Introduction

TPSMB asymmetric transient voltage suppressor (TVS) diodes protect automotive silicon carbide (SiC) MOSFET gate drivers (TPSMBxx05CA) from overvoltage events and provide reverse battery protection for 12V systems (TPSMBxx12, TPSMBxx16, and TPSMBxx18). These devices feature asymmetric reverse standoff voltages, enabling simultaneous protection against both positive and negative transients with different clamping characteristics in a single component — making them an ideal solution for robust protection in automotive electronic systems.

Features

• Single SMB package device providing asymmetric clamping for positive and negative transient voltages
• High-reliability applications, compliant with automotive-grade AEC-Q101
• 600W Pₚₚₘ peak pulse power capability under 10/1000μs waveform at 0.01% repetition rate (duty cycle)
• SMT component for optimized board space
• Low-profile package
• Typical failure mode: short circuit due to overvoltage or overcurrent
• Whisker tested per Table 4a and 4c of JEDEC JESD201A
• ESD protection on data lines: 30kV (air), 30kV (contact) per IEC 61000-4-2
• EFT protection on data lines per IEC 61000-4-4
• Glass-passivated chip junction
• Fast response time: typically less than 1.0ns from 0V to V₍₍BR₎₎min
• Excellent clamping capability
• Low incremental surge resistance
• UL-recognized compound, V-0 flammability rating
• MSL Level 1 per J-STD-020, guaranteed high-temperature soldering: terminals at 260ºC for 10 seconds
• Matte tin lead-free plating
• Halogen-free and RoHS compliant
• Lead-free E3 denotes second-level interconnect lead-free with tin (Sn) terminal finish (IPC/JEDEC J-STD-609A.01)
