Product details
Overview
BZX84C5V1Q-13-F from Diodes Incorporated is a 5.1 V, 350 mW surface-mount Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in low-power analog circuits. It delivers ±5% nominal Zener voltage tolerance at 5 mA test current, exhibits 60 Ω dynamic impedance at IZT, and maintains stable operation across –65 °C to +150 °C ambient range. Used in automotive sensor signal conditioning and industrial power supply feedback paths.
For engineers reviewing the BZX84C5V1Q-13-F datasheet, BZX84C5V1Q-13-F pinout, BZX84C5V1Q-13-F application, or BZX84C5V1Q-13-F equivalent, key selection criteria include Zener voltage accuracy (4.8–5.4 V), low reverse leakage (<2 µA at 2 V), temperature coefficient (–2.7 mV/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to clamp or regulate voltage with minimal deviation under varying load and temperature conditions. Its planar die construction ensures repeatable breakdown characteristics and low thermal resistance (357 °C/W junction-to-ambient).
The device features a nominal 5.1 V Zener voltage at 5 mA test current, 480 Ω maximum knee impedance at 1 mA, and a negative temperature coefficient of –2.7 mV/°C - enabling predictable drift compensation in reference designs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5231B-TP (Micro Commercial) | Same 5.1 V nominal, but ±5% tolerance and 100 Ω ZZT; no AEC-Q101 qualification. | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial environments. | Select when cost sensitivity outweighs automotive qualification and tighter impedance requirements. |
| BZX84-C5V1,115 (Nexperia) | Identical 5.1 V rating and SOT23 package, but 70 Ω ZZT and –2.5 mV/°C TC; AEC-Q101 qualified. | Compatible in most automotive feedback loops, but slightly higher impedance may affect high-frequency ripple rejection. | Prefer for second-source flexibility where minor ZZT increase is acceptable and same qualification level is required. |
Compared with MMSZ5231B-TP and BZX84-C5V1,115, the BZX84C5V1Q-13-F offers the lowest Zener impedance (60 Ω) and tightest TC match (–2.7 mV/°C) among AEC-Q101-qualified 5.1 V Zeners, making it optimal for precision analog feedback where thermal stability and dynamic regulation error are critical.

FAQ
What is the maximum reverse voltage (VR) before significant leakage occurs?
The BZX84C5V1Q-13-F exhibits ≤2.0 µA reverse current at 2.0 V, per the datasheet's Electrical Characteristics table. At 4.0 V, leakage remains below 10 µA - well below the 5 mA Zener test current, confirming stable regulation onset near 4.8 V.
Is this part suitable for use in a 5 V LDO feedback network?
Yes - its 5.1 V nominal Zener voltage, ±5% tolerance, and low 60 Ω dynamic impedance make it appropriate for adjusting LDO output via resistor divider feedback, provided the cathode connects to the feedback node and anode to ground.
How does the "Q" suffix in BZX84C5V1Q-13-F affect specifications?
The "Q" denotes AEC-Q101 qualification - verified stress testing for automotive reliability, including HTOL, temperature cycling, and ESD. Electrical specs remain identical to non-Q variants; only qualification status and traceability differ.
Can this Zener diode replace a 5.0 V TL431-based shunt regulator?
No - the BZX84C5V1Q-13-F is a two-terminal passive Zener, lacking the adjustable reference, internal amplifier, and current-sink capability of the TL431. It provides fixed-voltage clamping only, not active regulation with programmable setpoints.
