The Teccor line of thyristor SCR semi-conductors are half-wave, unidirectional, gate-controlled rectifiers which complement Teccor's line of sensitive SCRs. Teccor offers devices with ratings 70 A and 1000 V, with gate sensitivities from to 50 mA. If gate currents in the 500 µA ranges are required, see "Sensitive SCRs" section of this catalog. Three packages are offered in electrically isolated construction where the case or tab is internally isolated to allow the use of low-cost assembly and convenient packaging techniques. The Teccor line of SCRs features glass-passivated junctions to ensure long-term reliability and parameter stability. Teccor's glass offers a rugged, reliable barrier against junction contamination. Variations of devices covered in this data sheet are available for custom design applications. Consult the factory for more information.

· All measurements are made 60 Hz with a resistive load at an ambient temperature +25 °C unless otherwise specified. Operating temperature range (TJ) +125 °C for TO-92 devices and +125 °C for all other packages. Storage temperature range (TS) +150 °C for TO-92 devices, +150 °C for TO-202 and TO-220 devices, and +125 °C for all others. Lead solder temperature is a maximum 230 °C for 10 seconds maximum; ³1/16" (1.59 mm) from case. The case temperature (TC) is measured as shown on dimensional outline drawings in the "Package Dimensions" sectionof this catalog.
See Figure E6.5 through Figure E6.16 for current rating at specified operating case temperature. See Figure E6.1 and Figure E6.2 for free air current rating. See Figure E6.19 and Figure E6.20 for instantaneous on-state current versus on-state voltage (typical). See Figure E6.18 for IGT versus TC. See Figure E6.17 for IH versus TC. For more than one full cycle rating, see Figure E6.23. See Figure E6.22 for tgt versus IGT. See Figure E6.21 for VGT versus TC. Test conditions are as follows:· 1 A for 1 A devices and 2 A for all other devices· Pulse duration = 50 µs, dv/dt = 20 V/µs, di/dt = -10 A/µs for 1 A devices, and -30 A/µs for other devices· IGT mA at turn-on (10) See Figure E6.5 through Figure E6.10 for maximum allowable case temperatures at maximum rated current.

(15) The or M package rating is intended for high surge condition use only and not recommended for ³50 A rms continuous current use since narrow pin lead temperature can exceed PCB solder melting temperature. Teccor's J package or W package is recommended for ³50 A rms continuous current requirements.
