HS1BL RTG Equivalent & Substitute Parts

Part Overview

The HS1BL RTG 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 features fast recovery characteristics with a reverse recovery time of 50 ns and operates across a junction temperature range of -55°C to 150°C. This part is currently in active product status and is RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances and mechanical compatibility is maintained. Alternative sources and variants may be required due to inventory availability, product lifecycle transitions, or specific application requirements such as automotive qualification.

Substitute Part Grouping Explanation

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

Mandatory Compatibility Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io): 1 A minimum
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Operating Temperature Range: Must encompass or exceed -55°C to 150°C
RoHS Status: ROHS3 Compliant

Electrical Performance Parameters:

Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A or lower
Reverse Recovery Time (trr): 50 ns or lower
Current - Reverse Leakage @ Vr: 5 µA @ 100 V or lower

Substitute parts are classified into two categories:

Parametric Equivalents: Parts that meet or exceed all mandatory compatibility criteria and maintain electrical performance within specified tolerances. These parts are direct functional replacements.

Similar Parts: Parts that meet mandatory compatibility criteria but may have enhanced electrical performance characteristics (lower trr, lower leakage current, higher current rating) or additional qualifications (automotive grade, AEC-Q101). These parts are suitable for applications where enhanced performance is acceptable.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1BL and ES1BLH are parametric equivalents to the HS1BL RTG, maintaining identical voltage and current ratings with improved reverse recovery time (35 ns versus 50 ns). Both parts are manufactured by Taiwan Semiconductor Corporation and are packaged in DO-219AB Sub SMA format. However, both parts carry a "Not For New Designs" product status designation. ES1BL is available in standard packaging (Tape & Reel), while ES1BLH includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring automotive compliance.

For Enhanced Performance (Similar Parts):

ES07B-GS08 (Vishay) is suitable for applications where current requirements do not exceed 500 mA. This part offers superior reverse recovery time (25 ns) and includes automotive qualification (AEC-Q101). The higher forward voltage (980 mV @ 1 A) must be evaluated against application requirements.

ES07B-GS18 (Vishay) provides 1.2 A current rating with 25 ns reverse recovery time and is in active product status. This part is suitable for applications requiring higher current capacity with improved switching performance.

VS-2EFH01HM3/I (Vishay FRED Pt® series) offers the highest performance with 2 A current rating, 16 ns reverse recovery time, and 2 µA reverse leakage current. This part includes automotive qualification (AEC-Q101) and extended operating temperature range (-65°C to 175°C). Selection of this part is appropriate when enhanced performance and automotive compliance are required.

Product Status Consideration:

The HS1BL RTG maintains active product status. Substitute parts ES1BL and ES1BLH are designated "Not For New Designs," indicating potential future discontinuation. For new design implementations, ES07B-GS18 or VS-2EFH01HM3/I are recommended as they maintain active product status and provide enhanced electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for HS1BL RTG?

A: Yes. ES1BL meets all mandatory compatibility criteria: 100 V reverse voltage rating, 1 A current rating, DO-219AB Sub SMA package, and surface mount configuration. Electrical performance is equivalent or superior (35 ns trr versus 50 ns). However, ES1BL carries "Not For New Designs" status, indicating potential future discontinuation.

Q: What is the difference between ES1BL and ES1BLH?

A: Both parts are parametric equivalents with identical electrical specifications. ES1BLH includes automotive-grade qualification (AEC-Q101) and is designated for automotive applications. ES1BL is standard grade. Both carry "Not For New Designs" status.

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

A: ES07B-GS08 has a maximum current rating of 500 mA, which is below the HS1BL RTG specification of 1 A. This part is suitable only for applications where current requirements do not exceed 500 mA. The part offers superior reverse recovery time (25 ns) and automotive qualification (AEC-Q101).

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

A: VS-2EFH01HM3/I meets all mandatory compatibility criteria and exceeds electrical performance specifications. The 2 A current rating, 16 ns reverse recovery time, and extended temperature range (-65°C to 175°C) make this part suitable for applications requiring enhanced performance. The part is in active product status and includes automotive qualification (AEC-Q101).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, matching the compliance status of the HS1BL RTG.

Q: What is the significance of reverse recovery time in selecting a substitute?

A: Reverse recovery time (trr) determines switching speed and affects electromagnetic interference (EMI) characteristics. The HS1BL RTG specifies 50 ns maximum. All listed substitute parts meet or exceed this specification with lower trr values (35 ns, 25 ns, or 16 ns), resulting in faster switching and reduced EMI. Lower trr values are compatible with applications designed for the HS1BL RTG.

Q: Can I use a substitute part with higher current rating than required?

A: Yes. Parts with higher current ratings (ES07B-GS18 at 1.2 A or VS-2EFH01HM3/I at 2 A) are suitable for applications requiring 1 A or less. The higher rating provides design margin and does not negatively impact circuit performance when the actual current demand is lower.

Q: What packaging options are available for substitute parts?

A: All substitute parts use DO-219AB Sub SMA surface mount package, matching the HS1BL RTG. Packaging formats vary: ES1BL and ES1BLH are supplied in Tape & Reel (TR); ES07B-GS08 is available in Cut Tape (CT) & Digi-Reel®; ES07B-GS18 and VS-2EFH01HM3/I are supplied in Tape & Reel (TR).

Q: Are automotive-qualified parts necessary for non-automotive applications?

A: Automotive qualification (AEC-Q101) is not required for non-automotive applications. However, automotive-qualified parts (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) undergo additional testing and screening, which may provide enhanced reliability for demanding applications. Selection should be based on application requirements and cost considerations.
