HS5D M6G Equivalent & Substitute Parts

Part Overview

The HS5D M6G 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 M6G 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 M6G are classified into two functional categories based on electrical parameter compatibility:

Category A: Direct Current Rating Substitutes (5 A) Parts maintaining the 5 A average rectified current specification. The CGRC503-G from Comchip Technology is the only substitute in this category. This part matches the 200 V reverse voltage and 5 A current rating, though it operates with standard recovery speed (>500ns) rather than fast recovery, and exhibits a higher forward voltage drop of 1.15 V at 5 A compared to the 1 V specification of the HS5D M6G.

Category B: Reduced Current Rating Substitutes (3 A) Parts rated for 3 A average rectified current, which is lower than the original 5 A specification. These include CURC303-G, ER3D-TP, ES3D-13-F, ES3DB-13-F, MURS320-13-F, MURS320-E3/57T, MURS320-E3/9AT, MURS320-M3/57T, and MURS320-M3/9AT. All maintain the 200 V reverse voltage rating and DO-214AB (SMC) package format. These parts feature fast recovery characteristics with reverse recovery times ranging from 25 ns to 35 ns, and forward voltage drops between 875 mV and 1 V at their respective 3 A current ratings.

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
Current - Average Rectified (Io): Must equal or exceed application requirement
Speed: Fast Recovery or Standard Recovery acceptable based on circuit requirements
Operating Temperature Range: Must encompass application operating conditions
RoHS and MSL Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Engineering Selection Recommendations

For applications requiring 5 A current capacity: The CGRC503-G from Comchip Technology is the only substitute maintaining the 5 A average rectified current rating. This part is currently active in production and ROHS3 compliant with MSL 1 rating. The primary electrical difference is the forward voltage specification of 1.15 V at 5 A compared to 1 V for the HS5D M6G, and the recovery speed classification as standard recovery (>500ns) rather than fast recovery. Circuit designs sensitive to forward voltage drop or requiring fast recovery characteristics must account for these differences.

For applications tolerating 3 A current capacity: Multiple active substitutes are available with 3 A ratings. The MURS320 series variants (MURS320-13-F, MURS320-E3/57T, MURS320-E3/9AT, MURS320-M3/57T, MURS320-M3/9AT) from Vishay General Semiconductor offer extended operating temperature ranges (-65°C to 175°C) and lower forward voltage drops (875 mV at 3 A). The ES3D-13-F from Diodes Incorporated provides 900 mV forward voltage at 3 A with a 25 ns reverse recovery time. The ER3D-TP from Micro Commercial Co offers 950 mV forward voltage at 3 A with a 35 ns reverse recovery time and extended upper temperature rating (175°C). All candidates maintain ROHS3 compliance and MSL 1 rating.

For applications with standard recovery speed tolerance: The CGRC503-G operates with standard recovery speed (>500ns) and is suitable for applications where fast recovery is not a circuit requirement.

For applications requiring fast recovery characteristics: All 3 A rated substitutes (CURC303-G, ER3D-TP, ES3D-13-F, MURS320 variants) maintain fast recovery speed specifications with reverse recovery times between 25 ns and 50 ns.

Frequently Asked Questions (FAQ)

Q: Can the HS5D M6G be directly replaced with a 3 A rated substitute? A: Direct replacement depends on circuit current requirements. If the application draws 3 A or less, 3 A rated substitutes are electrically compatible. If the application requires 5 A capacity, only the CGRC503-G maintains this current rating. Circuit analysis must confirm that peak and average current demands do not exceed the substitute part's rating.

Q: What is the significance of fast recovery versus standard recovery speed? A: Fast recovery diodes (≤500ns reverse recovery time) are used in high-frequency switching applications and power factor correction circuits where switching speed affects efficiency and electromagnetic interference. Standard recovery diodes (>500ns) are suitable for lower-frequency applications such as general rectification and power supply filtering. The CGRC503-G operates with standard recovery speed, while all 3 A substitutes maintain fast recovery characteristics.

Q: Are all substitute parts pin-compatible with the HS5D M6G? A: All listed substitutes use the DO-214AB (SMC) surface mount package, which provides identical pin configuration and footprint compatibility. The ES3DB-13-F uses the DO-214AA (SMB) package, which has a different footprint and is not pin-compatible. Verify PCB layout compatibility before selecting this alternative.

Q: How do forward voltage differences affect circuit performance? A: Forward voltage drop directly impacts power dissipation and voltage regulation. The HS5D M6G specifies 1 V at 5 A. The CGRC503-G specifies 1.15 V at 5 A, resulting in 15% higher voltage drop. The 3 A substitutes range from 875 mV to 1 V at their respective 3 A ratings. In precision rectification or low-voltage applications, these differences may require circuit recalculation for voltage regulation and thermal management.

Q: What is the impact of reverse recovery time on circuit design? A: Reverse recovery time (trr) affects switching transients and electromagnetic interference in switching applications. The HS5D M6G specifies 50 ns. The 3 A substitutes offer faster recovery times (25 ns to 35 ns), which reduces switching losses and EMI. The CGRC503-G does not specify trr, indicating standard recovery characteristics. Applications sensitive to switching transients benefit from faster recovery times.

Q: Are all substitutes suitable for the full operating temperature range of the HS5D M6G? A: The HS5D M6G operates from -55°C to 150°C. The CGRC503-G and CURC303-G specify only a maximum junction temperature of 150°C without a minimum specification. The ER3D-TP, MURS320 variants, and ES3D-13-F provide full temperature range specifications. For applications requiring operation below 0°C, verify that the selected substitute specifies a minimum junction temperature of -55°C or lower.

Q: What compliance certifications are maintained across all substitutes? A: All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the HS5D M6G specifications. All parts carry EAR99 ECCN classification and REACH Unaffected status. These certifications ensure regulatory compliance for commercial and industrial applications.

Q: Which substitute offers the best overall performance match to the HS5D M6G? A: No single 3 A substitute exactly matches all HS5D M6G specifications. The CURC303-G from Comchip Technology provides the closest electrical match with identical 1 V forward voltage at its 3 A rating, 50 ns reverse recovery time, and fast recovery speed classification. However, it is limited to 3 A current capacity. For applications requiring 5 A capacity, the CGRC503-G is the only available option, with the trade-off of higher forward voltage and standard recovery speed.
