CM1241-04D4 Description

Short technical summary and product information.

The CM1241-04D4 is a 4-channel low capacitance dual-voltage ESD protection array designed by On Semiconductor. It offers ESD protection to IEC 61000-4-2 Level 4, with ±8 kV contact discharge on pins 1-3 and ±15 kV on pin 4. The device features a breakdown voltage range of 6.8V to 9.2V (at 10mA, 25°C) and a typical clamping voltage of 9.64V. It can handle peak pulse currents of 1A (8/20µs).

 

The array integrates three low-voltage ESD channels and one high-voltage channel, making it suitable for protecting multiple data lines and power rails in portable electronics. It requires no external bypass capacitors and exhibits minimal capacitance change with temperature and voltage.

 

The CM1241-04D4 is housed in an 8-WFDFN exposed pad package (8-WDFN 1.7x1.35) and is surface mountable. It is Pb-Free and RoHS compliant, supplied in tape and reel packaging with a standard quantity of 3000 pieces per reel.
