TVS Diodes Protect Booming ‘Tiny Smart Objects’

ST has launched new miniature (0201 size) single-line TVS diodes designed to protect the data line or other I/O ports against ESD transients. Claiming a leakage current below 100nA to maximize battery life, ST’s new 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.

ST claims that the new diodes quickly clamp transients to a voltage as low as 7V, and handle 7A peak pulse current, to provide superior protection and space-saving for space-constrained smart objects.

“This diode drops the bar with the lowest clamping voltage available at this level of capacitance and stand-off voltage”, according to ST.

The unidirectional ESDZL5-1F4 and bidirectional ESDZV5-1BF4 have a snap-back characteristic, with 5.8V trigger voltage and low dynamic resistance, to provide outstanding protection in a device measuring only 0.58mm x 0.28mm (typical).

The devices also feature a very little capacitance of 6pF to ensure the integrity of high-speed signals. Capable of withstanding 15kV and 18kV contact discharge respectively, both devices exceed the IEC 61000-4-2 specifications.

The unidirectional ESDZL5-1F4 and bidirectional ESDZV5-1BF4 are in production now, and samples are available. Pricing is from $0.014 for orders of 5000 units.
