Product details
Overview
IPDH4N03LAG from Infineon Technologies is a 25 V, logic-level N-channel OptiMOS®2 power MOSFET in PG-TO252-3-11 package, rated for 90 A continuous drain current at TC = 25 °C and featuring 4.2 mΩ max RDS(on) at VGS = 10 V. It delivers high-frequency switching performance in synchronous buck converters with 19–26 nC total gate charge and supports 175 °C junction operation.
For engineers reviewing the IPDH4N03LAG datasheet, IPDH4N03LAG pinout, IPDH4N03LAG application, or IPDH4N03LAG equivalent, key selection criteria include its low gate charge × RDS(on) figure of merit (FOM), robust 150 mJ single-pulse avalanche energy, and JEDEC-qualified reliability for industrial dc/dc converter designs requiring stable thermal resistance (RthJC = 1.6 K/W).
Technical Context
This device operates as a high-efficiency primary-side or synchronous rectifier switch in non-isolated point-of-load converters. Its logic-level gate threshold (1.2–2.0 V typ) enables direct drive from 3.3 V/5 V controllers, while low Crss (110–160 pF) and fast switching times (tr = 7–11 ns, tf = 4.6–7 ns) minimize switching losses at frequencies up to 1 MHz.
The integrated body diode exhibits 0.93–1.2 V forward voltage at 78 A and 25 °C, with 15 nC reverse recovery charge under 400 A/µs di/dt - enabling efficient hard-switched and synchronous rectification topologies without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 25 V - Maximum blocking voltage compatible with 12 V input bus systems and 5 V logic-level gate drive. |
| RDS(on) max | 4.2 mΩ at VGS = 10 V - Enables <1 W conduction loss at 50 A, critical for high-current POL converters. |
| ID cont. | 90 A at TC = 25 °C - Supports high-power density designs with minimal parallel devices. |
| Qg total | 19–26 nC - Low gate drive power requirement, reducing controller loading and enabling higher PWM frequency operation. |
| EAS | 150 mJ (ID = 90 A) - Robust avalanche capability eliminates need for external clamping in inductive load switching. |
| RthJC | 1.6 K/W - Enables direct heatsink mounting for thermal management in compact industrial power modules. |
| VGS(th) | 1.2–2.0 V - Ensures reliable turn-on with standard microcontroller GPIO or low-voltage PWM drivers. |
Pinout & Package
IPDH4N03LAG uses the PG-TO252-3-11 surface-mount package (DPAK variant), with exposed drain pad for thermal and electrical connection to PCB copper area. The three terminals are arranged in standard DPAK configuration: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control electrode | Receives logic-level gate drive signal; low input capacitance (Ciss = 2400–3200 pF) minimizes driver stress. |
| Pin 2 (Drain) | High-side power terminal | Exposed metal tab - must be soldered to ≥6 cm² copper pour for thermal performance and current conduction. |
| Pin 3 (Source) | Reference node / return path | Provides low-inductance source connection; ties to power ground plane to reduce switching noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 4.5 V - eliminates need for gate driver ICs in 3.3 V/5 V control systems. |
| Optimized FOM (Qg × RDS(on)) | ~100–110 nC·mΩ - balances switching and conduction losses for peak efficiency in 300–1000 kHz dc/dc converters. |
| 175 °C maximum junction temperature | Enables operation in sealed enclosures or high-ambient environments without derating beyond datasheet curves. |
| JEDEC-qualified reliability | Qualified per J-STD-20 and JESD22 - validated for reflow, humidity, and temperature cycling in industrial production. |
| Low reverse recovery charge (Qrr) | ≤15 nC - reduces diode-related switching loss and EMI in synchronous rectifier configurations. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLHS6342TRPBF | RDS(on) = 5.2 mΩ @ 4.5 V; Qg = 14.5 nC; TO-252 package; lower VDS (20 V) | Limited to ≤20 V input rails; better suited for ultra-low-voltage POL where gate drive is constrained to 3.3 V only. | Select when VIN ≤ 16 V and gate drive voltage is fixed at 3.3 V - trades voltage rating for slightly lower Qg. |
| STL220N4LF7AG | RDS(on) = 3.8 mΩ @ 10 V; Qg = 32 nC; same PG-TO252-3-11; 40 V VDS | Higher voltage rating enables 24 V input compatibility but increases switching loss due to 67% higher Qg. | Select when system requires 24–36 V input range and can accommodate higher gate drive power and slower switching. |
Compared with IRLHS6342TRPBF and STL220N4LF7AG, IPDH4N03LAG uniquely balances 25 V rating, sub-4.5 mΩ RDS(on), and <26 nC Qg - making it optimal for 12 V input, high-current, high-frequency industrial dc/dc where thermal and switching loss budgets are tightly coupled.

FAQ
Is IPDH4N03LAG suitable for synchronous rectification in flyback converters?
Yes - its low 0.93–1.2 V body diode forward voltage at 78 A and 15 nC reverse recovery charge enable efficient synchronous rectification without external diodes. The 175 °C junction rating supports sustained operation under high ambient conditions typical in enclosed flyback designs.
What is the recommended PCB layout for thermal performance?
Mount the exposed drain pad directly to ≥6 cm² of 70 µm thick copper on FR4 (40 mm × 40 mm), using multiple thermal vias to inner ground planes. Maintain ≥0.5 mm clearance between gate trace and high-dV/dt drain nodes to prevent coupling-induced false turn-on.
Does IPDH4N03LAG require a gate resistor for stability?
A 2.7 Ω gate resistor is used in the datasheet's switching characterization (td(off), tf). For most 300–1000 kHz applications, a 1–5 Ω resistor balances EMI suppression and switching speed; values below 1 Ω increase risk of ringing due to low RG (1.3 Ω typ) and Crss interaction.
Can IPDH4N03LAG replace IPSH4N03LAG in existing designs?
Yes - both share identical electrical specs, thermal characteristics, and marking (H4N03LA). The only difference is package: IPDH4N03LAG uses PG-TO252-3-11 (surface-mount DPAK), while IPSH4N03LAG uses PG-TO251-3-11 (SMD SIP). Footprint and thermal design must be verified for the TO252 variant's larger pad area.
