SMBJ26

TVS (transient voltage suppression) diodes are one type of surge protective devices used to protect electronics and electrical equipment from damage due to electrostatic discharge, transients and overvoltage. The SMBJ26 is a fast response, unidirectional, high peak current television suppressor diode designed for preventing damage and malfunction caused by voltage transients along lines influencing communication systems, computers, medical equipment, and industrial systems.

The SMBJ26 is designed for use in TVs, computer devices, and communications lines. It has a peak pulse current rating of 26A and is rated for a maximum peak pulse power dissipation requirement of 400W or 1.3kW for a 10/1000 microsecond waveform. It operates from -55°C to +150°C and comes in a small SOD-123 package which measures 2.3mm x 2.3mm x 1.3mm.

SMBJ26 working principle is as follows. The SMBJ26 utilizes a large, swift voltage clamping action to suppress transients. When a surge exceeds the device’s breakdown voltage of 5.5V, an avalanche process begins, which rapidly reduces the surge current. The device also has a low capacitance on order of 0.47pf which allows it to respond quickly to surges. The SMBJ26 has a fast clamping response time coupled with an internal diagram which allows the clamping to occur at voltages significantly below its breakdown voltage.

The SMBJ26 is used to protect electronic equipment from transient over voltage conditions. It can be used in a variety of applications, from AC/DC power adapters, telecom line protection, and low power computer boards, to data lines, power supplies, and consumer electronics. The SMBJ26 diode is an ideal choice for low power applications where space is limited in the circuit.

The SMBJ26 diode is a fast-acting diode with high peak current ratings. It is capable of suppressing high energy transients and overvoltage spikes that occur in the power and communication lines. The SMBJ26 is a cost-effective solution for applications requiring surge protection and is suitable for use in a variety of applications such as TVs, computers, medical equipment, communications, and industrial applications. It is a good choice, especially for low power applications, due to its small size and fast clamping response time.

In conclusion, the SMBJ26 is a fast-acting diode that is designed to protect electronic circuits from damage due to overvoltage transients. It features a high pulse current rating, a low capacitance, and a fast clamping response time. The SMBJ26 is well-suited for a wide range of low power applications and is an affordable solution for surge protection in electronics, telecoms, medical devices, and industrial applications.
