CD214A-T130CALF Equivalent & Substitute Parts

Part Overview

The CD214A-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 1.9A peak pulse current capability in a DO-214AC (SMA) package. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CD214A-T130CALF is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 130V
Voltage - Clamping (Max) @ Ipp: 209V (±tolerance acceptable)
Current - Peak Pulse (10/1000µs): 1.9A (±tolerance acceptable)
Package / Case: DO-214AC (SMA)
Type: Zener, Bidirectional, single channel
Operating Temperature Range: minimum -55°C to 150°C

Substitute parts are grouped into two categories:

Direct Equivalents: Parts meeting all critical parameters within acceptable tolerances, maintaining identical electrical performance and package specifications.

Similar Alternatives: Parts with comparable voltage and current ratings but with variations in clamping voltage, peak pulse current specifications, or operating temperature ranges that may require application-level verification.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

SMAJ130CA (Meritek) and SMAJ130CA-TP (Micro Commercial Co) are direct functional equivalents to the CD214A-T130CALF. Both maintain 130V reverse standoff voltage, 209V clamping voltage, and 1.9A peak pulse current specifications. Both manufacturers provide active product status with ROHS3 compliance. SMAJ130CA-TP offers extended operating temperature range to 175°C, providing additional thermal margin for demanding applications.

Alternative Substitute (Voltage/Current Variation):

SMAJ130CA-TR (STMicroelectronics) maintains the 130V reverse standoff voltage but specifies 265V maximum clamping voltage and 9A peak pulse current (8/20µs pulse definition). This part provides higher transient energy absorption capability and is suitable for applications requiring enhanced overvoltage protection margin.

Limited Compatibility Substitute:

SMAJP4KE160CA-TP (Micro Commercial Co) operates at 136V reverse standoff voltage with 219V clamping voltage, representing a voltage shift from the original specification. This part is suitable only for applications where the higher standoff voltage and clamping voltage are acceptable within system design tolerances.

Frequently Asked Questions (FAQ)

Q: Can SMAJ130CA-TR be used as a direct replacement for CD214A-T130CALF?

A: SMAJ130CA-TR maintains identical reverse standoff voltage (130V) and package (DO-214AC/SMA) but specifies higher clamping voltage (265V) and peak pulse current (9A at 8/20µs pulse definition versus 1.9A at 10/1000µs). Application-level verification is required to confirm compatibility with circuit protection requirements.

Q: What is the difference between SMAJ130CA and SMAJ130CA-TP?

A: Both parts are functionally equivalent with 130V standoff voltage and 209V clamping voltage. SMAJ130CA-TP is manufactured by Micro Commercial Co with extended operating temperature range (-55°C to 175°C) compared to SMAJ130CA (Meritek, -55°C to 150°C). SMAJ130CA-TP is supplied in Tape & Reel packaging.

Q: Is SMAJP4KE160CA-TP compatible with the original CD214A-T130CALF specification?

A: SMAJP4KE160CA-TP operates at 136V reverse standoff voltage and 219V clamping voltage, representing deviations from the original 130V/209V specification. Compatibility depends on circuit design tolerance for higher voltage thresholds. This part is classified as a similar alternative rather than a direct equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: SMAJ130CA, SMAJ130CA-TP, and SMAJ130CA-TR are confirmed ROHS3 compliant. SMAJP4KE160CA-TP RoHS status is not specified in available documentation.

Q: What packaging options are available for substitute parts?

A: SMAJ130CA is supplied in Tape & Reel (TR) packaging. SMAJ130CA-TP is available in Tape & Reel (TR). SMAJ130CA-TR is supplied in Cut Tape (CT) & Digi-Reel® packaging. SMAJP4KE160CA-TP is supplied in Bulk packaging. All parts use DO-214AC (SMA) surface mount package.
