BZX85C3V3-TAP

Single Zener Diodes Overview

The BZX85C3V3-TAP is a silicon planar power Zener diode from the Vishay BZX85 series, designed for voltage stabilization and clipping applications. It features a DO-41 axial glass case with a maximum power dissipation of 1.3 W at 25 °C ambient temperature. The nominal Zener voltage is 3.3 V with a tolerance range of 3.1 V to 3.5 V (±5%). Key electrical parameters include a dynamic resistance of less than 20 Ω at a test current of 80 mA, a reverse leakage current of less than 40 µA at 1 V, and an admissible Zener current of 300 mA. The device operates within a junction temperature range of -55 °C to +175 °C.

Single Zener Diodes Feature Summary

• Silicon planar construction optimized for high-power voltage regulation and signal clipping tasks.
• Graded according to international E 24 standard voltage values for standardized circuit integration.
• Robust thermal performance supporting up to 1.3 W power dissipation in through-hole configurations.

Single Zener Diodes Applications

• Voltage stabilization circuits
• Signal clipping applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'TAP' corresponds to the ammo pack packaging option containing 5,000 units per pack, as distinct from the 'TR' reel variant. Confirm compliance with RoHS3 directives and ensure the component meets AEC-Q101 automotive qualification standards if required for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference with ±5% tolerance is required in a through-hole package capable of handling 1.3 W. Consider the negative temperature coefficient typical for low-voltage Zener diodes in precision designs. Ensure the lead length allows for adequate heat sinking or verify that the operating conditions remain within the specified thermal resistance limits.

Single Zener Diodes Part Context

This part belongs to the BZX85 series of silicon planar power Zener diodes manufactured by Vishay Semiconductors. The series utilizes a DO-41 glass case suitable for axial mounting. The 'C' suffix indicates a ±5% voltage tolerance grade, while the 'TAP' suffix specifies the ammo pack packaging format rather than the standard tape and reel configuration.

Single Zener Diodes Replacement Considerations

Substitutes must match the 3.3 V nominal voltage, 1.3 W power rating, and DO-41 axial package. Verify that alternative manufacturers provide equivalent dynamic resistance and leakage current specifications to maintain circuit stability.
