The ESAC39M(C,N,D) is a fast‑recovery, low‑voltage drop diode offered by Fuji. It features an insulated fully‑molded package, very high switching speed, low turn‑on voltage and high reliability, making it suitable for high‑speed power‑switching applications.
The datasheet lists maximum ratings such as a 400 V repetitive peak reverse voltage, 600 V non‑repetitive peak reverse voltage, 1500 V isolating voltage, 2.5 V forward voltage drop at 2 A, 50 ns reverse recovery time, 3.5 °C/W thermal resistance, and a 5 A forward current rating. Additional parameters include surge current capability and junction capacitance. This manual is written in Japanese.
