Dust-sized diode protects car antennas
With the rapid proliferation of wireless communications in automobiles, the number of antennas needing robust ESD protection has increased. This new single-line Transient Voltage Suppression (TVS) device that combines low-clamping ESD protection with an ultra-low capacitance rating can help in safeguarding car antennas against the harsh electrical transient threats present in vehicles.
With the rapid proliferation of wireless communications in automobiles, the number of antennas needing robust ESD protection has increased. The RClamp2431TQ, a single-line Transient Voltage Suppression (TVS) device from Semtech that combines low-clamping ESD protection with an ultra-low capacitance rating, can help in safeguarding car antennas against the harsh electrical transient threats present in vehicles.
The ultra-low capacitance of only 0.35pF line-to-line allows the device to be used on Wi-Fi, RFID, and other circuits operating in excess of 3GHz without signal attenuation. The device protects one high-speed line operating up to 24 volts and may be used to meet the ESD immunity requirements of IEC 61000-4-2. Compared to existing standard polymer devices, the RClamp2431TQ achieves as much as 40% reduction in ESD peak clamping voltage.
Housed in a 2-pin SLP1006P2T dust-size package measuring 1.0 x 0.6 x 0.4mm, the diode is qualified to AEC-Q100 Grade1 for use in Automotive...
