BZX55F3V9-TAP

Single Zener Diodes Overview

The BZX55F3V9-TAP is a silicon unidirectional voltage regulator diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 3.9 V with a tight tolerance of ±1%. The component is rated for a maximum power dissipation of 500 mW and operates within an ambient temperature range of -65°C to +175°C. It utilizes the DO-35 axial glass package, weighing approximately 130 mg. The device is supplied in Ammopack tape packaging, containing 10,000 units per pack.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise voltage regulation
• Low reverse current level ensuring minimal leakage
• Very high stability under varying conditions
• Low noise performance suitable for sensitive circuits

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'TAP' corresponds to the Ammopack (52 mm tape) packaging configuration rather than standard reel or cut tape formats. Confirm the ±1% tolerance designation associated with the 'F' series code matches the design requirements. Ensure the DO-35 glass package dimensions align with the target PCB footprint constraints.

Single Zener Diodes Selection Notes

Select this component when tight voltage tolerance is critical, as the F-series offers superior accuracy compared to standard C-series variants. The wide operating temperature range supports deployment in harsh environments. The axial leaded format facilitates through-hole mounting techniques. Consider the low reverse current and noise characteristics for applications requiring high signal integrity.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX55 series of Zener diodes, which are characterized by their glass passivated junction and robust mechanical construction. The series is designed for general-purpose voltage regulation tasks. The BZX55F variant specifically targets applications demanding tighter voltage tolerances than the standard commercial grade parts provide.

Single Zener Diodes Replacement Considerations

BZX55C3V9-TAP: Offers similar electrical parameters but with a wider ±5% tolerance instead of ±1%. BZX55A3V9/TR: Provides equivalent voltage and power ratings but utilizes different packaging options such as tape and reel.
