Transient Voltage
Suppressor Diode Array
SOT−23 Dual Common Anode Zeners
for ESD Protection
These dual monolithic silicon zener diodes are designed for
applications requiring transient overvoltage protection capability. They
are intended for use in voltage and ESD sensitive equipment such as
computers, printers, business machines, communication systems,
medical equipment and other applications. Their dual junction common
anode design protects two separate lines using only one package. These
devices are ideal for situations where board space is at a premium.
Features
• SOT−23 Package Allows Either Two Separate Unidirectional
Configurations or a Single Bidirectional Configuration
• Working Peak Reverse Voltage Range − 12 V
• Peak Power − 450 W (8 X 20 ms)
• Low Leakage
• Flammability Rating UL 94 V−0
• ESD Rating:
IEC 61000−4−2 (ESD) 15 kV (air) 8 kV (contact)
IEC 61000−4−4 (EFT) 50 A (5 x 50 ns)
IEC 61000−4−5 (Lighting) 12 A (8 x 20 ms)
• Human Body Model − Up to 16 kV
• Machine Model − Up to 400 V
• Pb−Free Package is Available
Mechanical Characteristics:
CASE: Void-free, transfer-molded, thermosetting plastic case
FINISH: Corrosion resistant finish, easily solderable
MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES:
260°C for 10 Seconds
Package designed for optimal automated board assembly
Small package size for high density applications
