Diodes Incorporated DDZ9696Q-7

Overview

DDZ9696Q-7 from Diodes Incorporated is a surface-mount, low-current Zener diode in SOD123 package, rated for 9.1 V nominal zener voltage (±5% tolerance), 500 mW power dissipation at TL = +75°C on FR-4 PCB, and specified at 50 µA test current - optimized for low-bias, battery-powered voltage reference and regulation in portable electronics.

For engineers reviewing the DDZ9696Q-7 datasheet, DDZ9696Q-7 pinout, DDZ9696Q-7 application, or DDZ9696Q-7 equivalent, this AEC-Q101 qualified automotive-grade Zener provides stable reverse breakdown with low leakage (≤0.1 µA @ 6.9 V), tight voltage tolerance, and thermal stability critical for precision biasing, overvoltage clamping, and voltage monitoring in space-constrained designs.

Technical Context

This device operates as a two-terminal, silicon planar Zener diode with controlled avalanche breakdown at 9.1 V. Its low 50 µA test current enables accurate regulation under micro-power conditions, while its negative temperature coefficient (≈−0.02 %/°C near 9.1 V, per Fig. 17) ensures predictable drift behavior across −65°C to +150°C operating range.

The SOD123 package delivers 150 °C/W junction-to-lead thermal resistance and supports automated assembly with matte tin–annealed terminals solderable per MIL-STD-202. It exhibits ≤15 pF total capacitance at 1 MHz and VR = 1 V, making it suitable for low-frequency reference and DC stabilization-not RF or high-speed signal applications.

FAQ

What is the maximum reverse voltage before breakdown for DDZ9696Q-7?

The nominal zener voltage is 9.1 V with a tolerance of ±5%, meaning breakdown occurs between 8.65 V and 9.56 V at I_ZT = 50 µA. Below 6.9 V reverse bias, leakage remains ≤0.1 µA - no hard "maximum" non-breakdown voltage is specified, but operation below 6.9 V ensures negligible conduction.

Is DDZ9696Q-7 compatible with lead-free reflow profiles?

Yes - it features matte tin–annealed terminals fully compliant with Pb-free soldering per JEDEC J-STD-020, supporting peak reflow temperatures up to 260°C (Level 1 moisture sensitivity). The SOD123 package is qualified for standard SnAgCu profiles without preconditioning.

Does DDZ9696Q-7 have a specified zener impedance?

No exact zener impedance (Z_ZT) value is tabulated in DS30410, but Fig. 12 shows typical dynamic impedance ≈150 Ω at I_Z = 1 mA and V_Z ≈9.1 V. At the rated 50 µA test current, impedance rises significantly - design for regulation should assume >1 kΩ unless measured under actual bias conditions.

Can DDZ9696Q-7 replace a 9.1 V Zener in a linear regulator feedback network?

Yes - its 50 µA test current and tight 5% tolerance make it well-suited for shunt regulator feedback paths, provided the external resistor supplies ≥50 µA while maintaining sufficient headroom above 9.1 V. Verify thermal rise under worst-case load, as P_D derates linearly above +75°C.
