With leading silicon and packaging technologies, ON Semiconductor offers best-in-class IPM with a lineup of power levels from 20 W to 10 kW for industrial, automotive and consumer applications with significant energy efficiency, size, cost and reliability. Sexual advantages.
Depending on the application requirements, IPM can use a variety of different wafer technologies such as planar MOSFETs, super-junctions, field-stop IGBTs, silicon carbide (SiC), gallium nitride (GaN), etc., as well as packaging technologies such as flat no-pin (QFN). ), Full Pack, Ceramic Substrate, AI2O3, Aluminum Nitride (AIN), Insulated Metal Substrate Technology (IMST), Direct Bonded Copper (DBC), Single In-Line (SIP), Two-in-One (PFC +) Inverter inverters, etc., to minimize thermal resistance, reduce conduction loss and switching loss, while ensuring high integration, high switching speed, high energy efficiency, high reliability and excellent EMI performance.
600 V and 1200 V high power industrial IPM solutionsIndustrial IPM is mainly used in industrial compressors, pumps, variable frequency drives, power tools, etc. It is estimated that the compound annual growth rate (CAGR) of such markets in the next three years is 5.1%, which is growing rapidly. This is mainly due to the increasing demand for automation due to the rising labor costs, and various energy regulations and test standards such as ErP, IEC, GB3 and other requirements for energy efficiency are becoming stricter.
ON Semiconductor is one of the best suppliers in the market to offer both 600 V and 1200 V high-power IPM solutions. The main series are SPM45, SPM3, SPM2, and SIP series. In addition to the existing third- and fourth-generation field-stop IGBT technology, modules using SiC and GaN will soon be introduced.
The SPM3 series is mainly used in high-power air conditioners, industrial frequency converters, industrial pumps and industrial fans. These modules integrate the built-in IGBT optimized gate drive and use Al2O3 ceramic substrate for extremely low thermal resistance to optimize EMI performance and minimize Loss, while providing a variety of protection features such as undervoltage lockout, overcurrent shutdown, and fault reporting. The built-in high-speed HVIC only requires a single supply voltage and converts the received logic-level gate input signal into a high-voltage, high-current drive signal that effectively drives the module's internal IGBT. Among them, the 1200 V series is mainly for 3-phase inverter applications that require miniaturization. Currently, the FSBB10CH120D is mass-produced, and the rated output is 10 A. The models with rated output of 15 A and 20 A will be introduced later. The 600 V series covers a wider power range and is currently available from 15 A to 30 A, such as the FSBB15CH60D (15 A), FSBB20CH60D (20 A), and FNB33060T (30 A). The IPM of the same package has been expanded to 50 A.
Compared to the SPM3 series, the SPM2 series has a larger footprint, a lower thermal resistance and a wider power range. The 1200 V series includes FNA21012A (10 A), FNA22512A (25 A), and FNA23512A (35 A) to meet miniaturization requirements and high voltage trends. The 600 V series, such as the FNA23060 (30 A), FNA25060 (50 A), and FNA27560 (75 A), are more suitable for applications that require higher reliability and are less sensitive to volume.
The compact single in-line package (SIP) IPM series puts control, drive and output on one side, saving space and improving heat dissipation.
