Zetex Semiconductors Releases Two MOSFETs in New ZXMN Series
Zetex Semiconductors (Commack, NY) has introduced the first two devices from their projected range of new-generation n-channel MOSFETs, the ZXMN3AO1F and the ZXMN3A02X8.
The ZXMN3AO1F is SOT-23-packaged and rated at 30V. Its continuous drain current is 2.05A, afforded by an on-resistance of 90mohms for a Vgs of 10V, and 145mohms for a Vgs of 4.5V. A gate charge of 2.3nC ensures low switching loss and high efficiency in high-frequency, low-voltage switching applications.
For increased current capability, the ZXMN3A02X8 is rated at 30V, with a continuous current rating of 6.7A, allowed by an on-resistance of 18mohms for a Vgs of 10V. This device has a Vgs of 4.5V with 25mohms. The gate charge is 14.5nC.
Both package variants feature a low gate-threshold charge and a low gate-charge requirement. They are suitable for use in low-voltage dc/dc conversion, dc motor drives, power management and load-interface functions.
In quantities of 1,000 pieces, the ZXMN3AO1F is priced at $0.16 each, and the ZXMN3A02X8 at $0.64 each. Both are quoted with a four- to six-week delivery for production volumes.
