In today’s rapidly evolving Internet of Things (IoT) technology landscape, smart edge devices are increasingly becoming the bridge between the physical and digital worlds. From smart homes to wearable devices, from smart cities to industrial automation, the applications of smart edge devices are expanding, and higher demands are being placed on their security, reliability, and stability. Among these devices, circuit protection plays a crucial role, and the importance of Transient Voltage Suppressors (TVS), which are key components in circuit protection, cannot be overstated. Today, we focus on introducing the SMF12A, an outstanding transient voltage suppressor designed specifically for smart edge devices.

SMF12A: A Leader in Unidirectional Protection

The SMF12A is a unidirectional transient voltage suppressor that boasts excellent electrical characteristics and protection performance. Its Reverse Working Voltage (Vrwm) is 12V, meaning that under normal operating voltage, the SMF12A conducts almost no current, posing no impact on the circuit. However, when the circuit faces a transient overvoltage spike, the SMF12A responds rapidly, clamping the overvoltage to a safe level and protecting the circuit from damage.

Breakdown Voltage and Reverse Leakage Current: Precisely Controlled Protection

The SMF12A’s breakdown voltage ranges from 13.3V to 14.7V, a precise range that ensures the device activates its protective mechanism at the appropriate voltage—neither too early to cause unnecessary energy loss nor too late to risk the circuit’s safety. Additionally, its reverse leakage current is a minimal 2.5μA, which can essentially be ignored in normal operating conditions, further reducing the circuit’s energy consumption.

Peak Pulse Current and Clamping Voltage: Powerful Transient Overvoltage Suppression

When exposed to transient overvoltage spikes, the SMF12A can withstand peak pulse currents of up to 10.1mA (Ipp) @10/1000μs. This capability ensures it can handle most common transient overvoltage events with ease. Its maximum clamping voltage is 19.9V, well below the maximum voltage that many smart edge devices can tolerate, ensuring that even in extreme transient overvoltage conditions, the circuit is adequately protected.

Peak Pulse Power: Power to Handle Extreme Challenges

The SMF12A has a peak pulse power (Ppp) rating of 200W @10/1000μs, demonstrating its powerful transient energy absorption capacity. In the event of an extreme transient overvoltage, the SMF12A quickly converts the overvoltage energy into heat and dissipates it, preventing circuit damage due to overheating. This characteristic makes the SMF12A especially suitable for smart edge devices that must endure high-energy transient overvoltage events.

A Perfect Match with Ceva-Waves Links200

In the development of smart edge devices, circuit protection is often closely tied to wireless connectivity technologies. As a global leader in semiconductor products and software IP licensing, Ceva's Ceva-Waves Links200 turnkey multi-protocol platform IP product stands out as a top-tier wireless connectivity solution for smart edge devices. The Links200 integrates next-generation Bluetooth High Data Throughput (HDT) technology as well as IEEE 802.15.4 standards for Zigbee, Thread, and Matter, providing efficient and reliable wireless connectivity for smart edge devices.

However, no matter how advanced wireless connectivity technology is, it requires the support of circuit protection. The SMF12A, as an ideal circuit protection component, perfectly complements the Links200. While the Links200 delivers robust wireless connectivity capabilities to smart edge devices, the SMF12A silently safeguards the circuit, ensuring that devices can operate stably in a variety of complex environments.

Conclusion

As smart edge devices become increasingly prevalent, the importance of circuit protection is undeniable. The SMF12A, with its precise breakdown voltage control, powerful transient overvoltage suppression capability, and high energy absorption capacity, has become a preferred component for circuit protection. Its integration with advanced wireless connectivity technologies like Ceva-Waves Links200 further enhances the protection and support for smart edge devices. In the future IoT world, the SMF12A will continue to play a vital role in ensuring the safe and stable operation of smart edge devices.
