CD214B-T100CALF Equivalent & Substitute Parts
Part Overview
The CD214B-T100CALF is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 100V reverse standoff voltage, 162V maximum clamping voltage, and 600W peak pulse power rating in a DO-214AA (SMB) package. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation
Substitution eligibility for the CD214B-T100CALF is determined by strict electrical and mechanical parameter matching:
Primary Substitution Criteria:
- Reverse standoff voltage: 100V (±0V tolerance for direct substitution)
- Clamping voltage: 162V maximum @ Ipp
- Peak pulse current: 3.7A minimum
- Peak pulse power: 600W
- Package: DO-214AA (SMB) surface mount
- Bidirectional configuration: 1 channel
- Type: Zener diode
Direct Equivalents maintain all electrical parameters within specification and differ only in manufacturer or packaging format (tape & reel vs. cut tape).
Similar Parts are listed where voltage or current parameters deviate from the original specification. These parts operate within the same application class but require design verification for parameter differences.

Engineering Selection Recommendations
Direct Substitutes (Recommended for Pin-Compatible Replacement):
SMBJ100CA (Good-Ark Semiconductor), SMBJ100CA-TP (Micro Commercial Co), SMBJ100CA-TR (STMicroelectronics), and TV06B101JB-HF (Comchip Technology) are electrically equivalent to the CD214B-T100CALF. All maintain the 100V standoff voltage, 162V clamping voltage, and 600W power rating. These parts are in active production status and carry ROHS3 compliance with MSL 1 rating, ensuring long-term availability and regulatory compliance.
SMBJ100CA-TP offers an extended operating temperature range to 175°C, providing additional thermal margin in high-temperature applications compared to the original 150°C specification.
SMBJ100CA-TR (STMicroelectronics) delivers 3.8A peak pulse current, exceeding the original 3.7A specification while maintaining all other parameters.
Alternative Part (Parameter Deviation):
SMBJ120CA (Meritek) operates at a higher voltage class (120V standoff, 193V clamping) with reduced peak pulse current (3.11A). This part is suitable only for applications where the higher voltage rating is acceptable and the lower current capacity does not compromise circuit protection requirements.
Frequently Asked Questions (FAQ)
Q: Can SMBJ100CA directly replace CD214B-T100CALF without circuit modification?
A: Yes. SMBJ100CA maintains identical electrical specifications: 100V standoff voltage, 162V clamping voltage, 3.7A peak pulse current, and 600W power rating. Both use DO-214AA (SMB) surface-mount packaging. No circuit changes are required.
Q: What is the difference between SMBJ100CA and SMBJ100CA-TP?
A: Both parts are electrically identical with matching voltage and current ratings. The primary difference is operating temperature range: SMBJ100CA-TP extends to 175°C versus 150°C for standard SMBJ100CA. SMBJ100CA-TP is suitable for applications requiring higher thermal performance.
Q: Why is SMBJ120CA listed as a substitute if the voltage is different?
A: SMBJ120CA is classified as a similar part, not a direct equivalent. The 120V standoff and 193V clamping voltages exceed the original specification. This part is listed for reference only and requires design verification to confirm compatibility with the intended circuit protection scheme.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original CD214B-T100CALF compliance status.
Q: What packaging formats are available for substitute parts?
A: Direct equivalents are available in tape & reel (TR) and cut tape (CT) formats. All maintain the DO-214AA (SMB) surface-mount package footprint, ensuring PCB compatibility without layout modifications.
Q: Is the CD214B-T100CALF still available for procurement?
A: The CD214B-T100CALF is classified as obsolete. Active production alternatives such as SMBJ100CA, SMBJ100CA-TP, SMBJ100CA-TR, and TV06B101JB-HF are recommended for new designs and ongoing procurement.
