Product details
Overview
STD100NH02LT4 from STMicroelectronics is an N-channel 24 V, 60 A, 4.2 mΩ RDS(on) Power MOSFET in DPAK package, utilizing STripFET™ II technology for high-efficiency DC-DC converters. It delivers low conduction loss (Pconduction = δ·IL²·RDS(on)), low gate charge (Qg = 62 nC), and fast switching (tr = 200 ns) in synchronous buck low-side switch applications.
For engineers reviewing the STD100NH02LT4 datasheet, STD100NH02LT4 pinout, STD100NH02LT4 application, or STD100NH02LT4 equivalent, this device is selected for high-current, low-voltage power stages where RDS(on), Qgls, Coss, and Qrr are critical for minimizing total power loss in synchronous rectification.
Technical Context
This MOSFET is optimized as a low-side switch in synchronous buck converters, with third-quadrant gate charge (Qgls = 56.5 nC) and low reverse recovery charge (Qrr = 58 µC) enabling efficient body-diode commutation. Its RDS(on) of 4.2 mΩ at VGS = 10 V and 30 A ensures minimal conduction loss under heavy load.
The device features low output capacitance (Coss = 1020 pF) and low gate-drain charge (Qgd = 8 nC), reducing switching loss and improving voltage transient immunity. Thermal resistance RthJC = 1.5 °C/W supports high-power operation with effective heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 24 V - Maximum drain-source blocking voltage for 24 V rail systems |
| RDS(on) | 4.2 mΩ @ VGS = 10 V, ID = 30 A - Enables <1.8 W conduction loss at 60 A |
| ID (cont) | 60 A @ TC = 25°C - Rated continuous current limited by wire bonding |
| Qg | 62 nC @ VDD = 10 V, ID = 30 A - Determines gate driver power and switching speed |
| Coss | 1020 pF @ VDS = 15 V - Impacts turn-off energy and resonant losses in hard-switched topologies |
| Qrr | 58 µC @ ISD = 60 A, di/dt = 100 A/µs - Directly contributes to high-side FET turn-on loss in synchronous buck |
| RthJC | 1.5 °C/W - Enables 67 W dissipation before junction exceeds 150°C with 100°C case temperature |
Pinout & Package
DPAK (TO-252) package with exposed drain pad for thermal and electrical connection; 3-terminal surface-mount configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side synchronous rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLHS6242PBF | RDS(on) = 3.2 mΩ @ 4.5 V but Qg = 42 nC; smaller DFN5 package (no exposed drain pad) | Lower gate drive voltage compatibility (4.5 V logic); unsuitable for >40 A due to thermal limitations | Prefer when driving from 3.3 V controllers and current ≤40 A with active cooling |
| DMTH6005LPS | RDS(on) = 4.8 mΩ @ 10 V, Qg = 55 nC, RthJC = 1.7 °C/W; same DPAK footprint | Slightly higher conduction loss but tighter Qg/Qgd ratio improves noise immunity in noisy automotive environments | Prefer when EMI robustness and AEC-Q101 qualification are mandatory over minimal RDS(on) |
Compared with IRLHS6242PBF and DMTH6005LPS, STD100NH02LT4 offers the lowest RDS(on) × Qg product in DPAK, making it optimal for high-current, thermally constrained 24 V buck stages where conduction loss dominates total loss budget.

FAQ
What is the maximum safe operating junction temperature for STD100NH02LT4?
The maximum operating junction temperature is 175°C, as specified in the Absolute Maximum Ratings table. Operation above this limit risks permanent degradation of the silicon die and bond wires. Derating begins at TC = 25°C with a thermal resistance of 1.5 °C/W junction-to-case, requiring careful PCB thermal design to maintain safe TJ under 60 A load.
Can STD100NH02LT4 be used as a high-side switch in a buck converter?
No-it is optimized as a low-side synchronous rectifier. Its gate threshold voltage (VGS(th) = 1.0–1.8 V) and lack of integrated bootstrap circuitry make it unsuitable for high-side floating gate drive. High-side use would require ≥24 V gate drive relative to source, exceeding its ±20 V VGS rating and risking gate oxide failure.
Is STD100NH02LT4 qualified for automotive applications?
STD100NH02LT4 is not AEC-Q101 qualified. While its TJ range (-55°C to 175°C) and construction meet some automotive environmental requirements, ST does not certify this part for automotive use. For ADAS or body control modules, DMTH6005LPS or ST's AEC-Q101-qualified STD100NH02L-1 (IPAK variant) should be selected instead.
What is the significance of Qgls = 56.5 nC in system-level design?
Qgls quantifies gate charge required to turn on the MOSFET while its source is driven negative relative to drain-critical during body-diode conduction in synchronous buck operation. A lower Qgls reduces gate driver power consumption and minimizes delay between body-diode turn-off and channel turn-on, directly lowering cross-conduction and reverse recovery losses in the complementary high-side switch.
