Nexperia USA Inc. BZV55-C8V2,135

Overview

BZV55-C8V2,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 8.2 V nominal regulation at 5 mA with ±5 % tolerance, 700 nA reverse leakage at VR = 5 V, and 400 mW total power dissipation at Tamb ≤ 50 °C. It serves as a precision reference or voltage clamp in low-current analog signal conditioning and power rail stabilization circuits.

For engineers reviewing the BZV55-C8V2,135 datasheet, BZV55-C8V2,135 pinout, BZV55-C8V2,135 application, or BZV55-C8V2,135 equivalent, key selection criteria include its 8.2 V Zener voltage tolerance, differential resistance of 40–80 Ω (IZ = 5 mA), temperature coefficient of +3.2 to +6.2 mV/K, and suitability for non-repetitive surge handling up to 40 W at tp = 100 μs.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load or supply conditions. Its regulation accuracy depends on specified test current (IZ = 5 mA), junction temperature (Tj = 25 °C), and thermal resistance to ambient (Rth(j-a) = 380 K/W).

It exhibits a positive temperature coefficient (+3.2 to +6.2 mV/K) across IZ = 1–5 mA, indicating increasing VZ with rising temperature - critical for biasing stability in temperature-sensitive references. The SOD80C package enables compact PCB layout while maintaining hermetic sealing for long-term reliability in industrial environments.

FAQ

What is the maximum continuous operating current for BZV55-C8V2,135?

The device supports a maximum forward current of 250 mA per absolute maximum ratings, but its Zener regulation is specified at IZ = 5 mA. For continuous operation in breakdown, the practical limit is derived from Ptot = 400 mW at Tamb ≤ 50 °C, yielding ~48.8 mA max (400 mW ÷ 8.2 V). Exceeding this risks thermal runaway due to positive SZ.

How does the temperature coefficient affect circuit performance?

The +3.2 to +6.2 mV/K coefficient means VZ increases with junction temperature - e.g., a 50 °C rise adds 160–310 mV to nominal 8.2 V. This must be accounted for in precision references; however, it enables predictable compensation when paired with negative-drift components like silicon diodes or resistors.

Can BZV55-C8V2,135 replace BZV55-B8V2 in existing designs?

Yes, but with trade-offs: BZV55-B8V2 offers ±2 % tolerance (7.84–8.16 V) versus ±5 % (7.7–8.7 V) for the -C variant. Differential resistance is also lower in the -B version (40 Ω typ vs. 40–80 Ω). Use -C only where looser regulation and higher rdif are acceptable - e.g., non-critical clamping rather than metrology-grade references.

What soldering profile is recommended for SOD80C packaging?

Nexperia specifies reflow soldering per JEDEC J-STD-020, with peak temperature ≤260 °C and time above liquidus ≤45 seconds. The SOD80C footprint requires 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing; wave soldering is supported using the documented 2.70 mm × 4.90 mm pad layout with 1.90 mm track clearance.
