PESD1FLEX

FlexRay bus ESD protection diode

7 November 2021

Product data sheet

1. General description

PESD1FLEX in a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic package

designed to protect two automotive FlexRay bus lines from the damage caused by ElectroStatic

Discharge (ESD) and other transients.

2. Features and benefits

• Due to the integrated diode structure only one small SOT23 package is needed to protect two

FlexRay bus lines

• Max. peak pulse power: PPPM = 200 W at tp = 8/20 µs

• Low clamping voltage: VCL = 40 V at IPP = 1 A

• Ultra low leakage current: IRM = 1 nA

• Typ. diode capacitance matching: ΔCd/Cd = 0.1 %

• ESD protection up to 23 kV

• IEC 61000-4-2, level 4 (ESD)

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

• Small SMD plastic package

• AEC-Q101 qualified

3. Applications

• FlexRay bus protection

• Automotive applications
