HS1GL Equivalent & Substitute Parts

Part Overview

The HS1GL is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400V DC reverse voltage and 1A average rectified current. This component is classified as a high-efficiency rectifier with a 50ns reverse recovery time, packaged in SOD-123 surface mount configuration. The HS1GL carries a product status of "Not For New Designs," indicating it is an obsolete or legacy component. Identifying equivalent substitute parts is necessary to support existing designs, facilitate production continuity, and ensure long-term component availability for maintenance and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS1GL is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 400V minimum
• Current - Average Rectified (Io): 1A minimum
• Reverse Recovery Time (trr): 50ns maximum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package compatibility: SOD-123 or SOD-123W (pin-compatible variants)

Compliance Criteria:

• RoHS3 Compliant
• REACH Unaffected

The HS1GLW qualifies as a direct substitute because it maintains all critical electrical parameters (400V, 1A, 50ns recovery time, fast recovery classification) and operates within compatible surface mount package variants. The SOD-123W package is a physically compatible variant of SOD-123 with identical pin configuration and footprint compatibility.

Engineering Selection Recommendations

The HS1GLW is the designated manufacturer-recommended substitute for the HS1GL. Selection of the HS1GLW is supported by the following engineering factors:

Product Status: The HS1GLW carries an "Active" product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards. The HS1GL is classified as "Not For New Designs," making the HS1GLW the appropriate choice for production continuity and long-term supply chain stability.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

Electrical Performance: The HS1GLW maintains all critical electrical specifications required for 400V, 1A fast recovery rectifier applications. The forward voltage is slightly elevated (1.7V versus 1.3V), which represents a minor increase in conduction loss but remains within acceptable operating parameters for standard rectifier applications. Reverse leakage current is improved (1µA versus 5µA), and junction temperature range is extended (-55 to 175°C versus -55 to 150°C), providing enhanced thermal margin.

Package Compatibility: The SOD-123W package is a pin-compatible variant of SOD-123, permitting direct substitution on existing printed circuit board layouts without modification to footprints or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the HS1GLW be used as a direct replacement for the HS1GL in existing designs?

A: Yes. The HS1GLW is the manufacturer-recommended substitute and maintains electrical equivalence across all critical parameters: 400V reverse voltage, 1A average rectified current, and 50ns reverse recovery time. The SOD-123W package is pin-compatible with SOD-123, permitting direct substitution without circuit board redesign.

Q: What is the difference between SOD-123 and SOD-123W packages?

A: SOD-123W is a wider variant of the SOD-123 package with identical pin configuration and electrical performance. Both are surface mount packages suitable for automated assembly. The SOD-123W footprint is physically compatible with SOD-123 layouts, allowing direct substitution.

Q: Why is the forward voltage higher on the HS1GLW (1.7V) compared to the HS1GL (1.3V)?

A: Forward voltage variation is a normal characteristic of semiconductor manufacturing and does not indicate incompatibility. The HS1GLW forward voltage of 1.7V remains within acceptable operating parameters for 400V, 1A rectifier applications. This difference results in slightly increased conduction loss but does not affect circuit functionality in standard rectifier configurations.

Q: Is the HS1GLW suitable for new product designs?

A: Yes. The HS1GLW carries an "Active" product status, indicating it is approved for new designs and supported by the manufacturer for ongoing production and supply.

Q: What is the significance of the lower reverse leakage current in the HS1GLW?

A: The HS1GLW exhibits lower reverse leakage current (1µA versus 5µA at 400V), which represents improved leakage performance. This characteristic is beneficial in applications sensitive to reverse current, such as precision rectification or low-power circuits, but does not affect compatibility in standard applications.

Q: Are there any temperature range considerations when substituting the HS1GLW for the HS1GL?

A: The HS1GLW operates across a wider junction temperature range (-55 to 175°C versus -55 to 150°C). This extended range provides additional thermal margin and is fully compatible with applications designed for the HS1GL temperature specification.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both the HS1GL and HS1GLW are ROHS3 compliant and REACH Unaffected, satisfying environmental and hazardous substance regulations applicable to electronic components.
