RS1GLHRVG Equivalent & Substitute Parts

Part Overview

The RS1GLHRVG is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400V DC reverse voltage and 800mA average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is fully compliant with automotive qualification standards (AEC-Q101) and RoHS3 requirements.

Substitute parts are identified based on matching or exceeding the electrical performance parameters while maintaining compatibility with the specified operating conditions. Alternatives are selected when the primary part requires extended lead times, when packaging variants are needed for specific assembly processes, or when higher current ratings provide design margin for the same voltage class.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RS1GLHRVG is based on the following critical parameters:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 400V to ensure safe operation in the intended circuit.

Current Rating: Substitute parts must support a minimum average rectified current of 800mA. Parts with higher current ratings (such as 1A) are acceptable as they provide additional design margin without compromising circuit function.

Recovery Characteristics: All substitutes must maintain fast recovery speed classification (≤ 500ns for currents > 200mA) with a reverse recovery time of 150ns to preserve switching performance and minimize switching losses.

Forward Voltage: Forward voltage drop must not exceed 1.3V at the rated current to maintain thermal and efficiency characteristics.

Leakage Current: Reverse leakage current must not exceed 5µA at 400V to ensure acceptable standby power consumption.

Temperature Range: Operating junction temperature range must span -55°C to 150°C to support the full automotive operating environment.

Compliance: All substitutes must maintain RoHS3 compliance and automotive-grade qualification where applicable.

Package Compatibility: Substitutes may differ in package type (DO-219AB Sub SMA versus SOD-123F) and tape format (Cut Tape, Digi-Reel, or Tape & Reel), provided the surface mount mounting type is preserved.

Parameter Comparison

Engineering Selection Recommendations

RS1GL (SMC Diode Solutions): This substitute provides parametric equivalence with a higher current rating of 1A, offering increased design margin over the 800mA requirement. The part maintains identical voltage, recovery time, and leakage specifications. The primary distinction is the package format: SOD-123F replaces the DO-219AB Sub SMA package. This substitution is suitable when board space permits the SOD-123F footprint or when higher current capacity is required. The part is RoHS3 compliant and maintains the same operating temperature range. Inventory availability is significantly higher (1,061,300 pcs) compared to the main part.

RS1GL R3G (Taiwan Semiconductor Corporation): This substitute is a direct parametric and package equivalent to the RS1GLHRVG, differing only in the tape format (Tape & Reel versus the original packaging specification). Electrical specifications, package type (DO-219AB Sub SMA), and compliance certifications are identical. This substitution is appropriate when Tape & Reel format is required for automated assembly processes. The part maintains AEC-Q101 automotive qualification and RoHS3 compliance. Inventory availability is 1,036 pcs.

Both substitutes maintain Active product status and full compliance with automotive and environmental standards applicable to the main part.

Frequently Asked Questions (FAQ)

Q: Can RS1GL be used as a direct replacement for RS1GLHRVG in the same PCB footprint?

A: No. RS1GL uses SOD-123F package while RS1GLHRVG uses DO-219AB (Sub SMA) package. These packages have different footprints and pin configurations. PCB layout modification is required. RS1GL R3G maintains the identical DO-219AB package and can be used in the same footprint.

Q: What is the advantage of using RS1GL over RS1GLHRVG?

A: RS1GL provides a higher current rating of 1A compared to 800mA, offering additional design margin for the same voltage class. All other electrical parameters remain equivalent. The trade-off is the different package format, which requires PCB redesign.

Q: Are all three parts suitable for automotive applications?

A: RS1GLHRVG and RS1GL R3G carry AEC-Q101 automotive qualification. RS1GL does not list AEC-Q101 qualification in the provided specifications. Verify automotive qualification requirements with the application before selecting RS1GL for automotive designs.

Q: What is the difference between RS1GLHRVG and RS1GL R3G?

A: These parts are electrically and mechanically identical. The only difference is the tape format: RS1GLHRVG uses standard packaging while RS1GL R3G is supplied in Tape & Reel format. Selection depends on assembly process requirements.

Q: Can I use RS1GL R3G if my assembly line requires Cut Tape format?

A: No. RS1GL R3G is supplied only in Tape & Reel format. If Cut Tape format is required, use RS1GLHRVG or verify alternative packaging availability with the supplier.

Q: Do all three parts have the same reverse recovery time?

A: Yes. All three parts (RS1GLHRVG, RS1GL, and RS1GL R3G) have a reverse recovery time of 150ns, ensuring identical switching performance in fast recovery applications.

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

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.

Q: Are these parts RoHS compliant?

A: Yes. RS1GLHRVG and RS1GL R3G are ROHS3 Compliant. RS1GL is also ROHS3 Compliant. All parts meet RoHS3 environmental standards.
