Product details
Overview
DDZ6V2BQ-13 from Diodes Incorporated is a precision Zener diode in SOD123 package, designed for voltage regulation and reference applications in automotive and industrial circuits. It delivers a tightly controlled zener voltage of 5.96–6.27 V at 20 mA test current, with low dynamic impedance (7 Ω at 1 kHz), maximum reverse leakage of 0.5 µA at 4.0 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the DDZ6V2BQ-13 datasheet, DDZ6V2BQ-13 pinout, DDZ6V2BQ-13 application, or DDZ6V2BQ-13 equivalent, this device is selected for stable low-power voltage reference, overvoltage clamping, and analog signal conditioning where ±2.5% VZ tolerance, thermal stability, and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its cathode–anode terminals. Its design targets low-noise, low-temperature-coefficient performance in compact surface-mount layouts, with specified operation from –65°C to +150°C and power dissipation up to 470 mW at 25°C ambient.
The device uses alloy 42 leadframe with matte tin annealed finish, complies with J-STD-020 Level 1 moisture sensitivity, and features UL 94V-0 molded plastic packaging - all supporting automated reflow assembly and long-term reliability in harsh environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (ON Semiconductor) | Same 6.2 V nominal, but ±5% tolerance (6.0–6.4 V); 10 Ω ZZT; no AEC-Q101 rating | Limited to commercial-grade consumer or industrial non-automotive use | Select when cost sensitivity outweighs automotive qualification and tighter tolerance needs |
| MMSZ4687 (Vishay) | 6.2 V nominal, ±5% tolerance; 10 Ω ZZT; SOD-123 package; AEC-Q101 qualified | Matches automotive qualification but lacks tight 2.5% VZ tolerance | Choose when AEC-Q101 is mandatory but ±5% regulation tolerance is acceptable |
Compared with BZX84-C6V2 and MMSZ4687, DDZ6V2BQ-13 uniquely combines AEC-Q101 qualification, ±2.5% VZ tolerance, and 7 Ω impedance - making it optimal for automotive safety-critical references where both regulatory compliance and precision are non-negotiable.

FAQ
What is the maximum steady-state power dissipation for DDZ6V2BQ-13 at +75°C ambient?
The device supports 500 mW power dissipation at TL = +75°C (lead temperature), as defined in the Absolute Maximum Ratings table. This value assumes proper thermal coupling to the PCB and accounts for junction-to-lead thermal resistance of 132°C/W. Derating curves in Figure 1 confirm linear reduction to 470 mW at +25°C ambient.
Does DDZ6V2BQ-13 have a specified temperature coefficient for its zener voltage?
Yes - Figure 16 shows typical TC of VZ for 5.1–10 V devices, placing DDZ6V2BQ-13 near 0.03%/°C. While not explicitly tabulated, its position between DDZ5V6B and DDZ7V5B confirms a low, positive temperature coefficient ideal for stable mid-range voltage references.
Can DDZ6V2BQ-13 be used in place of a 6.2 V Zener with higher current capability?
No - its rated test current is 20 mA, and maximum DC current must remain within power limits (e.g., ≤75 mA at 6.2 V yields 465 mW). For higher-current applications, parallel configurations or higher-power packages like DO-214AC are required; SOD123 thermal limits preclude sustained >100 mA operation.
Is the SOD123 package of DDZ6V2BQ-13 compatible with standard reflow profiles?
Yes - the device is rated for moisture sensitivity Level 1 per J-STD-020 and supports standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C). Its matte tin annealed terminals meet MIL-STD-202 Method 208 solderability requirements, ensuring reliable wetting and joint integrity.
