Minimal space constraints and excellent device protection features

STMicroelectronics has launched a new ultra-small (0201 size) single-line ESD protection diode. It can rapidly lower instantaneous voltage to 7V and handle peak pulse currents of 7A, providing excellent protection and design flexibility for space-constrained devices. Additionally, it can drop to the lowest clamping voltage available at application-level capacitance and standoff voltages.



The unidirectional ESDZL5-1F4 and bidirectional ESDZV5-1BF4 feature snap-back characteristics with a trigger voltage of 5.8V and low dynamic resistance, providing excellent protection for devices measuring only 0.58mm x 0.28mm (standard size). They also ensure the integrity of high-speed signals with a minimum capacitance of 6pF. It can withstand contact and discharge of 15kV and 18kV, both exceeding the IEC 61000-4-2 specifications.

ST's new ESD clamping diodes can maximize battery life with a leakage current of less than 100nA, making them ideal for protecting equipment such as industrial sensors, IoT devices, active cables, connectors, smart-home appliances, wearable devices like smartwatches and healthcare/fitness bands, and portable products like smartphones, tablets, data loggers, and Point-of-Sale (POS) terminals.

As a pioneering developer of O2O1 packaging technology for mass-produced components, ST was able to leverage this expertise to supply this ultra-compact, space-saving solution. Furthermore, consistent quality is guaranteed through proven component manufacturing process technology, and stable supply for mass production orders is possible based on mass production capabilities.

Unidirectional ESDZL5-1F4 and bidirectional ESDZV5-1BF4 are currently in mass production, and samples are available.
