Product details
Overview
DDZX6V2B-13 from Diodes Incorporated is a surface-mount precision Zener diode with nominal zener voltage 6.2 V (min 5.96 V, max 6.27 V), 300 mW power dissipation on FR-4 PCB, 7 Ω zener impedance at 20 mA test current, and 0.5 μA reverse leakage at 4.0 V. It is used for voltage regulation and reference in low-power analog circuits, including sensor biasing and ADC reference stabilization.
For engineers reviewing the DDZX6V2B-13 datasheet, DDZX6V2B-13 pinout, DDZX6V2B-13 application, or DDZX6V2B-13 equivalent, this page delivers verified electrical specs, SOT23 terminal mapping, automotive-grade reliability context (AEC-Q101 qualified), and real-world use cases - all grounded in Diodes Incorporated's DS30408 Rev. 13–2 datasheet.
Technical Context
This device operates as a two-terminal voltage reference, leveraging sharp zener breakdown at ~6.2 V with tight ±2% tolerance (5.96–6.27 V). Its low 7 Ω dynamic impedance at IZT = 20 mA ensures stable regulation under moderate load variation, while sub-μA leakage (<0.5 μA @ 4.0 V) minimizes error in high-impedance reference nodes.
Designed for automated SMT assembly, it features matte tin–annealed terminals, halogen/antimony-free "Green" molding compound (UL 94V-0), and moisture sensitivity level 1. Thermal resistance is 417 °C/W (junction-to-ambient, FR-4 PCB), requiring derating above +25 °C per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.96–6.27 V @ IZT = 20 mA - defines precise regulation band for feedback or reference use |
| Zener Impedance (ZZT) | 7 Ω @ 20 mA - low dynamic resistance enables stable output under varying current draw |
| Power Dissipation (PD) | 300 mW on FR-4 PCB - sets maximum continuous power before thermal derating applies |
| Reverse Leakage (IR) | 0.5 μA @ VR = 4.0 V - negligible current loss in high-Z reference paths |
| Operating Temperature | −65 to +150 °C - supports industrial and automotive under-hood environments |
| Thermal Resistance (RθJA) | 417 °C/W - dictates temperature rise per mW; requires layout-aware thermal design |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress-test standard, not just industrial grade |
Pinout & Package
Package: SOT23 - compact 3-pin surface-mount plastic case (0.915 mm width, 2.90 mm length), UL 94V-0 rated, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current sink during forward bias; connected to ground or lower potential in zener mode | Must be held at lower potential than cathode to enable reverse-biased regulation |
| Cathode (Pin 2) | Current source during zener conduction; connected to regulated voltage node | Provides stable 6.2 V reference when reverse-biased above breakdown threshold |
| No-Connect (Pin 3) | Internally unconnected terminal | Unused pad; must remain floating - no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp breakdown characteristics | Enables clean, predictable turn-on at 6.2 V without soft knee - critical for accurate reference generation |
| Tight VZ tolerance (±2%) | Reduces need for post-production trimming in precision analog designs |
| 300 mW dissipation on FR-4 | Supports direct integration into standard PCB layouts without heatsinking |
| AEC-Q101 qualification | Validates reliability for automotive applications including body control modules and sensor interfaces |
| Halogen- and antimony-free "Green" construction | Meets stringent environmental compliance (Br+Cl <1500 ppm, Sb <1000 ppm) for global OEM programs |
Applications
| Industrial Sensor Signal Conditioning | Automotive Cabin Temperature Sensor Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Nexperia) | Same 6.2 V nominal, but ±5% tolerance (6.2 V ±0.31 V); 400 mW PD; higher ZZT = 10 Ω | Acceptable where tighter regulation is not required; less suitable for high-accuracy ADC references | Select if cost sensitivity outweighs precision needs and higher power margin is beneficial |
| MMSZ5234B (ON Semiconductor) | 6.2 V nominal, ±5% tolerance; 500 mW PD; ZZT = 9 Ω; no AEC-Q101 qualification | Lacks automotive qualification; higher leakage (1.0 μA @ 4 V) reduces reference stability in low-power designs | Prefer only for non-automotive industrial use where extended temperature range is not mandatory |
Compared with BZX84-C6V2 and MMSZ5234B, DDZX6V2B-13 offers superior voltage accuracy (±2% vs. ±5%), lower dynamic impedance (7 Ω vs. ≥9 Ω), and certified AEC-Q101 reliability - making it the optimal choice for safety-critical or high-precision reference roles.

FAQ
What is the maximum zener test current (IZT) for DDZX6V2B-13?
The datasheet specifies IZT = 20 mA for VZ measurement and ZZT characterization. This is the recommended operating point for achieving specified 5.96–6.27 V regulation and 7 Ω impedance. Continuous operation beyond 20 mA requires thermal derating per Fig. 1, with absolute maximum power limited to 300 mW at +25 °C ambient.
Is DDZX6V2B-13 suitable for automotive applications?
Yes - DDZX6V2B-13 is explicitly qualified to AEC-Q101 standards for high-reliability automotive use. Its −65 to +150 °C operating range, halogen-free "Green" construction, and tested robustness against temperature cycling, humidity, and mechanical shock meet OEM requirements for under-hood and cabin electronics.
How does the SOT23 pinout differ between DDZX6V2B-13 and generic Zeners?
DDZX6V2B-13 uses standard SOT23 pinout: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = No-connect. Unlike some dual-diode or ESD variants, Pin 3 is internally unconnected - confirmed by Diodes Inc.'s package outline and schematic diagram. This eliminates risk of unintended shorting during layout or assembly.
What is the temperature coefficient of VZ for DDZX6V2B-13?
Per Fig. 16 in DS30408 Rev. 13–2, DDZX6V2B-13 exhibits a typical temperature coefficient of approximately +0.05 %/°C near 6.2 V. This positive TC means VZ increases slightly with temperature - a key factor when designing over-temperature compensation in precision reference circuits.
