This device belongs to the SZBZX family of Zener diodes and is specifically designed for high voltage applications. It has a break-down voltage of 4.7 V and is available in a 4-pin SOT-223 package with a maximum surge current of 500 mA. The device features a guard ring for improved device stability, a wide operating temperature range from – 55°C to + 125°C, and a broad spectrum of electrical and thermal characteristics that make it ideal for high voltage applications.

The SZBZX84C47LT3G diode is ideal for applications requiring high voltage protection or voltage regulation, such as in power supplies, DC-DC converters, multi-voltage logic circuits, and automotive electronic systems.The operation of the SZBZX84C47LT3G diode is based on the Zener breakdown principle. In this principle, when a reverse voltage is applied to the diode, a very thin depletion layer is formed between the N-type and P-type materials. As the reverse voltage increases, the depletion layer becomes thicker and eventually reaches the Zener breakdown voltage, at which point the diode starts to conduct in the reverse direction. As the reverse voltage continues to increase, the amount of current that flows through the diode increases exponentially. This Zener voltage helps provide stable voltage regulation and protection from electrical surges.In addition to its primary application of voltage regulation, the SZBZX84C47LT3G can also be used for reverse voltage protection, signal level restoration, noise suppression, transient voltage absorber and as part of a voltage multiplier circuit.

The SZBZX84C47LT3G offers several advantages to design engineers. Its 4-pin SOT-223 package is small and easy to mount, which makes it perfect for applications where space is limited. The large guard ring helps to reduce the probability of latch-up and breakdown, while the wide operating temperature range makes it suitable for high temperature environments. The wide current range ensures good thermal stability, while the high surge current capability ensures the diode can stand up to short-term over-voltage.
