Replacement of 1N4728A 3.3 zener diode Use a series of 2.7V Zener with a normal rectifier diode (2.7+[0.6-0.7]=3.3-3.4V) Use 5 regular diodes in series. Voltage drop across each diode is .7 volts x5 = 3.5volts Use the 5.1 and take the output via 3 diodes forward biased. 0.6 volt drop per diode, you can slash … Read more
DESCRIPTION INFORMATION These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external … Read more
Bridge Rectifier IC Pin out A bridge rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. AC = Alternating current (INPUT) DC+ = Positive direct current (OUTPUT) DC- = Negative direct current (OUTPUT)
