Product details
Overview
DDZ6V2BS-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal zener voltage 6.2 V (5.96–6.27 V range), 20 mA test current, 7 Ω dynamic impedance at IZT, 0.5 µA max reverse leakage at 4.0 V, and 200 mW power dissipation in SOD323 package - used for voltage regulation and reference in low-power analog circuits, power supply feedback loops, and overvoltage protection.
For engineers reviewing the DDZ6V2BS-7 datasheet, DDZ6V2BS-7 pinout, DDZ6V2BS-7 application, or DDZ6V2BS-7 equivalent, this page delivers verified electrical specs, thermal derating behavior, SOD323 terminal mapping, real-world use cases in precision biasing and clamping, and validated alternative parts with documented parameter differences.
Technical Context
This Zener diode operates in reverse breakdown mode with sharp knee characteristics and tight ±2% VZ tolerance at 20 mA. Its low 7 Ω zener impedance ensures stable regulation under varying load currents, while 0.5 µA reverse leakage at 4.0 V supports high-impedance sensing nodes.
The device uses alloy 42 leadframe with matte tin annealed terminals, rated for -65°C to +150°C operation, and exhibits a temperature coefficient of approximately +0.04%/°C near 6.2 V - enabling predictable drift compensation in reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.96–6.27 V at IZT = 20 mA - defines regulated output voltage window under standard test conditions. |
| Zener Impedance (ZZT) | 7 Ω at IZT = 20 mA - low dynamic resistance enables minimal output voltage variation with load current changes. |
| Reverse Leakage (IR) | 0.5 µA max at VR = 4.0 V - ensures negligible current draw in standby or high-impedance bias networks. |
| Power Dissipation (PD) | 200 mW at TA = 25°C - sets maximum continuous power handling on FR-4 PCB with recommended pad layout. |
| Thermal Resistance (RθJA) | 625 °C/W - determines junction-to-ambient temperature rise per watt; requires derating above 25°C ambient. |
| Package | SOD323 - ultra-small 1.3 × 1.7 mm surface-mount outline with cathode band polarity marking. |
Pinout & Package
SOD323 package: 2-terminal surface-mount plastic case (UL 94V-0), 0.004 g weight, cathode marked by band. Terminals are matte tin annealed over alloy 42 leadframe, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side in reverse-bias regulation; forms reference ground return path. |
| Cathode | Zener breakdown terminal / regulated output node | Connected to higher-potential rail; supplies stable 6.2 V reference when reverse-biased above VZ. |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp breakdown knee | Enables precise voltage clamping with minimal transition region - critical for accurate overvoltage detection. |
| Tight VZ tolerance (±2%) | Reduces need for post-production trimming in voltage reference circuits - improves manufacturing yield. |
| Low leakage (0.5 µA @ 4 V) | Preserves signal integrity in high-impedance sensor biasing and battery-powered monitoring nodes. |
| Lead-free & halogen-free construction | Meets RoHS 2 and JEDEC MSL Level 1 requirements - supports automated reflow without moisture sensitivity concerns. |
Applications
| Power Supply Feedback | Precision Voltage Reference |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck converter feedback loop via optocoupler-coupled TL431 replacement. IC Role / Device Role / Timing Role: Zener diode provides stable 6.2 V reference to error amplifier input, setting output regulation threshold. Use Value: Tight VZ tolerance and low ZZT minimize output voltage drift across line/load/temperature variations. |
Use Scenario: Generating fixed bias point for op-amp input stages or ADC reference dividers in portable instrumentation. IC Role / Device Role / Timing Role: Acts as passive, low-power voltage reference node in resistor-divider networks feeding precision analog circuitry. Use Value: Sub-microamp leakage avoids loading high-impedance divider arms, preserving accuracy in <10 µA bias paths. |
| Overvoltage Clamp | ESD Protection Interface |
Use Scenario: Clamping transient surges on low-voltage I/O lines (e.g., 5 V logic rails) before they reach sensitive MCU pins. IC Role / Device Role / Timing Role: Zener conducts above 6.2 V to shunt excess energy to ground, limiting peak voltage seen by downstream components. Use Value: Sharp breakdown and 200 mW rating allow reliable clamping of short-duration transients without thermal runaway. |
Use Scenario: Supplementing TVS diodes on USB or UART lines where fast response and low capacitance are required. IC Role / Device Role / Timing Role: Provides secondary low-leakage clamping layer after primary ESD suppressor, reducing residual voltage overshoot. Use Value: 0.5 µA leakage at 4 V ensures no DC loading on communication lines; SOD323 footprint minimizes parasitic capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 (Nexperia) | VZ = 6.2 V ±5%, ZZT = 20 Ω @ 5 mA, PD = 300 mW, SOD523 package | Higher tolerance and impedance; larger power rating but smaller 1.2 × 0.8 mm package | Select when board space is constrained and ±5% VZ is acceptable; verify thermal margin with higher PD. |
| MMSZ5234B (ON Semiconductor) | VZ = 6.2 V ±5%, ZZT = 10 Ω @ 20 mA, PD = 350 mW, SOD123 package | Same VZ tolerance as BZX584 but lower impedance; larger SOD123 footprint and higher power | Choose for higher power handling and better thermal performance where PCB area permits SOD123 mounting. |
Compared with DDZ6V2BS-7, BZX584-C6V2 trades tighter VZ control for smaller size, while MMSZ5234B offers higher power and lower impedance at the cost of larger footprint - selection depends on board area, regulation accuracy, and thermal design constraints.

FAQ
What is the maximum reverse voltage (VR) that DDZ6V2BS-7 can block before breakdown?
DDZ6V2BS-7 begins controlled reverse breakdown at its specified zener voltage range of 5.96–6.27 V when tested at 20 mA. Below this threshold - specifically up to 4.0 V - it guarantees ≤0.5 µA reverse leakage. It is not rated for blocking voltages significantly above VZ; sustained operation above 6.27 V risks exceeding its 200 mW power limit unless current is strictly limited.
Can DDZ6V2BS-7 be used in place of a 6.2 V TL431 shunt regulator?
No - DDZ6V2BS-7 is a passive two-terminal Zener diode without internal amplification or adjustable reference capability. Unlike the TL431, it cannot sink variable current to maintain regulation across wide load ranges or provide programmable thresholds. It serves only as a fixed-voltage clamp or basic reference, not as an active error amplifier-based regulator.
How does the SOD323 package affect thermal performance compared to larger packages like SOD123?
The SOD323 package has higher thermal resistance (RθJA = 625 °C/W) than SOD123 (~300 °C/W), meaning it heats up faster under identical power dissipation. At 200 mW, junction temperature rise exceeds 125°C above ambient - requiring strict ambient limits or derating. Layout with copper pour and optimized pad geometry is essential to approach datasheet-rated performance.
Is DDZ6V2BS-7 suitable for automotive applications per AEC-Q200?
No - DDZ6V2BS-7 is not AEC-Q200 qualified. While its operating temperature range (-65°C to +150°C) overlaps with automotive requirements, Diodes Incorporated does not list this part in its AEC-Q200 stress-tested portfolio. For automotive use, consider the AEC-Q200 qualified BZX84-C6V2 or MMBZ5234ELT1G, which undergo extended reliability testing including temperature cycling and humidity bias.
