TVS Diode for FM Radio Antenna Systems

The ESD5V3L1U-02LRH is our new diode designed for the ESD protection of electronic devices incorporating FM radio antenna systems. Placed behind the antenna, this diode can absorb ESD discharges of up to ±30kV (IEC61000-4-2 contact discharge) and thus protect ICs downstream of the RF-in port. Available in a 0402 EIA–equivalent package, this device is ideal for space-constrained applications as the small form factor means it can be easily integrated in front of the LNA.

Flanking the ESD0P2RF diode series, the new diode complements our antenna protection offering. The ESD5V3L1U-02LRH is the solution of choice for providing very low dynamic resistance/low clamping voltage in FM radio systems beyond the GSM environment. In the case of hostile interfering environments, the bidirectional ESD0P2RF series (already in mass production) is the preferred ESD solution.
