• Medical Equipment

Working Principle

1PMT5951A/TR7 works through electrical conduction to provide a constant voltage drop that can be used to regulate the voltage across a circuit or to provide a reference voltage for a current source. The diode is connected to a load in series, with the anode to the load terminal and the cathode to the voltage source, as it is powered. The voltage drop across the diode is determined by its internal breakdown voltage, which is typically in the range of 6-200V.

When the voltage across the diode exceeds its breakdown voltage, it turns on and a current starts to flow through the diode, reducing the voltage across the load. This process will continue until the current reaches the maximum amount of current that the diode can handle, at which point the voltage drop is regulated and held steady until the current reduces. This “clamping” effect is the key of Zenner Diode\'s operation.

The current that passes through the Zenner Diode is limited to a maximum experience rating, so if this is exceeded, the diode will be damaged. The regular reverse current is neglected, since it is too small compared to the maximum current.

Conclusion

1PMT5951A/TR7 is a single-die Zenner diode designed for various applications that require high voltage rating, low power consumption and small package size. It operates with a breakdown voltage of up to 175V, a low reverse leakage current, and a maximum current experience rating. The integrated LED indicator allows visual indication of its operating state.
