RSFDL RTG Equivalent & Substitute Parts

Part Overview

The RSFDL RTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 500 mA average rectified current. The device features fast recovery characteristics with a reverse recovery time of 150 ns and is packaged in the DO-219AB (Sub SMA) surface mount configuration. The RSFDL RTG maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary to address inventory availability, packaging format requirements, and design flexibility across manufacturing environments. Alternative part numbers provide identical or enhanced electrical performance while maintaining compatibility with the DO-219AB package footprint.

Substitute Part Grouping Explanation

Substitution of the RSFDL RTG is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 500 mA minimum
Package / Case: DO-219AB
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature Range: Must encompass -55°C to 150°C minimum

Parametric Equivalent Parts maintain identical electrical specifications and are direct functional replacements:

RSFDL (Tape & Reel packaging variant)
RSFDL R3G (Cut Tape packaging variant)

Similar Parts meet or exceed the primary substitution criteria but may exhibit variations in secondary parameters such as forward voltage, reverse leakage current, or reverse recovery time:

RS07D-GS08 (Vishay General Semiconductor)
VS-1EFH02-M3/I (Vishay General Semiconductor, 1A rated)
VS-2EFH02HM3/I (Vishay General Semiconductor, 2A rated)

All substitute parts maintain DO-219AB package compatibility, surface mount configuration, and RoHS3 compliance.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

RSFDL R3G is the recommended parametric equivalent for new designs. It maintains identical electrical specifications to the RSFDL RTG, is supplied in Cut Tape (CT) packaging format, and carries Active product status. This part is suitable for applications requiring the exact performance profile of the original RSFDL RTG.

RSFDL (Tape & Reel variant) is a parametric equivalent with higher inventory availability (13,300 pcs) but carries "Not For New Designs" product status. This part is appropriate for sustaining production of existing designs or applications where new design qualification is not required.

For Enhanced Performance (Similar Parts):

RS07D-GS08 (Vishay) provides equivalent reverse voltage and current ratings with improved forward voltage characteristics (1.15 V @ 700 mA versus 1.3 V @ 500 mA). This part includes AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade reliability. Reverse leakage current is higher (10 µA @ 200 V versus 5 µA @ 200 V).

VS-1EFH02-M3/I (Vishay FRED Pt® series) provides 1 A average rectified current capacity with significantly improved reverse recovery time (16 ns versus 150 ns) and lower reverse leakage current (2 µA @ 200 V). This part is suitable for applications requiring higher current capacity or improved switching performance.

VS-2EFH02HM3/I (Vishay FRED Pt® series) provides 2 A average rectified current capacity with improved reverse recovery time (25 ns versus 150 ns) and lower reverse leakage current (2 µA @ 200 V). This part includes AEC-Q101 automotive qualification and is suitable for high-current applications requiring automotive-grade reliability.

All substitute parts maintain RoHS3 compliance and DO-219AB package compatibility.

Frequently Asked Questions (FAQ)

Q: Can RSFDL R3G be used as a direct replacement for RSFDL RTG?

A: Yes. RSFDL R3G is a parametric equivalent with identical electrical specifications (200 V reverse voltage, 500 mA average rectified current, 1.3 V forward voltage @ 500 mA, 150 ns reverse recovery time). The primary difference is packaging format: RSFDL R3G is supplied in Cut Tape (CT) format while RSFDL RTG is supplied in standard packaging. Both use the DO-219AB package footprint and are surface mount compatible.

Q: What is the difference between RSFDL and RSFDL R3G?

A: RSFDL and RSFDL R3G are parametric equivalents with identical electrical specifications. The difference is packaging format: RSFDL is supplied in Tape & Reel (TR) format, while RSFDL R3G is supplied in Cut Tape (CT) format. Additionally, RSFDL carries "Not For New Designs" status, while RSFDL R3G is Active. For new designs, RSFDL R3G is the appropriate selection.

Q: Can RS07D-GS08 replace RSFDL RTG?

A: RS07D-GS08 meets the primary substitution criteria (200 V reverse voltage, 500 mA minimum current capacity, DO-219AB package, fast recovery speed). However, it exhibits different secondary parameters: forward voltage is lower (1.15 V @ 700 mA versus 1.3 V @ 500 mA), and reverse leakage current is higher (10 µA @ 200 V versus 5 µA @ 200 V). RS07D-GS08 includes AEC-Q101 automotive qualification. Substitution is acceptable where these parameter variations are within application tolerance.

Q: When should VS-1EFH02-M3/I or VS-2EFH02HM3/I be used instead of RSFDL RTG?

A: VS-1EFH02-M3/I (1 A rated) and VS-2EFH02HM3/I (2 A rated) are suitable when applications require higher current capacity than 500 mA. Both parts provide significantly improved reverse recovery time (16 ns and 25 ns respectively versus 150 ns) and lower reverse leakage current (2 µA @ 200 V versus 5 µA @ 200 V). These parts are appropriate for high-frequency switching applications or designs requiring enhanced performance characteristics. VS-2EFH02HM3/I includes AEC-Q101 automotive qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RSFDL, RSFDL R3G, RS07D-GS08, VS-1EFH02-M3/I, VS-2EFH02HM3/I) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Do all substitute parts use the same DO-219AB package?

A: Yes. All substitute parts use the DO-219AB (Sub SMA / SMF) package configuration and are surface mount compatible. PCB footprint compatibility is maintained across all listed parts.

Q: What is the operating temperature range for substitute parts?

A: RSFDL RTG, RSFDL, and RSFDL R3G operate from -55°C to 150°C junction temperature. RS07D-GS08 operates from -55°C to 150°C. VS-1EFH02-M3/I and VS-2EFH02HM3/I operate from -65°C to 175°C, providing extended low-temperature and high-temperature capability.
