SKN SKR series high-performance power supply modules are designed for switching power supplies. They are available in a wide range of power and voltage ratings.
The SKN 26 datasheet describes a hermetically sealed metal‑case rectifier diode with a glass window. It lists key features such as an operating temperature range of –40 °C to +180 °C, reverse voltage capability up to 1600 V, and recommended snubber network values. Typical applications include mean‑power rectifier diodes, non‑controllable and half‑controllable rectifiers, and fire‑wheel‑induced diodes.
The document contains detailed electrical and thermal characteristics, including forward voltage at 180 °C (max 0.85 V), maximum continuous forward current (40 A), and various graphs of power dissipation versus forward current, case temperature, and transient thermal impedance. It also provides mechanical details such as an ISO M6 threaded stud and mounting options.
| Maximum continuous forward current | 40 A |
|---|---|
| Maximum forward voltage at 180 °C | 0.85 V |
| Maximum reverse voltage | 1600 V |
| Operating temperature range | -40 °C to +180 °C |
| Recommended snubber network | RC 0.05 nF, 200 Ω (1 W); R 150 kΩ (4 W) |
The SKN 26 can handle up to 40 A of continuous forward current.
The device is rated for reverse voltages up to 1600 V.
A snubber consisting of RC = 0.05 nF, 200 Ω (1 W) and R = 150 kΩ (4 W) is recommended.
