Overview
The SD09A240E is a silicon bidirectional thyristor (SIDAC) from the SD09A-E series manufactured by Lite-On Semiconductor Corporation. It features a DOF41 molded plastic case with lead-free plating and RoHS compliance. The device has a peak repetitive off-state voltage of 180 to 180 volts, an on-state RMS current of ±0.9 amperes, and a peak non-repetitive surge current of ±4.0 amperes. It operates within a junction temperature range of -40 to +125 degrees Celsius and offers high pulse current capability.
Feature Summary
- Glass passivation ensures reliable operation
- High pulse current capability
- Lead-free plating with matte tin finish
Applications
- High pressure sodium vapor lighting
- Strobes and flashers
- Ignitors
- High voltage regulators
- Pulse generators
Procurement Notes
Verify the manufacturer designation as Lite-On Semiconductor Corporation or LSC based on the provided datasheet documentation. Confirm that the component meets RoHS 2002/95/EC standards and utilizes lead-free matte tin terminal plating. Ensure the ordering suffix matches the specific voltage rating required for the application design.
Selection Notes
Select this component when a bidirectional trigger device with a breakover voltage near 220 to 250 volts is required. Verify that the circuit can accommodate the maximum dynamic holding current of 100 mA. Ensure the thermal management supports the specified junction temperature limits and that the package dimensions fit the intended PCB layout constraints.
Part Context
This part belongs to the SD09A-E SIDAC series, which includes variants with different breakover voltages such as 105V, 120V, 130V, 160V, and 220V. All members share the same DOF41 package and electrical characteristics except for the specific breakdown voltage thresholds defined by the ordering code.
Replacement Considerations
Compatible substitutes include other parts from the SD09A series with matching voltage ratings, such as the SD09A220E. Cross-reference specifications for peak repetitive off-state voltage and on-state current to ensure functional equivalence in the target circuit design.
FAQ
What is the breakover voltage range for the SD09A240E?
The breakover voltage ranges from a minimum of 220 volts to a maximum of 250 volts at a test current of 35uA.
What is the maximum dynamic holding current?
The maximum dynamic holding current is 100 mA under sine wave conditions at 50 to 60 Hz.
