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.

*All typical values at TA = 25C and VCC - VEE = 30 V, unless otherwise noted. Notes: 4. The difference between t PHL and tPLH between any two HCPL-3140 parts under the same test condition. 5. Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse, VCM, to assure that the output will remain in the high state (i.e., VO > 15.0 V). 6. Common mode transient immunity in a low state is the maximum tolerable dVCM /dt of the common mode pulse, VCM, to assure that the output will remain in a low state (i.e., VO < 1.0 V).
