The STMicroelectronics ESDA6V1L is a TRANSIL™ TVS diode (Zener type) rated for 300W peak pulse power (8/20 µs waveform typically), with a reverse standoff voltage of 5.25V and a minimum breakdown voltage of 6.1V. It packs two unidirectional channels into a single SOT-23-3 package, making it a space-efficient choice for clamping transients on two signal or supply lines in general-purpose equipment.
Two channels, one footprint — BOM consolidation
With two unidirectional channels in a single SOT-23-3, this part replaces two discrete TVS diodes while saving board area and reducing pick-and-place cost. The 5.25V standoff suits 3.3V and 5V logic rails where the normal operating voltage stays below that threshold; the 6.1V minimum breakdown ensures the device stays off during normal bias.
