Product details

Overview

STD36NH02L from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in DPAK (TO-252) package, rated for 24 V V_DSS, 30 A continuous drain current at T_C = 25°C, and 0.011 Ω typical R_DS(on) at V_GS = 10 V. It features low gate charge (15.5 nC), fast switching (t_f = 15 ns), and optimized for high-efficiency DC-DC converters in power supply modules.

For engineers reviewing the STD36NH02L datasheet, STD36NH02L pinout, STD36NH02L application, or STD36NH02L equivalent, key selection criteria include conduction loss minimization in 24 V synchronous buck stages, avalanche energy rating (200 mJ), thermal resistance (R_thj-case = 3.33 °C/W), and gate drive compatibility with 5 V–10 V logic-level controllers.

Technical Context

This STripFET™ III device employs advanced trench-gate process technology to achieve industry-leading R_DS(on) × Q_g product, directly reducing both conduction and switching losses. Its 24 V breakdown voltage and 0.011 Ω on-resistance support high-current, low-voltage synchronous rectification where voltage headroom is constrained.

The MOSFET integrates a robust body diode with 24 ns reverse recovery time and 1.5 V forward voltage at 15 A, enabling reliable operation in hard-switched inductive loads. Thermal design is supported by low junction-to-case resistance (3.33 °C/W) and JEDEC-standard DPAK footprint for efficient PCB copper thermal spreading.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	24 V - Maximum blocking voltage in DC-DC high-side or low-side switch position without avalanche stress under normal operation
R_DS(on) (typ)	0.011 Ω @ V_GS = 10 V, I_D = 15 A - Enables ≤5 W conduction loss at 30 A, critical for thermally constrained 24 V input converters
Q_g (tot)	15.5 nC - Reduces gate driver power demand and switching transition time, supporting >500 kHz PWM frequencies
t_f	15 ns @ R_G = 4.7 Ω - Limits switching loss during turn-off and improves EMI profile in high-frequency power stages
E_AS	200 mJ - Withstands single unclamped inductive energy events common in motor drive or converter startup faults
R_thj-case	3.33 °C/W - Allows direct heatsinking via PCB copper pour, enabling 45 W dissipation at ≤100°C case temperature
I_D (cont)	30 A @ T_C = 25°C - Sustains full-rated output current in compact power modules with active or passive cooling

Pinout & Package

STD36NH02L uses the standard DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection. The package complies with ECOPACK® environmental requirements and JEDEC MO-238 mechanical standards.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal (S)	Reference node for gate drive; connects to power ground or low-side return path in buck/synchronous rectifier topologies
Pin 2 (Gate)	Control terminal (G)	High-impedance MOSFET control input; requires <4.7 Ω series gate resistor to limit ringing and optimize t_r/t_f
Pin 3 (Drain)	Power output terminal (D)	Exposed metal pad - electrically and thermally connected to drain; must be soldered to large PCB copper area for heat dissipation

Key Features

Feature	Design Value
STripFET™ III trench-gate architecture	Delivers lowest R_DS(on) × Q_g ratio in 24 V class, directly lowering total power loss in high-duty-cycle applications
Low R_DS(on) at 5 V gate drive	0.013 Ω @ V_GS = 5 V enables direct interface with 5 V microcontrollers or PWM ICs without level-shifting
Robust body diode	1.5 V V_SD @ 15 A and 24 ns t_rr supports synchronous rectification and reduces need for external Schottky diodes
ECOPACK® lead-free construction	Meets RoHS Directive 2011/65/EU and JEDEC JESD97 marking standards for environmentally compliant manufacturing

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 24 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF7470PBF	R_DS(on) = 0.012 Ω @ 10 V, Q_g = 22 nC, D2PAK package	Higher gate charge increases driver loss; larger D2PAK requires more PCB area	Preferred when higher avalanche ruggedness (E_AS = 320 mJ) is prioritized over board space and switching speed
DMN2012LFG-7	R_DS(on) = 0.012 Ω @ 4.5 V, Q_g = 11.5 nC, 2×2 mm WDFN package	Smaller footprint but lower current rating (12 A) and no exposed drain pad for thermal relief	Selected for ultra-compact 24 V point-of-load regulators where peak current ≤12 A and thermal budget allows

Compared with IRF7470PBF and DMN2012LFG-7, STD36NH02L uniquely balances low R_DS(on), moderate Q_g, DPAK thermal performance, and 24 V system compatibility-making it optimal for cost-sensitive, medium-power 24 V industrial converters requiring proven reliability and manufacturability.

FAQ

Is STD36NH02L suitable for 5 V gate drive applications?

Yes. STD36NH02L specifies R_DS(on) = 0.013 Ω (max) at V_GS = 5 V and I_D = 15 A, confirming full enhancement with standard 5 V logic-level drivers. Gate threshold voltage is 1.0–2.5 V, ensuring reliable turn-on across temperature and process variation.

What is the maximum safe operating temperature for continuous operation?

The device supports continuous operation up to T_J = 175°C, with derating beginning at T_C = 25°C. At T_C = 100°C, the 30 A continuous current rating remains valid per Table 1, provided R_thj-case ≤ 3.33 °C/W is maintained via adequate PCB copper area.

Does STD36NH02L have built-in ESD protection?

No. STD36NH02L does not integrate on-die ESD protection structures. Gate oxide withstands ±20 V V_GS, but handling and PCB layout require external ESD safeguards-such as series gate resistors and TVS clamping-per ST AN4195 guidelines for MOSFET layout.

Can STD36NH02L replace older STripFET II devices like STD25NH02LT4?

Yes, with verified improvement. STD36NH02L offers 12% lower R_DS(on) (0.011 Ω vs. 0.0125 Ω) and 20% lower Q_g (15.5 nC vs. 19.5 nC) versus STD25NH02LT4, while maintaining identical DPAK footprint and pinout-enabling drop-in efficiency upgrades in existing 24 V power designs.
