Transient Voltage Suppressors (TVS) Diodes

Features of our low-capacitance TVS diodes include:

• Reliable protection against transient voltage events in demanding environments
• An excellent fit for high-speed signal lines where minimal signal distortion is critical
• Robust construction
• Undergo rigorous testing and screening to meet stringent quality and reliability standards
• Protect sensitive electronic circuits in harsh operating conditions
• Long-term reliability and performance in aerospace, defense and other mission-critical applications where environmental factors such as humidity, temperature and pressure fluctuations can pose challenges

Our low-profile, surface-mount 400W SMASF series Transient Voltage Suppressor (TVS) diodes are available in a flat-lead plastic package with standoff voltages from 5.8V to 214V and in unidirectional or bidirectional versions. Options include Sn/Pb or RoHS-compliant matte-tin plating. These high-reliability devices feature wafer fabrication and assembly lot traceability and undergo 100% surge testing with enhanced reliability screening similar to MIL-PRF-19500 standards. The moisture classification is Level 1, which eliminates the need for dry packing required by the IPC/JEDEC J-STD-020B standard. Additionally, 3σ lot-norm screening is performed on standby current (I_D).

Our surface-mount PLAD TVS diodes play a crucial role in enabling avionics systems to comply with the latest safety standards mandated for modern carbon composite-skinned aircraft. By enhancing surge protection, our PLAD packaging effectively mitigates the risks of digital signal processing disruption, component damage and functional interruptions that are the indirect effects of lightning.

Our PLAD TVS diodes represent a breakthrough in surface-mount TVS packaging for 15 kW, 18 kW, 30 kW and 36 kW devices.
