The Toshiba 30Q6P45 and 30U6P45 are silicon‑diffused, three‑phase full‑wave bridge rectifier modules intended for inverter equipment, chopper equipment, DC motor control, and other power‑conversion applications. The document lists maximum ratings, electrical characteristics, and thermal specifications to aid designers in selecting the appropriate part.
Key specifications include a repetitive peak reverse voltage of 1200 V (30Q6P45) or 1600 V (30U6P45), an average output rectified current of 30 A, isolation voltage of 2500 V AC for 60 s, and thermal resistance values of 0.8 °C/W (junction‑case) and 15 °C/W (junction‑ambient). Operating temperature ranges span –40 °C to 150 °C for the junction and –40 °C to 125 °C for storage.
