S1D General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The S1D 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. This component is classified as Active product status and utilizes standard recovery technology. Substitute parts are identified when equivalent electrical ratings and mechanical compatibility are maintained across the specified parameter set, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1D are identified based on strict equivalence in the following critical parameters:

• Voltage Rating: DC reverse voltage of 200 V maximum
• Current Rating: Average rectified current of 1 A
• Package Type: Surface mount DO-214AC/SMA configuration
• Mounting Technology: Surface mount compatibility
• Operating Temperature Range: Junction temperature capability within specified limits

The ES1D from EVVO Semi meets these core electrical and mechanical requirements. While the ES1D exhibits faster recovery characteristics (35 ns versus 1.5 µs) and lower forward voltage (1 V versus 1.1 V at 1 A), these represent performance enhancements rather than deviations from the substitution criteria. Both devices maintain identical voltage and current ratings with compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

S1D Selection: The S1D remains the primary choice when standard recovery characteristics and the specified forward voltage profile are required. This device is Active status with established supply availability.

ES1D Selection: The ES1D is a direct substitute when faster recovery performance and lower forward voltage dissipation are beneficial to circuit operation. The ES1D provides ROHS3 compliance and an extended lower operating temperature limit (-55°C versus -50°C). Higher reverse leakage current (5 µA versus 1 µA at 200 V) must be evaluated in applications with stringent leakage requirements.

Both devices are Active status products with confirmed inventory availability. Selection between S1D and ES1D depends on specific application requirements regarding recovery speed, forward voltage characteristics, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the ES1D replace the S1D in existing designs?

A: Yes. Both devices share identical voltage (200 V) and current (1 A) ratings with compatible DO-214AC/SMA surface mount packaging. The ES1D exhibits superior recovery speed and lower forward voltage, which are performance enhancements. Applications must evaluate reverse leakage current specifications if leakage-sensitive.

Q: What is the primary difference between S1D and ES1D?

A: The ES1D features fast recovery technology (35 ns) compared to the S1D standard recovery (1.5 µs), resulting in lower forward voltage (1 V versus 1.1 V at 1 A). Both maintain identical voltage and current ratings.

Q: Are the packages physically identical?

A: Yes. Both the S1D and ES1D use the DO-214AC/SMA surface mount package, enabling direct board-level substitution without layout modifications.

Q: Does the ES1D require design re-qualification?

A: Electrical compatibility is maintained across voltage, current, and temperature parameters. Design re-qualification depends on application-specific requirements regarding recovery time, forward voltage, and reverse leakage characteristics.

Q: What is the reverse leakage difference between these devices?

A: The S1D exhibits 1 µA reverse leakage at 200 V, while the ES1D exhibits 5 µA at 200 V. Applications with strict leakage requirements must account for this difference.

Q: Is the ES1D RoHS compliant?

A: Yes. The ES1D is ROHS3 compliant. The S1D RoHS status is listed as not applicable.
