Packaged in a robust TO-247 through-hole case, this device leverages TrenchT2 technology to achieve a balance of low conduction loss, high current capability, and ease of integration into power electronics systems. With a rated drain-to-source voltage (Vds) of 55V and a continuous drain current capability of 260A (measured at case temperature), the IXTH260N055T2 is suitable for a variety of high-reliability power switching and conversion environments.

Essential Electrical Parameters of the IXTH260N055T2

The electrical profile of the IXYS IXTH260N055T2 places it among the preferred choices for engineers seeking efficient, high-current silicon-based switches. Notably, the device provides a maximum Rds(on) of only 3.3 milliohms when operated at Vgs = 10V and Id = 50A, allowing for minimal conduction loss and higher efficiency in system design. The device’s maximum gate threshold voltage (Vgs(th)) sits at 4V, with gate charge (Qg) reaching up to 140nC at Vgs = 10V, which yields predictable gate drive requirements—important for power supply and motor control circuits.

The input capacitance (Ciss) is measured at 10800 pF (at Vds = 25V), which informs gate driver selection and influences switching speed. These characteristics underscore the IXTH260N055T2’s suitability for applications where fast switching and efficient thermal management are critical.

Thermal Properties and Mechanical Details of the IXTH260N055T2

Thermal performance is a key specification in high-power devices. The IXYS IXTH260N055T2 is rated for a maximum power dissipation of 480W when mounted to an appropriate heat sink and measured at the case (Tc). The device’s operating junction temperature range spans from -55°C to +175°C, enhancing its reliability in environments with significant temperature fluctuations.

From a mechanical perspective, the device adopts the industry-standard TO-247 package, providing reliable through-hole mounting for high-current traces and ease of integration in power modules. The ruggedized package supports optimal heat transfer to system cooling solutions, essential for continuous high-load operation.

Use Cases and Design Guidelines for the IXTH260N055T2

The IXYS IXTH260N055T2 is engineered for use in high-current switching and power conversion environments such as motor drives, high-frequency inverters, DC-DC converters, and robust industrial load switches. In these scenarios, the device’s low Rds(on) reduces I²R losses during operation, and its high current handling maximizes load capability per device.

For engineers, selection criteria should include careful consideration of gate drive capability due to the relatively high gate charge and capacitance values. Proper heat sinking is also vital to ensure reliability, particularly when pushing the device close to its 260A drain current or 480W power dissipation maxima. Simulated thermal models and empirical measurements are recommended during system validation to ensure compliance within safe operating areas.

IXYS IXTH260N055T2 Environmental Standards and Reliability

Ensuring device compliance with global standards is critical, especially for products deployed in regulated markets. The IXYS IXTH260N055T2 fulfills RoHS3 compliance, indicating its construction is free from hazardous materials, and is classified at Moisture Sensitivity Level (MSL) 1, allowing unlimited storage life under defined conditions. The device also meets REACH standards, ensuring its suitability for use in environmentally conscious and export-sensitive applications, without restrictions on its commercial adoption.

Alternative or Substitute Models for the IXYS IXTH260N055T2

When integrating or replacing the IXYS IXTH260N055T2 in new or legacy designs, engineers should focus on devices with a similar package (TO-247), maximum drain-to-source voltage (55V), and continuous drain current (approximately 260A). Key parameters such as Rds(on), power dissipation, and gate charge must align closely to ensure seamless replacement without compromising system performance. Consultation of broader MOSFET product lines across the industry—especially equivalents from manufacturers specializing in high-current, low-voltage devices—is recommended when considering form, fit, and function replacements for the IXTH260N055T2.
