HS2GAL Equivalent & Substitute Parts

Part Overview

The HS2GAL is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 2 A average rectified current in a surface mount Thin SMA package. This component is classified as a fast recovery diode with a reverse recovery time of 50 ns, suitable for standard rectification applications requiring moderate voltage and current ratings.

The HS2GAL maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are identified based on matching electrical specifications and mechanical compatibility within the DO-221AC SMA package family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS2GAL are identified through parametric equivalence within the general-purpose rectifier diode category. The substitution logic is based on the following critical parameters that must remain constant or within acceptable tolerance:

• Voltage Rating: DC reverse voltage of 400 V (maximum)
• Current Rating: Average rectified current of 2 A
• Forward Voltage Drop: 1.3 V maximum at 2 A forward current
• Package Type: DO-221AC SMA Flat Leads (Thin SMA)
• Mounting Configuration: Surface mount technology
• Temperature Range: Operating junction temperature from -55°C to 150°C
• Compliance Standards: RoHS3 compliance and MSL 1 rating

The ES2GAL meets all these criteria and is therefore classified as a parametric equivalent. Both parts share identical voltage, current, and temperature specifications, with differences limited to reverse recovery time (35 ns versus 50 ns) and junction capacitance (16 pF versus 25 pF), which represent performance enhancements rather than deviations from the core electrical contract.

Parameter Comparison

Engineering Selection Recommendations

Both the HS2GAL and ES2GAL are Active products manufactured by Taiwan Semiconductor Corporation and maintain full RoHS3 compliance with REACH Unaffected status. Selection between these parts is based on application-specific performance requirements and inventory availability.

The HS2GAL features a reverse recovery time of 50 ns and junction capacitance of 25 pF at 4 V, 1 MHz. The ES2GAL provides improved reverse recovery time of 35 ns and reduced junction capacitance of 16 pF at the same measurement conditions. Both parts satisfy the core electrical specifications of 400 V reverse voltage, 2 A average rectified current, and 1.3 V forward voltage drop at 2 A.

Selection should prioritize the part with the shortest lead time and lowest cost when application performance margins accommodate either specification. For applications sensitive to switching speed or high-frequency operation, the ES2GAL offers performance advantages. Both parts are suitable for direct substitution in standard rectification circuits within the specified voltage and current ranges.

Frequently Asked Questions (FAQ)

Q: Can the ES2GAL directly replace the HS2GAL in existing designs?

A: Yes. Both parts share identical voltage ratings (400 V), current ratings (2 A), forward voltage characteristics (1.3 V @ 2 A), and package configuration (DO-221AC SMA Flat Leads). The ES2GAL features faster reverse recovery (35 ns versus 50 ns) and lower capacitance (16 pF versus 25 pF), which represent performance improvements compatible with HS2GAL circuit requirements.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: DC reverse voltage rating (400 V), average rectified current (2 A), forward voltage drop (1.3 V @ 2 A), operating temperature range (-55°C to 150°C), and package type (DO-221AC SMA Flat Leads). Both the HS2GAL and ES2GAL meet these criteria.

Q: Are there differences in package or mounting between these parts?

A: No. Both the HS2GAL and ES2GAL use the DO-221AC SMA Flat Leads package with surface mount configuration. Mechanical compatibility and PCB footprint requirements are identical.

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

A: The ES2GAL reverse recovery time of 35 ns is faster than the HS2GAL at 50 ns. This difference affects switching speed in high-frequency applications. Both values fall within the fast recovery classification (≤ 500 ns). The faster recovery of the ES2GAL reduces switching losses in applications operating above 100 kHz.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HS2GAL and ES2GAL are RoHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity level. Both maintain Active product status.

Q: What is the difference in junction capacitance, and does it matter?

A: The HS2GAL has 25 pF junction capacitance at 4 V, 1 MHz, while the ES2GAL has 16 pF at the same conditions. Lower capacitance in the ES2GAL reduces parasitic effects in high-frequency circuits and improves switching performance. For standard rectification applications below 100 kHz, this difference is negligible.

Q: Which part should be selected for new designs?

A: Selection is based on availability, cost, and application frequency requirements. The ES2GAL offers superior reverse recovery time and lower capacitance, making it suitable for higher-frequency applications. The HS2GAL is appropriate for standard rectification circuits where switching speed is not a limiting factor. Both parts are functionally equivalent for 400 V, 2 A rectification.
