Product details

Overview

IPB80P04P4L04ATMA2 from Infineon Technologies is a P-channel logic-level enhancement-mode MOSFET in PG-TO263-3-2 package, rated for -40 V V_DS, 4.4 mΩ R_DS(on) at V_GS = -10 V and I_D = -80 A, with 175 °C maximum junction temperature and AEC-Q101 qualification. It delivers high-current switching in automotive body control modules, battery disconnect circuits, and reverse polarity protection.

For engineers reviewing the IPB80P04P4L04ATMA2 datasheet, IPB80P04P4L04ATMA2 pinout, IPB80P04P4L04ATMA2 application, or IPB80P04P4L04ATMA2 equivalent, key selection criteria include its -80 A continuous drain current at T_C = 100 °C, 1.2 K/W thermal resistance (junction-to-case), 100% avalanche-tested ruggedness, and logic-level gate drive compatibility down to -4.5 V.

Technical Context

This device implements a trench-based OptiMOS®-P2 silicon structure optimized for low R_DS(on) and fast switching in high-side load switch configurations. Its gate threshold voltage range of -1.2 V to -2.2 V enables direct interfacing with 3.3 V and 5 V microcontroller outputs without level-shifting.

The integrated body diode exhibits 65 ns reverse recovery time and 90 nC Q_rr at I_F = -50 A and di_F/dt = -100 A/µs, supporting efficient synchronous rectification and freewheeling in DC-DC converters and motor drives.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF4905PbF	R_DS(on) = 20 mΩ @ -10 V; lower current rating (-74 A); no AEC-Q101 qualification	Suitable for industrial power supplies but not automotive-grade designs requiring qualification	Select when cost sensitivity outweighs automotive qualification and thermal performance needs
STP80PF55	R_DS(on) = 5.5 mΩ @ -10 V; higher gate charge (220 nC); TO-220 package only	Limited to lower-frequency switching due to slower t_r/t_f; lacks MSL1 reflow rating	Prefer for legacy through-hole assembly where thermal mass compensates for higher R_DS(on)

Compared with IRF4905PbF and STP80PF55, IPB80P04P4L04ATMA2 offers superior thermal performance (1.2 K/W vs ≥2.5 K/W), AEC-Q101 compliance, and tighter R_DS(on) distribution-making it optimal for space-constrained, high-reliability automotive power stages.

FAQ

What is the maximum allowable gate-source voltage for IPB80P04P4L04ATMA2?

The absolute maximum V_GS is -16 V. Operation beyond this risks permanent gate oxide damage. Recommended gate drive stays within -4.5 V to -10 V for logic-level compatibility and optimal R_DS(on) performance. Transient overshoot must be clamped below -16 V using Zener diodes or active gate control.

Does IPB80P04P4L04ATMA2 require a gate resistor for stability?

Yes-a series gate resistor (typically 10 Ω to 47 Ω) is required to dampen ringing caused by gate loop inductance and Miller capacitance interaction. This prevents false turn-on during high dv/dt events and controls switching speed to balance EMI and power loss. Values are validated in Infineon's AN2015-04 application note.

Can IPB80P04P4L04ATMA2 be used in parallel configurations?

Yes, but only with matched devices and symmetrical PCB layout. Thermal coupling and gate drive skew must be minimized; gate resistors should be individually placed. Parallel operation increases current capacity but requires careful attention to current sharing-R_DS(on)'s positive tempco helps self-balancing above 100 °C junction temperature.

Is the drain tab electrically isolated from the PCB mounting pad?

No-the drain tab is electrically connected to Pin 2 (Drain) and must be soldered to a dedicated, non-grounded copper pour. Electrical isolation requires insulating thermal interface material or a plastic insulator kit. Direct mounting to chassis ground creates a short circuit unless the system design intentionally references drain to chassis.
