HS1BL RVG Equivalent & Substitute Parts

Part Overview

The HS1BL RVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when design requirements permit alternative components that maintain electrical and mechanical compatibility within specified parameter tolerances. Equivalent diodes sharing the same voltage rating, current capability, and package footprint are documented to support component procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the HS1BL RVG are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain identical voltage rating (100 V), current rating (1 A), forward voltage drop (950 mV @ 1 A), package type (DO-219AB Sub SMA), and operating temperature range (-55°C to 150°C). These parts are direct functional replacements with no circuit redesign required. Parametric equivalents include ES1BL and ES1BLH.

Similar Parts share the same voltage rating (100 V) and package footprint (DO-219AB) but differ in one or more electrical parameters including current rating, reverse recovery time, or reverse leakage current. Similar parts include ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I. These components require circuit-level evaluation to confirm compatibility with application requirements.

Substitution eligibility is determined by:

Voltage - DC Reverse (Vr) rating equal to or greater than 100 V
Current - Average Rectified (Io) rating equal to or greater than 1 A
Package / Case compatibility: DO-219AB Sub SMA
Operating temperature range encompassing -55°C to 150°C minimum
RoHS3 compliance status

Engineering Selection Recommendations

For Active Product Status Designs:

ES07B-GS18 (Vishay General Semiconductor) is an active product suitable for new designs. This part maintains 100 V reverse voltage rating and exceeds the 1 A current requirement at 1.2 A, providing design margin. The part is available in high inventory (50,100 pcs) and carries RoHS3 compliance. Forward voltage drop is 980 mV @ 1 A, representing a 30 mV increase over the HS1BL RVG specification. Reverse recovery time is 25 ns, faster than the HS1BL RVG at 50 ns.

VS-2EFH01HM3/I (Vishay General Semiconductor, FRED Pt® series) is an active product with AEC-Q101 automotive qualification. This part provides 2 A current rating with superior reverse recovery time of 16 ns and lower reverse leakage current of 2 µA @ 100 V. Operating temperature range extends to 175°C maximum. This part is suitable for applications requiring enhanced performance margins and automotive-grade reliability.

For Existing Design Maintenance:

ES1BL and ES1BLH are parametric equivalents from Taiwan Semiconductor Corporation with identical electrical specifications to the HS1BL RVG. Both parts are classified as "Not For New Designs" but remain available for sustaining production and field replacement applications. ES1BLH includes AEC-Q101 automotive qualification and is available in higher inventory (37,063 pcs) compared to ES1BL (18,860 pcs).

For Current-Limited Applications:

ES07B-GS08 (Vishay General Semiconductor) is rated for 500 mA average rectified current, below the 1 A requirement of the HS1BL RVG. This part is not suitable as a direct substitute for applications requiring full 1 A current capacity. Selection of this part requires circuit-level verification that application current demands do not exceed 500 mA.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for HS1BL RVG in new designs?

A: ES1BL is a parametric equivalent with identical voltage, current, and forward voltage specifications. However, ES1BL is classified as "Not For New Designs" by the manufacturer. For new designs, ES07B-GS18 or VS-2EFH01HM3/I are recommended as active product alternatives.

Q: What is the difference between ES1BL and ES1BLH?

A: Both parts share identical electrical parameters (100 V, 1 A, 950 mV forward voltage). ES1BLH includes AEC-Q101 automotive qualification and is available in higher inventory. ES1BLH is suitable for automotive applications requiring formal qualification documentation.

Q: Can VS-2EFH01HM3/I replace HS1BL RVG in all applications?

A: VS-2EFH01HM3/I maintains the 100 V voltage rating and exceeds the 1 A current requirement at 2 A. The part is electrically compatible and provides superior performance characteristics (16 ns reverse recovery time versus 50 ns). Operating temperature range extends to 175°C. Substitution is valid for all applications where the HS1BL RVG is specified, with the understanding that performance margins are enhanced.

Q: Why is ES07B-GS08 listed as a similar part rather than a substitute?

A: ES07B-GS08 is rated for 500 mA average rectified current, which is below the 1 A requirement of the HS1BL RVG. While the voltage rating and package are compatible, the reduced current capacity requires circuit-level verification. This part is suitable only for applications where current demand does not exceed 500 mA.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES1BL, ES1BLH, ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the HS1BL RVG specification.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) indicates the speed at which the diode transitions from forward conduction to reverse blocking. The HS1BL RVG specifies 50 ns trr. Substitute parts with lower trr values (ES1BL and ES1BLH at 35 ns, ES07B-GS18 at 25 ns, VS-2EFH01HM3/I at 16 ns) provide faster switching characteristics. Faster recovery reduces switching losses in high-frequency applications but does not affect DC circuit operation.

Q: Can HS1BL RVG be substituted with ES07B-GS18 in automotive applications?

A: ES07B-GS18 is an active product with 100 V rating and 1.2 A current capacity. However, ES07B-GS18 does not carry AEC-Q101 automotive qualification. For automotive applications requiring formal qualification, ES1BLH or VS-2EFH01HM3/I are recommended as both parts include AEC-Q101 certification.

Q: What inventory considerations apply to substitute part selection?

A: ES07B-GS08 has the highest inventory at 110,300 pcs. ES07B-GS18 has 50,100 pcs. ES1BLH has 37,063 pcs. ES1BL has 18,860 pcs. VS-2EFH01HM3/I has 10,912 pcs. Inventory levels support component availability for both new production and sustaining supply requirements.
