SMPZ3919B-E3/84A

Single Zener Diodes Overview

The SMPZ3919B-E3/84A is a surface mount power voltage-regulating diode from Vishay General Semiconductor, part of the eSMP series. It features a nominal Zener voltage of 5.6 V with a 5% tolerance range (5.32 V to 5.88 V) at a test current of 66.9 mA. The device operates in a single configuration within an SMP (DO-220AA) package, measuring 3.61 mm by 2.18 mm with a typical height of 1.15 mm. It supports a maximum DC Zener current of 268 mA and dissipates up to 500 mW at 25 °C ambient temperature or 1500 mW at a lead temperature of 75 °C. The component withstands operating junction and storage temperatures ranging from -65 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and compliance status. Confirm that the E3 suffix indicates matte tin plated leads solderable per J-STD-002 and JESD 22-B102. Ensure the M3 variant meets JESD 201 class 1A whisker test requirements if applicable to the specific order code.

Single Zener Diodes Selection Notes

Select this component for designs requiring a compact surface mount voltage reference with low thermal resistance. Consider the 5.6 V nominal output and 268 mA maximum current capability when sizing heat dissipation paths. Verify compatibility with standard SOP pad layouts and ensure the operating environment stays within the specified -65 °C to +150 °C temperature range.

Single Zener Diodes Part Context

This device belongs to the SMPZ39XB series, which covers Zener voltages from 5.6 V to 43 V. All parts in this series share the same SMP (DO-220AA) mechanical footprint and similar electrical characteristics, differing primarily in their specific breakdown voltage ratings and corresponding test currents defined in the datasheet tables.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include SMPZ3919B-M3/84A. Other voltage variants such as SMPZ3920B or SMPZ3918B may be considered if different voltage levels are acceptable, provided they maintain the same package and electrical constraints.
