Product details

Overview

IPP100N10S305AKSA1 from Infineon Technologies is an N-channel enhancement-mode automotive-qualified MOSFET in PG-TO220-3-1 package, rated for 100 V V_DS, 4.8 mΩ R_DS(on) max at V_GS = 10 V and I_D = 100 A, with 175 °C maximum junction temperature and 100% single-pulse avalanche tested. It serves as a high-current main switch in 12 V/48 V automotive power distribution modules.

For engineers reviewing the IPP100N10S305AKSA1 datasheet, IPP100N10S305AKSA1 pinout, IPP100N10S305AKSA1 application, or IPP100N10S305AKSA1 equivalent, key selection criteria include its 0.5 K/W R_thJC, 1445 mJ E_AS at I_D = 50 A, AEC-Q101 qualification, and gate plateau voltage of 5.5 V - all critical for robust high-side load switching in engine control units and battery disconnect systems.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology to achieve low R_DS(on) × Q_g figure-of-merit (4.8 mΩ × 176 nC), enabling efficient hard-switching in DC-DC converters and motor drivers. Its gate threshold voltage (2.0–4.0 V) ensures stable turn-on under wide supply ranges, while the 220–330 pF Crss supports predictable Miller-effect behavior during commutation.

The integrated body diode exhibits 0.6–1.2 V forward voltage at 80 A and 25 °C, with 108 ns reverse recovery time and 380 nC Q_rr, making it suitable for synchronous rectification and freewheeling in bidirectional power stages without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports 12 V/48 V automotive bus with 2× safety margin against load dump transients
R_DS(on) max	4.8 mΩ @ V_GS = 10 V, I_D = 100 A - enables ≤4.8 W conduction loss at full rated current
I_D continuous	100 A @ T_C = 25 °C - limited by bondwire; requires heatsink interface with ≤0.5 K/W thermal resistance
E_AS	1445 mJ @ I_D = 50 A - sustains single-pulse inductive energy without failure in solenoid or relay drive
Q_g total	176 nC max - determines gate driver peak current requirement (~500 mA for 350 ns rise time)
R_thJC	0.5 K/W - defines minimum heatsink thermal resistance needed to maintain T_j ≤ 175 °C at P_tot = 300 W
t_r/t_f	17 ns / 20 ns - enables ≥5 MHz switching in resonant topologies with controlled dV/dt

Pinout & Package

Package: PG-TO220-3-1 - through-hole, isolated tab, standard TO-220 footprint with drain-connected metal tab for direct heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for channel current	Low-inductance connection point for PCB ground plane; ties to source of gate driver bootstrap circuit
Pin 2 (Gate)	Control electrode for channel modulation	High-impedance input requiring <100 nA leakage; sensitive to ESD; routed away from noisy power traces
Pin 3 (Drain)	Main current output terminal	Internally connected to metal tab; must be thermally and electrically bonded to heatsink with dielectric isolation

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, UHAST
100% single-pulse avalanche tested	Guarantees ruggedness under unclamped inductive switching events up to 1445 mJ without parameter shift
MSL1 rating (260 °C peak reflow)	Enables compatibility with standard lead-free SMT assembly processes despite being a through-hole part
Optimized Crss/Ciss ratio	Crss = 220–330 pF vs Ciss = 8900–11570 pF - reduces Miller-induced shoot-through risk in half-bridge configurations
175 °C operating temperature	Supports placement near hot zones (e.g., near exhaust manifolds or inverters) without derating

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB100N10S3-05	PG-TO263-3-2 package; 4.0–4.8 mΩ R_DS(on); same die, lower R_thJA on PCB	Better suited for SMD-based power modules where board space and thermal via density allow	Select when automated assembly and compact layout are prioritized over serviceability
STL220N10F7	100 V, 2.2 mΩ typ R_DS(on), 200 A I_D, but only AEC-Q100 qualified (not Q101); higher Q_g (220 nC)	Lacks full automotive reliability validation for safety-critical powertrain use	Acceptable for non-safety-critical commercial vehicle body electronics only

FAQ

What is the maximum allowable gate-source voltage for IPP100N10S305AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent gate oxide damage. Recommended drive is 10 V for full enhancement, with 5.5 V gate plateau ensuring reliable turn-on even with driver voltage droop under load. Gate resistors should be selected to limit peak current to <1 A during switching transitions.

Does IPP100N10S305AKSA1 require a heatsink in all applications?

Yes - at 100 A continuous current, junction-to-case thermal resistance is 0.5 K/W, meaning even with ideal case-to-heatsink interface (≤0.1 K/W), ambient-to-junction rise exceeds 100 K at 300 W dissipation. A finned aluminum heatsink with ≥150 cm² surface area and forced airflow is required to maintain T_j ≤ 175 °C in sustained operation.

Can IPP100N10S305AKSA1 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (α = 0.56 %/°C) enables inherent current sharing. Parallel operation requires matched gate drive impedance (<5 Ω difference), symmetrical PCB layout, and individual gate resistors (≥10 Ω) to suppress oscillation. Derate total current by 15% for thermal margin in multi-device arrays.

Is the body diode suitable for synchronous rectification in a 48 V buck converter?

Yes - with 0.6–1.2 V V_SD at 80 A and 108 ns t_rr, it delivers lower forward loss than discrete Schottky diodes above 40 A, and its soft recovery minimizes EMI. However, ensure gate drive timing accounts for 380 nC Q_rr to avoid cross-conduction; dead-time must exceed 200 ns at 200 kHz switching.
