BYM359X-1500,127

Diode Arrays Overview

The BYM359X-127 is a dual fast high-voltage rectifier diode in an isolated SOT186A package. It integrates damper and modulator functions for horizontal deflection circuits operating between 16kHz and 56kHz. The damper section supports a peak repetitive reverse voltage of 1500V, an average forward current of 10A, and a maximum non-repetitive surge current of 66A. The modulator section provides 600V reverse voltage capability with 8A average current. Key electrical parameters include a maximum reverse recovery time of 300ns for the damper and 145ns for the modulator.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify that the ordering suffix matches the specific packaging requirements. Confirm the device meets the required isolation voltage specifications for the intended application environment. Ensure compatibility with the thermal management design regarding the isolated mounting tab. Check for compliance with relevant safety standards if used in certified equipment.

Diode Arrays Selection Notes

Select this component when high-voltage isolation is required within a single package for deflection circuits. Compare the damper and modulator current ratings against the circuit's RMS and average load requirements. Consider the thermal resistance values to ensure adequate heat dissipation without compromising the isolation barrier.

Diode Arrays Part Context

This part belongs to the Philips Semiconductors (now NXP) family of fast, high-voltage dual diodes. It is designed as a combined damper and modulator solution, replacing discrete components to save board space. The SOT186A package allows for direct mounting to heatsinks while maintaining electrical isolation.

Diode Arrays Replacement Considerations

Check datasheets for other BYM series variants or equivalent dual diodes with matching reverse voltage and current ratings. Verify that replacement parts maintain the same isolated tab configuration and pinout compatibility.
