Product details
Overview
BZX84C6V8Q-13-F from Diodes Incorporated is an automotive-grade 6.8V, 350mW surface-mount Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in low-power analog and digital circuits. It delivers a nominal Zener voltage of 6.8V at 5mA test current, with ±0.4V tolerance (6.4–7.2V), 15Ω dynamic impedance at 5mA, and 2µA maximum reverse leakage at 4V.
For engineers reviewing the BZX84C6V8Q-13-F datasheet, BZX84C6V8Q-13-F pinout, BZX84C6V8Q-13-F application, or BZX84C6V8Q-13-F equivalent, this part supports stable reference generation in automotive body control modules, industrial sensor signal conditioning, and power supply feedback loops where AEC-Q101 qualification, tight voltage tolerance, and thermal reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its planar die construction ensures consistent parametric performance and high reliability in automated SMT assembly.
Rated for 350mW power dissipation at ambient temperature with RθJA = 357°C/W, it supports operation from –65°C to +150°C and exhibits a positive temperature coefficient of +1.2mV/°C near 6.8V, enabling predictable drift behavior in temperature-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8V nominal at IZT = 5mA; range 6.4–7.2V ensures reliable clamping in 5V–12V rail monitoring. |
| Power Dissipation | 350mW at TA = 25°C; derates linearly above 25°C per Fig. 1 - supports continuous operation in compact PCB layouts. |
| Zener Impedance (ZZT) | 15Ω at 5mA; low dynamic resistance minimizes output voltage variation under changing load currents. |
| Reverse Leakage (IR) | 2.0µA max at VR = 4.0V; ensures minimal quiescent current draw in battery-powered sensing nodes. |
| Temperature Coefficient | +1.2mV/°C at 6.8V; enables predictable voltage drift compensation in wide-temperature-range applications. |
| Package | SOT23 - 3-pin surface-mount package with 2.4mm × 1.3mm footprint; compatible with standard reflow profiles and AOI inspection. |
Pinout & Package
Package: SOT23 - molded plastic case, UL 94V-0 rated, matte tin-plated alloy 42 leadframe, polarity indicated by cathode band on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower-potential node in reverse-biased Zener configuration; carries full load current during regulation. |
| Cathode (Pin 2) | Zener breakdown terminal | Connected to higher-potential node; defines regulated output voltage referenced to anode potential. |
| NC / Dummy (Pin 3) | Non-connected internal tie | Internally unconnected; electrically isolated - must not be used as thermal pad or ground connection. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687T1G | 6.8V nominal, 500mW rating, SOD-123 package, ZZT = 10Ω at 5mA, IR = 1µA at 4V | Higher power rating and lower impedance suit higher-current regulation; larger SOD-123 footprint requires PCB redesign. | Select when >350mW dissipation or <15Ω ZZT is required; avoid if space-constrained or AEC-Q101 mandatory. |
| BZX84-C6V8-7-F | Identical electrical specs, same SOT23 package, but standard (non-automotive) qualification and 3,000-piece tape-and-reel packaging | Lacks AEC-Q101 validation; suitable only for commercial/industrial use where automotive reliability is not mandated. | Choose for cost-sensitive non-automotive designs with identical performance needs and no temperature or lifetime certification requirements. |
Compared with MMSZ4687T1G and BZX84-C6V8-7-F, BZX84C6V8Q-13-F uniquely balances AEC-Q101 compliance, 10,000-piece reel availability, and optimized thermal resistance (357°C/W) - making it the preferred choice for volume automotive production where traceability, qualification, and supply continuity are critical.

FAQ
What is the maximum Zener test current for BZX84C6V8Q-13-F?
The specified Zener test current (IZT) is 5.0mA, at which the nominal 6.8V Zener voltage is guaranteed within 6.4–7.2V. This current level is used for parameter characterization and ensures stable regulation under typical low-power reference conditions.
Is BZX84C6V8Q-13-F suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias voltage regulation. For bidirectional ESD protection, TVS diodes such as D24Z5.6M2L or PESD5V0S1BA are recommended, as they feature symmetrical clamping in both polarities.
Does the "Q" in BZX84C6V8Q-13-F indicate AEC-Q101 qualification?
Yes - the "Q" suffix denotes automotive qualification per AEC-Q101 standards. This includes stress testing for temperature cycling, high-temperature operating life, and electrostatic discharge robustness, confirming suitability for automotive electronic control units.
Can BZX84C6V8Q-13-F replace BZX84C6V8-7-F in existing designs?
Electrically yes - identical Zener voltage, impedance, and package - but the "Q" version adds AEC-Q101 qualification and uses green molding compound. Replacement requires validation of automotive reliability requirements and may necessitate requalification of the full assembly for automotive applications.
