HS5D R7G Equivalent & Substitute Parts

Part Overview

The HS5D R7G 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 part features fast recovery characteristics with a 50 ns reverse recovery time and operates across a junction temperature range of -55°C to 150°C. The HS5D R7G has been discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitute parts for the HS5D R7G are classified into two functional categories based on electrical parameter compatibility:

Category A: Direct Current Rating Equivalents (5 A) Parts maintaining the 5 A average rectified current specification with 200 V reverse voltage rating. These components provide direct functional replacement without circuit redesign.

Category B: Reduced Current Rating Alternatives (3 A) Parts rated for 3 A average rectified current with 200 V reverse voltage. These substitutes are suitable for applications where the circuit design permits operation at the lower current rating, or where the actual load current does not exceed 3 A despite the original design specification.

Substitution eligibility is determined by the following parameters:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 200 V
Package / Case: Must be DO-214AB (SMC) or compatible surface mount package
Speed Classification: Must be Fast Recovery (≤ 500ns, > 200mA)
RoHS Status: Must be ROHS3 Compliant
Mounting Type: Must be Surface Mount

Engineering Selection Recommendations

Direct Replacement (5 A Current Rating)

CGRC503-G from Comchip Technology is the only active substitute maintaining the 5 A average rectified current specification. This part is ROHS3 compliant and housed in the DO-214AB (SMC) package, providing mechanical and electrical compatibility. The forward voltage specification of 1.15 V @ 5 A is marginally higher than the original 1 V @ 5 A, and the recovery speed is classified as Standard Recovery (>500ns) rather than Fast Recovery. These differences require circuit-level evaluation to confirm suitability for the intended application.

Alternative Substitutes (3 A Current Rating)

For applications where the circuit design permits operation at 3 A average rectified current, multiple active alternatives are available:

CURC303-G (Comchip Technology) maintains fast recovery characteristics (50 ns trr) and forward voltage of 1 V @ 3 A, providing electrical performance closely aligned with the original HS5D R7G specifications.

ES3D-13-F (Diodes Incorporated) offers superior reverse recovery time (25 ns) and lower forward voltage (900 mV @ 3 A), with high inventory availability (45,182 pcs). This part is ROHS3 compliant and MSL 1 rated.

MURS320 series variants (Diodes Incorporated and Vishay General Semiconductor - Diodes Division) provide consistent 200 V / 3 A ratings with forward voltages of 875 mV @ 3 A and reverse recovery times of 25 ns to 35 ns. Multiple packaging options and tape configurations are available across this series.

All substitute parts listed are ROHS3 compliant, MSL 1 rated, and maintain surface mount DO-214AB (SMC) packaging with the exception of ES3DB-13-F, which uses DO-214AA (SMB) packaging and requires PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can CGRC503-G be used as a direct replacement for HS5D R7G?

A: CGRC503-G maintains the 5 A current rating and 200 V reverse voltage specification in the same DO-214AB (SMC) package. However, the forward voltage is specified at 1.15 V @ 5 A compared to 1 V @ 5 A for the original part, and recovery speed is Standard (>500ns) rather than Fast (≤500ns). Circuit validation is required to confirm compatibility.

Q: What is the difference between Category A and Category B substitutes?

A: Category A substitutes (CGRC503-G) maintain the original 5 A average rectified current rating. Category B substitutes are rated for 3 A average rectified current. Selection depends on whether the circuit design can operate at the lower current rating or if the actual load current does not exceed 3 A.

Q: Why is ES3DB-13-F listed if it uses a different package?

A: ES3DB-13-F uses DO-214AA (SMB) packaging instead of DO-214AB (SMC). While electrically equivalent to other 3 A substitutes, this part requires PCB layout modification and is not a direct mechanical replacement. It is included for reference in applications where package change is feasible.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode exhibits fast recovery characteristics with reverse recovery time not exceeding 500 nanoseconds when the forward current exceeds 200 milliamps. This classification affects switching performance in high-frequency applications.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original HS5D R7G.

Q: Which substitute offers the lowest forward voltage drop?

A: MURS320-13-F specifies 875 mV @ 3 A forward voltage, the lowest among all listed substitutes. ES3D-13-F and related variants specify 900 mV @ 3 A. These lower forward voltages reduce power dissipation compared to the original 1 V @ 5 A specification.

Q: What is the difference between MURS320 variants (13-F, E3/57T, E3/9AT, M3/57T, M3/9AT)?

A: All MURS320 variants share identical electrical specifications (200 V, 3 A, 875 mV Vf, 25-35 ns trr). Differences lie in packaging configuration and tape format. The suffix designates the specific tape and reel configuration or cut tape format. Selection depends on procurement and assembly requirements.

Q: Can I use a 3 A rated diode in a circuit designed for 5 A?

A: Substitution of a 3 A rated diode in a 5 A circuit is permissible only if the actual operating current does not exceed 3 A. The circuit must be analyzed to confirm that peak and average currents remain within the lower rating. Exceeding the rated current will result in excessive heat generation and component failure.
