Product details

Overview

IPB100N12S305ATMA2 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO263-3-2 package, rated for 120 V V_DS, 4.8 mΩ max R_DS(on) at 100 A and 10 V V_GS, with 175 °C maximum junction temperature. It delivers high-current switching in automotive DC-DC converters, motor control inverters, and battery disconnect circuits.

For engineers reviewing the IPB100N12S305ATMA2 datasheet, IPB100N12S305ATMA2 pinout, IPB100N12S305ATMA2 application, or IPB100N12S305ATMA2 equivalent, key selection criteria include avalanche energy (1445 mJ), thermal resistance (0.5 K/W j-c), gate charge (139–185 nC), and automotive-grade reliability under 100% single-pulse avalanche test.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its 4.0–4.8 mΩ typical R_DS(on) at 100 A enables efficient high-current operation, while its 8900–11570 pF input capacitance and 220–330 pF reverse transfer capacitance support fast, controlled turn-on/turn-off with minimal Miller effect.

The integrated body diode exhibits 0.6–1.2 V forward voltage at 100 A and 25 °C, with 108 ns reverse recovery time and 380 nC Q_rr, enabling synchronous rectification and freewheeling in hard-switched topologies without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	120 V - supports full 12 V automotive battery rail with margin against load dump transients
R_DS(on) max	4.8 mΩ at V_GS = 10 V, I_D = 100 A - enables <1 W conduction loss at 100 A, critical for thermal management
I_D continuous	100 A at T_C = 25 °C - defined by bondwire limit; usable up to 100 A with proper heatsinking
E_AS	1445 mJ at I_D = 50 A - ensures robustness against inductive switching surges in motor drives
Q_g	139–185 nC - determines gate driver power requirement and switching speed trade-off
R_thJC	0.5 K/W - allows direct thermal path to heatsink; enables >150 W dissipation with ΔT_jc ≤ 75 K
T_j max	+175 °C - certified for under-hood environments including engine control units and traction inverters

Pinout & Package

IPB100N12S305ATMA2 is housed in PG-TO263-3-2 (D²PAK) surface-mount package with isolated drain tab, designed for high-power PCB mounting and thermal interface to copper pour or heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for channel current	Internally connected to all source dies; must be low-inductance connection to ground plane
Pin 2 (Gate)	Control terminal for channel modulation	High-impedance input requiring low-noise gate drive; sensitive to ESD and ringing
Pin 3 (Drain)	Main power output terminal	Exposed metal tab electrically tied to drain; primary thermal conduction path to PCB copper

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use across temperature, humidity, and vibration stress profiles per JESD47
100% single-pulse avalanche tested	Guarantees ruggedness against unclamped inductive switching events without derating
MSL1 rating (260 °C peak reflow)	Enables standard lead-free SMT assembly without moisture sensitivity concerns
Integrated body diode with low Q_rr	380 nC reverse recovery charge reduces switching loss and EMI in freewheeling paths
Optimized gate charge profile	Q_gd/Q_gs ratio of ~0.75 improves controllability and reduces risk of spurious turn-on

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP100N12S3-05	PG-TO220-3-1 through-hole package; identical electrical specs but higher R_thJA (62 K/W vs 40 K/W on PCB)	Suitable for prototyping or lower-power designs where manual soldering and larger heatsinks are acceptable	Select when board-level thermal constraints allow less aggressive cooling or when legacy TO-220 footprint compatibility is required
IPI100N12S3-05	PG-TO262-3-1 (I2PAK) package; same die, slightly higher R_thJC (0.55 K/W), no isolated drain tab	Preferred for medium-volume industrial motor drives where automated assembly and moderate thermal performance suffice	Choose when cost-sensitive production favors I2PAK's lower assembly cost and sufficient thermal margin exists

Compared with IPP100N12S3-05 and IPI100N12S3-05, IPB100N12S305ATMA2 offers superior thermal performance via its isolated D²PAK drain tab and lowest R_thJC, making it optimal for space-constrained, high-reliability automotive power stages where PCB copper area is limited.

FAQ

What is the maximum allowable gate-source voltage for IPB100N12S305ATMA2?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent oxide damage, while gate drive below 4.5 V may not fully enhance the channel. Recommended gate drive is 10 V for nominal R_DS(on), with 12–15 V used in high-speed switching to reduce Q_gd-dominated delay.

Does IPB100N12S305ATMA2 require a gate resistor, and what value is recommended?

Yes-a gate resistor is mandatory to dampen ringing and control dV/dt. For 100 A switching at 100 kHz, a 3.3–5.6 Ω resistor is typical. Lower values increase switching speed but raise EMI and gate driver stress; higher values reduce losses but extend transition times and increase switching loss.

Can IPB100N12S305ATMA2 replace IPP100N12S3-05 in an existing TO-220 layout?

No-it uses PG-TO263-3-2 (D²PAK), which has different pad geometry, thermal pad requirements, and mounting orientation. Direct replacement requires PCB redesign to accommodate the surface-mount drain tab and 3-pin footprint. Thermal and electrical performance will improve, but mechanical fit is not interchangeable.

Is the body diode suitable for continuous freewheeling in a synchronous buck converter?

Yes-the body diode is rated for 100 A continuous forward current at T_C = 25 °C and exhibits low V_SD (0.6–1.2 V) and fast t_rr (108 ns). However, for best efficiency above 20 A, synchronous rectification using a second MOSFET is preferred to avoid diode conduction loss.
