Product details

Overview

IRFU210 from Vishay Siliconix is a 200 V, 2.6 A N-channel enhancement-mode power MOSFET in straight-lead IPAK (TO-251) package, optimized for through-hole mounting in DC-DC converters, motor control, and power supply switching circuits with R_DS(on) = 1.5 Ω at V_GS = 10 V and Q_g = 8.2 nC.

For engineers reviewing the IRFU210 datasheet, IRFU210 pinout, IRFU210 application, or IRFU210 equivalent, this discrete MOSFET delivers ruggedized avalanche capability (E_AS = 95 mJ), fast switching (t_r = 17 ns), and dynamic dV/dt immunity (5.0 V/ns) - critical for reliable operation in inductive load switching and unclamped inductive turn-off.

Technical Context

The IRFU210 employs third-generation trench-gate silicon technology to achieve low conduction loss and high ruggedness. Its design integrates a robust body diode (t_rr = 150–310 ns, Q_rr = 0.60–1.4 μC) and supports repetitive avalanche operation up to I_AR = 2.7 A and E_AR = 2.5 mJ under defined pulse conditions.

Thermal performance is specified for PCB-mount operation (R_thJA = 50 °C/W on 1" FR-4) and case-mount use (R_thJC = 5.0 °C/W), enabling thermal design flexibility across low-power industrial and embedded power stages where continuous ID = 1.7 A at T_C = 100 °C is required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports input rails up to 160 V DC with margin for voltage transients in offline and battery-fed systems
R_DS(on)	1.5 Ω @ V_GS = 10 V - determines conduction loss of ~6.25 W at 2.6 A, defining thermal limits in continuous operation
Q_g	8.2 nC - sets gate drive power requirement and switching speed; enables <25 ns total switching time with 24 Ω gate resistor
E_AS	95 mJ - allows safe single-pulse energy absorption during inductive turn-off without external snubbers
dV/dt Rating	5.0 V/ns - prevents false turn-on during high-slew-rate voltage transients in half-bridge or flyback topologies
T_J Range	−55 to +150 °C - ensures functionality across automotive under-hood and industrial ambient conditions

Pinout & Package

IRFU210 uses the IPAK (TO-251) straight-lead package with three terminals: Gate (G), Drain (D), and Source (S). The drain tab is internally connected to the D lead and serves as the primary heat path; mounting requires mechanical anchoring and thermal via placement beneath the tab.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	Receives 10 V logic-level drive; threshold V_GS(th) = 2.0–4.0 V ensures compatibility with standard microcontroller GPIOs
D	Drain current output	High-side or low-side switch node; connects to load/inductor; tab is electrically tied to D and must be isolated from ground unless used as heatsink
S	Source return path	Reference node for gate drive; ties to system ground or floating return; body diode anode is internal to S

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation in unclamped inductive switching (e.g., relay drivers, solenoid controls) without external protection
Dynamic dV/dt rating	5.0 V/ns immunity eliminates need for gate resistors >25 Ω in noisy environments, reducing gate drive losses
Through-hole straight-lead mounting	IPAK (TO-251) footprint provides mechanical stability and higher vibration tolerance than surface-mount alternatives
Fast switching with low Q_g	8.2 nC total gate charge enables sub-50 ns switching transitions, minimizing overlap loss in PWM applications

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
IRFR210	Same die, DPAK (TO-252) surface-mount package; R_thJA = 110 °C/W (vs. 50 °C/W for IRFU210 PCB mount)	Requires reflow-compatible layout; unsuitable for high-vibration or manual assembly environments	Select IRFR210 only when automated SMT production and space-constrained PCBs are prioritized over mechanical robustness.
STP2NK20Z	200 V, 2.2 A, R_DS(on) = 1.8 Ω, Q_g = 7.5 nC; Zener-protected gate; different pinout (TO-220)	Larger TO-220 footprint; gate protection adds 10–15 V ESD tolerance but increases gate capacitance slightly	Choose STP2NK20Z when gate robustness in high-noise factory floors outweighs compactness and thermal efficiency.

Compared with IRFR210 and STP2NK20Z, the IRFU210 offers superior thermal resistance in PCB-mount configurations (R_thJA = 50 °C/W), making it preferred for thermally constrained through-hole designs where reliability under mechanical stress is critical.

FAQ

What is the maximum continuous drain current for IRFU210 at 100 °C case temperature?

The IRFU210 supports a continuous drain current of 1.7 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK (TO-251) package when mounted on standard PCBs; actual current capability depends on heatsinking and ambient conditions. Always verify junction temperature using R_thJC = 5.0 °C/W and power dissipation calculations in the final layout.

Does IRFU210 have a built-in body diode, and what are its key parameters?

Yes, the IRFU210 integrates a parasitic body diode between source and drain. Key parameters include forward voltage V_SD = 2.0 V at I_S = 2.6 A and T_J = 25 °C, reverse recovery time t_rr = 150–310 ns, and reverse recovery charge Q_rr = 0.60–1.4 μC. These values are critical for freewheeling behavior in inductive switching applications and influence EMI and voltage overshoot.

Can IRFU210 be driven directly by a 3.3 V microcontroller GPIO?

No - the IRFU210 has a gate threshold voltage V_GS(th) of 2.0–4.0 V and requires ≥10 V for full enhancement (R_DS(on) = 1.5 Ω). A 3.3 V GPIO cannot reliably turn it on; use a gate driver IC or level-shifting circuit. For logic-level compatibility, consider alternatives like IRLU210 (V_GS(th) ≤ 2.0 V).

What is the avalanche energy rating of IRFU210, and how is it tested?

The IRFU210 is rated for single-pulse avalanche energy E_AS = 95 mJ, measured under conditions of V_DD = 50 V, starting T_J = 25 °C, L = 28 mH, R_g = 25 Ω, and I_AS = 2.6 A. This rating validates safe operation during unclamped inductive switching events, such as relay coil de-energization or motor phase interruption, without device failure.

Is IRFU210 RoHS-compliant and halogen-free?

Yes - the IRFU210PbF variant is lead (Pb)-free and complies with RoHS Directive 2011/65/EU. Vishay also offers halogen-free versions (e.g., IRFU210-GE3), confirmed per material categorization document 99912. Full compliance documentation, including test reports and declarations, is available upon request from Aetrix Electronics.
