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

Product Attributes

Introduction

These devices are ideally suited to meet the protection requirement of VoIP SLICs located in next generation residential gateways. They can be used for protecting any ringing SLIC since they meet the protection standard requirements. Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -V_{BAT} through the gate. These components present a very low gate triggering current (I_{GT}) to reduce the current consumption on printed circuit board during the firing phase.

Features

• Dual programmable transient suppressor
• Wide negative firing voltage range: V_{Gn} = -175V max.
• Low dynamic switching voltages: V_{FP} and V_{DGL}
• Low gate triggering current: I_{GT} = 5 mA max
• Peak pulse current: I_{PP} = 37.5 A (5/310 μs)
• Holding current: I_{H} = 150 mA min.
• Low space consuming package

Applications

• fiber in the loop
• WLL
• remote central office
