DISCRETE SEMICONDUCTORS DATA SHEET book, halfpage M3D049 BZX399 series Voltage regulator diodes 1999 Jun 04 Product specification Philips Semiconductors Product specification Voltage regulator diodes BZX399 series FEATURES PINNING • Total power dissipation: max. 300 mW PIN DESCRIPTION • Tolerance: ±5% 1 cathode • Working voltage range: nom. 1.8 to 43 V (E24 range) 2 anode • Improved IZ/VZ characteristic at low currents (IZ =50µA). This results in a noise free and sharp breakdown knee. APPLICATIONS handbook, halfpage 12 • General regulation functions, where low noise at low currents is required , • Low power consumption applications Top view MAM387 (e.g. hand-held applications). DESCRIPTION Fig.1 Simplified outline (SOD323) and symbol. Low-power low noise v
