US2DA-TP Equivalent & Substitute Parts

Part Overview

The US2DA-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the US2DA-TP are identified based on the following substitution criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 2 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 1 V @ 2 A
• Reverse Recovery Time (trr): Equal to or less than 50 ns
• Current - Reverse Leakage @ Vr: Equal to or less than 5 µA @ 200 V
• Operating Temperature - Junction: Range must encompass or exceed -50°C ~ 150°C

The ESH1D-E3/61T from Vishay General Semiconductor - Diodes Division meets the mandatory matching parameters. However, the Current - Average Rectified (Io) rating of 1 A is below the 2 A requirement of the main part, which restricts its use to applications requiring 1 A or less.

Parameter Comparison

Engineering Selection Recommendations

US2DA-TP Selection Criteria: The US2DA-TP is the primary component choice for applications requiring 2 A average rectified current at 200 V DC reverse voltage in a surface mount DO-214AC package. This part is Active product status with ROHS3 compliance and MSL 1 rating, suitable for standard manufacturing environments without moisture sensitivity constraints.

ESH1D-E3/61T Selection Criteria: The ESH1D-E3/61T is suitable for applications requiring 1 A or less average rectified current at 200 V DC reverse voltage. This substitute part is Active product status with ROHS3 compliance and MSL 1 rating. The ESH1D-E3/61T exhibits superior performance characteristics including lower reverse recovery time (25 ns versus 50 ns) and lower reverse leakage current (1 µA versus 5 µA). The operating temperature range extends to -55°C and 175°C, providing broader thermal operating margins compared to the US2DA-TP.

Substitution Limitation: The ESH1D-E3/61T cannot serve as a direct substitute for the US2DA-TP in applications requiring the full 2 A current rating. Current derating to 1 A maximum is mandatory when using the ESH1D-E3/61T.

Frequently Asked Questions (FAQ)

Q: Can the ESH1D-E3/61T replace the US2DA-TP in all applications?

A: No. The ESH1D-E3/61T has a maximum average rectified current rating of 1 A, while the US2DA-TP is rated for 2 A. The ESH1D-E3/61T is suitable only for applications requiring 1 A or less. Applications requiring 2 A operation must use the US2DA-TP or an equivalent 2 A rated component.

Q: Are the packages mechanically identical?

A: Yes. Both the US2DA-TP and ESH1D-E3/61T use the DO-214AC (SMA) surface mount package. Mechanical compatibility and PCB footprint are identical.

Q: What are the compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Compliance profiles are equivalent.

Q: Does the ESH1D-E3/61T have better performance characteristics?

A: The ESH1D-E3/61T exhibits lower reverse recovery time (25 ns versus 50 ns) and lower reverse leakage current (1 µA versus 5 µA). The operating temperature range is also extended (-55°C to 175°C versus -50°C to 150°C). These characteristics represent performance improvements within the constraints of the 1 A current rating.

Q: What is the forward voltage difference at rated current?

A: The US2DA-TP has a maximum forward voltage of 1 V at 2 A. The ESH1D-E3/61T has a maximum forward voltage of 0.9 V at 1 A. Direct comparison at identical current levels is not applicable due to different current ratings.

Q: Are both parts suitable for fast recovery applications?

A: Yes. Both parts are classified as Fast Recovery with recovery time ≤ 500 ns for currents > 200 mA. The ESH1D-E3/61T has a faster recovery time specification (25 ns versus 50 ns).
