Overview
The SD1A150G is a silicon unidirectional thyristor (SIDAC) manufactured by Diodes Incorporated. It features a peak repetitive off-state voltage of 120 V and an on-state RMS current rating of 1 A at 80°C. The device operates within a junction temperature range of -40 to +125°C. Key electrical characteristics include a breakover voltage between 142 V and 157 V, a holding current maximum of 60 mA, and a peak on-state voltage of 1.5 V at 1 A. The component utilizes a JEDEC DO-15 molded plastic package with lead-free plating.
Feature Summary
- Compact DO-15 molded plastic package designed for space-saving applications
- Silicon unidirectional thyristor construction with lead-free terminal plating
- RoHS 2011/65/EU compliant component manufacturing
Applications
- Gas igniters
Procurement Notes
Verify the specific manufacturer part number against official datasheets before procurement. Confirm that the DO-15 package dimensions and thermal resistance values match the design requirements. Ensure compliance with RoHS 2011/65/EU standards if required by the target market regulations. Check for UL Recognition File E219635 status for safety certification needs.
Selection Notes
Select this component when a compact, high-voltage triggering device is needed for gas ignition circuits. The 1 A RMS current rating supports moderate load switching. Verify that the 120 V blocking voltage aligns with the circuit's peak operating limits. Consider the -40 to +125°C junction temperature range for environmental suitability.
Part Context
The SD1A150G belongs to the SIDAC family of silicon unidirectional thyristors produced by Diodes Incorporated. These devices are engineered for overvoltage protection and triggering applications. The DO-15 package provides a standardized footprint for through-hole mounting in industrial and consumer electronics.
Replacement Considerations
Consult official substitution guides from Diodes Incorporated for verified equivalents. Ensure replacement parts maintain identical DO-15 mechanical dimensions and electrical ratings such as 120 V blocking voltage and 1 A RMS current capacity.
