The CZRER52C18 is a surface-mount Zener diode from Comchip Technology's CZRER52C series, designed for voltage regulation applications. With a nominal Zener voltage of 18V at 5mA test current, it provides a stable reference voltage with ±5% tolerance. This diode can dissipate up to 150mW at 25°C ambient temperature, making it suitable for low-power circuits.
Key electrical specifications include a maximum forward voltage of 900mV at 10mA, a reverse leakage current of 100nA maximum at 14V reverse voltage, and dynamic impedance values of 50Ω (at 5mA, Zzt) and 170Ω (at 1mA, Zzk). The device can handle a forward surge current of 2A for 8.3ms single half sine-wave. Additionally, it offers ESD protection up to 8kV per IEC 61000-4-2.
The CZRER52C18 is housed in a 0503 (1308 Metric) package, also known as SOD-723F, with gold-plated terminals that are solderable per MIL-STD-750. It features a cathode band for polarity identification and weighs approximately 0.002 grams. The operating junction temperature range is -55°C to 125°C. The device is RoHS compliant, halogen free, and lead free.
