PTVS7V5Z1USKYL Circuit Protection

TVS - Diodes

The PTVS7V5Z1USKYL is a voltage suppressor diode commonly known as a transient voltage suppressor (TVS). It is used as an active protection device to protect sensitive electronic components such as ICs, transistors, passive devices such as resistors, capacitors, and power supplies during high current and/or voltage surges caused by lightning, emp (electromagnetic pulse) threats, electrostatic discharge (ESD), and other possibilities.

TVS diodes are primarily used in applications such as automotive electronics, telecommunications, motor control, and power conversion. In these cases, TVS diodes offer superior protection of circuits and components, as they provide a higher level of protection than traditional single-component passive devices such as fuses, transient voltage surge suppressors (TVSS) or even spark-gap suppressors.

PTVS7V5Z1USKYL is an unidirectional diode, which allows current to flow in one direction only. It is an axial lead type diode with a rugged glass body. Its peak power dissipation capability is 700W with working voltage from 7V to 200V. The response time is <1 ns, and its clamping voltage is 5.1V. The TVS also operates within a wide range of operating temperatures (-55°C to +150°C), has a low reverse standby current leakage (<1 μA), and low capacitance (2.5 pF). The TVS diode also has a robust EMI/RFI noise immunity of 41 dB.

The PTVS7V5Z1USKYL is widely used in many applications that needs to protect sensitive circuits and components from Voltage transients and surge related threats. Its small size, low capacitance, high surge capability, fast response time, and wide operating temperature range make it an ideal choice for many applications. For example, in telecommunications, it is used to protect against lightning, ESD, EMI/RFI, and high voltage transients, while in motor control applications, it is used to protect against overvoltage, short circuit/overload protection, and lightning strikes.

In addition, TVS diodes are also used in power conversion applications such as power converters, switchers and inverters. The PTVS7V5Z1USKYL is commonly used to provide transient voltage suppression by absorbing overvoltage transients and dissipating the energy as heat. The device is typically connected to the power supply input line and dissipates transient energy without affecting or altering the normal input line voltage. It also provides circuit protection from overvoltage transients, and has a very fast response time (<1 ns) ensuring the protection circuit does not suffer any significant damage.

The PTVS7V5Z1USKYL has a wide range of applications and is suitable for use in a variety of industries. Its reliable and robust protection for sensitive circuitry makes it an ideal choice for industrial, automotive, and consumer electronics applications. It is also perfect for applications in the medical device industry, where high reliability and safety are paramount.
