5.0SMDJ90CA

5.0SMDJ90CA is a TVS - Diodes (transient voltage suppressor diode) that is designed to protect electrical systems, such as delicate electronics and integrated circuits, against electrical transients. These diodes are small, fast-acting, voltage-dependent, two-terminal devices that protect against instantaneous voltage changes, known as transients. Transients are high-voltage, short-duration energy pulses, which if left unchecked can overload and destroy a system\'s circuitry.

The 5.0SMDJ90CA has a working voltage of 5.0 Volts, a breakdown voltage of 9.0 Volts, and a maximum peak pulse current of 90 Amps. This TVS diode is typically applied in the automobile, computer, and communication markets in applications such as PC board circuit protection, tachometers, voltage converters, and transceiver protection. It is used for over-voltage, inductive voltage spikes generated from motors, and various types of transients.

The working principle of a TVS diode is based on its breakdown voltage. It has an anode and a cathode end and during normal operation the current flows from the anode to the cathode. When a transient voltage exceeds the breakdown voltage of the diode, it shorts the anode and cathode together. This process then temporarily absorbs the energy associated with the voltage surge. The diode is designed to conduct a limited amount of current at the breakdown voltage, but once the surge is dissipated, the current is decreased and the diode resumes its normal state.

The 5.0SMDJ90CA TVS diode can help protect an electronic device from damage caused by high transients. Its fast response time is among the best in the industry and its ability to dissipate large amounts of energy make it well-suited for protecting sensitive electronic components from the effects of over-voltage transients. Additionally, the low leakage current, high surge capability, and cost-effectiveness make it a popular choice when electrical devices require protection.
