BY228 High-Voltage Damper Diode – 3A 1500V (2 Piece Set)

Product Overview

The BY228 is a specialized ‘Damper Diode’ engineered for the extreme electrical stress of deflection circuits. In a CRT display, the horizontal output stage creates massive voltage flybacks that could easily destroy standard transistors. The BY228 acts as a fast-acting clamp, ‘damping’ these transients and protecting the horizontal output transistor (HOT). With its massive 1500V rating and 3A current capacity, it is one of the most robust display protection components ever made.

Key Features

• Horizontal Damper Function: Specifically tuned for deflection circuits.
• 3.0 Amp Current Rating: Handles significant inductive loads.
• 1500V Ultra-High Voltage: Built for extreme flyback transients.
• Fast Soft-Recovery: Prevents electrical ringing and noise in the image.
• 2 Piece Set: Specialized pack for high-voltage display repair.

Benefits

Using the BY228 ensures that your high-voltage repairs are stable and that the horizontal output stage is fully protected. It prevents the costly failure of Flyback transformers and horizontal transistors. For specialized monitor technicians, this is a ‘must-have’ part for restoring older, high-quality equipment. This 2-piece pack provides a reliable supply for professional maintenance. Experience the security of industrial-strength damping technology.
