Transient Voltage Suppression Diodes Surface Mount – 600W > SMA6L series SMA6L Series Description The SMA6L series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. SMA low profile package has the same electronical performance as the SMB package but with lowest height profiles (1.1mm) in the industry. Features Maximum Ratings and Thermal Characteristics •S MA low profile package: less than 1.1 mm •S ame power as standard SMB devices (600 W) •F ootprint compatibility with standard SMA and SMB products (easy to layout) • Typical failure mode is short from over-specified voltage or current • Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c • IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact) •E SD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2) •E FT protection of data lines in accordance with IEC 61000-4-4 (IEC801-4) (TA=25 C unless otherwise noted) O Parameter Symbol Value Unit Peak Pulse Power Dissipation at TA=25ºC by 10x1000µs waveform (Fig.2)(Note 1), (Note 2) PPPM 600 W Power Dissipation on infinite heat sink at TA=50OC PM(AV) 3 W Peak Forward Surge Current, 8.3ms Single Half Sine Wave (Note 3) IFSM 60 A Maximum Instantaneous Forward Voltage at 25A for Unidirectional only VF 3.5V V TJ , TSTG -65 to 150 °C Typical Thermal Resistance Junction to Lead RuJL 35 °C/W Typical Thermal Resistance Junction to Ambient RuJA 200 °C/W Operating Junction and Storage Temperature Range Notes: 1. Non-repetitive current pulse, per Fig.4 and derated above TA=25ºC per Fig. 3. 2.Mounted on 5.0x5.0mm copper pad to each terminal. 3.Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional device only. .• Low inductance, excellent clamping capability • Fast response time: typically less than 1.0ns from 0 Volts to VBR min • Built-in strain relief • Glass passivated junction • Typical IR less than 1µA above 12V • High temperature soldering: 260°C/40 seconds at terminals • Typical maximum temperature coefficient ΔVBR = 0.1% x VBR@25°C x ΔT • Matee tin lead–free plated • Halogen free and RoHS compliant Applications TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
