Nexperia USA Inc. BZV55-C2V4,115

Overview

BZV55-C2V4,115 from Nexperia is a ±5% tolerance silicon Zener diode in a hermetically sealed SOD80C glass package, rated for 2.4 V nominal Zener voltage at 5 mA, with 500 mW total power dissipation and 40 W non-repetitive peak reverse power capability. It serves as a low-power voltage reference or regulation element in bias networks, overvoltage protection clamps, and precision threshold detection circuits in industrial sensor interfaces and power supply feedback paths.

For engineers reviewing the BZV55-C2V4,115 datasheet, BZV55-C2V4,115 pinout, BZV55-C2V4,115 application, or BZV55-C2V4,115 equivalent, this page delivers verified Zener voltage tolerance, differential resistance, thermal resistance, reverse leakage current at 1 V, and SOD80C package mechanical dimensions - all confirmed from Nexperia's official Rev. 5 product data sheet dated 26 January 2011.

Technical Context

This Zener diode operates in reverse breakdown mode with a nominal 2.4 V regulation voltage at I_Z = 5 mA, exhibiting a typical differential resistance of 600 Ω and a negative temperature coefficient of −3.5 mV/K to −1.6 mV/K. Its low 50 μA reverse leakage at V_R = 1 V enables stable reference performance in low-current biasing applications.

The device uses a small hermetically sealed glass SOD80C surface-mount package with 1.6 mm × 3.7 mm footprint and 0.3 mm profile, optimized for reflow soldering per IPC-J-STD-020. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous power handling without heatsinking.

FAQ

What is the maximum continuous Zener current for BZV55-C2V4,115 at 25 °C?

The absolute maximum forward current is 250 mA, but continuous Zener operation is limited by power dissipation. At 25 °C ambient and no heatsinking, the 500 mW total power rating permits up to 208 mA (500 mW ÷ 2.4 V) in ideal thermal conditions. In practice, derating begins above 50 °C ambient per the 400 mW limit specified at T_amb ≤ 50 °C.

How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

The BZV55-C2V4 exhibits a negative temperature coefficient between −3.5 mV/K and −1.6 mV/K. Over a 165 K range, this introduces up to ±275 mV (−1.67 mV/K × 165 K) of voltage shift from nominal 2.4 V - approximately ±11.5 %. This must be accounted for in precision references; compensation techniques include using complementary diodes or selecting higher-voltage Zeners with flatter coefficients.

Can BZV55-C2V4,115 be used in series or parallel configurations?

Series connection is acceptable for higher composite Zener voltages, provided current-sharing resistors balance leakage. Parallel connection is strongly discouraged due to mismatched Zener impedances and thermal runaway risk - even minor V_Z variation causes one diode to dominate conduction and overheat. Use single-diode configurations or integrated multi-Zener arrays instead.

What is the recommended PCB pad layout for optimal thermal performance in SOD80C?

Nexperia specifies a reflow soldering footprint with 2.30 mm × 4.30 mm solder lands and 0.90 mm spacing (two lands). To improve thermal dissipation, extend copper pours beyond the pads using thermal vias to inner ground planes. Avoid narrow traces; minimum 0.5 mm width per land is advised. The 380 K/W junction-to-ambient rating assumes standard FR-4 with no additional copper; adding 100 mm² of 1 oz copper per side reduces R_th(j-a) by ~30 %.
