Product details

Overview

IRLH5036TR2PBF from Infineon Technologies is a 60 V, 100 A N-channel enhancement-mode HEXFET Power MOSFET in PQFN 5×6 mm package, optimized for high-current synchronous rectification and DC-DC brick applications with R_DS(on) = 4.4 mΩ @ V_GS = 4.5 V, Q_g = 44 nC, and R_θJ-mb = 0.8 °C/W.

For engineers reviewing the IRLH5036TR2PBF datasheet, IRLH5036TR2PBF pinout, IRLH5036TR2PBF application, or IRLH5036TR2PBF equivalent, key selection criteria include low-voltage gate drive compatibility (V_GS(th) = 1.0–2.5 V), industry-standard pinout for multi-vendor PCB reuse, and MSL1 industrial qualification for high-reliability power conversion designs.

Technical Context

This MOSFET employs trench-gate silicon technology to achieve sub-5 mΩ on-resistance at 4.5 V gate drive, enabling efficient operation in 12–48 V input DC-DC converters where gate bias is constrained by controller output voltage. Its low Q_gd/Q_g ratio (18/44 nC) supports fast, controllable switching with reduced Miller-induced shoot-through risk.

The device integrates a robust body diode with t_rr = 28–42 ns and Q_rr = 134–201 nC, validated for unclamped inductive switching up to E_AS = 286 mJ at T_J = 25°C. Thermal design leverages direct-mounting base (R_θJ-mb ≤ 0.8 °C/W) for high-power density layouts without heatsinks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Supports 48 V bus systems with 20 % safety margin against transients
R_DS(on) max @ V_GS = 4.5 V	5.5 mΩ - Enables <1.4 W conduction loss at 50 A, critical for thermally constrained bricks
Q_g typical	44 nC - Matches standard PWM controllers (e.g., UCC27531) without gate driver oversizing
I_D @ T_mb = 25°C	100 A - Sustains full-load current in secondary-side rectifiers without derating
R_θJ-mb max	0.8 °C/W - Allows >90 W power dissipation with 72 °C temperature rise over mounting base
V_GS(th)	1.0–2.5 V - Ensures turn-on with 3.3 V or 5 V logic-level drivers, eliminating level shifters
t_rr	28–42 ns - Minimizes reverse recovery losses in high-frequency synchronous rectification

Pinout & Package

PQFN 5×6 mm Outline "B" package with exposed thermal pad (pin 1 identifier marked), designed for solder-reflow mounting and direct thermal coupling to PCB copper planes. Package complies with MSL1 and RoHS.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path collector	Internally connected to exposed thermal pad; must be soldered to large copper pour for thermal management
Source (S)	Current return node / reference	Common source connection for gate drive loop; low-inductance layout essential for stability
Gate (G)	Control terminal	High-impedance input requiring <1.2 Ω series resistance to damp ringing during fast switching

Key Features

Feature	Design Value
Low-profile PQFN package	Height < 0.9 mm - Enables ultra-thin DC-DC modules meeting 1U server or telecom blade height constraints
100 % R_G tested	Gate resistance verified per unit - Eliminates batch-level gate oscillation risk in parallel configurations
Industry-standard pinout	Drain-Source-Gate sequence matches IRF, ST, ON Semi equivalents - Enables drop-in replacement on existing footprints
Low R_DS(on) @ 4.5 V	4.4 mΩ typical - Reduces conduction loss by 35 % vs. legacy 10 V gate MOSFETs in 5 V-controlled systems
MSL1 qualification	Moisture sensitivity level 1 - Permits unlimited floor life and standard reflow without baking

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFH5020TR2PBF	R_DS(on) = 2.0 mΩ @ 10 V, but 6.0 mΩ @ 4.5 V; Q_g = 52 nC	Higher gate charge increases driver loss; better suited for 10 V gate drive systems	Select when system uses 10 V gate drivers and requires lower R_DS(on) at higher V_GS
STL220N6F7AG	R_DS(on) = 3.8 mΩ @ 4.5 V; PQFN 5×6 but non-MSL1; no 100 % R_G test	Lacks industrial moisture rating and gate resistance screening; higher risk in high-reliability production	Acceptable for cost-sensitive consumer designs where MSL1 and R_G traceability are not required

Compared with IRLH5036TR2PBF, IRFH5020TR2PBF trades higher gate drive dependency for lower on-resistance at 10 V, while STL220N6F7AG offers marginally better R_DS(on) but omits MSL1 qualification and gate resistance testing-critical for telecom and industrial deployments.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The IRLH5036TR2PBF supports 40 A continuous drain current at T_mb = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PQFN 5×6 package and assumes proper PCB copper area (≥1000 mm²) and 2 oz copper thickness for mounting base thermal transfer.

Does this MOSFET require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to control dV/dt and suppress oscillation. A 1.2 Ω series resistor is recommended based on the device's typical R_G = 1.2 Ω and gate charge profile; values between 1.0 Ω and 2.2 Ω balance switching speed and EMI, especially in paralleled configurations.

Can the body diode be used for freewheeling in a buck converter?

Yes-the integrated body diode is rated for 100 A continuous source current and exhibits t_rr = 28–42 ns with Q_rr = 134–201 nC. It is suitable for freewheeling in medium-frequency buck converters (<500 kHz), though synchronous rectification with external gate control yields lower losses.

Is the exposed thermal pad electrically connected to the drain?

Yes-the exposed thermal pad is internally tied to the drain (D) terminal. It must be soldered to a PCB copper plane designated as drain net and thermally coupled to system ground plane only through isolation if required; no floating or insulated mounting is permitted.
