7.3 Feature Description

The ESD752 and ESD762 are bidirectional TVS diodes with a high ESD protection level. This device protects the circuit from ESD strikes up to ±30-kV or ±20-kV contact and ±30-kV or ±20-kV air-gap respectively as specified in the IEC 61000-4-2 standard. The ESD752 and ESD762 can also handle up to 5.7 A or 2.5 A of surge current (IEC 61000-4-5 8/20 µs) respectively. The I/O capacitance of 3 pF or 1.7 pF (typical) are suitable for USB power delivery slower speed signals and industrial applications. These clamping devices have a small dynamic resistance, which makes the clamping voltage low when the device is actively protecting other circuits.

For example, the ESD752 clamping voltage is only 37 V when the device is taking 5.7 A transient current. The breakdown is bidirectional so these protection devices are a good fit for applications requiring postive and negative polarity protection. Low leakage allows these diodes 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 and SOT-323 (SC-70) packages are good for applications requiring automatic optical inspection (AOI).
