Overview
The ZDT1147TC is a dual NPN medium-power Darlington transistor array manufactured by Diodes Incorporated. It features two independent NPN Darlington pairs housed in an SM-8 (SOT-223-8) surface-mount package. The device is rated for a collector-emitter voltage (VCEO) of 120 V and a continuous collector current (IC) of 1 A per die. With a maximum power dissipation of 2 W, it provides high current gain suitable for switching and amplification applications requiring robust performance in compact form factors.
Feature Summary
- Integrates two independent NPN Darlington pairs within a single compact package
- Provides high current gain capability through Darlington configuration
- Rated for 120 V collector-emitter voltage and 1 A continuous collector current per element
- Designed for surface-mount assembly using the SM-8 (SOT-223-8) footprint
Applications
- High-voltage switching circuits
- Driver stages for relays or solenoids
- Power management control logic
- Industrial automation interface circuits
Procurement Notes
Verify the specific suffix 'TC' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement source provides documentation confirming the SM-8 package type and 120 V rating. Cross-reference the part number with Diodes Incorporated's latest product announcements to avoid obsolete variants.
Selection Notes
Select this component when a dual NPN Darlington configuration is required for high-voltage switching up to 120 V. The SM-8 package offers a balance between power handling and board space efficiency. Consider the 1 A per-die current limit and 2 W power dissipation when designing thermal management solutions for the application environment.
Part Context
This part belongs to Diodes Incorporated's ZDT series of digital and analog transistor arrays. These components integrate multiple transistors into single packages to reduce board space and simplify assembly. The ZDT1147TC specifically targets applications needing dual NPN Darlington outputs in a surface-mount format.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Verify pinout and electrical ratings before considering alternative manufacturers.
