Product details

Overview

IRLZ14SPBF from Vishay Siliconix is a logic-level N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, rated for 60 V V_DS, 10 A continuous drain current at T_C = 25 °C, and 0.20 Ω R_DS(on) at V_GS = 5 V. It delivers fast switching with 9.3 ns turn-on delay and supports high-reliability motor control and DC-DC converter applications up to 175 °C junction temperature.

For engineers reviewing the IRLZ14SPBF datasheet, IRLZ14SPBF pinout, IRLZ14SPBF application, or IRLZ14SPBF equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), low Q_g (8.4 nC), rugged unclamped avalanche capability (68 mJ), and surface-mount D2PAK thermal performance (R_thJC = 3.5 °C/W).

Technical Context

This MOSFET employs Vishay's third-generation silicon process to achieve ultra-low on-resistance per die area while maintaining robust safe operating area (SOA) and fast body diode recovery (t_rr = 93–130 ns). Its gate charge profile (Q_gs = 3.5 nC, Q_gd = 6.0 nC) enables efficient PWM operation in synchronous buck and half-bridge topologies.

The device integrates an intrinsic source-drain body diode with V_SD = 1.6 V at I_S = 10 A and exhibits controlled dv/dt immunity (4.5 V/ns peak) for reliable commutation in inductive loads. Thermal design leverages the D2PAK's low junction-to-case resistance and 2.0 W typical surface-mount power dissipation capability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage for 48 V rail systems with margin
R_DS(on) @ V_GS = 5 V	0.20 Ω - Enables <1.2 W conduction loss at 6 A DC load current
Q_g	8.4 nC - Low gate charge reduces driver power and switching losses
I_D (continuous, T_C = 25 °C)	10 A - Supports high-current motor gate drivers and power supplies
t_r / t_f	110 ns / 26 ns - Fast edge rates minimize transition-time losses in hard-switched converters
E_AS	68 mJ - Withstands unclamped inductive energy in relay/snubberless designs
T_J max	+175 °C - Enables operation in sealed enclosures or high-ambient industrial environments

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection. Standard 3-pin configuration: Gate (G), Drain (D), Source (S). Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Logic-compatible input requiring only 5 V to fully enhance; V_GS(th) range 1.0–2.0 V ensures reliable turn-on with microcontroller GPIO
Drain (D)	High-side power terminal	Connected to PCB thermal pad; carries full load current and dissipates heat directly to copper plane (R_thJC = 3.5 °C/W)
Source (S)	Reference/return path	Low-inductance return node; internal source inductance LS = 7.5 nH minimizes ringing during fast switching

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at 5 V V_GS, eliminating need for gate boosters in 3.3 V/5 V MCU-controlled systems
Rugged avalanche rating	68 mJ single-pulse E_AS allows reliable operation without external snubbers in inductive switching circuits
Fast body diode recovery	t_rr = 93–130 ns and Q_rr = 340–650 nC reduce cross-conduction losses in synchronous rectification
Surface-mount D2PAK	Enables high-power density layout with 43 W P_D capability and optimized thermal path to PCB
175 °C junction rating	Supports extended lifetime in thermally constrained industrial and automotive under-hood applications

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
IRFZ44NPBF	Higher V_GS(th) (2–4 V), higher R_DS(on) (0.028 Ω @ 10 V), requires 10 V gate drive	Not logic-level; unsuitable for direct 3.3 V/5 V MCU drive without level shift	Select when higher V_DS margin (55 V) and lower R_DS(on) at 10 V are prioritized over gate drive simplicity
STP16NF06L	Lower V_DS (60 V same), slightly higher R_DS(on) (0.22 Ω @ 5 V), similar Q_g (9.5 nC)	Compatible logic-level operation but lower avalanche rating (E_AS = 45 mJ)	Choose when STMicroelectronics supply chain alignment or alternate qualification is required

Compared with IRLZ14SPBF, IRFZ44NPBF demands higher gate voltage and offers better conduction efficiency only with 10 V drive, while STP16NF06L matches logic-level usability but provides less robust avalanche tolerance-making IRLZ14SPBF optimal for space-constrained, thermally demanding, and inductive-load applications needing guaranteed 5 V turn-on.

FAQ

What is the maximum continuous drain current for IRLZ14SPBF at 100 °C case temperature?

The IRLZ14SPBF 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 validated against actual board layout and airflow conditions. The IRLZ14SPBF maintains stable R_DS(on) up to 175 °C junction temperature, enabling operation in high-ambient environments when properly heatsinked.

Does IRLZ14SPBF require a gate resistor for safe switching?

Yes, a gate resistor is recommended for IRLZ14SPBF to control dV/dt and prevent oscillation during switching. Typical values range from 10 Ω to 25 Ω depending on drive strength and layout parasitics. The IRLZ14SPBF datasheet specifies test conditions using R_g = 12 Ω for switching time measurements, and its low Q_g (8.4 nC) allows use of small, cost-effective resistors without compromising speed.

Can IRLZ14SPBF be used in avalanche mode repeatedly?

No-IRLZ14SPBF is rated for single-pulse avalanche energy (E_AS = 68 mJ), not repetitive avalanche. The datasheet explicitly defines this as a "single pulse" rating limited by maximum junction temperature. Repeated avalanche operation risks cumulative thermal stress and premature failure. For circuits subject to frequent inductive transients, external clamping or snubbing is advised alongside IRLZ14SPBF use.

What is the body diode forward voltage of IRLZ14SPBF at 10 A?

The body diode forward voltage (V_SD) of IRLZ14SPBF is 1.6 V at I_S = 10 A, T_J = 25 °C, and V_GS = 0 V. This value increases with temperature and current; at 150 °C junction temperature, V_SD remains below 2.0 V. The IRLZ14SPBF body diode exhibits fast recovery (t_rr = 93–130 ns), making it suitable for freewheeling in synchronous rectifier and H-bridge configurations.

Is IRLZ14SPBF RoHS-compliant and halogen-free?

Yes, IRLZ14SPBF is lead (Pb)-free and halogen-free, meeting RoHS Directive 2011/65/EU requirements. The "PbF" suffix denotes lead-free termination, and material compliance is confirmed in Vishay's documentation (e.g., Doc. #99912). The IRLZ14SPBF is also compliant with JEDEC standards for moisture sensitivity level (MSL) and soldering profiles, including peak reflow temperature of 300 °C for 10 seconds.
