FEATURES
DEVICES FOR BIPOLAR APPLICATION For surface mounted applications in order to optimize board space. Low profile package. Built-in strain relief. Glass passivated junction. Low inductance. Excellent clamping capability. Repetition Rate (duty cycle): 0.01%. Fast response time: typically less than 1.0ps from 0 volt to VBR for Unidirectional types. Typical IR less than 1μA above 10V. High Temperature soldering: 260°C/10 seconds at terminals. SMA/DO-214AC Case: JEDEC DO-214AC. Molded plastic over glass passivated junction. Terminal: Solder plated, solderable per MIL-STD-750, Method 2026. Polarity: Color band denotes cathode except Bidirectional. Standard Packaging: 12mm tape (EIA STD RS-481). We ight: 0.002 ounce, 0.061 grams. For Bidirectional use CA suffix for type P4SMA6.8CA through type P4SMA550CA;
