حفاظت مدار محدودکننده‌های ولتاژ گذرا (تی وی اس) تریستور محافظ اضافه‌ولتاژ (تی اس اس)

Product Attributes

Introduction

The PEP01-5841 has been designed to protect power over Ethernet PSE equipment against line overvoltages. It embeds 4 decoupling capacitors to stabilize power supplies. It is compatible with IEEE 802.3af-2003 and IEEE 802.3at-2008 requirements and it allows PoE based systems to be protected against both electrical overstress (EOS) and electrostatic discharges (ESD) according to IEC61000-4-5 and IEC61000-4-2. The low clamping voltage (100 V) makes it compatible with PMOS and PSE controller technologies. Developed in Planar technology, it provides high reliability level. Packaged in SO-8, it minimizes PCB consumption (footprint in accordance with the IPC 7531 standard).
