STIEC45-33AS Description

Short technical summary and product information.

The STIEC45-33AS is a unidirectional Zener TVS diode designed for general purpose circuit protection. It features a reverse standoff voltage of 33V and a clamping voltage of 59V, providing robust overvoltage protection. The device can handle a peak pulse current of 500A under an 8/20µs waveform, making it suitable for transient voltage suppression in a variety of applications.

 

This TVS diode is surface mountable and comes in a DO-214AB (SMC) package, which is widely used for power and protection components. It operates over a junction temperature range of -55°C to 150°C, ensuring reliable performance in harsh environments. The component is RoHS3 compliant and has an MSL rating of 1 (unlimited), simplifying handling and assembly.

 

With its single unidirectional channel and Zener technology, the STIEC45-33AS is ideal for protecting sensitive electronics from voltage spikes and ESD events. It is commonly used in power supply lines, communication interfaces, and industrial control systems where space and reliability are critical.
