TVS (Transient Voltage Suppressor) diodes, also known as unidirectional protection diodes, have been increasingly used for protection of power lines, sensitive on-chip power interfaces and data buses. DT2636-04S-7 is a unidirectional transient voltage suppressor diode with a wide viable range and fast response. It employs a unique silicon-oxide transient voltage suppression (TVS) technology that provides an extremely low capacitance of 0.017 pF for very fast responses up to 500 V/84 nano seconds. It is manufactured with a wide range of voltages, from 5 volts to 24 volts and provides an operating temperature range from -40°C to +150°C.

The DT2636-04S-7 is typically used in applications such as:

• Protection of sensitive circuits or components from over-voltage and transients.
• Power line protection.
• Data line protection.
• USB interface protection.
• Input protection for power MOSFETs.
• Suppression of radio-frequency interference.

The principle of the DT2636-04S-7’s operation is fairly straightforward. When the diode is exposed to a voltage surge greater than its peak avalanche voltage (V(P)) – typically between 10 and 20V, depending on the device – the diode becomes conductive and dissipates energy to ground, thus absorbing the transient. Thus, the device acts like an electronic fuse, clamping the voltage and allowing for safe passage of current. After the surge has been absorbed, the diode automatically restores its normal zero-voltage state after the transient event subsides.

The DT2636-04S-7 provides several advantages for transient protection applications, such as:

• Low capacitance, fast response time.
• High peak energy absorption capability.
• Low leakage current.
• Tight manufacturing tolerance.
• Wide variety of packages.

The device is supplied in a surface-mount chip package with a lead-frame structure. The lead-frame structure allows for easy assembly and robust reliability. The package\'s small size also helps minimize the parasitic capacitance between the device and the circuit components that it is protecting.

The DT2636-04S-7 provides reliable protection against voltage surges and transients, thus making it an ideal choice for power and data line protection. The device also offers excellent thermal stability, low capacitance, and high peak energy absorption capability, making it suitable for a wide variety of applications. With its small package size, wide temperature range, and robust assembly capabilities, the device is a great option for any customer seeking to add an extra layer of security against voltage transients.
