Description
The CPC3909 is an N-channel, depletion mode Field
Effect Transistor (FET) that is available in an
SOT-223 package (CPC3909Z) and an SOT-89
package (CPC3909C). Both utilize IXYS Integrated
Circuits Division’s proprietary vertical DMOS process
that realizes world class, high voltage MOSFET
performance in an economical silicon gate process.
The vertical DMOS process yields a highly reliable
device, particularly for use in difficult application
environments such as telecommunications, security,
and power supplies.

Features
• 400V Drain-to-Source Voltage
• Depletion Mode Device Offers Low RDS(on)
at Cold Temperatures
CPC3909Z and the CPC3909C have a typical
on-resistance of 4.5 and a drain-to-source voltage
of 400V. As with all MOS devices, the FET structure
prevents thermal runaway and thermally induced
secondary breakdown.
• Low On-Resistance: 4.5 (Typical) @ 25°C
• Low VGS(off) Voltage
• High Input Impedance
• Low Input and Output Leakage
• Small Package Size SOT-89 and SOT-223
• PC Card (PCMCIA) Compatible
• PCB Space and Cost Savings
