Product details
Overview
BZX84C2V7Q-7-F from Diodes Incorporated is an automotive-grade 2.7 V, 350 mW surface-mount Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in low-power analog rails and sensor biasing circuits. It delivers a nominal Zener voltage of 2.7 V at 5 mA test current, with ±0.2 V tolerance (2.5–2.9 V), 100 Ω dynamic impedance at 5 mA, and −3.5 mV/°C temperature coefficient.
For engineers reviewing the BZX84C2V7Q-7-F datasheet, BZX84C2V7Q-7-F pinout, BZX84C2V7Q-7-F application, or BZX84C2V7Q-7-F equivalent, key selection criteria include its AEC-Q101 qualification, low-voltage regulation stability under varying temperature, tight Zener voltage distribution, and compatibility with automated SMT assembly on space-constrained PCBs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across load variations and supply fluctuations. Its planar die construction ensures consistent electrical performance and long-term reliability under thermal cycling.
The device exhibits a negative temperature coefficient (−3.5 mV/°C) and is characterized at 5 mA Zener test current, with maximum reverse leakage of 20 µA at 1.0 V and forward voltage of 0.9 V at 10 mA - enabling predictable clamping behavior in both forward and reverse conduction paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5223BS-7-F | 2.7 V Zener, 200 mW rating, SOT23 package, −3.5 mV/°C TC, but not AEC-Q101 qualified | Limited to commercial-grade consumer or industrial use; unsuitable for automotive ECUs | Select when cost sensitivity outweighs automotive qualification requirement |
| BZX84-C2V7LT1G | 2.7 V Zener, 350 mW, SOT23, AEC-Q101 qualified, but uses different marking code and packaging (tape & reel 3,000 pcs vs. 3,000 pcs) | Functionally identical; differs only in ordering suffix and traceability documentation | Prefer for legacy design continuity where ON Semiconductor sourcing is mandated |
Compared with MMBZ5223BS-7-F and BZX84-C2V7LT1G, BZX84C2V7Q-7-F uniquely combines AEC-Q101 compliance, 350 mW dissipation, and Diodes Inc.'s green material specification - making it optimal for next-generation automotive and high-reliability industrial designs requiring full regulatory alignment.

FAQ
What is the maximum reverse voltage before breakdown for BZX84C2V7Q-7-F?
The nominal Zener voltage is 2.7 V at 5 mA test current, with guaranteed minimum and maximum values of 2.5 V and 2.9 V respectively. Breakdown occurs within this range depending on unit-to-unit variation and operating temperature - no separate "maximum reverse voltage" is specified beyond the rated Zener range.
Is BZX84C2V7Q-7-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 D3V3M1U2SOT-7-F (3.3 V, ±5 kV contact ESD) are recommended instead.
How does the −3.5 mV/°C temperature coefficient affect circuit performance?
Over a 100°C range (−40°C to +60°C), the Zener voltage shifts approximately −350 mV - meaning a 2.7 V reference may drop to ~2.35 V. This must be accounted for in precision references; compensation techniques include using complementary TC components or selecting higher-voltage Zeners with near-zero TC.
Can BZX84C2V7Q-7-F replace BZX84C2V4Q-7-F in existing designs?
No - the 2.4 V and 2.7 V variants have different Zener voltages, impedance profiles, and temperature coefficients. Substitution would alter reference levels and regulation margins; redesign validation is required if changing Zener voltage grades.
