BZX79-C18,133 Description

Short technical summary and product information.

The BZX79-C18,133 is a voltage regulator diode from the BZX79 series by Nexperia. It provides a nominal Zener voltage of 18V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 400mW at an ambient temperature of 50°C (500mW at tie-point ≤50°C with max lead length 8mm). It features a maximum impedance (Zzt) of 45Ω and a typical forward voltage of 900mV at 10mA. The reverse current is limited to 50nA at 12.6V. This diode is suitable for low-voltage stabilizers and voltage reference applications. It is housed in a hermetically sealed DO-204AH (DO-35) glass package with axial leads, designed for through-hole mounting. The operating temperature range spans from -65°C to 200°C, matching the storage and junction temperature ranges. The device is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified.
