Product details
Overview
DDZ5V1BSF-7 from Diodes Incorporated is a precision 5.1 V Zener diode in SOD323F package, designed for voltage regulation and reference applications with ±2.5% tolerance (4.94–5.20 V), 130 Ω dynamic impedance at 20 mA, and 7.5 µA reverse leakage at 2 V. It delivers stable regulation in low-power analog circuits, power supply feedback paths, and sensor biasing networks.
For engineers reviewing the DDZ5V1BSF-7 datasheet, DDZ5V1BSF-7 pinout, DDZ5V1BSF-7 application, or DDZ5V1BSF-7 equivalent, this part supports precision voltage clamping, overvoltage protection, and reference generation where tight VZ tolerance, low thermal resistance (250 °C/W), and AEC-Q200-ready manufacturing are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal test current of 20 mA and exhibits a temperature coefficient near 0 mV/°C at 5.1 V, minimizing drift across industrial temperature ranges (−65 to +150 °C). Its 500 mW power rating is specified on FR-4 PCB with 10 mm × 10 mm copper pad.
The SOD323F package features matte tin–annealed copper alloy leads, J-STD-020 Level 1 moisture sensitivity, and a cathode band marking. It is halogen- and antimony-free, fully RoHS 3 compliant, and manufactured in IATF 16949 certified facilities.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V1 (Nexperia) | 5.1 V ±5%, 90 Ω ZZT, SOD523 package, 300 mW rating | Lower power and smaller footprint; higher impedance tolerance impacts regulation fidelity | Select when board space is constrained and ±5% VZ is acceptable |
| MMSZ5231B (ON Semiconductor) | 5.1 V ±5%, 17 Ω ZZT, SOD123 package, 500 mW rating | Larger SOD123 footprint; significantly lower impedance improves transient response but increases layout area | Select when lowest possible ZZT is prioritized over miniaturization |
Compared with BZX584C5V1 and MMSZ5231B, DDZ5V1BSF-7 uniquely balances ±2.5% tolerance, 130 Ω impedance, and SOD323F size-making it optimal for space-constrained industrial references requiring tighter regulation than standard Zeners but without SOD123 layout penalties.

FAQ
What is the maximum steady-state power dissipation for DDZ5V1BSF-7 on a standard FR-4 PCB?
The DDZ5V1BSF-7 is rated for 500 mW power dissipation when mounted on an FR-4 PCB with a 10 mm × 10 mm copper pad on a 35 mm × 25 mm board. Derating begins above +25 °C ambient, following the curve in Figure 1 of DS31987 Rev. 23–2, reaching zero dissipation at +150 °C.
Does DDZ5V1BSF-7 meet AEC-Q200 requirements for passive components?
DDZ5V1BSF-7 is manufactured in IATF 16949 certified facilities and supports PPAP documentation. While not individually AEC-Q200 tested, its construction, material set (halogen/antimony-free, matte tin leads), and qualification pedigree align with AEC-Q200 stress test categories for Zener diodes used in automotive applications.
How is the cathode identified on the SOD323F package?
The cathode is marked by a visible band printed on the top surface of the SOD323F package, located adjacent to the cathode terminal. This matches the mechanical drawing in DS31987 page 5 and is consistent with industry-standard polarity marking for surface-mount Zener diodes.
What is the typical temperature coefficient of DDZ5V1BSF-7 near its operating point?
Per Figure 3 in DS31987 Rev. 23–2, the temperature coefficient of DDZ5V1BSF-7 is approximately 0 mV/°C at 5.1 V, indicating minimal VZ drift over temperature-critical for stable reference performance across −65 to +150 °C operating range.
