BZG03C18TR Description

Short technical summary and product information.

The BZG03C18TR is a single Zener diode from Vishay Dale belonging to the BZG03C series. It features a nominal zener voltage of 18V with a tolerance of ±6% (minimum 16.8V, maximum 19.1V). The power dissipation is rated at 1.25W at 50°C ambient when mounted with a thermal resistance below 100 K/W, and up to 3W at 100°C ambient with a thermal resistance below 25 K/W. The device can handle non-repetitive peak surge power up to 600W (100 µs pulse).

This diode offers excellent dynamic characteristics including a typical zener impedance of 6 ohms and a reverse leakage current of only 1 µA at 13V. It is designed for voltage stabilization applications. The junction temperature rating is 150°C with a storage temperature range of -65°C to +150°C.

The device is housed in a DO-214AC (SMA) surface mount package weighing approximately 77 mg. It is supplied in tape & reel format (1500 pieces per 7" reel) and is lead (Pb)-free and RoHS-compliant. The component is suitable for wave and reflow soldering processes.
