Product details
Overview
BZX84C2V4Q-13-F from Diodes Incorporated is a 2.4 V, 350 mW surface-mount Zener diode in SOT23 package, designed for precision voltage regulation and reference applications at low current (5 mA test condition), with ±0.2 V tolerance, 100 Ω dynamic impedance at 5 mA, and -3.5 mV/°C temperature coefficient. It serves as a stable shunt voltage reference in power supply feedback loops and sensor biasing circuits.
For engineers reviewing the BZX84C2V4Q-13-F datasheet, BZX84C2V4Q-13-F pinout, BZX84C2V4Q-13-F application, or BZX84C2V4Q-13-F equivalent, key selection criteria include nominal Zener voltage (2.4 V), power rating (350 mW), thermal resistance (357 °C/W), reverse leakage (50 µA at 1.0 V), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 2.4 V reference across varying load currents, with specified test current of 5.0 mA and knee current of 1.0 mA. Its planar die construction ensures consistent voltage regulation and low noise performance under DC and low-frequency conditions.
The device exhibits a negative temperature coefficient of -3.5 mV/°C, enabling predictable drift compensation in temperature-sensitive references. Its SOT23 package supports automated assembly and delivers thermal resistance of 357 °C/W when terminals are held at ambient temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Same 2.4 V nominal, but 225 mW rating and 150 Ω ZZT; not AEC-Q101 qualified | Limited to commercial-grade consumer power supplies; unsuitable for under-hood automotive use | Select when cost is prioritized over automotive qualification and thermal margin |
| BZX84-C2V4,115 | NXP variant with identical electrical specs but different marking and packaging (7000/reel); same SOT23-3 package | Drop-in replacement in existing NXP-design schematics; same thermal and electrical behavior | Choose for legacy NXP BOM continuity or dual-sourcing flexibility |
Compared with MMBZ5221BS-7-F and BZX84-C2V4,115, the BZX84C2V4Q-13-F provides higher power headroom (350 mW vs. 225 mW), lower dynamic impedance (100 Ω vs. 150 Ω), and formal AEC-Q101 certification-making it optimal for thermally constrained or safety-critical automotive subsystems.

FAQ
What is the maximum reverse voltage (VR) this Zener diode can withstand before breakdown?
The BZX84C2V4Q-13-F has a nominal Zener voltage of 2.4 V, with breakdown occurring between 2.2 V and 2.6 V at 5 mA test current. Its maximum reverse voltage before significant conduction is defined by its rated Zener voltage range-not a separate VR parameter. At 1.0 V reverse bias, leakage is limited to 50 µA, confirming non-breakdown operation below 2.2 V.
Is this part suitable for use in high-frequency signal clamping applications?
No-this device is optimized for DC and low-frequency voltage reference use, not RF clamping. Its typical total capacitance is not specified for 2.4 V grade in the datasheet, and its 100 Ω dynamic impedance reflects low-speed regulation behavior. For signal clamping above 1 MHz, TVS diodes or fast-switching Schottky devices are recommended instead.
How does the -3.5 mV/°C temperature coefficient affect circuit accuracy over temperature?
Over a -40°C to +125°C range (165°C span), the Zener voltage shifts by approximately -578 mV, resulting in a 23.7% relative change from 2.4 V. In practice, this drift is mitigated by using the diode in compensated topologies (e.g., with positive-TC components) or limiting operating temperature range to ±25°C for ≤±0.1 V absolute error.
Does the "Q" suffix indicate AEC-Q101 qualification, and is it reflected in the device marking?
Yes-the "Q" in BZX84C2V4Q-13-F explicitly denotes AEC-Q101 qualification per Diodes Incorporated's ordering nomenclature. Devices are marked with "ZB" (Zener code) and date code; AEC-Q101 compliance is verified through internal qualification reports-not visible in top-side marking-but confirmed in packaging labels and Certificates of Conformance provided with shipments.
