HTZ130B24K

Diode Arrays Overview

The HTZ130B24K is a high-voltage silicon diode rectifier module from the IXYS HTZ130B series. It features a repetitive peak reverse voltage (VRRM) of 24,000 V and a continuous forward current rating of 1.0 A under air-cooled conditions at 35°C ambient temperature. The module utilizes a screw-mount installation style within an HTZ box package. Key electrical characteristics include a maximum forward voltage of 24.0 V at 2 Amps peak and a virtual junction temperature limit of 180°C. The device supports a frequency range of 20 to 400 Hz and includes surge current capabilities for non-repetitive applications.

Diode Arrays Procurement Notes

Verify component authenticity through authorized IXYS distributors or certified secondary market suppliers due to potential availability constraints. Confirm that the physical package dimensions and terminal configurations match the specific mechanical requirements of the target assembly. Ensure storage conditions remain within the specified -40 to 100°C range to maintain material integrity prior to installation.

Diode Arrays Selection Notes

Select this module when system designs require a single-diode solution for voltages exceeding standard semiconductor limits. Evaluate thermal management strategies carefully, as the device supports distinct ratings for air and oil cooling. Compare the 24 kV rating against actual circuit transients to ensure adequate safety margins. Consider the physical size and screw-mount requirements during PCB or chassis layout planning.

Diode Arrays Part Context

This component belongs to the HTZ130B series, which encompasses various high-voltage diode modules ranging from 24 kV to 38 kV. All members share identical current ratings and thermal characteristics, differing primarily in their breakdown voltage specifications. The series is engineered for industrial applications demanding high reliability and stable performance under extreme electrical stress conditions.

Diode Arrays Replacement Considerations

Direct replacements must match the 24 kV VRRM and 1.0 A IF(AV) ratings. Verify that alternative modules support the same HTZ package form factor and M4 tapped mounting holes. Cross-reference thermal resistance values if operating in oil-cooled environments to ensure equivalent heat dissipation performance.
