Features of PESD1

Compact SOT323 Package

PESD1 is designed in a very small SOT323 package, making it ideal for applications where space is limited. This compact design allows you to integrate it seamlessly into tight circuit layouts, especially in automotive and industrial environments.

Low Clamping Voltage

The diode features a low clamping voltage of 35 V at an IPP of 1A. This ensures that your circuits remain protected by reducing the impact of voltage surges, safeguarding sensitive components effectively.

Consistent Capacitance Matching

PESD1 offers typical diode capacitance matching of ΔCd/Cd = 0.1%. This precise matching helps maintain stable circuit performance, making it reliable for systems that demand accuracy and consistency.

High-Level ESD Protection

With protection against electrostatic discharge (ESD) up to 23 kV, PESD1 meets IEC 61000-4-2, level 4 standards. This feature ensures robust safeguarding against static discharge, even in harsh environments.

Surge Current Handling

PESD1 can manage surge currents up to 3 A with an 8/20 µs waveform, compliant with IEC 61000-4-5 standards. This capability makes it a dependable solution for protecting circuits from sudden high-current surges.

Automotive-Grade Certification

The diode is AEC-Q101 qualified, meaning it meets stringent automotive industry standards. This certification ensures that PESD1 delivers reliable performance even under demanding automotive conditions.
