Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the ACPL-P314/W314 has a
very low maximum V
R
to the IGBT gate and emitter (possibly by mounting the
ACPL-P314/W314 on a small PC board directly above the
IGBT) can eliminate the need for negative IGBT gate drive
in many applications as shown in Figure 19. Care should
be taken with such a PC board design to avoid routing
the IGBT collector or emitter traces close to the ACPL-
P314/W314 input as this can result in unwanted coupling
of transient signals into the input of ACPL-P314/W314
and degrade performance. (If the IGBT drain must be
routed near the ACPL-P314/W314 input, then the LED
should be reverse biased when in the off state, to prevent
the transient signals coupled from the IGBT drain from
turning on the ACPL-P314/W314.
Selecting the Gate Resistor (Rg)
Step 1: Calculate R
cation. The IGBT and R

Step 2: Check the ACPL-P314/W314 power dissipation
and increase R
