onsemi 1SMB5955BT3G is a high-performance Zener diode designed for voltage regulation applications. With a nominal Zener voltage of 180 volts and maximum power dissipation of 3 watts, it provides reliable voltage reference and protection for electronic circuits. This device features a single element chip mounted in a compact surface mount DO-214AA package with 2 pins, enabling easy integration on PCBs with limited space.
The diode operates efficiently across a wide temperature range from -65°C to 150°C, making it suitable for automotive and industrial electronics demanding harsh environmental resistance. A low test current of 2.1 mA ensures precise voltage regulation at the rated Zener voltage, while the maximum Zener impedance of 900 Ω provides voltage stability under varying load conditions. Additionally, the minimal reverse leakage current of 1 μA helps maintain circuit integrity by preventing leakage currents during off-state.
It is commonly deployed in power supply regulation, protection circuits, and voltage clamping applications. This diode contains a single chip element configured specifically for voltage regulation. Its surface mount DO-214AA package supports high-density assembly in compact designs.
Rated maximum operating temperature is 150°C and minimum is -65°C for wide application range. Test current of 2.1 mA sets the diode’s voltage regulation reference point. Maximum power dissipation of 3 W allows for moderate power handling capabilities.
Low reverse leakage current of 1 μA minimizes power loss and circuit noise. Compliant with RoHS and certified to AEC-Q101 ensures quality and safety.
This product is ideal for use in various electronics and industrial applications including automotive, manufacturing, and power electronics sectors. EnvMart offers this high-quality onsemi Zener diode suitable for engineers and designers requiring dependable voltage regulation components.
