The 1.5SMC91CA TR13 is a Surface Mount Transient Voltage Suppressor (TVS) diode, designed to provide protection against voltage transients induced by lightning and other transient voltage events. Its small size offers board-level protection for sensitive components and systems.

Application Field

The 1.5SMC91CA TR13 is optimized for protecting sensitive electronic components against voltage transients caused by inductive switching, circuit faults, lightning, and electrostatic discharge. It is designed to prevent both over-voltage and under-voltage spikes from damaging delicate circuits. As such, it is ideal for protecting low-voltage board circuits, or for protecting interfaces relying on low-voltage signaling, such as data speeds. These devices can be used in both high- and low-voltage applications.

Working Principle

When voltage across the 1.5SMC91CA TR13 exceeds its peak pulse power rating, it triggers a protective current path. This path allows excess voltage to be quickly discharged, protecting sensitive electronic components. The 1.5SMC91CA TR13 has a low leakage current and is able to suppress oscillatory transients with very fast time-to-response rates. Its high pulse power capability allows it to be used to protect low voltage applications without the need for a separate Zener diode.

Once activated, the 1.5SMC91CA TR13 can be reset and reused without any additional components. This feature ensures that it is compatible with continuously powered circuit designs while still providing a reliable level of protection.

In its unactivated state, the 1.5SMC91CA TR13 does not affect the normal operation of the circuit, allowing it to be used in both digital and analog circuits without introducing any noticeable delays or power losses. This makes it a great choice for a wide variety of applications.
