Product details
Overview
BZX84C7V5-7-F from Diodes Incorporated is a 350 mW surface-mount Zener diode with nominal zener voltage 7.5 V (±0.9 V tolerance), 15 Ω dynamic impedance at 5 mA test current, and 1.0 µA maximum reverse leakage at 5.0 V. It operates in SOT23 package and serves as precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX84C7V5-7-F datasheet, BZX84C7V5-7-F pinout, BZX84C7V5-7-F application, or BZX84C7V5-7-F equivalent, key selection criteria include zener voltage stability across temperature (2.5 mV/°C TC), low capacitance (≈15 pF), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode uses planar die construction to ensure stable breakdown characteristics and tight voltage distribution. Its 7.5 V nominal zener voltage is specified at 5.0 mA test current, with 15 Ω impedance at that point and 80 Ω at knee current (1.0 mA).
The device exhibits a positive temperature coefficient of +2.5 mV/°C near 7.5 V, enabling predictable drift compensation in reference designs. Thermal resistance is 357 °C/W (junction-to-ambient, free-air), supporting operation from –65 °C to +150 °C.
Key Specifications

| Zener Impedance (ZZT) | 15 Ω at 5 mA - determines output voltage variation under load current changes |
| Reverse Leakage (IR) | 1.0 µA max at 5.0 V - ensures minimal standby current in high-impedance bias networks |
| Temperature Coefficient | +2.5 mV/°C - enables predictable voltage drift compensation in temperature-sensitive references |
| Total Capacitance | ≈15 pF at 1 V reverse - limits high-frequency noise coupling in RF-adjacent signal paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5236BS-7-F | 6.8 V nominal, 10 Ω ZZT, 100 mW rating | Lower power and voltage; suited for 5 V rail clamping only | Select when lower dissipation and tighter impedance are prioritized over voltage match |
| BZX84-C7V5,115 | Same 7.5 V spec but in Nexperia's SOT23, 300 mW rating, no AEC-Q101 | Lacks automotive qualification; suitable for commercial-grade consumer devices | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not required |
Compared with MMBZ5236BS-7-F and BZX84-C7V5,115, the BZX84C7V5-7-F uniquely combines 7.5 V regulation, 350 mW capability, and AEC-Q101 qualification-making it optimal for automotive and industrial voltage reference nodes requiring both precision and ruggedness.

FAQ
What is the maximum reverse voltage before breakdown for BZX84C7V5-7-F?
The nominal zener voltage is 7.5 V with a guaranteed range of 7.0 V to 7.9 V at 5 mA test current. Breakdown begins gradually below this range, but the device is rated for stable regulation only within the specified VZ window. At 5.0 V reverse bias, leakage remains ≤1.0 µA.
Is BZX84C7V5-7-F suitable for use in automotive applications?
Yes - it is qualified to AEC-Q101 standards, tested for high-temperature operation up to +150 °C, and manufactured with halogen- and antimony-free "Green" materials compliant with automotive supply chain requirements.
How does the SOT23 package affect thermal performance?
In free-air conditions, its thermal resistance is 357 °C/W (junction-to-ambient). When mounted on FR-4 PCB with recommended pad layout, RθJA improves to 417 °C/W, allowing full 350 mW dissipation only with adequate copper area and airflow.
Can BZX84C7V5-7-F replace BZX84C6V8 in an existing design?
Only if the circuit tolerates a 0.7 V increase in clamping voltage and accounts for differences in temperature coefficient (+2.5 mV/°C vs. +1.2 mV/°C) and dynamic impedance (15 Ω vs. 15 Ω at 5 mA, but 80 Ω vs. 80 Ω at 1 mA). Verify stability under worst-case load and temperature.
