ST Microelectronics ( ST ) has introduced a new high-voltage Schottky rectifier diode to help improve the performance and robustness of equipment such as telecom base stations and electric welders.
ST's new 200V power Schottky rectifier diode ST PS60SM200C targets high-current AC/DC power supplies with a DC output of 30-50V. The 200V maximum reverse voltage is compatible with the most demanding working (packaging) environments. The coefficient can withstand overvoltage and has a minimum operating temperature of -40 ° C, making it ideal for distribution to telecommunications base stations anywhere in the world.
As one of only a few 200V Schottky diodes on the market, the STPS60SM200C combines two interconnect diodes in a 3-pin package, making it an alternative to ultra-high-speed diodes with high on-state losses. In today's base station design, the usage rate of traditional ultra-high-speed diodes still reaches about 30%. Therefore, STMicroelectronics expects this new diode to be used in large-scale applications, providing high-end platform manufacturers that currently use Schottky diodes. A new product option.
The STPS60SM200C uses ST's unique manufacturing technology. Its electrostatic discharge (ESD) protection capability exceeds 2kV. It is tested according to IEC 61000-4-2 and its ESD protection capability is higher than that of similar Schottky diodes on the market. This protection enhances the survivability of new products in destructive security threats such as transient high voltages, dramatically reducing equipment downtime and minimizing equipment maintenance costs. Since the installation of mobile communication base stations in remote areas is time consuming and costly, these advantages are particularly important for mobile base station applications.
Main features of the STPS60SM200C:
• Repeated reverse peak pressure (VRRM): 200V
? Average forward current (IF(AV)): 2 x 30A
? Maximum working junction temperature (Tj (max)): 175 ° C
? Typical forward voltage (VF): 640mV
The STPS60SM200C is available in an industry standard TO-247 package and is available now.
