E-352

Current Regulation - Diodes, Transistors Overview

The Semitec USA Corp E-352 is a current regulating diode (CRD) belonging to the SMD and Leaded series, designed to maintain constant current flow despite voltage fluctuations. It operates within a wide voltage range from less than 1V to 100V. The device features a rated power of 300 mW for the E-series and supports a maximum rated voltage of 100 V for models up to E-562. The pinch-off current at 10 V is typically 3.50 mA, with a minimum of 3.00 mA and a maximum of 4.1 mA. The limiting current is 3.2 mA, and the temperature coefficient ranges from -0.20 to -0.47 %/°C. It functions reliably across an operating temperature range of -30°C to 150°C.

Current Regulation - Diodes, Transistors Feature Summary

• Maintains constant current flow regardless of applied voltage fluctuations or load resistance changes
• Requires only a single component to create a constant current circuit compared to multi-component solutions
• Operates over a wide voltage range from less than 1V to 100V

Current Regulation - Diodes, Transistors Applications

• Constant current source for LED brightness stabilization
• Battery charge and discharge circuits
• Current source for proximity sensors and other sensors
• Stabilized power supply circuits

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific package type required, as the E-352 designation corresponds to the leaded variant in official documentation, while the S-352T denotes the surface-mount version. Confirm that the 300 mW rated power aligns with thermal management requirements in the target application environment. Ensure compatibility with the specified operating temperature range of -30°C to 150°C during system design validation.

Current Regulation - Diodes, Transistors Selection Notes

Select the E-352 when a leaded package is preferred for through-hole mounting applications requiring stable current regulation. Compare the 3.50 mA typical pinch-off current against circuit requirements to ensure adequate drive capability. Consider the negative temperature coefficient characteristics when designing for high-temperature environments to prevent current drift beyond acceptable limits.

Current Regulation - Diodes, Transistors Part Context

The E-352 is part of Semitec's broader Current Regulating Diode portfolio, which includes both SMD and axial leaded options. It shares functional similarities with the S-352T but differs in physical packaging. This component belongs to the E-series characterized by a 300 mW rated power, distinguishing it from the higher-power S-series variants.

Current Regulation - Diodes, Transistors Replacement Considerations

The S-352T serves as the direct surface-mount equivalent with identical electrical specifications. For higher current needs, consider the E-452 or E-562. For lower current applications, the E-272 or E-202 may be suitable alternatives.
