30 PRODUCT UPDATE Issue 4 2023 Power Electronics Europe www.power-mag.com help to maximise power density, reducing the amount of required board space and lowering the overall system cost. Thermal performance is optimised using a combination of top-side cooling (TSC) and an integrated negative temperature co-efficient (NTC) sensor which monitors the device temperature and provides real time feedback for device or system level prognosis and diagnosis. The rectifier module has a low inductance package to enable high frequency operation and has been qualified to operate with a junction temperature of up to 175°C. According to Katrin Feurle, Senior Director of the Product Group SiC at Nexperia, the collaboration combines the company’s SiC semiconductors with module packaging for products which offer “exceptionally high levels of power density”. The module is the first step in what is envisaged as a long-term SiC partnership between Nexperia and Kyocera AVX. Thomas Rinschede, Deputy Vice President Sensing and Control Division at Kyocera AVX Components Sensing and Control Division, comments: “We are delighted to further extend our successful partnership with Nexperia into the production of silicon carbide modules for power electronics applications . . . Nexperia’s manufacturing expertise combined with Kyocera module know-how make a compelling offering for customers looking to achieve higher power densities using wide bandgap semiconductor technology.” Nexperia expects samples of the new SiC rectifier modules to be available in Q1 2024. The PhotoMOS SOP4 AQY212G3HS and AQY232G3HS relays operate at up to 105°C and 125°C respectively. They can be used in higher temperature environments including modern industrial equipment, testing, and measuring equipment as well as security and battery operating equipment. The compact SOP4 package achieves an I/O withstand voltage of 3,750V rms, allowing for insulated equipment to be miniaturised. The AQY232G3HS components achieve high-capacity 2A load control and the AQY212G3HS relays have 1.8 A load control. The AQY232G3HS components achieve a maximum LED current of 1mA, which is one third that of conventional models, says the company, enabling an LED current during use to be reduced by up to 40% to lower power consumption. The AQY232G3HS models achieve an average of 0.8ms, which is about 57% the time required for conventional models, says Panasonic Industry. The increased speed of the switching operation improves the tact time of equipment and systems. SOP4 60V MOSFET relays operate in high temperatures Ultra-low VRWM TVS diode provides USB4 and Thunderbolt 4 ESD protection The AOZ8S207BLS-01 ultra-low reverse working voltage (VRWM) transient voltage suppressor (TVS) diode. It is designed to deliver low capacitance and fast response times, with high speed data line protection based on AOS’ UltraLow Breakdown Voltage (VBR) TVS platform and packaging. Together with the TVS diode’s 0.15pf capacitance, it is suitable for USB4 and Thunderbolt 4 electrostatic discharge (ESD) protection. Low breakdown voltage is essential for ESD protection devices, especially when protecting ICs manufactured with the finest process, explains the company. This TVS diode features an especially low breakdown voltage, and it can provide a faster response time compared to conventional snap-back devices, enabling it to absorb ESD energy extremely quickly to avoid damage to the IC and surrounding components. The single-channel device is housed in a 0.6 x 0.3mm leadless surfacemounted device (SMD) package which makes it well-suited to meet the small footprint requirements of USB Type-C connectors, adds the company. According to AOS’ marketing director, Charles Chen, the AOZ8S207BLS-01 provides “a much better figure of merit (FOM) on clamping voltage times capacitance”. “In addition to low capacitance, having a lower clamping voltage and faster response during an ESD event is important to protect today’s more ESDsensitive chipsets,” and help designers to “greatly reduce ESD failure rates in their electronic products”. The AOZ8S207BLS-01 TVS diode is immediately available in production quantities with a lead time of 16 weeks.
