Infineon Launches ESD Protection Diodes Suitable for Low-Voltage Applications
Published2012.08.16 15:56August 16, 2012, Seoul - Infineon Technologies (Korea CEO Lee Seung-su) has launched a series of TVS (Transient Voltage Suppression) diodes that enhance robustness against ESD (electrostatic discharge), which can damage consumer electronics. The new 3.3V bidirectional diodes exhibit the industry's best clamping voltage and ESD absorption capability, protecting systems from electrical spikes in audio input stages and touch screen interface circuits.
TVS diodes prevent damage by grounding unexpected ESD before it can damage sensitive system components. Key performance characteristics required for this include fast response time, fast recovery time to prevent simultaneous ESD events, and excellent durability.
Infineon Technologies' bidirectional ESD3V3S1-B series not only meets all these requirements but also provides specifications that meet and exceed industry standards as follows:
- Fast turn-on time and extremely low dynamic resistance of only 0.13Ohm provide very low clamping voltage, protecting low-power circuits used in audio interface and touch screen display applications.
- Excellent ESD absorption capability rated at 30kV (contact discharge) exceeds the IEC61000-4-2 industry standard benchmark of 8kV. When tested under extreme transient conditions (90A transmission line pulse, equivalent to the 48kV IEC61000-4-2 standard), these diode products exhibited no performance degradation.
- Available in EIA0201-compatible (0.62mm x 0.32mm x 0.31mm, TSSLP-2) and EIA0402-compatible (1.0mm x 0.6mm x 0.39mm, TSLP-2) packaging, allowing use in various types of applications.
Availability
ESD3V3S1B samples and evaluation boards are currently available. TSSLP-2 and TSLP-2 packages are fully compliant with RoHS and halogen-free regulations.
To enhance ESD system robustness and enable rapid design, Infineon provides a comprehensive simulation model library for TVS diodes, and also offers professional support services to select appropriate protection devices.
