Overview
The NSB4904DW1T2G is a digital transistor from onsemi, featuring an NPN and PNP configuration within a single SOT-323-6 surface-mount package. It integrates internal bias resistors with a typical value of 47 kOhms to simplify circuit design. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. With a minimum DC current gain (hFE) of 80, it serves as a compact solution for switching applications requiring dual polarity control in space-constrained environments.
Feature Summary
- Dual NPN/PNP configuration in a single compact package
- Integrated bias resistors reduce external component count
- Surface-mount SOT-323-6 footprint for automated assembly
Applications
- General-purpose switching circuits
- Driver stages for logic interfaces
- Battery management system control
Procurement Notes
Verify the specific suffix 'T2G' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints designed for SOT-323-6 packages. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when dual NPN and PNP switching capabilities are required in a minimal footprint. The integrated 47 kOhm resistors suit standard logic levels. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.
Part Context
This part belongs to onsemi's NSB series of digital transistors, which combine bipolar junction transistors with built-in resistor networks. The SOT-323-6 package allows for high-density mounting on printed circuit boards, making it suitable for portable electronics and compact industrial modules where board space is limited.
Replacement Considerations
Check for NSB4904DW1T1G as a potential alternative with identical electrical characteristics but different packaging quantities. Verify pinout compatibility before substitution.
