ES1A General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The ES1A is a general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or specific packaging requirements while maintaining identical functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES1A are identified based on strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage of 50 V maximum
• Current Rating: Average rectified current of 1 A
• Forward Voltage Drop: 950 mV maximum at 1 A forward current
• Recovery Characteristics: Fast recovery classification with 35 ns reverse recovery time
• Package Compatibility: DO-214AC (SMA) surface mount package
• Operating Temperature Range: -55°C to 150°C junction temperature
• Compliance Standards: RoHS3 compliance and REACH unaffected status

Substitute parts must match all electrical parameters within the specified tolerances and maintain identical mechanical compatibility with the DO-214AC footprint. Packaging format (bulk versus tape & reel) does not affect electrical substitutability but may influence procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

The ES1A_R1_00001 manufactured by Panjit International Inc. is a direct parametric equivalent to the ES1A. Both components maintain Active product status and satisfy RoHS3 compliance requirements. The substitute part demonstrates equivalent electrical performance across all critical rectification parameters: reverse voltage rating, forward current capacity, forward voltage drop, and recovery time characteristics.

The ES1A_R1_00001 exhibits lower reverse leakage current (1 µA versus 5 µA at 50 V) and reduced junction capacitance (7 pF versus 16 pF at 4 V, 1 MHz), both of which represent improved performance characteristics relative to the primary part. These differences do not compromise substitutability and may provide operational advantages in applications sensitive to leakage or capacitive loading.

Both components are supplied in DO-214AC (SMA) surface mount packages with identical footprints and mounting requirements. The primary distinction is packaging format: the ES1A is supplied in standard packaging, while the ES1A_R1_00001 is available in tape & reel format. This difference affects procurement and automated assembly processes but does not alter electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ES1A_R1_00001 be used as a direct replacement for ES1A in existing designs?

A: Yes. The ES1A_R1_00001 meets all electrical specifications of the ES1A, including voltage rating, current capacity, forward voltage drop, and recovery time. Both components use identical DO-214AC (SMA) surface mount packages with matching footprints and pin configurations.

Q: What are the differences between ES1A and ES1A_R1_00001?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Panjit International Inc.) and packaging format (standard versus tape & reel). Electrically, the ES1A_R1_00001 exhibits lower reverse leakage current and reduced junction capacitance, both favorable characteristics. All critical rectification parameters are equivalent.

Q: Does the lower reverse leakage current of ES1A_R1_00001 affect circuit performance?

A: Lower reverse leakage current (1 µA versus 5 µA) represents improved performance. This characteristic reduces power dissipation in reverse bias conditions and may benefit applications with stringent leakage requirements. The difference does not create incompatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ES1A and ES1A_R1_00001 are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of tape & reel packaging for ES1A_R1_00001?

A: Tape & reel packaging is a standard format for automated assembly processes. It does not affect electrical or mechanical compatibility. Selection between standard and tape & reel packaging depends on assembly methodology and procurement workflow requirements.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: Yes. Both components are classified as fast recovery diodes with 35 ns reverse recovery time, suitable for switching applications. The identical recovery characteristics ensure equivalent performance in high-frequency rectification circuits.

Q: What is the operating temperature range for both parts?

A: Both ES1A and ES1A_R1_00001 operate across a junction temperature range of -55°C to 150°C, providing equivalent thermal performance across industrial and commercial temperature environments.

Q: Are there any moisture sensitivity concerns with these components?

A: No. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Standard handling and storage procedures apply without special moisture control requirements.
