SMBJ5930BE3/TR13

Diodes are electrical components primarily used to regulate or control the flow of current in a circuit. Zener or voltage reference diodes are one type of diode, specifically designed to provide a predetermined reference voltage or current. The SMBJ5930BE3/TR13 is a single Zener diode, intended for use in a variety of commercial, industrial, and laboratory applications.

The SMBJ5930BE3/TR13 has peak working reverse power dissipation (PW) of 400 mW, high peak working voltage (UW) of[2] 593 V and a peak working current (AI) of 200 mA. The device has a breakdown voltage (BV) of 590 V, a maximum zener impedance zzt at 50 mA of 4.8 ohms and a maximum reverse leakage current I of 10 μA at 590 V.

This Zener diode is primarily used in a variety of commercial and industrial applications and is suitable for use in circuits requiring low voltage regulation. Some typical applications are: voltage regulation and clamping, DC-DC and AC-DC converters, transient suppression, AC voltage limiters, voltage references, switch mode power supplies, medical instruments, and automotive systems.

The working principle of the SMBJ5930BE3/TR13 involves a breakdown voltage in the reverse-biased direction that depends on the amount of reverse bias applied. When currents are applied to the Zener diode that are higher than the zener current, the voltage across the diode is clamped to the zener voltage, producing a regulated output. This is the reverse breakdown effect on which the device relies.

The inputs and outputs on the device are typically protected from overvoltage and reverse-energy effects, allowing it to operate at high efficiency and low noise. Additionally, as the device has low capacitance, it can be used in high-frequency RF circuits.

The SMBJ5930BE3/TR13 is a useful and versatile device, providing a range of commercial and industrial applications with high-efficiency, low-noise voltage or current regulation. It is ideal for use in power converters, high-frequency RF circuits, switch mode power supplies and medical instruments.
