• Customer-Specified Selections Available SOT-93 PACKAGE (TOP VIEW) Pin 2 is in electrical contact with the mounting base. MDTRAA B C E absolute maximum ratings at 25°C case temperature (unless otherwise noted) NOTES: 1. This value applies for tp ≤ 0.3 ms, duty cycle ≤ 10%. 2. Derate linearly to 150°C case temperature at the rate of 0.92 W/°C. 3. Derate linearly to 150°C free air temperature at the rate of 28 mW/°C. 4. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, IB(on) = -0.4 A, R BE = 100 Ω, VBE(off) = 0, R S = 0.1 Ω, VC C = -20 V.
