Overview
The BC846AWT1 is an NPN silicon general-purpose transistor from the onsemi BC846 series, housed in a SC-70 (SOT-323) surface-mount package. It features a collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device offers a minimum DC current gain of 110 at IC = 10 mA and a transition frequency of 100 MHz. Total power dissipation is rated at 150 mW with a junction-to-ambient thermal resistance of 833 °C/W. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Designed for low-power surface mount applications using an ultra-small SC-70/SOT-323 plastic package.
- Features epitaxial silicon planar construction suitable for automatic insertion.
- Provides high DC current gain and low collector-emitter saturation voltage.
Applications
- General purpose amplifier circuits
- Switching applications in portable equipment
- AF input stages and driver applications
Procurement Notes
Verify the specific ordering suffix 'G' if lead-free compliance is required, as standard versions may differ. Confirm the tape and reel quantity matches production needs, typically 3,000 units per reel for this marking code. Ensure the component marking '1A' corresponds to the BC846AWT1 variant during incoming inspection.
Selection Notes
Select the BC846AWT1 when a 65 V collector-emitter breakdown voltage is necessary, distinguishing it from the lower-voltage BC847 and BC848 variants within the same series. Consider the 150 mW power dissipation limit and thermal resistance for heat management in dense PCB layouts. Verify that the SOT-323 footprint aligns with existing board space constraints.
Part Context
This component belongs to the BC846, BC847, and BC848 series of NPN general-purpose transistors manufactured by onsemi. These devices share the same physical SC-70 package but are differentiated by their voltage ratings: 65 V for BC846, 45 V for BC847, and 30 V for BC848. They serve as complementary small-signal alternatives to larger packages like SOT-23.
Replacement Considerations
Compatible substitutes include BC846BWT1 and BC846CWT1 from onsemi, which offer higher current gain ranges. Cross-manufacturer equivalents such as Nexperia's BC846AW or Panasonic's equivalent parts should be verified for pinout compatibility and electrical parameter matching.
