Product details
Overview
BZX84C2V4-7-F from Diodes Incorporated is a 2.4 V, 350 mW surface-mount Zener diode in SOT23 package, rated for 5 mA test current with ±0.2 V tolerance, 100 Ω dynamic impedance at 5 mA, and -3.5 mV/°C temperature coefficient - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the BZX84C2V4-7-F datasheet, BZX84C2V4-7-F pinout, BZX84C2V4-7-F application, or BZX84C2V4-7-F equivalent, key selection criteria include zener voltage stability at low current, thermal coefficient matching across operating temperature, SOT23 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode with nominal 2.4 V regulation at IZT = 5 mA. Its planar die construction ensures stable voltage output under transient load conditions and supports automated pick-and-place assembly.
It exhibits a negative temperature coefficient of -3.5 mV/°C, enabling predictable drift compensation in temperature-sensitive references. Maximum reverse current is limited to 50 µA at 1.0 V, ensuring low leakage in standby circuits.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 2.4 V nominal, 2.2–2.6 V range at 5 mA - defines precise clamping threshold for 3.3 V rail protection |
| Power Dissipation | 350 mW - supports continuous operation at up to 145 mA at 2.4 V without heatsinking |
| Zener Impedance (ZZT) | 100 Ω at 5 mA - limits regulation error to <±0.5 V under ±5 mA load variation |
| Reverse Leakage (IR) | 50 µA max at 1.0 V - ensures minimal quiescent current draw in battery-powered sensor nodes |
| Temperature Coefficient | -3.5 mV/°C - enables predictable voltage shift for temperature-compensated biasing networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | 2.4 V, 350 mW, SOT23 but with 120 Ω ZZT and -2.5 mV/°C TC | Higher impedance causes greater regulation error under load variation; less suitable for precision references | Select when cost is prioritized over voltage stability and temperature tracking |
| BZX84-C2V4,115 | Same 2.4 V spec but in SOT23-3L with 100 Ω ZZT, yet not AEC-Q101 qualified | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Choose only for commercial-grade consumer products where qualification is not required |
Compared with MMBZ5221BS-7-F and BZX84-C2V4,115, the BZX84C2V4-7-F delivers superior thermal coefficient matching and automotive qualification - making it the preferred choice for high-reliability industrial and automotive voltage reference designs requiring long-term stability.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX84C2V4-7-F has a nominal zener voltage of 2.4 V at 5 mA test current, with a guaranteed breakdown range of 2.2 V to 2.6 V. It does not specify a separate "maximum reverse voltage" rating - operation beyond 2.6 V at rated current will cause increasing conduction, and sustained operation above its 350 mW power limit risks thermal failure.
Is this part suitable for use in automotive applications?
Yes - the BZX84C2V4-7-F is explicitly qualified to AEC-Q101 standards, confirming its reliability for automotive electronics including body control modules, lighting drivers, and sensor interfaces. Its green molding compound and SOT23 package meet automotive environmental and assembly requirements.
How does the temperature coefficient affect circuit performance?
With a temperature coefficient of -3.5 mV/°C, the zener voltage decreases linearly as ambient temperature rises. Over a -40°C to +125°C range, this results in ~580 mV total drift - requiring compensation in precision references, but beneficial for offset cancellation in matched transistor bias networks.
Can this Zener be used in place of a 2.5 V reference IC?
No - while it provides 2.4 V regulation, it lacks the low output impedance, tight initial tolerance, and buffered output of dedicated reference ICs like the REF3025. Its 100 Ω dynamic impedance and ±0.2 V tolerance make it appropriate for clamping and coarse biasing, not precision analog measurement.
