SA20A-TP

TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are widely used in electrical circuits for suppressing voltage transients. They are designed to provide protection against damaging voltage spikes, usually caused by static electricity, induction, ESD (electrostatic discharge), etc. TVS diodes provide a fast response to sudden voltage increase, limiting the voltage overshoot and clamping the transient voltage to an acceptable level. The primary function of TVS diodes is to protect sensitive circuitry and components from damage due to transient spikes.

SA20A-TP - Application field and Working Principle

The SA20A-TP is an ultra-low-voltage transient voltage suppressor diode designed for use in portable systems such as cellular phones and PDAs. The diode is very small and can be incorporated into the PCB surface without space restrictions. The transient voltage protection of the SA20A-TP diode is provided by its high PIV (peak inverse voltage) and fast response time. It has a non-linear V-I (Voltage-Current) characteristic which helps to suppress voltage spikes up to the PIV. It also has a low breakdown voltage.

The working principle of the SA20A-TP is very simple. When a voltage spike is applied, the diode begins conducting and starts allowing current to pass through it. As the voltage reaches the PIV level, the current starts to reduce and reaches zero as soon as the voltage reaches the breakdown voltage, thus limiting the voltage to a safe level. It can be used for both over-voltage and under-voltage protection. In addition, it has high surge capacity and fast response times.

The SA20A-TP diode is suitable for both transient and ESD protection and it is also widely used in consumer electronics. It is used to protect sensitive components from voltage spikes and transient transients near the circuit\'s critical points. It is also compatible with most digital logic techniques and is suitable for various applications such as low voltage protection for ICs, ESD protection, power supply protection, device protection, and automotive applications.

The SA20A-TP diode is also used in various consumer electronics products, such as cell phones, laptops, and digital cameras, as they provide reliable transient and ESD protection. It is designed to be used in systems with small amounts of power and does not require a large heatsink or additional cooling. It also has a high surge capacity and fast response times.

The SA20A-TP is an effective and reliable means of protecting sensitive components and devices from stray voltage transients and ESD events. It is a low-voltage, high-capacity device with fast response times, and can easily be integrated into any system.
