SD36C-TP Equivalent & Substitute Parts

Part Overview

The SD36C-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 36V reverse standoff voltage with 80V maximum clamping voltage and 3A peak pulse current capability in an SOD-323 package.

The SD36C-TP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD36C-TP is determined by the following critical parameters:

• Package Compatibility: Both parts must use SOD-323 surface-mount packaging to ensure PCB footprint compatibility
• Voltage Rating: Reverse standoff voltage and clamping voltage must meet or exceed the original specification to maintain protection thresholds
• Current Handling: Peak pulse current capability must support the application's transient energy requirements
• Thermal Performance: Operating temperature range must accommodate the application environment
• Compliance: RoHS3 compliance ensures regulatory alignment

The SD36CH-TP qualifies as a substitute based on matching package type (SOD-323), identical reverse standoff voltage (36V Max), and active product status, despite differences in clamping voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

The SD36CH-TP is the designated substitute for the obsolete SD36C-TP. Both components share identical reverse standoff voltage specifications and package geometry, ensuring direct PCB compatibility.

The SD36CH-TP offers enhanced performance characteristics: higher peak pulse current (6A versus 3A) and greater peak pulse power (500W versus 240W), providing superior transient suppression capability. The lower clamping voltage (50V versus 80V) delivers tighter voltage regulation during transient events.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The SD36CH-TP is actively manufactured, eliminating supply chain risk associated with the obsolete SD36C-TP.

The SD36CH-TP's maximum operating temperature of 125°C is 25°C lower than the SD36C-TP. Applications requiring operation above 125°C junction temperature require thermal analysis to confirm suitability.

Frequently Asked Questions (FAQ)

Q: Can the SD36CH-TP directly replace the SD36C-TP on existing PCBs?

A: Yes. Both components use identical SOD-323 surface-mount packaging and share the same reverse standoff voltage rating (36V Max), ensuring direct footprint compatibility without PCB modification.

Q: What are the key differences between these parts?

A: The SD36CH-TP provides higher current handling (6A versus 3A) and greater power dissipation (500W versus 240W). The clamping voltage is lower (50V versus 80V), resulting in tighter voltage suppression. The SD36CH-TP has a maximum operating temperature of 125°C compared to 150°C for the SD36C-TP.

Q: Is the SD36CH-TP suitable for all applications using the SD36C-TP?

A: The SD36CH-TP is suitable for applications where the maximum junction temperature does not exceed 125°C and where the lower clamping voltage (50V) meets protection requirements. Applications requiring operation above 125°C or higher clamping voltage thresholds require alternative evaluation.

Q: Are both parts RoHS compliant?

A: Yes. Both the SD36C-TP and SD36CH-TP are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the packaging format for the SD36CH-TP?

A: The SD36CH-TP is supplied in Tape & Reel (TR) format in SOD-323 packaging, identical to the SD36C-TP package type.
