1PMT5955E3/TR13

Diodes - Zener - Single

The 1PMT5955E3/TR13 diode is a single Zener diode from the Vishay Semiconductor’s general purpose family. This diode typically consists of a single N-type and P-type semiconductor junction, enabling the diode to conduct in two directions.

Application Field

The 1PMT5955E3/TR13 diode is a commonly used component in consumer electronics and other devices. It can be used to protect circuits against voltage transients, power spikes, and over-voltage conditions, as well as to provide a stable voltage and current reference across the circuit. It can also be used to improve the efficiency of power supplies by providing a constant current over a wide range of input voltages.

Working Principle

The Zener diode operates by allowing a reverse current to flow during high voltages, offering protection to a circuit. This protective action is achieved through a phenomenon called avalanche breakdown. In this process, when the reverse voltage reaches a certain level, electrons and holes are multiplied in the depletion region, leading to a surge in the current. The Zener diode gives a stable voltage, anywhere from 0.2 to 50 volts, depending on the type.

The forward voltage drop across a standard diode is typically around 0.6 Volts, while the 1PMT5955E3/TR13 is a low-power Zener diode and features a voltage regulation of 5.7V. This lower voltage drop allows for greater efficiency in the transfer of power through the circuit.

Design Variations

The Vishay Semiconductor 1PMT5955E3/TR13 diode is a single Zener diode, featuring a maximum rated power of 375 mW, 6A peak forward current, and a typical maximum reverse current of 2 μA. It also has a thermal resistance of 95 °C/W and an operating temperature range between -40 and +155 °C. The diode is housed in a SOT23-3 package and is offered in both through-hole and surface-mount packages.

Conclusion

The 1PMT5955E3/TR13 diode is a single Zener diode offering a voltage regulation of 5.7V and low thermal resistance, making it ideal for applications that require protection against power surges and over-voltage conditions. With its low voltage drop and ability to conduct in two directions, it can be used to regulate voltage and current in a wide range of devices, from consumer electronics to industrial applications.
