SMUN5216DW1T1G

Overview

The SMUN5216DW1T1G is a dual NPN Bias Resistor Transistor (BRT) from onsemi, housed in an SOT-363 package. It integrates two NPN transistors with monolithic bias networks, each comprising a series base resistor and a base-emitter resistor. Key electrical parameters include a collector-emitter voltage of 50 Vdc, continuous collector current of 100 mAdc, and DC current gain ranging from 160 to 350 at 5 mA. The input resistors are typically 4.7 kΩ, with a maximum value of 6.1 kΩ. Total device dissipation is 256 mW at 25°C for one junction heated.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistor networks to replace discrete components
• Reduces board space and component count by combining transistors and resistors into a single device
• Simplifies circuit design through pre-biased configuration

Applications

• Automotive applications requiring AEC-Q101 qualification and PPAP capability
• Low power surface mount applications where board space is limited
• Digital switching circuits requiring simplified biasing

Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's current documentation before procurement. Confirm that the device meets all required automotive qualification standards if applicable. Ensure compatibility with existing PCB footprints for the SOT-363 package. Check for any discontinuation notices or recommended replacements for new designs.

Selection Notes

Select this component when a dual NPN digital transistor with integrated bias resistors is needed. Consider the 4.7 kΩ typical input resistance and 50 V voltage rating for circuit compatibility. Evaluate thermal dissipation requirements based on the operating ambient temperature and junction heating conditions. Verify package availability and lead times for production needs.
