Engineering Selection Recommendations

S1DL RVG is a parametric equivalent to the S1DL M2G, manufactured by Taiwan Semiconductor Corporation. Both parts share identical electrical specifications and operating temperature ranges. The primary distinction is packaging format: S1DL M2G is supplied in standard packaging while S1DL RVG is supplied in Tape & Reel (TR) format. Both are ROHS3 compliant and Active product status. Selection between these two is determined by procurement and assembly requirements rather than electrical performance.

VS-1EFH02-M3/I is a similar manufacturer part from Vishay General Semiconductor - Diodes Division. This part maintains the 200 V voltage rating and 1 A current rating in the DO-219AB package. Differences include significantly faster recovery time (16 ns versus 1.8 µs), lower forward voltage (930 mV versus 1.1 V), and lower reverse leakage current (2 µA versus 5 µA). The operating temperature range extends to -65°C. This part is ROHS3 compliant and Active product status.

VS-2EFH02HM3/I is a similar manufacturer part from Vishay General Semiconductor - Diodes Division with a higher current rating of 2 A. This part maintains the 200 V voltage rating in the DO-219AB package. Differences include faster recovery time (25 ns versus 1.8 µs), lower forward voltage (950 mV versus 1.1 V), and lower reverse leakage current (2 µA versus 5 µA). This part includes automotive qualification (AEC-Q101) and extended operating temperature range (-65°C ~ 175°C). ROHS3 compliant and Active product status.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and Active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can S1DL RVG be used as a direct replacement for S1DL M2G?

A: Yes. S1DL RVG is a parametric equivalent with identical electrical specifications, voltage rating (200 V), current rating (1 A), forward voltage (1.1 V @ 1 A), reverse recovery time (1.8 µs), and operating temperature range (-55°C ~ 175°C). The difference is packaging format: S1DL RVG is supplied in Tape & Reel format while S1DL M2G is supplied in standard packaging. Both are in DO-219AB Sub SMA package and are ROHS3 compliant.

Q: What are the key differences between S1DL M2G and VS-1EFH02-M3/I?

A: Both parts share the same 200 V voltage rating, 1 A current rating, and DO-219AB package. VS-1EFH02-M3/I has significantly faster recovery time (16 ns versus 1.8 µs), lower forward voltage (930 mV versus 1.1 V), and lower reverse leakage current (2 µA versus 5 µA). VS-1EFH02-M3/I also has an extended lower operating temperature limit (-65°C versus -55°C). Both are ROHS3 compliant and Active status.

Q: Is VS-2EFH02HM3/I suitable for applications requiring 1 A current?

A: VS-2EFH02HM3/I is rated for 2 A average rectified current, which exceeds the 1 A requirement of the S1DL M2G. This part maintains the 200 V voltage rating and DO-219AB package. The higher current rating provides design margin. Forward voltage is 950 mV @ 2 A, recovery time is 25 ns, and reverse leakage is 2 µA @ 200 V. This part includes automotive qualification (AEC-Q101) and is ROHS3 compliant.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts (S1DL RVG, VS-1EFH02-M3/I, and VS-2EFH02HM3/I) are supplied in DO-219AB Sub SMA package with surface mount mounting type. Packaging format differs: S1DL M2G and S1DL RVG differ in tape format, while Vishay parts are supplied in Tape & Reel format.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts listed (S1DL M2G, S1DL RVG, VS-1EFH02-M3/I, and VS-2EFH02HM3/I) are ROHS3 compliant, REACH unaffected, and maintain Active product status. VS-2EFH02HM3/I additionally includes automotive qualification per AEC-Q101.

Q: What is the impact of faster recovery time in Vishay parts?

A: Vishay parts (VS-1EFH02-M3/I with 16 ns and VS-2EFH02HM3/I with 25 ns) have significantly faster recovery times compared to S1DL M2G (1.8 µs). Faster recovery time reduces switching losses and heat generation in high-frequency applications. This characteristic is determined by the FRED Pt® technology series used in Vishay parts versus standard recovery technology in Taiwan Semiconductor parts.
