Overview
The NSD070ALT1G is a small signal switching diode array manufactured by onsemi. It features a common anode configuration with two independent diodes housed in a single SOT-23 (TO-236-3, SC-59) surface-mount package. The device supports a peak reverse voltage of 70 V and a maximum forward current of 200 mA. It is rated for a surge current of 500 mA and operates within a temperature range of -55°C to +150°C. The component is Pb-free and available in tape and reel packaging.
Feature Summary
- Common anode dual diode architecture for compact circuit integration
- Small signal switching capability optimized for high-speed applications
- Automotive-grade reliability qualification
Applications
- General purpose rectification in low-power circuits
- Clamping and protection in automotive electronics
- Signal switching in consumer devices
Procurement Notes
Verify the specific ordering suffix to ensure compliance with environmental requirements, such as lead-free status. Confirm that the requested quantity matches the standard tape and reel packaging specifications provided by the manufacturer. Cross-reference the date code and device code markings on the physical components against official documentation to authenticate the source and prevent counterfeit risks during procurement.
Selection Notes
Select this component when a common anode configuration is required for space-constrained designs utilizing SOT-23 packages. Ensure the application voltage does not exceed the 70 V peak reverse rating and that the forward current remains within the 200 mA limit. Consider the thermal performance and junction temperature limits if operating in high-temperature environments or under continuous load conditions.
Part Context
This part belongs to the small signal switching diode category from onsemi. It represents a transition from Fairchild Semiconductor product lines following corporate restructuring. The SOT-23 form factor allows for automated surface mount assembly, making it suitable for high-volume manufacturing processes in portable and automotive electronic systems requiring reliable rectification.
Replacement Considerations
Direct substitutes may include other common anode diode arrays in SOT-23 packages with equivalent voltage and current ratings. Verify pinout compatibility and electrical parameters before substitution. Consult official cross-reference lists for approved alternatives.
