Silicon Avalanche Diodes Axial Leaded High Power Automotive Transient Voltage Suppressors RoHS SLD Series The SLD series is specifically designed for automotive applications, available in both unidirectional and bidirectional. The SLD 10U is designed to be used in series, for example three 10Us in series for a 30 volt working; this configuration will provide a very high power (a multiple of 3) capability and is a far superior solution than using devices in parallel, which will require closely matched devices in order to prevent ‘current hogging’ and consequently, damage to the device. FEATURES • RoHS Compliant • 2200 Watts Peak Power rated with 100µS/150mS pulse (applies to a single device) • 50,000 Watts Peak Pulse Power based on 8/20µS (applies to a single device) • UL 94V-0 Flammability classification APPLICATION • Designed to protect sensitive electronics which operate within an automotive system, such as: sound systems, satellite navigation, climate control, engine management, stability control, ABS etc. Agency Approvals: Recognized under the Components Program of Underwriters Laboratories. Agency File Number: E128662 ABSOLUTE MAXIMUM RATINGS @25˚C case temp (unless otherwise noted) SYMBOL PARAMETER PPP Peak pulse power 100µ/150m sec. Pulse 8/20µ sec. Pulse PM (AV) Steady state power dissipation, lead length 9.5mm, TL - 85 (note1) Vf Maximum instantaneous forward voltage @ 100amps (note 2) VALUE UNIT 2,200 50,000 Watts Watts 6.3 Watts 3.5 Volts °C °C Tj Junction temperature -55 to +150 Tstg Storage temperature -55 to +175 Note 1. Mounted on copper pad area 40mm square. Note 2. Using 300 microsecond square pulse; applies to unidirectional only, and a single device only. For devices used in series, this value should be multiplied by the number of devices. 6 Mounting Position: Polarity: ORDERING INFORMATION SLD Terminal: U 0 1 8 SILICON DIODE ARRAYS Mechanical Specifications: Weight: Case: 0.07 ounce, 2.1 gram Molded plastic over glass passivated junction Any Color band denotes positive end (cathode) except Bipolar Plated Axial leads, solderable per MIL-STD-750, Method 2026 Voltage Bi-Directional Packaging Options T = Tape and reeled (800 pcs) w w w. l i t t e l f u s e . c o m 305 Silicon Avalanche Diodes Axial Leaded High Power Automotive Transient Voltage Suppressors RoHS SLD™ Series Package Outline Dimensions Characteristics @25˚C case temp (unless otherwise noted) Part Number Case Style P600 1.0 (25.4) MIN. 0.360 (9.1) 0.340 (8.6) DIA. volts volts volts mA SLD16-018 16 18.0 22.0 1.0 10.0 SLD24U-017 SLD24-018 24 25.0 30.0 1.0 10.0 SLD10U-017 SLD10-018 10 11.8 13.0 5.0 10.0 3 x SLD 10U in series 30 35.4 39.0 5.0 10.0 BI SLD16U-017 It Maximum leakage current (Ir) @ Vr max µA Note 3.
