RCLAMP0544M

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · MSOP-10

RCLAMP0544M from TECH PUBLIC, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Line 1 passive Data line 1 protected I/O pin (steering diodes to Vcc and GND), 0.3pF IO-to-IO typical, 5V working voltage, pin 1 indicator end.
2 Line 2 passive Data line 2 protected I/O pin, rated 5V reverse working voltage maximum, ±25kV air / ±20kV contact ESD per IEC 61000-4-2.
3 GND power_in Ground reference for the TVS array, common return for all line steering diodes (Pin 3 in schematic).
4 Line 3 passive Data line 3 protected I/O pin, clamping voltage 14V max at 1A and 20V max at 5A (8x20µs).
5 Line 4 passive Data line 4 protected I/O pin, peak pulse current 5A (8/20µs) rating.
6 NC unconnected No connect, bottom right pin opposite Line 4.
7 NC unconnected No connect.
8 Vcc power_in Power line connection protected by the array, joined to the common cathode of the steering diodes and the zener TVS (Pin 8 in schematic); 5V working voltage.
9 NC unconnected No connect.
10 NC unconnected No connect, top right pin opposite Line 1.
