CD214A-T11CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T11CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features an 11V reverse standoff voltage with an 18.2V maximum clamping voltage and 22A peak pulse current capability in a DO-214AC (SMA) package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD214A-T11CALF is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage: 11V (typical)
• Breakdown voltage minimum: 12.2V
• Maximum clamping voltage at peak pulse current: 18.2V
• Peak pulse current rating: 22A (10/1000µs waveform)
• Peak pulse power dissipation: 400W
• Package type: DO-214AC (SMA)
• Mounting configuration: Surface mount
• Diode type: Zener
• Channel configuration: Single bidirectional channel
• Application category: General purpose

All identified substitute parts maintain these electrical specifications and physical package requirements. Variations in operating temperature range, product status, and manufacturer do not affect functional substitutability within the defined electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

SMAJ11CA (MDD) is the primary direct substitute for the CD214A-T11CALF. This part maintains identical electrical specifications and package configuration while offering active product status and higher inventory availability (50,300 units). Both parts are ROHS3 compliant with matching regulatory classifications.

SMAJ11CA-TP (Micro Commercial Co) serves as an alternative substitute with equivalent electrical performance. This variant offers an extended operating temperature range (-55°C ~ 175°C TA) compared to the original part, providing additional thermal margin in applications subject to elevated ambient conditions. Product status is active with adequate inventory (5,083 units).

Selection between SMAJ11CA and SMAJ11CA-TP should be based on procurement availability, lead time requirements, and thermal operating environment specifications. Both parts satisfy the electrical and mechanical requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SMAJ11CA replace CD214A-T11CALF in existing designs?

A: Yes. SMAJ11CA maintains identical electrical parameters (11V standoff, 18.2V clamping, 22A peak current) and package configuration (DO-214AC SMA). No circuit modifications are required.

Q: What is the difference between SMAJ11CA and SMAJ11CA-TP?

A: Both parts are electrically equivalent with identical voltage and current ratings. SMAJ11CA-TP offers an extended operating temperature range (-55°C ~ 175°C TA) versus standard specifications. Selection depends on thermal environment requirements and supplier availability.

Q: Are all substitute parts RoHS compliant?

A: Yes. CD214A-T11CALF, SMAJ11CA, and SMAJ11CA-TP are all ROHS3 compliant with matching regulatory status.

Q: Does packaging format affect substitutability?

A: All identified substitutes use DO-214AC (SMA) surface-mount packaging. Tape & Reel (TR) packaging format is a handling and delivery specification that does not affect electrical performance or PCB assembly compatibility.

Q: Why is the original CD214A-T11CALF listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. Functionally equivalent alternatives from active manufacturers (MDD, Micro Commercial Co) provide continuity for designs requiring 11V/18.2V TVS diode protection.
