The document describes the features and characteristics of rectifiers, including parameters such as input and output voltage and current. It also provides a supplier search function.
The Semikron B‑series Si‑Bridge rectifiers (B 40FD to B 380FD) are fast‑switching devices with forward current ratings from 0.8 A to 1.0 A and reverse voltage capabilities ranging from 80 V to 800 V. Key features include a maximum solder temperature of 260 °C, UL recognition (file no. E63532), and standard plastic tube packaging.
Mechanical data show a compact plastic case of 8.3 × 6.4 × 3.1 mm and a weight of approximately 0.3 g. Electrical specifications list absolute maximum ratings such as a peak forward surge current of 40 A, reverse recovery time under 300 ns, and thermal resistance of 60 K/W (junction‑to‑ambient). Typical forward characteristics and temperature‑dependent current ratings are illustrated in the included graphs.
| Forward Current | 0.8 A – 1.0 A |
|---|---|
| Reverse Voltage | 80 V – 800 V |
| Maximum Solder Temperature | 260 °C |
| Case Dimensions | 8.3 × 6.4 × 3.1 mm |
| Weight | ≈ 0.3 g |
| Thermal Resistance (junction‑to‑ambient) | 60 K/W |
| Maximum Forward Voltage | 1.3 V |
| Maximum Leakage Current | 10 pA |
The devices are rated for a forward current between 0.8 A and 1.0 A depending on the specific model.
They support reverse voltages from 80 V up to 800 V.
The maximum solder temperature is specified as 260 °C.
The thermal resistance junction‑to‑ambient is 60 K/W.
