Product details
Overview
IRF7509TR from Infineon Technologies (formerly International Rectifier) is a dual-channel complementary MOSFET in Micro8 package, integrating one 30 V N-channel and one −30 V P-channel HEXFET with RDS(on) of 0.06 Ω (N) and 0.14 Ω (P) at VGS = 10 V, rated for 2.7 A/−2.0 A continuous drain current at 25°C, used in compact DC-DC converters and H-bridge motor drivers.
For engineers reviewing the IRF7509TR datasheet, IRF7509TR pinout, IRF7509TR application, or IRF7509TR equivalent, key selection criteria include complementary channel pairing, ultra-low-profile (<1.1 mm) Micro8 footprint, fast switching capability, thermal resistance of 100°C/W, and lead-free RoHS-compliant construction.
Technical Context
This dual MOSFET implements complementary N+P topology in a single Micro8 outline-half the area of SO-8-with independent gate control enabling synchronous rectification and bidirectional current handling. Its Generation V HEXFET process delivers low RDS(on) per silicon area while maintaining rugged avalanche rating and 5.0 V/ns diode recovery dv/dt.
The device supports logic-level drive (VGS(th) = 1.0–2.5 V for N-channel; −1.0 to −2.5 V for P-channel), operates across −55°C to +150°C junction temperature, and features integrated body diodes with forward voltage of 1.2 V (N) and 1.4 V (P) at −1.2 A.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary dual MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 0.045 Ω (N), 0.12 Ω (P); higher Qg (15 nC/13 nC); SO-8 package (1.75 mm height) | Larger footprint and taller profile limit use in sub-1.6 mm devices | Preferred when higher current (3.5 A) and lower RDS(on) outweigh space constraints |
| DMN3028LSD-13 | RDS(on) = 0.032 Ω (N), 0.055 Ω (P); Micro8 package; but only rated to −20 V P-channel | Insufficient P-channel voltage rating for 24 V systems requiring reverse polarity protection | Optimal for 12 V automotive body electronics where lower on-resistance justifies reduced VDS margin |
Compared with Si7157DP and DMN3028LSD, IRF7509TR uniquely balances 30 V/−30 V symmetry, Micro8 footprint, and sub-1.1 mm height-making it the only option qualified for space- and height-critical 24 V portable power systems.

FAQ
What is the maximum junction temperature for reliable operation?
The IRF7509TR has a specified junction temperature range of −55°C to +150°C. Continuous operation above 150°C risks permanent parametric shift and bond wire failure. Derating begins at 25°C ambient, with linear reduction of 10 mW/°C beyond 25°C, ensuring safe operation up to 70°C ambient at full rated current.
Can IRF7509TR be used in synchronous buck converters without external bootstrap circuitry?
Yes-the N-channel MOSFET can serve as the low-side switch directly referenced to ground, eliminating bootstrap complexity. For high-side N-MOS use, a dedicated gate driver with floating supply (e.g., IR2104) is required. The integrated P-channel enables true high-side switching without auxiliary circuitry in low-voltage buck stages.
Is the thermal pad (pins 7 and 8) electrically isolated or internally connected?
Pins 7 and 8 are exposed thermal pads internally connected to the drain terminals of both MOSFETs (D1 and D2). They must be soldered to a common PCB copper pour tied to the system ground plane or appropriate power rail to meet thermal resistance specifications and prevent floating potential hazards.
Does IRF7509TR support 3.3 V logic-level gate drive for both channels?
The N-channel turns on fully at VGS ≥ 4.5 V (RDS(on) = 0.08 Ω), making 3.3 V drive marginal for low-loss operation. The P-channel requires VGS ≤ −3.3 V for robust conduction; 3.3 V logic alone cannot achieve this-level-shifting or inverting gate drive is necessary for full enhancement of both channels.
