BZT52B11

Single Zener Diodes Overview

The BZT52B11 is a small signal Zener diode from the Taiwan Semiconductor BZT52B series, housed in an SOD-123F surface-mount package. It provides a nominal Zener voltage of 11 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a dynamic impedance of 20 Ohms at a test current of 5 mA and a maximum reverse leakage current of 90 µA.

Single Zener Diodes Feature Summary

• Offers precise voltage regulation with a standard ±2% tolerance on the nominal Zener voltage.
• Utilizes a flat lead SOD-123 small outline plastic package designed for surface mount applications.
• Constructed with matte tin plating over a nickel barrier, ensuring compliance with RoHS directives and halogen-free standards.

Single Zener Diodes Applications

• General-purpose voltage reference circuits
• Low-current general regulation functions
• Protection against voltage transients

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., RHG) to confirm packaging details such as reel size or halogen-free compound status. Confirm that the component meets the required moisture sensitivity level and thermal soldering specifications for your assembly process. Ensure compatibility with the designated footprint dimensions provided in the mechanical data section.

Single Zener Diodes Selection Notes

Select this component when a stable 11 V reference is required with high precision. The ±2% tolerance makes it suitable for applications demanding tighter voltage control than standard 5% devices. Consider the 500 mW power rating and low thermal resistance for efficient heat dissipation in compact designs.

Single Zener Diodes Part Context

This part belongs to the BZT52B series, which covers a wide Zener voltage range from 2.4 V to 75 V. All members of this family share the same SOD-123F package and 500 mW power dissipation capability, differing primarily in their specific breakdown voltage and associated impedance values.

Single Zener Diodes Replacement Considerations

Compatible substitutes include BZT52B11S-TP, BZT52-B11 ST/R13, and BZT52B11 V. Verify that alternative parts match the 11 V nominal voltage, ±2% tolerance, and SOD-123F package dimensions.
