New ESD5V0-Diode Series Increases ESD and Surge Robustness in High-Volume Applications

Block diagram

ESD5V0S1U-02V and ESD5V0L1B-02V, the new TVS protection devices from Infineon, significantly improve the reliability of electronic equipment and help to prevent serious field failures and warranty returns caused by ESD and transients resulting from routine use.

Flexible solution for a huge variety of applications:
ESD5V0S1U-02V and ESD5V0L1B-02V improve system-level reliability of various application segments, ensuring protection against positive and negative strikes. These new diodes are tailored to protect data and power lines with signals of up to ±5V and ensure protection against positive and negative strikes.
Battery-powered equipment greatly benefits from the extremely low reverse current of less than 1nA (typ. value, maximum 50nA at 3V), which results in very low power consumption in normal operating mode.

Great space saving compared with ceramic technology
ESD5V0S1U-02V and ESD5V0L1B-02V are available in single-line leaded SC79 (SOD 523) packages with 1.2x0.88x0.55mm body size. These devices are compliant with RoHS and halogen-related directives. The compact footprint makes them ideal replacements for 0603 varistors, enabling more than 25% space saving on the PCB board. In addition, they reduce the package height of 0603 varistors by between 20% and 40%.

Availability
These devices have been in volume production since January 2011. For application information, see AN248 "Tailored ESD Protection for Various Electronic Interfaces" at www.infineon.com/tvsdiodes.

Features

Applications

High ESD absorption capability exceeding most stringent IEC61000-4-2 industry standard
- up to ±20kV for ESD5V0S1U-02V
- or ±25kV for ESD5V0L1B-02V
Dissipation of Electro Fast Transients (EFT) according to IEC61000-4-4 (5/50ns)
- up to 50A (ESD5V0S1U-02V)
- or 40A (ESD5V0L1B-02V)
Surge protection capability up to 5.5A (ESD5V0S1U-02V) or 2.5A (ESD5V0L1B-02V) according to IEC61000-4-5 standard for an 8/20us pulse
Unlike lower quality varistor options, Infineon diodes show no degradation effects in the event of multiple strikes
Better protection through better trigger and clamping voltages compared with multi-layer varistors
Very fast response time (below 1ns) results in extremely low and stable clamping voltages
