2N1539 Overview
CASE 11 (TO-3) CASE 4-04 (TO-41) MAXIMUM RATINGS For units with solder lugs attached, specify devices MP1539, A etc. or frequencies below !10( 25 cps the transistor must be operated ~ 80 within the constant Pn = Vc x Ie ~ 60 hyperbolic curve. This curve has a ~ 40 value of 106 Watts at case ternpera- tures of 250 C and is a Watts at 1100 C ~ ~ 20 0 with a linear relation between the two ....
