- Non inverting Optocoupler #HPCL3120 #HCNW3120 can be use to isolated two different circuits digital signals
the isolation level is upto 5000 volt or 5kv between inputs and outputs channel.
this is very good IGBT or Mosfets gate driver it can give the 2.5 amp max gate drive current
The HCPL-3120 contains a GaAsP LED while the HCPL-
J312 and the HCNW3120 contain an AlGaAs LED. The LED
is optically coupled to an integrated circuit with a power
output stage. These optocouplers are 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 these optocouplers make them ideally
suited for directly driving IGBTs with ratings up to 1200
V/100 A. For IGBTs with higher ratings, the HCPL-3120
series can be used to drive a discrete power stage which
drives the IGBT gate. The HCNW3120 has the highest in-
sulation voltage of VIORM=1414Vpeak in the IEC/EN/DIN
EN 60747-5-5. The HCPL-J312 has an insulation voltage
of VIORM=1230Vpeak and the VIORM=630Vpeak is also
available with the HCPL-3120
Features
• 2.5 A maximum peak output current

Broadcom gate drivers are very good nice lecture on optocoupler ic
👏
What about led voltage value ?
Koi same 3A ki ic he kya name bataye
Application kya hai apka
