Sensitive
SCRs
(0.8 A to 10 A)
E5
General Description
The Teccor line of sensitive SCR semiconductors are half-wave
unidirectional, gate-controlled rectifiers (SCR-thyristor) which
complement Teccor's line of power SCRs. This group of
packages offers ratings of 0.8 A to 10 A, and 200 V to 600 V with
gate sensitivities of 12 µA to 500 µA. For gate currents in the
10 mA to 50 mA ranges, see “SCRs” section of this catalog.
The TO-220 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.
Teccor's line of SCRs features glass-passivated junctions to
ensure long-term device reliability and parameter stability.
Teccor's glass offers a rugged, reliable barrier against junction
contamination.
Tape-and-reel packaging is available for the TO-92 package.
Consult the factory for more information.
Variations of devices covered in this data sheet are available for
custom design applications. Consult the factory for more
information.

General Notes
Teccor 2N5064 and 2N6565 Series devices conform to all JEDEC
registered data. See specifications table on pages E5 - 2 and
E5 - 3.
The case lead temperature (TC or TL) is measured as shown on
dimensional outline drawings in the “Package Dimensions” section
of this catalog.
All measurements (except IGT) are made with an external resistor
RGK = 1 k unless otherwise noted.
All measurements are made at 60 Hz with a resistive load at an
ambient temperature of +25 °C unless otherwise specified.
Operating temperature (TJ) is -65 °C to +110 °C for EC Series
devices, -65 °C to +125 °C for 2N Series devices, -40 °C to
+125 °C for “TCR” Series, and -40 °C to +110 °C for all others.
Storage temperature range (TS) is -65 °C to +150 °C for TO-92
devices, -40 °C to +150 °C for TO-202 and Compak 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.

Figure E5.17 Power Dissipation (Typical) versus RMS On-state Current
Figure E5.18 Normalized DC Latching Current versus Case Temperature
Figure E5.19 Simple Test Circuit for Gate Trigger Voltage and
Current Measurement
Note: V1 — 0 V to 10 V dc meter
VGT — 0 V to 1 V dc meter
IG — 0 mA to 1 mA dc milliammeter
R1 — 1 k potentiometer
To measure gate trigger voltage and current, raise gate voltage
(VGT) until meter reading V1 drops from 6 V to 1 V. Gate trigger
voltage is the reading on VGT just prior to V1 dropping. Gate trig-
ger current IGT can be computed from the relationship
where IG is reading (in amperes) on meter just prior to V1 drop-
ping.
Note: IGT may turn out to be a negative quantity (trigger current
flows out from gate lead). If negative current occurs, IGT value is
not a valid reading. Remove 1 k resistor and use IG as the more
correct IGT value. This will occur on 12 µA gate products.
