HTZ150C9K

Diode Arrays Overview

The HTZ150C9K is a high-voltage diode rectifier module from the IXYS HTZ150C series. It features a repetitive peak reverse voltage (VRRM) of 9600 V and a minimum avalanche voltage of 10200 V. The device supports a mean forward current of 3.0 A under air-cooled conditions and up to 6.5 A in oil-cooled environments. Key electrical characteristics include a maximum forward voltage of 6.0 V at 2 Amps peak and a peak reverse current of 0.5 mA at 150°C. The module utilizes a screw-mount installation style within an HTZ box package, with physical dimensions of 130 mm length, 32 mm width, and 31 mm height.

Diode Arrays Feature Summary

• Engineered for extreme high-voltage applications with a 9600 V repetitive peak reverse voltage rating.
• Capable of handling significant surge currents, including a non-repetitive forward surge of 100 A.
• Designed for versatile thermal management, supporting both air-cooled and oil-cooled operational modes.

Diode Arrays Applications

• High voltage DC power supply rectification
• Industrial motor drive systems
• Electrostatic precipitators

Diode Arrays Procurement Notes

Verify the specific suffix 'K' against official datasheets to confirm the 9600 V rating. Confirm mounting requirements for the three M5 tapped holes. Check for end-of-life status as distribution availability may be limited. Ensure thermal interface materials match the specified junction-to-ambient or junction-to-oil resistance values for your cooling method.

Diode Arrays Selection Notes

Select this component when system voltages exceed standard industrial levels but remain below ultra-high voltage thresholds. Compare thermal resistance values between air and oil cooling to determine the appropriate heat sink design. Verify that the 3.0 A continuous current rating meets the load requirements without exceeding the 180°C virtual junction temperature limit.

Diode Arrays Part Context

This module belongs to the HTZ150C series, which offers various voltage ratings ranging from 6000 V to 9600 V. The series shares identical physical dimensions and current ratings, differing primarily in the breakdown voltage specifications defined by the suffix. This allows designers to use standardized mechanical layouts while adjusting for specific voltage isolation needs.

Diode Arrays Replacement Considerations

Check for direct cross-reference part numbers from IXYS or Littelfuse. Verify that any substitute maintains the 9600 V VRRM and 3.0 A IF(AV) ratings. Ensure the replacement package matches the HTZ form factor and M5 mounting hole configuration.
