SMCJ48A-E3/57T

SMCJ48A-E3/57T is a popular surface mount Transient Voltage Suppressor (TVS) diode. It is designed to protect sensitive electronic components from destructive voltage transients induced by lightning and other voltage transients generated in an electrical system. This diode has a bidirectional mode operation that helps it react fast to transient events. It is a unidirectional device, meaning that it conducts electrical current in only one direction.

The SMCJ48A-E3/57T has an rated breakover voltage of 48 V and a maximum rated standoff voltage of 57 V. This diode has a maximum clamping voltage of 62.7 V at a peak current of 34 A. It has a breakdown voltage range of 40 V to 60 V. It is capable of handling peak pulse currents up to 150 A. It also provides fast response times to transient events, with a typical response time of 1.5 ns.

The SMCJ48A-E3/57T is used in a variety of applications. It is commonly found on circuit boards that control motors, AC/DC, HVAC, power supplies, and AC and DC circuits. It is also found on printed circuit boards for electronic equipment and telecommunications equipment. Additionally, this diode is frequently used on aircraft, automotive, and other industrial applications.

This diode is designed to operate under normal conditions, with a low forward voltage drop. It has a Pb-free finish, which is composed of matte-tin, nickel, and other metals. This helps to protect it from moisture, corrosion, and other environmental factors that can cause wear and tear. The diode is also RoHS and REACH compliant.

The working principle of the SMCJ48A-E3/57T is simple. When the supply voltage rises above its nominal operating voltage, the diode starts to conduct. This causes the voltage to drop, thus providing protection for the sensitive electronic component from the transient voltage surge. When the voltage drops back to a safe level, the diode shuts off and the normal operating conditions can resume. By rapidly responding to voltage transients and surges, the SMCJ48A-E3/57T can effectively provide protection from damaging current spikes.

The SMCJ48A-E3/57T is a versatile and reliable component that is well-suited for a variety of applications. Its wide range of operating voltage, low forward voltage drop, fast response time, and reliable construction make it a great choice for protecting sensitive electronic components from destructive transient voltage events. With its flexible operating characteristics and performance features, it is easy to see why the SMCJ48A-E3/57T is such a popular component in the TVS diode market.
