ESD Protection Solutions

Littelfuse provides a wide range of products that protect components from ESD threats. ESD threats are extremely fast, low-energy events that can wreak havoc on electronic equipment. Trends in reduced chip protection and harsher end-user environments are requiring the need for enhanced protection solutions. Littelfuse produces varistors, suppressors, indicators, and more so users can find the right protection to ensure the long-term reliable operation of applications.

Transient Voltage Suppressor (TVS) Diodes

Littelfuse TVS (Transient Voltage Suppression) Diodes are a broad range of circuit protection products designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). Lightning strikes, inductive load switching, and ESD cause electrical over-stresses associated with the transmission on data lines and electronic circuits. Offered in a variety of surface mount and through-hole circuit board mounting formats, the TVS Diode portfolio includes high peak pulse current and peak pulse power options up to 20kA and 30kW, respectively. Littelfuse TVS Diodes are chosen for the fast response time (low clamping voltage), lower capacitance, and low leakage current. TVS Diodes are available in both unidirectional (unipolar) or bidirectional (bipolar) diodes circuit configurations. 

SRDA3.3 TVS Diode Array

Littelfuse SRDA3.3 TVS Diode Array is designed to protect telecommunications data lines against ESD and high surge events. This device can safely absorb up to 35A of lightning-induced surge current (tp=8/20μs) without performance degradation and can withstand a minimum of ±30kV ESD per the IEC61000-4-2 international standard. With just 8pF of capacitance (typical) from each I/O to ground, this Littelfuse device helps to maintain signal integrity, preventing data loss during transmission. Typical applications for this Littelfuse TVS diode array include tertiary (IC side) protection for telecommunication interfaces such as T1/E1/T3/E3 data lines, HDSL/SDSL, RS-232/RS-485 interfaces, 10/100/1000 Ethernet interfaces, and video lines. This device is also suitable for security cameras, storage DVRs, network equipment, instrumentation, medical equipment applications.

Lightning Surge TVS SPA Diodes

Littelfuse Lightning Surge TVS SPA Diodes are designed to limit the amount of unwanted voltages to prevent damage by blocking the surges. Applications for Littelfuse Lightning Surge TVS SPA Diodes include lightning I/O, 10/100/1000 Ethernet, and 2500/5000/10000 Ethernet.

TVS Silicon Protection Arrays (SPA)

Littelfuse Silicon Protection Array (SPA®) TVS Diodes are designed to protect electronics from very fast and damaging voltage transients, such as lightning and electrostatic discharge (ESD). These diodes offer an ideal protection solution for I/O interfaces and digital and analog signal lines in computer and consumer portable electronics. Littelfuse TVS diodes offer a broader application use and improved impulse protection performance over conventional diodes.
