ACPL-H312 and ACPL-K312
2.5 Amp Output Current IGBT Gate Drive Optocoupler
with Low ICC and UVLO in Stretched SO8
Data Sheet
Description
Features
The ACPL-H312/K312 contains a GaAsP 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
1200V/100A. For IGBTs with higher ratings, the
ACPL-H312/K312 series can be used to drive a discrete power
stage which drives the IGBT gate. The ACPL-H312 has an
insulation voltage of VIORM = 891 Vpeak (Option 060). The
ACPL-K312 has an issulation voltage of VIORM = 1140 Vpeak
(Option 060).

All Broadcom data sheets report the creepage and clearance inherent to the optocoupler component itself. These
dimensions are needed as a starting point for the equipment designer when determining the circuit insulation
requirements. However, once mounted on a printed circuit board, minimum creepage and clearance requirements
must be met as specified for individual equipment standards. For creepage, the shortest distance path along the
surface of a printed circuit board between the solder fillets of the input and output leads must be considered (the
recommended land pattern does not necessarily meet the minimum creepage of the device). There are
recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve
desired creepage and clearances. Creepage and clearance distances will also change depending on factors such as
pollution degree and insulation level.

Thermal Model for ACPL-H312/K312
Stretched-SO8 Package Optocoupler
Description
This thermal model assumes that an 8-pin single-channel
plastic package optocoupler is soldered into a 7.62 cm ×
7.62 cm printed circuit board (PCB). The temperature at the LED
and Detector junctions of the optocoupler can be calculated
using the equations below.
Definitions:

Data Sheet
Quick Gate Drive Design Example Using
ACPL-H312/K312
The total power dissipation (PT) is equal to the sum of the LED
input-side power (PI) and detector output-side power (PO)
dissipation:
PT = PI + PO
Using the given thermal resistances and thermal model
formula in this data sheet, we can calculate the junction
temperature for both LED and the output detector. Both
junction temperatures should be within the absolute
maximum rating. For this application example, we set the
ambient temperature as 78°C and use the high conductivity
thermal resistances.
LED junction temperature,
PI = IF(ON) ,max × VF,max
T1
where,
= (311 × 28.8 + 111 × 124.2) + 78
IF(ON),max = 16 mA (Recommended Operating Conditions)
= 22.7 + 78 = 100.7°C
VF,max = 1.8V (Electrical Specifications (DC))
PO = PO(BIAS) + PO(SWTICH) = ICC2 × (VCC2 – VEE ) + VGE × QG
× fSWITCH
where,
Output IC junction temperature,
T2
PO(SWITCH) = Power dissipation in the driver due to charging
and discharging of power device gate capacitances.
ICC2 = Supply Current to power internal circuity = 3.0 mA
(Electrical Specifications (DC))
= 24 + 78 = 102°C
TIn this example, both temperature are within the maximum
125°C. If the junction temperature is higher than the maximum
junction temperature rating, the desired specification must be
derated accordingly.
VGE = VCC2 + |VEE| = 18 – (–5V) = 23V (Application example)
QG = Total gate charge of the IGBT or MOSFET as described in
the manufacturer specifi cation = 24 0nC (approximation of
100A IGBT which can be obtained from IGBT data sheet)
fSWITCH = switching frequency of application = 10 kHz
Similarly using the maximum supply current ICC2 = 3.0 mA.
= 16 mA × 1.8V = 28.8 mW
PO
= PO(BIAS) + PO(SWITCH)
= (R21 × P1 + R22 × P2) + TA
= (111 × 28.8 + 168 × 124.2) + 78
PO(BIAS) = Steady-state power dissipation in the driver due to
biasing the device.
PI
= (R11 × P1 + R12 × P2) + TA
= 3.0 mA × (18 V – (–5 V)) + (18V + 5V) × 240nC × 10 kHz
= 69 mW + 55.2 mW
= 124.2 mW
