The device also provides a low-impedance path in order to minimize loss at high frequencies.

Application Fields

The 1PGSMA4764HM2G is largely used in precision applications with demanding electrical requirements. The device is suitable for use in applications such as voltage regulation, voltage protection, power supplies and voltage switchin. It can also be used in medical and automotive applications, due to its low noise profile and temperature compensation. The device can provide protection against over-voltage, when used in series with resistors and capacitors.

Working Principle

The 1PGSMA4764HM2G is a single Zener diode, which works by regulating the output of a power supply, while protecting components from over-voltage and over-current conditions. The diode is designed to operate at a certain breakdown voltage, which is dependent on the zener voltage. The zener voltage is determined by the zener breakdown voltage, which is in turn determined by the doping level on the n-type and p-type semiconductor material. When the forward current passes through the diode, it is partially stopped, creating a voltage drop across the diode. This voltage drop is equal to the zener voltage, thus creating a regulated output voltage.When operating in reverse-bias conditions the 1PGSMA4764HM2G operates as a voltage regulator, where the current flow is limited by the zener breakdown voltage. The Zener diode also acts as an impedance matching element, providing an impedance of 6 ohms at high frequencies. This reduces the RF noise from creeping into the circuit.

Conclusion

The 1PGSMA4764HM2G is a single Zener diode, which is designed to provide reliable and cost-effective performance in a variety of applications. The device is suitable for use in precision applications which require voltage regulation, voltage protection, power supplies and voltage switching. The device is also suitable for medical and automotive applications due to its low noise profile and temperature compensation. The 1PGSMA4764HM2G operates as a voltage regulator when operating in reverse-bias conditions, and also acts as an impedance matching element to reduce RF noise.
