Product details
Overview
BZV55-C3V9,115 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 3.9 V nominal Zener voltage at 5 mA, 400 mW total power dissipation at Tamb ≤ 50 °C, and 3 µA reverse leakage at VR = 1 V - used for low-power voltage reference and regulation in sensor biasing, power supply feedback, and analog signal conditioning circuits.
For engineers reviewing the BZV55-C3V9,115 datasheet, BZV55-C3V9,115 pinout, BZV55-C3V9,115 application, or BZV55-C3V9,115 equivalent, key selection considerations include its ±5 % VZ tolerance, 400 mW derated power handling, 400 Ω typical differential resistance at IZ = 5 mA, and cathode-anode polarity marking on the SOD80C body.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or input conditions. Its temperature coefficient of −2.5 mV/K (typical) indicates negative drift with rising junction temperature, requiring thermal-aware placement in precision references.
Designed for low-current regulation (IZ = 1–5 mA), it exhibits 400 Ω typical dynamic impedance at 5 mA and 450 pF junction capacitance at 1 MHz and 0 V reverse bias - making it suitable for DC and low-frequency (<100 kHz) stabilization, not RF or high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.7 V to 4.1 V at IZ = 5 mA - defines usable regulation range for 3.3 V system references |
| Differential Resistance (rdif) | 400 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | 3 µA max at VR = 1 V - ensures minimal quiescent current in standby-biased circuits |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - limits continuous operating current to ~102 mA at 3.9 V |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - requires PCB copper area or thermal relief management above 100 mW |
| Junction Temperature Range | −65 °C to +200 °C - supports industrial and extended-temperature embedded operation |
| Package | SOD80C glass SMD - hermetic seal enables long-term stability and moisture resistance |
Pinout & Package
SOD80C is a 2-terminal surface-mount glass package with axial lead frame, 3.3–3.7 mm length, 1.45–1.60 mm width, and 0.3 mm height. The black band denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; accepts reverse bias for Zener conduction |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not required (e.g., non-critical biasing) |
| Hermetically sealed glass construction | Prevents moisture ingress and parameter drift over time - critical for 10+ year field reliability |
| Low differential resistance (400 Ω typ.) | Minimizes output voltage shift under load changes up to ±10 mA variation |
| Non-repetitive peak power rating (40 W) | Withstands transient surges (100 µs square wave) without degradation in surge-protected inputs |
| Wide VZ range coverage (2.4–75 V) | Part of standardized E24 series - simplifies BOM consolidation across multiple voltage rails |
Applications
| Power Supply Feedback | Sensor Bias Reference |
|---|---|
Use Scenario: Stabilizing feedback voltage in linear regulator ICs or op-amp-based shunt regulators. IC Role / Device Role / Timing Role: Provides precise reference voltage to error amplifier input, enabling output voltage setpoint control. Use Value: Maintains ±5 % output regulation over line/load variations without external trimming components. |
Use Scenario: Supplying stable excitation voltage to resistive temperature detectors (RTDs) or bridge sensors. IC Role / Device Role / Timing Role: Acts as passive voltage source for sensor excitation, minimizing self-heating and drift. Use Value: Delivers <3 µA leakage and <400 Ω impedance to limit sensor measurement error to <0.1 % FS. |
| Analog Signal Clamping | Microcontroller I/O Protection |
Use Scenario: Limiting analog input swing to prevent ADC saturation or op-amp rail-to-rail overload. IC Role / Device Role / Timing Role: Shunts excess voltage above 3.9 V to ground via reverse conduction. Use Value: Clamps transients within 100 ns (limited by junction capacitance) while surviving 40 W surge peaks. |
Use Scenario: Protecting 3.3 V GPIO pins against ESD or overvoltage events exceeding VDD. IC Role / Device Role / Timing Role: Functions as low-leakage bidirectional clamp when paired with series resistor. Use Value: Limits pin voltage to 3.9 V + VF (0.9 V) = 4.8 V max, well below 5 V absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C3V9,115 | Same VZ and tolerance, but in SOD123 package with higher Ptot (500 mW) and lower rdif (300 Ω) | Better thermal performance and tighter regulation; requires larger PCB footprint | Select when higher power margin or improved load regulation is needed |
| MMSZ5226B-TP | 3.9 V ±5 %, but in SOD-123 with 500 mW rating and 150 Ω rdif; RoHS-compliant, no halogen restriction note | Lower impedance improves regulation accuracy; slightly different marking and tape packaging | Choose for legacy-compatible replacement with enhanced stability and compliance documentation |
Compared with BZV55-C3V9,115, BZT52-C3V9,115 offers higher power headroom and lower dynamic impedance in a physically larger package, while MMSZ5226B-TP delivers superior regulation precision and broader compliance coverage - both require layout review for pad geometry and thermal relief.

FAQ
What is the maximum continuous forward current for BZV55-C3V9,115?
The device is not intended for continuous forward conduction. Its absolute maximum forward current is 250 mA per limiting values table, but forward operation exceeds design intent - Zener function requires reverse bias. Forward voltage is specified only at 10 mA (≤0.9 V) for polarity verification.
Can BZV55-C3V9,115 be used in place of a 3.3 V LDO for powering ICs?
No - it lacks current-sourcing capability and regulation headroom. With 400 mW max dissipation, it supports only ~102 mA at 3.9 V, and cannot maintain regulation under variable load. It serves as a reference or shunt element, not a power source.
How does the −2.5 mV/K temperature coefficient affect circuit accuracy?
At 3.9 V nominal, a 50 °C junction rise causes ~125 mV drop in VZ, or ~3.2 % error. For <0.5 % total error, ambient temperature must stay within ±8 °C of calibration point, or compensation circuitry must be added.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. Peak temperature must not exceed 260 °C, and time above 217 °C must be limited to 60–150 seconds. Footprint dimensions match standard SOD80C land patterns (2.30 × 4.30 mm solder lands).
