uln2803 darlington arrays

Description

The ULx2803A/LW and ULx2804A / LW are the standard Darlington arrays. The outputs are capable of sinking 500 mA and will withstand at least 50 V in the off state. Outputs may be paralleled for higher load current capability. The ULx2823A / LW and ULx2824A / LW will withstand 95 V in the off state.
These Darlington arrays are furnished in 18-pin dual in-line plastic packages (suffix ‘A’) or 18-lead small-outline plastic packages (suffix ‘LW’). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. Prefix ‘ULN’ devices are rated for operation over the temperature range of -20°C to +85°C; prefix ‘ULQ’ devices are rated for operation to -40°C.

SMDA05 Datasheet

Description

The SMDA05 series of TVS arrays are designed to provide undirectional protection for sensitive electronics from damage or latch-up due to ESD, lightning, and other voltage-induced transient events.

TVS diodes are solid-state devices designed specifically for transient suppression. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage and no device degradation.

Features

1. Working voltage : 5 V
2. Transient protection for data lines to
(1) IEC 61000-4-2 (ESD) ± 15 kV (air), ± 8 kV (contact)
(2) IEC 61000-4-4 (EFT) 40 A (5/50 ns)
(3) IEC 61000-4-5 (Lightning) 12 A (8/20 µs)
4. Unidirectional protection
5. Small SO-8 package
6. Protects four I/O lines
7. Low leakage current
8. Low operating and clamping voltages
9. Solid-state silicon-avalanche technology
