1SMA5933HM2G

The 1SMA5933HM2G is a single Zener diode, mainly used for protecting circuits from transient overvoltage or for providing a stable reference voltage. It uses an optimized planar processing technology and its main purpose is as an electronic component for electro-optical coupling. These components are also used for voltage regulation, such as when used as a voltage regulator in a voltage-power supply circuit.

The 1SMA5933HM2G diode is an excellent choice for applications that require peak reverse voltages (VR) of 33V or lower and continuous reverse voltage (VF) of 15V. Its avalanche characteristics make it ideal for fast switching applications in high-voltage circuits. It is designed to clamp transient voltage over-voltage, and is available in various acceptable current handling capabilities.

The 1SMA5933HM2G working principle is fairly simple. When it is operating in the reverse bias, it will have a breakdown voltage when the applied voltage across it reaches a critical voltage level called the Zener voltage. When the Zener voltage is reached, the Zener diode conducts and regulates the voltage across itself to the Zener voltage level and then limits the amount of current that can flow through it. This voltage regulation is achieved regardless of the amount of current that is passing through it.

The 1SMA5933HM2G diode features low power dissipation, low leakage current, and high breakdown voltage. It is usually rated for its reverse breakdown voltage (VR) of 33V and reverse current (IR) of 6mA. The temperature range in which the diode can operate is -40°C to +150°C. The maximum thermal resistance of the 1SMA5933HM2G is 55°C/W.

In summary, the 1SMA5933HM2G is a single Zener diode, used primarily for voltage regulation or protection from transient overvoltage in electronic circuits. It is capable of handling peak reverse voltages (VR) of 33V or less and continuous reverse voltage (VF) of 15V. Its Zener voltage and breakdown voltage ensure efficient voltage regulation, and its low power dissipation and low leakage current makes it ideal for fast switching applications in high-voltage circuits. The diode has a temperature range of -40°C to +150°C and a maximum thermal resistance of 55°C/W.
