptable tolerance of the 2.5A specification. Both are active products with ROHS3 compliance and MSL 1 rating. Selection between these options depends on packaging format requirements (Tape & Reel availability) and thermal operating envelope needs.

All substitute parts carry ROHS3 compliance and EAR99 ECCN classification, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150CA be used as a direct replacement for CD214B-T150CALF?

A: Yes. SMBJ150CA by MDD is a direct equivalent with identical electrical specifications (150V standoff, 167V breakdown minimum, 243V clamping maximum, 2.5A peak pulse current, 600W peak power) and matching DO-214AA (SMB) package configuration. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between SMBJ150CA and SMBJ150CA-TP?

A: Both parts share identical electrical specifications. The primary difference is packaging format: SMBJ150CA is supplied in standard packaging, while SMBJ150CA-TP is supplied in Tape & Reel (TR) format. SMBJ150CA-TP also specifies an extended operating temperature range of -55°C to 175°C compared to -50°C to 150°C for the standard SMBJ150CA.

Q: Is TV06B151JB-HF compatible with the original CD214B-T150CALF specification?

A: Yes. TV06B151JB-HF meets all critical electrical parameters with a peak pulse current of 2.47A, which is within acceptable tolerance of the 2.5A specification. The DO-214AA (SMB) package footprint is identical, ensuring mechanical compatibility. ROHS3 compliance and MSL 1 rating match the original part.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: Voltage - Reverse Standoff (150V), Voltage - Breakdown minimum (167V), Voltage - Clamping maximum (243V), Current - Peak Pulse (2.5A ± tolerance), Power - Peak Pulse (600W), and Package / Case (DO-214AA, SMB). All substitute parts meet these criteria.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SMBJ150CA, SMBJ150CA-TP, and TV06B151JB-HF are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original CD214B-T150CALF compliance status.

Q: Why is the CD214B-T150CALF marked as obsolete?

A: The CD214B-T150CALF is classified as obsolete by Bourns Inc. Active substitute parts from MDD and other manufacturers provide equivalent functionality with ongoing production support and availability.
