SMUN5330DW1T1G

Overview

The SMUN5330DW1T1G is a digital transistor array manufactured by onsemi, featuring one NPN and one PNP pre-biased bipolar junction transistor within a single SOT-363 (SC-88) surface-mount package. The device integrates monolithic bias resistor networks to simplify circuit design. It supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Key electrical parameters include a base resistance (R1) of 1 kΩ and an emitter resistance (R2) of 1 kΩ for both transistors. The unit offers a maximum power dissipation of 250mW and meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistors to replace discrete components
• Utilizes compact SOT-363 packaging to minimize printed circuit board footprint
• AEC-Q100 qualified for reliability in automotive electronic environments

Applications

• Automotive logic switching circuits requiring dual polarity control
• Battery management systems utilizing low-power signal processing

Procurement Notes

Verify the specific suffix DW1T1G against official onsemi documentation to confirm pinout compatibility and manufacturing site origin. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure ordering quantities align with standard reel or cut tape configurations provided by authorized distributors.

Selection Notes

Select this component when a dual-channel solution combining NPN and PNP switching capabilities is required in a minimal footprint. The integrated 1kΩ bias resistors reduce external component count compared to discrete BJT arrangements. Verify that the 50V voltage rating and 100mA current capacity meet the specific load requirements of the target application circuit.
