RB731U_R1_00001

Overview

The RB731U_R1_00001 is a surface mount triple Schottky diode manufactured by Panjit International Inc. It houses three electrically-isolated Schottky diodes in an SOT-23 6L package. The device features a repetitive peak reverse voltage of 40V and a continuous reverse voltage of 40V per diode. The average rectified forward current is rated at 30mA, with a non-repetitive peak forward current of 200mA. Total power dissipation is 225mW at 25°C junction temperature. Forward voltage is typically 370mV at 10mA. Reverse leakage current is guaranteed to be less than 0.98uA at 25V. Operating junction temperature ranges from -55°C to 125°C.

Feature Summary

• Triple configuration with three electrically isolated Schottky diodes within a single compact SOT-23 6L package.
• Low reverse leakage current performance, specifically guaranteed below 0.98uA at 25V.
• Lead-free plating utilizing a 100% matte tin finish for soldering compatibility.
• Constructed using green molding compound that is halogen-free and compliant with EU RoHS directives.

Applications

• Mobile phones and accessories
• Video game console connector ports
• Personal Digital Assistants (PDAs)

Procurement Notes

Verify the specific ordering suffix _R1_00001 against the manufacturer's official documentation to confirm packaging details. The source indicates that the second code '1' corresponds to a 7-inch reel size, while 'R' denotes Tape and Reel packing. Ensure the component version matches the required Halogen-Free or RoHS specifications as defined in the datasheet's ordering information table before finalizing procurement orders.

Selection Notes

Select this component when board space is limited due to its small SOT-23 6L footprint. It is suitable for low-current rectification applications requiring high switching speeds and low forward voltage drops. The triple isolation feature allows for independent circuit paths within a single package. Verify that the 30mA average forward current rating meets the specific load requirements of the target application design.

Part Context

This part belongs to the RB731U series of surface mount triple Schottky diodes produced by Panjit International Inc. The series is designed for general-purpose rectification in portable electronics where miniaturization is critical. The R1 suffix specifies the tape and reel packaging format with a 7-inch reel size, distinguishing it from other packaging variants like the R2 suffix which uses a 13-inch reel.

Replacement Considerations

Direct substitutes must match the triple Schottky configuration, 40V reverse voltage, and SOT-23 6L package dimensions. Verify electrical parameters such as forward voltage and reverse leakage current against the original specifications to ensure circuit compatibility without modification.
