Product details

Overview

BZV90-C2V4,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at 2.4 V nominal working voltage (±5% tolerance), with 1500 mW total power dissipation, 70–100 Ω differential resistance, and −3.5 to −1.6 mV/K temperature coefficient. It serves in low-voltage power supply stabilization circuits for microcontroller I/O protection and sensor biasing.

For engineers reviewing the BZV90-C2V4,115 datasheet, BZV90-C2V4,115 pinout, BZV90-C2V4,115 application, or BZV90-C2V4,115 equivalent, key selection criteria include its 2.4 V Zener voltage at 5 mA test current, 450 pF diode capacitance at 0 V reverse bias, 50 μA max reverse leakage at 1.0 V, and SOT223 thermal resistance of 83.3 K/W under standard PCB mounting.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and input fluctuations. Its E24-standardized 2.4 V nominal Zener voltage is specified at 5 mA test current, with differential resistance of 70–100 Ω indicating moderate regulation stiffness under dynamic load conditions.

The device exhibits a negative temperature coefficient (−3.5 to −1.6 mV/K), confirming its use in low-voltage reference applications where thermal drift compensation may be required. Its non-repetitive peak reverse power dissipation reaches 40 W for 100 μs pulses, supporting transient overvoltage clamping in conjunction with series current limiting.

Key Specifications

Applications

Microcontroller I/O Protection

Sensor Bias Reference

Use Scenario: Clamping 3.3 V or 2.5 V MCU GPIO pins against ESD or overvoltage transients during hot-plug or noisy environment operation.

IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown as shunt voltage limiter, placed between I/O line and ground.

Use Value: Limits pin voltage to ≤2.6 V (max V_Z) while sinking up to 400 mA forward current, preventing latch-up or oxide damage.

Use Scenario: Providing stable 2.4 V bias voltage for analog sensors (e.g., thermistors, RTDs) in battery-powered environmental monitors.

IC Role / Device Role / Timing Role: Precision DC voltage reference source, delivering regulated voltage independent of supply ripple.

Use Value: Maintains <±5% accuracy over temperature with 70–100 Ω dynamic impedance, minimizing sensor measurement error.

Low-Voltage LDO Pre-regulator

Industrial Signal Conditioning

Use Scenario: Pre-stabilizing unregulated 3.3 V rail before feeding low-dropout linear regulator to reduce dropout margin and improve PSRR.

IC Role / Device Role / Timing Role: Shunt regulator establishing clean intermediate reference node upstream of LDO input.

Use Value: Reduces input ripple by >20 dB at 100 kHz due to 450 pF junction capacitance and low dynamic impedance.

Use Scenario: Level-shifting and clamping 0–2.4 V analog signals from industrial transducers prior to ADC sampling.

IC Role / Device Role / Timing Role: Bidirectional signal clamp - forward-conducting below 1.0 V, Zener-clamping above 2.6 V.

Use Value: Ensures signal stays within ADC input range while tolerating ±10% supply variation and 50 μA leakage-induced offset.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C2V4	Same 2.4 V Zener voltage but in SOT23 package; lower P_tot = 300 mW; higher r_dif ≈ 120 Ω	Not suitable for >150 mW continuous dissipation; limited thermal headroom on standard PCB	Select when board space is critical and power demand is <100 mW; avoid for sustained regulation loads.
MMSZ4678	2.4 V Zener in SOD-123; P_tot = 500 mW; r_dif = 90 Ω; T_j max = 150 °C same	Lower thermal mass and higher R_{th j-a} (~200 K/W) limits duty-cycle handling in surge scenarios	Prefer for cost-sensitive consumer designs where 40 W pulse rating is unnecessary and footprint is constrained.

Compared with BZX84-C2V4 and MMSZ4678, the BZV90-C2V4,115 delivers 3× higher continuous power and superior thermal robustness in SOT223, making it optimal for industrial regulation where reliability under sustained load or occasional surge is mandatory.

FAQ

What is the maximum continuous reverse current this diode can handle at 2.4 V?

The BZV90-C2V4,115 does not specify a maximum continuous reverse current at exactly 2.4 V; instead, its Zener operation is characterized at I_Ztest = 5 mA. Continuous reverse current is limited by thermal constraints: at 25 °C ambient on a 2 cm² FR4 PCB, P_tot = 1500 mW implies I_Z ≤ 625 mA at 2.4 V, but practical design limits I_Z to ≤400 mA per absolute maximum ratings.

Can this diode be used in parallel for higher current handling?

No - Zener diodes like the BZV90-C2V4,115 exhibit manufacturing spread in V_Z (±5%, i.e., 2.2–2.6 V), causing current hogging if paralleled without individual ballast resistors. The datasheet does not recommend or characterize parallel operation, and thermal runaway risk is high without matched devices and external balancing.

Is the SOT223 package lead-free and RoHS compliant?

Yes - Nexperia confirms the BZV90-C2V4,115 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOT223 package uses lead-free matte tin (Sn) termination, and the device carries Nexperia's standard "Pb-free" marking per JEDEC J-STD-609.

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

At 2.4 V nominal, the BZV90-C2V4,115 has a typical temperature coefficient of −2.5 mV/K. Over a 165 °C range, this yields ~−413 mV total drift - meaning V_Z drops from ~2.6 V at −40 °C to ~2.2 V at +125 °C. For precision applications, this drift must be compensated via circuit design or calibration.
