STMicroelectronics' miniature (0201-size) single-line ESD-protection diodes quickly clamp transients to a voltage as low as 7 V and handle 7 A peak pulse current to provide superior protection and design flexibility for space-constrained smart objects. These diodes drop the bar with the lowest clamping voltages available at this level of capacitances and stand-off voltages.

The unidirectional ESDZL5-1F4 and bidirectional ESDZV5-1BF4 have a snap-back characteristic, with 5.8 V trigger voltage and low dynamic resistance, to provide outstanding protection in a device measuring only 0.58 mm x 0.28 mm (typical). Also, with as little as 6 pF capacitance, they ensure the integrity of high-speed signals. Capable of withstanding 15 kV and 18 kV contact discharge, respectively, both devices exceed the IEC 61000-4-2 specifications. 

With leakage current below 100 nA helping to maximize battery life, ST’s ESD-clamping diodes are ideal for protecting equipment, such as industrial sensors, IoT devices, active cables and connectors, smart home electronics, wearable devices like smart watches and healthcare or fitness bands, and portable products including smartphones, tablets, data loggers, and point-of-sale terminals.
