Product details

Overview

STD90N02L-1 from STMicroelectronics is an N-channel 25V Power MOSFET in IPAK package, featuring R_DS(on) = 0.0052 Ω (at V_GS = 10 V, I_D = 30 A), 60 A continuous drain current at T_C = 25°C, and low gate charge (Q_g = 17 nC). It is optimized for high-efficiency synchronous buck converters as a low-side switch.

For engineers reviewing the STD90N02L-1 datasheet, STD90N02L-1 pinout, STD90N02L-1 application, or STD90N02L-1 equivalent, key selection criteria include conduction loss minimization via ultra-low R_DS(on), switching loss reduction through low Q_g and Q_oss, thermal performance governed by R_thj-case = 2.14 °C/W, and suitability for DC-DC converter topologies requiring robust avalanche capability (E_AS = 360 mJ).

Technical Context

This STripFET™ III device employs advanced trench-gate technology to achieve industry-leading R_DS(on) × Q_g product, enabling high-frequency operation with minimal conduction and switching losses. Its low threshold voltage (V_GS(th) = 1–1.8 V) supports 5 V gate drive compatibility.

The MOSFET is characterized for unclamped inductive switching with guaranteed avalanche energy rating, and its dynamic parameters-including C_iss = 2050 pF, C_oss = 545 pF, and Q_rr = 65 nC-are specified under standardized test conditions (V_DD = 10 V, I_D = 30 A, R_G = 4.7 Ω) to support accurate power loss modeling in synchronous buck stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	25 V - Maximum drain-source blocking voltage; defines safe operating range in 12–24 V input DC-DC systems.
R_DS(on)	0.0052 Ω @ V_GS = 10 V - Enables <1.8 W conduction loss at 60 A, critical for high-current low-voltage output rails.
I_D (continuous)	60 A @ T_C = 25°C - Supports high-power density designs without forced air cooling at moderate case temperatures.
Q_g	17 nC - Reduces gate driver power consumption and enables fast turn-on/turn-off (t_r = 110 ns, t_f = 8 ns).
E_AS	360 mJ - Ensures ruggedness against inductive switching transients in non-zero-voltage-switched topologies.
R_thj-case	2.14 °C/W - Allows direct heatsinking to PCB copper or external metal; junction-to-case thermal path dominates thermal design.
Q_rr	65 nC - Minimizes reverse recovery loss in synchronous rectification, especially when paired with high-side FETs.

Pinout & Package

STD90N02L-1 is housed in an IPAK (TO-251) surface-mount package with three terminals: Drain (pins 1 & 3 tied internally), Source (pin 2), and Gate (pin 1, isolated). The package features exposed drain pad for enhanced thermal dissipation and complies with ECOPACK® environmental standards.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Drain)	Main current-carrying terminal (high-side connection point)	Internally connected to Pin 3; serves as primary heat path to PCB copper pour or heatsink.
Pin 2 (Source)	Reference node for gate drive and current return path	Low-inductance source connection essential for minimizing shoot-through risk in synchronous buck layout.
Pin 3 (Drain)	Secondary drain connection (common with Pin 1)	Provides redundant current path and mechanical stability; must be soldered to same copper area as Pin 1.

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g product	Industry benchmark for efficiency in high-frequency DC-DC converters; reduces combined conduction + switching loss.
Low gate threshold voltage	V_GS(th) = 1–1.8 V enables reliable turn-on with standard 5 V logic-level drivers, eliminating need for level shifters.
High avalanche energy rating	E_AS = 360 mJ ensures robustness during transient overloads without external snubbers in hard-switched applications.
Optimized for low-side switching	Low Q_rr (65 nC) and fast diode recovery (t_rr = 36 ns) minimize cross-conduction losses when used as synchronous rectifier.

Applications

IC Role / Device Role / Timing Role: Primary low-side switch in single-phase buck stage handling up to 60 A continuous output current.

Use Value: 360 mJ single-pulse avalanche rating withstands inductive kickback from solenoid or relay loads during fault events.

Telecom Rectifier Module

Automotive Body Control Unit

Use Scenario: 48 V telecom rectifier output stage stepping down to 12 V for fan controllers and interface ICs.

IC Role / Device Role / Timing Role: High-current synchronous rectifier in fixed-frequency (500 kHz) buck converter with tight thermal constraints.

Use Value: R_thj-case = 2.14 °C/W allows direct mounting to aluminum heatsink, maintaining T_j < 125°C at 42 A continuous (T_C = 100°C).

Use Scenario: 12 V battery-fed power distribution for LED lighting, window lift, and HVAC actuators.

IC Role / Device Role / Timing Role: Load switch and PWM-controlled power stage in compact BCU modules with space-constrained PCB layouts.

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
IRLZ44NPBF	R_DS(on) = 0.028 Ω @ 10 V (5.4× higher); Q_g = 67 nC (3.9× higher); TO-220 package	Higher conduction + gate loss; unsuitable for >300 kHz or >30 A continuous operation	Select only if cost sensitivity outweighs efficiency and thermal requirements; requires larger heatsink.
STP90NF03L	V_DSS = 30 V; R_DS(on) = 0.0055 Ω @ 10 V; DPAK package; Q_g = 19 nC	Slightly higher R_DS(on) and gate charge; lower thermal resistance (R_thj-case = 1.75 °C/W) but larger footprint	Prefer for higher voltage margin (30 V) or better thermal performance where board space permits DPAK.

Compared with IRLZ44NPBF and STP90NF03L, STD90N02L-1 delivers the lowest R_DS(on) × Q_g product in IPAK, enabling highest efficiency in space-constrained, high-current synchronous buck designs below 25 V input.

FAQ

Is STD90N02L-1 suitable for 5 V gate drive?

Yes. With V_GS(th) of 1–1.8 V and R_DS(on) fully specified at V_GS = 5 V (0.007 Ω), it is explicitly designed for logic-level gate drive. At 5 V, it delivers 15 A continuous current with low on-resistance, making it ideal for microcontroller-driven power stages without gate drivers.

What is the maximum safe operating temperature for continuous operation?

The device supports continuous operation up to T_j = 175°C, with derated current: 42 A at T_C = 100°C. To maintain reliability, junction temperature must stay below 175°C-achievable with R_thj-case = 2.14 °C/W and proper PCB copper area or heatsink, given P_TOT = 70 W at T_C = 25°C.

Does STD90N02L-1 have integrated ESD protection?

No. STD90N02L-1 does not include on-chip ESD protection diodes. External gate protection (e.g., 10–22 Ω series resistor + 12 V Zener clamp) is required per ST's application guidance to prevent damage from human-body-model (HBM) or charged-device-model (CDM) events during handling or PCB assembly.

Can it replace STD90N02L in existing designs?

Yes-STD90N02L-1 is the IPAK variant of STD90N02L (DPAK), sharing identical electrical specifications, thermal ratings, and pinout functionality. Mechanical redesign is required only for footprint adaptation; no circuit or layout changes are needed for equivalent performance in thermally constrained applications.
