Designed for telecom, datacom or any –48-V bus applications, ON Semiconductor’s NUD3048 is a highly integrated N-Channel MOSFET featuring a breakdown voltage of 100 V and a buffered gate voltage rating of 100 V. This integrated MOSFET can function as a level shifter, a power good signal and an inrush limiter. It also can be used as a relay drive circuit.

To create this device, ON Semiconductor took an industry-standard 2N7002x, a small-signal 60-V MOSFET, and supercharged it into a 100-V N-Channel MOSFET. A gate-to-source Zener clamp, ESD protection diodes and 100-kΩ gate resistor have been integrated into the device—eliminating the need for many of the discrete components commonly required to support a 2N7002x MOSFET.

The NUD3048 is offered in a TSOP6 package, which saves board space while enabling external connections to both sides of the 100- kΩintegrated gate resistor. This feature permits a designer to add a gate capacitor to delay turn-on and still meet timing requirements. Additionally, the TSOP6 packaging—with its 0.72-Ω maximum on resistance—enables the device to handle approximately five times the continuous current of the industry standard 2N7002.

Pricing is $0.17 per unit in quantities of 10,000. Samples can be ordered online at www.onsemi.com. by searching the part number.
