ES2GFS Equivalent & Substitute Parts

Part Overview

The ES2GFS 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 SOD-128 package. This component is classified as a fast recovery diode with a reverse recovery time of 35 ns, suitable for applications requiring efficient switching characteristics at moderate voltage and current levels. The part is Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES2GFS with equivalent parts is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 2 A
• Package / Case: SOD-128
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variation permitted within fast recovery classification (≤ 500 ns)
• Current - Reverse Leakage @ Vr: Variation permitted within specified leakage range
• Capacitance @ Vr, F: Variation permitted based on frequency and voltage conditions

The HS2GFS meets all mandatory matching parameters and is classified as a parametric equivalent. Variations in reverse recovery time (50 ns vs. 35 ns) and capacitance (25 pF vs. 16 pF) remain within acceptable engineering tolerances for general-purpose rectification applications.

Parameter Comparison

Engineering Selection Recommendations

Both ES2GFS and HS2GFS are Active products with identical compliance certifications (RoHS3 Compliant, REACH Unaffected, MSL 1). Selection between these parts is based on the following engineering criteria:

ES2GFS Selection Criteria:

• Applications requiring minimum reverse recovery time (35 ns) for optimized switching efficiency
• Designs sensitive to junction capacitance (16 pF specification)
• Primary part availability and established supply chain

HS2GFS Selection Criteria:

• Equivalent performance in applications where reverse recovery time up to 50 ns is acceptable
• Designs tolerant of higher junction capacitance (25 pF specification)
• Alternative sourcing when ES2GFS inventory is constrained
• Identical voltage, current, and thermal ratings ensure direct functional substitution

Both parts maintain identical forward voltage characteristics (1.3 V @ 2 A), reverse leakage current (1 µA @ 400 V), and operating temperature range (-55°C to 150°C). The SOD-128 package and surface mount configuration are identical, ensuring mechanical and thermal compatibility in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can HS2GFS be used as a direct replacement for ES2GFS in existing designs?

A: Yes. The HS2GFS meets all mandatory electrical parameters: 400 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, and identical SOD-128 surface mount packaging. The reverse recovery time difference (50 ns vs. 35 ns) and capacitance difference (25 pF vs. 16 pF) remain within fast recovery diode classification and do not affect general-purpose rectification performance.

Q: What is the significance of the reverse recovery time difference between ES2GFS (35 ns) and HS2GFS (50 ns)?

A: Reverse recovery time determines the speed at which the diode transitions from forward conduction to reverse blocking. The ES2GFS exhibits faster recovery (35 ns), which reduces switching losses in high-frequency applications. The HS2GFS (50 ns) remains within the fast recovery classification (≤ 500 ns) and is suitable for standard rectification applications where switching frequency does not exceed typical AC line frequency or moderate switching rates.

Q: Are there package or mounting differences between ES2GFS and HS2GFS?

A: No. Both parts use identical SOD-128 surface mount packaging. PCB footprints, reflow soldering profiles, and thermal management considerations are identical. No design modifications are required for mechanical or thermal compatibility.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both ES2GFS and HS2GFS are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical between the two parts.

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

A: The ES2GFS specifies 16 pF at 4 V, 1 MHz, while the HS2GFS specifies 25 pF at the same conditions. Junction capacitance affects high-frequency switching behavior and reverse recovery characteristics. For general-purpose rectification at standard frequencies, this difference is not critical. Applications involving high-frequency switching or sensitive analog circuits should verify capacitance specifications against design requirements.

Q: Are both parts currently in active production?

A: Yes. Both ES2GFS and HS2GFS are classified as Active products with current inventory availability. ES2GFS has 6163 pcs in stock, and HS2GFS has 7176 pcs in stock.
