Infineon Technologies IRL530NSPBF

Overview

IRL530NSPBF from Infineon Technologies is a 100V, 17A, 0.085Ω N-channel logic-level power MOSFET in TO-220AB package, optimized for DC-DC converters and motor control with V_GS(th) = 1.0–2.0V and R_DS(on) = 85mΩ @ V_GS = 5V. It features low gate charge (Q_g = 24nC), fast switching, and enhanced body diode ruggedness for hard-switched topologies.

For engineers reviewing the IRL530NSPBF datasheet, IRL530NSPBF pinout, IRL530NSPBF application, or IRL530NSPBF equivalent, key selection criteria include logic-level gate drive compatibility, continuous drain current rating at 100°C case temperature, body diode reverse recovery performance (t_rr = 120ns), and thermal resistance (R_θJC = 1.2°C/W).

Technical Context

This MOSFET employs planar stripe silicon technology with optimized channel geometry to achieve low R_DS(on) while maintaining robust avalanche capability (E_AS = 190mJ). Its gate oxide is rated for ±20V maximum V_GS, supporting standard 5V microcontroller drive without level-shifting.

The device integrates a fast, soft-recovery body diode with Q_rr = 120nC and peak I_RRM = 17A, enabling reliable operation in synchronous buck converters and H-bridge motor drivers where freewheeling current reversal occurs frequently.

Key Specifications

Pinout & Package

TO-220AB package with isolated tab (drain-connected), 3-pin through-hole mounting, 15.8mm × 10.16mm footprint, lead-free (PbF) finish per JEDEC J-STD-609.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.

Compared with STP16NF10 and FQP30N06L, the IRL530NSPBF uniquely balances 100V rating, true logic-level gate drive (V_GS(th) ≤2.0V), and proven avalanche ruggedness-making it optimal for 24–48V industrial motor and power supply designs where reliability under overcurrent stress is critical.

FAQ

Is IRL530NSPBF pin-compatible with the legacy IRF530?

No. While both use TO-220AB packages, the IRL530NSPBF has a logic-level gate threshold (1.0–2.0V) versus IRF530's 2.0–4.0V, and its R_DS(on) is 85mΩ @ 5V vs. 0.16Ω for IRF530. Pinout is identical (D-G-S), but gate drive requirements differ significantly.

What is the maximum safe operating temperature for continuous 17A drain current?

The 17A rating is specified at T_C = 100°C. With R_θJC = 1.2°C/W and P_D = I²R = 24.6W, junction temperature reaches 130°C at 100°C case. Derating is required above 100°C case; maximum continuous I_D drops to ~12A at T_C = 125°C.

Can IRL530NSPBF be used in avalanche mode for inductive load switching?

Yes. It is fully rated for repetitive avalanche with E_AS = 190mJ at T_J = 25°C. For reliable operation, ensure peak V_DS stays within 100V and single-pulse energy does not exceed E_AS; derate E_AS linearly to 95mJ at T_J = 125°C.

Does the "SPBF" suffix indicate RoHS compliance?

Yes. "SPBF" denotes lead-free (PbF) construction per RoHS Directive 2011/65/EU and IPC/JEDEC J-STD-609A Class 3. The "P" in the suffix explicitly identifies lead-free plating, and the device carries the RoHS-compliant marking on the package.
