Product details
Overview
IRFZ14L from Vishay Siliconix is a 60 V, 10 A N-channel power MOSFET in I2PAK (TO-262) through-hole package, optimized for low-profile high-current switching in DC-DC converters, motor drivers, and power supplies. It delivers RDS(on) = 0.20 Ω at VGS = 10 V, supports 175 °C junction operation, and features fast switching with 11 nC total gate charge.
For engineers reviewing the IRFZ14L datasheet, IRFZ14L pinout, IRFZ14L application, or IRFZ14L equivalent, this page provides verified package mapping, validated thermal and dynamic parameters, confirmed body diode recovery performance (trr = 70–140 ns), and real-world selection guidance for industrial power stage design.
Technical Context
The IRFZ14L employs third-generation silicon process technology to achieve low on-resistance per die area while maintaining rugged avalanche capability (EAS = 47 mJ). Its gate threshold voltage (VGS(th) = 2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drive, and its 3.1 nC gate-source charge enables efficient control with minimal driver loss.
Thermal design is supported by RthJC = 3.5 °C/W (junction-to-case) and RthJA = 40 °C/W (PCB mount), enabling stable operation up to 175 °C. The integrated body diode exhibits VSD = 1.6 V at 10 A and controlled reverse recovery (Qrr = 200–400 μC), critical for synchronous rectification and inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum blocking voltage for 48 V bus systems with margin against transients |
| RDS(on) @ VGS = 10 V | 0.20 Ω - Enables ≤2 W conduction loss at 10 A continuous drain current |
| ID (continuous, TC = 25 °C) | 10 A - Sustains full-rated current with heatsink or PCB copper area |
| Qg (total) | 11 nC - Determines gate driver power requirement and switching speed in hard-switched topologies |
| trr (body diode) | 70–140 ns - Limits reverse recovery losses during commutation in buck or half-bridge circuits |
| PD (TC = 25 °C) | 43 W - Specifies maximum dissipation with case temperature maintained at 25 °C |
| TJ max | 175 °C - Allows operation in high-ambient environments such as enclosed industrial enclosures |

IC Role / Device Role / Timing Role: Main power switch controlling duty cycle via PWM; handles both conduction and switching phases. Use Value: RDS(on) = 0.20 Ω minimizes I²R losses at full load, while trr < 140 ns prevents shoot-through in synchronous configurations. |
Use Scenario: H-bridge driver for 24 V brushed motors in industrial actuators or HVAC dampers. IC Role / Device Role / Timing Role: Low-side or high-side switching element; operates in linear or saturated mode depending on control strategy. Use Value: 10 A continuous rating supports peak stall currents; 175 °C rating accommodates intermittent overload without thermal shutdown. |
| AC-DC Auxiliary Power Supply | Industrial Relay/Solenoid Driver |
Use Scenario: Off-line flyback auxiliary supply powering control circuitry in industrial PLCs. IC Role / Device Role / Timing Role: Primary-side switch operating at 65–100 kHz; subjected to repetitive voltage spikes and thermal cycling. Use Value: EAS = 47 mJ allows safe clamping of transformer leakage energy without external TVS, reducing BOM count. |
Use Scenario: Solid-state replacement for electromechanical relays driving 24 V/5 A solenoids in factory automation. IC Role / Device Role / Timing Role: Unclamped inductive load switch; must absorb stored magnetic energy during turn-off. Use Value: Avalanche-rated operation eliminates need for freewheeling diode in cost-sensitive designs where layout space is limited. |
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 |
|---|---|---|---|
| IRFZ24L | RDS(on) = 0.07 Ω @ 10 V (lower), ID = 17 A (higher), same I2PAK package | Better conduction efficiency at >5 A; higher gate charge (24 nC) increases driver demand | Select when lower RDS(on) justifies increased gate drive complexity and cost |
| STP10NK60ZFP | 600 V VDS, RDS(on) = 0.73 Ω @ 10 V, TO-220FP package, Zener-protected gate | Higher voltage rating suits universal input AC-DC; higher RDS(on) limits use to <3 A continuous | Choose for mains-referenced primary switches where 60 V rating is insufficient |
Compared with IRFZ14L, IRFZ24L offers significantly lower conduction loss but demands more gate drive energy, while STP10NK60ZFP trades voltage headroom and ruggedness for reduced system-level transient protection requirements - neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum continuous drain current for IRFZ14L at 100 °C case temperature?
The IRFZ14L supports 7.2 A continuous drain current at TC = 100 °C, reflecting its linear derating factor of 0.29 W/°C from the 43 W maximum power dissipation at 25 °C. This value is confirmed in the Absolute Maximum Ratings table of Vishay document 90365 and applies under steady-state thermal conditions with adequate PCB copper or heatsinking. Designers must verify actual case temperature in situ using thermal simulation or measurement before finalizing layout for IRFZ14L.
Does IRFZ14L have avalanche energy rating, and how is it specified?
Yes, IRFZ14L is rated for single-pulse unclamped inductive switching with EAS = 47 mJ, measured under VDD = 25 V, starting TJ = 25 °C, L = 548 μH, Rg = 25 Ω, and IAS = 10 A per Figure 12 in the datasheet. This rating validates safe operation during inductive turn-off without external snubbers in applications like solenoid or relay driving. The IRFZ14L datasheet does not specify repetitive avalanche capability, so repeated inductive switching must remain within SOA limits.
What is the gate threshold voltage range for IRFZ14L, and how does it affect drive compatibility?
The gate threshold voltage VGS(th) for IRFZ14L is specified as 2.0–4.0 V at ID = 250 μA, meaning it reliably turns on with standard 5 V logic-level signals but achieves full enhancement only above ~10 V. At VGS = 10 V, RDS(on) reaches its rated 0.20 Ω. Using 5 V drive yields higher on-resistance (~0.45 Ω typical), increasing conduction loss - thus IRFZ14L is best paired with 10 V gate drivers in high-efficiency designs.
Is IRFZ14L RoHS-compliant, and what packaging options are available?
IRFZ14L is offered in lead (Pb)-free and halogen-free versions (e.g., SiHFZ14L-GE3) per Vishay's material categorization policy. The "-GE3" suffix indicates RoHS-compliant, matte tin-plated leads and green molding compound. Legacy Pb-bearing variants (e.g., IRFZ14LPbF) are discontinued per EU RoHS Directive. All IRFZ14L ordering codes comply with JEDEC standards for I2PAK (TO-262) mechanical and thermal specifications.
How does the body diode performance of IRFZ14L compare to discrete Schottky diodes in freewheeling applications?
The IRFZ14L body diode has VSD = 1.6 V at 10 A and trr = 70–140 ns, making it suitable for low-frequency (<50 kHz) freewheeling where Schottky diode cost or layout area is prohibitive. However, its forward voltage is higher than typical 0.4–0.6 V Schottky devices, increasing conduction loss. For high-frequency or high-efficiency designs, an external Schottky remains preferable - the IRFZ14L body diode serves best as a rugged, integrated backup rather than primary rectifier.
