These devices are intended for a wide variety of . switching and amplifier applications such as series and shunt cg = c regulators, and driver and output stages of high-fidelity (FLANGE) C O a amplifiers. The 8D244-series power transistors are complements of the devices in the BD243 series. (The BD243-series devices tor view 6 are described in File No. 673.) e2cs-se000 All types utilize the JEDEC TO-220AB (VERSAWATT) plas- JEDEC TO-220AB tic package.
