BUZ21 Description

Short technical summary and product information.

The BUZ21 is an N-Channel enhancement-mode MOSFET manufactured by Harris Semiconductor. It is designed for medium-power switching and amplification applications.

 

Key electrical specifications include a drain-source breakdown voltage of 100V and a continuous drain current rating of 21A at case temperature. The device has a maximum on-resistance of 85mOhm when driven with 10V gate-to-source voltage at 13A drain current. The maximum gate threshold voltage is 4V at 1mA drain current. Input capacitance is 1300pF at 25V drain-source voltage.

 

The BUZ21 uses standard MOSFET (Metal Oxide) technology and is housed in a TO-220-3 through-hole package with a TO-220AB supplier device package. This package is suitable for PCB mounting and allows for heatsink attachment for thermal management.
