BAS70-00-HE3-18

Single Diodes Overview

The BAS70-00-HE3-18 is a single small signal Schottky diode manufactured by Vishay General Semiconductor - Diodes Division. It features a very low turn-on voltage and fast switching capabilities, housed in an SOT-23 surface-mount package. The device incorporates a PN junction guard ring for protection against excessive voltages such as electrostatic discharges. It is AEC-Q101 qualified and RoHS-compliant. Key electrical parameters include a repetitive peak reverse voltage of 70 V, a forward continuous current of 200 mA, and a maximum leakage current of 100 nA at 50 V.

Single Diodes Feature Summary

• Features a very low turn-on voltage and fast switching characteristics
• Incorporates a PN junction guard ring to protect against excessive voltage and electrostatic discharge
• Manufactured with HE3 technology, ensuring compliance with automotive reliability standards

Single Diodes Applications

• Automotive electronics requiring AEC-Q101 qualification
• General purpose rectification in low voltage circuits
• High speed switching applications

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm the packaging configuration, as the -18 suffix indicates tape and reel packaging on a 13-inch reel. Ensure that the HE3 designation is required for your application, as it denotes AEC-Q101 qualification compared to the commercial grade E3 variant. Confirm component authenticity through authorized distribution channels to guarantee adherence to Vishay's manufacturing specifications.

Single Diodes Selection Notes

Select this component when a single Schottky diode with AEC-Q101 automotive qualification is required in an SOT-23 package. It is suitable for applications demanding low forward voltage drop and high-speed performance. Consider the thermal resistance of 500 K/W and power dissipation limits of 200 mW during circuit design. Compare with other BAS70 models if dual configurations or different pinouts are needed.

Single Diodes Part Context

This part belongs to the BAS70 series of small signal Schottky diodes from Vishay Semiconductors. The series includes single and dual configurations such as common cathode and common anode types. The HE3 variant specifically targets automotive applications due to its enhanced reliability and qualification status, distinguishing it from standard commercial grade devices within the same family.

Single Diodes Replacement Considerations

BAS70-00-E3-18 serves as a commercial grade alternative without AEC-Q101 qualification. Other single Schottky diodes in the SOT-23 package may be considered if automotive qualification is not mandatory.

Single Diodes FAQ

What is the function of the PN junction guard ring in this device?

The PN junction guard ring protects the device against excessive voltages, such as those encountered during electrostatic discharge events.

How does the HE3 suffix differ from the E3 suffix in this product line?

The HE3 suffix indicates that the device is RoHS-compliant and AEC-Q101 qualified for automotive applications, whereas the E3 suffix denotes a RoHS-compliant commercial grade device.
