HCPLT251

www.datasheet4u.com 0.4 Amp Output Current IGBT Gate Drive Optocoupler Technical Data HCPL-T251 Features Supply Current (ICC): 11 mA (Max.) Supply Voltage (VCC): 10-30 V Output Current (IO): ± 0.4 A (Min.) Switching Time (tPLH/tPHL): 1 µs (Max.) Isolation Voltage (VISO): 3750 Vrms (Min.) UL 577 Recognized: File No. E55361 CSA Approved 10 kV/µs Minimum Common Mode Rejection (CMR) at Vcm = 600 V Creepage Distance: 7.4 mm. Clearance: 7.1 mm. Description The HCPL-T251 contains GaAsP LED. The LED is optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by this optocoupler makes it ideally suited for directly driving small or medium power IGBTs.
