The DDZ18CSF-7 is a precision Zener diode from Diodes Incorporated, offering a nominal Zener voltage of 17.88V with a tight ±3% tolerance. It is designed for 500mW power dissipation on standard FR-4 printed circuit boards, making it suitable for voltage regulation and protection applications in compact electronics.
Key electrical characteristics include a maximum Zener impedance of 45Ω at 1kHz, a forward voltage of 0.9V at 10mA, and a reverse leakage current of 70nA at 16.5V. The device operates over a wide temperature range from -65°C to 150°C, with a junction-to-ambient thermal resistance of 250°C/W.
The diode is housed in a surface mount SOD-323F package (also known as SC-90), which is designed for automated assembly processes. It is supplied in tape and reel packaging with 3000 units per reel. The component is fully RoHS3 compliant, lead-free, halogen-free, and has an MSL rating of Level 1 (unlimited).
The nominal Zener voltage is 17.88V with a tolerance of ±3%.
The forward voltage is typically 0.9V at 10mA forward current.
The device is available in surface mount SOD-323F (SC-90) package.
The maximum power dissipation is 500mW.
The maximum reverse leakage current is 70nA at 16.5V reverse voltage.
The operating temperature range is -65°C to 150°C.
The maximum Zener impedance is 45Ω at 1kHz.
