PANJIT

<p>The PANJIT BZT52-C18S is a 200mW surface mount Zener diode from the BZT52-C2V4S series, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 18V with a tolerance of ±5%, ensuring a Zener voltage range of 17.10V to 18.90V at a test current of 5mA. The diode offers a maximum Zener impedance of 50Ω at IZT and 225Ω at IZK (1mA), and a reverse leakage current of 100nA maximum at 14V.</p><p>&nbsp;</p><p>This Zener diode is housed in a compact SOD-323 molded plastic package, suitable for automated assembly processes. It is rated for a power dissipation of 200mW when mounted on an FR-4 PCB with a 100cm² copper pad, and can operate over a junction temperature range of -55°C to +150°C. The device is lead-free and RoHS 3 compliant, with a cathode band for polarity identification.</p><p>&nbsp;</p><p>Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in low-power circuits. The small footprint and surface mount package make it ideal for space-constrained designs in consumer, industrial, and automotive electronics.</p>
