Product details
Overview
BZV55-B30,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for nominal 30 V ±2 % regulation at 5 mA, with 70 Ω typical differential resistance and 30 mV/K temperature coefficient. It delivers stable reference voltage in power supply feedback loops, overvoltage protection circuits, and precision biasing networks for analog sensor interfaces.
For engineers reviewing the BZV55-B30,115 datasheet, BZV55-B30,115 pinout, BZV55-B30,115 application, or BZV55-B30,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (300 K/W junction-to-solder-point), non-repetitive surge capability (40 W @ 100 µs), and low reverse leakage (<50 nA @ 21 V).
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining a stable 30 V output across its cathode-anode terminals under reverse-bias conditions with 5 mA test current. Its regulation relies on controlled avalanche breakdown, supported by low differential resistance (70 Ω typ.) and predictable temperature coefficient (+30 mV/K).
The SOD80C package enables compact PCB layout while providing hermetic sealing for long-term stability in humid or thermally cycling environments. Thermal performance is defined with device mounted on a 10 × 10 × 0.6 mm ceramic substrate, yielding Rth(j-sp) = 300 K/W to solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 29.4 V to 30.6 V at IZ = 5 mA - ensures ±2 % regulation accuracy for precision reference applications |
| Differential Resistance (rdif) | 70 Ω typical at IZ = 5 mA - minimizes output voltage shift under load current variation |
| Temperature Coefficient (SZ) | +30 mV/K at IZ = 2 mA - enables predictable drift compensation in temperature-sensitive circuits |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - defines continuous DC power handling on standard FR4 PCB |
| Reverse Leakage Current (IR) | <50 nA at VR = 21 V - ensures negligible error current in high-impedance reference nodes |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - allows use as polarity indicator or low-drop rectifier in auxiliary paths |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; marking band denotes cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; accepts reverse-bias current to maintain VZ |
| 2 | Anode | Ground or low-impedance return path; completes regulation loop during conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct use in 30 V reference designs without trimming or calibration |
| Low 70 Ω differential resistance | Reduces output voltage deviation to <210 mV under ±3 mA load change |
| Hermetic glass SOD80C package | Guarantees long-term parameter stability in industrial humidity (85 % RH) and thermal cycling |
| 40 W non-repetitive surge rating | Clamps ESD transients (IEC 61000-4-2 Level 4) without degradation |
| 300 K/W junction-to-solder-point thermal resistance | Supports reliable operation up to 125 °C ambient when soldered to 25 mm² copper pour |
Applications
| Power Supply Reference | Sensor Biasing |
|---|---|
Use Scenario: Providing stable 30 V reference for op-amp feedback in isolated DC-DC converter secondary-side regulation. IC Role / Device Role / Timing Role: Shunt regulator establishing precise output voltage setpoint independent of load current variation. Use Value: Maintains ±0.6 % output accuracy over 10–100 mA load range due to low rdif and tight VZ tolerance. | Use Scenario: Biasing a 30 V-rated pressure transducer bridge in automotive engine control units. IC Role / Device Role / Timing Role: Stable excitation source ensuring linear sensor response across −40 °C to +125 °C ambient. Use Value: Temperature coefficient of +30 mV/K allows predictable offset correction in firmware, reducing calibration points by 40 %. |
| Overvoltage Protection | Signal-Level Clamping |
Use Scenario: Protecting 3.3 V microcontroller I/O pins from 24 V field wiring faults in industrial PLC modules. IC Role / Device Role / Timing Role: Fast-acting clamp diverting surge energy before IC damage occurs. Use Value: 40 W peak power rating handles 100 µs transients per IEC 61000-4-4, limiting voltage to ≤33 V. | Use Scenario: Limiting analog input swing to ±30 V in data acquisition front-ends interfacing with legacy instrumentation. IC Role / Device Role / Timing Role: Bidirectional clamp (with series diode) defining safe signal envelope for ADC driver stage. Use Value: Reverse leakage <50 nA avoids loading high-Z sensor outputs, preserving signal integrity above 10 MΩ source impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C30,113 | ±5 % tolerance (28.5–31.5 V), higher rdif (80 Ω typ.), same SOD80C package | Acceptable where cost sensitivity outweighs precision; unsuitable for closed-loop feedback requiring tight VZ | Select when budget constraints dominate and ±5 % regulation is acceptable in open-loop biasing. |
| MMSZ5256B-TP | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint, lower Rth(j-sp) = 250 K/W) | Better thermal performance but incompatible with dense SOD80C layouts; requires PCB redesign. | Choose only if thermal margin is critical and board space permits SOD-123 rework. |
Compared with BZV55-B30,115, the BZX55C30,113 trades regulation accuracy for cost, while MMSZ5256B-TP improves thermal dissipation at the expense of footprint compatibility-making the BZV55-B30,115 optimal for space-constrained, precision 30 V reference designs.

FAQ
What is the maximum continuous reverse current for BZV55-B30,115 at 25 °C?
The device has no specified maximum continuous reverse current; instead, it is limited by total power dissipation. At 25 °C ambient, Ptot = 500 mW implies IZ ≤ 16.7 mA (500 mW ÷ 30 V) for sustained operation. Derating applies above 50 °C ambient per the thermal characteristics table.
Can BZV55-B30,115 be used in series with another Zener for higher voltage regulation?
No-series connection is not recommended. The BZV55-B30,115 lacks matched temperature coefficients or dynamic impedance characteristics needed for stable stacked operation. Variations in SZ and rdif between units cause unequal voltage sharing and thermal runaway risk.
Is the SOD80C package compatible with standard reflow profiles for lead-free soldering?
Yes. Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The glass body withstands peak temperatures up to 260 °C for ≤60 seconds; recommended footprint matches Figure 7 in the datasheet, with 2.30 mm pad length and 0.90 mm solder land width.
How does the 30 mV/K temperature coefficient affect circuit accuracy over −40 °C to +125 °C?
Across this 165 K range, ΔVZ ≈ +4.95 V (30 mV/K × 165 K), shifting nominal 30 V to ~34.95 V at +125 °C. For high-accuracy systems, this drift must be compensated via circuit design (e.g., complementary NTC network) or firmware lookup tables calibrated per unit.
