World's First Industry-Standard Certified Automotive Overvoltage Protection Device Launched
Published2012.08.13 10:57• World's first ultra-compact Transil™ (TVS) device compliant with automotive industry standard ISO pulse specifications
• Reduction in final approval time and cost reduction for precision automotive electronic devices
August 13, 2012, Seoul – STMicroelectronics (ST), a global semiconductor company providing a wide range of electronic applications, is offering a new overvoltage protection device that meets automotive industry standards. This is expected to enable manufacturers of precision automotive electronics to implement safer and more reliable systems. In particular, this product will help shorten time-to-market and improve price competitiveness by saving time required for individual certifications.
Overvoltage protection refers to preventing voltage pulses generated in vehicle wiring from damaging sensitive subsystems, such as safety systems, control modules, and infotainment equipment. Pulses can occur in various situations, including electrostatic discharge from occupants, the switching on/off of subsystems like motor drives or climate control, or load dumps such as when the battery suddenly shuts off. Until now, design engineers have selected industry-standard devices for specific pulses, but it has been difficult to consider these specific pulses as representative of all pulses occurring in a vehicle.
ST's new compact Transil overcurrent protection device SM4TY-SM30TY series has been certified for pulse specifications used by the automotive industry. In addition, the product complies with AEC-Q101, the automotive reliability test standard for discrete semiconductors, and has obtained the Automotive Grade Certification Certificate (AGAC). Therefore, engineers can reduce the time spent selecting devices between industrial and automotive standards and individually re-certifying each new subsystem design, thereby shortening the time to market for new products and increasing cost efficiency.
Transil protection devices are supplied in small surface-mount power packages that occupy only 12.8mm2 to 46mm2 of PC board space and can handle power from 400W to 3000W during pulses and instantaneous electrostatic discharges occurring in vehicle wiring.
Key Features of ST’s Automotive Transil Protection Devices:
• ISO 7637 standard instantaneous inflow voltage test and certification completed
• Tested and certified for ISO10605 standard electrostatic discharge
• AEC-Q101 certified
• Provides unidirectional and bidirectional solutions
• SM4TY: SMA package, 2.55 x 5.05mm, 400W
• SMA6TY: SMA package, 2.55 x 5.05mm, 600W
• SM6TY: SMB package, 3.60 x 5.35mm, 600W
• SM15TY: SMC package, 5.90 x 7.95mm, 1500W
• SM30TY: SMC package, 5.90 x 7.95mm, 3000W
ST Automotive (AGAC) Transil protection devices are currently in mass production in SMA, SMB, or SMC packages, priced from $0.118 to $0.528 for unidirectional devices and $0.129 to $0.558 for bidirectional devices. Separate pricing conditions are available for bulk orders.
