Features, Applications

Surface Mount TRANSZORB Transient Voltage Suppressors

Case: JEDEC DO-214AA (SMB) molded plastic over passivated junction Terminals: Solder plated, solderable per MIL-STD-750, Method 2026 Polarity: For uni-directional types the band denotes the cathode, which is positive with respect to the anode under normal TVS operation Standard Packaging: 12mm tape (EIA STD RS-481) Weight: 0.003 ounces, 0.093 grams Packaging Codes Options (Antistatic): 2K per Bulk box, 750 per 7" plastic Reel (12mm tape), 3.2K per 13" plastic Reel (12mm tape), 32K/carton

Features

Low profile package with built-in strain relief for surface mounted applications Glass passivated junction Low inductance Excellent clamping capability Repetition rate (duty cycle): 0.01% Fast response time: theoretically (with no parisitic inductance) less than 1ps from 0 Volts to V(BR) for unidirectional and 5ns for bidirectional types High temperature soldering: 250C/10 seconds at terminals Plastic package has Underwriters Laboratory Flammability Classificaion 94V-0
