TVS – Diodes, also known as Transient Voltage Suppression / Suppressors, or more commonly referred to as Surge Protectors, are specialized semiconductor devices that protect components from destructive voltage transients. The PESD12VS1UAF is a voltage-dependent Transient Voltage Suppression Diode (TVS) with a peak pulse current of 12A (10/1000μs waveform) and a breakdown voltage of 12V (maximum at 27V). It is designed to provide superior performance in applications such as protecting signal and power lines from transient overvoltages.

The PESD12VS1UAF is usually used in automotive power-supply systems, set-top boxes, and other consumer electronics. The device ensures safe and reliable system operation by providing a protective barrier between overloaded and sensitive components. It is also suitable for applications such as transient protection, ESD protection, line protection, and overvoltage protection.

The PESD12VS1UAF is part of a family of TVS diode products that are designed to protect components from damaging transients. It consists of a thin-film, easy-to-solder device with a PESD12VS1UAF design for easy mounting. The device is characterised by an operating temperature range of -65°C to +175°C, with a rated working voltage of -0.5V to + 12V, and a leakage current of 0.9μA @ 12V.

The working principle of the PESD12VS1UAF is simple. When a high-voltage transient arrives at the device, it quickly switches on and redirects the excess energy to ground. This prevents the unwanted overvoltage from damaging the protected components. The avalanche clamping operation of these devices makes them an effective solution for protecting components from voltage transients.

The PESD12VS1UAF is a reliable and cost-effective solution for protecting components against overvoltage transients. It is small in size, has high peak pulse current handling capability, and is RoHS compliant. This makes the device suitable for various automotive and consumer electronics applications where space is limited.
