HAZ1045-04SU

HXY MOSFET · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

HAZ1045-04SU from HXY MOSFET, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I/O1 passive ESD-protected signal I/O channel 1. Clamped by a pair of steering diodes to the internal positive and GND rails; VRWM=5 V, VBR=6 V min, positive clamping voltage 12 V max at IPP=4 A (8/20 µs). Low junction capacitance (~0.6 pF typ to GND, 0.3 pF typ channel-to-channel).
2 GND power_in Negative rail / system ground reference. The datasheet states 'the negative rail pin (assigned as GND) is connected with system ground.' All ESD clamping is referenced from I/O pins to this node.
3 I/O2 passive ESD-protected signal I/O channel 2. Same clamping structure and parameters as I/O1.
4 I/O3 passive ESD-protected signal I/O channel 3. Same clamping structure and parameters as I/O1.
5 I/O4 passive ESD-protected signal I/O channel 4. Same clamping structure and parameters as I/O1.
6 I/O5 passive ESD-protected signal I/O channel 5. Same clamping structure and parameters as I/O1.
