Transient Voltage Suppression (TVS) Diode devices are solid-state components typically used to protect a circuit from induction of surge or transient voltage. Generally, they are made up of so-called “avalanche”-like diode structures, and the industry recognizes numerous types of devices, including Zener, VDR, Schottky, PESD, etc.

The PESD3V3C1BSFYL is one such TVS diode which provides an ideal choice for surge protection in industrial and telecommunication applications, such as data lines, power supplies, signal lines, and other high-speed signal systems.

The PESD3V3C1BSFYL diode offers a sophisticated yet simple approach for protecting circuits against repetitive ESD (electro-static discharge) or high current transients. It is capable of handling high voltage spikes while clamping them at a safe level with very low dynamic resistance.

The PESD3V3C1BSFYL includes an array of interleavedSchottky diodes for enhanced ESD protection, as well as high transient surge protection. This device is rated 45 volts and has a powerful 350 watts peak pulse power capability. It also has a low operating voltage of 3.6 volts, and an operating temperature range of -65°C to +175°C.

The working principle of the PESD3V3C1BSFYL is based on avalanche breakdown, which is a process whereby the voltage across an individual diode exceeds its breakdown voltage, allowing an entire blocking region to become forward biased and permitting current to flow. This breakdown is caused by a high electric field, which causes a large number of electron holes to combine, creating so-called “avalanche breakdown”.

In the PESD3V3C1BSFYL, this avalanche breakdown process leads to the device rapidly switching from its blocking to its “on” state. This ensures that the surge voltage is clamped at a safe level, thereby protecting the circuits from such voltage spikes. The device then reverts back to its “off” state, allowing the circuit to return to normal operation.

In conclusion, the PESD3V3C1BSFYL is a powerful TVS diode designed for optimum surge protection. In addition to its excellent electrical properties, it is also able to withstand a wide operating temperature range, making it an ideal choice for applications requiring effective protection from voltage spikes and ESD events.
