Overview
The Semitec S-101T is a surface-mount current regulating diode (CRD) designed to maintain a constant current flow despite voltage fluctuations. It features a pinch-off current of 0.1 mA and a maximum limiting voltage of 2 V. The device supports a rated power of 500 mW and operates within a temperature range of -40°C to +150°C. With a breakdown voltage of 100 V, it provides stable performance for applications requiring precise current control in compact designs.
Feature Summary
- Maintains constant current across a wide voltage range from less than 1V to 100V
- Requires only one component to replace multi-component constant current circuits
- Operates reliably under varying load resistance and ripple voltage conditions
Applications
- Constant current source for LED brightness stabilization
- Battery charge and discharge circuits
- Current source for piezoelectric actuators
- Stabilized power supply circuits
Procurement Notes
Verify the specific ordering suffix 'T' confirms the SMD reel taping format as defined in the product number explanation. Confirm the manufacturer designation matches Semitec USA Corp specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Check datasheet limits for junction temperature and allowable reverse current before integration.
Selection Notes
Select this model for low-current applications requiring 0.1 mA regulation. Consider the 500 mW rated power and 100 V maximum voltage when designing the circuit. Evaluate the temperature coefficient range of +0.10% to +2.10%/°C for thermal stability needs. Compare against higher current variants if the application demands greater amperage.
Part Context
This component belongs to the Semitec S series of current regulating diodes. It is the surface-mount equivalent to the axial E-101 part. The series offers various current ratings from 0.1 mA to 22.5 mA. All S-series parts share similar packaging and reliability characteristics.
Replacement Considerations
The axial E-101 is the direct leaded counterpart. Verify pinout orientation differences between SMD and axial packages. Ensure replacement parts meet the same 500 mW power rating and 100 V voltage limits.
