Product details

Overview

IPP77N06S212AKSA2 from Infineon Technologies is an N-channel enhancement-mode automotive-qualified MOSFET in PG-TO220-3-1 package, rated for 55 V V_DS, 77 A continuous drain current at T_C = 25 °C, and ultra-low 9.8–12.0 mΩ R_DS(on) at V_GS = 10 V. It operates up to 175 °C, is 100% avalanche tested, and is used in high-efficiency DC-DC converters and motor control stages in automotive body electronics.

For engineers reviewing the IPP77N06S212AKSA2 datasheet, IPP77N06S212AKSA2 pinout, IPP77N06S212AKSA2 application, or IPP77N06S212AKSA2 equivalent, key selection criteria include R_DS(on) at 10 V gate drive, thermal resistance (R_thJC = 0.95 K/W), avalanche energy rating (280 mJ), and AEC-Q101 qualification status for under-hood power switching.

Technical Context

This OptiMOS® device employs trench-gate superjunction technology optimized for low conduction and switching losses in hard-switched 12 V automotive systems. Its gate threshold voltage (2.1–4.0 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity, and its 1770 pF input capacitance supports predictable gate drive design with standard 6.2 Ω gate resistors.

The integrated body diode exhibits 0.9–1.3 V forward voltage at 77 A and 45–60 ns reverse recovery time, enabling synchronous rectification and freewheeling operation in buck converters and H-bridge motor drivers without external diode supplementation.

Key Specifications

Q_g total	45–60 nC - Determines gate driver power requirement and switching speed trade-off in 100–500 kHz applications.
V_GS(th)	2.1–4.0 V - Ensures reliable turn-on with 3.3 V or 5 V logic while avoiding spurious activation from noise.
T_j max	+175 °C - Rated for under-hood environments including engine control units and battery disconnect modules.

Pinout & Package

IPP77N06S212AKSA2 uses the PG-TO220-3-1 package: insulated tab, vertical mounting, lead-free plating, MSL1 rated for 260 °C peak reflow. The case is electrically connected to the drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for drain current	Low-inductance connection point for PCB ground plane or source bus; ties to internal substrate.
2 (Gate)	Control electrode for channel formation	High-impedance input requiring low-noise routing; sensitive to ESD and ringing above 20 V absolute max.
3 (Drain)	Main power output / high-side switch node	Connected to metal tab; must be isolated from heatsink unless using insulating pad; carries full load current.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements including HTGB, HTRB, and temperature cycling.
100% avalanche tested	Each unit undergoes single-pulse unclamped inductive switching at rated I_D to guarantee ruggedness in real-world fault conditions.
Ultra-low R_DS(on)	Reduces conduction losses by >30% vs. legacy TrenchMOS in same package, directly improving efficiency in 12 V battery-fed systems.
Green package	Lead-free, halogen-free construction compliant with RoHS and ELV directives; no post-soldering cleaning required.
Optimized dynamic parameters	C_iss/C_oss ratio of ~3.8 enables stable hard-switching behavior with reduced voltage overshoot during turn-off.

Applications

Use Value: TO-220 package allows direct bolt-down heatsinking; 100% avalanche test guarantees survival during stalled-rotor faults.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB77N06S212AKSA2	PG-TO263-3-2 package, lower R_thJA on PCB (40 K/W with 6 cm² copper)	Better suited for SMD-based automotive modules with limited board space	Select when surface-mount assembly and enhanced PCB thermal performance are required.
IPP77N06S205AKSA2	Lower R_DS(on) (max 5.0 mΩ), same V_DS and package	Higher cost; requires tighter gate drive control due to lower V_GS(th) (1.8–3.2 V)	Choose for ultra-high-efficiency 12 V systems where <0.5 W conduction loss is critical.

Compared with IPB77N06S212AKSA2 and IPP77N06S205AKSA2, IPP77N06S212AKSA2 balances cost, thermal performance, and drive simplicity-making it optimal for mechanically mounted, high-reliability automotive switches where TO-220 form factor and proven field history are prioritized.

FAQ

Is IPP77N06S212AKSA2 pin-compatible with IPP77N06S205AKSA2?

Yes-both use identical PG-TO220-3-1 packaging and share identical pinout (Drain–Gate–Source). However, the 05 variant has lower R_DS(on) and slightly different V_GS(th), so gate drive design and thermal margin should be revalidated despite mechanical interchangeability.

What is the maximum recommended gate resistor value for 250 kHz switching?

For 250 kHz operation with typical 6.2 Ω gate driver output impedance, a series gate resistor of 5–10 Ω is recommended to limit peak current and damp ringing. This yields ~35 ns effective rise/fall times based on Q_g = 52.5 nC and V_GS swing of 10 V.

Does this MOSFET require a negative gate turn-off voltage?

No-its V_GS(th) range (2.1–4.0 V) and ±20 V absolute maximum rating allow safe operation with 0 V turn-off. Negative bias is unnecessary and not implemented in standard automotive gate drivers for this device family.

Can IPP77N06S212AKSA2 replace older SIPMOS devices like BSP77N06LS3G?

Yes-though BSP77N06LS3G is obsolete, IPP77N06S212AKSA2 matches its V_DS, I_D, and TO-220 footprint while offering lower R_DS(on), higher temperature rating (175 °C vs. 150 °C), and AEC-Q101 qualification-making it a direct functional upgrade.
