HS5D R7 Equivalent & Substitute Parts

Part Overview

The HS5D R7 is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. 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 and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the HS5D R7 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 200 V
• Current - Average Rectified (Io): Must equal or exceed 5 A
• Voltage - Forward (Vf) (Max) @ If: Must not exceed specified forward voltage at rated current
• Reverse Recovery Time (trr): Must comply with fast recovery classification (≤ 500ns, > 200mA)
• Current - Reverse Leakage @ Vr: Must not exceed specified leakage at rated reverse voltage

Mechanical Parameters:

• Package / Case: Must be DO-214AB (SMC) surface mount
• Operating Temperature - Junction: Must cover -55°C ~ 150°C range
• Mounting Type: Must be Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Technology: Standard

Two substitute parts meet these criteria with the following distinctions:

US5DC-HF (Parametric Equivalent): Matches all electrical specifications exactly, including 5 A current rating, 200 V reverse voltage, 1 V forward voltage at 5 A, and 50 ns reverse recovery time. Manufactured by Comchip Technology with active product status.

RS3D-M3/9AT (Similar Substitute): Maintains 200 V reverse voltage and fast recovery speed classification but operates at reduced current rating of 3 A. Forward voltage is 1.3 V @ 2.5 A with 150 ns reverse recovery time. Manufactured by Vishay General Semiconductor with active product status.

Engineering Selection Recommendations

US5DC-HF Selection Criteria:

The US5DC-HF manufactured by Comchip Technology is a parametric equivalent substitute for the HS5D R7. This part maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 5 A average rectified current, 1 V forward voltage at 5 A, and 50 ns reverse recovery time. The US5DC-HF holds active product status, ensuring ongoing availability and supply chain continuity. Both components comply with ROHS3 standards, carry MSL 1 (Unlimited) moisture sensitivity classification, and operate across the identical temperature range of -55°C to 150°C. The DO-214AB (SMC) surface mount package is identical, enabling direct mechanical and electrical substitution without circuit board redesign. The US5DC-HF exhibits lower reverse leakage current (5 µA @ 200 V versus 10 µA @ 200 V) and reduced junction capacitance (50 pF versus 80 pF), representing improved performance characteristics.

RS3D-M3/9AT Selection Criteria:

The RS3D-M3/9AT manufactured by Vishay General Semiconductor is a similar substitute applicable only to circuits where the 5 A current rating is not a limiting design constraint. This part maintains 200 V reverse voltage and fast recovery speed classification but operates at 3 A average rectified current. The forward voltage is 1.3 V @ 2.5 A with 150 ns reverse recovery time. The RS3D-M3/9AT holds active product status and complies with all regulatory requirements matching the main part. Selection of this substitute requires circuit analysis to confirm that the reduced current rating and increased forward voltage do not compromise system performance or thermal management.

Frequently Asked Questions (FAQ)

Q: Can the US5DC-HF directly replace the HS5D R7 without circuit modifications?

A: Yes. The US5DC-HF is a parametric equivalent with identical electrical specifications (200 V, 5 A, 1 V forward voltage, 50 ns recovery time) and identical DO-214AB (SMC) package. No circuit board redesign or component layout changes are required.

Q: What are the limitations of using RS3D-M3/9AT as a substitute?

A: The RS3D-M3/9AT operates at 3 A average rectified current, compared to the 5 A rating of the HS5D R7. This substitute is applicable only in circuits where peak and average current demands do not exceed 3 A. Forward voltage is also higher at 1.3 V @ 2.5 A, which may affect power dissipation and thermal performance. Reverse recovery time is 150 ns versus 50 ns, which may impact switching characteristics in high-frequency applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both US5DC-HF and RS3D-M3/9AT are ROHS3 compliant, matching the compliance status of the HS5D R7. All parts carry MSL 1 (Unlimited) moisture sensitivity classification and are unaffected by REACH regulations.

Q: Do the substitute parts operate across the same temperature range?

A: Yes. Both US5DC-HF and RS3D-M3/9AT operate across the identical junction temperature range of -55°C to 150°C as the HS5D R7.

Q: What is the difference in reverse leakage current between the main part and substitutes?

A: The HS5D R7 exhibits 10 µA @ 200 V reverse leakage. The US5DC-HF shows lower leakage at 5 µA @ 200 V. The RS3D-M3/9AT specifies 10 µA @ 100 V, which is measured at a lower reverse voltage and therefore not directly comparable at the 200 V rating.

Q: How do the junction capacitance values compare?

A: The HS5D R7 has 80 pF @ 4V, 1MHz. The US5DC-HF has 50 pF @ 4V, 1MHz. The RS3D-M3/9AT has 44 pF @ 4V, 1MHz. Lower capacitance in the substitutes may improve high-frequency switching performance.

Q: Are there packaging differences between the main part and substitutes?

A: No. All three parts use identical DO-214AB (SMC) surface mount packaging. Mechanical compatibility is maintained across all substitutes.

Q: What is the product availability status of each part?

A: The HS5D R7 is discontinued at DiGi Electronics. Both US5DC-HF and RS3D-M3/9AT maintain active product status, ensuring continued availability and supply chain support.
