BZT52B16-E3-18

Single Zener Diodes Overview

The BZT52B16-E3-18 is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It operates within the SOD-123 surface-mount package and provides a nominal Zener voltage of 16 V with a tight tolerance of ±2%. The device is rated for a total power dissipation of up to 500 mW at an ambient temperature of 25 °C, with a maximum junction temperature of 150 °C. Electrical characteristics include a test current of 5 mA, a reverse leakage current of 100 nA at 12 V, and a dynamic resistance of 40 Ω at the test current.

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix requirements for tape and reel packaging. Confirm compliance with regional environmental directives such as RoHS before finalizing procurement. Ensure the component meets the required thermal management specifications for the intended operating environment.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow ±2% tolerance band. Consider the SOD-123 footprint constraints during PCB layout design. Evaluate the thermal resistance parameters to ensure adequate heat dissipation under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the BZT52 series of small signal Zener diodes designed for general-purpose applications. The series covers a wide range of nominal voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter tolerance variant compared to the standard 'C' series.

Single Zener Diodes Replacement Considerations

Cross-reference with other Vishay BZT52B16 variants or equivalent Zener diodes offering identical 16 V nominal voltage and ±2% tolerance. Verify package compatibility and thermal ratings before substitution.
