Product details
Overview
DDZ9692TQ-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 6.8 V (6.46–7.14 V range), 250 mW power dissipation, and 0.1 µA reverse leakage at 5.1 V, designed for precision voltage regulation in automotive power rail monitoring circuits.
For engineers reviewing the DDZ9692TQ-7 datasheet, DDZ9692TQ-7 pinout, DDZ9692TQ-7 application, or DDZ9692TQ-7 equivalent, key selection criteria include AEC-Q101 qualification, SOD523 package thermal resistance (500 °C/W), sharp breakdown characteristics, and low leakage performance under bias.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to clamp or regulate voltage at its specified nominal zener voltage of 6.8 V with tight tolerance (±5%). It exhibits very low reverse leakage current (0.1 µA @ VR = 5.1 V) and maintains stable regulation across -65°C to +150°C operating temperature range.
The device uses an alloy 42 leadframe with matte tin annealed terminals, qualified to AEC-Q101 for automotive reliability, and features a cathode band marking for unambiguous polarity identification in automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Zener Voltage Range | 6.46 V to 7.14 V - ±5% tolerance ensures predictable regulation window under production variation |
| Power Dissipation | 250 mW - limits maximum continuous power handling on FR-4 PCB with recommended pad layout |
| Reverse Leakage Current | 0.1 µA @ 5.1 V - enables ultra-low standby current in battery-backed or always-on circuits |
| Thermal Resistance θJA | 500 °C/W - defines junction-to-ambient temperature rise per watt dissipated on standard FR-4 board |
| Operating Temp Range | -65°C to +150°C - supports under-hood automotive environments and industrial control enclosures |
| AEC-Q101 Qualified | Yes - validated for high-reliability automotive applications including engine control and body electronics |

FAQ
What is the maximum zener test current (IZT) for DDZ9692TQ-7?
The datasheet specifies IZT = 50 µA for the DDZ9692TQ-7. This low test current enables accurate characterization of the zener knee region while minimizing self-heating effects, making it suitable for low-power reference and clamping applications where minimal bias current is critical.
Is DDZ9692TQ-7 compatible with lead-free reflow soldering processes?
Yes. DDZ9692TQ-7 uses matte tin-annealed terminals over alloy 42 leadframe and is fully RoHS 3 compliant. Its construction meets J-STD-020 moisture sensitivity level 1 and is rated for standard lead-free reflow profiles up to 260°C peak temperature without degradation.
How does the SOD523 package affect thermal performance?
The SOD523 package has a thermal resistance θJA of 500 °C/W on FR-4 PCB with recommended pad layout. Its small size limits heat spreading, so power dissipation must be kept below 250 mW at 25°C ambient; derating is required above 25°C per Figure 1 in the datasheet.
Can DDZ9692TQ-7 replace a 6.2 V Zener in an existing design?
No-DDZ9692TQ-7 has a nominal zener voltage of 6.8 V (6.46–7.14 V range). Substituting it for a 6.2 V part would raise the regulation/clamp threshold by ~10%, potentially causing functional failure in circuits relying on precise voltage thresholds, such as reset generators or overvoltage comparators.
