SENSITIVE GATE SILICON
CONTROLLED RECTIFIERS
REVERSE BLOCKING
THYRISTORS
DESCRIPTION
PNPN devices designed for high volume,
line-powered consumer applications such as relay
and lamp drivers, small motor controls, gate drivers
for larger thyristors, and sensing and detection
circuits. Supplied in an inexpensive plastic TO-92
package which is readily adaptable for use in
automatic insertion equipment.
DESCRIPTION

and Other Logic circuits
*Blocking Voltage to 600V
*On-State Current Rating of 0.8A RMS at 80°C
*High Surge Current Capability – 10A
*Minimum and Maximum Values of IGT, VGT and IH
Specified for Ease of Design
*Immunity to dV/dt – 20V/µsec Minimum at 110°C
*Glass-Passivated Surface for Reliability and
Uniformity

Note: VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate
voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the anode.
Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the
devices are exceeded.
