Introduction to SA15AG

SA15AG is a type of TVS – Diode that is designed to protect communications lines and other sensitive electronic components from overvoltage transients. The SA15AG is a low capacitance unidirectional diode designed to protect against electro-static discharge (ESD) and lightning strikes. This diode features a temperature-independent capacitance of less than 4pF.

Application Field of SA15AG

The SA15AG is widely used in all industries in which high-speed data transmission is vital, including networking, telecommunications, automotive, consumer electronics, and more. It is commonly used in Ethernet, USB, Audio, HDMI, and other high-speed I/O interfaces, as well as point-to-point and point-to-multipoint applications. The SA15AG is also an ideal choice for power supply circuits, relays, and other components that are vulnerable to overvoltage transients.

Working Principle of SA15AG

The SA15AG utilizes a Zener Diode’s avalanche breakdown mechanism to produce a unidirectional electrical current. It acts as a surge and lightning protector by limiting the current that can be passed through the circuit. As soon as the voltage exceeds a defined threshold, the diode begins to conduct and allows the current to flow. The forward voltage drop of the diode is usually about 0.7 V, meaning that the current must be limited to the value set by this voltage to keep the protected circuit safe. The SA15AG is also designed to protect against ESD. When exposed to an ESD event, the diode begins to conduct, limiting the current that can be conducted and preventing further damage to the circuit.

Conclusion

SA15AG is an integral component for all modern electronics, providing protection against ESD and lightning strikes. It is a low capacitance unidirectional diode with a temperature-independent capacitance of less than 4pF. In addition, the SA15AG is widely used in all industries in which high-speed data transmission is vital, including networking, telecommunications, automotive, consumer electronics, and more. The diode utilizes the avalanche breakdown mechanism of a Zener diode to produce a unidirectional electrical current, thereby limiting the current that can be passed through the circuit. The forward voltage drop of the diode is usually about 0.7 V, meaning that the current must be limited to the value set by this voltage to keep the protected circuit safe.
