TVS - Diodes

Transient voltage suppression (TVS) diodes protect electronic circuits from damaging transients. These diodes can be used in a variety of applications and in different configurations to protect against varying levels of voltage and different types of threats. One such diode is the SMBG90CAHE3/52, which is a unique diode designed specifically for applications requiring high surge energy capability, transient protection, and ESD protection.

SMBG90CAHE3/52 Application Field and Working Principle

The SMBG90CAHE3/52 diode is primarily used in automotive, military/aerospace, and telecommunications/datacom applications. Its robust design provides low let-through voltage requirements during high-energy transients and ESD; up to a 35 Volt operating voltage; an avalanche capability of up to 6,000 Watts peak pulse power (10/1000μs) and a peak pulse current rating of 25 Amps. It is a unidirectional diode, meaning it helps protect against transient voltages only when the polarity of the voltage is oriented correctly. The working principle of the SMBG90CAHE3/52 diode is simple but effective. When the voltage across the diode is below its operating voltage, the diode remains nonconductive and does not allow current to pass through. When the voltage across the diode exceeds its operating voltage, the diode becomes forward-biased and allows a current to flow. This reduces the high-voltage shock and protects the electronic circuit from overvoltage. In addition, the reverse avalanche breakdown capabilities of the diode allow it to suppress large transients up to its breakdown voltage. The SMBG90CAHE3/52 is available in a molded plastic TO-252 DPAK package. The package includes a pair of leads which, when properly installed, will enable a high-speed switching and high performance with low peak let-through voltage. This makes it easy to incorporate into a variety of circuit designs.

Advantages of SMBG90CAHE3/52

The SMBG90CAHE3/52 provides many advantages over traditional diode protectors. It offers high surge energy capability, a low operating voltage, and an extended avalanche capability. Additionally it provides superior electromagnetic immunity for reliable protection against ESD events. The device\'s simplicity also makes it an ideal choice for applications requiring high performance and reliable protective circuits. It is small and lightweight and provides reliable performance over a wide temperature range. The molded plastic TO-252 DPAK packaging also makes it easy to incorporate into a variety of circuit designs.

Conclusion

The SMBG90CAHE3/52 is an innovative transient voltage suppression (TVS) diode that provides superior protection for electronic circuits against transient voltages and ESD events. Designed for use in automotive, military/aerospace, and telecommunications/datacom applications, it offers a high surge energy capability, low operating voltage, and extended avalanche capability in a small, lightweight package. With its simple design and reliable performance, it is an ideal choice for applications requiring high performance and reliable protective circuits.
