2M47ZHB0G Application Field and Working PrincipleApplication Field2M47ZHB0G is a highly reliable and stable Zener diode mainly suitable for applications where voltage stabilization is critical, such as voltage regulator, voltage reference circuit, industrial and medical instrumentation and equipment, etc.Working Principle2M47ZHB0G is a low current type Zener diode which is designed to minimize noise and provide stabilization voltage. It is silicon PN junction diode with an integrated series of high resistive words formed inside its active area. It operates in forward conduction and Zener breakdown regions.In the forward conduction region, the diode operates as a normal PN junction for positive voltages applied on its anode relative to its cathode. The current decreases steadily in the forward biased condition. In comparison, the Zener diode starts to become conducting as its voltage reaches its minimum breakdown voltage. At that point, the current across the device increases rapidly due to internal avalanche breakdown.In the reverse breakdown region, the device can tolerate higher voltages than in the forward conduction region, depending on its specifications. The reverse breakdown voltage range is wide, ranging from 5V up to 200V.The device is designed to provide the exact Zener voltage drop and it will be the same at all temperatures. This voltage is extremely low and does not vary noticeably with an increase or decrease in current. The device will also auto-adjust its Zener voltage as per changes in temperature.The 2M47ZHB0G is designed to perform consistently and provide high reliability, even in highly hostile environments. Its maximum power dissipation is 1 Watt. The device has high insulation resistance, large surge current capability, high stability and comprises of low noise properties. It has a very low thermal resistance coefficient which allows it to be exposed to maximum power dissipation over a larger area. The device also comes with high speed turn-on characteristics and thermal coverage.Conclusion2M47ZHB0G is a Zener diode designed to provide superior voltage stabilization in industrial and medical instrumentation and other critical applications. It has a wide range of reverse breakdown voltage, low voltage drop, high speed turn-on characteristics and high stability. Its low power dissipation capabilities and superior thermal properties make it an ideal choice for a variety of applications.
