TVS - Diodes

TVS (Transient Voltage Suppressor) diodes protect sensitive electronics and components from the damaging effects of over-voltage transients. They absorb the excess energy in voltage spikes, and disintegrates the extra charge, thus protecting the electronic equipment from failure. TVS diodes are the most widely used component to protect against over-voltage transients and increase the working lifetime of electronic equipment.

MAP5KE6.5A application field and working principle

The MAP5KE6.5A is a silicon avalanche diode from NXP Semiconductor that is designed specifically for TVS applications. This component is designed with an integrated ESD (electrostatic discharge) protection diode and protection resistor to ensure that any over-voltage transients are quickly discharged and dissipated away from sensitive components. The diode is available in a TO-220 package, thus it can easily fit into any existing circuit and provides excellent electrical protection.

The MAP5KE6.5A is ideal for protection applications in consumer electronics, commercial industrial equipment, telecommunications, and automotive industries. It is capable of protecting against over-voltage transients and is highly reliable and robust enough to withstand harsh environments and varying temperatures. It is capable of withstanding up to 6.5A pulse current up to 8/20μs and has very low leakage current.

The working principle for the MAP5KE6.5A can be explained as follows. When an over-voltage transient occurs, the diode’s integrated protection diode switches on, and starts to conduct the current. The current then passes through the diode’s integrated anti-parallel protection resistor, and the resistor dissipates the over-voltage transient energy, protecting the circuit. Due to the diode’s low capacitance, the circuit is protected from any additional transient interference.

The MAP5KE6.5A is also an ideal choice for protection against electrostatic discharge (ESD) and lightning-induced transients. It is capable of withstanding ESD pulses up to 1J and can also absorb lightning-induced transients. With this device in place, sensitive electronic components will be protected from lightning-induced voltage spikes.

In short, the MAP5KE6.5A is a robust, reliable, and highly efficient TVS diode from NXP Semiconductor that is designed specifically for over-voltage protection. It is capable of withstanding high pulse current, and is also suitable for ESD and lightning-induced transient protection. Its integrated protection diode and resistor help to quickly dissipate any over-voltage, ensuring that sensitive components and equipment are effectively protected.
