Nexperia USA Inc. BZV55-C6V2,135

Overview

BZV55-C6V2,135 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 6.2 V nominal regulation at 5 mA, with 40 Ω typical differential resistance and 3 µA max reverse leakage at 4 V. It delivers stable low-power voltage reference and overvoltage protection in space-constrained consumer and industrial power rails.

For engineers reviewing the BZV55-C6V2,135 datasheet, BZV55-C6V2,135 pinout, BZV55-C6V2,135 application, or BZV55-C6V2,135 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and real-world use cases for precision biasing and clamping circuits.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 6.2 V reference across load variations, with low 40 Ω differential resistance ensuring minimal voltage shift under ±1 mA current change. Its temperature coefficient of +0.4 mV/K (typical) enables predictable drift compensation in ambient-temperature-stable designs.

Designed for transient suppression, it withstands non-repetitive 40 W peak reverse power dissipation for 100 µs square-wave pulses at T_j = 25 °C, while total continuous power dissipation is limited to 400 mW at T_amb ≤ 50 °C - reflecting its role as a low-duty-cycle protection element rather than a primary regulator.

FAQ

What is the maximum continuous forward current rating for BZV55-C6V2,135?

The absolute maximum forward current is 250 mA per the datasheet limiting values table. However, this device is intended for reverse-bias Zener operation; forward conduction should be avoided in normal use as it serves no regulation function and risks thermal overstress beyond its 400 mW ambient-limited dissipation.

Can BZV55-C6V2,135 be used in parallel for higher power handling?

No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging when paralleled. Even matched units will not share current evenly due to differential resistance mismatch and thermal runaway risk. Use a single higher-power Zener or active regulation instead.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The recommended footprint (Figure 7) uses 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing; peak temperature must not exceed 260 °C for ≤10 seconds to avoid glass-to-metal seal degradation.

How does temperature affect the 6.2 V regulation voltage in practical use?

At 5 mA test current, the typical temperature coefficient is +0.4 mV/K, meaning voltage increases ~4 mV per 10 °C rise. Over –40 °C to +125 °C, total drift is approximately ±65 mV - well within the ±5 % (±310 mV) tolerance band, confirming suitability for non-critical biasing where absolute precision is secondary to stability.
