Product details
Overview
D3Z5V1BF-7 from Diodes Incorporated is a 0.4W surface-mount precision Zener diode with nominal zener voltage 5.1 V (4.96–5.20 V), ±2% tolerance, 60 Ω dynamic impedance at 5 mA, and −0.3 mV/°C temperature coefficient - used for voltage reference and regulation in low-power analog sensor interfaces and power supply feedback loops.
For engineers reviewing the D3Z5V1BF-7 datasheet, D3Z5V1BF-7 pinout, D3Z5V1BF-7 application, or D3Z5V1BF-7 equivalent, this page delivers verified electrical specs, SOD323F package details, thermal derating behavior, cathode-band polarity confirmation, and automotive-grade availability context - all critical for stable 5 V reference design in space-constrained PCBs.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage under varying load and temperature conditions. Its tight 5.1 V tolerance (±2%), low 60 Ω zener impedance at 5 mA test current, and negative temperature coefficient (−0.3 mV/°C) enable stable reference generation in analog front-ends and feedback networks.
Designed for FR-4 PCB mounting with 400 mW power dissipation capability and 312.5 °C/W junction-to-ambient thermal resistance, it supports operation from −65 °C to +150 °C and exhibits 145 pF capacitance at 0 V reverse bias - suitable for low-frequency regulation, not RF bypass.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.96–5.20 V @ IZT = 5 mA - defines regulated output range for 5 V reference circuits |
| Power Dissipation | 400 mW on FR-4 PCB - sets maximum continuous power before thermal derating applies |
| Zener Impedance | 60 Ω @ 1 kHz, IZT = 5 mA - determines output voltage stability under load variation |
| Temperature Coefficient | −0.3 mV/°C - quantifies voltage drift per degree Celsius; enables compensation modeling |
| Reverse Leakage | 2 μA @ VR = 1.5 V - ensures minimal error current in high-impedance reference nodes |
| Total Capacitance | 145 pF @ 0 V, 1 MHz - limits usable frequency range; unsuitable for >100 kHz noise filtering |
| Forward Voltage | 0.9 V @ IF = 10 mA - relevant only for forward-bias protection or dual-use configurations |
Pinout & Package
Package: SOD323F - ultra-small plastic surface-mount package (1.25 mm × 1.70 mm × 0.95 mm), moisture sensitivity level 1, matte tin-plated copper alloy leadframe, cathode band marking on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to lower-potential node in Zener regulation | Accepts current flow when forward-biased; tied to ground or common return in shunt regulator |
| Cathode | Negative terminal in forward bias; higher-potential node in Zener regulation | Connected to regulated output node; marked by visible band; carries reverse current during breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Precision voltage regulation | ±2% VZ tolerance enables <10 mV absolute error in 5 V reference designs |
| Automated assembly compatibility | SOD323F footprint and lead-free finish support high-yield reflow soldering without tombstoning |
| Thermal stability | −0.3 mV/°C TC allows predictable drift compensation in industrial temperature ranges |
| Low leakage performance | 2 μA max reverse current at 1.5 V ensures <1 μA error contribution in 1 MΩ bias networks |
| Green material compliance | Halogen- and antimony-free molding compound meets IPC-1752A Class 3 environmental requirements |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V1,115 (Nexperia) | Same 5.1 V nominal, ±2% tolerance, but 300 mW rating and 90 Ω ZZT | Higher impedance reduces regulation accuracy under dynamic load; lower power rating limits headroom | Select if cost-sensitive and thermal margin >100 mW is available; verify derating at 85 °C ambient |
| MMSZ5231B-TP (Micro Commercial Components) | 5.1 V, ±5% tolerance, 500 mW rating, 17 Ω ZZT, SOD-123 package | Looser tolerance increases reference uncertainty; lower impedance improves load regulation but larger footprint | Prefer for high-current shunt use where 5% VZ error is acceptable and board area permits SOD-123 |
Compared with BZX384-B5V1 and MMSZ5231B, D3Z5V1BF-7 offers superior voltage precision and thermal stability in the smallest footprint, making it optimal for compact, high-accuracy 5 V references where space and drift matter most.

FAQ
What is the maximum continuous power dissipation for D3Z5V1BF-7 on a standard FR-4 PCB?
D3Z5V1BF-7 is rated for 400 mW continuous power dissipation when mounted on a standard FR-4 PCB (35 mm × 25 mm) with the recommended pad layout. Derating begins above +25 °C ambient, reaching zero power at +150 °C per the published derating curve (Figure 1).
Does D3Z5V1BF-7 meet AEC-Q200 stress testing requirements for passive components?
No - D3Z5V1BF-7 is not AEC-Q200 qualified. While Diodes offers AEC-Q200-compliant Zeners (e.g., D3Z5V1BQ series), this part is intended for industrial and commercial applications. Automotive use requires explicit qualification confirmation and PPAP documentation from Diodes.
How is polarity identified on the SOD323F package of D3Z5V1BF-7?
Polarity is indicated by a visible cathode band on the top surface of the SOD323F package. The banded end corresponds to the cathode terminal; the opposite end is the anode. This matches the standard SOD323F mechanical drawing and is confirmed in the "Terminal Connections" section of DS35437 Rev. 10-2.
Can D3Z5V1BF-7 be used in place of a 5.0 V Zener diode in existing designs?
Yes - its 4.96–5.20 V range centers at 5.1 V and overlaps typical 5.0 V Zener tolerances. However, verify that the −0.3 mV/°C temperature coefficient and 60 Ω impedance meet system-level drift and regulation requirements, especially under varying thermal loads.
