2N3506 Description

Short technical summary and product information.

The 2N3506 is a single NPN bipolar junction transistor manufactured by Microchip Technology. It belongs to the category of discrete semiconductor products and is intended for general-purpose amplification, switching, and signal conditioning in through-hole circuits.

 

Key electrical specifications include a collector-emitter voltage rating of 40V, a collector current rating of 500mA, and a power dissipation rating of 1W. The minimum DC current gain (hFE) is 40 at Ic=1.5A and Vce=2V, while the maximum collector-emitter saturation voltage is 500mV at Ib=50mA and Ic=500mA.

 

The device is supplied in a TO-205AD / TO-39-3 metal can package, also referenced as TO-39, with through-hole mounting. It operates over a junction temperature range of -65°C to 200°C, making it suitable for a wide range of temperature environments.

 

For design engineers, the 2N3506 offers a balanced combination of moderate voltage, current, and power handling in a durable metal can package. The through-hole form factor simplifies prototyping and manual assembly.
