RS3D Equivalent & Substitute Parts

Part Overview

The RS3D is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 200 V DC reverse voltage and 3 A average rectified current in a Surface Mount SMC (DO-214AB) package. This diode is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when applications require alternative sourcing, inventory availability, or specific performance characteristics within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS3D are identified based on strict equivalence of the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 200 V
• Current Rating: Average rectified current must equal 3 A
• Package Type: Surface Mount SMC (DO-214AB) package required
• Technology Classification: Standard rectifier diode technology
• Compliance: ROHS3 compliance required

The ES3D from Diotec Semiconductor meets all substitution criteria. Both diodes share identical voltage and current ratings, package configuration, and regulatory compliance status. Differences in reverse recovery time (trr) and forward voltage characteristics are secondary performance variations that do not disqualify substitution within the same electrical class.

Parameter Comparison

Engineering Selection Recommendations

Both the RS3D and ES3D are Active product status diodes with ROHS3 compliance, qualifying them for equivalent substitution in 200 V, 3 A rectifier applications using DO-214AB Surface Mount packages.

The ES3D exhibits superior performance characteristics in reverse recovery time (20 ns versus 150 ns) and forward voltage drop (0.9 V versus 1.3 V at 3 A), resulting in lower switching losses and reduced heat dissipation. The ES3D also demonstrates lower reverse leakage current (5 µA versus 10 µA at 200 V).

The RS3D operates across a wider junction temperature range (-55°C to 150°C) compared to the ES3D (-50°C to 150°C), providing extended low-temperature performance capability.

Selection between these parts depends on application requirements: choose RS3D for extended low-temperature operation; choose ES3D for applications prioritizing reduced power dissipation and faster switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can the ES3D replace the RS3D in existing designs?

A: Yes. Both diodes are rated for 200 V reverse voltage and 3 A average rectified current in identical DO-214AB Surface Mount packages. Electrical and mechanical compatibility is established.

Q: What are the key differences between RS3D and ES3D?

A: The ES3D has faster reverse recovery time (20 ns versus 150 ns), lower forward voltage drop (0.9 V versus 1.3 V at 3 A), and lower reverse leakage current (5 µA versus 10 µA). The RS3D supports a lower minimum junction temperature (-55°C versus -50°C).

Q: Are both diodes RoHS compliant?

A: Yes. Both RS3D and ES3D are ROHS3 compliant.

Q: Do these diodes use the same package?

A: Yes. Both use the DO-214AB Surface Mount SMC package, ensuring identical PCB footprint and mounting compatibility.

Q: Which diode should be selected for high-frequency switching applications?

A: The ES3D is suitable for high-frequency applications due to its 20 ns reverse recovery time, compared to the RS3D's 150 ns recovery time.

Q: Which diode should be selected for low-temperature environments?

A: The RS3D supports operation down to -55°C junction temperature, while the ES3D is rated to -50°C. Select RS3D for applications requiring extended low-temperature performance.

Q: Are there inventory considerations between these parts?

A: The RS3D has 3,192 pieces in stock. The ES3D has 131,200 pieces in stock, providing significantly higher availability.
