3PFT05 3PFT1 3PFT15 3PFT2
The 3PFT series rectifier diodes are axial‑lead, hermetically sealed devices designed for fast switching applications. They offer very low reverse recovery time (30 ns), low forward voltage drop (≈1.05 V at 3.5 A), and low switching losses.
Key electrical ratings include a working reverse voltage of 50‑200 V, an average forward current of 4 A, and surge current capabilities of 25 A (repetitive) and 90 A (non‑repetitive). Thermal performance is defined by a junction‑to‑lead resistance of 26 °C/W (0.375" lead) and a junction‑to‑ambient resistance of 75 °C/W. The devices operate from –65 °C to +175 °C and are qualified to European DEF STAN 59‑61 standards.
