Product details
Overview
BZX84-C27/DG/B2,23 from Nexperia is a surface-mount 27 V Zener diode in SOT23 package, with nominal Zener voltage of 27 V ±5%, power dissipation of 300 mW, and maximum Zener impedance of 80 Ω at 1 mA, used for voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84-C27/DG/B2,23 datasheet, BZX84-C27/DG/B2,23 pinout, BZX84-C27/DG/B2,23 application, or BZX84-C27/DG/B2,23 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at test current, power derating curve, thermal resistance, and reverse leakage current at rated voltage.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across its terminals. It is characterized at IZ = 5 mA with VZ = 27 V, IZK = 1 mA minimum knee current, and exhibits VZ drift of ±0.07 %/°C typical temperature coefficient.
Designed for DC voltage clamping and precision biasing, it supports continuous operation up to 150 °C junction temperature and complies with AEC-Q101 for automotive-grade reliability when operated within specified derating limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±5% at IZ = 5 mA - defines regulated output voltage under nominal bias |
| Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling before thermal shutdown |
| Zener Impedance (ZZK) | 80 Ω max at IZ = 1 mA - determines voltage regulation sensitivity to load current changes |
| Reverse Leakage (IR) | 100 nA max at VR = 20.3 V - ensures minimal parasitic current in standby or high-impedance sensing nodes |
| Temperature Coefficient | ±0.07 %/°C typical - quantifies VZ drift per degree Celsius for stability-critical references |
| Junction Temperature | –65 °C to +150 °C - specifies operational thermal envelope for industrial and automotive environments |
Pinout & Package
Package: SOT23 - three-terminal plastic surface-mount package with standard lead pitch of 0.95 mm and footprint compatible with automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower-potential node during Zener operation; enables reverse-bias configuration |
| Cathode (Pin 2) | Reverse breakdown terminal | Connected to higher-potential node; carries regulated Zener current during clamping |
| NC / Dummy (Pin 3) | Non-connected internal tie | Internally unconnected; no electrical function - mechanical support only |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 80 Ω max at 1 mA - improves regulation accuracy under varying load conditions |
| AEC-Q101 qualified | Qualified for automotive applications - meets stress testing requirements for temperature cycling, HTRB, and ESD |
| Tight voltage tolerance | ±5% at 5 mA - reduces need for post-regulation trimming in production calibration |
| High surge capability | 3 A peak pulse current (tp = 100 µs) - withstands transient overvoltage events without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5256BS-7-F | 27 V ±5%, 350 mW Ptot, ZZK = 100 Ω max - higher power but higher impedance | Preferred where board space allows larger SOT323 footprint and higher thermal margin is needed | Select when ambient temperature exceeds 85 °C and derated power must exceed 220 mW |
| BZX84-C27,215 | Identical VZ and tolerance, same SOT23 package, but non-AEC-Q101 qualified | Suitable for commercial-grade consumer products where automotive qualification is not required | Choose for cost-sensitive non-automotive designs with identical electrical performance |
Compared with BZX84-C27/DG/B2,23, MMBZ5256BS-7-F offers higher power headroom but looser regulation; BZX84-C27,215 matches all electrical specs but lacks automotive qualification - selection depends on thermal environment and compliance requirements.

FAQ
What is the maximum reverse leakage current for BZX84-C27/DG/B2,23 at 20.3 V?
The maximum reverse leakage current is 100 nA at VR = 20.3 V and Tj = 25 °C, as specified in Nexperia's official datasheet Rev. 3.0. This value increases to 1 µA at 150 °C junction temperature, confirming suitability for high-temperature operation without excessive standby loss.
Is BZX84-C27/DG/B2,23 pin-compatible with other SOT23 Zener diodes?
Yes - it uses standard SOT23 pinout (Anode–Cathode–NC), matching industry layout for Zener diodes including BZX84-C24 through BZX84-C33 variants. Pin 1 is Anode, Pin 2 is Cathode, and Pin 3 is internally unconnected - verified by Nexperia package drawing SOT23-3.
Does this part support reflow soldering per JEDEC J-STD-020?
Yes - the SOT23 package is rated for peak reflow temperature of 260 °C for 30 seconds, compliant with JEDEC J-STD-020D. Thermal resistance Rthj-amb = 430 K/W confirms compatibility with standard PCB pad layouts using 25 mm² copper pour per terminal.
What is the Zener voltage tolerance at 5 mA test current?
The Zener voltage tolerance is ±5% at IZ = 5 mA, meaning the measured VZ falls between 25.65 V and 28.35 V under that condition. This tolerance is guaranteed across the full operating temperature range of –65 °C to +150 °C, per Nexperia's production test specification.
