TVS (Transient Voltage Suppressor) diodes are an important element in the protection circuit of electronic devices. The 1.5KE18A B0G TVS diode is a very common and reliable component in this regard. It is a unidirectional TVS diode type and provides circuit protection against voltage transients caused by lightning, electrostatic discharge (ESD) and other transient events.

The 1.5KE18A B0G has a breakdown voltage of 18 volts and a reverse voltage rating of 5.0 volts. It can dissipate energy up to 350 Watt and is available in SMA or DO-201 package types. The diode also has a clamping voltage of 33 volts and a peak pulse current of 30 Amps.

The 1.5KE18A B0G is mainly used in industrial, automotive and consumer applications. It is suitable for protecting sensitive semiconductor devices against voltage transients from harmful electromagnetic interference (EMI) and static electricity. The diode can also be used for applications such as data lines, automotive relays and power supplies.

The working principle of the 1.5KE18A B0G is quite simple. The diode offers protection against overvoltage transients by clamping the input voltage to a safe voltage level. This is done by operating in an avalanche breakdown mechanism by quickly switching on the diode when a voltage above the breakdown voltage is applied to it. The diode is then able to reduce the voltage to a safe level within a short duration of time.

The 1.5KE18A B0G also offers protection against current surges by clamping the voltage with a small reverse bias voltage of 5v. When a large surge is applied, the reverse bias is increased, the diode clamps off and the excess current is shunted to ground. This prevents the voltage from rising to an unsafe level and reduces the current to a safe level.

The 1.5KE18A B0G is a reliable component that offers excellent protection against voltage transients and current surges. It is a cost-effective solution that allows for the protection of sensitive semiconductor devices. It is available in various package sizes and is suitable for use in a wide range of applications.
