450-V Silicon N-P-N Types
For Off-Line Switching-Regulator Type Power-Supply Applications
Features:
• High·voltage ratings for operation from power lines without a step-down transformer
" Popular JEDEC TO·3 and TO·66 hermetic packages
Applications:
g For use in switching-regulator supplies which feature: - A substantial reduction in size and weight due to elimination of the 60·Hz power transformer.
- Operation with a substantial reduction of heat
RCA 40850-40854, inclusive, are silicon n·p·n power transistors,selected from RCA's line of silicon power transistors,for power·supply applications. Their high·voltage ratings (450 V) permit operation directly off the power line thereby eliminating the heavy and bulky 60-Hz power transformer.
Their fast switching speeds (.
