Introduction to the SZBZX84C15LT1G

The SZBZX84C15LT1G is a single Zener diode manufactured and distributed by Diodes Incorporated that is designed for use in a wide range of general purpose applications. It is composed of a semiconductor junction and is designed to provide additional protection against electrostatic discharge (ESD), primarily in automotive applications.

Application Fields

The SZBZX84C15LT1G diode is specifically designed for automotive applications, making it ideal for a variety of on-board, in-vehicle or off-board solutions and applications, including:

• Supply voltage and reference voltage stabilization
• Power switching and clocking
• Sensor and signal protection
• Automatic alternator functionality optimizations
• Battery over-voltage shunting protection
• EMI and ESD protection

The device is designed for wide-temperature range operation with an extended operating temperature range from -55°C to + 175°C, making it highly suitable for use in harsh environments.

What’s the Working Principle?

The working principle of the SZBZX84C15LT1G diode is based on the reverse bias of a p-n junction diode. The diode is constructed in a manner that allows it to be reverse biased, where current flows in the reverse direction. When current passes through the diode in the reverse direction, the charge carriers counter flow, which creates a space-charge-region causing a voltage Difference (Vz) known as the Zener voltage. This voltage Difference between the anode and the cathode is referred to as the breakdown voltage and is what allows the diode to stabilize the voltage. The SZBZX84C15LT1G diode is designed to offer a wide Zener voltage range, ranging from 3.0V to 28.0V. Depending on the needs of the application, a specific voltage can be selected to provide the desired stabilization.

Conclusion

The SZBZX84C15LT1G is a single Zener diode manufactured by Diodes Inc. that is designed to provide protection against ESD, primarily in automotive applications. It has a wide temperature range and can be used in harsh environments. The working principle of the device is based on the reverse-bias of a p-n junction diode, where the Zener voltage is used to stabilize the voltage. Depending on the needs of the application, a specific voltage can be selected to provide the desired stabilization.
