Vintage RCA 2N689 Power-Control and Power-Switching Thyristor NOS

Description

A vintage RCA 2N689 Power-Control and Power-Switching Thyristor NOS in original packaging with mounting kit.  Four available.
RCA 2N681 through 2N690 controlled-rectifiers are all-diffused, three-junction, silicon devices for use
in power-control and power-switching applications requiring blocking-voltage capabilities to 600 volts and forward-current capability of 16 amperes (average value) or 25 amperes (rms value).
FEATURES
• Low forward voltage drop at high current levels
• All-diffused construction - assures exceptional uniformity and stability of characteristics
• Law thermal resistance
• Multi-diffusian process - permits precise control of individual junction parameters
• Exceptionally high stud-torque capability through use of high-strength copper-alloy stud
• Symmetrical gate-cathode construction - provides uniform current density. rapid electrical conduction, and efficient heat dissipation
• Direct-soldered internal construction - assures exceptional resistance to fatigue
• Each unit aged at maximum ratings to assure dependable performance
• Shorted emitter gate-cathode construction
• Low leakage currents, both forward and reverse
