Product details

Overview

IRFZ14STRR from Vishay Siliconix is a 60 V, 10 A N-channel surface-mount power MOSFET in D2PAK (TO-263) package, featuring 0.20 Ω R_DS(on) at V_GS = 10 V, 11 nC total gate charge, and 175 °C maximum junction temperature - designed for high-efficiency DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRFZ14STRR datasheet, IRFZ14STRR pinout, IRFZ14STRR application, or IRFZ14STRR equivalent, this part supports fast-switching, high-current switching in compact PCB layouts where thermal robustness and avalanche energy rating (47 mJ) are critical selection criteria.

Technical Context

This MOSFET employs third-generation silicon process technology to minimize on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its gate threshold voltage range (2.0–4.0 V) ensures compatibility with standard 5 V and 10 V logic-level drivers.

The device integrates a fast-recovery body diode (t_rr = 70–140 ns, Q_rr = 200–400 μC) and exhibits low output capacitance (C_oss = 160 pF) and reverse transfer capacitance (C_rss = 29 pF), enabling efficient high-frequency operation up to several hundred kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 48 V bus systems with 20 % margin against transients
R_DS(on) @ V_GS = 10 V	0.20 Ω - enables ≤1.2 W conduction loss at 7.2 A continuous current
Q_g max	11 nC - determines gate drive power requirement and switching speed scalability
I_D continuous @ T_C = 100 °C	7.2 A - defines usable current in thermally constrained surface-mount applications
E_AS	47 mJ - quantifies single-pulse avalanche robustness during inductive turn-off
t_r/t_f	50 ns / 19 ns - enables <500 kHz PWM operation with minimal switching loss
T_J max	175 °C - allows operation in high-ambient industrial environments without derating

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for thermal conduction and mechanical anchoring. Standard 3-pin configuration: Gate (pin 1), Drain (tab/thermal pad), Source (pins 2 & 3 tied internally).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal requiring ≤±20 V drive; 3.1 nC Q_gs sets Miller plateau duration
Tab (Drain)	Drain	High-current output node and primary thermal path; electrically connected to PCB copper pour
Pins 2 & 3	Source	Power return and reference for gate drive; dual pins reduce bond-wire inductance and improve current sharing

Key Features

Feature	Design Value
Low R_DS(on) per area	Enables smaller die size or higher current density vs. prior-gen MOSFETs at same voltage rating
Fast switching with low Q_gd/Q_g ratio	5.8 nC / 11 nC = 53 % - reduces Miller-induced switching delay and improves hard-switching efficiency
175 °C rated junction	Supports extended lifetime in sealed enclosures or high-ambient automotive under-hood zones
47 mJ unclamped avalanche energy	Allows safe operation in inductive loads without external snubbers in moderate-energy circuits
Body diode t_rr < 140 ns	Minimizes reverse recovery losses in synchronous rectification and H-bridge freewheeling

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
STP10NK60ZFP	600 V rating, 0.72 Ω R_DS(on), TO-220FP package	Designed for high-voltage PFC and SMPS primary side, not low-voltage switching	Select only when 600 V blocking and through-hole mounting are required
IRFZ44NPBF	55 V V_DS, 0.028 Ω R_DS(on), TO-220 package, higher current (49 A)	Higher conduction efficiency but larger footprint and lower thermal resistance via heatsink	Prefer for high-current, heatsink-mounted designs where board space permits

Compared with STP10NK60ZFP and IRFZ44NPBF, IRFZ14STRR offers optimal balance of 60 V rating, D2PAK thermal performance, and gate drive compatibility for space-constrained 48 V system switches - neither a direct replacement nor functionally identical, but a targeted solution for surface-mount medium-power switching.

FAQ

What is the maximum continuous drain current for IRFZ14STRR at 100 °C case temperature?

The IRFZ14STRR supports 7.2 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced heat dissipation at elevated temperatures and must be validated against actual PCB layout and airflow conditions in the target application.

Does IRFZ14STRR have a built-in body diode, and what are its key parameters?

Yes, IRFZ14STRR integrates a parasitic body diode inherent to its N-channel MOSFET structure. Key parameters include 10 A continuous source-drain current, 40 A pulsed rating, 1.6 V forward voltage at 10 A and 25 °C, and reverse recovery time of 70–140 ns - critical for freewheeling and synchronous rectification behavior.

Is IRFZ14STRR RoHS-compliant and halogen-free?

Yes, IRFZ14STRR is lead (Pb)-free and halogen-free, conforming to Vishay's "GE3" material categorization. The part meets RoHS Directive 2011/65/EU and is marked accordingly in Vishay's ordering information tables - no Pb in terminations or packaging materials.

What is the thermal resistance from junction to case (R_thJC) for IRFZ14STRR?

The maximum junction-to-case (drain) thermal resistance R_thJC for IRFZ14STRR is 3.5 °C/W, measured from the silicon die to the D2PAK drain tab. This value assumes proper soldering to a minimum 1" × 1" FR-4 PCB copper pour and is essential for calculating worst-case junction temperature under load.

Can IRFZ14STRR be used as a direct replacement for IRFZ44N in existing designs?

No, IRFZ14STRR is not a direct replacement for IRFZ44N: it has higher R_DS(on) (0.20 Ω vs. 0.028 Ω), lower current rating (10 A vs. 49 A), and D2PAK instead of TO-220 package. While both are 60 V N-channel MOSFETs, IRFZ14STRR targets surface-mount space savings over raw current capacity - redesign of gate drive, thermal layout, and current handling is required.
