PHP GERMANIUM AUL*?Y

JUNCTION POWER TRANSISTORS

fhesein^rjneucali) se<iieu germanium vnr power transistors are designed for use in servolaniplifiers, power converters, relay drives, voltage regulators, switching applica- tions, etc. They are capable of dissipating 10 watts at a case temperature of 71°C and currents of 3 amp. Dynamic testing of electrical parameters assures conformance to users' requirements.

Welded construction of the TO 10 case and true hermetic seal of glass-to-metal terminal [leader provides assurance of performance in environmental extremes. Widely spaced terminal'lugs are plated to facilitate lead attachment in production and are securely anchored to'prevent possible damage in use. All heat sink surfaces, are plated to avoid corrosion, which would otherwise introduce electrical or thermal discontinuities.
