ESD852, ESD862

SLVSH15 – NOVEMBER 2023

ESD8x2 2-Channel, 36 V ESD Protection Diode

1 Features

3 Description

•

Working voltage 36 V

Low leakage current 50 nA (maximum)

IEC 61000-4-2 ESD protection:

– ±25-kV contact and ±25-kV air (ESD852)

– ±18-kV contact and ±18-kV air (ESD862)

Robust surge protection:

– IEC 61000-4-5 (8/20 µs): 4.3 A (ESD852)

– IEC 61000-4-5 (8/20 µs): 3.1 A (ESD862)

Bidirectional ESD protection

I/O capacitance = 2.8 pF typical (ESD852)

I/O capacitance = 2.6 pF typical (ESD862)

SOT-23 (DBZ) small, standard, common footprint

Leaded packages used for automatic optical

inspection (AOI)

The ESD8x2 devices are bidirectional ESD protection

diodes for USB power delivery (USB-PD) and

industrial interfaces. The devices are rated to

dissipate ESD that meets or exceeds the maximum

level specified in the IEC 61000-4-2 standard (±25-kV

contact and airgap, or ±18-kV contact and airgap).

The low dynamic resistance and low clamping voltage

enables system level protection against transient

events. This protection is key because industrial

systems require a high level of robustness and

reliability.

•

These devices feature a low IO capacitance per

channel and a pin-out to suit two IO lines from

damage caused by electrostatic discharge (ESD) and

other transients. The I_PP= 4.3A (8/20 µs surge

waveform) capability of the ESD852 makes it an

excellent choice for protecting USB VBUS against

transient surge events as well as industrial I/O lines.

Additionally, the 2.8 pF or 2.6 pF line capacitance of

the ESD8x2 are an excellent choice for protecting the

slower speed signals for USB power delivery and IO

signals for industrial applications.
