SD1540
SD1540 is RF & MICROWAVE TRANSISTORS manufactured by STMicroelectronics.
DESCRIPTION
The SD1540 is a gold metallized silicon, NPN power transistor designed for applications requiring high peak power and low duty cycles such as IFF, DME and TACAN. The SD1540 is packaged in a metal/ceramic package with internal input/output matching resulting in improved broadband performance and a low thermal resistance.
