Product details
Overview
D3Z3V0BF-7 from Diodes Incorporated is a 0.4W surface-mount precision Zener diode with nominal zener voltage of 3.0 V (2.85–3.07 V range), 95 Ω maximum zener impedance at 5 mA, and ±1.7 mV/°C temperature coefficient. It delivers stable voltage reference in low-power analog circuits, power supply feedback loops, and overvoltage protection for microcontroller I/O pins on FR-4 PCBs.
For engineers reviewing the D3Z3V0BF-7 datasheet, D3Z3V0BF-7 pinout, D3Z3V0BF-7 application, or D3Z3V0BF-7 equivalent, key selection criteria include tight VZ tolerance (±3.3%), low thermal resistance (312.5 °C/W), SOD323F package compatibility with automated assembly, and automotive-grade process capability per AEC-Q101 qualification readiness.
Technical Context
This Zener diode operates in reverse breakdown mode with precisely controlled VZ at IZT = 5 mA, exhibiting low dynamic impedance (95 Ω) and minimal voltage drift (−1.7 mV/°C). Its thermal design enables 400 mW dissipation on standard FR-4 layouts without forced cooling.
The device uses a planar epitaxial construction with cathode band marking, matte tin–annealed copper alloy leadframe, and halogen/antimony-free green molding compound rated UL 94V-0. Moisture sensitivity level is J-STD-020 Level 1.
Key Specifications

| Power Dissipation (PD) | 400 mW on FR-4 PCB - supports continuous operation in space-constrained consumer and industrial PCBs |
| Zener Impedance (ZZT) | ≤95 Ω at 1 kHz - maintains low output impedance for stable voltage reference under varying load |
| Temperature Coefficient | −1.7 mV/°C - minimizes drift across −65°C to +150°C operating range |
| Reverse Current (IR) | ≤10 μA at VR = 1 V - guarantees low leakage in high-impedance bias networks |
| Total Capacitance | 195 pF at VR = 0 V, 1 MHz - limits high-frequency noise coupling in signal conditioning paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C3V0,115 (Nexperia) | VZ = 2.94–3.06 V (±2%), ZZT = 90 Ω, PD = 300 mW, SOD323 package | Lower power rating reduces derating margin in thermally constrained layouts | Select when tighter VZ tolerance is prioritized over power headroom |
| MMSZ4684T1G (onsemi) | VZ = 2.85–3.15 V (±5.3%), ZZT = 130 Ω, PD = 500 mW, SOD123 package | Larger SOD123 footprint requires PCB redesign; higher ZZT degrades regulation under dynamic load | Choose only if legacy SOD123 layout reuse or higher PD is mandatory |
Compared with BZX384-C3V0 and MMSZ4684T1G, D3Z3V0BF-7 offers optimal balance of tight tolerance (±3.3%), low impedance (95 Ω), and SOD323F compatibility-making it preferred for new designs where board space, thermal performance, and reference accuracy are jointly critical.

FAQ
What is the maximum reverse current for D3Z3V0BF-7 at 1 V reverse bias?
The maximum reverse current (IR) is 10 µA at VR = 1 V and TA = 25°C. This low leakage ensures minimal loading on high-impedance bias networks and preserves accuracy in precision reference applications without requiring additional current-limiting resistors.
Can D3Z3V0BF-7 be used in automotive applications?
Yes-D3Z3V0BF-7 is manufactured in IATF 16949-certified facilities and qualifies for AEC-Q101 stress testing. While not pre-certified out-of-box, Diodes provides PPAP support and change control documentation required for automotive qualification upon request.
What is the thermal resistance junction-to-ambient for this Zener diode?
The typical thermal resistance (RθJA) is 312.5 °C/W when mounted on a standard FR-4 PCB (35 mm × 25 mm) with recommended pad layout. This value enables full 400 mW power dissipation at ambient temperatures up to +85°C without thermal derating.
Does D3Z3V0BF-7 have a cathode band marking?
Yes-the cathode is marked with a visible band on the SOD323F package body. This band aligns with the cathode terminal per JEDEC standards and must be oriented toward the higher-potential node in reverse-bias configurations to ensure proper Zener operation.
