Product details

Overview

IRFR9020TRLPBF 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 synchronous rectification in telecom power supplies.

For engineers reviewing the IRFR9020TRLPBF datasheet, IRFR9020TRLPBF pinout, IRFR9020TRLPBF application, or IRFR9020TRLPBF 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), repetitive avalanche rating (-9.9 A I_AR), and compatibility with standard PCB layout practices for DPAK packages.

Technical Context

This P-channel MOSFET employs planar silicon technology optimized for low R_DS(on) and high transconductance (g_fs = 2.3–3.5 S), enabling efficient operation in high-frequency switching topologies. Its body diode exhibits t_rr = 56–280 ns and Q_rr = 0.17–0.85 nC, supporting moderate-speed synchronous rectification without external snubbing.

The device features dynamic dV/dt immunity (5.8 V/ns), gate threshold voltage of -2.0 to -4.0 V, and operates across -55 to +150 °C junction temperature range. Its DPAK package provides low-inductance source/drain paths (L_S = 7.5 nH, L_D = 4.5 nH), critical for minimizing switching losses and voltage overshoot in hard-switched converters.

FAQ

What is the maximum continuous drain current rating for IRFR9020TRLPBF at 100 °C case temperature?

The IRFR9020TRLPBF supports -6.3 A continuous drain current at T_C = 100 °C, derived from its linear derating factor of 0.33 W/°C and 42 W maximum power dissipation at 25 °C. This rating reflects real-world thermal limits when mounted on a 1" square FR-4 PCB with adequate copper area, ensuring safe operation in enclosed industrial enclosures without forced airflow.

Does IRFR9020TRLPBF have a specified peak diode recovery dV/dt rating?

Yes, the IRFR9020TRLPBF has a specified peak diode recovery dV/dt rating of 5.8 V/ns under test conditions of I_SD ≤ -9.9 A, dI/dt ≤ -120 A/μs, V_DD ≤ 40 V, and T_J ≤ 150 °C. This parameter quantifies the device's immunity to false turn-on during body diode commutation, critical for reliable operation in synchronous rectifier and H-bridge configurations.

What is the gate-source threshold voltage range for IRFR9020TRLPBF?

The gate-source threshold voltage (V_GS(th)) for IRFR9020TRLPBF is specified from -2.0 V to -4.0 V at V_DS = V_GS and I_D = -50 μA. This range ensures consistent turn-on behavior across process variation and temperature, allowing reliable operation with 3.3 V or 5 V logic-level gate drivers without requiring negative bias generation.

Can IRFR9020TRLPBF be used in avalanche mode repeatedly?

Yes, the IRFR9020TRLPBF is rated for repetitive avalanche operation with I_AR = -9.9 A and E_AR = 4.2 mJ per pulse, provided pulse width is limited by maximum junction temperature (see Figure 16 in datasheet). This capability enables robust design in inductive load switching applications such as solenoid drivers and relay controls without external snubber networks.

What is the thermal resistance from junction to case (R_thJC) for IRFR9020TRLPBF?

The maximum junction-to-case (drain) thermal resistance R_thJC for IRFR9020TRLPBF is 3.0 °C/W. This value is measured from the silicon die to the exposed drain pad, enabling accurate thermal modeling when the device is soldered directly to a PCB copper pour or attached to an external heatsink-critical for predicting junction temperature rise in high-power density layouts.
