The SMPZ3930B-M3/84A is a single Zener diode for circuit protection. It has an operating temperature range of -55°C to +125°C and a capacitance of 50 pF at a voltage of 1.0 mV. The SMPZ3930B-M3/84A is designed to protect a circuit from over-voltage spike, typically caused by ESD pulses, and is suitable for use in automotive and other high-voltage applications.The SMPZ3930B-M3/84A is a single-diode device that functions as a two-terminal, reverse-biased Zener diode. When a reverse-biased current exceeds the Zener breakdown voltage, a voltage drop proportional to the amount of current will appear across the diode terminals. The Zener diode thus acts as a voltage clamp, limiting the voltage to the Zener breakdown voltage.The Zener diode can be used in many applications, and can provide protection from excessive voltage and regulation of current flow. When used as a voltage-clamping device, it acts as a form of circuit protection from overvoltage conditions, such as those caused by electrostatic discharge (ESD) pulses.In automotive applications, the SMPZ3930B-M3/84A can be used to protect the circuit from transients caused by ESD pulses, or to regulate the voltage on the circuit. Because of the wide operating temperature range, the diode is suitable for use in automotive and similar applications, where the extreme temperatures can damage unprotected electronics.The SMPZ3930B-M3/84A is also suitable for a variety of other applications, such as overvoltage and reverse polarity protection, voltage regulation, and current regulation. When used as a voltage regulator, the Zener diode produces a steady voltage across its terminals, regardless of the load current.The SMPZ3930B-M3/84A is a reliable, high-voltage diode, suitable for a variety of circuit protection and voltage regulation applications. With its wide operating temperature range, the diode is ideal for applications in automotive and other high-voltage applications. Owing to its high breakdown voltage, the diode can serve as a reliable circuit protection device, and as a voltage regulator for automotive and similar systems.
