SMAJ28CA

Transient Voltage Suppressor SMAJ SERIES Description SMAJ Series transient voltage suppressors are excellent ervoltage protective devices. The Series is designed specifically to protect sensitive electronic quipment from voltage transients induced by lightning and other transient voltage events. SMA (DO-214AC) Features Mechanical Characteristics               Excellent clamping capability Low leakage current High surge capability Glass passivated chip Epoxy resin package Built-in strain relief Will not fatigue RoHS Compliant Fast response time: typically less than 1.0ps from 0 Volts to VBR min Package: SMA plastic package. Lead Finish: Matte Tin Case Material: Epoxy Molding Compound. UL Flammability Classification Rating 94V-0 Moisture Sensitivity: Level 1 per J-STD-020 Applications  Telecom  Computer  Industrial electronic  Consumer electronic Electrical Parameters Parameter +I Definition CJ Junction Capacitance - typical capacitance measured with 0V or VR bias IPP Peak Pulse Current - maximum rated peak impulse current VC Clamping Voltage - Peak voltage measured across the suppressor at a specified Ippm (peak impulse current) VBR Breakdown Voltage - Maximum voltage that flows though the TVS at a specified test current (IT) IR Leakage Current - maximum peak off-state current measured at VR VR Peak Off-state Voltage - maximum voltage that can be applied while maintaining off state www.pdwsemi.com 1 -7 VF Ipp Uni Bi IT IR VR VBR VC +V © 2022 PDW, Inc.
