Product details

Overview

IRFZ48VSTRLPBF from Infineon Technologies (formerly International Rectifier) is a 60 V, 72 A, 12 mΩ D2PAK surface-mount N-channel HEXFET® Power MOSFET optimized for high-efficiency switch-mode power supplies and motor control. It features fully avalanche-rated operation, 166 mJ single-pulse avalanche energy, and fast switching with 7.6 ns turn-on delay and 166 ns fall time.

For engineers reviewing the IRFZ48VSTRLPBF datasheet, IRFZ48VSTRLPBF pinout, IRFZ48VSTRLPBF application, or IRFZ48VSTRLPBF equivalent, key selection criteria include R_DS(on) at 10 V gate drive, thermal resistance (R_θJC = 1.0 °C/W), diode reverse recovery charge (Q_rr = 155–233 nC), and D2PAK package compatibility with high-current PCB layouts.

Technical Context

This MOSFET employs advanced planar HEXFET processing to achieve ultra-low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its gate charge profile (Q_g = 110 nC, Q_gd = 36 nC) supports efficient hard-switching in DC-DC converters up to several hundred kHz.

The integrated body diode exhibits 70–100 ns reverse recovery time (t_rr) and 2.0 V forward voltage (V_SD) at 72 A, enabling synchronous rectification and freewheeling in half-bridge topologies without external diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum blocking voltage before avalanche onset; sets upper limit for bus voltage in SMPS and motor drives.
R_DS(on)	12 mΩ @ V_GS = 10 V, I_D = 43 A - Directly determines conduction loss and junction temperature rise under load.
I_D (T_C = 25°C)	72 A - Continuous drain current rating at case temperature 25°C; defines maximum steady-state output capability with heatsinking.
E_AS	166 mJ - Single-pulse avalanche energy rating; enables reliable operation during inductive load switching transients.
Q_g	110 nC - Total gate charge required for full enhancement; determines driver strength and switching loss trade-off.
t_rr	70–100 ns - Body diode reverse recovery time; critical for minimizing shoot-through risk and EMI in bridge configurations.
R_θJC	1.0 °C/W - Junction-to-case thermal resistance; enables accurate thermal design when mounted to heatsink via insulated pad or direct metal interface.

Pinout & Package

The IRFZ48VSTRLPBF is housed in a D2PAK (TO-263) surface-mount package with exposed drain tab for thermal and electrical connection. The package supports high-current routing and offers low internal inductance (L_D, L_S specified).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically and thermally connected to PCB copper pour; requires isolation if floating ground topology is used.
Source	Reference node for gate drive and current sensing	Low-inductance connection essential for stable gate control and accurate shunt-based current monitoring.
Gate	Control terminal for channel modulation	High-impedance input requiring <20 V absolute max; sensitive to ringing-requires local RC snubber or gate resistor tuning.

Key Features

Feature	Design Value
Fully avalanche rated	Withstands unclamped inductive switching up to 166 mJ single-pulse and 15 mJ repetitive, eliminating need for external clamping circuits in relay/motor drivers.
Ultra-low R_DS(on)	12 mΩ at 10 V drive reduces conduction losses by >30% vs. legacy 60 V MOSFETs, directly improving efficiency in 12–48 V systems.
D2PAK thermal performance	R_θJC = 1.0 °C/W enables >100 W dissipation with moderate heatsinking-critical for compact, fanless industrial power modules.
Optimized for SMPS	Low Q_gd/Q_g ratio (32.7%) and fast t_f (166 ns) minimize Miller-induced switching delays and improve light-load regulation in LLC and synchronous buck converters.

Applications

DC-DC Converters

Motor Drive Half-Bridge

Use Scenario: Primary-side switch in 48 V input, 12 V output synchronous buck converter for telecom power shelves.

IC Role / Device Role / Timing Role: High-side power switch operating at 250 kHz with 10 V gate drive and 72 A peak current.

Use Scenario: Low-side switch in 24 V brushed DC motor H-bridge for automated gate actuator.

IC Role / Device Role / Timing Role: PWM-controlled freewheeling path with body diode conducting reverse current during off-time.

Use Value: 70 ns t_rr and 2.0 V V_SD reduce diode conduction loss and prevent cross-conduction during dead-time transitions.

Uninterruptible Power Supplies

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
STP72NF60Z	60 V, 72 A, 13.5 mΩ; higher Q_g (140 nC); TO-220 package	Lacks surface-mount D2PAK form factor; higher R_θJA limits power density in compact designs	Prefer when through-hole mounting and lower gate drive complexity are prioritized over thermal performance.
IXTP72N10P	100 V, 72 A, 14 mΩ; higher V_DSS; TO-220 package; no avalanche rating	Higher voltage margin but no E_AS spec; unsuitable for unclamped inductive loads	Select only in fixed-bus applications where overvoltage transients are fully suppressed by external TVS/clamp networks.

Compared with STP72NF60Z and IXTP72N10P, the IRFZ48VSTRLPBF uniquely combines D2PAK surface-mount compatibility, 1.0 °C/W R_θJC, and certified avalanche ruggedness-making it the preferred choice for space-constrained, high-reliability SMPS and motor control designs where thermal management and transient robustness are co-critical.

FAQ

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

The absolute maximum V_GS is ±20 V. Operation beyond this risks irreversible gate oxide breakdown. For reliable 10 V enhancement, use gate drivers with tight voltage regulation and transient suppression-especially in noisy motor drive environments where ringing can exceed ratings.

Can IRFZ48VSTRLPBF be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) enables inherent current sharing. However, layout symmetry (matched gate and source inductance) and individual gate resistors (≥5 Ω) are mandatory to suppress oscillation and ensure balanced dynamic current distribution across paralleled devices.

Is the body diode suitable for continuous freewheeling?

The body diode is rated for continuous source current up to 72 A at T_C = 25°C, but its V_SD (2.0 V) and t_rr (70–100 ns) make it appropriate only for moderate-duty-cycle freewheeling. For high-frequency, high-current applications, external Schottky or SiC diodes are recommended to reduce conduction and switching losses.

Does IRFZ48VSTRLPBF require a heatsink in typical applications?

Yes-when dissipating >5 W continuously, a heatsink is required. With R_θJC = 1.0 °C/W and max T_J = 175°C, even at 25°C ambient, >150 W dissipation would require R_θCA < 1.0 °C/W. Most 72 A applications use bolt-down heatsinks or copper planes with thermal vias to maintain T_J < 130°C.
