Overview
The BY12 is a standard recovery high voltage rectifier diode manufactured by Diotec Semiconductor. It features a repetitive peak reverse voltage (VRRM) of 12000 V and a surge peak reverse voltage (VRSM) of 12000 V. The maximum forward current (IFAV) is rated at 0.5 A, with a peak forward surge current (IFSM) of 30 A. Forward voltage (VF) is less than 10.0 V at 0.5 A. Leakage current is under 1 µA at 25°C and under 25 µA at 100°C when VR equals VRRM. Thermal resistance from junction to ambient is less than 25 K/W. Operating and storage temperatures range from -50°C to +150°C.
Feature Summary
- Capable of handling extreme voltages up to 12 kV for high-voltage rectification applications
- Features large creepage and clearance distances for enhanced safety in commercial grade designs
- Compliant with RoHS directives excluding exemption 7a-I, REACH regulations, and conflict minerals requirements
Applications
- High voltage rectification at 50/60 Hz
- Commercial grade power supply circuits
- Industrial equipment requiring standard reliability levels
Procurement Notes
Verify the specific datasheet version before finalizing designs, as Diotec reserves the right to modify product information without notice. Confirm that the component meets the required commercial or industrial grade standards for your intended application. Ensure compliance with RoHS exemptions and REACH regulations relevant to your region. Check for any export control restrictions if applicable to your location.
Selection Notes
Select the BY12 when a high voltage rating of 12 kV is required alongside a moderate continuous current capacity of 0.5 A. Consider its thermal characteristics and ensure adequate heat dissipation given the thermal resistance specifications. Evaluate the package dimensions and lead spacing to fit the mechanical constraints of the target circuit board layout effectively.
Part Context
The BY12 belongs to the BY4 through BY16 series of standard recovery high voltage rectifier diodes produced by Diotec Semiconductor. This family offers various voltage ratings ranging from 4 kV to 16 kV, catering to different high-voltage rectification needs. These components are designed for commercial and industrial applications where standard reliability is sufficient.
FAQ
What does the green ring on the BY12 indicate?
The green ring marks the cathode end of the diode and identifies it as a high voltage rectifier.
Is the BY12 suitable for automotive applications?
No, the BY12 is designated for commercial and industrial use. Automotive applications require AEC-Q101 qualified parts, which this component is not.
