Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS5G V7G is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 5 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Secondary Electrical Parameters (Allowable Variation):

• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 5 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns (baseline; 150 ns acceptable within fast recovery classification)
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V (5 µA acceptable as improved specification)
• Capacitance @ Vr, F: 80 pF @ 4V, 1MHz (50 pF acceptable as improved specification)

All identified substitute parts maintain the critical matching parameters and operate within the allowable variation range for secondary electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: HS5G (Taiwan Semiconductor Corporation)

The HS5G is the direct active equivalent to the discontinued HS5G V7G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, including reverse recovery time of 50 ns and reverse leakage current of 10 µA @ 400 V. The HS5G maintains active product status with 3861 units in stock, ensuring supply continuity. This part is the preferred substitution path for direct replacement applications.

Secondary Recommendations: US5G-TP (Micro Commercial Co) and US5GC-HF (Comchip Technology)

Both US5G-TP and US5GC-HF meet all critical electrical and mechanical parameters. US5G-TP offers the highest inventory availability at 6967 units and matches the HS5G V7G reverse recovery time specification of 50 ns. US5GC-HF provides improved reverse leakage current (5 µA) and reduced capacitance (50 pF), with 932 units available. Both parts are ROHS3 compliant and operate across the required temperature range.

Alternative Recommendation: RS5GC-HF (Comchip Technology)

The RS5GC-HF operates within the fast recovery classification with a reverse recovery time of 150 ns, which remains within the specified ≤ 500ns fast recovery range. This part features improved reverse leakage current (5 µA) and reduced capacitance (50 pF). With 635 units in stock, RS5GC-HF is suitable for applications where the extended reverse recovery time does not impact circuit performance.

Compliance Verification

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the HS5G directly replace the HS5G V7G in all applications?

A: Yes. The HS5G is manufactured by the same supplier (Taiwan Semiconductor Corporation) and maintains identical electrical specifications for voltage rating (400 V), current rating (5 A), reverse recovery time (50 ns), and reverse leakage current (10 µA @ 400 V). The parts are electrically and mechanically interchangeable.

Q: What is the difference between the HS5G and US5G-TP?

A: Both parts share identical critical specifications: 400 V reverse voltage, 5 A current rating, 50 ns reverse recovery time, and 10 µA reverse leakage current. The primary difference is manufacturer (Taiwan Semiconductor Corporation versus Micro Commercial Co). US5G-TP does not specify capacitance, whereas HS5G specifies 80 pF @ 4V, 1MHz. Both are surface mount DO-214AB packages with identical temperature ratings.

Q: Why does RS5GC-HF have a 150 ns reverse recovery time while others specify 50 ns?

A: RS5GC-HF is classified as a fast recovery diode with reverse recovery time ≤ 500ns, which encompasses both 50 ns and 150 ns specifications. The 150 ns specification remains within the fast recovery classification and is acceptable for general-purpose rectification applications. Applications requiring the fastest switching performance should prioritize parts with 50 ns reverse recovery time.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (HS5G, RS5GC-HF, US5G-TP, and US5GC-HF) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and regulatory requirements.

Q: What is the significance of the DO-214AB (SMC) package designation?

A: DO-214AB is the industry-standard surface mount package for general-purpose rectifier diodes in this current and voltage class. All substitute parts use this identical package, ensuring mechanical compatibility with existing PCB layouts, solder reflow profiles, and automated assembly equipment. No board redesign or assembly process modification is required.

Q: Which substitute part offers the best availability?

A: US5G-TP (Micro Commercial Co) offers the highest inventory availability at 6967 units in stock, followed by HS5G at 3861 units. Both parts maintain identical reverse recovery time (50 ns) and reverse leakage current (10 µA @ 400 V) specifications.

Q: Can I use US5GC-HF or RS5GC-HF if the HS5G is unavailable?

A: Yes. Both Comchip Technology parts (US5GC-HF and RS5GC-HF) meet all critical electrical and mechanical parameters. US5GC-HF matches the 50 ns reverse recovery time specification. RS5GC-HF operates with 150 ns reverse recovery time, which remains within the fast recovery classification. Both parts are suitable alternatives when primary options are unavailable.

Q: What is the difference between reverse leakage current specifications of 10 µA and 5 µA?

A: Both specifications are acceptable for general-purpose rectification. The 5 µA specification (found in RS5GC-HF and US5GC-HF) represents improved leakage performance compared to the 10 µA specification. For most applications, this difference is not functionally significant. Applications with stringent leakage requirements may benefit from the lower 5 µA specification.

Q: Are there any temperature rating differences among the substitute parts?

A: No. All substitute parts maintain identical operating temperature range of -55°C to 150°C junction temperature, ensuring compatibility across the full specified thermal operating envelope.
