DMP2078LCA3-7

Overview

The DMP2078LCA3-7 is a P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a drain-source voltage (Vdss) of -20 V and a continuous drain current (Id) of -3.4 A at +25°C. The device offers a maximum on-resistance (Rds(on)) of 78 mΩ at Vgs = -8 V and 100 mΩ at Vgs = -4.5 V. It operates within a junction temperature range of -55°C to +150°C, with a power dissipation of 0.81 W in standard surface mount configurations.

Feature Summary

• Designed for minimal footprint in handheld and mobile applications
• Low gate charge (Qg) and gate-drain charge (Qgd)
• Low profile package height of 0.20 mm
• Totally lead-free and fully RoHS compliant

Applications

• Battery management systems
• Load switches
• Battery protection circuits
• Handheld devices
• Mobile applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The -7 suffix indicates an 8mm carrier tape width with a 2mm pitch packed in quantities of 10,000 units per reel. Confirm that the component meets all required environmental standards, including RoHS compliance and halogen-free specifications, before finalizing procurement orders.

Selection Notes

Select this component when space constraints are critical due to its small X4-DSN1006-3 package. Ensure the application requires a -20 V rating and can accommodate the specified thermal resistance values. Verify that the gate drive voltage aligns with the low Rds(on) performance thresholds provided in the datasheet electrical characteristics.
