TVS or Transient Voltage Suppressors, also known as “clamps” are semiconductor devices that provide a protective function and are designed to limit and divert the unwanted surge current that may otherwise move into the sensitive side of a circuit. They are especially useful for protecting sensitive electronic circuits from external surges due to lightning strikes, or other failure in the external power supply. The BZG04-15TR device is a TVS Diodes designed by Littelfuse for a very specific application field.

The BZG04-15TR is a unidirectional device designed to absorb transients within an operating temperature range of -40°C to +125°C. It is offered in both axial and surface mount formats with a low maximum peak pulse current (IPPM). The device also features a low capacitance of 2.3 to 1.5 pF, making it ideal for applications that require low impedance protection from transients ranging from 200 to 600 volts.

The BZG04-15TR is normally used in the protection of sensitive automotive circuits that are subjected to sudden large voltage transients. This device can be used to protect sensors, microcontroller, and other devices that are commonly used in automotive applications. The low capacitance and maximum peak pulse current of the device prevents it from overheating or causing a short circuit. This makes it ideal for applications in which the environment is harsh and the components cannot be easily replaced.

The working principle of the BZG04-15TR is quite simple. The device will conduct current during normal conduction and will clamp the voltage to the specified value if it is exposed to a large transient or surge. This clamps the transient voltage and helps protect the sensitive components of the application from the unwanted surge.

The BZG04-15TR is a great device for protecting automotive electronics from sudden voltage transients. Its low capacitance and peak pulse current make it an ideal choice for rough environments. It has a wide operating temperature range and is available in both axial and surface mount formats. With these features, it is no wonder why it is so popular in the automotive industry.
