Product details
Overview
STC5NF30V from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TSSOP8 package, rated for 30V VDS, 5A continuous drain current at 25°C, and ultra-low 2.7V gate threshold voltage-enabling direct drive from 3.3V logic. Its 0.027Ω RDS(on) @ 4.5V supports high-efficiency low-voltage switching in battery-powered DC-DC converters.
For engineers reviewing the STC5NF30V datasheet, STC5NF30V pinout, STC5NF30V application, or STC5NF30V equivalent, key selection criteria include verified 2.7V logic-level gate drive compatibility, TSSOP8 thermal performance on FR-4 (RthJ-PBC = 100°C/W), and rugged unclamped inductive switching capability up to 20A pulsed drain current.
Technical Context
This device uses ST's STripFET™ II strip-based process with Single Feature Size™ architecture, delivering high cell density and tight parameter distribution. It features a built-in source-drain diode with 1.2V forward voltage at 5A and 26ns reverse recovery time under 100A/µs di/dt conditions.
The MOSFET operates across –55°C to 150°C junction temperature range and supports safe operating area (SOA) limited pulse currents up to 20A. Gate charge is fully characterized: Qg = 8.5nC, Qgs = 1.8nC, Qgd = 2.4nC at VDD = 16V and ID = 4.5A.

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 |
|---|---|---|---|
| STP5NF30L | TO-220 package, higher RDS(on) (0.035Ω @ 4.5V), 5A rating same | Requires heatsink for >2A continuous; unsuitable for space-constrained PCBs | Select when higher power dissipation (>1.5W) and manual assembly are acceptable |
| DMN3025LSD-13 | SOT-23-6 package, lower ID (3.5A), RDS(on) = 0.025Ω @ 4.5V | Limited thermal mass; derated to 2A continuous on standard FR-4 | Select only for ultra-low-current (<2A), ultra-small-footprint applications |
Compared with STP5NF30L and DMN3025LSD-13, STC5NF30V uniquely balances TSSOP8 surface-mount compatibility, 5A continuous rating, and 2.7V gate drive-making it optimal for automated assembly of compact, medium-power switching stages where thermal management and logic-level simplicity are jointly critical.

FAQ
Is STC5NF30V still in active production?
No-STC5NF30V is marked as Obsolete Product(s) in the official ST datasheet revision history (Rev 2, Aug 2006). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle coordination support for ongoing production programs requiring this specific TSSOP8 footprint and 2.7V drive behavior.
What is the maximum continuous drain current at 85°C case temperature?
Per Table 1, the continuous drain current is derated linearly from 5A at 25°C to 3A at 100°C. At 85°C case temperature, the maximum continuous ID is approximately 3.6A, calculated using the specified thermal derating slope of –0.033A/°C above 25°C.
Can STC5NF30V replace STB5NF30 in the same PCB layout?
No-STB5NF30 uses TO-263 (D2PAK) package with different pinout, thermal pad configuration, and mounting requirements. STC5NF30V's TSSOP8 footprint is incompatible; mechanical redesign and thermal validation would be required for substitution.
Does the exposed pad (pins 5–8) require electrical connection?
Yes-the exposed pad is internally connected to the source terminal and must be soldered to a PCB copper pour for both electrical functionality and thermal performance. Omitting this connection increases RthJ-PBC beyond the rated 100°C/W and risks thermal runaway under 3A+ loads.
