TVS - diodes are devices that are primarily used for protection against transient overvoltage in power and data lines. The SMBJ85CA-E3/52 is a popular TVS - Diode designed for protection against a variety of transient overvoltages. The device is rated for 85 volts and can withstand power surges of up to 40 Amps.

The SMBJ85CA-E3/52 is suitable for a wide range of applications ranging from automotive to consumer electronics. In automotive, the device can be used to protect the onboard electronics from transients caused by engine start/stop, sunroof closure, or electrical noise from the alternator. The protective capability of the device extends to semiconductor and printed circuit board components found in consumer electronics, making it an ideal solution for surge and transient protection.

The working principle of the SMBJ85CA-E3/52 is based on a semiconductor junction in which current naturally flows from the anode (positive) to the cathode (negative). The operation of the diode is determined by the forward and reverse voltage ratings of the diode junction. In a transient overvoltage situation, the forward voltage rating is exceeded, causing a current to flow in the reverse direction, thus entering the protection mode.

The SMBJ85CA-E3/52 is designed for protection against a variety of transient overvoltage surges. The device is rated for 85 volts and can withstand power surges of up to 40 Amps. The maximum leakage current is less than 10 µA, making it an ideal solution for protecting against ESD (electrostatic discharge). The device features a high surge capability and low clamping voltage, which ensures optimal protection without compromising performance.

The SMBJ85CA-E3/52 is designed to provide reliable protection against transient overvoltage and power surges. The device can handle up to 40 Amps of current and features a low leakage current of 10 µA. The device is suitable for a wide range of applications, including automotive and consumer electronics. The protective capability of the device makes it an ideal solution for surge and transient protection.
