AS431H Adjustable Shunt Regulators

Diodes Inc. AS431H Adjustable Shunt Regulators are three-terminal adjustable shunt regulators with guaranteed thermal stability over a full operating range. These adjustable precision shunt regulators feature sharp turn-on characteristics, low-temperature coefficient, and low output impedance. The AS431H regulators operate within -40°C to 125°C temperature range and are available in 0.5% and 1% voltage tolerance. These regulators are an ideal replacement for Zener diodes in various applications including switching power supply and other adjustable regulators. The AS431H shunt regulators are lead-free, RoHS compliant, and are available in T092 (ammo packaging) and S0T23 ("Green" molding compound).
