yy < le a TO - 92 sale ai THERMOTAB Pil TO-220AB tk TO-202AB A oi K G Sensitive SCRs (0.8 — 10 Amps) General Description The Teccor Electronics, Inc. line of sensitive SCR semiconduc- Tape-and-reel packaging is available for the TO-92 package. tors are half-wave unidirectional gate-controlled rectifiers (SCR- Please consult factory for more information. thyristor) which complement Teccor's line of power SCRs. This Variations of devices covered in this data sheet are available for group of packages offers ratings of 0.8-10 amps, and 50-600 custom design applications. Please consult the factory for more volts with gate sensitivities of 12-500 microamps. If gate currents information in the 10-50 milliamp ranges are required, please consult Tec- . cor's non-sensitive SCR technical data sheets. Electrically Isolated Packages This group of Teccor sensitive SCRs is available in a choice of three different product packages. The TO-220AB and TO-92 are electrically isolated where the case or tab is internally isolated to allow the use of low cost assembly and convenient packaging techniques. Features + Electrically-isolated To-220AB package Glass Passivation + High Voltage Capability up to 600 Volts Teccor's line of SCRs features glass-passivated junctions to + High Surge Capability — up to 100 Amps ensure long term device reliability and parameter stability. Tec- + Glass Chip Passivation cor's glass offers a rugged, reliable barrier against junction con- tamination. Teccor Electronics, Inc. 54 Sensitive SCRs (972) 580-7777
