HTZ270H56K

Diode Arrays Overview

The HTZ270H56K is a high-voltage diode rectifier module from the IXYS HTZ270H series, rated for a repetitive peak reverse voltage of 56,000 V and a minimum avalanche voltage of 60,000 V. It features a center-tap circuit configuration with a mean forward current of 3.4 A under air-cooled conditions at 35°C ambient temperature. The device supports a continuous direct forward current of 4.1 A in air cooling and operates within a virtual junction temperature range up to 180°C. Thermal resistance from junction to ambient is 0.95°C/W, while junction-to-oil resistance is 0.77°C/W for oil-cooled applications.

Diode Arrays Procurement Notes

Verify the specific part number suffix against official datasheets to confirm voltage ratings. Confirm thermal management requirements match either air or oil cooling specifications. Check RoHS compliance status as manufacturing processes may vary by production batch. Ensure chassis mounting hardware matches the specified M5 tapped holes and dimensional outlines provided in the manufacturer documentation.

Diode Arrays Selection Notes

Select this component when system design requires ultra-high reverse voltage blocking exceeding standard semiconductor limits. Evaluate thermal dissipation strategies carefully, as the module relies on external heat sinking via chassis mounting. Compare air-cooled versus oil-cooled current derating curves based on the intended operating environment. Ensure the center-tap configuration aligns with the specific rectifier topology required for the application.

Diode Arrays Part Context

This module belongs to the HTZ270H series, which encompasses various voltage ratings ranging from 40 kV to 64 kV. All variants share identical physical dimensions, thermal characteristics, and current ratings, differing only in their maximum repetitive peak reverse voltage and minimum avalanche voltage specifications. The series utilizes standardized chassis-mount packaging for consistent mechanical integration across different voltage levels.

Diode Arrays Replacement Considerations

Direct replacements must match the 56 kV voltage rating and 3.4 A current capacity. Verify that substitute modules support the same center-tap configuration and chassis mounting dimensions. Cross-reference thermal resistance values to ensure equivalent heat dissipation performance. Confirm that the replacement device meets the required surge current and frequency range specifications.
