ES2GAL General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The ES2GAL is an active general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the DO-221AC (SMA Flat Leads) package. This component operates at 400 V DC reverse voltage with a 2 A average rectified current rating and features fast recovery characteristics with a 35 ns reverse recovery time. The diode is specified for junction temperatures ranging from -55°C to 150°C and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, package type, and thermal operating range. Identifying suitable alternatives ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES2GAL is determined by strict equivalence across the following critical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage (Vr) rating of 400 V or greater to ensure safe operation in the same circuit topology.

Current Rating: The average rectified current (Io) must be rated at 2 A or greater to support the same load conditions without thermal stress.

Forward Voltage: The forward voltage drop (Vf) at rated current must not exceed 1.3 V @ 2 A to maintain circuit efficiency and thermal performance.

Package Compatibility: The substitute must use the DO-221AC (SMA Flat Leads) package to ensure mechanical fit and PCB assembly compatibility.

Thermal Range: The operating junction temperature range must span -55°C to 150°C or greater to support the same environmental conditions.

Compliance: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels (MSL 1) for manufacturing and storage compatibility.

The HS2GAL meets all these criteria and is classified as a parametric equivalent substitute for the ES2GAL.

Parameter Comparison

Engineering Selection Recommendations

Both the ES2GAL and HS2GAL are active products manufactured by Taiwan Semiconductor Corporation with identical ROHS3 compliance and REACH unaffected status. Both components meet the electrical and mechanical requirements for general purpose rectification at 400 V and 2 A ratings.

The ES2GAL features a 35 ns reverse recovery time, while the HS2GAL has a 50 ns reverse recovery time. This difference reflects standard manufacturing variation within the fast recovery diode classification (≤500 ns, >200 mA). The ES2GAL exhibits lower junction capacitance (16 pF) compared to the HS2GAL (25 pF), which may provide marginal advantages in high-frequency switching applications.

Selection between these parts should be based on circuit performance requirements and supply availability. Both parts are suitable for direct substitution in applications where the specified electrical parameters are met.

Frequently Asked Questions (FAQ)

Q: Can the HS2GAL replace the ES2GAL in an existing design?

A: Yes. The HS2GAL is a parametric equivalent substitute. Both parts share identical voltage ratings (400 V), current ratings (2 A), forward voltage characteristics (1.3 V @ 2 A), package type (DO-221AC SMA), and operating temperature range (-55°C to 150°C). The HS2GAL reverse recovery time of 50 ns remains within the fast recovery classification and is acceptable for general purpose rectification applications.

Q: What is the difference in reverse recovery time between these parts?

A: The ES2GAL has a reverse recovery time (trr) of 35 ns, while the HS2GAL has a trr of 50 ns. Both values fall within the fast recovery diode specification (≤500 ns, >200 mA). The 15 ns difference is within normal manufacturing tolerances for this diode category and does not affect compatibility in standard rectification circuits.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the ES2GAL and HS2GAL use the identical DO-221AC package with SMA flat leads. PCB footprints, solder pad layouts, and assembly processes are fully compatible. No design modifications are required for mechanical or electrical integration.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). Both are rated for junction temperatures from -55°C to 150°C. Manufacturing, storage, and handling requirements are identical.

Q: What is the significance of the capacitance difference between these parts?

A: The ES2GAL has a junction capacitance of 16 pF @ 4 V, 1 MHz, while the HS2GAL has 25 pF @ 4 V, 1 MHz. This difference may have minor effects in high-frequency switching or RF applications where parasitic capacitance influences circuit behavior. For standard power supply and rectification applications, this difference is not significant.

Q: Which part should be selected for new designs?

A: Selection should be based on supply availability and specific circuit performance requirements. Both parts are active products with equivalent electrical performance for general purpose rectification.
