The Diotec Semiconductor BY6 is a standard recovery high voltage rectifier diode designed for commercial grade applications. It features a repetitive peak reverse voltage (VRRM) of 6000 V and a surge peak reverse voltage (VRSM) of 6000 V. The maximum forward current (IFAV) is rated at 1.0 A, with a peak forward surge current (IFSM) of 30 A. Forward voltage (VF) is less than 6.0 V at 1.0 A. Leakage current is under 1 µA at 25°C and 25 µA at 100°C when VR equals VRRM. Thermal resistance junction to ambient is less than 25 K/W. Operating junction temperature ranges from -50°C to +150°C.
Verify component authenticity by checking for the specific green ring marking on the axial package which indicates the cathode side. Confirm that the reel label contains the correct type designation as markings are not printed directly on the case body. Ensure compliance with RoHS exemptions and REACH standards matches project requirements before finalizing procurement orders.
Select this component for high voltage DC conversion where standard recovery characteristics are sufficient. Consider the thermal derating curve if operating above 25°C ambient temperature. Verify lead spacing and axial dimensions fit the PCB layout constraints. Evaluate leakage current limits at elevated temperatures for critical low-current applications.
This part belongs to the BY4 through BY16 series of standard recovery high voltage rectifiers manufactured by Diotec Semiconductor. These components utilize an axial glass passivated junction construction housed in a UL 94V-0 rated case material. The series covers voltages from 4 kV to 16 kV with currents ranging from 0.3 A to 1.0 A.
Direct substitutes include other BY6 equivalent parts from different manufacturers offering identical 6000 V rating and 1.0 A current capacity. Verify pinout orientation and physical dimensions match the existing design footprint before substitution.
