IG min =

VGT

R111 + 14 mA =

220 + 8 mA = 12.5 mA

Considering this current value and the VCC_AC minimum voltage, the gate resistor calculation is:

R103 + R104 =

V R103 + R104

IG min

VCC_AC min + VGT max − VCEsat

IG min

= 13 + 1 − 0.3

12.5 × 10−3

= 1096 Ω

The nearest normalized values are 560 Ω.
You can calculate maximum power in the resistors considering the VCC_AC maximum voltage:

IG max =

V R103 + R104

R103 + R104 =

VCC_AC min + VGT max − VCEsat

R103 + R104

= 21 + 1 − 0.3

1120

= 19 mA

PR103 = R103 × IG max

= 0.21 W

Therefore, R103 and R104 are 560 Ω/0.5 W resistors.

Note:

Use the above formulas to recalculate resistor values in case of schematic use in another design with a different
ambient temperature.
