PESD1LIN

LIN bus ESD protection diode in SOD323

Rev. 01 — 26 October 2004 Product data sheet

1. Product profile

1.1 General description

PESD1LIN in very small SOD323 (SC-76) SMD plastic package designed to protect one
automotive LIN bus line from the damage caused by ElectroStatic Discharge (ESD) and
other transients.

1.2 Features

■ ESD protection of one automotive LIN bus line

■ Asymmetrical diode configurationensuresanoptimized Electromagnetical Immunity of

a LIN Electronic Control Unit (ECU)

■ Due to the integrated diode structure only one very small SOD323 package is needed

■ Max. peak pulse power: PPP = 160 W at tp = 8/20 µs

■ Low clamping voltage: V

■ Ultra low leakage current: IRM < 1 nA

■ ESD protection of up to 23 kV

■ IEC 61000-4-2, level 4 (ESD)

■ IEC 61000-4-5 (surge); IPP = 3 A at tp = 8/20 µs

= 40 V at IPP = 1 A

(CL)R

1.3 Applications

■ LIN bus protection

■ Automotive applications
