E-701

Current Regulation - Diodes, Transistors Overview

The Semitec E-701 is a current regulating diode (CRD) designed to maintain a constant current flow despite voltage fluctuations. It supplies a pinch-off current of 0.7 mA at 10 V, with a minimum range of 0.6 mA and a maximum of 0.9 mA. The device operates within an allowable reverse current of 50 mA and withstands a rated pulse voltage of 100 V. It features a junction temperature limit of 150 °C and functions across an operating temperature range of -30 °C to 150 °C. The component has a rated power of 300 mW and exhibits a temperature coefficient ranging from 0.00 to -0.32 %/°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific package type required, as the E-series denotes a leaded axial configuration. Confirm that the 300 mW rated power aligns with thermal management requirements in the target application environment. Ensure the operating temperature range of -30 °C to 150 °C meets system specifications. Check datasheet limits for reverse current and breakdown voltage before finalizing integration.

Current Regulation - Diodes, Transistors Selection Notes

Select this model when a precise 0.7 mA constant current is needed without complex regulation circuitry. Consider the SMD variant if surface mount technology is preferred, noting potential differences in rated power. Evaluate thermal derating curves if ambient temperatures exceed standard conditions. Verify compatibility with Zener diodes for higher voltage applications requiring stabilized currents.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the Semitec CRD series, which includes various pinch-off current ratings from 0.1 mA to 22.5 mA. The E-series specifically refers to the leaded axial package version, distinct from the S-series surface mount options. These devices are categorized under current regulating diodes used for simple constant current generation in electronic circuits.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other Semitec CRDs with identical 0.7 mA ratings, such as the S-701T for surface mount applications. Cross-brand replacements require matching pinch-off current, voltage ratings, and package dimensions. Verify thermal characteristics and temperature coefficients to ensure equivalent performance in existing designs.
