Nexperia USA Inc. BZV90-C5V6,115

Overview

BZV90-C5V6,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at 5.6 V nominal working voltage with ±5% tolerance, 15 Ω typical differential resistance at 5 mA test current, and 1.5 W total power dissipation. It serves in power supply feedback loops, overvoltage protection clamping, and analog reference circuits requiring stable reverse breakdown under industrial ambient conditions.

For engineers reviewing the BZV90-C5V6,115 datasheet, BZV90-C5V6,115 pinout, BZV90-C5V6,115 application, or BZV90-C5V6,115 equivalent, key selection criteria include its 5.6 V Zener voltage with low tempco (+1.2 mV/K), SOT223 thermal performance (R_{th j-a} = 83.3 K/W), 40 W non-repetitive peak reverse power capability, and dual-cathode configuration enabling robust PCB layout for high-current regulation.

Technical Context

This Zener diode operates in reverse-biased breakdown mode with tightly controlled V_Z = 5.2–6.0 V at I_Ztest = 5 mA, exhibiting a positive temperature coefficient of +1.2 mV/K - optimal for compensating negative drift in adjacent circuitry. Its differential resistance of ≤40 Ω ensures minimal output voltage variation under load changes.

The SOT223 package integrates a large copper collector pad for enhanced thermal conduction, supporting continuous operation up to T_j = 150 °C when mounted on 2 cm² FR4 double-sided copper. Non-repetitive surge handling (I_ZSM = 1 A, t_p = 100 μs) enables transient overvoltage suppression without degradation.

FAQ

What is the maximum continuous reverse current the BZV90-C5V6,115 can sustain at 25 °C?

The device does not specify a maximum continuous reverse current; instead, it is rated by power dissipation. At 25 °C ambient, with proper PCB copper area (2 cm²), it sustains up to 268 mA continuously (1500 mW ÷ 5.6 V) while maintaining junction temperature below 150 °C. Derating applies above 25 °C per R_{th j-a} = 83.3 K/W.

Can the dual cathode pins (2 and 4) be used independently?

No - pins 2 and 4 are internally connected as a single cathode node. They are provided for enhanced current handling and thermal spreading; using them separately violates the internal construction and may cause uneven current distribution or localized overheating. Both must be soldered to the same net.

Is the BZV90-C5V6,115 suitable for use in automotive AEC-Q200 applications?

While the BZV90-C5V6,115 meets industrial temperature and reliability requirements (T_j = −65 to +150 °C, qualified per JEDEC standards), it is not officially AEC-Q200 stress-tested or certified. For automotive-grade designs, Nexperia offers the PZUx series, which carries full AEC-Q200 qualification and identical electrical specs.

How does the +1.2 mV/K temperature coefficient affect regulation accuracy over −40 to +125 °C?

Over this 165 K range, the Zener voltage shifts by +198 mV (1.2 × 165), resulting in a 5.6 V nominal becoming ~5.798 V at +125 °C. This 3.5% drift is predictable and usable in compensated designs; for tighter stability, pair with a negative-tempco component or use in closed-loop feedback where error amplifier corrects residual drift.
