BZT52B2V4-G

Single Zener Diodes Overview

The BZT52B2V4-G is a general-purpose Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOD-123 surface-mount package. It features a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%, ranging from 2.35 V to 2.45 V at a test current of 5 mA. The device supports a total power dissipation of 410 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum dynamic impedance of 100 Ω and a leakage current of 50 µA at 1.0 V.

Single Zener Diodes Procurement Notes

Verify the specific suffix '-G' confirms RoHS compliance and halogen-free status as documented in the datasheet. Confirm the marking code '2WX' matches the physical component received. Ensure the ordering code corresponds to the 3K/7" reel packing format if bulk procurement is required. Cross-reference the manufacturer's version H2002 for any potential specification updates.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference near 2.4 V is required with strict tolerance limits. The SOD-123 package is ideal for space-constrained designs. Consider the 410 mW power rating for thermal management in enclosed environments. Verify that the 5 mA test current aligns with the target circuit's operating conditions to ensure accurate voltage regulation.

Single Zener Diodes Part Context

This part belongs to the BZT52B series of general-purpose Zener diodes offered by Taiwan Semiconductor. The series covers a wide voltage range from 2.4 V to 75 V, all utilizing the same SOD-123 footprint. The 'B' designation indicates a ±2% tolerance variant, distinguishing it from standard tolerance versions. This consistency allows for flexible design scaling across different voltage requirements within the same package constraint.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 2.4 V nominal voltage, ±2% tolerance, and SOD-123 package. Verify equivalent power dissipation ratings of at least 410 mW. Check for compatible thermal resistance and leakage current specifications to ensure circuit performance parity.
