. . . GA300A GB300A Commercial Nanosecond Switching GA3OL GB30L Planar GA301A GB301A FEATURES DESCRIPTION © Rise lime: luns ‘The Microsemi Nanosecond Thyristor Switch combines the tum-on speed of logic level © Delay Time: 10ns ‘transistors with the high current switching capability inherent in SCRs. With this device ‘© Recovery Time: 0.5us engineers can now design circuits capable of switching pulse currents of 1A in less than © Pulse Current: to 100A 10ns or up to 30A in less than 20ns. ‘© Turn-on with 20ns, 10mA gate pulse " s: gate pi ‘The GA300, GB300 Series is specifically designed for use as switching element in high ‘speed laser diode pulse drivers. Other applications include electronic crowbars, harmonic wave-form generators, line drivers and general purpose replacements for avalanche transistors. For applications requiring higher voltage levels, Microsemi has developed ‘several “series string” circuits which allow the series connection of an unlimited number of devices for voltages as high as 2000V with no significant decrease in speed. The circuits are described in Microsemi's Design Note #14. | 8 | ABSOLUTE MAXIMUM RATINGS as0o gaaot 8300 ens01 anseon Every cooeen enact Repetitive Peak Off-State Voltage, Vory 6ov. 100v. 60V. 100V Repetitive Peak On-State Current, Ira, up to 100A up to 100A Peak Gate Current, ley 250mA ‘250mA Avetage Gate Current, Ierayy Zama Suma Reverse Gate Current, log 7 3mA 3mA Reverse Gate Voltage, Vg . 5V. 5V.
