BZD27C10PHMHG

The BZD27C10PHMHG is a single Zener diode developed by NXP and is designed for use in a range of industrial, communications and multimedia applications and is applicable for voltage-regulated power.

At power distributions, the BZD27C10PHMHG rectifies the alternated current (AC) to direct current (DC). It comprises of a layer of p-doped semiconductor material which is then attached to the anode and cathode, the terminals which allow current flow.

The BZD27C10PHMHG functions as a protective device against electrical overloading, owing to it being often connected directly to the power source without additional components. Its rectifying effect also reduces the alternating current to a constant voltage.

In its functioning, the rectification process begins when electricity enters through the anode and is absorbed by the semiconductor material. When no electrical current flows, the diode acts like an insulator, prohibiting any current flow. When a higher voltage than the nominal breakdown voltage is applied to the BZD27C10PHMHG, current begins to flow. This current flow allows for the diode to change its polarity, rectifying the alternated current.

The BZD27C10PHMHG has a maximum reverse current of 40 μA at 18 volt Vz and forward current of 155 μA at 150 μA. The power dissipation is 175 mW. The device operates from an ambient temperature range from -65 °C to +300 °C. It operates at a power surge of 505 mW for a 5 μs pulse, with a reverse-recovery time of 1.5 ns. It also features a power surge of 1.18W with a 5 μs pulse. The operating temperature range is -65 °C to +200 °C and the maximum peak wavelength at a voltage of 10V is 635 nm.

The BZD27C10PHMHG features a built-in zener protection of 18 V which helps protect circuits against overvoltage. The diode also offers protection against reflected waves that occur when the load rapidly turns off, due to its quick recovery time. This feature is beneficial in preventing the appearance of radio-frequency interference.

In terms of applications, the BZD27C10PHMHG is suitable for a variety of telecommunications and digital appliance applications, including acoustic precuts, multilayer boards, PC motherboard and switching power supplies. The device is also ideal for DVR, digital TV and other devices that require surge protection, owing to its advanced surge protection capability.

In summary, the BZD27C10PHMHG is a single Zener diode designed for protection against electrical overloading and current rectification. The device features a reverse current of 40 μA, a forward current of 155 μA and a maximum peak voltage at 10 V. It is suitable for a range of telecommunications and digital appliance applications and offers advanced surge protection.
