Overview
The LC945P is a general-purpose NPN bipolar junction transistor manufactured by onsemi, housed in a TO-92 three-lead through-hole package. It features a maximum collector current of 150 mA and a collector-emitter voltage rating of 50 V. The device has a collector-base voltage of 60 V and an emitter-base voltage of 5 V. Maximum power dissipation is 250 mW, with a minimum DC current gain (hFE) of 40. The transition frequency is specified at 1 MHz, and the maximum operating temperature reaches 150°C.
Feature Summary
- NPN polarity configuration for standard switching and amplification applications
- Through-hole TO-92 package design for reliable board mounting
- General-purpose performance characteristics suitable for low-power circuits
Applications
- General purpose signal amplification
- Low-power switching circuits
- Audio pre-amplifier stages
Procurement Notes
Verify component authenticity and datasheet alignment before integration. Confirm that the TO-92 package dimensions match the target PCB footprint. Ensure thermal management strategies account for the 250 mW dissipation limit under expected load conditions. Check for any specific handling requirements during assembly to maintain electrical integrity.
Selection Notes
Select this component when a general-purpose NPN transistor with moderate voltage ratings is required. The 50 V collector-emitter voltage and 150 mA current capacity define its operational boundaries. Consider the TO-92 form factor for prototyping or low-volume production where through-hole technology is preferred over surface-mount alternatives.
Part Context
The LC945P belongs to the broader family of small-signal transistors offered by onsemi. It serves as a discrete semiconductor solution within the company's portfolio of passive and active components. This part represents a standard industry-compatible device designed for widespread electronic manufacturing use cases.
Replacement Considerations
Public records indicate the LC945P status is obsolete with a last time buy date of June 30, 2006. No direct substitute part numbers are confirmed in the provided documentation. Engineers should evaluate alternative general-purpose NPN transistors from other manufacturers or newer onsemi series for replacement.
