  • Designed for Complementary Use with BD646, BD648, BD650 and BD652
  • 62.5 W at 25°C Case Temperature
  • 8 A Continuous Collector Current
  • Minimum hFE of 750 at 3 V, 3 A absolute maximum ratings at 25°C case temperature (unless otherwise noted) NOTES: 1. This value applies for t p ≤ 0.3 ms, duty cycle ≤ 10%. 2. Derate linearly to 150°C case temperature at the rate of 0.4 W/°C. 3. Derate linearly to 150°C free air temperature at the rate of 16 mW/°C. 4. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, I B(on) = 5 mA, RBE = 100 Ω, VBE(off) = 0, RS = 0.1 Ω, VCC = 20 V .

TO-220 3-pin plastic flange-mount package This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic compound. The compound w ill withstand soldering temperature with no defor mation, and circuit performance characteristics will remain stable when operated in high humidity conditions. Leads require no additional cleaning or processing when used in soldered assembly.
