BCD Semiconductor Manufacturing Limited AZ431
The AZ431 series ICs are three-terminal adjustable shunt regulators with guaranteed thermal stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger and other adjustable regulators. The AZ431 series ICs contain two voltage types, AZ431-A for 40V and AZ431-B for 20V.| Part No. | AZ431 |
