Product details
Overview
DMPH33M8SPSW-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for -30V VDSS, 3.8mΩ RDS(ON) @ VGS = -10V, and -100A continuous drain current at TC = +25°C. It serves as a high-current, low-loss power switch in DC-DC converter synchronous rectification and battery protection circuits.
For engineers reviewing the DMPH33M8SPSW-13 datasheet, DMPH33M8SPSW-13 pinout, DMPH33M8SPSW-13 application, or DMPH33M8SPSW-13 equivalent, key selection criteria include its 1.1°C/W RθJC, -175°C to +175°C operating range, 241mJ EAS, and thermally optimized exposed-drain PowerDI5060-8 (SWP) package for high-power density designs.
Technical Context
This MOSFET employs trench-gate silicon process technology to achieve ultra-low on-resistance while maintaining robust switching performance. Its gate threshold voltage of -1V to -3V ensures reliable turn-on with standard logic-level gate drivers in high-side configurations.
The device integrates a fast-recovery body diode with tRR = 26.5ns and QRR = 37.3nC, enabling efficient operation in hard-switched topologies. Thermal design is supported by a 1.1°C/W junction-to-case resistance and validated 100% UIS testing up to -69A avalanche current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands up to 30V reverse drain-source voltage without breakdown in blocking state. |
| RDS(ON) | 3.8mΩ @ VGS = -10V - Enables <1.5W conduction loss at 60A, critical for high-efficiency power stages. |
| ID (continuous) | -100A @ TC = +25°C - Supports high-current load switching when mounted on adequate copper area. |
| RθJC | 1.1°C/W - Allows direct thermal path from junction to PCB copper, enabling compact heatsinking. |
| EAS | 241mJ - Rated avalanche energy supports robustness against inductive switching transients. |
| tRR | 26.5ns - Fast body diode recovery reduces switching losses and cross-conduction risk in synchronous buck converters. |
| Qg | 127nC - Gate charge level determines driver strength requirement and influences switching speed vs. EMI trade-off. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-current power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH3010LPSQ-13 | -30V VDSS, 4.2mΩ RDS(ON) @ -10V, same PowerDI5060-8 package, but rated only to +150°C. | Lacks AEC-Q101 qualification and 175°C rating; unsuitable for extended-temperature automotive modules. | Select when cost sensitivity outweighs extended temperature margin and avalanche robustness. |
| IPB80P03P4L-04 | -30V VDSS, 3.4mΩ RDS(ON) @ -10V, TO-263-7 package, higher RθJA (47°C/W). | Larger footprint and lower thermal efficiency require larger PCB area and heatsink for equivalent power handling. | Choose only if legacy TO-263 layout compatibility is mandatory and board space is not constrained. |

FAQ
What is the maximum allowable gate-source voltage for DMPH33M8SPSW-13?
The absolute maximum VGS rating is ±20V per the datasheet's Maximum Ratings table. Operation beyond ±20V risks permanent gate oxide damage. For reliable turn-on, -10V is recommended to achieve specified 3.8mΩ RDS(ON); -6V yields 10mΩ and is acceptable for reduced-current applications.
Can DMPH33M8SPSW-13 be used in parallel configurations?
Yes-its negative temperature coefficient of RDS(ON) (normalized resistance increases with temperature, per Figure 6) promotes inherent current sharing. However, matched gate drive layout, symmetrical PCB copper, and individual gate resistors are required to minimize dynamic imbalance during switching transitions.
Is DMPH33M8SPSW-13 qualified for automotive applications?
The part itself is not AEC-Q101 qualified per the datasheet note stating "for automotive applications requiring specific change control… please contact us." It is rated for -55°C to +175°C operation and 100% UIS tested, but formal PPAP documentation and IATF 16949 manufacturing evidence are not provided in DS43451 Rev. 3-2.
What is the recommended PCB pad layout for thermal performance?
Diodes specifies a minimum 1-inch square copper plate (2oz) for the exposed drain pad to achieve the 44°C/W RθJA rating. The datasheet references http://www.diodes.com/package-outlines.html for exact pad dimensions; typical layout uses 4.70–5.10mm D1 and 5.60–6.00mm E1 outlines with thermal vias under the pad to inner ground planes.
