BZT52B7V5

Single Zener Diodes Overview

The BZT52B7V5 is a small signal Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOD-123F surface mount package. It provides a nominal Zener voltage of 7.5 V with a 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 75 Ohms at a test current of 15 mA, a reverse leakage current of 0.9 µA at 5.0 V, and a forward voltage of 1.0 V maximum at 10 mA.

Single Zener Diodes Feature Summary

• Planar die construction for robust performance
• Halogen-free composition compliant with IEC 61249-2-21 standards
• Matte tin lead finish with nickel underplate for solderability
• Moisture sensitivity level 1 classification

Single Zener Diodes Applications

• Voltage regulation circuits
• Voltage reference applications
• Clipping and clamping circuits
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify the specific manufacturer datasheet version (e.g., DS_S1405026) to confirm electrical parameters match design requirements. Ensure the ordering suffix aligns with the required packaging format, such as reel quantities. Confirm compliance with RoHS directives and halogen-free specifications if mandated by project constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V reference with tight ±2% tolerance is required in a compact SMD form factor. The 500 mW power rating allows for moderate current handling compared to lower-power variants. Verify that the 75 Ohm dynamic impedance meets the noise and stability requirements of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the BZT52B series from Taiwan Semiconductor, which covers a wide Zener voltage range from 2.4 V to 75 V. All devices in this series share the same SOD-123F mechanical outline and general feature set, differing primarily in their breakdown voltage and associated impedance values.

Single Zener Diodes Replacement Considerations

Cross-reference with Vishay BZT52B7V5 or Nexperia BZT52H-B7V5 for pin-compatible alternatives. Ensure substitute parts maintain the 500 mW power dissipation and ±2% voltage tolerance specifications.
