HS1BL MHG Equivalent & Substitute Parts

Part Overview

The HS1BL MHG 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). The device 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 MHG while maintaining compatibility with the DO-219AB package form factor. Substitutes are necessary when the primary part becomes unavailable or when design requirements call for alternative manufacturers or enhanced specifications.

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

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

Performance Parameters (Equal or Superior):

Current - Average Rectified (Io): 1 A or greater
Voltage - Forward (Vf) (Max) @ If: 950 mV or lower at rated current
Reverse Recovery Time (trr): 50 ns or faster
Current - Reverse Leakage @ Vr: 5 µA or lower at 100 V

Substitute parts are classified into two categories:

Parametric Equivalents: Parts that match all mandatory parameters and maintain electrical performance within the specified ranges. These include ES1BL and ES1BLH from Taiwan Semiconductor Corporation.

Similar Parts: Parts that match mandatory parameters but may exceed current ratings or offer enhanced performance characteristics. These include ES07B-GS08, ES07B-GS18 from Vishay General Semiconductor - Diodes Division, and VS-2EFH01HM3/I from Vishay General Semiconductor - Diodes Division.

Engineering Selection Recommendations

For Direct Replacement (Active Product Status):

ES07B-GS18 is the recommended substitute when Active product status is required. This part maintains 100 V reverse voltage rating, exceeds the 1 A current requirement at 1.2 A, and is manufactured by Vishay General Semiconductor - Diodes Division with Active product status. The part is RoHS3 compliant and suitable for new designs.

VS-2EFH01HM3/I provides enhanced performance with 2 A current rating, 16 ns reverse recovery time, and AEC-Q101 automotive qualification. This part is suitable for applications requiring higher current capacity or automotive-grade reliability. Operating temperature range extends to 175°C.

For Existing Designs (Legacy Support):

ES1BL and ES1BLH are parametric equivalents with improved reverse recovery time (35 ns versus 50 ns). Both parts are classified as Not For New Designs but remain available for existing production. ES1BLH includes AEC-Q101 automotive qualification.

Current-Limited Applications:

ES07B-GS08 is suitable only for applications requiring 500 mA or less average rectified current. This part offers the fastest reverse recovery time (25 ns) among all substitutes and includes AEC-Q101 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can ES07B-GS08 be used as a direct replacement for HS1BL MHG?

A: ES07B-GS08 is not suitable as a direct replacement. While it matches the 100 V reverse voltage rating and DO-219AB package, the current rating is 500 mA, which is insufficient for applications requiring 1 A average rectified current. Use this part only in circuits designed for 500 mA or lower current.

Q: What is the difference between ES1BL and ES1BLH?

A: Both parts are parametric equivalents with identical electrical specifications. ES1BLH includes AEC-Q101 automotive qualification and is designated as Automotive grade. ES1BL is Standard grade. Both are classified as Not For New Designs.

Q: Is VS-2EFH01HM3/I compatible with the HS1BL MHG footprint?

A: Yes. VS-2EFH01HM3/I uses the DO-219AB (Sub SMA) package, which is mechanically and electrically compatible with the HS1BL MHG footprint. The part can be used as a direct replacement with enhanced performance characteristics including 2 A current rating and 16 ns reverse recovery time.

Q: Why does ES07B-GS18 have a higher current rating than HS1BL MHG?

A: ES07B-GS18 is rated for 1.2 A average rectified current, exceeding the 1 A specification of HS1BL MHG. This higher rating does not prevent use in 1 A applications; the device will operate within its specifications at lower current levels.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the environmental compliance status of the HS1BL MHG.

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

A: Reverse recovery time (trr) affects switching speed and switching losses. HS1BL MHG has 50 ns trr. Substitutes offer faster recovery: ES1BL and ES1BLH at 35 ns, ES07B-GS08 and ES07B-GS18 at 25 ns, and VS-2EFH01HM3/I at 16 ns. Faster recovery reduces power dissipation in high-frequency switching applications.

Q: Can HS1BL MHG be used in automotive applications?

A: HS1BL MHG is Standard grade without AEC-Q101 qualification. For automotive applications requiring AEC-Q101 certification, use ES1BLH or VS-2EFH01HM3/I.

Q: What packaging formats are available for these substitutes?

A: ES1BL and ES1BLH are supplied in Tape & Reel (TR) format. ES07B-GS08 is available in Cut Tape (CT) & Digi-Reel format. ES07B-GS18 and VS-2EFH01HM3/I are supplied in Tape & Reel (TR) format. Verify packaging requirements for your assembly process.
