The High-Power Press-Pack Capsule Rectifier Diode (Part Number: 2000022) supplied and certified by premier Italian power electronics manufacturer SECOM s.r.l. is an industrial-grade semiconductor designed for extreme current-carrying duty in heavy-duty AC/DC rectification systems. It provides continuous forward currents up to 3400A and blocking voltages up to 2600V.

PRODUCT SPECIFICATIONS & FEATURES (PART NO: 2000022):
- Part Number: 2000022
- Manufacturer: SECOM s.r.l. (Italy)
- Device Category: Press-Pack / Hockey-Puk High-Power Rectifier Diode
- Mean Forward Current ($I_{FAV}$): 3400 A (under standard industrial double-side cooling conditions).
- Repetitive Peak Reverse Voltage ($V_{RRM}$): 2600 V, providing superior immunity against grid transients, lightning surges, and inductive load switching overvoltages.
- Ceramic Capsule Housing: Hermetically sealed ceramic disc housing with precision flat nickel-plated copper pole faces, offering extended creepage and clearance distances to prevent surface flashovers in humid and dusty environments.
- Double-Side Cooling Architecture: Designed for mounting between two high-efficiency forced-air or liquid-cooled aluminum heatsinks, facilitating immediate thermal conduction away from the silicon wafer junction.

KEY ADVANTAGES:
- High Surge Current Capability (High $I_{FSM}$ / $I^2t$): Engineered to withstand severe short-circuit fault conditions and heavy inrush spikes characteristic of arc furnaces and heavy motor drives.
- Low Forward Voltage Drop ($V_{FM}$): Minimizes internal conduction losses, reducing operating temperatures and maximizing overall electrical efficiency in high-current converter bridges.
- Direct Compatibility with SECOM Power Stacks: Seamlessly integrates into SECOM GR.6 modular bridges, custom electrolysis rectifiers, and medium-voltage industrial converters as a reliable drop-in replacement.
