Product details
Overview
BZV55-B12,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation at 12 V nominal (±2 % tolerance). It delivers stable reverse breakdown with 11.8–12.2 V working voltage at IZ = 5 mA, 85 Ω typical differential resistance, and −2.0 to +10.0 mV/K temperature coefficient. Used in power supply feedback loops, overvoltage protection, and analog reference circuits.
For engineers reviewing the BZV55-B12,115 datasheet, BZV55-B12,115 pinout, BZV55-B12,115 application, or BZV55-B12,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and validated alternatives for voltage reference design.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a specified nominal Zener voltage of 12 V at 5 mA test current, exhibiting low dynamic impedance (50–150 Ω) and controlled temperature drift. Its hermetic SOD80C glass package ensures long-term stability and moisture resistance critical for industrial-grade references.
It supports non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses and total continuous power dissipation of 400 mW at Tamb ≤ 50 °C. Reverse leakage remains ≤100 nA at VR = 8 V, enabling low-error biasing in high-impedance nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.8–12.2 V at IZ = 5 mA - defines precise regulation point for feedback or clamping |
| Differential Resistance (rdif) | 50–150 Ω (typ. 85 Ω) - determines output voltage variation under load current changes |
| Temperature Coefficient (SZ) | −2.0 to +10.0 mV/K - quantifies voltage drift across operating junction temperature range |
| Reverse Leakage (IR) | ≤100 nA at VR = 8 V - ensures minimal error current in high-Z reference paths |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage suppression without failure |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines forward conduction loss when used bidirectionally |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height; cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-bias terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5242B (ON Semiconductor) | 12 V ±5 % tolerance; 100 Ω rdif; SOT-23 package; higher thermal resistance (450 K/W) | Lower accuracy; less stable under thermal cycling due to plastic package | Select when cost sensitivity outweighs voltage precision and long-term drift requirements |
| BZX84-C12 (Nexperia) | 12 V ±5 % tolerance; 100 Ω rdif; same SOD80C package; 500 mW Ptot rating | Higher power margin but looser tolerance; identical footprint and mounting | Choose for legacy designs requiring drop-in replacement with relaxed regulation specs |
Compared with BZV55-B12,115, MMBZ5242B trades voltage accuracy for lower unit cost and wider availability, while BZX84-C12 retains mechanical compatibility but sacrifices 2.5× tighter tolerance - making the BZV55-B12,115 optimal for precision analog reference nodes where long-term stability and low drift are mandatory.

FAQ
What is the maximum continuous reverse current the BZV55-B12,115 can sustain?
The device supports a maximum continuous forward current of 250 mA per Absolute Maximum Ratings, but its Zener operation relies on controlled reverse current. At 12 V regulation, sustained reverse current must remain within total power limits: ≤33.3 mA for 400 mW at Tamb ≤ 50 °C, derated linearly above that ambient temperature.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a specified SZ range of −2.0 to +10.0 mV/K, the worst-case voltage drift is ±1.65 V over 165 K span - meaning regulation may shift from 10.35 V to 13.65 V. For high-accuracy systems, this requires compensation or operation within narrower temperature bands where drift stays below ±50 mV.
Can BZV55-B12,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient mismatch and unequal current sharing when paralleled. Even matched units will thermally runaway due to localized heating. For >400 mW dissipation, use a single higher-power Zener or active regulation instead.
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 SOD80C outline supports peak temperatures up to 260 °C for ≤30 seconds; recommended solder land dimensions are 1.70 mm × 2.25 mm with 2.30 mm pitch, per Figure 7 in the datasheet.
