CD214B-T13ALF Equivalent & Substitute Parts

Part Overview

The CD214B-T13ALF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface mount applications. This component features a 13V reverse standoff voltage with a 21.5V maximum clamping voltage and 27.9A peak pulse current capability in the DO-214AA (SMB) package format. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214B-T13ALF is determined by strict alignment of the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Breakdown (Min): 14.4V
• Voltage - Clamping (Max) @ Ipp: 21.5V
• Current - Peak Pulse (10/1000µs): 27.9A ± tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Unidirectional Channels: 1
• Mounting Type: Surface Mount

Acceptable Variation Ranges:

• Peak pulse current within ±2A of 27.9A specification
• Operating temperature range may extend beyond original specification
• RoHS and REACH compliance status may differ

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all mandatory electrical parameters with identical or superior specifications and active product status.

Similar Substitutes: Parts with minor deviations in peak pulse current (within ±2A) or operating temperature range, suitable for applications where the original specification provides design margin.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMBJ13A (MDD)

The SMBJ13A from MDD provides direct electrical equivalence with all critical parameters matching the CD214B-T13ALF specification. This part is in active production status with high inventory availability (56,400 pcs), ensuring long-term supply continuity. ROHS3 compliance and MSL 1 rating maintain environmental and handling compatibility with the original design.

Secondary Recommendation: SMBJ13A-TR (STMicroelectronics)

The SMBJ13A-TR from STMicroelectronics meets all mandatory electrical parameters with peak pulse current of 29A, providing additional design margin. Active product status and ROHS3 compliance support production continuity. Operating temperature range matches the original specification (-55°C ~ 150°C).

Tertiary Recommendation: SMBJ13A-TP (Micro Commercial Co)

The SMBJ13A-TP offers extended operating temperature range (-55°C ~ 175°C) with identical electrical specifications. This part is suitable for applications requiring enhanced thermal performance. Active status and ROHS3 compliance ensure supply availability.

Alternative Consideration: TV06B130J-G and TV06B130J-HF (Comchip Technology)

Both Comchip variants (TV06B130J-G and TV06B130J-HF) provide electrical equivalence with peak pulse current of 27.91A, matching the original specification within measurement tolerance. Active production status and ROHS3 compliance support design transitions. These parts are suitable where Comchip device qualification is already established in the supply chain.

Frequently Asked Questions (FAQ)

Q: Can I use SMBJ13A-TR with 29A peak pulse current instead of the original 27.9A specification?

A: Yes. The 29A rating provides additional transient energy absorption capability within the same 600W power dissipation envelope and identical voltage parameters. This represents a performance improvement suitable for the same application circuit.

Q: What is the difference between SMBJ13A-TP and SMBJ13A-TR packaging?

A: SMBJ13A-TP is supplied in Tape & Reel (TR) format by Micro Commercial Co. SMBJ13A-TR is supplied in Cut Tape (CT) & Digi-Reel® format by STMicroelectronics. Both use the same DO-214AA (SMB) component package. Selection depends on your assembly equipment and tape reel compatibility requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, maintaining environmental regulatory alignment with the original CD214B-T13ALF specification.

Q: Can I substitute the CD214B-T13ALF with SZ1SMB12AT3G or TPSMB15A?

A: No. SZ1SMB12AT3G has a 12V reverse standoff voltage (not 13V) and 19.9V clamping voltage (not 21.5V). TPSMB15A has a 12.8V reverse standoff voltage and 21.2V clamping voltage. These parts do not meet the mandatory voltage parameters for direct substitution.

Q: What is the MSL rating and why does it matter?

A: All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Components can be stored indefinitely without desiccant packaging or baking requirements prior to assembly, matching the original part's handling characteristics.

Q: Is operating temperature range a critical substitution parameter?

A: Operating temperature range is not a mandatory matching parameter if your application operates within the overlapping temperature window. The original CD214B-T13ALF operates -55°C ~ 150°C. All substitute parts support at least this range, with some offering extended capability to 175°C.
