Product details

Overview

IRLZ24LPBF from Vishay Siliconix is a logic-level N-channel power MOSFET in I2PAK (TO-262) package, rated for 60 V V_DS, 17 A continuous drain current at T_C = 25 °C, and 0.10 Ω R_DS(on) at V_GS = 5 V. It operates up to 175 °C junction temperature and supports fast switching in DC-DC converters and motor control circuits.

For engineers reviewing the IRLZ24LPBF datasheet, IRLZ24LPBF pinout, IRLZ24LPBF application, or IRLZ24LPBF equivalent, key selection criteria include its logic-level gate drive compatibility with 4–5 V microcontrollers, low on-resistance enabling high-efficiency 12–24 V load switching, and rugged unclamped avalanche capability (E_AS = 110 mJ) for inductive load handling.

Technical Context

This MOSFET uses third-generation trench-gate silicon technology optimized for low R_DS(on) and fast switching with minimal gate charge (Q_g = 18 nC). Its dynamic dV/dt rating (4.5 V/ns) and body diode recovery time (t_rr = 110–260 ns) support reliable operation in hard-switched topologies.

The device integrates a monolithic body diode with V_SD = 1.5 V at 17 A and Q_rr = 0.49–1.5 μC, enabling synchronous rectification and freewheeling in buck converters and H-bridge motor drivers without external diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Supports 24 V industrial bus and 48 V telecom input rails with margin.
R_DS(on) @ V_GS = 5 V	0.10 Ω - Enables <1.7 W conduction loss at 17 A, reducing heatsink requirements.
Q_g	18 nC - Allows efficient 100–500 kHz PWM switching with standard gate drivers (e.g., TC4420).
I_D (continuous)	17 A @ T_C = 25 °C - Delivers high current in PCB-mounted thermal designs using 1" FR-4 copper area.
E_AS	110 mJ - Withstands repetitive inductive energy spikes in relay/motor coil snubbing without failure.
T_J max	175 °C - Ensures reliability in sealed enclosures or high-ambient environments (e.g., automotive under-hood).
dV/dt rating	4.5 V/ns - Resists false turn-on during high-slew-rate noise transients in motor drives.

Pinout & Package

I2PAK (TO-262) surface-mount package with isolated drain tab for direct PCB thermal coupling; 3-pin configuration (G, D, S), lead (Pb)-free and halogen-free per IEC 61249-2-21.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Logic-level compatible: fully enhanced at V_GS = 4–5 V; requires ≤18 nC charge for full turn-on.
D (Drain)	High-side power output	Internally connected to exposed metal tab; must be thermally anchored to large copper pour for 60 W dissipation.
S (Source)	Power return reference	Common node for gate drive return and current sensing; low-inductance layout critical for EMI control.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced from 4 V V_GS, eliminating need for level-shifting circuitry with 3.3 V/5 V MCUs.
Ruggedized avalanche rating	Guaranteed 110 mJ single-pulse avalanche energy enables robustness in inductive switching without external clamps.
Low R_DS(on) at low V_GS	0.14 Ω at V_GS = 4 V ensures stable on-state performance across wide supply voltage tolerances.
Fast body diode recovery	t_rr = 110 ns (typ.) minimizes reverse recovery losses in synchronous rectifier and half-bridge applications.
175 °C operation	Extended thermal range allows use in high-temperature environments where standard MOSFETs derate significantly.

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
IRFZ24NPBF	Higher R_DS(on) (0.07 Ω @ 10 V), non-logic-level (V_GS(th) = 2–4 V), TO-220 package	Requires 10 V gate drive; unsuitable for 3.3 V MCU direct drive	Select only when gate drive ≥8 V is available and through-hole mounting is preferred.
STP16NF06L	60 V, 16 A, R_DS(on) = 0.07 Ω @ 10 V, logic-level but higher Q_g (25 nC), TO-220FP	Slower switching due to higher gate charge; lower thermal performance in surface-mount layouts	Prefer for cost-sensitive through-hole designs where switching frequency <100 kHz.

Compared with IRLZ24LPBF, IRFZ24NPBF demands higher gate voltage and lacks guaranteed logic-level operation, while STP16NF06L trades faster switching for higher gate drive power and inferior thermal resistance in SMT applications.

FAQ

What is the maximum continuous drain current for IRLZ24LPBF at 100 °C case temperature?

The IRLZ24LPBF supports 12 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the I2PAK package mounted on standard PCB; actual current depends on heatsinking and ambient conditions. The IRLZ24LPBF maintains safe operation up to 175 °C junction temperature, making it suitable for high-temperature industrial environments.

Does IRLZ24LPBF require a gate resistor for typical 5 V MCU drive?

Yes, a gate resistor (typically 10–47 Ω) is recommended with IRLZ24LPBF when driven by a 5 V MCU to control dv/dt, suppress ringing, and limit peak gate current. Although the IRLZ24LPBF has low total gate charge (18 nC), fast edge rates can cause EMI and shoot-through in bridge configurations. The resistor value balances switching speed against noise and driver stress - the IRLZ24LPBF datasheet confirms stable operation with R_g = 9 Ω in switching time tests.

Can IRLZ24LPBF replace IRLZ24N in an existing design?

No - IRLZ24LPBF and IRLZ24N are not interchangeable. IRLZ24N uses TO-220 package and has different thermal characteristics and pinout. The IRLZ24LPBF is I2PAK (TO-262) with drain-connected tab, while IRLZ24N is through-hole TO-220. Substituting IRLZ24LPBF would require PCB redesign, new thermal layout, and verification of gate drive timing due to differing parasitic inductance. Always consult the respective datasheets before replacement.

What is the body diode forward voltage of IRLZ24LPBF at 17 A?

The body diode forward voltage (V_SD) of IRLZ24LPBF is 1.5 V maximum at T_J = 25 °C and I_S = 17 A with V_GS = 0 V. This value increases with junction temperature - at 125 °C, V_SD rises to approximately 1.3 V (typical). The IRLZ24LPBF body diode is integral to the MOSFET die and supports freewheeling in inductive loads without external components.

Is IRLZ24LPBF RoHS compliant and halogen-free?

Yes, IRLZ24LPBF is both RoHS-compliant (per Directive 2002/95/EC) and halogen-free according to IEC 61249-2-21. The "PbF" suffix denotes lead (Pb)-free terminations, and the device meets Vishay's green initiative standards. Full compliance documentation, including material declarations and test reports, is available via Vishay's website using document number 90416.
