1N5338B/TR8

The 1N5338B/TR8 is a silicon, 500mW zener diode which is ideal for general purpose usage and for test and measurement applications. With a reverse breakdown voltage of 6.2V, this diode is an excellent choice for the circuit needing a low voltage power supply. When in reverse bias overvoltage, it can limit to the clamping voltage before breakdown. The 1N5338B/TR8 comes in the TO-92 package and is capable of handling up to 200mA of peak current.

The very low 6.2V breakdown voltage of the 1N5338B/TR8 makes this diode an ideal solution for many applications. It is frequently used in the construction of low power DC/DC converters, transient voltage suppressors, and other devices designed to regulate the voltage of a DC power source. Its low reverse breakdown voltage also makes it useful in testing and measurement circuit configuration.

The 1N5338B/TR8 zener diode works on a principle of voltage-dependent breakdown. As the reverse voltage on the diode increases, breakdown occurs when the electric field in the diode reaches a value which is proportional to the depletion width. As current builds up, the depletion width continues to widen, and eventually the voltage reaches a point where it is enough to cause the diode to break down. The breakdown voltage of a zener diode will remain constant until the current is greater than the zener impedance, at which point the zener voltage will start to decrease.

Additionally, 1N5338B/TR8 diodes have high transient surge power capability. This helps protect the diode from short-term, high-voltage surges that may occur during power switching cycles. This transience capability also makes it ideal for use in power supply circuits, where it can help clamp off any transient that may occur during power-up or power-readout conditions.

The 1N5338B/TR8 is suitable for a variety of applications, including voltage clamping, voltage regulation, and test and measurement. Its low 6.2V reverse breakdown voltage makes it ideal for low voltage power supplies, while its transience capability makes it well suited for use in power supply circuits. With its excellent performance characteristics, the 1N5338B/TR8 is an excellent choice for circuit protection and test/measurement applications.
