Nexperia USA Inc. BZV55-C3V3,115

Overview

BZV55-C3V3,115 from Nexperia is a 3.3 V ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for low-power voltage regulation and reference functions in consumer and industrial power supplies.

For engineers reviewing the BZV55-C3V3,115 datasheet, BZV55-C3V3,115 pinout, BZV55-C3V3,115 application, or BZV55-C3V3,115 equivalent, this page delivers verified Zener voltage (3.3 V), differential resistance (350 Ω at I_Z = 5 mA), reverse current (5 µA at V_R = 1 V), thermal resistance (300 K/W junction-to-solder point), and SOD80C package mapping - all confirmed from Nexperia's official Rev. 5 product data sheet.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable 3.3 V output across varying load currents, with a negative temperature coefficient of −3.5 to −2.4 mV/K ensuring predictable drift under thermal variation. Its low 350 Ω differential resistance at 5 mA enables tight regulation in low-current bias networks.

The device uses a planar epitaxial construction in a hermetically sealed glass package, supporting reliable operation up to 200 °C storage temperature and 200 °C junction temperature. It is optimized for DC voltage reference, overvoltage protection, and signal-level clamping in space-constrained SMD designs.

FAQ

What is the maximum continuous reverse current this diode can sustain at 3.3 V?

The BZV55-C3V3,115 is not rated for continuous reverse current at its Zener voltage; instead, it specifies a maximum total power dissipation of 500 mW. At 3.3 V, this corresponds to a theoretical maximum steady-state Zener current of approximately 152 mA (500 mW ÷ 3.3 V), but derating per ambient temperature and PCB thermal design is required - actual usable current is typically limited to 20–50 mA for reliability.

Can this Zener diode be used in place of a 3.3 V LDO regulator?

No - the BZV55-C3V3,115 is a shunt regulator requiring a series current-limiting resistor and cannot source load current like an LDO. It maintains voltage only by sinking excess current; it provides no active pass element, dropout control, or load regulation. Use only for low-current references (<10 mA), feedback networks, or clamping - never as a primary power rail regulator.

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 × 2.25 mm (cathode) and 1.70 × 2.25 mm (anode), and 0.90 mm solder mask opening per pad as defined in Figure 7 of the datasheet.

How does the −2.4 mV/K temperature coefficient affect circuit performance at 85 °C?

From 25 °C to 85 °C (ΔT = 60 K), the Zener voltage shifts by −2.4 mV/K × 60 K = −144 mV, resulting in a V_Z of approximately 3.156 V. This 4.4 % drop is within the ±5 % initial tolerance band and remains predictable, enabling first-order compensation in analog references where absolute accuracy is secondary to monotonic drift behavior.
