CTAN1424V-G Equivalent & Substitute Parts

Part Overview

The CTAN1424V-G is a bidirectional transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This component features a 24V reverse standoff voltage with a 43V maximum clamping voltage and 5A peak pulse current rating in a 14-SOIC surface mount package.

The CTAN1424V-G is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTAN1424V-G is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 24V nominal
• Voltage - Clamping (Max) @ Ipp: 43V maximum
• Current - Peak Pulse: 5A (8/20µs)
• Power - Peak Pulse: 300W
• Package / Case: 14-SOIC surface mount
• Operating Temperature Range: -55°C ~ 125°C (TJ)

The SMDA24C-8.TBT from Semtech Corporation meets all critical electrical parameters and physical package requirements. While the SMDA24C-8.TBT features 8 bidirectional channels compared to the CTAN1424V-G's 5 channels, this represents an enhancement in protection capability within the same package footprint and does not compromise compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The SMDA24C-8.TBT is the qualified substitute for the CTAN1424V-G based on the following factors:

Electrical Equivalence: All critical voltage and current parameters are identical. The clamping voltage, reverse standoff voltage, and peak pulse current specifications match exactly, ensuring functional compatibility in the original application circuit.

Package Compatibility: Both components use the 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width), allowing direct PCB footprint compatibility without layout modifications.

Compliance Status: The SMDA24C-8.TBT maintains RoHS compliance and carries an active product status, ensuring long-term availability and supply chain stability compared to the obsolete CTAN1424V-G.

Enhanced Protection: The SMDA24C-8.TBT provides 8 bidirectional channels versus 5 in the original part, offering increased protection capability within the same package envelope.

Frequently Asked Questions (FAQ)

Q: Can the SMDA24C-8.TBT be used as a direct replacement for the CTAN1424V-G?

A: Yes. The SMDA24C-8.TBT meets all critical electrical specifications (24V standoff, 43V clamping, 5A peak pulse current, 300W power rating) and uses the identical 14-SOIC package. The increased channel count (8 vs. 5) does not affect compatibility.

Q: What is the significance of the different channel counts?

A: The CTAN1424V-G provides 5 bidirectional protection channels, while the SMDA24C-8.TBT provides 8 channels. This means the substitute part offers additional protection paths within the same physical package, which is beneficial for multi-line protection applications.

Q: Are there any PCB layout considerations when switching to the SMDA24C-8.TBT?

A: No. Both parts use the 14-SOIC package with identical dimensions and pin spacing. Existing PCB layouts require no modification for this substitution.

Q: Why is the CTAN1424V-G listed as obsolete?

A: The CTAN1424V-G has been discontinued by Comchip Technology. The SMDA24C-8.TBT from Semtech Corporation is an active product that provides equivalent electrical performance and serves as the recommended alternative for new designs and ongoing production support.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The CTAN1424V-G carries ROHS3 certification, while the SMDA24C-8.TBT carries standard RoHS certification. Both meet environmental and regulatory requirements for industrial and commercial applications.
