MUN5333DW1T1G

Overview

The onsemi MUN5333DW1T1G is a complementary digital transistor array featuring one NPN and one PNP bias resistor transistor (BRT) in a SOT-363 (SC-88) surface-mount package. It provides a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device integrates typical base resistors of 4.7 kOhms with an emitter resistor ratio of 0.1, reducing external component count. It operates within a temperature range of -55 °C to +150 °C, with a power dissipation rating of 187 mW.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors for simplified circuit design.
• Utilizes a compact six-pin SOT-363 surface-mount package to minimize board space requirements.
• Offers high thermal stability with a maximum operating junction temperature of +150 °C.

Applications

• Switching applications in portable consumer electronics
• Logic level translation and interface circuits
• Driver stages for low-power loads in embedded systems

Procurement Notes

Verify the complete part number including the suffix 'DW1T1G' to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines specified in the datasheet to prevent package damage during soldering processes.

Selection Notes

Select this component when a complementary NPN/PNP pair with integrated biasing is required in a minimal footprint. Compare internal resistor values against specific logic drive requirements to ensure adequate base current. Evaluate thermal performance under expected load conditions to verify that power dissipation remains within the 187 mW limit. Consider alternative pin-compatible variants if different resistor ratios are needed for specific gain characteristics.
