The onsemi 2N5210TA is an NPN general-purpose amplifier transistor designed for low noise and high gain applications. It operates within a collector current range of 1 µA to 50 mA. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a total device dissipation (PD) of 625 mW at 25°C. The device features a DC current gain (hFE) ranging from 200 to 600 at IC = 100 µA. It supports a junction temperature range of -55°C to +150°C and utilizes a TO-92-3 through-hole package.
Verify the specific manufacturer origin as the 2N5210 designation was originally established by Fairchild Semiconductor. Confirm that the onsemi variant meets all required datasheet specifications for breakdown voltages and thermal resistance. Ensure the TO-92-3 package configuration matches the intended board layout requirements before finalizing procurement orders.
Select this component when designing circuits requiring high gain and low noise characteristics at low bias currents. The TO-92-3 package facilitates easy integration into through-hole designs. Consider the 50 V collector-emitter rating and 625 mW power dissipation limits when determining thermal management strategies for the application environment.
The 2N5210 is a legacy NPN bipolar junction transistor widely recognized for its utility in analog signal processing. Originally developed by Fairchild Semiconductor, the part has been maintained in production by subsequent manufacturers including onsemi. It remains a standard choice for discrete amplifier designs where moderate voltage handling and high linearity are prioritized over high-power switching capabilities.
The MMBT5210 serves as a verified surface-mount equivalent offering identical electrical characteristics in a SOT-23 package.
