STMicroelectronics' new n-channel MOSFET is designed for use in HID lamps, high-end ballasts and switch-mode power supplies that use zero-voltage and zero-current transitions.

The STx9NK60ZD MOSFET is touted to be the first device built using a new high-voltage process technology known as SuperFREDMesh. Due to this technology that realizes a new carrier lifetime control process on the company's basic High Voltage SuperMESH series, the device shows, along with exceptional dynamic performance, optimized body diode reverse-recovery time (trr) and very soft recovery. All these features help reduce switching losses, STMicro said.

Products built using the SuperFREDMesh technology are also said to benefit from reduced on-resistance, Zener gate protection, high dv/dt capability and cost competitiveness.

The product handles 600V, a drain current of up to 7A and offers a typical RDS(on) of 0.85 ohm. The STF9NK60ZD handles up to 30W, while the STB9NK60ZD and STP9NK60ZD each handle up to 125W.

Priced at 80 cents each in 100,000-unit orders, the MOSFETs are 100 percent avalanche tested and are available in TO-220, TO-220FP and D2PAK packages. Additional information can be found online.
