2N3439UA Description

Short technical summary and product information.

The 2N3439UA is an NPN bipolar junction transistor manufactured by Microchip Technology. It features a maximum collector-emitter voltage (Vce) of 350V and a maximum collector current (Ic) of 1A, making it suitable for medium-voltage switching and amplification applications.

 

With a DC current gain (hFE) of at least 40 at 20mA collector current and 10V Vce, and a low collector-emitter saturation voltage of 500mV at 4mA base current and 50mA collector current, this transistor offers efficient switching performance. The device can dissipate up to 800mW of power.

 

The 2N3439UA is housed in a surface-mount 4-SMD no-lead package, allowing for compact PCB designs. It operates over a junction temperature range of -65°C to 200°C, suitable for harsh environments. The part is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
