Product details
Overview
BZV90-C3V6,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation in low-to-medium current applications. It delivers a nominal Zener voltage of 3.6 V (±5%), with differential resistance ≤90 Ω at 5 mA test current, 1.5 W total power dissipation, and operates up to 150 °C junction temperature - used in power supply feedback loops and analog sensor biasing circuits.
For engineers reviewing the BZV90-C3V6,115 datasheet, BZV90-C3V6,115 pinout, BZV90-C3V6,115 application, or BZV90-C3V6,115 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (83.3 K/W), non-repetitive surge capability (40 W), and SOT223 thermal pad layout compatibility with PCB copper area design.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its E24-standardized 3.4–3.8 V range at 5 mA test current. Its temperature coefficient of −2.4 mV/K (typical) ensures predictable drift behavior over −65 to +150 °C ambient, critical for stable reference generation in industrial environments.
The device uses a planar silicon junction structure optimized for low dynamic impedance (≤90 Ω) and low capacitance (≤450 pF at 0 V), enabling effective noise suppression in feedback paths while maintaining fast transient response during load-step events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, min 3.4 V / max 3.8 V at IZtest = 5 mA - defines regulated output level in shunt regulator topologies |
| Differential Resistance (rdif) | ≤90 Ω at IZtest = 5 mA - determines regulation stiffness and line/load regulation error |
| Power Dissipation (Ptot) | 1500 mW at Tamb = 25 °C on 2 cm² FR4 double-sided copper - sets maximum continuous DC power handling |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs square wave - enables transient overvoltage clamping without failure |
| Junction Temperature (Tj) | −65 to +150 °C - supports operation in extended industrial and automotive under-hood environments |
| Thermal Resistance (Rth j-a) | 83.3 K/W - quantifies thermal path efficiency from junction to ambient on standard PCB layout |
| Reverse Current (IR) | ≤5 μA at VR = 1.0 V - ensures low leakage in high-impedance bias networks |
Pinout & Package
SOT223 plastic surface-mount package with integrated collector pad for enhanced thermal conduction; 4-lead configuration (pins 1 and 3 anode, pins 2 and 4 cathode) optimized for PCB heat spreading.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Power Supply Feedback Reference | Sensor Biasing Circuit |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck-boost converters via optocoupler-coupled feedback loop. IC Role / Device Role: Shunt voltage reference providing precise 3.6 V threshold to TL431 or optocoupler LED drive circuit. Use Value: Maintains ±1% output regulation across line/load/temperature due to tight VZ tolerance and low rdif. | Use Scenario: Providing stable excitation voltage to resistive temperature detectors (RTDs) or bridge-based pressure sensors. IC Role / Device Role: Low-noise, low-drift DC bias source replacing higher-cost bandgap references in cost-sensitive industrial sensors. Use Value: Delivers <5 μA leakage and <90 Ω dynamic impedance - minimizing measurement offset and gain errors. |
| Overvoltage Protection Clamp | Microcontroller I/O Level Translation |
Use Scenario: Protecting 3.3 V logic inputs against transient surges from inductive loads or ESD events. IC Role / Device Role: Fast-acting clamp limiting voltage to 3.6 V before damage occurs to downstream CMOS inputs. Use Value: Withstands 40 W non-repetitive peak power for 100 μs - absorbs energy from typical IEC 61000-4-4 bursts without degradation. | Use Scenario: Translating 5 V UART signals to 3.3 V microcontroller GPIOs in mixed-voltage embedded systems. IC Role / Device Role: Passive level shifter using forward-biased Zener drop (VF ≈ 0.7 V) combined with reverse-biased regulation. Use Value: Achieves reliable 3.3 V logic-high threshold with <1.0 V forward voltage at 50 mA - avoids timing skew of active translators. |
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-C3V6 | Same 3.6 V nominal Zener voltage but in SOT23 package; lower Ptot (300 mW); higher rdif (100 Ω) | Limited to low-power signal-level regulation; unsuitable for >100 mA shunt current | Select when board space is constrained and power demand is <150 mW |
| MMSZ4685 | 3.6 V Zener in SOD-123; Ptot = 500 mW; rdif = 130 Ω; no thermal pad | Lower thermal performance - Rth j-a ≈ 270 K/W limits sustained current in compact layouts | Select for cost-sensitive consumer applications where 500 mW headroom suffices |
Compared with BZX84-C3V6 and MMSZ4685, BZV90-C3V6,115 provides 3× higher power handling and 40% lower dynamic impedance in a thermally robust SOT223 package - making it optimal for industrial power supplies and sensor interfaces requiring long-term stability under thermal stress.

FAQ
What is the maximum continuous reverse current this Zener can handle at 3.6 V?
The BZV90-C3V6,115 is rated for continuous Zener current up to 400 mA, derived from its 1500 mW power rating and 3.6 V nominal voltage (IZmax ≈ Ptot/VZ). Actual safe operating current depends on PCB thermal design - with 2 cm² copper area, it sustains full rating at 25 °C ambient.
Does this part have a specified forward voltage, and how is it used?
Yes - forward voltage is specified as ≤1.0 V at 50 mA forward current. This parameter enables dual-mode use: reverse-biased for regulation and forward-biased for level shifting or LED current limiting in mixed-signal circuits where bidirectional clamping is required.
How does the temperature coefficient affect regulation accuracy over −40 to +85 °C?
With a typical temperature coefficient of −2.4 mV/K, the Zener voltage drifts approximately −120 mV over a 50 K rise (e.g., −40 to +10 °C). At 3.6 V nominal, this represents ~3.3% deviation - acceptable for non-precision applications but requires compensation in metrology-grade designs.
Can this diode replace older Philips/NXP BZV90-C3V6 parts marked with different date codes?
Yes - BZV90-C3V6,115 is the direct Nexperia successor to the legacy NXP/Philips BZV90-C3V6, retaining identical electrical specifications, SOT223 mechanical outline, and thermal characteristics. The "115" suffix denotes tape-and-reel packaging per JEDEC standard, fully compatible with legacy assembly processes.
