7 Detailed Description

7.1 Overview

The ESD1LIN24-Q1, ESD751-Q1, and ESD761-Q1 are single-channel ESD diodes available in industry

standard packages (SOD-323 and SOD-523) which are convenient for automatic optical inspection as well as

a smaller leadless package X1SON (DPY). These products offer ISO 10605 ESD ratings of (±30- kV Contact,

±30-kV Airgap), (±22-kV Contact, ±22- kV Airgap), and (±15-kV Contact, ±15-kV Airgap), respectively. The 2.3

pF, 1.6 pF, and 1.1 pF line capacitance of these ESD protection diodes are suitable for LIN applications that

support data rates from 20 Kbps to 10 Mbps.

Typical application of these products is the ESD circuit protection for LIN transceivers used in automotive

applications. These devices are commonly used for ESD protection inside automotive electronic control units

(ECUs) for head lights, door modules, climate control, roof control, wipers, cluster, audio, and many other

automotive applications.

7.3 Feature Description

The ESD1LIN24-Q1, ESD751-Q1, and ESD761-Q1 are single-channel bidirectional ESD diodes with a high

ESD protection level. These devices have a small dynamic resistance, which makes the clamping voltage low

when the device is actively protecting other circuits. The breakdown is bidirectional so these protection devices

can prevent system damage if battery leads are swapped. Low leakage allows the diodes to conserve power

when working below the VRWM. The temperature range of −55°C to +150°C makes these ESD devices work at

extensive temperatures in most environments.

7.3.1 IEC 61000-4-5 Surge Protection

The I/O pins of the ESD1LIN24-Q1, ESD751-Q1, ESD761-Q1 have the following surge ratings (8/20 µs

waveform): 4.3A, 2.8 A, and 1.8 A, respectively. An ESD-surge clamp diverts this current to ground.

7.3.2 IO Capacitance

The capacitance between the I/O pins of the ESD1LIN24-Q1, ESD751-Q1, and ESD761-Q1 devices are as

follows: 2.3 pF, 1.6 pF, and 1.1 pF, respectively. The capacitance of these devices support data rates for LIN up

to 10 Mbps.
