HS3J V7G Equivalent & Substitute Parts

Part Overview

The HS3J V7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter tolerances for the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectifier diodes HS3J V7G is determined by matching the following critical parameters:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (minimum)

Compliance Requirements:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1 or better
• REACH Unaffected status

Parts meeting these criteria are classified as direct equivalents or functional substitutes. Secondary parameters including reverse recovery time, forward voltage, and capacitance may vary within acceptable ranges for general-purpose rectification applications without affecting primary circuit function.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - HS3J:

The HS3J from Taiwan Semiconductor Corporation is the direct equivalent to HS3J V7G, differing only in packaging format (Tape & Reel versus unspecified). This part maintains identical electrical specifications and is currently in active product status with 6600 pieces in stock. Selection of HS3J is appropriate for applications requiring the exact electrical and thermal characteristics of the original part specification.

Functional Substitute - S3J-E3/57T:

The S3J-E3/57T from Vishay General Semiconductor - Diodes Division is a functional substitute meeting all primary matching criteria: 600 V reverse voltage rating, 3 A average rectified current, DO-214AB surface mount package, and identical operating temperature range. This part is in active product status with 15200 pieces in stock. The S3J-E3/57T exhibits different secondary characteristics (standard recovery speed versus fast recovery, 2.5 µs reverse recovery time versus 75 ns, and 1.15 V forward voltage at 2.5 A) and is suitable for general-purpose rectification applications where these parameter variations do not impact circuit performance. Compliance certifications (ROHS3, MSL 1, REACH Unaffected) are equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can HS3J be used as a direct replacement for HS3J V7G?

A: Yes. The HS3J is the direct equivalent, maintaining identical voltage rating (600 V), current rating (3 A), package type (DO-214AB, SMC), and operating temperature range (-55°C to 150°C). The only difference is packaging format (Tape & Reel versus unspecified). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What are the key differences between HS3J and S3J-E3/57T?

A: Both parts share identical voltage, current, package, and temperature specifications. The S3J-E3/57T differs in recovery speed classification (standard recovery >500 ns versus fast recovery ≤500 ns), reverse recovery time (2.5 µs versus 75 ns), and capacitance (60 pF versus 50 pF at 4 V, 1 MHz). These differences do not affect compatibility in general-purpose rectification circuits.

Q: Are packaging format differences between Tape & Reel and Cut Tape significant for substitution?

A: Packaging format differences (Tape & Reel, Cut Tape, or unspecified) do not affect electrical or mechanical compatibility. Format selection depends on assembly process requirements and handling procedures. All three parts are surface mount components in identical DO-214AB packages suitable for automated placement equipment.

Q: Can S3J-E3/57T be used in applications requiring fast recovery characteristics?

A: No. The S3J-E3/57T is classified as standard recovery (>500 ns) with 2.5 µs reverse recovery time, whereas the original HS3J V7G specifies fast recovery (≤500 ns) with 75 ns reverse recovery time. Applications requiring fast recovery performance must use HS3J or equivalent fast recovery variants.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. Both HS3J and S3J-E3/57T are ROHS3 compliant and REACH unaffected, matching the compliance status of HS3J V7G. All parts are suitable for applications with environmental and regulatory compliance requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All three parts (HS3J V7G, HS3J, and S3J-E3/57T) carry this rating, eliminating moisture sensitivity as a selection factor.
