RB731UTW_R1_00001

Overview

The RB731UTW_R1_00001 is a surface mount triple Schottky diode manufactured by Panjit International Inc. It houses three electrically-isolated Schottky diodes in an SOT-363 plastic package. Key electrical ratings per diode include a maximum repetitive reverse voltage (VRRM) of 40V and an average rectified forward current (IO) of 30mA. The device features low reverse leakage current, guaranteed to be less than 0.98 µA at 25V. Thermal characteristics specify a junction-to-ambient thermal resistance (θJA) of 52 °C/W. The component operates within a junction temperature range of -55°C to +150°C.

• Personal Digital Assistants (PDAs)

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The suffix R1 indicates Tape and Reel packing on a 7-inch plastic reel. Confirm compliance requirements such as RoHS status and halogen-free material specifications against project standards. Ensure the lot number is recorded for tracking purposes as Panjit uses lot numbers as the primary tracking base.

Selection Notes

Select this component when board space is limited due to its small SOT-363 footprint. It is suitable for applications requiring multiple isolated Schottky diodes without increasing the circuit board area. Consider the 40V reverse voltage rating and 30mA current capacity to ensure they meet the specific circuit requirements. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the RB731UTW series of surface mount triple Schottky diodes from Panjit. The series is designed for high-density electronic assemblies where minimizing component size is critical. The RB731UTW variant specifically offers three isolated channels within a single six-pin package, providing a compact solution for signal processing or protection circuits in portable consumer electronics.

Replacement Considerations

Direct substitutes must match the SOT-363 package, 40V reverse voltage, and triple isolated Schottky configuration. Verify pinout compatibility and thermal resistance values before substitution. Cross-reference datasheets for equivalent electrical parameters such as forward voltage and reverse leakage current to ensure functional parity in the specific application circuit.
