Nexperia USA Inc. BZV55-C6V8,135

Overview

BZV55-C6V8,135 from Nexperia is a ±5% tolerance silicon Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 6.8 V nominal Zener voltage at 5 mA, with 30 Ω typical differential resistance and 4.5 pF capacitance at 1 MHz. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.

For engineers reviewing the BZV55-C6V8,135 datasheet, BZV55-C6V8,135 pinout, BZV55-C6V8,135 application, or BZV55-C6V8,135 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (300 K/W to solder point), non-repetitive peak reverse power (40 W), and low-capacitance operation suitable for precision regulation and transient suppression.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain a stable 6.8 V reference across its terminals under controlled current conditions. Its low 30 Ω differential resistance ensures minimal voltage drift with load current variation, while the 1.2 mV/K temperature coefficient enables predictable thermal behavior in ambient ranges from −65 °C to +200 °C.

The device uses a planar epitaxial construction with hermetic glass encapsulation for long-term stability and moisture resistance. Its 4.5 pF junction capacitance at 0 V bias supports high-frequency noise filtering without compromising regulation accuracy in DC-coupled feedback paths.

FAQ

What is the maximum continuous reverse current this diode can handle?

The BZV55-C6V8,135 has no specified maximum continuous reverse (Zener) current in its datasheet; instead, it is limited by total power dissipation. At 6.8 V, the maximum continuous Zener current is approximately 73.5 mA (500 mW ÷ 6.8 V), assuming ambient temperature ≤50 °C on a 10×10×0.6 mm ceramic substrate. Derating applies above that temperature.

Can this Zener diode be used in place of a TVS diode for ESD protection?

No - while BZV55-C6V8,135 handles 40 W non-repetitive surges (100 μs), it is not rated for IEC 61000-4-2 ESD events (0.7–1 ns rise time, 30 A peak). Its junction capacitance (4.5 pF) and slower response make it unsuitable as primary ESD protection; it functions best as secondary clamping or precision regulation, not fast transient suppression.

How does the ±5% tolerance affect regulation accuracy in a feedback loop?

The ±5% tolerance means the actual Zener voltage falls between 6.4 V and 7.2 V at 5 mA. In a feedback loop using this diode directly (e.g., with TL431), this introduces up to ±5.9% output voltage error before compensation. For tighter regulation, use closed-loop compensation or select ±2% BZV55-B6V8 variants where accuracy is critical.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies full compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C outline supports peak temperatures up to 260 °C for ≤10 seconds, with recommended solder land dimensions of 1.70 mm × 2.25 mm (per pad) and 2.30 mm pad-to-pad spacing. Thermal resistance to solder point (300 K/W) confirms robust thermal transfer during reflow.
