BAW56-HE3_A-08

Diode Arrays Overview

The Vishay BAW56-HE3_A-08 is a silicon epitaxial planar switching diode featuring a dual common anode configuration in an SOT-23 surface-mount package. It operates with a repetitive peak reverse voltage of 70 V and a continuous forward current of 350 mA. The device exhibits a maximum reverse recovery time of 6 ns and low junction-to-ambient thermal resistance of 460 K/W on FR-4. Electrical characteristics include a forward voltage of up to 1.25 V at 150 mA and minimal reverse leakage current of 100 nA at 70 V.

Diode Arrays Feature Summary

• Fast switching performance with a reverse recovery time of 6 ns
• Dual common anode circuit configuration for compact integration
• AEC-Q101 qualified for automotive reliability standards
• RoHS-compliant construction using UL 94 V-0 flammability rated molding compound

Diode Arrays Applications

• High-speed signal switching circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• General purpose rectification in consumer electronics
• Clamping and protection applications in low-voltage logic interfaces

Diode Arrays Procurement Notes

Verify the specific HE3_A suffix confirms AEC-Q101 qualification status before procurement, as standard E3 variants lack this certification. Confirm the -08 packaging code corresponds to the required 3000-unit reel quantity. Ensure design reviews account for the specified thermal resistance values under actual board layout conditions rather than infinite heatsink assumptions.

Diode Arrays Selection Notes

Select this component when automotive-grade reliability is mandatory alongside fast switching speeds in a small footprint. The dual common anode structure simplifies routing compared to discrete single diodes. Evaluate the 70 V reverse voltage rating against peak transient signals to ensure adequate margin. Consider the 350 mA continuous current limit for load requirements.

Diode Arrays Part Context

This part belongs to the Vishay BAW56 series of small signal switching diodes. The HE3_A variant specifically denotes AEC-Q101 qualification, distinguishing it from the commercial grade E3 versions. It utilizes silicon epitaxial planar technology within the standard SOT-23 package family designed for high-volume surface mount assembly processes.

Diode Arrays FAQ

What distinguishes the BAW56-HE3_A-08 from the BAW56-E3-08?

The HE3_A suffix indicates AEC-Q101 qualification for automotive applications, whereas the E3 suffix denotes commercial grade without this specific automotive reliability certification.

What is the maximum operating temperature range?

The device supports an operating temperature range from -55 °C to +150 °C.

How does the common anode configuration function?

The internal circuit connects the anodes of two separate diodes together, allowing a single control pin to manage the switching state of both cathodes simultaneously.
