FDT86256
N-Channel PowerTrench® MOSFET
150 V, 1.2 A, 845 mΩ
Features
General Description
„ Max rDS(on) = 845 mΩ at VGS = 10 V, ID = 1.2 A
This N-Channel MOSFET is produced using Fairchild
Semiconductor’s advanced PowerTrench® process that has
been especially tailored to minimize the on-state resistance and
switching loss. G-S zener has been added to enhance ESD
voltage level.
„ Max rDS(on) = 1280 mΩ at VGS = 6.0 V, ID = 1.0 A
„ Very low Qg and Qgd compared to competing trench
technologies
„ Fast switching speed
Applications
„ 100% UIL Tested
„ DC-DC conversion
„ RoHS Compliant
„ Inverter
„ Synchronous Rectifier

NOTES:
1. RθJA is determined with the device mounted on a 1 in2 pad 2 oz copper pad on a 1.5 x 1.5 in. board of FR-4 material. RθJC is guaranteed by design while RθCA is determined by
the user's board design.
a) 55 °C/W when mounted on a
1 in2 pad of 2 oz copper
b) 118 °C/W when mounted on
a minimum pad of 2 oz copper
2. Pulse Test: Pulse Width < 300 μs, Duty cycle < 2.0 %.
3. Starting TJ = 25 °C, L = 3 mH, IAS = 1 A, VDD = 150 V, VGS = 10 V.
4. The diode connected between gate and source serves only as protection against ESD. No gate overvoltage rating is implied.

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used here in:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance with
instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,
www.Fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
