Description
The FMMT413 is a NPN silicon planar bipolar transistor optimized for
avalanche mode operation. Tight process control and low inductance
packaging combine to produce high current pulses with fast edges, ideal
for laser diode driving.
Features
• Avalanche mode operation
• 50A peak avalanche current
• Low inductance packaging
Applications
• Laser LED drivers
• Fast edge generation
• High speed pulse generators
