Working Principle

The 1PMT5950E3/TR7 supplement with a single power connection, using a single kink resistor to maintain a constant output voltage. The basic principle of operation is that when the output voltage rises, the Zener diode reduces the current until the Zener voltage is reached where the diode transitions into a reverse-bias state. When the input current is great enough to cause the Zener diode to become forward biased, it allows the voltage to drop down until the output current is limited by the kink resistor. This process of controlling the output voltage continues as the input current increases.

The 1PMT5950E3/TR7 utilizes a small kink resistor to limit the output current in addition to the built-in Zener diode. It allows small currents to safely pass through the diode whilst limiting the current when the diode becomes forward-biased. This protected the diode from too much current and aids in maintaining a constant output voltage.

Zener diodes provide improved stability and accuracy compared to conventional methods and are used for relatively low power applications. The 1PMT5950E3/TR7 has a tight tolerance and stability, making it an ideal choice for low voltage applications such as MP3 players, digital cameras, and handheld gaming devices.

In conclusion, the 1PMT5950E3/TR7 Zener diode is the perfect choice for ultra-small, portable and low voltage applications. It offers low power consumption, low forward voltage and fast recovery. Moreover, it provides tight tolerance and excellent stability. This small, surface-mount device is an ideal choice for current high-frequency, high-speed applications.
