TVS Diodes

Bourns Surface-Mount TVS Diodes are low capacitance devices that provide ESD, EFT, and surge protection for external ports of electronic devices such as cell phones, handheld electronics, and other portable electronic devices. Bourns TVS Diodes include smaller chip diodes that have the capability to provide a silicon diode with minimal packaging overhead. The chip diodes 0603, 1005, 1408, and 2010 are leadless, allowing for maximum space on PCB layouts. All Bourns diodes are RoHS compliant and meet many worldwide industry and government regulations on lead-free components. TVS package diode design kits are also available from Bourns.

CD143A-SR05LC 2-line 5V TVS/Steering Diode Array

Bourns CD143A-SR05LC 2-line 5V TVS/Steering Diode Array includes the low capacitance of 3pF and provides ESD, EFT, and surge protection for the external ports of portable electronic devices such as cell phones, handheld electronics, and personal computers. The ESD protection provided by the component enables a data port to withstand a minimum ±8KV Contact / ±15KV Air Discharge per the ESD test method specified in IEC 61000-4-2 and protects Vcc and two data lines.

Gas Discharge Tube for RS-485 Ports

Bourns Gas Discharge Tube (GDT) for RS-485 Ports is designed to meet industry standards on RS-485 port interfaces and to provide circuit protection in noisy and harsh electrical environments. For exposed lines that may see large and fast surges and where failure is not acceptable, a three-stage Bourns protection system is recommended.

Circuit Protection Devices

Bourns manufactures and supplies a wide range of circuit protection technologies, including fuses, PTC thermistors, varistors, GDTs, resettable thermal cut-offs, surge protection devices, hybrid protectors, discrete semiconductor solutions, and more. Reliable surge protection is a critical design consideration to help ensure operational reliability of consumer electronics, industrial/communication equipment, automotive, battery charging, energy storage infrastructure, and renewable energy harvesting ecosystems.
