HTZ120A51K

Diode Arrays Overview

The HTZ120A51K is a high voltage rectifier diode module from the IXYS HTZ120A series, rated for a repetitive peak reverse voltage of 51,000 V. It features a center-tap configuration with two silicon elements and supports a mean forward current of 2.0 A under air-cooled conditions at 35°C ambient temperature. The device has a maximum non-repetitive surge forward current of 200 A and operates within a virtual junction temperature range up to 180°C. Thermal resistance from junction to ambient is 2.3°C/W in air cooling applications.

Diode Arrays Procurement Notes

Verify component authenticity through authorized IXYS distributors or certified suppliers. Confirm datasheet revision matches the specific manufacturing batch. Ensure storage conditions remain within the specified -40 to 100°C range prior to installation. Validate packaging integrity to prevent physical damage to the ceramic isolation layer during transit and handling procedures.

Diode Arrays Selection Notes

Select this module when system requirements demand extreme reverse voltage blocking capability exceeding standard industrial levels. Evaluate thermal management strategies carefully, as air-cooled performance differs significantly from oil-cooled ratings. Ensure mounting hardware accommodates the three M6 tapped holes for reliable electrical grounding and mechanical stability during operation.

Diode Arrays Part Context

This component belongs to the HTZ120A series of high voltage diode modules manufactured by IXYS.
