STMicroelectronics Announces the STPS60SM200C, New 200V Power Schottky Rectifier Diode

STMicroelectronics announced the STPS60SM200C, a new high-voltage Schottky diode that will help increase the energy efficiency and ruggedness of equipment such as telecom base stations and welding equipment.

ST’s new 200V power Schottky rectifier diode, the STPS60SM200C, will be used in high-current AC/DC power supplies delivering nominal DC output voltages in the 30-50V range. Its 200V maximum reverse voltage is compatible with known worst-case operating conditions and provides the design margins needed to withstand over-voltages and remain fully operational down to -40 degrees C, making it ideal for telecom base station sites anywhere in the world.

As one of very few 200V Schottky devices currently on the market, the STPS60SM200C integrates two interconnected diodes in a three-pin package to provide a more energy efficient alternative to ultra-fast diodes, which typically have higher conduction losses. Since approximately 30% of today’s base station designs still use traditional ultra-fast diodes, ST expects to convert a sizeable proportion of these applications to the new rugged devices, while offering an alternative source for high-end platforms already using Schottky devices.

Using ST proprietary process technology, the STPS60SM200C achieves over 2kV ESD-protection, which is higher than comparable Schottky devices when tested according to IEC 61000-4-2. This provides increased assurance of survivability against destructive threats such as high-voltage transients, significantly reducing equipment down-time as well as minimizing repair costs. These savings are particularly important for cellular base stations in remote locations, which are more time-consuming and expensive to reach and repair.

Key features of STPS60SM200C:

• Repetitive peak reverse voltage (V(RRM)): 200V
• Average forward current IF(AV): 2 x 30A
• Maximum operating junction temperature (T(j) (max)): 175 degrees C
• Forward voltage (V(F)): 640mV typical

Samples of the STPS60SM200C are available now in the industry-standard TO-247 case, priced at $2.436 per unit for one thousand units. Alternative pricing options may be available for higher quantities.
