HCPL-3020/HCPL-0302

0.4 Amp Output Current IGBT Gate Drive Optocoupler

Description

The HCPL-3020 and HCPL-0302 consist of a GaAsP LED 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 this optocoupler makes it ideally suited for directly driving small or medium power IGBTs. For IGBTs with higher ratings, the HCPL-0314/3140 (0.6 A), HCPL-3150 (0.6 A) or HCPL-3120 (2.5 A) gate drive opto-couplers can be used.

Notes:

1. Derate linearly above 70°C free air temperature at a rate of 0.3 mA/°C.

2. Maximum pulse width = 10 µs, maximum duty cycle = 0.2%. This value is intended to allow for component tolerances for designs with IO peak minimum = 0.2 A. See Application section for additional details on limiting IOL peak.

3. Derate linearly above 85°C, free air temperature at the rate of 4.0 mW/°C.

4. Input power dissipation does not require derating.
