zener and small-signal diode series

ON Semiconductor LLC (Phoenix, AZ) recently introduced zener and small-signal diode series in the SOD-323 package. According to ON Semiconductor, the SOD-323 package offers designers who use the same devices in SOT-23 and SOD-123 packages a transition to a smaller package outline. The company claims the smaller footprint of the SOD-323 package housing these new devices reduces the end-product size and increases portability. Several standard zener products previously available in SOT-23 and SOD-123 packages such as BZX84C, the MMBZ and the MMSZ Series are now available in the SOD-323. These zener diodes are designed to provide temperature-stable references for voltage regulation, for monitoring over- and under-voltage conditions, and for monitoring logic-level rails and battery levels. The devices cover a voltage range from 2.5V to 75V. According to ON Semiconductor, the SOD-323 offers a footprint outline of about 50mils by 80mils. It has a power dissipation rating of 200mW and is JEDEC registered. ON Semiconductor offers an expansive portfolio of technologies in the SOD-323, said Colette Hunt, vice president and general manager for the discrete products business at ON Semiconductor. This smaller package is ideally suited for portable products such as cellular phones, PDAs, pagers, cordless phones and TV/TR tuners where high density board design is a necessity. Samples and production quantities are currently available. In quantities of 3,000, pricing for the zener diodes is suggested at $0.04 and $0.12 for the small-signal devices.
