HS5F R7G Equivalent & Substitute Parts

Part Overview

The HS5F R7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 300 V DC reverse voltage and 5 A average rectified current in a DO-214AB (SMC) surface mount package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The HS5F R7G operates across a junction temperature range of -55°C to 150°C with fast recovery characteristics (≤500 ns) and a reverse recovery time of 50 ns, making it suitable for general-purpose rectification applications requiring moderate current capacity.

Substitute Part Grouping Explanation

Substitution of the HS5F R7G is determined by the following critical parameters:

Parametric Equivalents share identical electrical specifications: 300 V reverse voltage, 5 A average rectified current, 1 V forward voltage at 5 A, 50 ns reverse recovery time, and DO-214AB package. The HS5F V7G meets all these criteria with identical performance characteristics.

Similar Substitutes operate at the same 300 V reverse voltage and DO-214AB package but with reduced current capacity (3 A instead of 5 A). These include ES3F series diodes from Vishay General Semiconductor and UFS330 series diodes from Microchip Technology. These parts are suitable for applications where the 5 A current requirement can be reduced or where multiple devices can be paralleled.

Current-Matched Alternatives maintain the 5 A current rating at 300 V but may originate from different manufacturers. The UFS530J/TR13 from Microchip Technology provides 5 A capacity with slightly higher forward voltage (1.2 V @ 5 A) and extended operating temperature range (-55°C to 175°C).

All substitute parts maintain the DO-214AB surface mount package, fast recovery speed characteristic (≤500 ns), and 50 ns reverse recovery time. Substitution is valid only when the application circuit can accommodate the specified electrical parameters of the selected alternative.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent)

The HS5F V7G is a parametric equivalent to the HS5F R7G, offering identical electrical performance and package specifications. Both parts are discontinued at DiGi Electronics but maintain ROHS3 compliance. The HS5F V7G is available in higher inventory (2356 pcs) compared to the HS5F R7G (761 pcs), making it the preferred choice for immediate procurement when identical specifications are required.

Active Alternatives with Reduced Current Rating

The Vishay ES3F series (ES3F-E3/57T, ES3F-E3/9AT, ES3F-M3/57T, ES3F-M3/9AT) and ES3FHE3 automotive-grade variants provide 3 A current capacity at 300 V with identical reverse recovery time and package. These parts are active products with ROHS3 compliance. The ES3FHE3_A/H and ES3FHE3_A/I variants include AEC-Q101 automotive qualification. Selection of these parts is appropriate for applications where the circuit design permits operation at 3 A or where current sharing through parallel devices is implemented.

Current-Matched Alternative with Extended Temperature Range

The Microchip UFS530J/TR13 maintains the 5 A current rating at 300 V with extended operating temperature range (-55°C to 175°C) compared to the HS5F R7G (-55°C to 150°C). Forward voltage is slightly elevated at 1.2 V @ 5 A. This part is active and available (1162 pcs inventory) but carries RoHS non-compliance status. Selection is appropriate for high-temperature applications where the additional thermal margin is required and RoHS compliance is not mandated.

RoHS-Compliant 3 A Alternative

The Microchip UFS330JE3/TR13 provides 3 A capacity at 300 V with ROHS3 compliance and extended temperature range (-55°C to 175°C). This part bridges the gap between the discontinued HS5F R7G and active alternatives, offering compliance certification with moderate current capacity.

Frequently Asked Questions (FAQ)

Q: Can the HS5F V7G directly replace the HS5F R7G?

A: Yes. The HS5F V7G is a parametric equivalent with identical voltage rating (300 V), current capacity (5 A), forward voltage (1 V @ 5 A), reverse recovery time (50 ns), and DO-214AB package. Both parts are discontinued at DiGi Electronics but maintain identical electrical and mechanical specifications.

Q: What is the difference between the HS5F R7G and ES3F series diodes?

A: The primary difference is current capacity. The HS5F R7G is rated for 5 A average rectified current, while ES3F series diodes are rated for 3 A. Both maintain 300 V reverse voltage, 50 ns reverse recovery time, and DO-214AB package. Forward voltage is slightly higher in the ES3F series (1.1 V @ 3 A versus 1 V @ 5 A). ES3F parts are active products with current availability.

Q: Can I use a 3 A diode in place of a 5 A diode?

A: Substitution of a 3 A diode for a 5 A application is valid only if the circuit design ensures that the actual operating current does not exceed 3 A. If the application requires 5 A continuous current, a 3 A device will exceed its current rating and result in thermal stress and potential failure. Parallel connection of multiple 3 A devices can achieve 5 A capacity if circuit topology permits.

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

A: The DO-214AB (also designated SMC) is a surface mount package with standardized dimensions and lead configuration. All substitute parts listed maintain this package specification, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. No board redesign is required when substituting between parts with identical DO-214AB packaging.

Q: Are the Vishay ES3FHE3 automotive-grade diodes suitable for non-automotive applications?

A: Yes. The ES3FHE3_A/H and ES3FHE3_A/I variants include AEC-Q101 automotive qualification, indicating enhanced reliability and screening. These parts are suitable for any application requiring 3 A at 300 V, including non-automotive designs. Automotive qualification does not restrict use to automotive applications.

Q: What is the difference between RoHS-compliant and RoHS non-compliant parts?

A: ROHS3-compliant parts (HS5F R7G, HS5F V7G, ES3F series, UFS330JE3/TR13) meet Restriction of Hazardous Substances directives and contain no lead, mercury, cadmium, or other restricted substances. RoHS non-compliant parts (UFS530J/TR13, UFS330J/TR13) may contain restricted substances. Selection depends on regulatory requirements for the end application and geographic market.

Q: Can the UFS530J/TR13 replace the HS5F R7G despite RoHS non-compliance?

A: The UFS530J/TR13 provides identical 5 A current capacity and 300 V voltage rating with extended temperature range (-55°C to 175°C). Substitution is electrically valid but introduces RoHS non-compliance. Selection is appropriate only for applications where RoHS compliance is not required and the extended temperature range provides design benefit.

Q: What does reverse recovery time (trr) indicate?

A: Reverse recovery time is the interval required for a diode to transition from forward conduction to reverse blocking when the applied voltage reverses. All listed parts maintain 50 ns reverse recovery time, indicating identical switching speed characteristics. This parameter is critical for high-frequency rectification and switching applications.

Q: How does forward voltage affect circuit design?

A: Forward voltage (Vf) represents the voltage drop across the diode during forward conduction. The HS5F R7G exhibits 1 V @ 5 A, while ES3F series diodes exhibit 1.1 V @ 3 A. Higher forward voltage results in increased power dissipation and heat generation. Circuit designs must account for the specific forward voltage of the selected device to ensure adequate thermal management and power supply regulation.
