SMUN5313DW1T3G

Overview

The SMUN5313DW1T3G is a complementary Bias Resistor Transistor (BRT) from onsemi, featuring one NPN and one PNP transistor with monolithic bias resistor networks. It integrates two resistors per transistor into a single device to replace discrete components. The unit operates within a collector-emitter voltage of 50 Vdc and supports continuous collector currents up to 100 mAdc. Packaged in SOT-363, it offers a total device dissipation of 385 mW when both junctions are heated at 25 °C. The component includes an input forward voltage rating of 40 Vdc and functions across a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Integrates dual transistors with built-in bias resistor networks to simplify circuit design
• Reduces board space and component count by replacing individual devices and external resistors
• Complementary configuration containing one NPN and one PNP element

Applications

• Automotive applications requiring AEC-Q101 qualification
• Low power surface mount applications where board space is limited
• Digital switching circuits utilizing integrated biasing

Procurement Notes

Verify the specific ordering suffix 'T3G' corresponds to the 10,000-unit tape and reel shipping format as documented in the official datasheet. Confirm that the device meets RoHS compliance and lead-free requirements for your manufacturing process. Ensure the selected package style matches the required pinout configuration for your PCB layout.

Selection Notes

Select this component when a complementary pair of digital transistors is required in a compact SOT-363 footprint. The integrated 47 kOhm resistors eliminate the need for external biasing components. Verify that the 50 V collector-emitter voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.
