KSD1221OTU Description

Short technical summary and product information.

The KSD1221OTU is an NPN epitaxial silicon transistor designed for low-frequency power amplification. It features a maximum collector-emitter voltage of 60V and a continuous collector current of 3A, with a low collector-emitter saturation voltage of 1V at 3A/0.3A.

 

This transistor has a DC current gain (hFE) ranging from 60 to 300 at 5V/0.5A. The current gain bandwidth product (fT) is 3MHz at 5V/0.5A. It can dissipate up to 20W when the case temperature is 25°C, or 1W when the ambient temperature is 25°C.

 

The KSD1221OTU is housed in an I-PAK (TO-251-3 Short Leads, IPak, TO-251AA) package and is designed for through-hole mounting. Its operating junction temperature is rated up to 150°C.

 

This component is a complement to the KSB906 and is suitable for applications requiring low collector-emitter saturation voltage.
