ESD051-1BF4 Description

Short technical summary and product information.

The ESD051-1BF4 is a Zener TVS diode from STMicroelectronics designed for general purpose ESD protection. It features a 5V reverse standoff voltage (VRWM) and a typical clamping voltage of 11V. With a peak pulse current rating of 10A (8/20µs) and peak pulse power of 110W, it provides robust transient voltage suppression.

 

This diode is a single bidirectional channel device with a low capacitance of 45pF at 1MHz, making it suitable for high-speed data line protection. It is surface mount packaged in a compact 0201 (0603 Metric) case with supplier device package ST0201. The operating temperature range is -55°C to 150°C (TJ).

 

The ESD051-1BF4 is RoHS3 compliant and REACH unaffected, though environmental compliance has not been independently verified. It does not include power line protection. Ideal for portable electronics, mobile devices, and signal line protection where space is at a premium.
