مقدمة المنتج:1SMA5931BT3G مقدمة المنتج

The 1SMA5931BT3G from onsemi is a 1.5 Watt surface mount Zener voltage regulator diode from the 1SMA59xxBT3G series. It provides a nominal Zener voltage of 18 V with 5% tolerance. The device features ESD protection exceeding 16 kV per Human Body Model, AEC-Q101 qualification for automotive applications, and a low-profile SMA package ideal for automated assembly. The flat handling surface ensures accurate pick-and-place positioning.

مبدأ العمل:1SMA5931BT3G مبدأ العمل

The 1SMA5931BT3G operates as a Zener diode in reverse breakdown mode. When the reverse voltage exceeds the Zener breakdown voltage of 18 V, the diode conducts and maintains a stable voltage across its terminals with low dynamic impedance of 12 Ohms. This voltage regulation characteristic makes it suitable for protecting sensitive circuitry from voltage transients and providing stable reference voltages. The device handles up to 1.5 W of power dissipation through its SMA package.
