Product details

Overview

IRLZ14STRR from Vishay Siliconix is a logic-level N-channel 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 8.4 nC total gate charge and supports high-temperature operation up to +175 °C junction temperature, making it suitable for DC-DC synchronous rectification and motor drive half-bridge legs.

For engineers reviewing the IRLZ14STRR datasheet, IRLZ14STRR pinout, IRLZ14STRR application, or IRLZ14STRR equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 5 V, avalanche energy rating of 68 mJ, and surface-mount D2PAK thermal performance (R_thJC = 3.5 °C/W).

Technical Context

This MOSFET uses Vishay's third-generation silicon process to achieve low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its gate threshold voltage range (1.0–2.0 V) ensures reliable turn-on with standard 3.3 V or 5 V logic controllers without external level shifting.

The device integrates a fast-recovery body diode (t_rr = 93–130 ns, Q_rr = 340–650 nC) and exhibits low output capacitance (C_oss = 170 pF) and reverse transfer capacitance (C_rss = 42 pF), supporting high-frequency hard-switching topologies up to several hundred kHz.

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
IRLZ44NTRR	R_DS(on) = 0.028 Ω @ 5 V (lower), but V_DS = 55 V (lower); Q_g = 71 nC (much higher)	Better conduction loss at low voltage, but slower switching and lower voltage margin	Prefer IRLZ14STRR where 60 V rating and fast switching dominate; choose IRLZ44NTRR only if ultra-low R_DS(on) at ≤40 V is critical
STP16NF06LT4	V_DS = 60 V (same), R_DS(on) = 0.12 Ω @ 10 V (not logic-level), V_GS(th) = 2–4 V (higher threshold)	Requires 10 V gate drive; unsuitable for 3.3 V logic interfaces without buffer	Select IRLZ14STRR when logic-level compatibility with 3.3 V/5 V controllers is mandatory; STP16NF06LT4 suits 12 V gate drive systems

Compared with IRLZ44NTRR and STP16NF06LT4, the IRLZ14STRR uniquely balances 60 V rating, true logic-level gate drive (1.0–2.0 V), low Q_g, and fast body diode-making it optimal for space-constrained, thermally demanding, and low-voltage-control applications where both efficiency and drive simplicity matter.

FAQ

What is the maximum continuous drain current rating for IRLZ14STRR at 100 °C case temperature?

The IRLZ14STRR supports 7.2 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the D2PAK package and ensures safe operation under sustained high-temperature conditions without exceeding the 175 °C maximum junction temperature. The linear derating factor is 0.29 W/°C above 25 °C case temperature.

Does IRLZ14STRR have a built-in body diode, and what are its key recovery characteristics?

Yes, the IRLZ14STRR integrates a monolithic body diode with t_rr = 93–130 ns and Q_rr = 340–650 nC at T_J = 25 °C, IF = 10 A, and di/dt = 100 A/μs. These values are measured under standardized test conditions and confirm suitability for synchronous rectification and freewheeling in hard-switched topologies. The diode's forward voltage is 1.6 V at 10 A and 25 °C.

Is IRLZ14STRR compatible with 3.3 V microcontroller GPIOs for direct gate driving?

Yes, the IRLZ14STRR has a gate threshold voltage range of 1.0–2.0 V and achieves full enhancement at V_GS = 5 V, making it fully compatible with 3.3 V logic outputs. At V_GS = 3.3 V, R_DS(on) rises to approximately 0.28 Ω (per datasheet), which remains usable for moderate-current applications; for lowest losses, 5 V drive is recommended.

What is the thermal resistance from junction to case (R_thJC) for IRLZ14STRR, and how does it impact heatsink design?

The IRLZ14STRR has a maximum junction-to-case thermal resistance (R_thJC) of 3.5 °C/W. This low value means that with a 100 °C temperature rise from junction to case, the device can dissipate up to ~28.6 W continuously. In practice, effective PCB copper area under the exposed drain pad replaces or supplements traditional heatsinks-no external heatsink is required for ≤15 W dissipation in typical FR-4 layouts.

How does the avalanche energy rating of IRLZ14STRR support reliability in inductive load switching?

The IRLZ14STRR is rated for 68 mJ single-pulse avalanche energy (E_AS) under defined test conditions (V_DD = 25 V, L = 790 μH, I_AS = 10 A). This specification validates its ability to absorb inductive energy during unclamped inductive switching events-such as motor phase commutation or relay de-energization-without failure, enhancing system robustness in real-world industrial and automotive applications.
