MAP4KE91CA

TVS (Transient Voltage Suppressor) diodes are an important component of any electrical system used for protecting the system from electrical overstress caused by voltage transients. A voltage transient is a momentary, rapid increase in voltage and is usually caused by lightning, automotive transients, surge inductive noise or components switching on and off unexpectedly. The MAP4KE91CA is a multi-pass transistor array created specifically to protect sensitive circuitry such as data lines, pin drivers and gate arrays from these transients.

The MAP4KE91CA consists of four NPN transistors which are rated for peak pulse voltages up to 15kV, providing protection of up to 1.5kV when connected to the power source. It has a low dynamic resistance of 0.3 ohms, which allows a current up to 7A for a low impedance connection. This small size and low resistance allows the MAP4KE91CA to be used in a multitude of applications including electro-mechanical protecting, power line conditioning and automotive transients.

One of the most impressive features of the MAP4KE91CA is its working principle. When an electrical transient occurs, the four NPN transistors act as a high voltage switch, connecting the positive voltage to the negative voltage. This creates a short circuit connection between the two, allowing the current flow to be limited and re-directed away from the more sensitive components. The MAP4KE91CA has an extremely fast response time, making it the ideal choice for high speed applications such as cell phones, GPS systems and digital cameras.

The MAP4KE91CA is the perfect choice for any application that requires protection from electrical transients. Its small size and low resistance make it ideal for use in a wide range of applications, and its fast response time makes it suitable for high speed applications. The MAP4KE91CA is an important component for any system that requires protection from electrical overstress, providing a reliable and cost effective solution.
