STMicroelectronics ESDZL5-1F4 and ESDZV5-1BF4 ESD-clamping diodes

Thursday, 20 July, 2017 | Supplied by: STMicroelectronics Pty Ltd


The latest miniature (size 0201) single-line ESD-protection diodes from STMicroelectronics quickly clamp transients to a voltage as low as 7 V, and handle 7 A peak pulse current, to provide good protection and design flexibility for space-constrained smart objects. The diodes are claimed to have the lowest clamping voltage available at this level of capacitance and stand-off voltage.

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 high protection in a device measuring only 0.58 x 0.28 mm (typical). With as little as 6 pF capacitance, they ensure the integrity of high-speed signals. Capable of withstanding 15 and 18 kV contact discharge respectively, both devices exceed the IEC 61000-4-2 specifications.

With leakage current below 100 nA helping to maximise battery life, the ESD-clamping diodes are suitable 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.
