Product details
Overview
D3Z13BF-7 from Diodes Incorporated is a 0.4W surface-mount precision Zener diode with nominal zener voltage 13.2V (min 12.91V, max 13.49V), ±1.8% tolerance at 5mA test current, 10Ω dynamic impedance at 5mA, and -9.4mV/°C temperature coefficient. It operates from -65°C to +150°C and delivers stable voltage reference in low-power analog monitoring circuits.
For engineers reviewing the D3Z13BF-7 datasheet, D3Z13BF-7 pinout, D3Z13BF-7 application, or D3Z13BF-7 equivalent, this part serves as a high-stability, low-capacitance (33pF) voltage reference for power supply feedback, overvoltage protection clamping, and sensor biasing where tight VZ tolerance and low thermal drift are critical.
Technical Context
This Zener diode uses silicon planar epitaxial construction to achieve precise breakdown characteristics with minimal hysteresis and low noise. Its SOD323F package enables automated placement while maintaining thermal resistance of 312.5°C/W on FR-4 PCBs.
The device exhibits 0.9V forward voltage at 10mA, reverse leakage ≤0.1μA at 10V, and total capacitance of 33pF at 0V - enabling use in both DC regulation and moderate-frequency transient suppression without signal distortion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13-7-F | 13V nominal, ±5% tolerance, 90Ω ZZT, 300mW rating, SOT-23 package | Higher impedance and looser tolerance reduce regulation accuracy in feedback loops | Select when cost sensitivity outweighs precision requirements and board space permits larger SOT-23 footprint |
| MMSZ5242B-7-F | 13V nominal, ±5% tolerance, 30Ω ZZT, 500mW rating, SOD-123 package | Larger package increases thermal mass but reduces power density; higher leakage (0.1μA vs 0.1μA) | Prefer for high-reliability industrial systems requiring extended lifetime under sustained 125°C ambient |
Compared with BZX84-C13-7-F and MMSZ5242B-7-F, D3Z13BF-7 delivers tighter voltage tolerance, lower dynamic impedance, and smaller footprint - making it optimal for space-constrained, high-accuracy analog subsystems where thermal performance and long-term stability are prioritized.

FAQ
What is the maximum continuous reverse voltage that D3Z13BF-7 can sustain without degradation?
D3Z13BF-7 is rated for continuous operation at its nominal zener voltage of 13.2V with full 400mW dissipation on FR-4 PCB. Sustained reverse voltage above 13.49V may cause thermal runaway unless current is strictly limited to maintain junction temperature below 150°C. Derating curves in DS35437 Rev. 10-2 confirm safe operation up to 13.5V at 25°C ambient.
Does D3Z13BF-7 meet AEC-Q200 stress testing requirements for automotive use?
No - D3Z13BF-7 is not AEC-Q200 qualified. While manufactured in IATF 16949-certified facilities and RoHS-compliant, it lacks formal qualification for automotive-grade temperature cycling, humidity bias, or mechanical shock testing. For AEC-Q200 applications, Diodes recommends the automotive-grade D3Z13BFQ-7 variant with PPAP documentation.
How does the -9.4mV/°C temperature coefficient affect circuit performance at 105°C ambient?
At 105°C ambient, the zener voltage shifts by approximately -0.79V from its 25°C value (ΔT = 80°C × -9.4mV/°C), resulting in VZ ≈ 12.41V. This shift is fully characterized in DS35437 and remains linear within specification - enabling accurate compensation in closed-loop systems using known thermal gradients.
Can D3Z13BF-7 be used in series to generate higher reference voltages?
Yes - two D3Z13BF-7 devices in series yield ~26.4V with doubled dynamic impedance (20Ω) and additive temperature coefficients (-18.8mV/°C). However, mismatched unit-to-unit VZ tolerance (±1.8%) results in worst-case stack error of ±3.6%, requiring post-calibration or trimming in precision applications.
