ES1GL Equivalent & Substitute Parts

Part Overview

The ES1GL is a general-purpose rectifier diode rated for 400 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The fast recovery characteristic (35 ns reverse recovery time) and standard technology make it suitable for applications requiring efficient switching performance in low-to-medium power rectification circuits.

Due to its discontinued design status, equivalent and substitute parts are necessary for ongoing production support, maintenance applications, and design transitions to active product lines.

Substitute Part Grouping Explanation

Substitution of the ES1GL is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

Voltage - DC Reverse (Vr): 400 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) @ If: 1.3 V @ 1 A
Reverse Recovery Time (trr): 35 ns
Current - Reverse Leakage @ Vr: 5 µA @ 400 V
Speed Classification: Fast Recovery ≤ 500ns, > 200mA

Mechanical Parameters (Must Match):

Mounting Type: Surface Mount
Supplier Device Package: Sub SMA or compatible package

Compliance Parameters (Must Match):

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (DO-219AB Sub SMA Package) Parts ES1GL M2G, ES1GL MHG, ES1GL MQG, ES1GL MTG, ES1GL RFG, ES1GL RHG, ES1GL RQG, and ES1GL RTG maintain identical electrical specifications and the same Sub SMA package configuration. These parts differ only in manufacturing date codes or internal lot designations and are direct functional replacements.

Category 2: Package Variant (SOD-123W Package) Part ES1GLW provides electrical equivalence with a different surface mount package (SOD-123W instead of Sub SMA). This substitute is suitable only when the PCB layout and assembly process accommodate the SOD-123W package footprint. ES1GLW also supports an extended operating temperature range (-55°C to 175°C versus -55°C to 150°C).

Engineering Selection Recommendations

For Direct Package Replacement (Sub SMA DO-219AB):

Parts ES1GL M2G, ES1GL MHG, ES1GL MQG, ES1GL MTG, ES1GL RFG, ES1GL RHG, ES1GL RQG, ES1GL RTG, and ES1GL RUG are functionally and mechanically identical to the ES1GL. All are manufactured by Taiwan Semiconductor Corporation and carry Active product status, making them suitable for production use. These parts maintain the same Sub SMA package footprint and electrical performance. Selection among these variants is based on inventory availability and manufacturing date code requirements.

For Extended Temperature Operation:

ES1GLW provides an extended operating temperature range (-55°C to 175°C) compared to the ES1GL (-55°C to 150°C). This part is suitable for applications requiring higher thermal margins. However, ES1GLW uses the SOD-123W package instead of Sub SMA, requiring PCB layout modification and assembly process validation.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and environmental regulations. All parts carry REACH Unaffected status and EAR99 export classification, matching the original ES1GL specifications.

Inventory and Availability:

ES1GL M2G (986 pcs), ES1GL MHG (674 pcs), ES1GL MQG (702 pcs), ES1GL MTG (1000 pcs), ES1GL RFG (948 pcs), ES1GL RHG (782 pcs), ES1GL RQG (671 pcs), ES1GL RTG (804 pcs), and ES1GL RUG (1155 pcs) are all in active stock. ES1GLW (20862 pcs) offers significantly higher inventory availability for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can ES1GL M2G, ES1GL MHG, ES1GL MQG, ES1GL MTG, ES1GL RFG, ES1GL RHG, ES1GL RQG, and ES1GL RTG be used interchangeably with ES1GL?

A: Yes. These parts are parametric equivalents with identical electrical specifications (400 V, 1 A, 35 ns recovery time, 1.3 V forward voltage) and the same Sub SMA package. They differ only in manufacturing date codes or internal lot designations. Direct substitution is supported without circuit modification.

Q: What is the difference between ES1GL and ES1GLW?

A: ES1GLW differs in two aspects: package type (SOD-123W instead of Sub SMA) and operating temperature range (-55°C to 175°C versus -55°C to 150°C). Electrical performance is identical. ES1GLW substitution requires PCB layout changes to accommodate the different package footprint.

Q: Why is the ES1GL marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Existing inventory remains available for production support and maintenance applications. For new product development, selection from the active substitute parts (ES1GL M2G, ES1GL MHG, ES1GL MQG, ES1GL MTG, ES1GL RFG, ES1GL RHG, ES1GL RQG, ES1GL RTG, ES1GL RUG, or ES1GLW) is recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard surface mount assembly and environmental regulations.

Q: Which substitute part should I select for high-volume production?

A: ES1GLW offers the highest inventory (20862 pcs) and is suitable for high-volume applications. If Sub SMA package compatibility is required, ES1GL RUG (1155 pcs) provides the highest availability among the Sub SMA variants.

Q: Can ES1GL be used in applications requiring temperatures above 150°C?

A: No. The ES1GL operating temperature range is -55°C to 150°C. For applications requiring operation up to 175°C, ES1GLW is the appropriate substitute, provided the SOD-123W package is compatible with the PCB design.

Q: What is the reverse recovery time specification, and why is it important?

A: Reverse recovery time (trr) is 35 ns for all listed parts. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking. The fast recovery characteristic (≤ 500ns) makes these parts suitable for switching applications where rapid turn-off is required.

Q: Are there any differences in capacitance between ES1GL and its substitutes?

A: ES1GL and most Sub SMA variants specify 8 pF @ 4V or 1V, 1 MHz. ES1GLW specifies 20 pF @ 4V, 1 MHz. This difference reflects the different package geometry and does not affect functional equivalence for standard rectification applications.
