Overview
The BC846BW/ZLF is a silicon NPN general-purpose bipolar junction transistor manufactured by Nexperia, distributed under the NXP Semiconductors brand. It is housed in a surface-mount SOT-323 (SC-70) package with three terminals. Key electrical specifications include a maximum collector-emitter voltage of 65 V, a collector-base voltage of 80 V, and an emitter-base voltage of 6 V. The device supports a continuous DC collector current of 100 mA and dissipates up to 200 mW of power. It features a transition frequency of 100 MHz and operates within a temperature range of -65°C to +150°C.
Feature Summary
- High DC current gain for efficient signal amplification
- Low saturation voltage for improved switching efficiency
- Compact SOT-323 surface-mount packaging
Applications
- General-purpose switching applications
- Small-signal amplification circuits
- Driver stages for logic interfaces
Procurement Notes
Verify the manufacturer designation on the component marking, as Nexperia produces this part while it may be listed under NXP distribution channels. Confirm the suffix ZLF indicates lead-free compliance and RoHS adherence. Ensure the ordering code matches the specific tape-and-reel or cut-tape format required for your assembly line equipment.
Selection Notes
Select this component when a low-power NPN transistor with high gain is required in a small footprint. Compare the 100 mA current limit against load requirements. Consider the SOT-323 thermal characteristics for heat dissipation. Verify that the 65 V breakdown voltage exceeds the circuit's peak operating voltage to ensure reliability.
Part Context
This component belongs to the BC846 series of NPN transistors designed for general-purpose use. It serves as a compact alternative to larger packages like SOT-23, offering similar electrical performance in a reduced physical size. The series is widely used in consumer electronics and industrial control boards where space constraints are critical.
Replacement Considerations
The BC846B is a compatible substitute with identical electrical ratings. The BC846C variant offers higher minimum gain but shares the same package and voltage limits. Verify pinout compatibility before substitution.
