Product details
Overview
BZX84-C10/DG/B3,23 from Nexperia is a 10 V ±5% Zener diode in SOT23 package, rated for 300 mW power dissipation and 5 mA test current, with 20 Ω dynamic impedance at 5 mA, used for voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84-C10/DG/B3,23 datasheet, BZX84-C10/DG/B3,23 pinout, BZX84-C10/DG/B3,23 application, or BZX84-C10/DG/B3,23 equivalent, key selection criteria include Zener voltage tolerance, power rating, dynamic impedance, temperature coefficient, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across varying load and supply conditions. It exhibits a nominal Zener voltage of 10 V at 5 mA test current, with a maximum dynamic impedance of 20 Ω and a temperature coefficient of +8.5 mV/K.
The device is optimized for low-current regulation and signal-level clamping, supporting operation from −65 °C to +150 °C ambient, and conforms to AEC-Q101 for automotive-grade reliability when qualified per specific lot traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% at IZ = 5 mA - defines precise clamping threshold for 9.5–10.5 V regulation range |
| Power Dissipation (Ptot) | 300 mW - limits continuous thermal load in SOT23 package without derating below 25 °C |
| Dynamic Impedance (ZZT) | 20 Ω max at IZ = 5 mA - determines output voltage stability under small-signal current variation |
| Test Current (IZT) | 5 mA - standard condition for specifying VZ and ZZT; design must ensure bias stays near this point for accuracy |
| Temperature Coefficient (TC) | +8.5 mV/K - quantifies VZ drift per degree Celsius rise, critical for temperature-sensitive references |
| Reverse Leakage (IR) | 100 nA max at VR = 7.6 V - ensures minimal parasitic current in standby or high-impedance nodes |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount, 3-terminal plastic case with standard pin assignment: Anode (Pin 1), Cathode (Pin 2), unused (Pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to lower-potential node; reverse-biased connection enables Zener conduction |
| Pin 2 | Cathode | Connected to higher-potential node; polarity marking aligns with cathode band on package |
| Pin 3 | No Connect | Internally unconnected; electrically isolated and may be left floating or grounded per layout |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables tight regulation without external trimming in cost-sensitive consumer and industrial supplies |
| AEC-Q101 qualified variants available | Supports automotive body electronics requiring validated reliability and failure rate data |
| SOT23 footprint compatibility | Allows drop-in replacement with other BZX84 series diodes and simplifies PCB reuse across voltage grades |
| Low leakage (≤100 nA) | Minimizes error in high-impedance reference dividers and battery-powered sensor bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BS-7-F | 10 V ±5%, 350 mW, SOT323 package, 17 Ω ZZT | Smaller footprint but lower thermal mass; requires tighter layout control for power handling | Select when board area is constrained and thermal margin allows 350 mW rating |

FAQ
What is the maximum reverse current before breakdown for BZX84-C10/DG/B3,23?
The device maintains ≤100 nA reverse leakage current up to 7.6 V applied reverse voltage. Breakdown begins near 9.5 V (lower limit of 10 V ±5%), with full Zener conduction established by 10 V at 5 mA test current per datasheet definition.
Can BZX84-C10/DG/B3,23 replace BZX84-C10,215 in production?
Yes-both share identical electrical specifications, thermal performance, and SOT23 mechanical dimensions. The only distinction is tape-and-reel packaging: BZX84-C10/DG/B3,23 uses 13" reels while BZX84-C10,215 uses 7" reels, affecting pick-and-place feeder compatibility only.
Is this Zener diode suitable for use in automotive infotainment power rails?
Yes, when sourced as AEC-Q101 qualified (e.g., part number BZX84-C10-Q), it meets automotive reliability requirements. Standard BZX84-C10/DG/B3,23 is not automatically qualified; qualification status must be verified per batch documentation and ordering code.
How does temperature affect the 10 V Zener voltage in practical operation?
Voltage drift is +8.5 mV/K above 25 °C ambient. At 125 °C junction temperature, VZ increases by ~0.85 V, resulting in ~10.85 V output. Designers must account for this in high-temperature reference paths or use TC-compensated configurations.
