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.

Example:
HCPL-T251 #XXXX
No Option = Standard DIP Package, 50 per tube.
300 = Gull Wing Surface Mount Option,
50 per tube.
500 = Tape and Reel Packaging Option,
1000 per reel.
XXXE = Lead Free Option.
Remarks: The notation “#” is used for existing products, while (new)
products launched since 15th July 2001 and lead free option will use “-”
A 0.1 µF bypass capacitor must be connected between pins 5 and 8.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component
to prevent damage and/or degradation which may be induced by ESD.

Notes:
4. The difference between tPHL 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).
