BZX84C33LT1

The BZX84C33LT1 is a Zener voltage regulator diode from On Semiconductor, offering a nominal breakdown voltage of 33V with a tolerance of ±6%. It is designed for voltage regulation in space-constrained applications such as cellular phones, handheld portables, and high-density PC boards. The device features a forward voltage of 900 mV at 10 mA, reverse leakage current of 50 nA at 23.1 V, and a maximum Zener impedance of 80 Ω. Power dissipation is rated at 225 mW on an FR-5 board at 25°C, with derating above 25°C. Thermal resistance is 556 °C/W on FR-5 and 417 °C/W on an alumina substrate. The diode is housed in a surface-mount SOT-23-3 package (TO-236) and supports an operating junction temperature range of -65°C to 150°C. It also carries an ESD rating of Class 3 (>16 kV) per the Human Body Model and a flammability rating of UL 94 V-0.
