The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Although 5V-powered logic isstill common in many applications,most FPGAs support interfacelevels of 3.3V and lower. When youconnect an FPGA to higher voltagelevels, the FPGA’s application ...

[Kevin] doesn’t stock zener diodes anymore. Why? Because for everything he used to use zeners, he now uses TL431 bandgap voltage references. These look like zener diodes but have an extra terminal.

Toshiba has created a range of automotive-grade Zeners for surge protection in the 0.8 x 1.6mm SOD-523 package. Called the XCEZ series, they rated at 150 or 300mW (see below) and come in 20 E24 values ...

Before there were bandgaps, voltage references ranged from neon glow tubes to Zener diodes. Paul Rako, with the help of Bob Pease and others, “drifts” back in time to trace their history. Back on ...
