HS1BL R3G Equivalent & Substitute Parts

Part Overview

The HS1BL R3G 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 ROHS3 certification.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative electrical characteristics such as improved reverse recovery time, reduced leakage current, or higher current ratings. The parts listed below provide parametric equivalence or functional similarity within the 100 V rectifier diode category.

Substitute Part Grouping Explanation

Substitution eligibility for the HS1BL R3G is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal 100 V
Package / Case: Must be DO-219AB (Sub SMA)
Mounting Type: Must be Surface Mount
RoHS Status: Must be ROHS3 Compliant

Secondary Compatibility Parameters:

Current - Average Rectified (Io): Equal or greater than 1 A
Voltage - Forward (Vf) (Max) @ If: Must not exceed 950 mV @ 1 A
Operating Temperature - Junction: Must encompass -55°C to 150°C minimum range

Parametric Equivalent Parts (ES1BL, ES1BLH) meet all primary and secondary criteria with identical or superior electrical performance.

Similar Parts (ES07B-GS08, ES07B-GS18, VS-2EFH01HM3/I) share the same package and voltage rating but may have variations in current rating, reverse recovery time, or leakage characteristics. These parts are suitable for applications where the HS1BL R3G specifications can accommodate the alternative electrical parameters.

Engineering Selection Recommendations

For Direct Parametric Equivalence:

ES1BL and ES1BLH are parametric equivalents to the HS1BL R3G, maintaining identical voltage and current ratings with the same DO-219AB package. Both parts are RoHS3 compliant. ES1BLH carries AEC-Q101 automotive qualification and is recommended for automotive applications requiring this certification. Both ES1BL and ES1BLH are classified as "Not For New Designs," indicating these parts are in mature or declining production phases. The HS1BL R3G remains the preferred choice for new designs due to its Active product status.

For Active Product Alternatives:

ES07B-GS18 (Vishay) provides a direct Active product substitute with identical 100 V rating and 1.2 A current capability, exceeding the HS1BL R3G's 1 A specification. This part features improved reverse recovery time (25 ns versus 50 ns) and is suitable for applications benefiting from faster switching characteristics. ES07B-GS18 is RoHS3 compliant and available in Tape & Reel packaging.

ES07B-GS08 (Vishay) is an Active product rated for 500 mA, which is below the HS1BL R3G's 1 A specification. This part is suitable only for applications with reduced current requirements and carries AEC-Q101 automotive qualification.

VS-2EFH01HM3/I (Vishay FRED Pt® series) is an Active product rated for 2 A with superior reverse recovery time (16 ns) and lower reverse leakage current (2 µA). This part extends the operating temperature range to -65°C to 175°C and carries AEC-Q101 qualification. Selection of this part is appropriate for high-speed switching applications or designs requiring enhanced thermal performance.

Compliance Considerations:

All listed parts maintain ROHS3 compliance and are REACH unaffected. Parts requiring automotive qualification (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) carry AEC-Q101 certification. Selection should align with application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can ES1BL or ES1BLH be used as direct replacements for HS1BL R3G?

A: ES1BL and ES1BLH are parametric equivalents with identical voltage (100 V) and current (1 A) ratings, matching forward voltage and operating temperature specifications. Both use the DO-219AB package. However, both parts carry "Not For New Designs" status, whereas HS1BL R3G is Active. For new designs, HS1BL R3G is the preferred selection. For legacy system maintenance or inventory management, ES1BL and ES1BLH provide functional equivalence.

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

A: Both parts are manufactured by Vishay and use the DO-219AB package with 100 V rating. ES07B-GS08 is rated for 500 mA average rectified current, while ES07B-GS18 is rated for 1.2 A. ES07B-GS18 matches or exceeds the HS1BL R3G's 1 A specification and is suitable for direct substitution in applications requiring the full 1 A current capacity. ES07B-GS08 is appropriate only for applications with reduced current requirements below 500 mA.

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

A: VS-2EFH01HM3/I extends the junction operating temperature range to -65°C to 175°C, compared to the HS1BL R3G's -55°C to 150°C. This extended range provides additional thermal margin for high-temperature applications. The part is suitable for use in environments exceeding the HS1BL R3G's temperature limits. Applications operating within the HS1BL R3G's temperature range will function identically with either part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES1BL, ES1BLH, ES07B-GS08, ES07B-GS18, VS-2EFH01HM3/I) are RoHS3 compliant and REACH unaffected, matching the HS1BL R3G's environmental compliance status.

Q: Which substitute part has the fastest reverse recovery time?

A: VS-2EFH01HM3/I has the fastest reverse recovery time at 16 ns, compared to the HS1BL R3G's 50 ns. ES07B-GS08 and ES07B-GS18 both feature 25 ns reverse recovery time. Faster reverse recovery time reduces switching losses and is beneficial in high-frequency switching applications.

Q: Can I use a substitute part with higher current rating in place of HS1BL R3G?

A: Yes. Parts with equal or higher current ratings (ES07B-GS18 at 1.2 A, VS-2EFH01HM3/I at 2 A) are suitable for applications designed for the HS1BL R3G's 1 A specification. The higher current rating provides additional design margin and does not create compatibility issues. However, ES07B-GS08 with 500 mA rating is unsuitable for applications requiring the full 1 A capacity.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this certification (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) meet automotive reliability and quality requirements. Selection of AEC-Q101 qualified parts is mandatory for automotive applications. The HS1BL R3G does not carry this certification and is not suitable for automotive applications requiring AEC-Q101 compliance.

Q: Why is HS1BL R3G preferred over ES1BL and ES1BLH for new designs?

A: HS1BL R3G carries Active product status, indicating ongoing production support and availability. ES1BL and ES1BLH are classified as "Not For New Designs," signifying mature or declining production phases with potential future discontinuation. Active products provide longer supply chain stability and are the standard choice for new design implementations.
