Overview
The SD09A105E is a silicon bidirectional thyristor (SIDAC) from the SD09A-E series, manufactured by Lite-On Semiconductor Corporation. It features a peak repetitive off-state voltage of 105V and an RMS on-state current rating of 0.9A. The device offers high pulse current capability with a critical rate of rise of on-state current (di/dt) of 120 A/us. Packaged in a JEDEC DOF41 molded plastic case with matte tin finish terminals, it operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Glass passivation ensures reliable operation under various conditions
- High pulse current capability for robust performance
- Low dynamic holding current limits power consumption during standby
Applications
- High pressure sodium vapor lighting circuits
- Strobes and flasher units
- Ignitor systems
- High voltage regulators
- Pulse generators
- Triggering gates of SCRs and Triacs
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions remain within specified temperature ranges to maintain material integrity before assembly.
Selection Notes
Select this component when a breakover voltage near 105V is required for overvoltage protection or triggering applications. Consider the 0.9A RMS current limit and DOF41 package dimensions for board layout constraints. Evaluate thermal resistance characteristics against expected ambient operating temperatures.
Part Context
Part of the SD09A-E SIDAC series offering voltages from 105V to 240V. Designed as a cost-effective solution for high-voltage switching and protection tasks. Shares common mechanical specifications and packaging standards across the series for simplified inventory management.
Replacement Considerations
Cross-reference with other SIDAC devices offering similar 105V breakover voltage and DOF41 footprint. Verify matching electrical parameters including di/dt ratings and holding currents before substitution.
FAQ
What is the maximum lead solder temperature?
The maximum lead solder temperature is 260°C, applied for a maximum duration of 10 seconds at a lead length of 1/16 inch from the case.
How is the breakover voltage defined for this model?
The breakover voltage is measured at a test current (IBO) of 35uA, with a typical value of 105V and a maximum of 110V for the SD09A105E.
What is the peak non-repetitive surge current rating?
The peak non-repetitive surge current is rated at ±4.0 Amps for a 60 Hz one-cycle sine wave at a junction temperature of 125°C.
