2N4237 Description

Short technical summary and product information.

The 2N4237 is a single NPN bipolar junction transistor designed for general purpose switching and amplification. It features a collector-emitter voltage rating of 40V, continuous collector current of 1A, and maximum power dissipation of 1W. The DC current gain (hFE) is a minimum of 30 at Ic=500mA and Vce=1V, and the collector-emitter saturation voltage is typically 600mV at Ib=100mA and Ic=1A.

 

This transistor is housed in a TO-205AD / TO-39-3 metal can package with through-hole mounting, suitable for rugged applications that require mechanical stability. The operating junction temperature range spans from -65°C to 200°C, providing reliable performance across extreme environments.\n\nTypical design contexts include medium current driver circuits, relay and solenoid drivers, and audio preamplifier stages where moderate gain and power handling are needed. The device is compatible with standard solder assembly processes.
