General Description
The Teccor line of thyristor SCR semi-conductors are half-wave,
unidirectional, gate-controlled rectifiers which complement Tec-
cor's line of sensitive SCRs. Teccor offers devices with ratings of
1 A to 70 A and 200 V to 1000 V, with gate sensitivities from
10 mA to 50 mA. If gate currents in the 12 µA to 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 contamina-
tion.
Variations of devices covered in this data sheet are available for
custom design applications. Consult the factory for more informa-
tion.

General Notes
• All measurements are made at 60 Hz with a resistive load at an
ambient temperature of +25 °C unless otherwise specified.
• Operating temperature range (TJ) is -65 °C to +125 °C for TO-92
devices and -40 °C to +125 °C for all other packages.
• Storage temperature range (TS) is -65 °C to +150 °C for TO-92
devices, -40 °C to +150 °C for TO-202 and TO-220 devices, and
-40 °C to +125 °C for all others.
• Lead solder temperature is a maximum of 230 °C for 10 seconds
maximum; ≥1/16" (1.59 mm) from case.
• The case temperature (TC) is measured as shown on dimensional
outline drawings in the “Package Dimensions” sectionof this
catalog.

Electrical Specification Notes
(1) See Figure E6.5 through Figure E6.16 for current rating at
specified operating case temperature.
(2) See Figure E6.1 and Figure E6.2 for free air current rating.
(3) See Figure E6.19 and Figure E6.20 for instantaneous on-state
current versus on-state voltage (typical).
(4) See Figure E6.18 for IGT versus TC.
(5) See Figure E6.17 for IH versus TC.
(6) For more than one full cycle rating, see Figure E6.23.
(7) See Figure E6.22 for tgt versus IGT.
(8) See Figure E6.21 for VGT versus TC.
(9) Test conditions are as follows:
•I
T = 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
•I
GT = 200 mA at turn-on
(10) See Figure E6.5 through Figure E6.10 for maximum allowable
case temperatures at maximum rated current.
(11) See package outlines for lead form configuration. When ordering
special lead forming, add type number as suffix to part number.
(12) Pulse width ≤10 µs
(13) Initial on-state current = 200 mA dc for 1 A through 16 A devices;
400 mA dc for 20 A through 70 A devices.
(14) TC = TJ for test conditions in off state.
(15) The R, K, or M package rating is intended for high surge condition
use only and not recommended for ≥50 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 ≥50 A rms continuous current requirements.
(16) For various durations of an exponentially decaying current
waveform, see Figure E6.3 and Figure E6.4. (tW is defined as
5 time constants.)
(17) Minimum non-trigger VGT at 125 °C is 0.2 V.
