ES1D-AQ

Single Diodes Overview

The ES1D-AQ is a general-purpose fast recovery rectifier diode manufactured by Diotec Semiconductor, designed for surface-mount applications in the DO-214AC (SMA) package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 1 A. The device exhibits a typical forward voltage drop of 1.3 V at 1 A and a maximum reverse leakage current of 5 µA at its rated voltage. With a reverse recovery time of 50 ns, it supports switching frequencies up to 1 kHz. Operating within a junction temperature range of -55°C to 150°C, it meets automotive reliability standards including AEC-Q101 qualification.

Single Diodes Procurement Notes

Verify that the ordered component carries the specific "-AQ" suffix to ensure compliance with AEC-Q101 automotive qualification requirements. Confirm the package type matches the required DO-214AC footprint during integration. Request the official datasheet to validate electrical parameters against specific design constraints before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component when automotive reliability is mandatory for low-voltage rectification tasks. The 100 V rating provides adequate margin for 12 V automotive systems. Ensure the PCB layout accommodates the SMA package dimensions and thermal dissipation needs associated with 1 A continuous current operation in enclosed environments.

Single Diodes Part Context

This part belongs to the ES1 series of fast recovery diodes from Diotec Semiconductor. The family includes variants with different voltage ratings such as ES1B through ES1K. The ES1D specifically targets 100 V applications. The AQ designation indicates adherence to strict automotive quality control processes distinct from standard industrial grade components.

Single Diodes Replacement Considerations

Cross-reference with other AEC-Q101 qualified SMA packages offering identical 100 V and 1 A ratings. Verify pinout compatibility and thermal resistance values to ensure seamless substitution without circuit redesign.
