BZT52B3V9S

Single Zener Diodes Overview

The BZT52B3V9S is a small signal Zener diode from the Taiwan Semiconductor BZT52B series, housed in an SOD-323F surface-mount package. It provides a nominal Zener voltage of 3.90 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 200 mW and operates within a junction temperature range of -65°C to +150°C. Electrical testing specifies a test current of 5 mA for voltage characterization and a leakage current of 2.7 µA at 1 V reverse voltage.

Single Zener Diodes Feature Summary

• Offers high precision voltage regulation with a standard ±2% tolerance on Zener voltage.
• Utilizes a compact SOD-323F plastic package suitable for automated assembly processes.
• Constructed with planar die technology for reliable performance in general-purpose applications.

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage references
• Adapters
• On-board DC/DC converters

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., R9 or RR) to confirm reel size and tape specifications before procurement. Confirm RoHS compliance status and halogen-free compound availability if required by project standards. Ensure the requested quantity aligns with standard packing configurations to avoid partial reel handling issues during manufacturing.

Single Zener Diodes Selection Notes

Select this component when precise low-voltage regulation is required in space-constrained designs. The ±2% tolerance makes it suitable for sensitive reference circuits compared to wider tolerance alternatives. Verify that the 200 mW power rating meets the thermal requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the BZT52B series of small signal Zener diodes manufactured by Taiwan Semiconductor. The series covers a wide voltage range from 2.4 V to 75 V, all sharing the same SOD-323F mechanical footprint and 200 mW power dissipation capability. This allows for design flexibility while maintaining consistent board layout parameters across different voltage requirements.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' SOD-323F Zener diodes rated for 3.9 V with ±2% tolerance. Ensure equivalent power dissipation and thermal resistance characteristics are met. Verify that alternative parts comply with the same moisture sensitivity level and soldering temperature profiles.
