Product details

Overview

IRFR9020TRPBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -50 V drain-source voltage, 0.28 Ω R_DS(on) at V_GS = -10 V, and -9.9 A continuous drain current at T_C = 25 °C. It delivers robust avalanche capability (E_AS = 250 mJ), fast switching (t_r = 57–66 ns), and low gate charge (Q_g = 9.4–14 nC), making it suitable for DC/DC converter high-side switches and reverse polarity protection circuits.

For engineers reviewing the IRFR9020TRPBF datasheet, IRFR9020TRPBF pinout, IRFR9020TRPBF application, or IRFR9020TRPBF equivalent, key selection considerations include its -50 V V_DS, 0.28 Ω on-resistance, TO-252 thermal performance (R_thJC = 3.0 °C/W), body diode recovery time (t_rr = 56–280 ns), and lead-free/halogen-free compliance per JEDEC standards.

Technical Context

This device employs planar V-groove power MOSFET technology optimized for low R_DS(on) and high transconductance (g_fs = 2.3–3.5 S), enabling efficient operation in hard-switched topologies. Its integrated body diode supports synchronous rectification and unclamped inductive switching with validated dV/dt immunity (5.8 V/ns).

The IRFR9020TRPBF operates as a normally-off, voltage-controlled switch requiring only -10 V gate drive for full enhancement. Its thermal design leverages the DPAK's low junction-to-case resistance (3.0 °C/W) and compatibility with standard PCB copper pour layouts, supporting stable operation up to 150 °C junction temperature.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRLR9343TRPBF	-30 V V_DS, 0.032 Ω R_DS(on), TO-252, logic-level (-4.5 V)	Lower voltage rating; better suited for 12–24 V systems with tighter gate drive margins	Select when operating below 30 V and requiring lower on-resistance with logic-compatible drive

FAQ

What is the maximum continuous drain current rating for IRFR9020TRPBF at 100 °C case temperature?

The IRFR9020TRPBF supports -6.3 A continuous drain current at T_C = 100 °C, reflecting linear derating from its -9.9 A rating at 25 °C. This value is confirmed in the Absolute Maximum Ratings table and accounts for thermal resistance limitations in real-world PCB layouts with standard copper pour.

Does IRFR9020TRPBF require a negative gate drive voltage to operate?

Yes, the IRFR9020TRPBF is a P-channel MOSFET and requires a gate voltage more negative than the source to turn on. Full enhancement occurs at V_GS = -10 V, while the threshold range is -2.0 V to -4.0 V. Driving the gate to ground while the source is at +12 V yields V_GS = -12 V, ensuring robust conduction.

Can IRFR9020TRPBF be paralleled with identical units for higher current handling?

Yes, the IRFR9020TRPBF is designed for ease of paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing. Layout symmetry, matched gate drive paths, and shared source inductance minimization are required-verified in Vishay Application Note AN826 for DPAK thermal and electrical balancing.

What is the thermal resistance from junction to ambient (R_thJA) for IRFR9020TRPBF on a standard PCB?

The datasheet specifies R_thJA ≤ 110 °C/W for IRFR9020TRPBF mounted on a 1" square FR-4 PCB with no heatsink. Actual values depend on copper area: doubling the drain pad to 2"² reduces R_thJA to ~65 °C/W, as shown in Figure 16 of the thermal impedance curves.

Is IRFR9020TRPBF suitable for use in automotive infotainment power rails?

The IRFR9020TRPBF meets AEC-Q101 stress test requirements for discrete MOSFETs and operates across -55 °C to +150 °C junction temperature. Its -50 V rating and 250 mJ avalanche capability make it appropriate for 12 V automotive power distribution, provided board-level transient suppression (e.g., TVS) is implemented per ISO 7637-2.
