All Avago 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, that 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.

ACNW3410
Data Sheet
Application Information
Application Information
Product Overview Description
The ACNW3410 is an optically isolated power output stage capable of driving IGBT or power MOSFET. Based on BCDMOS
technology, this gate drive optocoupler delivers higher peak output current, better rail-to-rail output voltage performance and
faster speed than the previous generation products.
The high peak output current and short propagation delay are needed for fast IGBT switching to reduce dead time and improve
system overall efficiency. Rail-to-rail output voltage ensures that the MOSFET’s gate voltage is driven to the optimum intended
level with no power loss across the MOSFET. This helps the designer lower the system power which is suitable for bootstrap power
supply operation.
The ACNW3410 has a VE pin that allows of use negative power supply without affecting the UVLO monitoring the positive power
supply. It has very high CMR (common mode rejection) rating which allows the microcontroller and the MOSFET to operate at very
large common mode noise found in industrial motor drives and other power switching applications. The input is driven by direct
LED current and has a hysteresis that prevents output oscillation if insufficient LED driving current is applied. This eliminates the
need of additional Schmitt trigger circuit at the input LED.
Recommended Application Circuit
The recommended application circuit shown in the following figure illustrates a typical gate drive implementation using the
ACNW3410.
The supply bypass capacitors provide the large transient currents necessary during a switching transition. Because of the transient
nature of the charging currents, a low current (5.0 mA) power supply will be enough to power the device. The split resistors (in the
ratio of 1:1) across the LED will provide a high CMR response by providing a balanced resistance network across the LED. Connect
pin 1 and pin 4 to LED common.
The gate resistor RG serves to limit gate charge current and controls the IGBT switching times.
In PC board design, care should be taken to avoid routing the IGBT’s collector or emitter traces close to the ACNW3410 input as this
can result in unwanted coupling of transient signals into ACNW3410 and degrade performance.

Ambient Temperature: Junction to Ambient Thermal Resistances were measured approximately 1.25 cm above the optocoupler at
~23°C in still air.

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) per JEDEC standards. The temperature at the LED and Detector junctions of the optocoupler can be calculated
using the following equations.
T1 = (R11 * P1 + R12 * P2) + TA -- (1)
T2 = (R21 * P1 + R22 * P2) + TA -- (2)
