The SML4735AHE3/61 is a single Zener diode designed by Zetex Technologies. It has a zener reverse voltage of 3.9V and an operating temperature range from -65°C to 150°C. The diode is composed of an N-type junction between two semiconductor layers. The diode is mainly used in applications where a stable voltage is a critical parameter, such as in power regulators, clippers, and ESD protection circuits.

The SML4735AHE3/61 is a popular choice for applications requiring efficient power dissipation with minimal junction capacitance. The device offers a low forward voltage drop, with thermal resistance from junction to ambient of <200 °C/W. The diode also offers effective protection from positive or negative over-voltage transients, with a maximum power dissipation of 5 Watts.

The working principle behind the SML4735AHE3/61 is based on the Zener breakdown effect. When the applied voltage exceeds a certain limit (or Zener voltage) the diode will conduct electricity in the reverse direction. This enables a device to maintain a stable voltage, which is useful in applications such as voltage regulators, clippers, and ESD protection circuits. Essentially, the diode works by establishing an equilibrium between the breakdown voltage and the controlling voltage, ensuring that a certain voltage level is maintained.

The SML4735AHE3/61 is a popular choice for applications that require a high degree of efficiency and stability. Its maximum power dissipation and low junction capacitance make it a versatile diode, able to offer reliable voltage regulation in a range of applications. From power regulators to clippers and ESD protection circuits, the SML4735AHE3/61 can provide the stability needed for these demanding applications.
