Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1DL RFG are identified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A or greater
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute Classification:

Parametric Equivalent: S1DL RVG differs from the main part only in packaging configuration (Tape & Reel versus standard packaging). All electrical parameters, voltage ratings, current ratings, and thermal specifications are identical. This part is a direct functional equivalent suitable for applications with identical electrical requirements.

Similar Manufacturer Parts: VS-1EFH02-M3/I and VS-2EFH02HM3/I are manufactured by Vishay General Semiconductor - Diodes Division and meet the core voltage and package requirements. These parts exhibit different recovery characteristics and leakage specifications within the same voltage and package class. The VS-2EFH02HM3/I carries automotive qualification (AEC-Q101) and supports higher current ratings (2 A), making it suitable for applications requiring enhanced performance margins or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

S1DL RVG (Parametric Equivalent): This part is a direct functional equivalent to the S1DL RFG with identical electrical specifications and thermal operating range. The distinction is packaging configuration only. Selection of S1DL RVG is appropriate when Tape & Reel packaging is required for automated assembly processes or when inventory sourcing from this configuration is necessary. Both parts maintain Active product status and full RoHS3 compliance.

VS-1EFH02-M3/I (Similar Manufacturer Part): This Vishay part meets the core voltage and current requirements with identical package specifications. The part exhibits superior recovery characteristics (16 ns trr versus 1.8 µs) and lower reverse leakage (2 µA versus 5 µA). The extended operating temperature range (-65 to 175 °C versus -55 to 175 °C) provides additional thermal margin. Selection is appropriate for applications where improved switching performance or lower leakage current provides design benefits. Active product status and RoHS3 compliance are maintained.

VS-2EFH02HM3/I (Similar Manufacturer Part - Higher Current Rating): This part supports 2 A average rectified current, providing a 100% current margin over the 1 A requirement. It carries automotive-grade qualification (AEC-Q101) and exhibits fast recovery characteristics (25 ns trr). Selection is appropriate for applications requiring automotive reliability standards, higher current capacity for thermal margin, or when design specifications benefit from enhanced performance specifications. Active product status, RoHS3 compliance, and automotive qualification are maintained.

Frequently Asked Questions (FAQ)

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

A: Yes. S1DL RVG is a parametric equivalent with identical electrical specifications, voltage ratings, current ratings, and thermal operating range. The only difference is packaging configuration (Tape & Reel versus standard packaging). Both parts are suitable for the same circuit applications.

Q: What are the key differences between the Taiwan Semiconductor Corporation parts and the Vishay parts?

A: The Taiwan Semiconductor Corporation parts (S1DL RFG and S1DL RVG) are standard recovery diodes with 1.8 µs reverse recovery time and 5 µA reverse leakage. The Vishay parts (VS-1EFH02-M3/I and VS-2EFH02HM3/I) are fast recovery diodes with significantly lower reverse recovery times (16 ns and 25 ns respectively) and lower reverse leakage (2 µA). Forward voltage drop is also lower in the Vishay parts. These differences result in improved switching performance and reduced power dissipation in high-frequency applications.

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

A: Yes. VS-2EFH02HM3/I is rated for 2 A average rectified current, which exceeds the 1 A requirement of the S1DL RFG. The higher current rating provides thermal margin and design flexibility. The part is suitable for any application requiring 1 A or less at 200 V reverse voltage.

Q: What is the significance of the automotive qualification on VS-2EFH02HM3/I?

A: The AEC-Q101 qualification indicates that VS-2EFH02HM3/I meets automotive industry reliability and quality standards. This qualification is relevant for applications in automotive systems or other applications requiring automotive-grade component reliability. The S1DL RFG and other substitute parts do not carry this qualification.

Q: Are all substitute parts available in the same DO-219AB package?

A: Yes. All substitute parts listed (S1DL RVG, VS-1EFH02-M3/I, and VS-2EFH02HM3/I) use the DO-219AB package (Sub SMA). This ensures mechanical and electrical compatibility with the original S1DL RFG in surface mount applications.

Q: Do all parts comply with RoHS3 and REACH regulations?

A: Yes. All parts listed (S1DL RFG, S1DL RVG, VS-1EFH02-M3/I, and VS-2EFH02HM3/I) are RoHS3 compliant and REACH unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the difference between standard recovery and fast recovery diodes?

A: Standard recovery diodes (S1DL RFG and S1DL RVG) have longer reverse recovery times (1.8 µs), making them suitable for low-frequency and DC applications. Fast recovery diodes (VS-1EFH02-M3/I and VS-2EFH02HM3/I) have significantly shorter reverse recovery times (16 ns and 25 ns), making them suitable for high-frequency switching applications where reduced switching losses are beneficial.

Q: Can I use these parts interchangeably in my circuit?

A: Electrical interchangeability is confirmed for all parts at the 200 V, 1 A rating level. However, the different recovery characteristics and leakage specifications may affect circuit performance in high-frequency or precision applications. Circuit validation is necessary to confirm performance equivalence in specific applications.
