ESD103-B1-02ELS

The Infineon ESD103-B1-02ELS is a bi-directional ESD protection device featuring a symmetric I/V characteristic and excellent clamping performance. It is specifically designed for applications requiring extremely low capacitance and high linearity, such as RF antennas and interfaces including LTE and WLAN.

Key electrical specifications include a bi-directional maximum working voltage of ±15 V and a typical line capacitance of 0.09 pF at 1 GHz. The device provides robust ESD and transient protection according to IEC61000-4-2 standards, withstanding ±14 kV in air and ±10 kV on contact. Its clamping voltage is typically 48 V at 16 A, with a dynamic resistance of 1.8 Ω. The leakage current is very low, at 0.1 nA.

This ESD protection device comes in a small form factor SMD package with dimensions of 0.62 x 0.32 x 0.31 mm³. It is qualified for industrial applications according to JEDEC standards. The TSSLP-2-4 package is suitable for surface mount applications and is supplied on reels of 15,000 pieces.

Potential applications include protecting RF antennas and interfaces in mobile devices, LTE, and WLAN systems. The device's low capacitance makes it ideal for high-frequency signal lines where minimal signal distortion is critical.
