HS3G Equivalent & Substitute Parts

Part Overview

The HS3G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 3 A average rectified current. The device is packaged in DO-214AB (SMC) surface mount configuration and classified as a fast recovery diode with a reverse recovery time of 50 ns. This component is suitable for power supply circuits, switching applications, and general rectification tasks requiring fast switching characteristics.

The HS3G maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the surface mount DO-214AB package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS3G rectifier diode is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns
• Operating Temperature Range: -55°C to 150°C
• RoHS Compliance: ROHS3 Compliant

The substitute part UF3G_R1_00001 (Panjit International Inc.) meets all mandatory electrical and mechanical parameters. Both devices operate within identical voltage and current ratings, share the same surface mount package configuration, and maintain equivalent fast recovery switching characteristics. Both components are Active status products with full RoHS3 compliance and unlimited moisture sensitivity level.

Parameter Comparison

Engineering Selection Recommendations

The UF3G_R1_00001 (Panjit International Inc.) is a direct electrical and mechanical equivalent to the HS3G. Both components satisfy identical application requirements for 400 V, 3 A fast recovery rectification in surface mount DO-214AB packaging.

Selection Basis:

Both parts maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance across industrial and commercial applications. The reverse recovery time of 50 ns in both devices supports high-frequency switching applications without performance degradation.

The UF3G_R1_00001 exhibits lower reverse leakage current (1 µA versus 10 µA at 400 V) and marginally lower junction capacitance (75 pF versus 80 pF at 4 V, 1 MHz), representing minor performance enhancements within acceptable tolerance ranges for general-purpose rectification circuits.

Component selection between HS3G and UF3G_R1_00001 may be determined by availability, lead time, supplier preference, or cost considerations, as both devices deliver equivalent functional performance within specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the UF3G_R1_00001 be used as a direct replacement for the HS3G in existing designs?

A: Yes. Both devices are rated for 400 V DC reverse voltage and 3 A average rectified current with identical fast recovery characteristics (50 ns reverse recovery time). The DO-214AB surface mount package is mechanically and electrically compatible. No circuit modifications are required.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Voltage - DC Reverse (Vr) rating of 400 V, (2) Current - Average Rectified (Io) rating of 3 A, (3) Fast Recovery speed classification with 50 ns reverse recovery time, (4) DO-214AB surface mount package configuration, and (5) Operating temperature range of -55°C to 150°C.

Q: Are there differences in reverse leakage current between the HS3G and UF3G_R1_00001?

A: Yes. The HS3G specifies 10 µA reverse leakage at 400 V, while the UF3G_R1_00001 specifies 1 µA at 400 V. The lower leakage in the UF3G_R1_00001 represents improved performance and does not affect substitution compatibility. Both values are within acceptable ranges for general-purpose rectification applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the HS3G and UF3G_R1_00001 are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain Moisture Sensitivity Level 1 (unlimited). Regulatory compliance is equivalent across both components.

Q: What is the significance of the DO-214AB package designation?

A: DO-214AB is the industry-standard surface mount package for general-purpose rectifier diodes in this voltage and current class. Both the HS3G and UF3G_R1_00001 use this package, ensuring mechanical compatibility with existing PCB layouts, solder reflow processes, and automated assembly equipment without modification.

Q: Can the HS3G and UF3G_R1_00001 be mixed within the same production batch?

A: Yes. Both components meet identical electrical specifications, package requirements, and regulatory standards. Mixed sourcing is permissible from a functional and compliance perspective. However, design documentation and bill of materials should clearly identify the specific part number used in each production lot for traceability purposes.
