7.3.6 DC Breakdown Voltage

The DC breakdown voltage between the IO pins is a minimum of ± 25.5 V. This protects sensitive equipment

from surges above the reverse standoff voltage of ± 24 V.

7.3.7 Ultra Low Leakage Current

The IO pins feature an ultra-low leakage current of ± 50 nA (maximum) with a bias of ± 24 V.

7.3.8 Clamping Voltage

The IO pins feature an ESD clamp that is capable of clamping the voltage to 37 V (IPP = 3.5 A) and 36 V (IPP =

16 A for TLP).

7.3.9 Industry Standard Leaded Packages

This device features an industry standard SOT-23 (DBZ) leaded package for automatic optical inspection (AOI).

7.4 Device Functional Modes

The ESD2CANFD24 is a dual channel passive clamp that has low leakage during normal operation when the

voltage between pin 1 or pin 2 and pin 3 is below VRWM, and activates when the voltage between pin 1 or pin

2 and pin 3 goes above VBR. During IEC 61000-4-2 ESD events, transient voltages as high as ±25 kV can be

clamped on either channel. When the voltages on the protected lines fall below the VHOLD, the device reverts

back to the low leakage passive state.
