The DDZ20ASF-7 is a surface-mount precision Zener diode from Diodes Incorporated. It provides a nominal Zener voltage of 18.51V with a tolerance of ±2.46%. The device is rated for a maximum power dissipation of 500mW on standard FR-4 PCB, making it suitable for voltage regulation and clamping applications in low-power circuits.
The part features a maximum Zener impedance of 50Ω at 1kHz, forward voltage of 900mV at 10mA, and a maximum reverse leakage current of 70nA at 17.1V. It is housed in the tiny SOD323F package (SC-90 case style), which is ideal for space-constrained designs. The operating junction temperature range is -65°C to 150°C, and the thermal resistance from junction to ambient is 250°C/W.
This Zener diode is supplied on tape and reel in quantities of 3000 pieces. It is fully RoHS3 compliant, lead-free, and halogen and antimony free with a green molding compound. The terminals have a matte tin finish and are solderable per MIL-STD-202, Method 208.
