Device Structure

Metal Oxide Semiconductor Field Effect Transistor (MOSFET)

Dual P-Channel configuration integrated in one package

PowerTrench® planar process technology providing low on-resistance and improved switching efficiency

Designed in a small, low-profile WDFN surface-mount package with an exposed thermal pad for efficient heat dissipation

Performance Characteristics

Low Rds(on) at logic-level gate voltages ensures lower power loss and better efficiency in switching circuits

Fast switching enabled by low gate charge (10 nC max) reduces switching power dissipation

Stable gate threshold voltage suitable for low voltage control circuitry

Wide operating temperature range (-55°C to 150°C) making it reliable in various thermal environments

Compact footprint and low profile ideal for dense PCB layouts and portable devices

Application Environments

Power management circuits in portable and battery-operated devices

DC-DC converters, load switching, and power rail control

High-efficiency power switching in communication equipment

Low voltage motor driver circuits

Battery protection and power distribution in consumer electronics

Automotive electronics where compact size and temperature tolerance are required

Selection Guidelines

Choose FDMA1029PZ when low voltage (20V max) P-channel MOSFETs with moderate continuous current (up to 3.1A) are needed

Suitable for applications requiring dual MOSFETs combined in a compact package to save board space

Evaluate Rds(on) and gate charge values for efficiency targets in switching applications

Confirm package type (6-WDFN 2x2 mm) fits mechanical and thermal requirements for the design

Verify maximum power dissipation and operating temperature range support environmental demands

Usage Considerations

Ensure gate drive voltage is sufficient to fully turn on the device (logic level gate suitable for ~4.5V)

Use proper PCB layout with thermal pad soldered to a thermal plane to maximize heat dissipation

Protect from ESD and handle moisture sensitivity level 1 devices per standard procedures

Avoid voltage or current exceeding the absolute maximum ratings to prevent device damage

Consider thermal derating at elevated temperatures to maintain reliability
