Product details
Overview
IRFR120ZTR from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 100 V VDSS, 8.7 A continuous drain current at TC = 25°C, and 190 mΩ RDS(on) at VGS = 10 V. It features 175°C junction temperature rating, fast switching (td(on) = 8.3 ns, tr = 26 ns), and tested repetitive avalanche capability-designed for high-efficiency DC-DC converters, motor control H-bridges, and industrial power supplies.
For engineers reviewing the IRFR120ZTR datasheet, IRFR120ZTR pinout, IRFR120ZTR application, or IRFR120ZTR equivalent, key selection criteria include its low RDS(on) at 10 V gate drive, robust avalanche energy rating (EAS = 18 mJ), thermal resistance (RθJC = 4.28°C/W), and D-Pak footprint compatibility with PCB-mount thermal management.
Technical Context
This MOSFET employs advanced silicon processing to minimize on-resistance per die area while maintaining ruggedness. Its gate threshold voltage (VGS(th) = 2.0–4.0 V) supports standard 5 V and 10 V logic-level drive, and its low Qg (6.9–10 nC) enables efficient high-frequency switching up to several hundred kHz.
The integrated body diode exhibits VSD = 1.3 V at 5.2 A and fast reverse recovery (trr = 24–36 ns, Qrr = 23–35 nC), making it suitable for synchronous rectification and freewheeling in hard-switched topologies where diode conduction and recovery losses must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - maximum blocking voltage before avalanche; defines use in 48 V input systems and 100 V bus applications |
| RDS(on) | 190 mΩ max at VGS = 10 V, TJ = 25°C - determines I²R conduction loss in continuous-current stages |
| ID (continuous) | 8.7 A at TC = 25°C - usable current level with adequate heatsinking on PCB copper |
| Qg | 6.9–10 nC - total gate charge defining driver strength requirement and switching loss trade-off |
| EAS | 18 mJ (tested) - single-pulse avalanche energy limit; enables unclamped inductive switching without failure |
| RθJC | 4.28°C/W - junction-to-case thermal resistance; enables direct heatsink mounting via tab for >35 W dissipation |
| tr/tf | 26 ns / 23 ns - rise/fall times at VDD = 50 V, ID = 5.2 A, RG = 53 Ω - sets minimum practical switching period |
Pinout & Package
IRFR120ZTR uses the D-Pak (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection. The package measures 6.73 mm × 6.22 mm × 2.39 mm and is lead-free (PbF) compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Low-side reference node; connects to ground or low-side switch node; carries full load current |
| Pin 2 (Gate) | Control input (G) | High-impedance MOSFET gate; requires <10 nC charge for full turn-on; sensitive to ESD |
| Pin 3 (Drain) | Drain terminal (D) | High-side power node; electrically and thermally connected to exposed metal tab; must be isolated from other layers |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 190 mΩ max at 10 V drive - reduces conduction loss by >30% vs. legacy 100 V MOSFETs in same package |
| 175°C operating junction temperature | Enables operation in sealed enclosures or high-ambient environments without derating |
| Repetitive avalanche rated | Tested to 18 mJ single-pulse and validated for repetitive operation within thermal limits |
| Fast switching with low Qgd | Qgd = 3.1 nC - minimizes Miller plateau time and improves dV/dt immunity |
| Optimized body diode | trr = 24–36 ns, Qrr = 23–35 nC - lowers switching loss during commutation in half-bridge configurations |
Applications
| DC-DC Buck Converter | Brushed DC Motor Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP10NK100ZFP | 100 V, 10 A, RDS(on) = 220 mΩ, TO-220FP package, no avalanche rating specified | Through-hole mounting only; higher RDS(on) increases conduction loss by ~16% | Prefer when through-hole assembly is required and avalanche robustness is not critical |
| IXTP10N100D2 | 100 V, 10 A, RDS(on) = 200 mΩ, TO-220 package, 100% avalanche tested to 20 mJ | Larger footprint and higher RθJA; requires heatsink for >5 A continuous | Choose when higher avalanche margin is needed and board space allows TO-220 |
Compared with STP10NK100ZFP and IXTP10N100D2, IRFR120ZTR offers superior thermal performance in surface-mount form factor, lower gate charge for faster switching, and proven repetitive avalanche capability-making it optimal for space-constrained, high-reliability industrial power stages.

FAQ
What is the maximum continuous drain current for IRFR120ZTR at 100°C case temperature?
The maximum continuous drain current is 6.1 A at TC = 100°C and VGS = 10 V, as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced heat transfer at elevated case temperatures and must be verified against actual PCB layout and ambient conditions.
Does IRFR120ZTR require a gate resistor for reliable switching?
Yes-a gate resistor (typically 5–53 Ω) is required to control dI/dt and suppress ringing caused by gate loop inductance and MOSFET capacitance. The datasheet specifies switching times using RG = 53 Ω; lower values reduce switching time but increase EMI and gate driver stress.
Can IRFR120ZTR be used in avalanche mode repeatedly?
Yes-IRFR120ZTR is explicitly tested and rated for repetitive avalanche operation, provided junction temperature remains ≤175°C and single-pulse energy does not exceed 18 mJ. Safe operation requires transient thermal impedance analysis per Figure 11 and avalanche curves in Figures 15–16.
Is the drain tab electrically isolated from the PCB in D-Pak mounting?
No-the drain (Pin 3) is internally connected to the exposed metal tab, which serves as both thermal path and electrical node. When mounted on PCB, the tab must be routed to drain potential and isolated from ground or other signals using solder mask clearance and appropriate creepage/clearance design.
