ESDA14V2-1BF3

Single-line bidirectional Transil™ array for ESD protection

Features

■ ESD Protection: IEC61000-4-2 level 4

■ Low leakage current

■ Very small PCB area < 0.4 mm²

■ 400 micron pitch

Complies with the following standards

■ IEC61000-4-2 level 4

– 15 kV (air discharge)

– 8 kV (contact discharge)

Applications

Where transient overvoltage protection of ESD

sensitive equipment is required, such as:

■ Computers

■ Printers

■ Communications systems and cellular phones

■ Video equipment

Description

The ESDA14V2-1BF3 is a monolithic bidirectional

diode designed to protect 1 line against ESD

transients.

The device is ideally suited for applications where

both reduced line capacitance and board space

saving are required.

ESDA14V2-1BF3 4.2 PCB recommendations Assembly For chip scale package mounting on the PCB, STMicroelectronics recommends the use of a solder stencil aperture of 330 x 330 µm² maximum and a typical stencil thickness of 75 or 80 µm. Chip scale packages are fully compatible with the use of near eutectic 95.5 Sn, 4 Ag, 0.5 Cu solder paste with no-clean flux. ST's recommendations for chip scale package board mounting are illustrated on the soldering reflow profile shown in Figure 15. Figure 15.
