BZX84C33 Description

Short technical summary and product information.

The BZX84C33 is a 33V Zener diode designed for low-power voltage regulation and protection circuits. With a nominal zener voltage of 33V and ±5% tolerance, it provides a stable 33V reference. The diode offers a zener impedance of 80 Ω at 5 mA and 55 Ω at 20 mA, ensuring good regulation under varying currents. Power dissipation is rated at 250 mW when mounted on an FR-4 PCB, with a junction-to-ambient thermal resistance of 465 °C/W. The device operates over a temperature range of -55°C to +150°C, making it suitable for industrial and automotive environments. The forward voltage is 900 mV at 10 mA. Packaged in a surface-mount SOT-23-3, the BZX84C33 is ideal for space-constrained designs. The part is RoHS and REACH compliant with an MSL rating of 1 (unlimited).
