The BZX84C4V3LT1 is a 4.3V Zener diode from On Semiconductor designed for voltage regulation in space-constrained applications. It offers a nominal zener voltage of 4.3V with a tolerance of ±7% and a maximum power dissipation of 225mW at 25°C ambient temperature on FR-5 board. The device features a maximum impedance of 90Ω and a reverse leakage current of 3µA at 1V reverse voltage.
This Zener diode is housed in a surface mount SOT-23-3 package (also known as TO-236-3 or SC-59), making it suitable for automated assembly and high-density PCB designs. The operating temperature range spans -65°C to 150°C, with a junction temperature maximum of 150°C. Thermal resistance is 556°C/W on FR-5 board and 417°C/W on alumina substrate.
Typical applications include voltage regulation in portable electronics, cellular phones, and handheld devices where board space is at a premium. The device is also ESD rated at >16kV (Human Body Model, Class 3), providing robust protection in handling and operation.
