Silicon Controlled Rectifiers

Reverse Blocking Triode Thyristors

. . . PNPN devices designed for high volume, low cost consumer applications such as temperature, light and speed control; process and remote control; and warning systems where reliability of operation is critical.

•Small Size

•Passivated Die Surface for Reliability and Uniformity

•Low Level Triggering and Holding Characteristics

•Recommend Electrical Replacement for C106

•Available in Two Package Styles:

Surface Mount Leadforms Ð Case 369A

Miniature Plastic Package Ð Straight Leads Ð Case 369

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.

Preferred devices are Motorola recommended choices for future use and best overall value.
