7.3 Feature Description

The ESD2CANFD24 is a bidirectional TVS with a high ESD protection level. This device protects the circuit from ESD strikes up to ±25-kV contact and ±25-kV air-gap specified in the IEC 61000-4-2 standard. The device can also handle up to 3.5 A surge current (IEC 61000-4-5 8/20 µs). The I/O capacitance of 2.5-pF (typical) supports a data rate up to 10 Mbps. This clamping device has a small dynamic resistance, which makes the clamping voltage low when the device is actively protecting other circuits. For example, the clamping voltage is only 37 V when the device is taking 3.5 A transient surge current. The breakdown is bidirectional so this protection device is a good fit for CAN which is a differential signal. Low leakage allows the diode to conserve power when working below the VRWM. The temperature range of −55°C to +150°C makes this ESD device work at extensive temperatures in most environments. The leaded SOT-23 package is good for applications requiring automatic optical inspection (AOI).
