Product details
Overview
DDZ9700-7 from Diodes Incorporated is a surface-mount low-current Zener diode with nominal zener voltage 13 V (min 12.35 V, max 13.65 V), rated for 500 mW power dissipation on FR-4 PCB at TL = +75°C, specified at 50 µA test current, and housed in SOD123 package. It serves as precision voltage reference or overvoltage clamp in portable battery-powered circuits, low-bias sensor interfaces, and power rail monitoring.
For engineers reviewing the DDZ9700-7 datasheet, DDZ9700-7 pinout, DDZ9700-7 application, or DDZ9700-7 equivalent, this part is selected for stable low-current regulation where thermal derating, reverse leakage (<0.05 µA @ 9.8 V), and tight zener voltage tolerance (±5%) are critical in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under controlled current conditions. Its 13 V nominal zener voltage exhibits a positive temperature coefficient (~0.06 %/°C per Fig. 18), optimized for mid-range voltage regulation where drift compensation is manageable without external circuitry.
The device uses an alloy-42 leadframe with matte tin annealed finish, enabling reliable solderability per MIL-STD-202 Method 208. Its SOD123 package delivers low thermal resistance (RθJL = 150 °C/W) and meets J-STD-020 moisture sensitivity Level 1, supporting standard reflow profiles without preconditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13-7-F | Same 13 V nominal, but rated 300 mW (vs. 500 mW); higher IR = 0.1 µA @ 9.8 V. | Limited to lower-power circuits; unsuitable for sustained 500 mW thermal loads on FR-4. | Select when board space is identical but power margin is >200 mW below requirement. |
| MMSZ5243B-7-F | 13 V nominal, 500 mW rating, but SOD-123 package with 0.1 µA IR @ 9.8 V and wider VZ tolerance (±5% vs. ±5% - same). | Higher leakage reduces accuracy in µA-biased references; otherwise functionally interchangeable. | Prefer for cost-sensitive non-battery designs where leakage impact is negligible. |
Compared with BZX84-C13-7-F and MMSZ5243B-7-F, DDZ9700-7 delivers superior leakage performance (0.05 µA) and verified 500 mW thermal capability on standard FR-4, making it optimal for long-life battery systems and industrial inputs requiring minimal drift.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9700-7 guarantees leakage ≤0.05 µA?
Per the Electrical Characteristics table, DDZ9700-7 guarantees IR ≤ 0.05 µA at VR = 9.8 V. This value is derived from the 75% rule applied to its 13 V nominal zener voltage (0.75 × 13 V = 9.75 V → rounded to 9.8 V), consistent with industry-standard Zener test methodology for leakage specification.
Can DDZ9700-7 be used in place of a 12 V Zener diode in a voltage reference circuit?
No - DDZ9700-7 has a nominal zener voltage of 13 V (range 12.35–13.65 V), not 12 V. Substituting it for a 12 V part would shift the reference point by ~8%, potentially violating ADC input range or comparator thresholds. Use DDZ9692 (6.8 V), DDZ9697 (10 V), or DDZ9699 (12 V) for 12 V-class regulation.
Is the SOD123 package of DDZ9700-7 compatible with IPC-7351B density levels?
Yes - Diodes' published SOD123 outline (DS30410 Rev. 17, page 7) specifies land pattern dimensions matching IPC-7351B "NOMINAL" density: pad width 0.6 mm, length 1.1 mm, spacing 1.4 mm. The recommended 1-inch² copper pad also satisfies IPC-2221 thermal relief guidelines for 500 mW operation.
Does DDZ9700-7 require derating when mounted on a 4-layer PCB with internal ground planes?
Yes - although RθJA is specified for FR-4 with minimum pad layout (340 °C/W), adding internal copper planes reduces thermal resistance. Derating should follow actual measured junction temperature; typical improvement is 20–30% lower RθJA, allowing up to ~650 mW at TL = +75°C, but design validation with thermal imaging is required before increasing power.
