ESDZV5-1BU2 Description

Short technical summary and product information.

The ESDZV5-1BU2 is a bidirectional Zener-based TVS diode designed for transient voltage suppression in general purpose applications. It provides a reverse standoff voltage of 5.5V and clamps at a typical 8V, protecting downstream circuits from overvoltage events.

 

The device is rated for a peak pulse current of 7A (8/20µs) with a peak pulse power dissipation of 70W. Low capacitance of 6pF at 1MHz makes it suitable for high-speed data line protection without significant signal degradation. The diode operates over a junction temperature range of -55°C to 150°C.

 

Housed in a surface mount 0201 (0603 metric) package, the ESDZV5-1BU2 is ideal for space-constrained designs. The supplier device package is designated ST0201. This component does not include power line protection and is intended for general purpose circuit protection.
