1N5257B-TP

1N5257B-TP is a common Zener Diode, designed specifically for voltage-stabilizing applications. A Zener Diode is constructed from a single piece of semiconductor material, with a PN junction. The PN junction allows voltage to be conducted in one direction, while preventing or restricting current conduction in the opposite direction. As the voltage comes close to or exceeds the breakdown voltage, the PN junction conducts current and the Zener Diode enters the Zener breakdown region. As the PN junction is subject to a large voltage, a much higher current than usual is allowed to flow.

The 1N5257B-TP Diode has a breakdown voltage of 5.1V and a peak power rating of 500mW. It can handle currents up to 100mA and has an forward voltage of 0.65V at 100mA. Its reverse leakage current is typically 8nA at 5.1V with a reverse recovery time of 5ns. The maximum operating temperature is up to 125 degree Celsius. The diode comes in the TO-92 package, with a weight of 0.2 g.

The 1N5257B-TP Diode is suitable for applications including voltage-regulated power supplies, voltage-controlled oscillators, voltage clamping, noise suppression, waveform generators and any other applications requiring a consistent voltage output. The diode can be used to limit the voltage output of an AC power source to a consistent, safe 5.1V level.

The working principle of the 1N5257B-TP Diode is simple and effective. When a voltage is applied across the diode, the depletion layer between the PN junction expands, increasing resistance and preventing current flow. Once the applied voltage is greater than the breakdown voltage of the diode, the PN junction allows current to flow, entering the Zener breakdown region. In this region, the voltage across the diode becomes almost a constant, allowing for an even and consistent output.

The 1N5257B-TP diode is a versatile, cost-effective solution for voltage regulation and other applications requiring a reliable source of constant voltage. With its low forward voltage of 0.65V at 100mA, it can provide a consistent and reliable 5.1V output. It is well-suited for applications requiring a precise voltage output in a wide range of environmental conditions.
