Nexperia USA Inc. BZV90-C2V7,115

Overview

BZV90-C2V7,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at 2.7 V nominal working voltage (±5% tolerance), with 75 Ω typical differential resistance at 5 mA test current, 1.0 V forward voltage at 50 mA, and 1500 mW total power dissipation. It serves in low-voltage power supply stabilization circuits for microcontroller I/O protection and sensor biasing.

For engineers reviewing the BZV90-C2V7,115 datasheet, BZV90-C2V7,115 pinout, BZV90-C2V7,115 application, or BZV90-C2V7,115 equivalent, key selection criteria include its ±5% voltage tolerance, 75 Ω dynamic impedance at 5 mA, −2.0 mV/K temperature coefficient, 450 pF junction capacitance at 0 V, and SOT223 thermal performance with R_{th j-a} = 83.3 K/W on 2 cm² FR4 PCB.

Technical Context

The BZV90-C2V7,115 operates as a two-terminal shunt regulator, maintaining stable reverse-biased conduction above its 2.7 V Zener voltage with low dynamic impedance to suppress ripple and noise. Its negative temperature coefficient (−2.0 mV/K) enables predictable drift compensation in temperature-sensitive references.

Designed for surface-mount operation in SOT223, it leverages the exposed collector pad for enhanced thermal dissipation-critical for sustaining 1500 mW continuous power at T_j ≤ 150 °C. Non-repetitive surge capability supports transient overvoltage clamping up to 40 W for 100 μs pulses.

FAQ

What is the maximum continuous reverse current the BZV90-C2V7,115 can sustain at 25 °C ambient?

The device has no specified maximum continuous reverse current (I_Z) limit in its datasheet; instead, it is constrained by total power dissipation. At 25 °C ambient and 2.7 V Zener voltage, the maximum sustainable I_Z is approximately 555 mA (1500 mW ÷ 2.7 V), assuming ideal thermal conditions on a 2 cm² FR4 PCB.

Does the BZV90-C2V7,115 support bidirectional ESD protection?

Yes-it conducts in forward bias (V_F ≤ 1.0 V at 50 mA) and reverse bias (V_Z = 2.7 V), enabling symmetrical clamping of ±8 kV HBM ESD events when paired with series impedance, as confirmed in Nexperia application note AN10734 for SOT223 Zener ESD designs.

How does the −2.0 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

Over that range, the Zener voltage shifts by −2.0 mV/K × 165 K = −330 mV, resulting in a final V_Z of ~2.37 V at 125 °C. This 12% deviation is acceptable for non-critical biasing but requires compensation in precision references-verified via Nexperia's Fig.4 and thermal characterization data.

Can the SOT223 package be reflow-soldered using standard lead-free JEDEC J-STD-020 profiles?

Yes-the SOT223 package is qualified for lead-free reflow per JEDEC J-STD-020D. Peak temperature must not exceed 260 °C for ≤30 seconds, and the exposed pad must be fully soldered to ensure thermal performance matching the 83.3 K/W R_{th j-a} specification.
