TPD2E009DBZR Circuit Protection

TVS - Diodes

TVS (Transient Voltage Suppressors) diodes are widely used in electronic systems to protect them from power and electrostatic stress overvoltage. The function of these TVS diodes is to provide protection from overvoltages such as those caused by lighting, switching transients, and other power surges, ultimately preventing damage to the system. The TPD2E009DBZR is such a diode with many applications and a unique working principle.

Applications of TPD2E009DBZR Transient Voltage Suppressors

The TPD2E009DZBR is a unidirectional diode, which can be used in a variety of applications. This diode is used in power systems, such as automotive power systems, as well as in industrial applications such as AC/DC power supplies, networking equipment, medical equipment, and even consumer electronics. With its wide operating temperature range from -55°C to +150°C, it can be used in multiple environments. The TPD2E009DBZR is also used for industrial safety against electrostatic discharge (ESD), as it is capable of withstanding ESD events up to contact discharge of 8 kilovolts and air discharge of 15 kilovolts.

Working Principle of TPD2E009DBZR Transient Voltage Suppressors

The working principle of the TPD2E009DBZR is based on its unidirectional feature. Its structure consists of a PN junction diode and a protection diode in series. When the reverse voltage across the diode is lower than the “valley point” of the diode, the diode will operate in avalanche mode and the voltage will increase according to the rule of the diode; when the reverse voltage exceeds the “valley point”, the diode is blocked and the overvoltage is clamped and forced to stay lower than the breakdown voltage of the diode. In this way, the voltage applied to the protected equipment will not go further than the breakdown voltage, thus protecting the device from any incoming surges or transients.

The TPD2E009DBZR has an advanced Fast Recovery Intrinsic Avalanche Diode (FRIDA) technology which provides an ultra-low switching spike for a sharp turn-off response and thus reducing the effect of overshoot voltage between positive and negative transients. The FRIDA technology also provides an extremely low on-state resistance of 0.0011 Ohms, an extremely low leakage current, and very fast activation time.

Conclusion

In conclusion, the TPD2E009DBZR is a Transient Voltage Suppressor with many applications and advanced technologies. Its unidirectional working principle provides overvoltage protection in power systems and from electrostatic discharge, protecting the devices from damage. With its unique FRIDA technologies, this diode can provide an ultra-low switching spike, low on-state resistance, and extremely low leakage current and fast activation time.
