UPT5/TR7 Equivalent & Substitute Parts

Part Overview

The UPT5/TR7 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage with a 9.5V maximum clamping voltage and 15.7A peak pulse current capability in a surface-mount DO-216AA (Powermite 1) package.

The UPT5/TR7 is classified as an obsolete product. 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

Substitute parts for the UPT5/TR7 are identified based on strict electrical and mechanical parameter compatibility within the Transient Voltage Suppressor category. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Clamping (Max) @ Ipp: 9.5V maximum
• Current - Peak Pulse (10/1000µs): minimum 15.7A
• Package / Case: DO-216AA
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Substitution Categories:

Direct Equivalent: UPT5E3/TR13 matches all electrical parameters and packaging specifications identically to the main part, with the distinction of active product status and tape & reel packaging format.

Similar Substitute: SM2T6V8A from STMicroelectronics operates within the same voltage and package envelope with comparable electrical performance, though with variations in peak pulse current (19.6A vs. 15.7A) and peak pulse power (200W vs. 1000W).

Parameter Comparison

Engineering Selection Recommendations

UPT5E3/TR13 (Direct Equivalent): This part is the primary recommended substitute for the obsolete UPT5/TR7. It is manufactured by the same supplier (Microchip Technology) and maintains identical electrical specifications and package configuration. The UPT5E3/TR13 holds active product status, ensuring long-term availability and supply chain stability. This part is ROHS3 compliant and carries the same moisture sensitivity rating. The only operational difference is packaging format (tape & reel vs. bulk), which does not affect electrical performance or board-level compatibility.

SM2T6V8A (Similar Substitute): The SM2T6V8A from STMicroelectronics is a compatible alternative when UPT5E3/TR13 availability is constrained. This part operates within the same voltage protection envelope (5V standoff, 9.2V clamping) and uses the identical DO-216AA package. The SM2T6V8A provides higher peak pulse current capability (19.6A vs. 15.7A), making it suitable for applications requiring enhanced transient protection. However, the peak pulse power rating is lower (200W vs. 1000W). This part is ROHS3 compliant and carries unlimited moisture sensitivity rating. The operating temperature range is not specified in available documentation.

Selection between these substitutes should be based on supply availability, cost considerations, and specific application requirements regarding peak pulse power dissipation.

Frequently Asked Questions (FAQ)

Q: Can UPT5E3/TR13 be used as a direct replacement for UPT5/TR7?

A: Yes. The UPT5E3/TR13 is electrically and mechanically identical to the UPT5/TR7. Both parts feature 5V reverse standoff voltage, 9.5V clamping voltage, 15.7A peak pulse current, and DO-216AA surface-mount packaging. The primary difference is product status (active vs. obsolete) and packaging format (tape & reel vs. bulk). Board-level performance and compatibility are equivalent.

Q: What are the key differences between UPT5E3/TR13 and SM2T6V8A?

A: Both parts share the same 5V reverse standoff voltage, similar clamping voltages (9.5V vs. 9.2V), and identical DO-216AA packaging. The SM2T6V8A provides higher peak pulse current (19.6A vs. 15.7A) but lower peak pulse power (200W vs. 1000W). The UPT5E3/TR13 is from Microchip Technology, while SM2T6V8A is from STMicroelectronics. Both are ROHS3 compliant with unlimited moisture sensitivity.

Q: Is the DO-216AA package compatible across all three parts?

A: Yes. All three parts (UPT5/TR7, UPT5E3/TR13, and SM2T6V8A) use the DO-216AA surface-mount package, also known as Powermite 1 for Microchip parts. This ensures mechanical and board-level compatibility without requiring PCB redesign.

Q: What is the significance of the obsolete status of UPT5/TR7?

A: Obsolete status indicates that Microchip Technology has discontinued manufacturing and support for this part. Existing inventory may be limited, and long-term availability cannot be guaranteed. The UPT5E3/TR13 is the recommended migration path, as it maintains identical specifications while offering active product status and assured supply continuity.

Q: Are there compliance or regulatory differences between these parts?

A: Both UPT5E3/TR13 and SM2T6V8A are ROHS3 compliant and REACH unaffected. Both carry ECCN EAR99 classification and HTSUS code 8541.10.0080. Moisture sensitivity level is 1 (unlimited) for all parts. No regulatory barriers exist to substitution.

Q: Can SM2T6V8A be used in applications requiring 1000W peak pulse power?

A: No. The SM2T6V8A is rated for 200W peak pulse power, which is significantly lower than the 1000W rating of UPT5/TR7 and UPT5E3/TR13. Applications requiring 1000W peak pulse power dissipation must use UPT5E3/TR13 or equivalent parts with matching power ratings.

Q: What packaging formats are available for these substitutes?

A: UPT5/TR7 is supplied in bulk packaging. UPT5E3/TR13 is available in tape & reel (TR) format. SM2T6V8A is available in cut tape (CT) and Digi-Reel® formats. Packaging format selection depends on manufacturing process requirements and volume considerations but does not affect electrical performance.
