TVS (Transient Voltage Suppressors)
TVS has fast response speed to against overvoltage spikes. It has low dynamic internal resistance and excellent
clamping capability. Yageo offers different packages in TVS products and the working voltage of TVS diodes
are from 3.3 to 600V(and can be even higher). TVS diodes are used in unidirectional or bidirectional of data
transmission lines in electronic circuits.
Applications
• DC power supply • Security surveillance • Telecom • Automotive

ESD (Electrostatic Discharge Protection Devices)
ESD is also known as TVS array. It has excellent clamping capability and low capacitance (under 1pF) which can
meet the quality requirement of application in high speed data interface. Yageo provides high design flexibility
for capacitance, configuration, and pulse load capability in ESD solutions for the usage in different applications.
Applications
• High speed networking • Smart phone • Industrial • Consumer

MOV (Metal Oxide Varistors)
MOV has fast response speed to against overvoltage spikes and good surge energy absorption capability. It is
usually used in lightning surge protection in the input of AC power lines.
Applications
• AC power supply • Telecom • Circuit breaker • Consumer • SPD (Surge Protection Devices)
• LED driver • Smart meter

GDT (Gas Discharge Tubes)
GDT is a good solution for surge protection. The insulation resistance of GDT is over 1GΩ, which achieves low
degradation speed and high reliability. Yageo offers different packages including SMD and DIP type GDT. GDT
with two-electrode, three- electrode are both available.
Applications
• Telecom • High speed networking (e.g. coaxial cable, Ethernet connection) • Industrial • Power Supply

SPG (SPark Gap Protectors)
SPG has low junction capacitance (< 2pF) which can meet the quality requirement of application in
telecommunication. SPG has faster response speed (GDT ≤ 100nS, SPG ≤ 1nS) than GDT. Yageo offers SPG
products in both SMD and DIP type package for different application requirements.
Applications
• Power supply • Telecom • Safety surveillance • Industrial

PPTC (Polymeric Positive Temperature Coefficient Thermistor)
PPTC is also known as resettable fuse. It has very low resistance under normal working status, no impact on
the working circuit. The response speed of PPTC is from few dozen ms to few seconds level. It is proportional
to the current value. Yageo provides SMD (case size: 0603 ~ 2920) and DIP package types for the usage in
different applications.
Applications
• Industrial • Smart meter • Measuring instrument • Telecom

TSS (Thyristor Surge Suppressors)
TSS has fast response speed and excellent clamping capability to against overvoltage spikes. Low leak current
(in mA~100μA level) and junction capacitance (in 10~100pF level) features can meet the quality requirement in
data transmission and low power consumption circuits. Yageo offers various packages in SMD and DIP types for
different application requirements.
Applications
• Telecom
• Industrial
• Smart meter
• Security surveillance
