Product details
Overview
BZX84C3V3Q-13-F from Diodes Incorporated is a 3.3 V, 5 mA nominal Zener voltage regulator diode in SOT23 package, rated for 350 mW power dissipation at ambient temperature, with 95 Ω maximum Zener impedance at test current and ±3.5 mV/°C temperature coefficient - used for precision voltage reference and overvoltage protection in low-power analog sensor interfaces.
For engineers reviewing the BZX84C3V3Q-13-F datasheet, BZX84C3V3Q-13-F pinout, BZX84C3V3Q-13-F application, or BZX84C3V3Q-13-F equivalent, key selection criteria include Zener voltage tolerance (±0.2 V), low reverse leakage (5.0 µA @ 1.0 V), thermal resistance (357 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 3.3 V regulation across load and line variations. It features planar die construction and matte tin–plated alloy 42 leadframe for solderability and RoHS compliance.
Designed for surface-mount automated assembly, it delivers consistent regulation under 5 mA test current with 1.0 mA knee current and 600 Ω maximum dynamic impedance below knee - enabling use in low-current biasing and reference circuits where thermal stability and repeatability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.3 V nominal, 3.1–3.5 V range at 5 mA - ensures tight regulation for 3.3 V rail monitoring and ADC reference stabilization |
| Power Dissipation | 350 mW at TA = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Zener Impedance | 95 Ω max at 5 mA, 600 Ω max at 1 mA - defines voltage deviation under varying load current in feedback or clamp circuits |
| Reverse Leakage | 5.0 µA max at 1.0 V - minimizes quiescent current in battery-powered voltage detection nodes |
| Temperature Coefficient | −3.5 mV/°C - enables predictable drift compensation in temperature-sensitive analog front-ends |
| Package | SOT23 - 3-pin surface-mount footprint compatible with standard pick-and-place and reflow processes |
Pinout & Package
Package: SOT23 - molded plastic case, UL 94V-0 flammability rating, 0.008 g weight, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4675-7-F | Same 3.3 V nominal Zener, but 500 mW rating and 300 Ω ZZT - higher power handling, looser impedance spec | Preferred in higher-current clamp circuits (>10 mA), less suitable for precision reference due to wider VZ tolerance (±5%) | Select when thermal margin >100 mW is required and voltage stability <±1% is not critical |
| BZX84-C3V3-7-F | Identical electrical specs, but standard (non-automotive) qualification and 3,000/reel packaging | Approved for industrial/commercial use only; lacks AEC-Q101 validation for automotive deployment | Choose for cost-sensitive non-automotive designs where qualification traceability is not mandated |
Compared with MMSZ4675-7-F and BZX84-C3V3-7-F, BZX84C3V3Q-13-F uniquely combines AEC-Q101 qualification, 10,000/reel tape-and-reel packaging, and tight 3.1–3.5 V Zener tolerance - making it optimal for high-volume automotive electronics requiring both reliability assurance and procurement scalability.

FAQ
What is the maximum Zener current for continuous operation?
The absolute maximum DC Zener current is derived from the 350 mW power rating and 3.3 V nominal voltage, yielding ~106 mA. However, thermal derating applies above 25°C ambient: at 85°C, power dissipation drops to ~210 mW, limiting practical continuous current to ~64 mA. Operation beyond this requires heatsinking or pulsed duty cycling.
Is BZX84C3V3Q-13-F suitable for ESD protection?
No - this device is not designed or characterized for ESD clamping. Its 350 mW rating and 600 Ω dynamic impedance are optimized for steady-state regulation, not nanosecond-scale transient absorption. For IEC 61000-4-2 ESD protection, use dedicated TVS diodes such as D3V3M1U2LP or PESD5V0S1BA.
How does the "Q" suffix affect the part's specifications?
The "Q" denotes AEC-Q101 qualification - meaning the device has passed stress tests for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing specific to automotive reliability standards. Electrical parameters remain identical to non-Q versions, but lot traceability and process controls meet automotive PPAP requirements.
Can this Zener be used in forward-bias applications?
Yes - as a standard silicon diode, it exhibits ~0.9 V forward voltage at 10 mA, per datasheet. However, its forward characteristics are not characterized for switching or rectification; it lacks specified reverse recovery time or surge current rating, so use is limited to low-speed, low-current biasing roles like LED current setting or logic-level translation.
