ESD8x2 2-Channel, 36V ESD Protection Diode - Features - Specifications

Nov 1, 2026

Uploaded by Aria

36V ESD8x2 is a bidirectional ESD protection diode series designed for USB power delivery (USB-PD) and industrial I/O interfaces. It supports IEC 61000-4-2 ESD protection levels up to ±25 kV (contact/air for ESD852 SOT-23), ±20 kV (ESD852 DFN1110-3), and ±18 kV (ESD862). It also provides IEC 61000-4-5 (8/20 µs) surge protection with peak currents up to 4.3 A. Low leakage current and low I/O capacitance per channel enable robust transient defense while preserving signal integrity.

ESD852, ESD862 SLVSH15B – NOVEMBER 2023 – REVISED JANUARY 2026 ESD8x2 2-Channel, 36V ESD Protection Diode 1 Features • Working voltage 36V • Low leakage current 50nA (maximum) • IEC 61000-4-2 ESD protection: – ±25kV contact, ±25kV air (ESD852 SOT-23) – ±20kV contact, ±20kV air (ESD852 DFN1110-3) – ±18kV contact, ±18kV air (ESD862) • IEC 61000-4-5 (8/20µs) Protection: – 4.3A (ESD852 SOT-23) – 3.8A (ESD852 DFN1110-3) – 3. 1A (ESD862) • Bidirectional ESD protection • Low I/O capacitance: – 2.8pF typical (ESD852 SOT-23) – 3.0pF typical (ESD852 DFN1110-3) – 2.6pF typical (ESD862) • Leaded packages used for automatic optical inspection (AOI) 2 Applications • Factory automation • Communication equipments • USB power delivery (USB-PD) : – VBUS protection – IO protection (withstand short to VBUS) • Industrial communications: – CAN / CAN-FD 3 Description 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 (±25kV contact and airgap, ±20kV contact and airgap, or ±18kV 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 IPP = 4.3A (8/20µs 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 2.8pF or 2.6pF 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.
