HS3M V7G Equivalent & Substitute Parts

Part Overview

The HS3M V7G is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. Manufactured by Taiwan Semiconductor Corporation, this component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing design requirements and procurement needs. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while supporting surface mount assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS3M V7G are identified based on strict electrical and mechanical parameter matching within the rectifier diode category. The substitution criteria are:

Primary Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 3 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Standard

Parts meeting all primary parameters and maintaining compatibility within secondary parameter tolerances are classified as direct substitutes or parametric equivalents. Variations in reverse recovery time, reverse leakage current, and capacitance within the fast recovery classification do not preclude substitution when primary electrical ratings and package specifications are identical.

Engineering Selection Recommendations

HS3M (SURGE Manufacturer)

The HS3M from SURGE is a direct manufacturer equivalent with identical electrical specifications to the original HS3M V7G. This part maintains all primary and secondary parameters without deviation. Product status is active with 30,100 units in stock, ensuring supply continuity. RoHS3 compliance and MSL 1 rating confirm environmental and handling compatibility. This substitute is the primary selection for direct replacement applications.

UF3M_R1_00001 (Panjit International Inc.)

The UF3M_R1_00001 is a parametric equivalent meeting all primary electrical and mechanical requirements. Reverse recovery time is 100 ns compared to 75 ns in the original part, and reverse leakage current is 1 µA compared to 10 µA. Capacitance is 63 pF versus 50 pF. These variations remain within the fast recovery diode classification and do not compromise functional compatibility in standard rectification applications. Product status is active with 1,850 units available. RoHS3 compliance and MSL 1 rating are confirmed. This substitute is suitable for applications where the improved reverse leakage characteristic is beneficial.

Both substitutes are packaged in DO-214AB (SMC) surface mount format and operate across the identical temperature range, supporting direct PCB assembly without design modification.

Frequently Asked Questions (FAQ)

Q: Can the HS3M from SURGE directly replace the HS3M V7G?

A: Yes. The HS3M from SURGE is a direct equivalent with identical voltage rating (1000 V), current rating (3 A), forward voltage (1.7 V @ 3 A), reverse recovery time (75 ns), reverse leakage current (10 µA @ 1000 V), and package specification (DO-214AB, SMC). No circuit modifications are required.

Q: What are the differences between the UF3M_R1_00001 and the original HS3M V7G?

A: The UF3M_R1_00001 maintains identical voltage, current, and forward voltage specifications. Reverse recovery time is 100 ns versus 75 ns, reverse leakage current is 1 µA versus 10 µA, and capacitance is 63 pF versus 50 pF. All parameters remain within fast recovery diode specifications and do not affect standard rectification performance.

Q: Are all three parts in the same package?

A: Yes. The HS3M V7G, HS3M (SURGE), and UF3M_R1_00001 are all packaged in DO-214AB (SMC) surface mount format with identical footprints and mounting requirements.

Q: What is the difference between the HS3M V7G and HS3M in terms of product status?

A: The HS3M V7G is discontinued at DiGi Electronics. The HS3M from SURGE is active with 30,100 units in stock, providing ongoing availability for procurement.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All three parts are ROHS3 compliant and rated MSL 1 (Unlimited), confirming environmental and moisture sensitivity compatibility for surface mount assembly processes.

Q: Which substitute should be selected for new designs?

A: The HS3M from SURGE is the primary selection due to identical electrical specifications and active product status. The UF3M_R1_00001 is suitable as an alternative when improved reverse leakage characteristics are advantageous.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts share the DO-214AB (SMC) package footprint and identical electrical ratings for voltage, current, and temperature range, enabling direct substitution without PCB redesign.
