BAV19

Overview

The BAV19 is a superfast recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 250 mA and a peak forward surge current (IFSM) of 5 A. The device has a maximum repetitive reverse voltage (VRRM) of 650 V. Key electrical characteristics include a forward voltage (VF) of less than 1.0 V at 0.1 A, a leakage current (IR) below 100 nA at 25°C, and a typical junction capacitance of 5 pF. The reverse recovery time (trr) is under 50 ns. Operating temperatures range from -50°C to +200°C for both junction and storage.

Feature Summary

• Superfast recovery performance with reverse recovery time under 50 ns
• High voltage capability up to 650 V repetitive reverse voltage
• Extended thermal operation supporting junction temperatures up to 200°C
• Low leakage current ensuring minimal power loss in high-impedance states

Applications

• High-frequency switching circuits
• Fast recovery rectification in power supplies
• Snubber circuits requiring rapid discharge
• Clamping applications in high-voltage environments

Procurement Notes

Verify the specific package type and marking code against the official Diotec Semiconductor datasheet before ordering. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributor. Ensure that the requested quantity matches standard factory packaging configurations. Cross-reference the part number suffixes to guarantee exact electrical matching for critical circuit designs.

Selection Notes

Select this component when circuit design demands fast switching speeds combined with high voltage blocking capabilities. The low junction capacitance makes it suitable for high-frequency signal processing. Evaluate the thermal resistance and ambient temperature conditions to ensure the 200°C junction limit is not exceeded during continuous operation. Compare the 50 ns recovery time against slower alternatives to determine efficiency gains in the target application.
