HS1BL RUG Equivalent & Substitute Parts

Part Overview

The HS1BL RUG 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 (DO-219AB). This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching or exceeding the electrical performance parameters of the HS1BL RUG while maintaining compatibility with the DO-219AB package form factor. Substitutes are necessary when the primary part becomes unavailable, when alternative sourcing is required, or when design requirements permit higher performance specifications.

Substitute Part Grouping Explanation

Substitution logic for the HS1BL RUG is based on the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) rating of 100 V or higher
Current - Average Rectified (Io) rating of 1 A or higher
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA
Operating Temperature Range: -55°C to 150°C minimum

Parametric Equivalent Parts (ES1BL, ES1BLH) maintain identical voltage and current ratings with the same package and mounting type. These parts are direct functional replacements with equivalent or superior reverse recovery time performance.

Similar Parts (ES07B-GS08, ES07B-GS18, VS-2EFH01HM3/I) share the same 100 V reverse voltage rating and DO-219AB package but differ in current rating or reverse recovery characteristics. These parts are suitable for applications where the higher current capacity or improved recovery time does not create design conflicts.

Engineering Selection Recommendations

For Direct Parametric Equivalence:

ES1BL and ES1BLH are parametric equivalents to the HS1BL RUG, maintaining the same 100 V / 1 A electrical specifications and DO-219AB package. Both parts are ROHS3 compliant. ES1BLH carries AEC-Q101 automotive qualification and is recommended for automotive applications. Both ES1BL and ES1BLH are classified as "Not For New Designs," indicating these are legacy or mature products suitable for replacement or continuation applications but not recommended for new design initiation.

For Active Product Status with Enhanced Performance:

ES07B-GS18 (Vishay) is an active product offering 1.2 A current capacity at the same 100 V voltage rating. This part provides improved current headroom while maintaining the DO-219AB package and fast recovery characteristics. ES07B-GS18 is suitable for designs requiring higher current margin or where Vishay sourcing is preferred.

VS-2EFH01HM3/I (Vishay FRED Pt® series) is an active product rated for 2 A at 100 V with superior reverse recovery time (16 ns versus 50 ns for HS1BL RUG) and lower reverse leakage current (2 µA versus 5 µA). This part includes AEC-Q101 automotive qualification and extended operating temperature range (-65 to 175°C). VS-2EFH01HM3/I is suitable for applications requiring enhanced performance specifications or automotive-grade reliability.

For Current-Limited Applications:

ES07B-GS08 (Vishay) is rated for 500 mA at 100 V and is suitable only for applications where the design current requirement does not exceed 500 mA. This part is not recommended as a substitute for the HS1BL RUG in 1 A applications.

Frequently Asked Questions (FAQ)

Q: Can ES1BL or ES1BLH be used as direct replacements for HS1BL RUG?

A: Yes. ES1BL and ES1BLH are parametric equivalents with identical 100 V / 1 A ratings, forward voltage characteristics, and DO-219AB package. Both maintain ROHS3 compliance. However, both are classified as "Not For New Designs." ES1BLH includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring legacy part continuation.

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

A: ES07B-GS08 is rated for 500 mA average rectified current, while ES07B-GS18 is rated for 1.2 A. Both share the same 100 V reverse voltage rating, DO-219AB package, and fast recovery characteristics. ES07B-GS18 is the appropriate substitute for HS1BL RUG in 1 A applications. ES07B-GS08 is suitable only for applications with current requirements not exceeding 500 mA.

Q: Why does VS-2EFH01HM3/I have a different operating temperature range?

A: VS-2EFH01HM3/I is rated for -65 to 175°C junction temperature, compared to -55 to 150°C for HS1BL RUG. This extended range reflects the FRED Pt® technology platform used by Vishay and provides additional thermal margin for high-temperature applications. The part is suitable for use in any application within the HS1BL RUG temperature range and beyond.

Q: Are all substitute parts available in the same packaging format?

A: All listed substitute parts use the DO-219AB (Sub SMA) package, ensuring mechanical and thermal compatibility with HS1BL RUG. Packaging formats differ in tape & reel (TR) or cut tape (CT) configurations, which affect handling and assembly but not electrical performance or board-level compatibility.

Q: Which substitute part offers the best reverse recovery performance?

A: VS-2EFH01HM3/I offers the fastest reverse recovery time at 16 ns, compared to 50 ns for HS1BL RUG. ES07B-GS08 and ES07B-GS18 also provide improved recovery time at 25 ns. Faster recovery time reduces switching losses and electromagnetic interference in high-frequency applications.

Q: Is AEC-Q101 qualification required for my application?

A: AEC-Q101 qualification is required for automotive applications. ES1BLH, ES07B-GS08, and VS-2EFH01HM3/I carry this qualification. HS1BL RUG, ES1BL, and ES07B-GS18 do not list AEC-Q101 qualification. Verify application requirements before selecting a substitute part.

Q: Can I use a higher-current-rated part as a substitute?

A: Yes. Parts rated for higher current (ES07B-GS18 at 1.2 A or VS-2EFH01HM3/I at 2 A) are suitable substitutes for the 1 A HS1BL RUG, provided all other electrical and mechanical parameters are compatible. Higher current rating provides design margin and does not create functional conflicts in applications designed for 1 A operation.
