Product details

Overview

IRFD9020 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in HVMDIP package, rated for -60 V drain-source voltage, 0.28 Ω R_DS(on) at V_GS = -10 V, and 1.6 A continuous drain current at 25 °C. It features repetitive avalanche rating, fast switching (13 ns turn-on delay), and 175 °C maximum junction temperature - used in DC-DC converter high-side switches and industrial relay drivers.

For engineers reviewing the IRFD9020 datasheet, IRFD9020 pinout, IRFD9020 application, or IRFD9020 equivalent, key selection criteria include its -60 V V_DS, thermal performance in through-hole DIP layout, body diode recovery time (100–200 ns), and compatibility with -10 V gate drive in low-power high-side configurations.

Technical Context

This P-channel MOSFET operates as a high-side switch in non-synchronous buck converters and solid-state relay replacements, leveraging its integrated body diode and -4.5 V/ns peak diode recovery dV/dt rating. Its 19 nC total gate charge and 5.4 nC gate-source charge support moderate-speed switching without excessive driver loss.

The device uses third-generation silicon process for ruggedized avalanche capability (140 mJ single-pulse E_AS) and stable R_DS(on) over temperature (±0.056 V/°C V_DS tempco). Thermal resistance R_thJA is 120 °C/W, enabling 1.3 W dissipation at 25 °C ambient with standard PCB copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - supports input rails up to 48 V DC in high-side switch applications
R_DS(on) @ V_GS = -10 V	0.28 Ω - limits conduction loss to ≤ 720 mW at 1.6 A ID
Q_g	19 nC - determines gate driver current requirement (~1.9 mA avg for 100 kHz f_sw)
I_D (continuous, T_A = 25 °C)	-1.6 A - defines max steady-state load current without heatsink
t_r / t_f	68 ns / 29 ns - enables <100 kHz PWM operation with minimal switching loss
V_SD @ I_S = -1.6 A	-6.3 V - impacts body diode conduction loss during freewheeling phase
E_AS	140 mJ - allows safe unclamped inductive turn-off in relay/snubberless designs

Pinout & Package

HVMDIP (High Voltage Mini-DIP) package: 4-pin through-hole, dual-drain configuration (pins 1 & 4), gate on pin 2, source on pin 3. Dual drain improves thermal path to PCB copper; case length 8.38 mm max, pin pitch 2.54 mm.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 & Pin 4 (Drain)	Main current path collector	Dual-drain structure lowers thermal resistance and increases current handling margin
Pin 2 (Gate)	Control electrode	Requires negative V_GS (≤ -2.0 V threshold); 100 nA leakage ensures low standby power
Pin 3 (Source)	Reference node for gate drive	Connected to load return; body diode anode tied internally to source

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under inductive load switching without external snubbers
Dynamic dV/dt rating (-4.5 V/ns)	Prevents false turn-on during high dv/dt transients in motor or relay drive circuits
175 °C operating temperature	Supports sealed industrial enclosures with limited airflow and high ambient temperatures
End stackable HVMDIP package	Allows vertical stacking of multiple units on 0.1" grid for compact multi-channel layouts
Fast switching (t_d(on) = 13 ns)	Reduces transition losses in 50–100 kHz DC-DC topologies with minimal gate drive complexity

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel high-side switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFD120	V_DS = -100 V, R_DS(on) = 0.27 Ω, Q_g = 22 nC, same HVMDIP package	Better voltage margin for 72 V systems; higher gate charge increases driver demand	Choose when input voltage exceeds 48 V but thermal budget allows 22 nC Q_g
STP12PF06	V_DS = -60 V, R_DS(on) = 0.30 Ω, Q_g = 16 nC, TO-220 package	Lower gate charge reduces driver loss; TO-220 requires heatsink for >1 W dissipation	Choose when board space permits TO-220 and lower switching loss outweighs through-hole assembly cost

Compared with IRFD9020, IRFD120 offers higher voltage headroom at slightly increased gate drive burden, while STP12PF06 trades HVMDIP's automated insertion advantage for lower Q_g and higher thermal capacity in TO-220 - both require layout review due to differing footprints and thermal paths.

FAQ

What is the maximum continuous drain current for IRFD9020 at 100 °C ambient temperature?

The IRFD9020 supports -1.1 A continuous drain current at T_A = 100 °C, derated from -1.6 A at 25 °C using the linear derating factor of 0.0083 W/°C. This reflects thermal limitations of the HVMDIP package without forced airflow or heatsinking. The IRFD9020 must be mounted on adequate copper area to sustain this current reliably.

Does IRFD9020 have avalanche capability, and how is it specified?

Yes, the IRFD9020 is repetitively avalanche rated with 0.13 mJ EAR and 140 mJ single-pulse E_AS. The datasheet specifies E_AS under conditions of V_DD = -25 V, L = 15 mH, R_g = 25 Ω, and I_AS = -3.2 A. This makes IRFD9020 suitable for inductive load switching without external snubbers in properly designed circuits.

What is the gate threshold voltage range for IRFD9020, and how does it affect drive requirements?

The IRFD9020 has a gate-source threshold voltage V_GS(th) ranging from -2.0 V to -4.0 V at I_D = -1 μA. This means full enhancement begins near -4 V, and logic-level drive (e.g., -5 V) ensures robust turn-on. Driving below -2 V risks partial conduction and excessive R_DS(on); the IRFD9020 thus requires negative gate bias relative to source, not TTL-compatible levels.

Can IRFD9020 be used in parallel configurations, and what precautions apply?

The IRFD9020 is not characterized for paralleling in the datasheet. Its negative temperature coefficient of R_DS(on) helps balance current, but mismatched threshold voltages and layout asymmetry may cause uneven sharing. For higher current, Vishay recommends using a single higher-rated device rather than paralleling IRFD9020 units unless validated per application.

What is the body diode reverse recovery time (t_rr) of IRFD9020, and why does it matter in switching applications?

The IRFD9020 body diode exhibits t_rr of 100–200 ns at T_J = 25 °C, I_F = -11 A, and di/dt = 100 A/μs. In buck or half-bridge topologies, this recovery time affects voltage overshoot and switching loss during freewheeling transitions. Designers must account for t_rr in dead-time selection and snubber design - critical for stable operation of IRFD9020 in hard-switched circuits.
