MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Silicon Controlled Rectifiers
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 TO-226AA (TO-92)
package which is readily adaptable for use in automatic insertion equipment.
Sensitive Gate Trigger Current — 200 µA Maximum
Low Reverse and Forward Blocking Current — 100 µA Maximum, TC = 125°C
Low Holding Current — 5 mA Maximum
Glass-Passivated Surface for Reliability and Uniformity

1. 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.
