ON Semiconductor Reveals Miniature MOSFETs


The new devices are optimised for interface and power management applications in ultra portable consumer electronics


ON Semiconductor has introduced a pair of ultra small, ultra thin, small signal MOSFETs.

They are optimised for space-constrained portable consumer electronics such as tablet computers, smart phones, GPS systems, digital media players and portable games consoles.

"As portable electronics continue to decrease in size while the number of on-board features continue to increase, there is, and will continue to be, an ongoing need for ultra small, high performance components to make feature-rich on-the-go devices energy efficient and highly functioning," says Paul Leonard, vice president of ON Semiconductor's MOSFET products division.

"The NTNS3193NZ and NTNS3A91PZ do just this by enabling design engineers to specify a device that has the necessary features and functionality while still allowing sleek, stylish designs that consumers have now come to expect," he continues.

ON Semiconductor says the NTNS3193NZ and NTNS3A91PZ are the industry's most compact small-signal MOSFETs as they are housed in a tiny 0.62 mm x 0.62 mm x 0.4 mm XLLGA3 package.

With a total surface mount area of only 0.38 mm², the XLLGA3 package is the ideal solution for the ever shrinking environments of portable electronics, and easily replaces competitive products offered in much bigger packages such as SOT-883 (with a surface mount area of 0.6mm²) or the SOT-723 (with mount area of 1.44mm²).

The NTNS3193NZ is a 20V, single N-channel, 0.75 Ω typical on resistance at ±4.5 voltage gate to source (VGS) device. This is complemented by the NTNS3A91PZ -20 V, single P−channel device, which has 1.3Ω typical on resistance at ±4.5V.

With low RDS(on), low threshold voltage, and 1.5 V gate drive capability, these new MOSFETs greatly reduce power consumption when incorporated in portable electronic products making both devices ideally suited for small signal load switches, analogue switches and high speed interfacing. Both devices are fully lead-free, halogen-free and are RoHS compliant.

The NTNS3193NZ and NTNS3A91PZ are priced at $0.33 and $0.35 per unit in 8,000 quantities respectively.
