DESCRIPTION The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

1 DESCRIPTION The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. FEATURES For surface mounted applications in order to optimize board space. Low profile package. Built-in strain relief. Glass passivated junction. Excellent clamping capability. SMA/DO-214AC Repetition Rate (duty cycle):0.01%. Fast response time: typically less than 1.0ps from 0 Volts to VBR for unidirectional types. Typical IR less than 1μA above 10V. High Temperature soldering: 260 C/10 seconds at terminals. Plastic package has Underwriters Laboratory Flammability 94V-O. DO-214AC PACKAGE MECHANICAL DATE Case: JEDEC DO214AC. Molded plastic over glass passivated junction. Terminal: Solder plated, solderable per MIL-STD-750, Method Polarity: Color band denoted positive end (cathode) except Bidirectional. Standard Packaging: 12mm tape (EIA STD RS-481). Weight: ounce, grams. MAXIMUM RATINGS AND CHARACTERISTICS Ratings at 25 ambient temperature unless otherwise specified.
