SD05C-TP Equivalent & Substitute Parts

Part Overview

The SD05C-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage with a 14.6V maximum clamping voltage and 24A peak pulse current capability in the SOD-323 package. The SD05C-TP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD05C-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff: 5V (Max)
• Voltage - Breakdown (Min): 6V
• Package / Case: SOD-323
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Performance Parameters (Allowable Variation):

• Voltage - Clamping (Max) @ Ipp: Must not exceed application requirements
• Current - Peak Pulse: Must meet or exceed circuit protection demands
• Power - Peak Pulse: Must support transient energy dissipation

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: Must cover application environment

The SD05CH-TP qualifies as a direct substitute based on matching voltage standoff, breakdown voltage, package type, and mounting configuration. Enhanced performance parameters (15V clamping, 34A peak pulse, 500W peak power) provide superior protection margins while maintaining electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SD05CH-TP is the qualified substitute for the obsolete SD05C-TP. Both components share identical voltage standoff and breakdown specifications, ensuring direct electrical compatibility in existing circuit designs. The SD05CH-TP maintains active product status with full ROHS3 compliance, providing long-term supply chain stability.

The SD05CH-TP exhibits enhanced performance characteristics: clamping voltage increases from 14.6V to 15V, peak pulse current increases from 24A to 34A, and peak pulse power increases from 350W to 500W. These improvements provide additional protection margin without introducing incompatibility. The operating temperature range of the SD05CH-TP (-55°C to 125°C) covers standard industrial applications; designs requiring the extended upper temperature range of the SD05C-TP (-55°C to 150°C) require thermal analysis validation.

Both components utilize SOD-323 packaging in surface-mount configuration, ensuring PCB layout and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SD05CH-TP directly replace the SD05C-TP in existing designs?

A: Yes. Both components share identical voltage standoff (5V Max), breakdown voltage (6V Min), and SOD-323 package specifications. The SD05CH-TP provides enhanced performance with higher clamping voltage, peak pulse current, and power dissipation capability.

Q: What is the primary difference between these two parts?

A: The SD05C-TP is obsolete; the SD05CH-TP is active. The SD05CH-TP provides superior transient protection with 15V clamping versus 14.6V, 34A peak pulse versus 24A, and 500W peak power versus 350W. Operating temperature ranges differ: SD05C-TP supports -55°C to 150°C; SD05CH-TP supports -55°C to 125°C.

Q: Are there packaging differences between these parts?

A: No. Both components use SOD-323 (SC-76) surface-mount packaging. Tape & Reel (TR) packaging is available for the SD05CH-TP, supporting automated assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the SD05C-TP and SD05CH-TP are ROHS3 compliant.

Q: Which part should be selected for new designs?

A: The SD05CH-TP should be selected for new designs due to active product status and superior performance characteristics. The SD05C-TP is suitable only for legacy design maintenance where supply exists.
