RS1GLHM2G Equivalent & Substitute Parts

Part Overview

The RS1GLHM2G is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. This surface mount diode is rated for 400V DC reverse voltage with 800mA average rectified current and features a 150ns reverse recovery time. The device is housed in a Sub SMA (DO-219AB) package and is qualified to AEC-Q101 automotive standards. This part is currently active in production with 1121 pieces in stock. Substitute parts are identified based on matching electrical performance parameters and compatible mounting technologies to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS1GLHM2G are identified based on the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 400V minimum
• Current - Average Rectified (Io): 800mA or higher
• Voltage - Forward (Vf) (Max): 1.3V or lower at rated current
• Reverse Recovery Time (trr): 150ns or faster
• Current - Reverse Leakage @ Vr: 5µA or lower at 400V
• Capacitance @ Vr, F: 10pF or lower at 4V, 1MHz
• Operating Temperature Range: -55°C to 150°C minimum

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts must maintain all electrical parameters at or above the main part specifications and support surface mount assembly. Package variations (Sub SMA vs. SOD-123FL) are permitted when electrical performance is equivalent or superior.

Engineering Selection Recommendations

RS1GL (SMC Diode Solutions)

The RS1GL is a parametric equivalent with superior current rating (1A vs. 800mA). All electrical parameters match or exceed the RS1GLHM2G specification. This part is manufactured by SMC Diode Solutions and is ROHS3 compliant with MSL 1 rating. The primary difference is the package format (SOD-123F vs. Sub SMA DO-219AB), which requires PCB layout modification. This substitute is suitable for applications where package footprint change is acceptable and higher current capacity provides design margin. Inventory availability is significantly higher at 1,061,300 pieces.

RS1GL R3G (Taiwan Semiconductor Corporation)

The RS1GL R3G is an exact parametric and package equivalent to the RS1GLHM2G, manufactured by the same supplier (Taiwan Semiconductor Corporation). All electrical specifications are identical, and the DO-219AB package format matches the main part. This substitute is supplied in Tape & Reel (TR) packaging format versus the main part's standard packaging. Both parts carry identical compliance certifications (ROHS3, AEC-Q101 automotive qualification, REACH Unaffected, EAR99 ECCN). This substitute provides direct compatibility with no design modifications required. Inventory is available at 1,036 pieces.

Frequently Asked Questions (FAQ)

Q: Can RS1GL be used as a direct replacement for RS1GLHM2G?

A: The RS1GL is electrically equivalent with superior current rating (1A vs. 800mA). However, the package format differs (SOD-123F vs. Sub SMA DO-219AB), requiring PCB footprint modification. Electrical performance is fully compatible.

Q: What is the difference between RS1GL R3G and RS1GLHM2G?

A: The RS1GL R3G is a parametric and package equivalent to RS1GLHM2G. Both use the DO-219AB Sub SMA package and identical electrical specifications. The primary difference is packaging format: RS1GL R3G is supplied in Tape & Reel (TR) while RS1GLHM2G uses standard packaging. Both are manufactured by Taiwan Semiconductor Corporation.

Q: Are all substitute parts automotive qualified?

A: The RS1GLHM2G and RS1GL R3G carry AEC-Q101 automotive qualification. The RS1GL from SMC Diode Solutions does not list AEC-Q101 qualification in the provided specifications. Verify automotive qualification requirements with your application specifications.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: Voltage - DC Reverse (Vr) of 400V minimum, Current - Average Rectified (Io) of 800mA or higher, Voltage - Forward (Vf) of 1.3V or lower, Reverse Recovery Time (trr) of 150ns or faster, Current - Reverse Leakage of 5µA or lower at 400V, and Capacitance of 10pF or lower at 4V, 1MHz. All substitute parts meet or exceed these parameters.

Q: Does package format affect electrical performance?

A: Package format (Sub SMA DO-219AB vs. SOD-123F) does not affect the electrical performance specifications listed. However, package selection impacts PCB layout, thermal management, and assembly compatibility. Verify PCB design compatibility before selecting a substitute with different package format.

Q: What is the moisture sensitivity level for these parts?

A: All three parts (RS1GLHM2G, RS1GL, and RS1GL R3G) carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: Are these parts RoHS compliant?

A: All three parts are ROHS3 compliant. The RS1GLHM2G and RS1GL R3G are REACH Unaffected. The RS1GL is REACH Affected. Verify REACH compliance requirements for your application.
