CMPZ5248B TR and its application field and working principle can be categorized as a single Zener diode. A Zener diode is a unique type of diode that permits current to flow in a forward direction like normal, but also can be reverse-biased, allowing current to flow in the reverse direction if the voltage is larger than the rated Zener voltage. This is called the breakdown voltage and can range from a few volts to hundreds.The term “TR” stands for transient voltage suppression, meaning CMPZ5248B TR is designed to suppress transient voltage spikes that can otherwise damage circuits. A spike is a sudden rise in voltage above normal levels, usually as a result of an electrical surge. As an example, when a motor kicks on it can draw power from the supply, creating a spike. Similarly, lightning or a power outage can introduce a surge of electricity back into a circuit. CMPZ5248B TR has its maximum power dissipation at a maximum of 1.5 watts. Maximum working voltage is 48V and maximum clamping voltage is 64V. It features a theoretical current capability of 9A, surge capacity of 1000W, and typical clamping voltage of 64V with an 8/20μs pulse. It also has an operating temperature range of -55°C to 125°C.CMPZ5248B TR’s working principle allows the diode to clamp voltage down to safe levels and provide protection against high voltage transients. When the voltage reaches its specified breakdown voltage, the diode begins to conduct, resulting in the voltage drop with respect to the devices’ clamping voltage. It creates a low voltage region and forces the current to move or flow through the diode instead of the protected circuit. The combination of a low voltage drop across the diode and a high resistance across the diode reduces the chances of the protected circuit sustaining damage. CMPZ5248B TR is used in applications such as power supplies, LCD panels, and mobile phone designs to protect sensitive components from transient voltage spikes. In power supplies, for example, the diode can provide protection from lightning-induced surges and can provide a smoother supply of power, thus increasing the life of electrical components.In conclusion, CMPZ5248B TR is a single Zener diode with a transient voltage suppression rating and is used to protect sensitive components from voltage transients. It features a maximum power dissipation of 1.5 watts, maximum working voltage of 48V, maximum clamping voltage of 64V, and typical clamping voltage of 64V with an 8/20μs pulse, and an operating temperature range of -55°C to 125°C. It’s used mainly in power supplies, LCD panels, and mobile phone designs.
