DDZ8V2B-7 Description

Short technical summary and product information.

The DDZ8V2B-7 is a surface mount precision Zener diode from Diodes Incorporated. It offers a nominal zener voltage of 8.2V with a very tight tolerance of ±2.5%, making it suitable for voltage regulation and reference applications. The device has a maximum power dissipation of 470mW at 25°C ambient temperature (Note 7) and a forward voltage of 900mV typical at 10mA forward current. Zener impedance is 8Ω maximum, and reverse leakage current is 100nA maximum at 6.5V reverse voltage.

The operating temperature range spans -65°C to 150°C, allowing use in harsh environments. The diode is housed in a SOD-123 surface mount package with matte tin annealed terminals, solderable per MIL-STD-202, Method 208. It is supplied in tape and reel packaging with 3000 units per reel, ideal for automated assembly.

Compliance includes RoHS3, lead-free, and halogen-free (bromine <900ppm, chlorine <900ppm, antimony <1000ppm). Moisture sensitivity level is 1 (unlimited) per J-STD-020. The DDZ8V2B-7 is designed for applications requiring precise voltage clamping, overvoltage protection, and general purpose voltage regulation.
