Overview
The SD1A120GW is a silicon unidirectional thyristor (SIDAC) manufactured by Diodes Incorporated, housed in a compact DO-15 molded plastic package. It features a peak repetitive off-state voltage of 90 V and a breakover voltage range from 105 to 120 Vdc. The device supports an on-state RMS current of 1 A at 80 °C ambient temperature and can withstand a pulse on-state current of 80 A. Key electrical characteristics include a holding current under 60 mA and a typical thermal resistance of 15 °C/W. It operates within a junction temperature range of -40 to +125 °C.
Feature Summary
- Compact DO-15 package design for space-saving applications
- Defined breakover voltage range between 105 and 120 Vdc
- Low holding current requirement below 60 mA
- Lead-free plating terminals compliant with RoHS standards
Applications
- Gas igniters
- HID igniters
- Pulse generating circuits
Procurement Notes
Verify the component against the official datasheet specifications before integration. Confirm that the DO-15 package dimensions and lead-free terminal requirements align with your assembly processes. Ensure the operating environment stays within the specified thermal limits to maintain reliability. Check for any specific handling instructions regarding the silicon unidirectional thyristor structure.
Selection Notes
Select this component when a precise breakover voltage between 105 and 120 V is required for triggering applications. The 1 A RMS current rating suits moderate power switching needs. Consider the DO-15 package size if board space is constrained. Verify that the 90 V blocking voltage meets the circuit's peak repetitive off-state requirements.
Part Context
This part belongs to the SIDAC family of silicon unidirectional thyristors designed for overvoltage protection and triggering. The SD1A series typically offers robust performance in high-voltage pulse applications. The 'G' suffix indicates lead-free compliance, while 'W' often denotes tape and reel packaging options.
Replacement Considerations
Check for equivalent SIDAC devices with similar breakover voltages (105-120 V) and current ratings. Ensure replacement parts support the DO-15 package and meet the same thermal and electrical stress limits.
