Product details
Overview
BZV90-C12,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation in power supply feedback paths. It provides a nominal 12 V working voltage (11.4–12.7 V), ±5% tolerance, 10–25 Ω differential resistance at 5 mA test current, 1.5 W total power dissipation, and operates up to 150 °C junction temperature - used in industrial power adapters and embedded voltage monitoring circuits.
For engineers reviewing the BZV90-C12,115 datasheet, BZV90-C12,115 pinout, BZV90-C12,115 application, or BZV90-C12,115 equivalent, key selection criteria include Zener voltage accuracy at IZtest = 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power capability (40 W), and SOT223 thermal pad layout compatibility with FR4 PCB copper area ≥2 cm².
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its differential resistance (6–10 Ω typical at 5 mA) and low temperature coefficient (+6.0 mV/K max) ensure stable reference performance under varying load and ambient conditions.
The device uses a silicon planar epitaxial construction optimized for low noise and repeatable breakdown characteristics. Its SOT223 package integrates a large collector pad (Pin 3) for enhanced thermal conduction, enabling reliable operation at 1.5 W continuous dissipation when mounted on double-sided FR4 with 2 cm² copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage VZ | 11.4–12.7 V at IZtest = 5 mA - defines regulated output voltage window for feedback loop design |
| Differential Resistance rdif | 10–25 Ω at IZtest = 5 mA - determines output impedance and load regulation error |
| Temp. Coefficient SZ | +6.0 mV/K max - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation Ptot | 1500 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 μs - supports surge suppression in transient overvoltage protection stages |
| Junction Temperature Tj | −65 to +150 °C - enables use in extended-temperature industrial environments without derating |
| Reverse Current IR | ≤0.1 μA at VR = 9.4 V - ensures minimal leakage in high-impedance bias networks |
Pinout & Package
SOT223 plastic surface-mounted package with integrated thermal pad (Pin 3). Dimensions: 6.7 × 3.7 × 1.8 mm (L × W × H); lead pitch 4.6 mm; copper-clad PCB mounting required for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main forward current entry point; connected to lower-potential node in Zener configuration |
| 2, 4 | Cathode | Common cathode terminals - tied together electrically; connect to regulated output/reference node |
| 3 | Thermal Pad / Collector | Exposed copper pad for heat sinking; must be soldered to ≥2 cm² PCB copper area for rated Ptot |
Key Features
| Feature | Design Value |
|---|---|
| ±5% voltage tolerance (E24 series) | Enables direct replacement across 37 standard Zener values without custom calibration |
| 1.5 W continuous power rating | Supports higher-current regulation than SOD-123 or DO-35 devices, reducing need for external pass transistors |
| Low differential resistance (6–10 Ω typ.) | Minimizes output voltage variation under ±10% load current changes in feedback networks |
| 83.3 K/W thermal resistance (j-a) | Allows full 1.5 W operation with ≤125 °C junction rise above 25 °C ambient on standard PCB layout |
| Non-repetitive 40 W surge rating | Withstands brief line transients (e.g., IEC 61000-4-5 Level 3) without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZX84-C12LT1G | Same 12 V nominal Zener voltage, but SOT-23 package (0.35 W Ptot), higher rdif (30 Ω), no thermal pad | Limited to low-power signal-level regulation; unsuitable for >100 mA load currents or surge suppression | Select only when board space is constrained and thermal budget allows significant derating |
| Vishay BZX84-B12-7-F | 12 V Zener, ±2% tolerance, SOT-23, 350 mW Ptot, rdif = 25 Ω, tighter tolerance but lower power | Better voltage accuracy but cannot sustain continuous 1.5 W or 40 W surges - requires external heatsinking for equivalent power | Choose when ±2% initial accuracy outweighs thermal performance requirements |
Compared with BZX84-C12LT1G and BZX84-B12-7-F, the BZV90-C12,115 delivers 4.3× higher continuous power and integrated thermal management - making it the only option among the three capable of standalone 12 V regulation in industrial power supplies without auxiliary cooling.

FAQ
What is the recommended PCB layout for optimal thermal performance of BZV90-C12,115?
Mount the device on FR4 with double-sided 2 cm² copper area connected directly to Pin 3 (thermal pad). Use ≥4 thermal vias (0.3 mm diameter) under the pad to inner ground plane. Avoid narrow traces on anode/cathode connections to minimize IR drop during surge events.
Does BZV90-C12,115 meet AEC-Q101 for automotive applications?
No - the BZV90-C12,115 is not AEC-Q101 qualified. It is rated for industrial temperature range (−65 to +150 °C) and used in automotive body control modules where qualification is not mandated, but not for engine bay or safety-critical systems requiring formal AEC certification.
Can BZV90-C12,115 replace older Philips BA120 Zener diodes?
Yes - the BZV90-C12,115 is the direct Nexperia successor to the Philips BA120, sharing identical SOT223 footprint, electrical specs (12 V, 1.5 W), and thermal characteristics. The part number change reflects Nexperia's rebranding after the 2017 spin-off; no design modifications are needed.
What is the maximum allowable reverse voltage before breakdown onset?
The guaranteed maximum reverse voltage before breakdown is 9.4 V (VR) at IR = 0.1 μA. Below this, leakage remains ≤0.1 μA - critical for maintaining accuracy in high-impedance bias networks where even nanoampere leakage affects settling time.
