Product details
Overview
HAT1044M-EL-E from Renesas Electronics is a silicon P-channel power MOSFET designed for low-voltage DC power switching in compact consumer and industrial electronics. It features –30 V drain-to-source voltage, 105 mΩ RDS(on) at –4.5 V gate drive, –4.5 A continuous drain current, and TSOP-6 surface-mount packaging - enabling efficient load switching in battery-powered USB peripherals and portable device power rails.
For engineers reviewing the HAT1044M-EL-E datasheet, HAT1044M-EL-E pinout, HAT1044M-EL-E application, or HAT1044M-EL-E equivalent, key selection criteria include verified –4.5 V logic-level gate compatibility, body-diode forward voltage (–0.95 V), thermal derating on alumina ceramic board, and pulse-rated drain current (–18 A) for inrush handling.
Technical Context
This P-channel MOSFET operates as a high-side load switch with gate threshold voltage ranging from –1.0 V to –2.5 V, ensuring reliable turn-on with standard 5 V microcontroller outputs. Its low input capacitance (600 pF) and fast switching times (td(on) = 12 ns, tf = 55 ns) support efficient PWM control up to several hundred kHz in DC-DC post-regulation and LED driver circuits.
The device integrates a body-drain diode with 50 ns reverse recovery time and –0.95 V forward voltage at –4.5 A, making it suitable for synchronous rectification replacement and flyback catch diode applications where low conduction loss is critical under constrained board space.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2305DS-T1-E3 (Vishay) | –20 V VDSS, 115 mΩ RDS(on) @ –4.5 V, same TSOP-6 package | Limited to ≤20 V systems; higher on-resistance increases conduction loss by ~15% | Select when lower voltage rating suffices and second-source qualification is required |
| AO3401 (Alpha & Omega) | –30 V VDSS, 85 mΩ RDS(on) @ –4.5 V, same pinout but slightly higher Qg (17 nC) | Marginally slower switching due to higher gate charge; identical thermal profile | Prefer for higher current density designs where 85 mΩ improves efficiency over 105 mΩ |
Compared with Si2305DS-T1-E3 and AO3401, the HAT1044M-EL-E offers the lowest gate charge (13 nC) among TSOP-6 P-channel devices rated for –30 V, enabling tighter PWM timing control and reduced gate driver power consumption in space-constrained applications.

FAQ
What is the maximum continuous drain current rating for the HAT1044M-EL-E?
The HAT1044M-EL-E has a continuous drain current (ID) rating of –4.5 A when mounted on a 50 × 50 × 0.7 mm alumina ceramic board at Ta = 25°C. This rating assumes proper PCB thermal design; derating is required above 25°C ambient or with smaller copper areas. The HAT1044M-EL-E must not exceed its 1.05 W continuous channel dissipation limit under sustained load conditions.
Does the HAT1044M-EL-E support 3.3 V logic-level gate drive?
Yes - the HAT1044M-EL-E is specified to fully enhance at VGS = –4.5 V, and its gate threshold voltage range (–1.0 V to –2.5 V) ensures reliable turn-on with 3.3 V or 5 V microcontroller outputs. While not guaranteed at exactly –3.3 V, typical RDS(on) remains below 200 mΩ at –3.3 V per characterization data, making the HAT1044M-EL-E suitable for direct GPIO drive in most 3.3 V systems.
What is the thermal resistance (RθJA) of the HAT1044M-EL-E in its TSOP-6 package?
Renesas does not publish a standalone RθJA value for the HAT1044M-EL-E; instead, thermal performance is defined via channel dissipation limits: 1.05 W continuous and 2.0 W pulsed on a 50 × 50 × 0.7 mm alumina ceramic board. This corresponds to an effective RθJA ≈ 95°C/W under those specific board conditions. For FR-4 PCBs, users must perform layout-specific thermal simulation or measurement - the HAT1044M-EL-E's exposed drain terminals require generous copper pour for acceptable junction temperature rise.
Can the HAT1044M-EL-E be used as a synchronous rectifier?
Yes - the HAT1044M-EL-E is suitable as a synchronous rectifier in low-voltage DC-DC converters due to its low RDS(on) (105 mΩ @ –4.5 V), fast switching (td(off) = 55 ns), and integrated body diode with 50 ns reverse recovery time and –0.95 V forward voltage. When used in this role, the HAT1044M-EL-E replaces a Schottky diode to reduce conduction loss, especially in buck or flyback topologies operating below 12 V output.
Is the HAT1044M-EL-E RoHS-compliant and lead-free?
Yes - the HAT1044M-EL-E is manufactured in accordance with the EU RoHS Directive and is lead-free. Its TSOP-6 package (RENESAS code PTSP0006FA-A) uses lead-free terminations and complies with JEDEC standards for moisture sensitivity level (MSL) 1. The "-E" suffix in the part number explicitly denotes RoHS-compliant packaging, and Renesas confirms full environmental compliance documentation is available upon request.
