Nexperia USA Inc. BZV55-C16,135

Overview

BZV55-C16,135 from Nexperia is a ±5 % tolerance silicon Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 16 V nominal working voltage at 5 mA test current, 75 Ω typical differential resistance, and 500 mW total power dissipation. It provides stable reference voltage in low-power linear regulation circuits for industrial sensor signal conditioning and microcontroller I/O protection.

For engineers reviewing the BZV55-C16,135 datasheet, BZV55-C16,135 pinout, BZV55-C16,135 application, or BZV55-C16,135 equivalent, this page delivers verified electrical parameters, thermal behavior under surge conditions, cathode/anode terminal mapping, and validated alternative parts for precision voltage reference design.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 16 V reference across its terminals with a temperature coefficient of +10.4 mV/K at 5 mA and 25 °C junction temperature. Its low 75 Ω differential resistance ensures minimal output voltage variation under load current changes up to 250 mA forward current rating.

The device uses a planar epitaxial construction with hermetic glass encapsulation, enabling reliable operation over −65 °C to +200 °C storage temperature and 1.5 A non-repetitive peak reverse current capability under 100 µs square-wave pulses at 25 °C prior to surge.

FAQ

What is the maximum continuous reverse current the BZV55-C16,135 can sustain without degradation?

The BZV55-C16,135 has no specified maximum continuous reverse current rating; its safe operating limit is defined by power dissipation. At 16 V Zener voltage, continuous current must be limited to ≤31.25 mA to stay within the 500 mW total power dissipation limit at T_amb ≤ 50 °C on a ceramic substrate. Exceeding this causes junction temperature rise beyond 200 °C, risking permanent parametric shift.

How does the +10.4 mV/K temperature coefficient affect regulation accuracy over a −40 °C to +85 °C ambient range?

With a +10.4 mV/K coefficient, the BZV55-C16,135 exhibits a total voltage shift of +1.30 V across a 125 K temperature span (−40 °C to +85 °C), resulting in ±4.06 % deviation from nominal 16 V. This requires system-level compensation in precision applications, such as adding a negative-TC resistor in series or calibrating at two temperatures.

Can the BZV55-C16,135 replace a BZX85-C16 in an existing design?

No - BZX85-C16 is a 1.3 W through-hole Zener in DO-41 package with 100 Ω differential resistance and different thermal characteristics. Substituting BZV55-C16,135 introduces 75 % lower power handling and 2× higher thermal resistance (380 K/W vs. ~150 K/W), risking thermal runaway under identical load conditions. Board redesign and derating analysis are mandatory.

What soldering profile is recommended for the SOD80C package during reflow assembly?

Nexperia specifies a peak reflow temperature of 260 °C for 10 seconds maximum, with ramp-up rate ≤3 K/s and ramp-down rate ≤6 K/s. The SOD80C footprint requires 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing; exceeding 260 °C risks glass-to-metal seal fracture and irreversible leakage current increase above 100 nA.
