_______________________________________________________________________________________ UNITED MICRO DEVICE INC. UMD05-0402 _______________________________________________________________________________________ PKCSP0402 Single Line TVS Diode for ESD Protection Description TVS diodes are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. The UMD05-0402 is a Uni-Directional TVS that is designed to provide high overvoltage protection by clamping action and have instantaneous response to transient overvoltages. The PKCSP0402 is a very small package which allows space saving on high density printed circuit board and also gives the designer the flexibility to protect one line in applications where arrays are not practical. Small Surface Mount Device TVS PKCSP0402 Pin Configuration 1 2 Pin Description 1 Cathode 2 Anode Features * Solid-state silicon avalanche technology * PKCSP0402 package * Uni-Directional protection * Protects one I/O or Power line * 150 Watts peak pulse power (tp = 8/20µs) * Working voltage: 5V * Low clamping factor Vcl/Vbr * Low leakage current * Full RoHS compliance * Complies with the following standards: - IEC 61000-4-2 (ESD) Air-15kv, Contact-8kv - IEC 61000-4-4 (EFT) (5/50ns) - IEC 61000-4-5 (Surge) (8/20µs) Mechanical Characteristics * Molded PKCSP0402 ...
