BZD27C130PHRUG

Diodes - Zener - Single

The BZD27C130PHRUG is a single zener diode certified according to the AEC-Q101 standard for automotive applications. It is housed in a PowerDI123 surface-mount plastic housing and features a lead-free plated flame-retardant package.

Application Field

The BZD27C130PHRUG is primarily used in applications such as over-voltage protection circuits, voltage regulator circuits and temperature compensation circuits. It can also be used as a clamping diode in power supplies or DC power converters. The device is also suitable for applications that require low noise, low leakage current and low capacitance.

Working Principle

The BZD27C130PHRUG is a voltage-tunable device based on the principle of Avalanche Breakdown. When an avalanche voltage is applied to a reverse-biased PN junction, it spontaneously breaks down and the junction current increases rapidly. Consequently, the voltage across the PN junction decreases and the device is said to be in a zener state. The zener voltage and the knee voltage of the device are different, ensuring increased protection from over-voltage situations. The BZD27C130PHRUG also features temperature-dependent characteristics, making it suitable for temperature-compensated applications.

Parameters

The BZD27C130PHRUG offers a zener voltage range of 13V to 27V with a maximum leakage current of 20uA. Its power rating is 150mW and its maximum repetitive reverse voltage is 40V. The typical junction capacitance of the device is 7.5pF, which enables it to be used in low-noise applications.
