Hitachi Energy StakPak Press-pack IGBT Modules: The Core Engine of Energy Transmission

In high-voltage and high-reliability scenarios such as high-voltage power transmission and distribution, the performance of IGBT modules directly determines the energy efficiency and reliability of the system. Hitachi Energy's StakPak series, with its ultra-high specifications of 4500V blocking voltage and 1300 - 3000A continuous current, has become the "core component" for megawatt-level energy conversion. Its unique explosion-resistant packaging design and fail-safe mechanism provide "zero single-point failure" protection for critical facilities.

Limit parameters: Break through the industry ceiling

1. Voltage/Current Peak Values

·The entire series supports a blocking voltage of 4500V (e.g., 5SNA 3000K452300).

·The peak current reaches 6000A (Tp = 1ms) (5SNA 3000K452300).

·The surge current is 32kA (Tp = 10ms) (5SNA 2000K450300).

2. Thermal Management Limits

·Junction temperature: 150°C (short - term) / 125°C (continuous).

·The thermal resistance is as low as 0.0032K/W (IGBT chip - housing, 5SNA 3000K452300).

3. Mechanical Strength

·The installation pressure tolerance is 60 - 130kN (self - adapting to uneven surfaces).

Technological Highlights: Three Innovations Define the Industry Benchmark

1. SPT + Chipset technology

·Low-loss chip: The on-state voltage drops to 2.7V (IC = 1300A/Tvj = 25°C) (5SNA 1300K450300)

·Smooth switching characteristics: Optimize EMC performance and reduce electromagnetic interference in the system.

2. Active safety protection

·Fault short-circuit locking: Automatically enter a stable short-circuit state after a fault (standard for all series).

·Explosion-resistant packaging: Pass the mechanical shock test, and the explosion-proof level exceeds the industrial standard.

3. Intelligent thermal management

·Precisely controllable thermal impedance model: Support transient thermal resistance analysis.

·Dual-path heat conduction: The thermal resistance from the chip to the housing to the radiator is ≤ 0.005K/W.
