حفاظت مدار محدودکننده‌های ولتاژ گذرا (تی وی اس) دیودهای تی وی اس

Product Attributes

Introduction

The PSM712 protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. They feature large cross-sectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, low operating voltage. It gives designer the flexibility to protect one bi-directional line in applications where arrays are not practical.

Features

• 400W peak pulse power per line (tP = 8/20μs)
• SOT - 23 package
• Bidirectional configurations
• Protects one power or I/O port
• ESD protection > 15 kV
• Low clamping voltage
• RoHS compliant
• Transient protection for data lines to IEC 61000 - 4 - 2(ESD) ±15KV(air), ±8KV(contact); IEC 61000 - 4 - 4 (EFT) 40A (5/50ns)

Applications

• RS - 485
• Security systems
• Automatic teller machines
• HFC systems
