ESD and Surge Protection

System level ESD protection becomes more important and more difficult with each new generation of electronics. New and emerging applications require ever more capable protection solutions. Infineon leads with a strong and growing family of ESD protection devices with better clamping, lower capacitance, and an a wide range of operating voltages.

On top of this, Infineon’s Chip Scale Package (CSP) focus supports both high quality levels and high production volume support at extremely competitive pricing.

ESD and Surge Protection subcategories

Multi purpose diodes for ESD protection

When your application requires ESD protection and there is no concern for high speed signal integrity or RF signal degradation, then multi purpose protection is what you need. You need strong protection that fits your application.

Infineon leads the way for –

• small packaging to support minimum board space consumption and optimal placement
• Outstanding clamping performance – allowing you to spend less time worrying about ESD events and more focusing on your system differentiation
• High linearity – reducing harmonic generation / intermodulation distortion for protected lines near strong RF signals in your system… enabling suppression EMC problems
• Exceptional quality, reliability, and volume support – so that when your design is done, it really is done

Highlights

Outstanding clamping options for general application

• ESD241-B1-W0201
• ESD242-B1-W01005
• ESD245-B1-W0201
• ESD246-B1-W01005
• ESD231-B1-W0201

Tailored devices for best linearity performance

• ESD249-B1-W0201
• ESD259-B1-W0201

Low capacitance diodes for ESD protection

Now you need to protect a high speed I/O or an RF signal. Lower and lower capacitance protection with good clamping performance is necessary. In an increasing number of applications very low harmonic generation is needed.

Infineon has the answer for –

• Low capacitance – freeing some room in your link budget / maximizing signal integrity
• While still providing strong ESD protection
• High Linearity – reducing harmonic generation / intermodulation distortion for protected lines near strong RF signals in your system… enabling suppression EMC problems
• Exceptional quality, reliability, and volume support – so that when your design is done, it really is done
• small packaging to support minimum board space consumption and optimal placement
