BAV70

Overview

The Diotec Semiconductor BAV70 is a high-speed switching diode array featuring two common cathodes in an SOT-23 surface-mount package. It provides a repetitive peak reverse voltage of up to 100 V and a maximum average forward current of 215 mA per diode. The device exhibits a very fast reverse recovery time of less than 4 ns, making it suitable for rapid signal processing applications. With a power dissipation rating of 350 mW and a junction temperature range from -55°C to +150°C, the component ensures reliable operation in industrial environments.

Feature Summary

• High-speed switching capability with minimal reverse recovery delay
• Dual diode configuration with a shared common cathode terminal
• Compliant with RoHS directives and REACH regulations

Applications

• High-speed signal processing circuits
• General-purpose rectifying tasks
• Rapid electronic switching operations

Procurement Notes

Verify the specific ordering suffix when purchasing to confirm the intended quality grade. The absence of a suffix indicates an industrial-grade component, while the -C suffix denotes commercial grade. Additionally, the -Q and -AQ suffixes identify parts that are AEC-Q101 compliant or qualified, respectively. Ensure the selected variant aligns with your project's reliability requirements before finalizing procurement.

Selection Notes

Select the BAV70 for designs requiring compact dual-diode solutions with fast switching speeds. The standard version suits general industrial needs, whereas automotive applications should utilize the AEC-Q101 qualified variants. Consider the thermal resistance and power dissipation limits when designing heat management strategies for densely packed circuit boards.

Part Context

This component belongs to Diotec's SMD small signal diode family, which includes the BAS16 single diode and the BAW56 common anode array. All three devices share similar mechanical dimensions and packaging standards but differ in internal configurations and specific electrical ratings. This grouping allows designers to choose the optimal topology for their specific circuit requirements.
