EC103D Silicon-controlled rectifier (400 V, 0.8 A) This is the output stage used in most of our kits. The SCR serves as an electronic switch. EC103D - $0.75
TYN408 Silicon-controlled rectifier, high current (400 V, 8 A) This SCR can be used in place of the previous one for higher current applications. TYN408 - $0.75
2N2222 NPN transistor This transistor is used in our sound triggers and transistor photogates. 2N2222 - $0.35
For PC sockets for the chips below, see PCB Parts.
555 Single timer The 555 timer is used in our photogates. 555 - $0.50
556 Dual timer The 556 timer is used in our delay units. 556 - $0.75
LM386 amplifier The LM386 amplifier is used in our SK3 Sound Triggers. LM386 - $1.20
PS2501 Optocoupler with transistor output This PS2501 optocoupler is used in our Camera Opto-Switches. It has a non.93-latching, transistor output that can be triggered repeatedly without need of being reset. This optocoupler can also be used with flash units having low-voltage terminals (<80 V). PS2501 - $0.60
MOC3021 Optocoupler with triac output This optocoupler can be used in place of an SCR to trigger a flash unit or a camera shutter. When used to trigger a camera shutter, the camera circuit may need to be reset after each firing since the optocoupler has a latching output. This is not an issue for most flash units. Flash units with voltages as high as 400 V across the terminals can be used. MOC3021 - $0.93
