Through-hole zener diodes rated at fixed breakdown (avalanche) voltages for voltage regulation and clamping. Unlike standard diodes, they conduct in reverse above the rated voltage, making them useful for shunt regulation and overvoltage protection.
E12 resistor kits, ceramic and electrolytic capacitor sets, 1N4148/1N4007 diodes, TIP120 Darlingtons, IRLZ44N MOSFETs and 100F supercapacitors — bench stock in kit quantities.
