Zener Voltage Regulators

Transcription

1 Zener Voltage Regulators 200 mw SOD-323 Surface Mount This series of Zener diodes is packaged in a SOD 323 surface mount package that has a power dissipation of 200 mw. They are designed to provide voltage regulation protection and are especially attractive in situations where space is at a premium. They are well suited for applications such as cellular phones, hand held portables, and high density PC boards. Specification Features: High demand voltage range (3.6V-36V) Steady State Power Rating of 200 mw Small Body Outline Dimensions: 0.067" x 0.049"(1.7 mm x 1.25 mm). Low Body Height: 0.035" (0.9 mm) Package Weight: mg/unit ESD Rating of Class 3 per Human Body Model Pb-Free package is available. S- Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable. We declare that the material of product compliance with RoHS requirements. Mechanical Characteristics: CASE: Void-free, transfer-molded plastic FINISH: All external surfaces are corrosion resistant MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260 for 10 Seconds POLARITY: Cathode indicated by polarity band FLAMMABILITY RATING: UL94 V-0 MOUNTING POSITION: Any LUDZS2.4BT1G Series S-LUDZS2.4BT1G Series 1 MARKING DIAGRAM xx xx=device Marking Code M =Date Code 1 CATHODE SOD 323 M 2 2 ANODE ORDERING INFORMATION Device Package Shipping LUDZS2.4BT1G Series SOD /Tape&Reel LUDZS2.4BT3G Series SOD /Tape&Reel *See specific marking table.
