Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSFBL RTG is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Package / Case: DO-219AB (mechanical compatibility)
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS3 Compliance and MSL 1 rating

Current Rating Considerations: Substitute parts are grouped into two categories based on average rectified current capacity:

1. Direct Current Rating Match (500mA): ES07B-GS08 provides equivalent 500mA current rating with identical voltage and package specifications.

2. Higher Current Rating (≥500mA): ES07B-GS18 (1.2A) and VS-2EFH01HM3/I (2A) provide superior current handling while maintaining 100V voltage rating and DO-219AB package compatibility. These parts are suitable for applications where the RSFBL RTG current rating is insufficient or where design margin is required.

All substitute parts maintain the required fast recovery speed classification, surface mount configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

ES07B-GS08 Selection: ES07B-GS08 is the direct functional equivalent to RSFBL RTG, providing identical voltage rating (100V), current rating (500mA), and package configuration (DO-219AB). This part is suitable for one-to-one replacement in existing designs. ES07B-GS08 carries AEC-Q101 automotive qualification and demonstrates superior reverse recovery time (25 ns versus 150 ns), resulting in lower switching losses. High inventory availability (110,300 pcs) supports production continuity.

ES07B-GS18 Selection: ES07B-GS18 is applicable where design requirements permit higher current capacity (1.2A versus 500mA) while maintaining 100V voltage rating and DO-219AB package compatibility. This part provides design margin for current-limited applications and carries AEC-Q101 automotive qualification. Reverse recovery time of 25 ns offers improved switching performance. Selection of this part requires confirmation that the 1.2A rating does not introduce thermal or circuit design complications.

VS-2EFH01HM3/I Selection: VS-2EFH01HM3/I is applicable for applications requiring maximum current capacity (2A) within the 100V voltage class and DO-219AB package envelope. This part is classified as FRED Pt® technology with the lowest reverse recovery time (16 ns) and reverse leakage current (2 µA), supporting high-frequency switching applications. Extended operating temperature range (-65 to 175°C) accommodates demanding thermal environments. AEC-Q101 automotive qualification is included. Selection of this part requires confirmation that circuit design accommodates the 2A current rating.

All substitute parts maintain Active product status, full RoHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and supply chain compatibility with the RSFBL RTG.

Frequently Asked Questions (FAQ)

Q: Can ES07B-GS08 be used as a direct replacement for RSFBL RTG?

A: Yes. ES07B-GS08 provides identical electrical ratings (100V, 500mA) and package configuration (DO-219AB). Both parts are Surface Mount, fast recovery diodes with RoHS3 compliance and MSL 1 rating. The primary difference is reverse recovery time (25 ns versus 150 ns), which represents improved switching performance in the substitute part.

Q: What is the difference between ES07B-GS18 and ES07B-GS08?

A: The primary difference is average rectified current capacity: ES07B-GS18 is rated for 1.2A while ES07B-GS08 is rated for 500mA. Both parts share identical 100V voltage rating, DO-219AB package, and 25 ns reverse recovery time. ES07B-GS18 is suitable for applications requiring higher current handling within the same voltage and package constraints.

Q: Is VS-2EFH01HM3/I compatible with the RSFBL RTG footprint?

A: Yes. VS-2EFH01HM3/I uses the DO-219AB package, which is mechanically identical to the RSFBL RTG Sub SMA package. Surface mount assembly compatibility is maintained. The part is suitable for PCB designs originally specified for RSFBL RTG without layout modification.

Q: What are the key electrical differences between substitute parts?

A: Reverse recovery time varies across substitutes: RSFBL RTG (150 ns), ES07B-GS08 and ES07B-GS18 (25 ns), and VS-2EFH01HM3/I (16 ns). Reverse leakage current also differs: RSFBL RTG (5 µA), ES07B-GS08 and ES07B-GS18 (10 µA), and VS-2EFH01HM3/I (2 µA). All parts maintain 100V voltage rating and fast recovery speed classification. Current ratings range from 500mA to 2A.

Q: Are all substitute parts automotive qualified?

A: ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I all carry AEC-Q101 automotive qualification. RSFBL RTG does not list automotive qualification in the provided specifications. Applications requiring automotive-grade components should select from the Vishay substitute parts.

Q: What is the operating temperature range for each part?

A: RSFBL RTG, ES07B-GS08, and ES07B-GS18 operate from -55°C to 150°C junction temperature. VS-2EFH01HM3/I extends this range to -65°C to 175°C, providing superior performance in extreme thermal environments.

Q: Do all parts meet RoHS3 compliance?

A: Yes. RSFBL RTG, ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I are all RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Which substitute part offers the best switching performance?

A: VS-2EFH01HM3/I provides the fastest reverse recovery time (16 ns) and lowest reverse leakage current (2 µA), resulting in superior switching performance and reduced power dissipation in high-frequency applications. ES07B-GS08 and ES07B-GS18 offer intermediate performance (25 ns reverse recovery time) compared to RSFBL RTG (150 ns).

Q: Can I use a higher current-rated part in place of RSFBL RTG?

A: Yes, provided circuit design accommodates the higher current rating. ES07B-GS18 (1.2A) and VS-2EFH01HM3/I (2A) are electrically compatible with RSFBL RTG applications and maintain identical voltage rating (100V) and package configuration (DO-219AB). Higher current ratings do not introduce incompatibility; they provide design margin and improved performance characteristics.
