MBT3946DW1T1  
Dual General Purpose  
Transistor  
The MBT3946DW1T1 device is a spin−off of our popular  
SOT−23/SOT−323 three−leaded device. It is designed for general  
purpose amplifier applications and is housed in the SOT−363−6  
surface mount package. By putting two discrete devices in one  
package, this device is ideal for low−power surface mount  
applications where board space is at a premium.
