Note: V1 — 0 V to 10 V dc meter VGT — 0 V to 1 V dc meter IG — 0 mA to 1 mA dc milliammeter R1 — 1 k potentiometer To measure gate trigger voltage and current, raise gate voltage (VGT) until meter reading V1 drops from 6 V to 1 V. Gate trigger voltage is the reading on VGT just prior to V1 dropping. Gate trigger current IGT Can be computed from the relationship **==> picture [78 x 24] intentionally omitted <==** where IG is reading (in amperes) on meter just prior to V1 dropping Note: Icurrent flows out from gate lead). If negative current GT may turn out to be a negative quantity (trigger occurs, IGT value is not a valid reading. Remove 1 k resistor and use IG as the more correct IGT value. This will occur on 12 µA gate products. © 2014 Littelfuse, Inc. Specifications are subject to change without notice.

Good design practice should limit the maximum continuous current through the main terminals to 75% of the device rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage. **==> picture [243 x 150] intentionally omitted <==** **----- Start of picture text -----**
