ESDAXLC18-1BF4 Description

Short technical summary and product information.

The ESDAXLC18-1BF4 is a bidirectional TVS diode manufactured by STMicroelectronics, designed for general purpose ESD protection. It features a reverse standoff voltage of 18V and a maximum clamping voltage of 20V, providing robust protection for sensitive electronic circuits.

 

With a peak pulse power dissipation of 50W and a peak pulse current rating of 2.2A (8/20 µs waveform), this device is suitable for protecting data lines and I/O ports from electrostatic discharge and transient overvoltage events. The typical capacitance is 1.6 pF at 1 MHz, making it appropriate for high-speed signal lines.

 

The device is housed in a compact 0201 (0603 Metric) surface mount package, ideal for space-constrained designs. It operates over a junction temperature range of -40°C to 150°C and is RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity.
