Product details
Overview
ISZ019N03L5SATMA1 from Infineon Technologies is an N-channel OptiMOSTM power MOSFET rated for 30 V drain-source voltage, 1.9 mΩ maximum RDS(on) at VGS = 4.5 V, and 40 A continuous drain current at TC = 25 °C. It features ultra-low gate charge (QG = 44 nC at 0–10 V), low QOSS (25 nC), and optimized figure-of-merit for high-frequency synchronous buck converters in server and GPU power stages.
For engineers reviewing the ISZ019N03L5SATMA1 datasheet, ISZ019N03L5SATMA1 pinout, ISZ019N03L5SATMA1 application, or ISZ019N03L5SATMA1 equivalent, key selection criteria include its 1.9 mΩ RDS(on) @ 4.5 V, 2.0 mΩ max RDS(on) @ 4.5 V/20 A, thermal resistance RthJC = 1.8 K/W, and TSDSON-8 FL package with exposed drain pad for enhanced thermal performance.
Technical Context
This MOSFET employs Infineon's OptiMOSTM process to achieve a gate charge × RDS(on) product optimized for high-efficiency, high-frequency switching in synchronous rectification and primary-side switching applications. Its low QGD (6.5 nC) and fast switching times (td(off) = 28 ns, tf = 4.6 ns) reduce switching losses in SMPS operating above 500 kHz.
The device integrates a robust body diode with QRR = 20 nC and VSD = 0.8 V @ 20 A, enabling reliable operation in hard-switched and synchronous buck topologies. Its JEDEC-qualified reliability and 150 °C maximum junction temperature support industrial and computing-grade thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 12 V and 24 V input rails in point-of-load converters |
| RDS(on), max | 1.9 mΩ @ VGS = 4.5 V - Enables <1 W conduction loss at 20 A, critical for high-current CPU/GPU VRMs |
| ID, cont | 40 A @ TC = 25 °C - Supports high-current output stages without parallel devices in compact form factors |
| QG | 44 nC (0–10 V) - Low gate drive energy reduces driver IC loading and enables efficient 1–2 MHz operation |
| RthJC | 1.8 K/W - Enables >70 W power dissipation with modest heatsinking; validated on 6 cm² PCB copper area |
| QOSS | 25 nC - Minimizes turn-off energy loss and improves light-load efficiency in high-frequency SMPS |
| VGS(th) | 1.2–2.0 V - Ensures robust turn-on with standard 3.3 V or 5 V logic-level gate drivers |
Pinout & Package
TSDSON-8 FL (Thin Small Outline No-Lead, Flat Lead) package with exposed drain pad on bottom side for optimal thermal transfer. 5 mm × 6 mm footprint, 0.8 mm height, lead-free and halogen-free per IEC61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain) | Drain (common connection) | All pins 1–7 and pin 8 are internally connected to the drain terminal; pin 8 is the exposed thermal pad - must be soldered to PCB ground plane for thermal and electrical integrity |
| 1 (Source) | Source | Pin 1 is source terminal - used for low-side sensing and gate driver return path |
| 4 (Gate) | Gate | Pin 4 is gate input - requires low-inductance layout due to fast switching (tr = 6.8 ns, tf = 4.6 ns) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) × QG FOM | Enables >95% efficiency in 1 MHz+ buck converters by minimizing combined conduction and switching losses |

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 |
|---|---|---|---|
| IRF8721TRPBF | RDS(on) = 2.7 mΩ @ 4.5 V; QG = 14 nC; SO-8 package; RthJC = 3.5 K/W | Higher conduction loss and thermal resistance - suitable only for lower-current (<25 A), lower-frequency (<300 kHz) designs | Select when cost sensitivity outweighs efficiency and thermal performance; not recommended for server VRMs |
| BSC014N04LS6 | RDS(on) = 1.4 mΩ @ 4.5 V; QG = 47 nC; TSDSON-8; RthJC = 1.7 K/W | Lower RDS(on) but higher QG - better for low-frequency, high-current apps; slightly better thermal performance | Prefer for 300–600 kHz applications where conduction loss dominates; verify gate driver capability for 47 nC load |
Compared with IRF8721TRPBF and BSC014N04LS6, ISZ019N03L5SATMA1 delivers the best balance of ultra-low RDS(on), moderate QG, and industry-leading thermal resistance - making it optimal for high-frequency, high-current server and GPU power delivery where both efficiency and thermal headroom are constrained.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The ISZ019N03L5SATMA1 supports 40 A continuous drain current at TC = 25 °C, derating to 22 A at TC = 100 °C per the datasheet's maximum ratings table. This derating reflects thermal limits under typical PCB cooling conditions with 6 cm² copper area.
Is this MOSFET suitable for 3.3 V gate drive applications?
Yes - with a gate threshold voltage range of 1.2–2.0 V and guaranteed RDS(on) ≤ 2.0 mΩ at VGS = 4.5 V, the device fully enhances using standard 3.3 V logic-level gate drivers when paired with appropriate gate resistor selection to manage dV/dt and ringing.
Does the TSDSON-8 FL package require solder paste stencil optimization?
Yes - the exposed drain pad (pin 8) must be fully soldered to a thermally robust PCB copper pour. Recommended stencil aperture is 100% open area with 0.12 mm thickness; solder voiding should be limited to <20% per IPC-7095B to maintain RthJC ≤ 1.8 K/W.
What is the safe operating area (SOA) limitation at 100 µs pulse width?
Per Figure 3 in the datasheet, the SOA at tp = 100 µs allows up to 100 A at VDS = 10 V and 40 A at VDS = 30 V, assuming TC = 25 °C and single-pulse conditions. This supports robust short-circuit withstand in VRM overcurrent protection schemes.
