BZX84C5V1LT116

Single Zener Diodes Overview

The BZX84C5V1LT116 is a surface-mount Zener diode manufactured by Rohm Semiconductor, housed in an SOT-323 (SC-70) package. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device operates within a maximum power dissipation of 350 mW at ambient temperatures up to 70°C. Key electrical specifications include a maximum Zener impedance of 22 ohms and a leakage current not exceeding 1 µA at the rated voltage. The component supports a continuous forward current of 200 mA and withstands peak pulse currents as defined by its thermal characteristics.

Single Zener Diodes Feature Summary

• Compact SOT-323 surface-mount packaging for space-constrained designs
• Stable voltage regulation with tight tolerance for precision applications
• Low leakage current characteristics ensuring minimal power loss

• Biasing networks in transistor amplifier stages

Single Zener Diodes Procurement Notes

Verify the specific suffix LT116 against the manufacturer's latest datasheet to confirm tape-and-reel quantity and binning details. Ensure compatibility with standard reflow soldering profiles specified for the SOT-323 package. Cross-reference pinout configurations if substituting into existing footprints to prevent misalignment during assembly processes.

Single Zener Diodes Selection Notes

Select this component when a low-profile voltage regulator is required for mobile or handheld devices. Consider the 5.1 V nominal value for logic level interfacing where precise threshold control is necessary. Evaluate the 350 mW power rating against expected thermal loads in enclosed enclosures to ensure reliable long-term operation without derating issues.

Single Zener Diodes Part Context

This part belongs to Rohm's BZX84 series of small-signal Zener diodes designed for general-purpose voltage regulation. The series offers various voltage options in compact packages to support modern miniaturization trends. The BZX84C5V1 variant specifically targets applications needing reliable clamping and reference functions in consumer electronics and industrial control modules.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 5.1 V Zener voltage, SOT-323 package, and equivalent power dissipation ratings. Verify that alternative components maintain similar impedance and leakage specifications to ensure circuit performance parity without redesigning surrounding passive elements.
