Overview
The SD1A180G is a silicon unidirectional thyristor manufactured by Diodes Incorporated, housed in a compact DO-15 molded plastic package. It features a peak repetitive off-state voltage (VDRM) of 150 V and an on-state RMS current rating of 1 A at 80°C. The breakover voltage (VBO) ranges from 170 V to 190 V with a maximum holding current of 60 mA. Designed for gas igniter applications, the device operates within a junction temperature range of -40°C to +125°C and supports a maximum lead solder temperature of 260°C.
Feature Summary
- Compact DO-15 package design intended to save spacing
- Silicon unidirectional thyristor construction
- Lead-free plating terminals compliant with RoHS standards
Applications
- Gas igniters
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received part matches the SD1A180G designation and DO-15 package type. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before final integration into circuit designs.
Selection Notes
Select this component when a low-cost, high-voltage trigger device is required for ignition circuits. Ensure the application voltage does not exceed the 150 V blocking limit. Verify that the thermal management strategy accommodates the specified junction temperature range and power dissipation requirements under continuous operation conditions.
Part Context
This device belongs to the SIDAC family of silicon unidirectional thyristors produced by Diodes Incorporated. These components are engineered for overvoltage protection and triggering functions. The DO-15 form factor provides a standardized footprint suitable for through-hole mounting in industrial and consumer electronics assemblies requiring robust switching capabilities.
Replacement Considerations
Consult official substitution lists for equivalent thyristors with matching VBO ranges and current ratings. Verify pinout compatibility and thermal resistance values before implementing alternative parts in existing layouts.
