E-152

Current Regulation - Diodes, Transistors Overview

The Semitec E-152 is a leaded current regulating diode (CRD) from the E series, designed to maintain constant current flow despite voltage fluctuations. It operates within an ambient temperature range of -30°C to +150°C and features a rated power of 300 mW. The device supports a maximum pulse wave voltage of 100 V and allows a reverse current up to 50 mA. The pinch-off current is specified at 1.5 mA with a typical limiting voltage of 2.0 V. The junction temperature rating reaches 150°C, ensuring stability in demanding environments.

Current Regulation - Diodes, Transistors Feature Summary

• Maintains constant current output across wide voltage ranges from less than 1V to 100V
• Requires only a single component to replace multi-part constant current circuits
• Operates reliably under significant load resistance changes and ripple voltage conditions

Current Regulation - Diodes, Transistors Applications

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific part number against official Semitec documentation to confirm package type and electrical ratings. Ensure that the procurement specifications align with the required operating temperature range and power dissipation limits. Cross-reference the manufacturer's datasheet for accurate handling and storage guidelines before ordering.

Current Regulation - Diodes, Transistors Selection Notes

Select the E-152 when a leaded axial configuration is required for applications needing a 1.5 mA regulated current. Consider the 300 mW power rating and the -30°C to +150°C operating range during thermal design. Compare performance against the SMD S-152T variant if surface mount technology is preferred for the same electrical characteristics.

Current Regulation - Diodes, Transistors Part Context

The E-152 belongs to the Semitec E series of current regulating diodes, which are characterized by their leaded axial construction. This series complements the SMD S series, offering identical electrical functionality in a through-hole format suitable for traditional PCB mounting techniques and automated insertion processes.

Current Regulation - Diodes, Transistors Replacement Considerations

The S-152T serves as the direct surface-mount equivalent within the same product family. Verify pin compatibility and thermal management requirements when transitioning between the leaded E-series and the SMD S-series packages.
