Product details

Overview

IRF530L from Vishay Siliconix is a 100 V, 14 A N-channel power MOSFET in TO-220AB package, optimized for hard-switched DC-DC converters and motor control circuits requiring rugged avalanche capability and fast switching. It delivers R_DS(on) = 0.16 Ω at V_GS = 10 V, Q_g = 26 nC, and operates up to +175 °C junction temperature.

For engineers reviewing the IRF530L datasheet, IRF530L pinout, IRF530L application, or IRF530L equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts with documented parameter and application differences.

Technical Context

The IRF530L uses a third-generation planar vertical DMOS structure enabling low conduction loss and high dV/dt immunity. Its gate threshold voltage (2.0–4.0 V) supports standard logic-level drive, while its 69 mJ single-pulse avalanche energy rating ensures robustness under inductive load turn-off stress.

Thermal design is enabled by R_thJC = 1.7 °C/W and R_thCS = 0.50 °C/W, allowing efficient heatsinking. The device integrates a body diode with t_rr = 150–280 ns and Q_rr = 0.85–1.7 μC, suitable for freewheeling in non-synchronous buck topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Supports 48 V bus systems with ≥2× safety margin against transients
R_DS(on) @ V_GS = 10 V	0.16 Ω - Enables ≤2.2 W conduction loss at 14 A continuous drain current
Q_g	26 nC - Determines gate drive power requirement (~130 µW per MHz at 5 V swing)
I_D (T_C = 25 °C)	14 A - Sustains full-load current in 50 W-class power stages without derating
E_AS	69 mJ - Absorbs unclamped inductive energy in motor drive or relay snubbing
T_J max	+175 °C - Allows operation in sealed industrial enclosures without active cooling
Body diode V_SD	2.5 V @ I_S = 14 A - Limits freewheeling loss but requires external Schottky for high-efficiency sync rectification

Pinout & Package

IRF530L is housed in a through-hole TO-220AB package with isolated tab (drain-connected), standardized for mechanical mounting and thermal interface to heatsinks. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control input	Accepts 0–10 V logic-level signals; 5.5 nC Q_gs enables fast turn-on with low-current drivers
Drain (D)	High-side switch node	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits
Source (S)	Power return path	Reference point for gate drive; carries full load current and body diode reverse recovery charge (Q_rr)

Key Features

Feature	Design Value
Repetitive avalanche rated	Withstands 14 A repetitive avalanche current (I_AR) and 8.8 mJ energy (E_AR) without degradation
Dynamic dV/dt immunity	Rated for 5.5 V/ns peak diode recovery dV/dt-prevents false turn-on during fast voltage transients
Fast switching	td(on) = 10 ns, tr = 34 ns, td(off) = 23 ns, tf = 24 ns at V_DD = 50 V, R_g = 12 Ω
Simple drive requirements	V_GS(th) = 2.0–4.0 V and low C_iss = 670 pF enable direct microcontroller GPIO driving
175 °C operating temperature	Enables use in high-ambient environments (e.g., automotive engine bays, industrial motor drives)

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
STP16NF10	V_DS = 100 V, R_DS(on) = 0.18 Ω, Q_g = 22 nC, no avalanche rating specified	Lacks repetitive avalanche rating; unsuitable for unclamped inductive loads without external clamping	Prefer where gate drive power is critical and avalanche stress is absent
IXTP16N10P	V_DS = 100 V, R_DS(on) = 0.15 Ω, Q_g = 24 nC, E_AS = 72 mJ, TO-220FP package (full-pack)	TO-220FP has insulated tab and lower R_thJA; slightly better R_DS(on) but same thermal interface constraints	Prefer when electrical isolation of drain tab is required without additional insulator kit

Compared with STP16NF10 and IXTP16N10P, the IRF530L offers verified repetitive avalanche capability and identical TO-220AB mechanical footprint-enabling drop-in replacement in legacy designs where ruggedness and thermal mounting compatibility are prioritized over minimal Q_g reduction.

FAQ

What is the maximum continuous drain current for IRF530L at 100 °C case temperature?

The IRF530L supports 10 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the TO-220AB package and ensures safe operation within the 175 °C maximum junction temperature limit. Designers must verify heatsink performance to maintain T_C ≤ 100 °C under full load. The IRF530L datasheet specifies linear derating beyond 25 °C at 0.59 W/°C.

Does IRF530L have a fully rated avalanche capability, and how is it tested?

Yes, the IRF530L is repetitively avalanche rated with I_AR = 14 A and E_AR = 8.8 mJ, tested per JEDEC JESD24-11. Single-pulse avalanche energy is 69 mJ (E_AS), measured with V_DD = 25 V, L = 528 µH, R_g = 25 Ω, and I_AS = 14 A. These values are confirmed in the Vishay S21-0819-Rev. C datasheet and apply directly to the IRF530L variant.

What is the gate-source threshold voltage range for IRF530L, and how does it affect drive compatibility?

The IRF530L has a V_GS(th) range of 2.0–4.0 V at I_D = 250 µA, making it compatible with standard 5 V TTL/CMOS logic and most microcontroller GPIO outputs. This threshold allows reliable turn-on with 5 V drive while maintaining noise immunity. The IRF530L does not require dedicated gate drivers in low-frequency (<100 kHz), moderate-current applications due to its low Q_g and gate charge profile.

Is IRF530L RoHS-compliant, and what are its lead-free ordering options?

The IRF530L is offered in lead-free versions: IRF530PbF (lead-free, halogen-containing) and IRF530PbF-BE3 (lead-free and halogen-free). Both comply with EU RoHS Directive 2011/65/EU. The base IRF530L part number refers to the standard leaded version; RoHS compliance must be confirmed via the suffix. Vishay documentation confirms material categorization per doc# 99912.

How does the body diode performance of IRF530L impact its use in synchronous vs. asynchronous topologies?

The IRF530L body diode has V_SD = 2.5 V at I_S = 14 A and t_rr = 150–280 ns, making it suitable for asynchronous (freewheeling) operation but inefficient for synchronous rectification. In buck converters, using IRF530L as both high- and low-side switches increases conduction loss versus dedicated low-V_F Schottky or logic-level MOSFETs. The IRF530L is best applied in single-switch topologies or as high-side only where body diode conduction is brief and infrequent.
