Product details

Overview

IRFP150N from Infineon Technologies (formerly International Rectifier) is a 100V, 42A N-channel enhancement-mode power MOSFET in TO-247AC package, featuring 0.036Ω R_DS(on) at V_GS = 10V, 175°C maximum junction temperature, and full unclamped avalanche rating. It delivers high-efficiency switching in DC-DC converters, motor drives, and UPS systems where robustness and thermal stability are critical.

For engineers reviewing the IRFP150N datasheet, IRFP150N pinout, IRFP150N application, or IRFP150N equivalent, key selection criteria include its 140A pulsed drain current capability, 110nC total gate charge, 5.0V/ns peak diode recovery dv/dt rating, and isolated mounting hole enabling reliable heatsinking in high-power industrial designs.

Technical Context

This fifth-generation HEXFET uses advanced silicon processing to minimize conduction loss while maintaining fast switching (t_r = 56ns, t_f = 40ns) and rugged transient performance. Its body diode exhibits 180–270ns reverse recovery time and 1.2–1.8µC Q_rr, supporting hard-switched topologies with controlled commutation stress.

The device integrates low-inductance internal layout (L_D = 5.0nH, L_S = 5.0nH) and supports gate drive voltages up to ±20V. Its 0.95°C/W junction-to-case thermal resistance enables 160W continuous dissipation at T_C = 25°C, with linear derating to zero at 175°C case temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100V - Withstands 100V drain-source blocking voltage before breakdown, suitable for 48V bus and 100V DC-link applications.
R_DS(on)	0.036Ω - Enables ≤1.7W conduction loss at 42A continuous drain current, reducing thermal load in high-current switches.
I_D @ 25°C	42A - Supports high steady-state current in power supplies and motor phase legs without forced air cooling.
E_AS	420mJ - Fully rated for single-pulse inductive energy absorption, eliminating need for external snubbers in relay or solenoid drive circuits.
Q_g	110nC - Determines gate driver strength requirement; necessitates ≥2A peak gate current for 100ns turn-on in 100kHz PWM designs.
dv/dt Rating	5.0V/ns - Specifies maximum rate of voltage rise across drain-source during diode recovery, critical for EMI control in bridge configurations.
T_J Max	175°C - Allows operation in sealed enclosures or high-ambient environments without derating below rated current.

Pinout & Package

IRFP150N is housed in a TO-247AC package with isolated mounting hole, enabling direct mechanical attachment to heatsinks without electrical isolation hardware. The package provides low thermal resistance (R_θJC = 0.95°C/W) and high power handling in commercial-industrial applications.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives 10V logic-level gate drive to fully enhance channel; requires 110nC charge for full turn-on.
2 (Drain)	Main current output terminal	Connected to high-side switch node or DC-link; electrically tied to metal tab for thermal conduction.
3 (Source)	Main current return path	Serves as reference for gate drive and current sensing; internal source inductance (5.0nH) affects switching waveform fidelity.

Key Features

Feature	Design Value
Fifth-generation HEXFET process	Delivers 0.036Ω R_DS(on) in TO-247AC, achieving 22% lower on-resistance than prior generation at same die size.
Full avalanche rating	Guarantees 420mJ single-pulse energy survival without degradation, enabling use in unclamped inductive loads like solenoids and relays.
Isolated mounting hole	Eliminates need for insulating washers when mounting to grounded heatsinks, reducing thermal interface resistance by ~0.2°C/W.
175°C junction rating	Supports operation in automotive under-hood or industrial control cabinets where ambient exceeds 85°C.

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
STP14NK100Z	1000V V_DSS, 14A I_D, 0.75Ω R_DS(on), TO-220 package	Higher voltage rating but lower current and higher on-resistance; unsuitable for 42A continuous conduction.	Select only if system requires >600V blocking and space constraints prohibit TO-247 mounting.
IXTH30N50L	500V V_DSS, 30A I_D, 0.18Ω R_DS(on), TO-247 package	Lower voltage rating and higher on-resistance; lacks full avalanche rating per datasheet.	Acceptable only in 400V-class systems where 42A current is not required and avalanche robustness is secondary.

Compared with STP14NK100Z and IXTH30N50L, IRFP150N uniquely balances 100V blocking, 42A current, 0.036Ω on-resistance, and guaranteed 420mJ avalanche energy-making it irreplaceable in high-current, thermally constrained 48V industrial power stages.

FAQ

What is the maximum gate-to-source voltage for safe operation?

The absolute maximum V_GS is ±20V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be limited to +10V to +15V for full enhancement and –5V to –10V for fast turn-off, avoiding Miller-induced false turn-on in high-dv/dt environments.

Can IRFP150N be used in synchronous rectification applications?

No-it is not optimized for synchronous rectification. Its body diode has relatively high V_SD (1.3V) and slow reverse recovery (180–270ns), resulting in higher conduction and switching losses compared to dedicated SR MOSFETs with low Q_rr and enhanced diode softness.

Does IRFP150N require a gate resistor for stability?

Yes-a series gate resistor (typically 3.6Ω to 22Ω) is required to dampen ringing caused by gate-drain capacitance (C_rss = 230pF) interacting with PCB trace inductance. Without it, overshoot and oscillation can exceed V_GS ratings and cause erratic switching behavior.

How does the TO-247AC package differ from standard TO-247?

TO-247AC features an electrically isolated mounting hole, unlike standard TO-247 where the tab is internally connected to the drain. This eliminates need for mica washers or silicone pads when mounting to grounded heatsinks, reducing thermal resistance by up to 0.25°C/W and simplifying mechanical assembly.
