Product details

Overview

IRFZ14STRLPBF 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, motor drives, and power supply switching stages.

For engineers reviewing the IRFZ14STRLPBF datasheet, IRFZ14STRLPBF pinout, IRFZ14STRLPBF application, or IRFZ14STRLPBF equivalent, key selection criteria include its low on-resistance under 10 V gate drive, fast switching performance (10 ns turn-on delay, 19 ns fall time), avalanche energy rating (47 mJ), thermal robustness, and D2PAK PCB-mount power dissipation capability (3.7 W).

Technical Context

This third-generation power MOSFET employs advanced silicon processing to minimize R_DS(on) per die area while maintaining rugged unclamped inductive switching capability. Its gate threshold voltage (2.0–4.0 V) supports standard logic-level drive, and its body diode exhibits 70–140 ns reverse recovery time with 200–400 μC Q_rr.

The device operates within -55 °C to +175 °C junction range and delivers 43 W maximum power dissipation at T_C = 25 °C. Thermal resistance from junction-to-case is 3.5 °C/W, enabling effective heatsinking via the exposed drain pad in D2PAK mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage suitable for 48 V bus and industrial power rails
R_DS(on) @ V_GS = 10 V	0.20 Ω - Enables <1.2 W conduction loss at 6 A continuous drain current
Q_g (total)	11 nC - Low gate charge reduces driver power demand and switching losses in high-frequency operation
I_D (continuous, T_C = 25 °C)	10 A - Supports medium-power load switching without forced air cooling
E_AS	47 mJ - Rated single-pulse avalanche energy allows reliable operation under inductive turn-off stress
T_J max	+175 °C - Enables use in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures
R_thJC	3.5 °C/W - Efficient thermal path from die to heatsink via D2PAK drain tab

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 V_DS, 10 A, R_DS(on) = 0.75 Ω - higher voltage rating but 3.75× higher on-resistance	Better suited for universal-input PFC or flyback primary side; not optimal for low-voltage, high-current switching	Select when >400 V blocking is required; avoid for 48 V systems where conduction loss dominates
IRFZ44NPBF	55 V V_DS, 49 A, R_DS(on) = 0.028 Ω - higher current, lower R_DS(on), TO-220 package	Requires through-hole assembly and larger heatsink; unsuitable for space-constrained SMT designs	Choose for higher-current, lower-loss needs where D2PAK footprint and reflow compatibility are not mandatory

Compared with STP10NK60ZFP and IRFZ44NPBF, the IRFZ14STRLPBF offers the optimal balance of 60 V rating, D2PAK SMT compatibility, 0.20 Ω on-resistance, and 10 A continuous current - making it uniquely suited for compact, medium-power industrial and telecom power stages where board space and thermal management are co-constrained.

FAQ

What is the maximum continuous drain current for IRFZ14STRLPBF at 100 °C case temperature?

The IRFZ14STRLPBF supports 7.2 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package and must be verified against actual PCB layout and heatsinking. The full 10 A rating applies only at T_C = 25 °C. Designers should consult Fig. 9 (Maximum Drain Current vs. Case Temperature) in the IRFZ14STRLPBF datasheet for precise derating curves.

Does IRFZ14STRLPBF have a built-in body diode, and what are its key parameters?

Yes, the IRFZ14STRLPBF integrates a parasitic body diode inherent to its vertical N-channel MOSFET structure. Key parameters include 10 A continuous forward current (I_S), 40 A pulsed rating (I_SM), 1.6 V forward voltage (V_SD) at 10 A and 25 °C, and 70–140 ns reverse recovery time (t_rr). These values are confirmed in the "Drain-Source Body Diode Characteristics" section of the IRFZ14STRLPBF datasheet.

Is IRFZ14STRLPBF RoHS-compliant and halogen-free?

Yes, IRFZ14STRLPBF is RoHS-compliant and halogen-free, as indicated by the "-TRLPbF" suffix and confirmed in Vishay's ordering information table. It meets JEDEC J-STD-609A Class 1 for moisture sensitivity and complies with EU Directive 2011/65/EU. Full compliance documentation, including material declarations, is available via Vishay's website using document number 90365.

What is the gate threshold voltage range for IRFZ14STRLPBF, and how does it affect drive requirements?

The IRFZ14STRLPBF has a gate threshold voltage (V_GS(th)) range of 2.0 V to 4.0 V at I_D = 250 μA, per the Specifications table. This allows reliable enhancement with standard 5 V or 3.3 V logic-level drivers, though full R_DS(on) performance requires V_GS ≥ 10 V. The relatively wide threshold window necessitates careful gate drive design to ensure consistent turn-on across temperature and unit variation.

Can IRFZ14STRLPBF be used in avalanche-mode operation, and what is its rated energy?

Yes, the IRFZ14STRLPBF is rated for single-pulse avalanche operation with E_AS = 47 mJ under defined test conditions (V_DD = 25 V, I_AS = 10 A, T_J = 25 °C). This rating is validated per Fig. 12 and Table 1 in the IRFZ14STRLPBF datasheet. Repetitive avalanche is not guaranteed and requires system-level validation of pulse width, duty cycle, and thermal limits.
