TVS - Diodes

TVS-diodes (TVS or transient voltage suppressors) are semiconductor protection devices designed to protect electronic circuits from transient unwanted voltage changes- either positive or negative. This type of device clamps and limits the transient voltages within predefined safe values, thus providing both an electrical and a thermal protection to the sensitive circuits. They minimize the risks of electrostatic discharge (ESD) and electromagnetic interference (EMI), and provide protection against transients from switching of inductive loads.The SPHV36-01KTG-C is an example of a transient voltage suppressor suitable for a wide range of applications where voltage clamps, spikes, overvoltages, and surges must be suppressed. This is a 36V unidirectional device packaged in DO-214AA SMC (Surface Mount Chip) package.

Application field

The SPHV36-01KTG-C is suitable for a wide range of applications including automotive, cell phones, GPS modules, computers and networks, satellite equipment, medical instruments, and other systems that are sensitive to transients. Its wide operating temperature range, small form factor, and superb surge capability make it perfect for many automotive applications. It can be used to protect the circuits from voltage overshoots in such locations as automotive ECUs, ABS brakes, systems with secondary ignition, LED lighting, and airbag deployment systems.In addition, the SPHV36-01KTG-C is ideal for networking and communications applications, cell phones, and portable equipment. It can also be used to protect internal circuitry and other sensitive components from damage caused by electrostatic discharge (ESD).

Working principle

Transient voltage suppressors are bidirectional devices, meaning they can handle both positive and negative transient voltages. The SPHV36-01KTG-C consists of two zener diodes with one each reverse-biased and connected in parallel to the device.When the input transient voltage exceeds one of the device\'s thresholds, the diode that is biased in the reverse direction will switch on and clamp the voltage transient. As a result, the transient is limited to the device\'s pre-defined breakdown voltage. This process is repeated for both positive and negative transients, thus providing electrical and thermal protection to the device.In addition, the SPHV36-01KTG-C also incorporates an internal thermistor that provides additional protection against overvoltage transients and spikes. This gives the device superior surge capability and enables it to clamp voltage transients as quickly and reliably as possible.

Conclusion

The SPHV36-01KTG-C is a transient voltage suppressor designed to protect electronic circuits from transient overvoltages and surges. Its superior surge capability, small form factor, and wide operating temperature range make it suitable for a wide range of applications, including automotive, cell phones, GPS modules, computers and networks, satellite equipment, medical instruments, and more. Its working principle involves two zener diodes connected in parallel which clamp the voltage transient when it exceeds the device\'s threshold.
