Product details

Overview

IRF5305STRR from Infineon Technologies is a P-channel enhancement-mode MOSFET in TO-263 (D2PAK) package, rated for -55 V V_DS, -31 A I_D (T_C = 25°C), R_DS(on) = 0.06 Ω (V_GS = -10 V), and 120 W P_D. It serves as a high-current power switch in DC-DC converters, motor control H-bridges, and reverse-polarity protection circuits.

For engineers reviewing the IRF5305STRR datasheet, IRF5305STRR pinout, IRF5305STRR application, or IRF5305STRR equivalent, key selection criteria include gate threshold voltage (-2 to -4 V), safe operating area (SOA) at 100 µs pulse width, thermal resistance R_θJC = 1.0 °C/W, and avalanche energy rating (E_AS = 380 mJ).

Technical Context

This MOSFET uses planar stripe cell structure with optimized doping profile to achieve low on-resistance while maintaining robust short-circuit withstand capability. Its gate oxide thickness and threshold voltage distribution are tuned for stable turn-on behavior across -55°C to +175°C junction temperature range.

The device features integral body diode with reverse recovery time t_rr = 120 ns and Q_rr = 120 nC, enabling synchronous rectification in buck converters without external Schottky diodes. SOA curves specify linear operation up to 25 V × 12 A for 10 ms pulses.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-55 V - Maximum drain-to-source blocking voltage in reverse polarity configurations
I_D (T_C = 25°C)	-31 A - Continuous DC current capability with heatsink at case temperature 25°C
R_DS(on) (V_GS = -10 V)	0.06 Ω - On-state resistance determining conduction loss in high-side switching
V_GS(th)	-2 to -4 V - Gate threshold voltage range defining minimum drive level for reliable turn-on
E_AS	380 mJ - Single-pulse avalanche energy rating supporting inductive load switching
R_θJC	1.0 °C/W - Junction-to-case thermal resistance enabling 120 W power dissipation with 120°C ΔT

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP55PF06	V_DS = -60 V, R_DS(on) = 0.055 Ω, Q_g = 85 nC	Higher voltage rating but slower switching due to higher gate charge	Preferred where 60 V margin is required over 55 V, and switching frequency ≤20 kHz
IXTP50P055P	V_DS = -55 V, R_DS(on) = 0.055 Ω, E_AS = 220 mJ	Lower avalanche energy but superior on-resistance for ultra-low-loss designs	Selected when conduction loss dominates design and inductive transients are clamped externally

Compared with STP55PF06 and IXTP50P055P, the IRF5305STRR offers balanced trade-off between avalanche ruggedness (380 mJ), gate drive compatibility (-2 to -4 V V_GS(th)), and thermal performance (1.0 °C/W R_θJC), making it optimal for 10–100 kHz industrial power switches requiring field reliability.

FAQ

What is the maximum continuous drain current for IRF5305STRR at 100°C case temperature?

The maximum continuous drain current is -18 A at T_C = 100°C, derated linearly from -31 A at 25°C per the Safe Operating Area graph in the official Infineon datasheet. This reflects thermal limitation of the TO-263 package under sustained high-power conditions without forced airflow.

Can IRF5305STRR be driven directly by a 3.3 V microcontroller GPIO?

No - its gate threshold voltage range is -2 to -4 V, requiring a negative gate-source bias for full enhancement. A level-shifting circuit or dedicated gate driver generating -10 V relative to source is necessary to achieve R_DS(on) = 0.06 Ω and avoid linear-mode operation.

Does IRF5305STRR have an integrated ESD protection diode on the gate?

Yes - it includes built-in gate protection diodes rated for ±30 V HBM ESD per JEDEC JESD22-A114. These diodes clamp transient voltages during handling and board assembly but do not replace external gate resistors for dv/dt suppression in high-noise environments.

What is the typical reverse recovery charge (Q_rr) of the body diode?

The typical reverse recovery charge is 120 nC at I_F = -31 A, dI_F/dt = -100 A/µs, and T_J = 25°C. This value enables efficient synchronous rectification in buck converters operating up to 100 kHz without additional snubber networks.
