Product details
Overview
IPP77N06S212AKSA1 from Infineon Technologies is an N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, rated for 55 V VDS, 77 A continuous drain current at TC = 25 °C, and ultra-low 9.8–12.0 mΩ RDS(on) at VGS = 10 V. It is AEC-Q101 qualified, 100% avalanche tested, and supports automotive motor control and DC-DC converter primary-side switching.
For engineers reviewing the IPP77N06S212AKSA1 datasheet, IPP77N06S212AKSA1 pinout, IPP77N06S212AKSA1 application, or IPP77N06S212AKSA1 equivalent, key selection criteria include its 0.95 K/W junction-to-case thermal resistance, 280 mJ single-pulse avalanche energy, gate plateau voltage of 5.6 V, and operation up to 175 °C junction temperature in high-reliability power stages.
Technical Context
This OptiMOS® device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching performance. Its dynamic parameters include 1770 pF input capacitance (Ciss), 460 pF output capacitance (Coss), and 120 pF reverse transfer capacitance (Crss) at VDS = 25 V, enabling efficient hard-switched topologies.
The MOSFET features a gate threshold voltage range of 2.1–4.0 V and exhibits stable RDS(on) over temperature - increasing only ~2× from 25 °C to 175 °C - supporting robust gate drive design in thermally constrained environments such as engine bay-mounted power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - maximum blocking voltage compatible with 48 V automotive systems and 36 V industrial DC bus applications |
| RDS(on) max | 12.0 mΩ at VGS = 10 V, ID = 38 A - enables <1 W conduction loss at 77 A in optimized heatsink layouts |
| ID continuous | 77 A at TC = 25 °C - supports high-current motor phase legs and synchronous rectifier designs |
| EAS | 280 mJ single-pulse - provides margin against inductive turn-off transients in solenoid and relay drivers |
| RthJC | 0.95 K/W - allows direct mounting to heatsinks with predictable thermal path for thermal design validation |
| Qg total | 60 nC max - determines gate driver power requirement and switching loss trade-off in 100–200 kHz converters |
| VGS(th) | 2.1–4.0 V - ensures reliable turn-on with standard 5 V logic-level gate drivers and noise immunity above 1 V |
Pinout & Package
IPP77N06S212AKSA1 is housed in PG-TO220-3-1 package with isolated tab (drain-connected). The case is electrically connected to the drain terminal and must be mounted to a grounded heatsink with appropriate insulation if required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for load current | Low-inductance source connection critical for minimizing shoot-through risk in half-bridge configurations |
| 2 (Gate) | Control electrode for channel formation | Requires <60 nC gate charge; sensitive to ESD - needs series resistor and TVS protection in layout |
| 3 (Drain) | Main power output / high-side switch node | Connected to metal tab; requires thermal interface material and mechanical clamping for optimal heat transfer |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per ISO/TS 16949 |
| 100% avalanche tested | Each unit subjected to single-pulse inductive switching stress at rated current - guarantees ruggedness in unclamped inductive loads |
| Ultra-low RDS(on) | 9.8 mΩ typical at 25 °C enables >96% efficiency in 12 V/77 A DC-DC stages with minimal heatsinking |
| 175 °C operating temperature | Enables placement in high-ambient zones (e.g., near engines or inverters) without derating below 77 A at TC ≤ 100 °C |
| Green package | Lead-free, RoHS-compliant construction with MSL1 rating - supports lead-free reflow up to 260 °C peak |

FAQ
Is IPP77N06S212AKSA1 pin-compatible with IPP77N06S2-12?
Yes - IPP77N06S212AKSA1 is the full ordering code for the same device previously referenced as IPP77N06S2-12 in early documentation. The "KSA1" suffix denotes packaging and reel configuration per Infineon's current coding system; electrical, thermal, and mechanical specifications are identical.
What is the maximum safe operating temperature for continuous 77 A drain current?
At 77 A continuous drain current, the junction temperature must not exceed 175 °C. With RthJC = 0.95 K/W, this requires case temperature ≤ 99 °C - achievable using a properly sized heatsink with thermal resistance ≤ 0.7 K/W to ambient under forced airflow or ≤ 0.3 K/W in natural convection with large finned extrusion.
Does this MOSFET require a gate resistor for automotive applications?
Yes - a gate resistor (typically 5–22 Ω) is required to dampen ringing, limit peak gate current, and control dV/dt during switching. In automotive environments, a 10 Ω series resistor combined with a 12 V Zener clamp to ground protects against load dump transients and ensures gate voltage stays within ±20 V absolute maximum rating.
Can IPP77N06S212AKSA1 replace a 60 V MOSFET in a 48 V battery system?
Yes - its 55 V VDS rating provides sufficient margin for 48 V nominal systems, including worst-case transients up to 60 V (e.g., ISO 7637-2 Pulse 1/2/5a). However, it must not be used in 60 V nominal or higher systems without verifying transient clamping and derating curves from the datasheet's SOA graph.
