Features, Applications
SMS05C thru SMS24C 4 LINE BIDIRECTIONAL or 5 LINE UNIDIRECTIONAL TVSarray TM

DESCRIPTION This 6 pin 4-line bidirectional or 5-line unidirectional array is designed for use in applications where protection is required at the board level from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and other induced voltage surges that can damage sensitive circuitry. These arrays are used to protect 4 discrete lines utilizing pins 1,3,4,6 with a common pin 5 configuration to ground for bidirectional protection and pin 2 is not connected. It may also be used to protect 5 lines utilizing pins 1,3,4,5,6 with a common pin 2 connection to ground. These Transient Voltage Suppressor (TVS) diode arrays protect 5 volt components such as DRAM's SRAM's CMOS, HCMOS, HSIC, and low voltage interfaces to 24 volts. Because of the physical size, weight and protection capabilities, this product is ideal for use in but not limited to miniaturized electronic equipment such as hand held instruments, computers, computer peripherals and cell phones.

ELECTRICAL CHARACTERISTICS BIDIRECTIONAL (See Notes for Unidirectional**)

STAND OFF PART NUMBER DEVICE MARKING VOLTAGE V WM VOLTS MAX S15C S24C BREAKDOWN VOLTAGE @1 mA VOLTS MIN CLAMPING VOLTAGE @ 1 Amp (FIGURE 2) VOLTS MAX CLAMPING VOLTAGE @ 5 Amp (FIGURE 2) VOLTS MAX STANDBY CURRENT WM A MAX CAPACITANCE (f=1 MHz) C pF TYP TEMPERATURE COEFFICIENT V BR aVBR

* CLAMPING VOLTAGE @3.6 Amps for both bidirectional and unidirectional Standoff and Breakdown Voltages for Unidirectional will 0.6 V lower and capacitance will be twice that shown in the table above. All other maximum characteristic values for unidirectional are the same as shown above for bidirectional. Note: Transient Voltage Suppressor (TVS) product is normally selected based on its stand off voltage VWM. Product selected voltage should be equal to or greater than the continuous peak operating voltage of the circuit to be protected.

Rated stand off voltage: Maximum dc voltage that can be applied over the operating temperature range. Vwm must be selected to be equal or be greater than the operating voltage of the line to be protected Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current Clamping Voltage: Maximum clamping voltage across the TVS device when subjected to a given current at a pulse time of 20 s. Standby Current: Leakage current at VWM. Capacitance: Capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in Pico Farads.
