ER3D Equivalent & Substitute Parts Reference

Part Overview

The ER3D is a superfast recovery rectifier diode manufactured by SMC Diode Solutions, rated for 200 V DC reverse voltage with 3 A average rectified current. This surface mount component in DO-214AB (SMC) package is designed for applications requiring fast switching characteristics with a reverse recovery time of 35 nanoseconds. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ER3D are identified based on strict electrical and mechanical parameter matching within the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) Maximum: 200 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) Maximum @ If: 950 mV @ 3 A
• Reverse Recovery Time (trr): 35 ns
• Operating Temperature Range: -65°C to 150°C

Mechanical Parameters (Must Match):

• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SS3D/B from EIC SEMICONDUCTOR INC. meets all mandatory electrical and mechanical substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

ER3D (SMC Diode Solutions):

• Primary selection for applications requiring SMC manufacturer qualification
• Active production status with 7,105 pieces in stock
• ROHS3 compliant with REACH affected status
• Reverse leakage current: 5 µA @ 200 V

SS3D/B (EIC SEMICONDUCTOR INC.):

• Parametric equivalent with identical electrical ratings and package
• Active production status with 11,082 pieces in stock
• ROHS3 compliant with REACH information available upon request
• Reverse leakage current: 10 µA @ 200 V (higher than ER3D but within acceptable tolerance for general-purpose applications)
• Higher inventory availability

Both parts are suitable for direct substitution in surface mount rectifier applications requiring 200 V, 3 A fast recovery diodes. Selection between ER3D and SS3D/B depends on manufacturer preference, inventory availability, and specific application leakage current requirements.

Frequently Asked Questions (FAQ)

Q: Can SS3D/B be used as a direct replacement for ER3D in existing designs?

A: Yes. The SS3D/B meets all critical electrical parameters (voltage, current, recovery time) and shares identical package and mounting specifications (DO-214AB, SMC, surface mount). Both components operate across the same temperature range (-65°C to 150°C) and comply with RoHS3 and MSL 1 requirements.

Q: What is the difference in reverse leakage current between ER3D and SS3D/B?

A: The ER3D specifies 5 µA @ 200 V reverse leakage, while the SS3D/B specifies 10 µA @ 200 V. This difference is within acceptable tolerance for general-purpose rectifier applications. Applications with strict leakage current specifications should verify compatibility with the higher leakage value of the SS3D/B.

Q: Are the packages physically identical?

A: Yes. Both ER3D and SS3D/B use the DO-214AB (SMC) surface mount package. PCB footprints and reflow soldering profiles are compatible between the two parts.

Q: What is the significance of the reverse recovery time specification?

A: The 35 nanosecond reverse recovery time (trr) classifies both parts as fast recovery diodes, suitable for high-frequency switching applications. This parameter is identical between ER3D and SS3D/B.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating. The ER3D lists REACH affected status, while SS3D/B indicates REACH information is available upon request. Consult supplier documentation for specific REACH compliance details when required.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturer qualification requirements and inventory considerations. Both parts are active production components with equivalent electrical performance. The SS3D/B offers higher inventory availability (11,082 pieces versus 7,105 pieces for ER3D).
