ESD Protection Diodes L30ESDL5V0C3-1

Dual ESD Protection Diodes

  • Stand-Off Voltage - 5 Volts
  • Power Dissipation - 300 Watts

General Description

The L30ESDL5V0C3-1 is a dual voltage suppressor designed to protect components which are connected to data and transmission lines against Electro Static Discharge (ESD).

It clamps the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients.

It can work as bidirectional suppressor by connecting only pin 1 to 2.

Features

  • 1 Unidirectional ESD protection
  • Max. peak pulse power: Ppp = 300W at tp = 8/20 µs
  • Ultra low leakage current: IRM < 1µA @ VBR
  • ESD protection > 25KV per MIL-STD-883C, Method 3015-6: Class 3
  • IEC 61000-4-2, level 4 (ESD), >15KV (air); >8KV (contact)
  • Ultra small SMD plastic packages

Application

  • Computers and peripherals
  • Communication system
  • Portable electronics
  • Cellular handsets and accessories

Mechanical Data

  • Case Material: “Green” molding compound UL flammability classification 94V-0 (No Br.Sb, Cl)
  • Terminals: Lead Free Plating (Matte Tin Finish)
  • Component in accordance to RoHs 2002/95/EC

Application Information

Low capacitance protection of one high-speed line: Protection of one unidirectional or bidirectional high-speed line is achieved by connecting two devices in anti-parallel. Pin 1 of the first device is connected to the line and pin 2 is connected to ground (or to a second line for differential protection). Pin 2 of the second device is connected to line 1 and pin 1 is connected to ground (or line 2) as shown. Pin 3 is not connected.
