The 1N5935CPE3/TR12 is a single Zener diode with a reverse breakdown voltage of 9.3V. Zener diodes are one of the most common types of diodes used in a variety of electronic applications. By hinging its breakdown voltage at a precise value, a Zener diode can regulate voltage levels in electronic circuits. Zener diodes are used in a wide range of applications, including voltage regulation, ESD protection, current sensing and surge protection.

The 1N5935CPE3/TR12 consists of a semiconductor material connecting the anode and cathode. As current passes through the semiconductor, electrons flow from the anode to the cathode and holes flow in the opposite direction. When an electrical field of a particular magnitude is applied in the reverse direction across the diode, the applied electric field causes electrons to become liberated from the atoms and creates an avalanche breakdown, allowing current to flow in the forward direction. This is the breakdown voltage of a Zener diode, and is referred to as its Zener voltage. This Zener voltage is dependent on the semiconductor material used, the size and shape of the diode, the temperature and the applied electric field.

The 1N5935CPE3/TR12 is typically used in low-voltage power supplies, voltage regulators and surge suppression circuits. The diode can also be used in battery chargers and as current detectors, because the diode can sense a voltage drop across a resistor. This voltage drop can be used to turn on or off a circuit. Zener diodes are also some of the most common components used in ESD protection designs, where they clamp transient voltages to safe levels.

The 1N5935CPE3/TR12 is also ideal for electrostatic discharge (ESD) protection. Zener diodes can protect sensitive components in electronic circuits from ESD damage. When subjected to a voltage transient, the Zener diode quickly conducts current away from the sensitive component, preventing it from receiving a direct ESD impact. Zener diodes are able to do this because of their reverse breakdown voltage. The Zener voltage is typically slightly lower than the desired voltage, allowing the diode to conduct from the instant the voltage exceeds the desired level.

The 1N5935CPE3/TR12 is an example of a single Zener diode, which has the characteristics of a standard diode and the ability to regulate voltage levels. It is widely used in a variety of applications and can provide reliable protection for sensitive components by instantaneously conducting currents away from a voltage transient. By using the right Zener diode, design engineers can ensure that their circuits stay within the desired operating voltage range and remain safe from ESD shock.
