TCN4040 Datasheet – Shunt Voltage Reference

The TCN4040 is a PRECISION MICROPOWER SHUNT VOLTAGE REFERENCE made by TelCom Semiconductor, supplied in these packages: SOT-23B-3, TO-92, and SO-8 Type. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the TCN4040 pinout and maximum ratings, with the full datasheet PDF to preview below or download.

For applications in tight quarters, the TCN4040 precision voltage reference is available in a space-saving 3mm x 1.3mm SOT-23B-3 surface mount package. The TCN4040 eliminates the need for an external stabilizing capacitor while maintaining stability with any capacitive load. The minimum operating current is 60mA. The maxi- mum operating current is 15mA.

To ensure that the prime parts have an accuracy of better than ±0.5% (C grade) at 25°C, the TCN4040 uses fuse and zener-zap reverse breakdown voltage trim during wafer sort. Low dynamic impedance and bandgap reference temperature drift curvature correction maintain stable re- verse breakdown voltage accuracy over a wide range of operating temperatures (– 40°C to + 85°C) and currents from (60mA to 15mA).

The TCN4040 also is available in both adjustable and 1.2V versions.
