Working Principle

The PESD15VL2BT,215 is a low capacitance bidirectional TVS diode. It consists of a Zener diode with a PN junction in the opposite direction. When a positive transient voltage is applied, the Zener diode conducts and the PN junction block the transient voltage. The Zener diode dissipates the transient energy, while the PN junction blocks it. When a negative transient voltage is applied, the PN junction conducts and the Zener diode block it.

The PESD15VL2BT,215’s standard peak pulse power rating of 75 Watts enables it to absorb large transients without permanent damage. Its low capacitance design reduces noise during high speed data switching, and its high surge current capability ensures that the PESD15VL2BT,215 can reach its full clamping voltage before failing.

The PESD15VL2BT,215’s low clamping voltage makes it suitable for protection of sensitive circuits and components. The overshoot current capability ensures consistent performance in high power, high energy applications.
