Test Conditions:
ET Product: E-T product rating is for the secondary (gate) windings and is based upon a peak flux denisty of 2200 Gauss at 25°C when used in a bipolar-driven application.
Primary Inductance (min): Tested at 10 kHz, 0.1Vrms.

• Electrical specifications at 25°C.
• Operating range: -40°C to +130°C.
• Meets UL94V-0.
