SIC POWER MODULE Microchip introduces BZpack SiC power modules for high-demand applications

Microchip Technology announced its BZPACK mSiC power modules, designed to meet stringent High Humidity High Voltage High Temperature Reverse Bias (HV‑H3TRB) standards. The BZPACK modules can deliver exceptional reliability, streamline manufacturing and offer versatile system‑integration options for the most demanding power‑conversion environments.

Tested to meet HV-H3TRB standards that exceed the 1,000-hour standard, the BZPACK mSiC power modules provide confidence for deployments in industrial and renewable energy applications. With a Comparative Tracking Index (CTI) 600V case, stable Rds(on) across temperature ranges and substrate options in Aluminum Oxide (Al₂O₃) or Aluminum Nitride (AlN), the modules provide superior insulation, thermal management and long-term durability.

“The launch of our BZPACK mSiC power modules reinforces Microchip’s commitment to delivering rugged high‑performance solutions for the most demanding power‑conversion environments,” said Clayton Pillion, vice president of Microchip’s high-power solutions business unit. “By leveraging our advanced mSiC technology, we’re giving customers a simpler path to building efficient, long‑lasting systems across industrial and sustainability markets.”

To streamline production and reduce system complexity, BZPACK modules feature a compact, baseplate-less design with Press-Fit, solderless terminals and optional pre-applied Thermal Interface Material (TIM). These versatile options enable faster assembly, improved manufacturing consistency and easier multi- sourcing through industry standard footprints. Additionally, the modules are designed to be pin compatible for ease of use.

Microchip’s MB and MC families of mSiC MOSFETs offer robust solutions for both industrial and automotive applications, with AEC-Q101 qualified options available. These devices support common gate-source voltages (VGS ≥ 15V) and are offered in industry-standard packages for ease of integration. Proven HV-H3TRB capability supports long-term reliability by helping reduce risk of field failures due to moisture-induced leakage or breakdown. The MC family integrates a gate resistor, delivering improved switching control, maintaining low switching energy and improved stability in multi-die module configurations. Current options are available in TO-247-4 Notch and die form (waffle pack).
