JAN1N4970CUS

Diodes - Zener - Single

The JAN1N4970CUS is a Single Zener Diode from the engineering products line of NTE Electronics. This diode is an efficient, two-terminal electronic device used to limit higher voltages across electrical circuits. The JAN1N4970CUS has an average junction capacitance of 770pF and an avalanche breakdown voltage of 45V. The forward voltage at 25°C is 1.1V.

The most typical application for the JAN1N4970CUS is for transient voltage suppression (TVS) protection for electrical circuit lines. In a typical circuit, the JAN1N4970CUS is usually connected between the power source and ground. This creates a Zener effect across the diode, directing the power source to a safe level and protecting the rest of the circuit from over-voltage damage.

In order to handle large voltage spikes, the JAN1N4970CUS diode has a dynamic rating of 150W and can handle current up to 5A. It is designed to clamped the transient voltage protection at 45V in the reverse direction, while making the forward bias signal allowed within its breakdown voltage. This effectively limits the voltage acting on the circuit, reducing the risk of disruption due to overvoltage.

When connected to the power supply, the JAN1N4970CUS becomes highly capacitive. This allows it to prevent high amplitude, ringing voltage transients. It filters out overly large voltage signals, allowing only a steady peak mean voltage to pass through to the rest of the circuit. This helps keep the circuit safe, even during surges in power.

The JAN1N4970CUS Zener Diode is also often used as a current regulator in various electrical applications. When connected to a power source, the diode acts like a voltage divider, regulating the amount of current flowing through it. This helps maintain a steady power level, preventing large, damaging current spikes from occurring.

The JAN1N4970CUS is perfect for any application that requires a strong Voltage or Current regulator. Its versatile design and robust construction makes it highly reliable and suitable for high-power applications. Whether used as a Voltage or Current regulator, the JAN1N4970CUS is sure to provide reliable protection for any electrical circuit.
