TVS (Transient Voltage Suppressor)- Diodes are used to protect electronic circuits against any transient overvoltage events such as ESD (Electrostatic Discharge), lightning, surges, and electro-magnetic pulses. BZW04-94HB0G is a TVS-Diode, developed by TAI-Semiconductor, which combines high Surge capability with excellent ESD performance.

BZW04-94HB0G is an excellent choice for protecting I/O Circuits, Power and Signal Lines against ESD, Lightning and Surge Events. Its highly reliable design includes an excellent operating voltage of 14V to +76V and surge current capability of 10A for 8/20μs. Additionally, this TVS-Diode has a low capacitance of 0.07pF and a fast response time of 10ns.

BZW04-94HB0G application field includes Automotive Electronics, Industrial Control, IT & Telecom, Medical Equipment, Military & Aerospace and Consumer Electronics. The main purpose of applying this TVS-Diode is to protect sensitive electronic components from high voltage over current events such as Electrostatic Discharge (ESD), lightning and surges.

The working principle of BZW04-94HB0G is simple, it consists of a silicon controlled rectifier, a Zener diode and an N-channel enhancement MOSFET. These components interact to enable the TVS-Diode to clamp overvoltage in the circuit by turning the MOSFET ON and OFF. The MOSFET is normally kept off, but when the voltage in the circuit rises above the breakdown voltage of the Zener Diode, the MOSFET is turned on to clamp the voltage. When the voltage returns to normal, the MOSFET is turned off once again.

BZW04-94HB0G has a Pb-free, RoHS compliant package, and can operate up to a temperature range of -55°C to +125 °C. This TVS-Diode can withstand 15KV ESD pulses, and can also withstand 10A surge current with 8/20 µs pulse width. Additionally, it has an excellent response Time of 10ns and can be easily applied in Automotive, Consumer and Industrial Electronics.

In short, BZW04-94HB0G is an excellent choice for protecting I/O Circuits, Power and Signal Lines from ESD, Lightning and Surge Events. Its excellent operating voltage, Surge current capabilities and fast response time make this TVS-Diode the perfect choice for Automotive, Industrial, Consumer and other Electronics.
