SD1A210GW1 is listed in the Scrs range at ChipApex. The manufacturer field lists Diodes Incorporated. Its product description is THYRISTOR DO-15 AMMO 2K. Review the specifications below when checking this part for your BOM.
The SD1A210GW is a high-voltage silicon bidirectional thyristor (SIDAC) manufactured by Diodes Incorporated. It operates with an RMS current of 1 A and features a breakover voltage range of 201 to 219 Vdc, with a typical value of 210 V. The device supports a peak repetitive off-state voltage of ±180 V and a holding current under 65 mA. Packaged in a compact DO-15 axial leaded format, it functions within a junction temperature range of -40°C to +125°C.
Verify the specific manufacturer designation when sourcing this component, as historical documentation may reference LSC or other entities. Confirm that the DO-15 package dimensions align with board layout requirements. Ensure the operating environment remains within the specified thermal limits to maintain reliability and prevent damage during high-current surge events.
Select this component for applications requiring precise voltage triggering thresholds between 201 V and 219 V. The bidirectional nature makes it suitable for AC line protection or ignition systems. Verify that the required holding current and surge ratings meet the circuit's operational demands before integration into the final design.
This SIDAC belongs to a family of high-voltage silicon bidirectional thyristors designed for robust switching applications. The DO-15 package provides mechanical stability and adequate spacing for high-voltage isolation. These devices are commonly utilized in industrial and consumer electronics where reliable pulse generation or ignition triggering is necessary.
Ensure any substitute part matches the 201–219 V breakover voltage range and 1 A RMS current rating. Verify compatibility with the DO-15 footprint and confirm that the replacement device supports the same bidirectional operation and thermal characteristics.
