(a high-power capsule-type thyristor often referenced as R2619ZC25J / distributed gate SCR) key features and product applications based on available datasheet and industry information: Key Features Electrical & Package Characteristics High Power Ratings: • Average on-state current ~ 2, 600 – 2, 700 A (depending on specific datasheet conditions) and **repetitive peak off-state voltage ~ 2500 V. Fast Switching: • Turn-off time (~ t₍q₎) ≈ 50 µs enables use in dynamic power applications. High Surge Capability: • Very high non-repetitive surge current capacity (~ 33 800 A). Distributed Gate Design: • Unique design provides high critical di/dt capability, fast recovery switching, and a low on-state voltage drop which improves efficiency in power circuits. Low Static & Dynamic Losses: • Helps reduce wasted energy and heat in conduction and switching cycles. Robust Physical Package: • Large capsule / disc style for high current and high power dissipation (often requiring heatsinking).
