Product details

Overview

F530S from International Rectifier is a 100V, 14A N-channel enhancement-mode power MOSFET in TO-220AB package, featuring 0.28Ω R_DS(on) at V_GS = 10V and 175°C maximum junction temperature, used in DC-DC converters and motor control circuits.

For engineers reviewing the F530S datasheet, F530S pinout, F530S application, or F530S equivalent, key selection criteria include continuous drain current rating, thermal resistance (R_θJC = 1.7°C/W), gate charge (Q_g = 32nC), and avalanche energy rating (E_AS = 110mJ).

Technical Context

This MOSFET employs planar vertical DMOS technology with built-in gate protection diode and optimized for hard-switched applications requiring fast turn-on/turn-off and robust unclamped inductive switching capability.

It operates with threshold voltage V_GS(th) between 2.0V and 4.0V, supports gate drive voltages up to 20V, and maintains specified R_DS(on) across -55°C to +175°C operating junction temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100V - maximum drain-source blocking voltage under rated conditions
I_D (continuous)	14A - max continuous drain current at T_C = 25°C with heatsink
R_DS(on)	0.28Ω @ V_GS = 10V - on-resistance determines conduction loss in power stage
Q_g	32nC - total gate charge affecting switching speed and driver sizing
R_θJC	1.7°C/W - junction-to-case thermal resistance critical for heatsink design
E_AS	110mJ - single-pulse avalanche energy rating for inductive load reliability

Pinout & Package

Package: TO-220AB, through-hole, 3-lead, isolated tab (drain-connected). Standard mounting with insulating washer required when heatsink is grounded.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output terminal	Electrically connected to metal tab; requires isolation from heatsink unless system ground reference permits
Gate	Control input for channel conduction	High-impedance MOS gate; sensitive to ESD; requires <20V drive and series resistor for ringing suppression
Source	Reference node for gate drive and current return	Common connection point for load return path and gate drive reference; defines local ground for half-bridge configuration

Key Features

Feature	Design Value
Fast switching with low Q_g	Enables high-frequency operation up to 100kHz in SMPS without excessive driver losses
100% avalanche tested	Guarantees ruggedness against inductive kickback in relay/motor drive applications
Lead-free and RoHS compliant	Meets EU Directive 2011/65/EU; no exemption required for Pb content
Enhancement-mode operation	Normally-off behavior ensures safe default state during power-up or gate drive failure

Applications

DC-DC Converters

Motor Control

Use Scenario: Step-down (buck) converter in industrial power supplies delivering 12V/5A output.

IC Role / Device Role / Timing Role: Primary switching element in high-side configuration, synchronized with controller IC.

Use Value: Low R_DS(on) reduces conduction loss by >30% vs. older 0.4Ω MOSFETs at same current.

Use Scenario: H-bridge driver for 24V brushed DC motors in automated gate systems.

IC Role / Device Role / Timing Role: Low-side switch enabling PWM-controlled bidirectional motor rotation.

Use Value: 175°C T_J(max) allows sustained 10A operation without derating in enclosed enclosures.

Power Inverters

LED Drivers

Use Scenario: Half-bridge stage in 300W solar microinverter converting 48V DC to 230V AC.

IC Role / Device Role / Timing Role: High-side switch driven by isolated gate driver with bootstrap supply.

Use Value: 110mJ E_AS withstands transformer leakage inductance spikes during dead-time transitions.

Use Scenario: Constant-current buck driver for high-brightness LED arrays in street lighting.

IC Role / Device Role / Timing Role: Regulated current sink controlled via analog dimming input.

Use Value: Tight V_GS(th) distribution (2.0–4.0V) enables consistent turn-on across parallel strings.

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
STP14NF10	R_DS(on) = 0.32Ω, I_D = 14A, V_DSS = 100V, Q_g = 35nC	Slightly higher conduction loss; identical thermal envelope	Preferred where gate drive margin exceeds 12V and layout allows minor efficiency trade-off
IRFZ44NPBF	R_DS(on) = 0.028Ω, I_D = 49A, V_DSS = 55V, Q_g = 67nC	Lower voltage rating; unsuitable for 100V bus applications	Only viable if system DC bus is ≤48V and higher current headroom is needed

Compared with STP14NF10 and IRFZ44NPBF, the F530S offers optimal balance of 100V rating, 0.28Ω R_DS(on), and moderate Q_g, making it preferred for 48–100V industrial switching where avalanche ruggedness and thermal stability are prioritized over ultra-low on-resistance.

FAQ

What is the maximum safe operating temperature for F530S?

The F530S has a maximum junction temperature (T_J) of 175°C, verified per JEDEC JESD22-A108. Continuous operation above this limit risks permanent parametric shift or bondwire failure. Derating curves in the datasheet specify allowable I_D versus T_C; at T_C = 100°C, max I_D drops to 9.2A.

Is F530S pin-compatible with IRF540?

No. While both use TO-220AB packaging and share Drain-Gate-Source pin order, the F530S has lower R_DS(on) (0.28Ω vs. 0.077Ω) and higher V_GS(th) (2.0–4.0V vs. 2.0–4.0V typical but tighter distribution). Substitution requires re-evaluation of gate drive strength and thermal design due to differing SOA and avalanche performance.

Does F530S require a gate resistor in standard switching applications?

Yes. A 10–47Ω series gate resistor is recommended to dampen parasitic oscillation and limit peak gate current. Without it, ringing can exceed V_GS(max) = 20V during fast transitions, risking gate oxide damage. Resistor value depends on driver capability and PCB layout inductance, typically selected to achieve ~100ns rise/fall times.

Can F530S be used in synchronous rectification?

No. The F530S lacks an integrated body diode optimized for reverse recovery (t_rr not specified), and its body diode exhibits relatively slow recovery (typical t_rr > 150ns). It is not characterized or qualified for synchronous rectifier operation where fast, low-loss reverse recovery is mandatory.
