MMSZ5235B-G3-18

Diodes - Zener - Single

The MMSZ5235B-G3-18 is an 18V, 5.1W Zener diode that belongs to the MMSZ series of Zener diodes from Semtech. It is used in applications that require voltage stabilization, maintaining specific voltage levels and clamping of voltage spikes. This type of diode has a wide variety of applications in automotive, consumer electronics and other commercial electronic circuits.

A Zener diode provides a voltage stabilization function through a simple process. It maintains a stable voltage across its terminals by allowing current to flow in one direction only. This occurs when the applied voltage meets or exceeds the Zener voltage. When a voltage lower than the Zener voltage is applied, the diode remains in the open circuit state.

The MMSZ5235B-G3-18 has several important characteristics that determine its suitability for various applications. The maximum reverse voltage (VR) is 18V, which is the maximum voltage the diode can take before it breaks down. The maximum power dissipation (PD) is 5.1W which indicates the maximum power the diode can dissipate before it is destroyed. The maximum forward voltage drop is 0.89V and the maximum reverse current (IR) is 5mA. Its temperature range is from -65°C to 175°C, which enables it to be used in a variety of environmental conditions.

The MMSZ5235B-G3-18 can be used in a variety of applications that require voltage regulation and clamping of voltage spikes. Some of these include automotive and consumer electronics circuits, DC-DC converters, battery chargers, switching power supplies, and AC/DC line protection.
