Product details

Overview

IRFU9220 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in TO-251 (IPAK) package, rated for -200 V drain-source voltage, 1.5 Ω R_DS(on) at V_GS = -10 V, and -3.6 A continuous drain current at T_C = 25 °C. It supports repetitive avalanche operation and fast switching in high-voltage DC-DC converters and motor control circuits.

For engineers reviewing the IRFU9220 datasheet, IRFU9220 pinout, IRFU9220 application, or IRFU9220 equivalent, this page delivers verified electrical specifications, thermal derating behavior, gate charge profile, body diode recovery characteristics, and real-world mounting guidance for through-hole PCB designs.

Technical Context

The IRFU9220 uses Vishay's third-generation Power MOSFET technology with optimized geometry for low R_DS(on) and high transconductance. Its P-channel structure enables high-side switching without level-shifting circuitry, and its -200 V V_DS rating supports industrial off-line and battery-backed systems.

It features dynamic dV/dt immunity up to -5.0 V/ns and is rated for repetitive avalanche energy of 4.2 mJ. The device includes an integral body diode with t_rr = 150–300 ns and Q_rr = 0.97–2.0 μC, enabling reliable freewheeling in inductive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-200 V - Supports high-voltage DC bus applications up to 200 V reverse polarity.
R_DS(on) @ V_GS = -10 V	1.5 Ω - Enables low conduction loss in 3–4 A load switching at ambient temperatures ≤100 °C.
I_D Continuous @ T_C = 25 °C	-3.6 A - Sustains steady-state current in heatsinked through-hole mounting configurations.
Q_g	20 nC - Determines gate drive power requirement; compatible with standard logic-level drivers.
t_r/t_f	27 ns / 19 ns - Enables sub-100 ns switching transitions in hard-switched topologies.
E_AS	310 mJ - Allows unclamped inductive switching without external snubbers in moderate-energy circuits.
R_thJC	3.0 °C/W - Confirms efficient heat transfer from die to case when mounted on metal-core or thick-copper PCBs.

Pinout & Package

IRFU9220 is housed in TO-251AA (IPAK) package - a through-hole variant of the DPAK footprint with bent leads for vertical PCB mounting. The package features a thermally enhanced drain tab for direct heatsink attachment and complies with JEDEC outline TO-251AA.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path output terminal	Connected to internal die substrate; electrically and thermally tied to exposed metal tab - must be isolated from PCB ground unless referenced to system common.
Gate (G)	Control electrode	High-impedance input requiring < ±100 nA leakage; driven by negative voltage relative to source to turn on; threshold range -2.0 to -4.0 V.
Source (S)	Reference node for gate drive and current return	Serves as return path for load current and reference for V_GS; body diode anode is internally connected here.

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables robust operation under inductive switching stress without external protection components.
Dynamic dV/dt immunity	-5.0 V/ns rating prevents false turn-on during high-slew-rate voltage transients in noisy environments.
Fast body diode recovery	t_rr = 150–300 ns and Q_rr = 0.97–2.0 μC reduce switching losses and EMI in freewheeling paths.
P-channel configuration	Eliminates need for high-side gate driver ICs in buck or half-bridge topologies where source is tied to positive rail.
TO-251 through-hole package	Provides mechanical stability and thermal reliability in industrial PCBs without surface-mount reflow constraints.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFR9220	Same die, but in surface-mount DPAK (TO-252) package; identical V_DS, R_DS(on), Q_g, and avalanche ratings.	Requires vapor-phase or IR reflow assembly; unsuitable for manual through-hole repair or high-vibration mechanical environments.	Select IRFR9220 only if board layout uses SMT footprint and thermal management relies on copper pour rather than heatsink mounting.
SiHFU9220	Identical TO-251 package and electrical specs; differs only in Vishay's material categorization (halogen-free, Pb-free per JEDEC J-STD-609).	No functional or performance difference; fully interchangeable in all electrical and mechanical contexts.	Choose SiHFU9220 for RoHS-compliant production runs where halogen-free compliance is mandated by end-equipment standards.

Compared with IRFU9220, IRFR9220 trades mechanical robustness and thermal interface flexibility for SMT manufacturability, while SiHFU9220 offers identical performance with updated environmental compliance - making IRFU9220 the preferred choice for legacy through-hole designs requiring field serviceability and heatsink coupling.

FAQ

What is the maximum continuous drain current for IRFU9220 at 100 °C case temperature?

The IRFU9220 supports -2.3 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-251 package under sustained power dissipation; actual usable current depends on PCB copper area, heatsinking, and ambient airflow. The IRFU9220 linear derating factor is 0.33 W/°C above 25 °C case temperature.

Does IRFU9220 have a built-in body diode, and what are its key parameters?

Yes, the IRFU9220 integrates a parasitic body diode with V_SD = -6.3 V at I_S = -3.6 A and T_J = 25 °C. Its reverse recovery time t_rr is 150–300 ns, and reverse recovery charge Q_rr is 0.97–2.0 μC under specified test conditions. These values enable predictable freewheeling in inductive loads but require careful layout to minimize ringing due to internal L_D = 4.5 nH and L_S = 7.5 nH.

Can IRFU9220 be used as a direct replacement for IRFR9220 in an existing design?

No - IRFU9220 and IRFR9220 share identical silicon die and electrical specifications but differ in package: IRFU9220 uses through-hole TO-251 (IPAK), while IRFR9220 uses surface-mount TO-252 (DPAK). Substituting one for the other requires PCB footprint redesign, rework of soldering process, and verification of thermal performance under identical mounting conditions. The IRFU9220 cannot be mounted on a DPAK land pattern.

What is the gate threshold voltage range for IRFU9220, and how does it affect drive requirements?

The IRFU9220 has a gate-source threshold voltage V_GS(th) ranging from -2.0 V to -4.0 V at I_D = -250 μA. This means full enhancement occurs only with V_GS ≤ -10 V, and partial conduction begins near -3 V. To ensure low R_DS(on) and avoid linear-mode operation, gate drive must deliver stable -10 V with sufficient current to charge 20 nC total gate charge within nanoseconds - typically requiring ≥10 mA peak drive capability.

Is IRFU9220 suitable for avalanche operation, and what are the limits?

Yes, the IRFU9220 is explicitly rated for repetitive avalanche operation with I_AR = -3.6 A and E_AR = 4.2 mJ per pulse, limited by junction temperature. Single-pulse avalanche energy is rated at 310 mJ. Safe operation requires adherence to the SOA curve (Fig. 7), pulse width restrictions (<300 μs), and duty cycle ≤2%. Avalanche testing must follow the unclamped inductive test circuit in Figure 12a of the datasheet.
