Specifications

The DF2S5.1FS features a reverse stand-off voltage of 5.1V and a peak pulse power dissipation of typically around 100W, depending on the test conditions. It is typically available in a small surface mount package, such as a SOD-923 or similar, for easy integration into circuit boards. The diode's low clamping voltage ensures that the voltage seen by the protected circuit remains within safe operating limits during a transient event. The fast response time enables the diode to quickly clamp transient voltages, preventing damage to sensitive components. This device is designed to meet industry standards for ESD and surge protection.
