ES1D General Purpose Rectifier Diode - Equivalent & Substitute Parts

Part Overview

The ES1D is a general purpose rectifier diode manufactured by Diotec Semiconductor, rated for 200 V DC reverse voltage and 1 A average rectified current in a surface mount SMA/DO-214AC package. The device is classified as Active product status with fast recovery characteristics suitable for standard rectification applications. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1D is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AC, SMA form factor

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Supplier Device Package: SMA/DO-214AC compatible

The substitute part ES1D_R1_00001 manufactured by Panjit International Inc. meets all electrical and mechanical equivalence requirements. Both parts share identical voltage and current ratings, fast recovery speed classification, and identical package specifications. Variations in forward voltage (950 mV vs. 920 mV), reverse recovery time (35 ns vs. 15 ns), and reverse leakage current (1 µA vs. 5 µA) remain within acceptable tolerance ranges for general purpose rectification applications and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the ES1D (Diotec Semiconductor) and ES1D_R1_00001 (Panjit International Inc.) are Active product status components suitable for direct substitution in general purpose rectification circuits. Selection between these parts is determined by application-specific requirements and supply chain considerations.

The ES1D_R1_00001 offers ROHS3 compliance and REACH Unaffected status, providing regulatory advantage in applications subject to these compliance frameworks. The Panjit part also demonstrates superior reverse leakage characteristics (1 µA vs. 5 µA) and extended lower temperature rating (-55°C vs. -50°C), which may be beneficial in temperature-sensitive or low-leakage applications.

The Diotec ES1D provides superior reverse recovery time performance (15 ns vs. 35 ns) and lower forward voltage drop (920 mV vs. 950 mV), which may be advantageous in high-frequency switching or efficiency-critical applications.

Packaging availability differs between manufacturers: Diotec supplies Cut Tape and Digi-Reel formats, while Panjit supplies Tape & Reel format. Procurement requirements should align with available packaging options.

Frequently Asked Questions (FAQ)

Q: Can ES1D_R1_00001 be used as a direct replacement for ES1D in existing designs?

A: Yes. Both parts share identical voltage ratings (200 V), current ratings (1 A), speed classification (Fast Recovery ≤ 500ns), and package specifications (DO-214AC, SMA). Electrical parameter variations fall within acceptable tolerance ranges for general purpose rectification applications.

Q: What are the differences in forward voltage between these parts?

A: The ES1D specifies 920 mV maximum forward voltage at 1 A, while the ES1D_R1_00001 specifies 950 mV maximum at 1 A. This 30 mV difference represents approximately 3.3% variation and is typical among different manufacturers' implementations of equivalent rectifier diodes.

Q: Does the reverse recovery time difference affect circuit performance?

A: The ES1D exhibits 15 ns reverse recovery time while the ES1D_R1_00001 exhibits 35 ns. Both remain within the Fast Recovery classification (≤ 500ns). The difference is relevant only in high-frequency switching applications where switching losses are critical. For standard rectification applications, both parts perform equivalently.

Q: Are there compliance or certification differences between these parts?

A: The ES1D_R1_00001 carries ROHS3 compliance and REACH Unaffected status. The ES1D lists RoHS Status as Not Applicable and REACH Status as Vendor Undefined. Applications requiring regulatory compliance should specify the Panjit ES1D_R1_00001 part.

Q: What packaging formats are available for each part?

A: The Diotec ES1D is supplied in Cut Tape (CT) and Digi-Reel® formats. The Panjit ES1D_R1_00001 is supplied in Tape & Reel (TR) format. Procurement specifications should align with available packaging options and assembly equipment requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical DO-214AC/SMA surface mount package specifications and mounting type. PCB footprints and reflow profiles are compatible between the two parts.

Q: Which part has better reverse leakage characteristics?

A: The ES1D_R1_00001 demonstrates lower reverse leakage current at 1 µA @ 200 V compared to the ES1D at 5 µA @ 200 V. This characteristic is advantageous in applications requiring minimal leakage current, such as precision analog circuits or high-impedance applications.

Q: What is the temperature operating range for each part?

A: The ES1D operates from -50°C to 150°C junction temperature. The ES1D_R1_00001 operates from -55°C to 150°C junction temperature. The Panjit part provides 5°C additional lower temperature capability.
