Diodes are a form of electrical component which are used in all manner of applications and machines. These allow for electrical current to be conducted in one direction and then reversed, depending on the voltage and current being passed through them. Zener diodes, in particular, have the ability to limit current and regulate voltage, and can be specified for different operating requirements. One such device is the 1N5956P/TR12. As a type of Zener single-diode, this component has a specific application field and working principle that should be familiarized with when specifying for a project.

1N5956P/TR12 Zener single-diodes are built for handling relatively low current applications. Specifically, these devices are fit for low voltage direct current (DC) use and offer precise regulation with a low maximum reverse leakage current. This makes them ideal for components such as regulators, temperature protection, voltage surges, and reverse bias protection. The regulating voltage of this component is 12V, with an allowable tollerance of -25%, +5%. Its maximum forward current is 2A, with a reverse breakdown current of 5mA.

As a Zener diode, the 1N5956P/TR12 uses reverse conduction in order to regulate voltage. This entails leveraging the voltage differential between two ends of the diode. When the reverse voltage is less than the avalanche voltage (VZ) of the diode, then no current passes through it. As soon as the reverse voltage is higher than this, the diode begins to conduct in the reverse direction. This allows for a fixed and constant voltage at the diode’s output, the voltage being determined by the Zener design.

In this case, the 1N5956P/TR12 component operates with a peak reverse power dissipation of 500mW and a peak forward power dissipation of 1.32W. It has a thermal resistance between junction and element of 200°C/W, as well as a thermal resistance between pad and element of 250°C/W. For terms of its operation, it works at a storage temperature of -50° to 150°, and with an operating temperature of -40° to 85°.

As far as physical characteristics are concerned, the 1N5956P/TR12 is built as a single-crown device. It measures 2.2mm x 5.2mm and has a minimum isolating voltage of 2500V. Its junction temperature maximum is 75° and its mounting capacity is SMT. Its electrical life expectancy is 800 hours.

All in all, the 1N5956P/TR12 Zener single-diode device is an efficient component for regulating low voltage direct current. It offers efficient reverse conduction and current limitation, allowing it to be specialized and tailored to fit a wide array of applications. As such, it is an ideal electrical element for low-power projects, particularly those with specific current and voltage demands.
