BZX55C2V4-TAP

Single Zener Diodes Overview

The BZX55C2V4-TAP is a small signal Zener diode from the Vishay BZX55-Series, housed in a DO-35 (DO-204AH) glass axial package. It features a nominal Zener voltage of 2.4 V with a tolerance range of 2.28 V to 2.56 V at a test current of 5 mA. The device exhibits low reverse leakage current (<1 µA at 2 V) and dynamic resistance values under 50 Ω (ZZ) and 100 Ω (ZZK). It operates within a junction temperature range of -65 °C to +175 °C, with a maximum power dissipation of 500 mW.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise voltage regulation
• Low reverse current level ensuring minimal standby power loss
• Very high stability across operating conditions
• Low noise performance suitable for sensitive circuits

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TAP' corresponds to the 10,000-unit ammopack configuration as defined in the ordering information. Confirm that the DO-35 package dimensions and lead specifications match your PCB footprint requirements. Ensure thermal management strategies account for the 500 mW power dissipation limit at 25 °C ambient temperature. Validate compliance with material categorization standards if required by your supply chain policies.

Single Zener Diodes Selection Notes

Select this component when a stable 2.4 V reference is required in a compact axial package. The C-series tolerance offers a wider voltage spread compared to the B-series, which may impact precision applications. Consider the negative temperature coefficient below 5 V when designing for wide thermal ranges. Evaluate the dynamic resistance limits to ensure adequate regulation under varying load currents.

Single Zener Diodes Part Context

This part belongs to the BZX55-Series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a broad voltage range from 2.4 V to 75 V in the standard DO-35 package. The BZX55C2V4-TAP specifically denotes the 2.4 V variant with C-tolerance packaged in tape-and-reel format for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX55C2V4 variants from Vishay or equivalent 2.4 V Zener diodes in DO-35 packages from other manufacturers, provided electrical parameters such as voltage tolerance, power rating, and leakage current are compatible.
