Product details
Overview
BZX84C3V0-7-F from Diodes Incorporated is a 3.0 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 BZX84C3V0-7-F datasheet, BZX84C3V0-7-F pinout, BZX84C3V0-7-F application, or BZX84C3V0-7-F equivalent, key selection criteria include Zener voltage tolerance (±0.2 V), low reverse leakage (10 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 to maintain stable 3.0 V regulation across 1.0–5.0 mA current range, with tight 2.8–3.2 V min/max voltage spread at 5 mA test current. Its planar die construction ensures consistent breakdown characteristics and low dynamic impedance.
The device exhibits a negative temperature coefficient of −3.5 mV/°C, enabling predictable drift compensation in temperature-sensitive references. It is optimized for surface-mount automated assembly and meets halogen- and antimony-free "Green" requirements per Diodes Incorporated 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 |
|---|---|---|---|
| MMBZ5223BS-7-F | 3.0 V nominal, but 500 mW rating and 17 Ω ZZT; SOT23 package with different marking code | Higher power and lower impedance suit higher-current references; not AEC-Q101 qualified | Select when tighter regulation under variable load is required and automotive qualification is unnecessary |
| BZX84-C3V0,115 | Identical electrical specs, but Nexperia packaging uses 10,000/reel (13-F) and different date-code format | Same functional performance; differs only in reel quantity and traceability labeling convention | Choose for multi-source procurement where tape-and-reel volume or distributor inventory alignment matters |
Compared with MMBZ5223BS-7-F and BZX84-C3V0,115, the BZX84C3V0-7-F offers AEC-Q101 compliance and optimized thermal resistance (357 °C/W) for high-reliability automotive and industrial use, while maintaining identical Zener voltage tolerance and leakage performance.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX84C3V0-7-F is specified for nominal 3.0 V Zener breakdown at 5 mA. Its absolute maximum reverse voltage is defined by its 3.2 V upper limit at 5 mA test current - exceeding this voltage risks uncontrolled conduction or thermal runaway if power dissipation exceeds 350 mW.
Is this part suitable for use in automotive applications?
Yes - the BZX84C3V0-7-F is explicitly qualified to AEC-Q101 standards, with operating temperature range from −65°C to +150°C and full traceability for automotive subsystems including body control modules, lighting drivers, and infotainment power rails.
How does the −3.5 mV/°C temperature coefficient affect circuit performance?
This negative coefficient means the Zener voltage decreases by 3.5 mV per degree Celsius rise in junction temperature. In a 3.0 V reference, that equates to ~0.12% drift per °C - requiring thermal design consideration in enclosed or high-power-density layouts.
Can this diode replace a 3.3 V Zener in an existing design?
No - the BZX84C3V0-7-F is strictly a 3.0 V device (2.8–3.2 V range). Substituting it for a 3.3 V Zener (e.g., BZX84C3V3) would cause under-regulation, potentially leading to incorrect logic thresholds or ADC reference errors in voltage-sensitive circuits.
