Infineon Technologies IPB80P03P405ATMA1

Overview

IPB80P03P405ATMA1 from Infineon Technologies is a P-channel enhancement-mode MOSFET rated for -30 V V_DS, 4.1–5 mΩ R_DS(on) at -10 V V_GS and -80 A I_D, qualified to AEC-Q101, with 175 °C maximum junction temperature and MSL1 reflow compatibility. It serves as a high-current load switch in automotive body control modules, battery disconnect circuits, and reverse-polarity protection.

For engineers reviewing the IPB80P03P405ATMA1 datasheet, IPB80P03P405ATMA1 pinout, IPB80P03P405ATMA1 application, or IPB80P03P405ATMA1 equivalent, key selection criteria include its -80 A continuous drain rating at T_C = 100 °C, 1.1 K/W R_thJC, 410 mJ single-pulse avalanche energy, and -1.3 V diode forward voltage at -80 A.

Technical Context

This device operates as a normally-off P-channel power switch with gate threshold voltage between -2.0 V and -4.0 V, enabling robust low-side switching control using standard logic-level drivers. Its optimized charge characteristics-Q_g = 100–130 nC, Q_gd = 10–20 nC-support fast, low-loss switching in DC-DC converters and motor drive H-bridge high-side configurations.

Thermal design is enabled by its PG-TO263-3-2 package with direct-drain thermal pad and 1.1 K/W junction-to-case resistance. The integrated body diode exhibits t_rr = 100 ns and Q_rr = 80 nC under -100 A/µs di/dt, supporting synchronous rectification and freewheeling in high-frequency power stages.

FAQ

What is the maximum safe operating temperature for IPB80P03P405ATMA1?

The device supports continuous operation up to +175 °C junction temperature, validated per AEC-Q101 stress testing. At T_C = 100 °C, it delivers full -80 A continuous drain current with V_GS ≤ -6 V. Derating begins above this case temperature, and thermal design must maintain T_j ≤ 175 °C under worst-case ambient and power dissipation conditions.

Does IPB80P03P405ATMA1 require a negative gate driver?

No - it is a P-channel device that turns on with a gate voltage *lower* than the source, but standard 0 V / -12 V logic or microcontroller outputs can drive it directly. With V_GS(th) between -2.0 V and -4.0 V, a -10 V gate-source bias fully enhances the channel, while 0 V gate relative to source ensures full turn-off in high-side configurations.

Can IPB80P03P405ATMA1 be used in synchronous rectification?

Yes - its low R_DS(on) (4.1–5 mΩ), fast switching (t_f = 20 ns), and well-characterized body diode (t_rr = 100 ns, Q_rr = 80 nC) make it suitable for synchronous rectification in isolated DC-DC converters. However, external gate timing control is required to avoid shoot-through, as the device lacks integrated adaptive dead-time control.

Is the PG-TO263-3-2 package lead-free and RoHS compliant?

Yes - IPB80P03P405ATMA1 is RoHS compliant and uses lead-free terminations. Its MSL1 rating confirms compatibility with standard lead-free reflow profiles peaking at 260 °C, and the package meets JEDEC J-STD-020 moisture sensitivity requirements without dry-packaging or baking prior to assembly.
