Overview
The DMTH42M5LPSW-13 is an N-Channel Enhancement Mode MOSFET manufactured by Diodes Incorporated. It features a drain-source voltage (BVDSS) of 40V and is housed in a PowerDI5060-8 surface-mount package with wettable flank technology. The device supports a continuous drain current of 142A at case temperature and offers thermal performance of 3.72W at ambient temperature and 89.8W at case temperature.
Feature Summary
- Utilizes wettable flank technology to enhance solder joint inspection reliability and mechanical connection integrity.
- Designed for high-current applications with a 40V breakdown voltage rating.
- Optimized thermal dissipation capabilities within the compact PowerDI5060-8 footprint.
Applications
- High-efficiency DC-DC converter circuits
- Power management modules requiring low on-resistance
- Automotive electronics systems
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required wettable flank variant. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet. Validate pinout compatibility during PCB layout integration to prevent assembly errors.
Selection Notes
Select this component when high current handling and reliable solderability are critical. The 40V rating suits low-voltage power stages. Consider the thermal resistance values for heat sink requirements. Compare against standard packages if wettable flank inspection is not mandated by quality standards.
Part Context
This part belongs to Diodes Incorporated's PowerDI series, focusing on robust surface-mount solutions. The DMTH prefix indicates a specific threshold voltage and Rds(on) characteristic within the 40V class. It complements other devices in the lineup offering similar voltage ratings but different current or thermal profiles.
Replacement Considerations
Direct substitutes must match the 40V BVDSS, PowerDI5060-8 package, and wettable flank specification. Verify equivalent Rds(on) and Qg parameters to maintain switching performance. Generic PowerDI replacements without wettable flanks may fail automated optical inspection requirements.
