TVS - Diodes

P2SMA150A-E3/5AT is a TVS (Transient Voltage Suppression) diode designed to protect sensitive electronic systems against damage caused by voltage fluctuations. This member of the P2SMA diode family provides excellent pulse current handling capability up to 150 Amps, with a peak clamping voltage of 122.5 V.

Application field

TVS Diodes are typically used in a variety of applications: Automotive electronics, DC/DC converters, Telecommunications, UPS and other power electronics. TVS diodes are an important component used to protect circuits from voltage transients. Such transients occur in vulnerable electrical equipment when there is an unexpected sudden surge of current coursing through it, often caused by power outages and lightning strikes.

The P2SMA150A-E3/5AT is a suitable diode to be used in automotive applications, telecom systems, and other general electronics applications. For instance, the TVS diode can provide power supply protection for power supply circuits and protect electrical components from transient voltage spikes.

Working Principle

The TVS Diode is a voltage-dependent semiconductor element that operates by creating a potential barrier when a certain voltage is applied to its Cathode (C) and Anode (A) terminals. The device limits the peak voltage across its terminals and provides a specified current path. When the external voltage exceeds the diode’s breakdown voltage, the diode is triggered and a current path is established. Excess voltages are then diverted away from sensitive components and dispersed in a controlled manner.

The P2SMA150A-E3/5AT is a unidirectional TVS diode, meaning it can conduct current flow in only one polarity. This diode is specially designed to handle large amounts of current and is capable of withstanding up to 150A peak pulse currents at 122.5V. Due to its high current handling capability and low capacitance, the P2SMA150A-E3/5AT is suitable for high-speed switching applications.

Conclusion

The P2SMA150A-E3/5AT is a TVS diode designed to protect sensitive electronic systems against damage caused by voltage fluctuations. This diode can be used in a variety of applications, from telecommunications to automotive electronics. The diode operates by creating a potential barrier when a certain voltage is applied to its Cathode and Anode terminals.
