Product details
Overview
BZX84C7V5Q-13-F from Diodes Incorporated is a 7.5V, 350mW surface-mount Zener diode in SOT23 package, rated for 5mA test current with 15Ω dynamic impedance at 1kHz and ±2.5% voltage tolerance (7.0–7.9V), used for precision voltage regulation and overvoltage protection in automotive power rails and sensor interface circuits.
For engineers reviewing the BZX84C7V5Q-13-F datasheet, BZX84C7V5Q-13-F pinout, BZX84C7V5Q-13-F application, or BZX84C7V5Q-13-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (357°C/W), AEC-Q101 qualification, low reverse leakage (1.0µA @ 5.0V), and automotive-grade tape-and-reel packaging (10,000 units).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent Zener characteristics, while the SOT23 package enables high-density PCB layouts and compatibility with automated pick-and-place assembly.
It delivers 7.5V regulation at 5mA test current with 15Ω Zener impedance at 1kHz and exhibits a positive temperature coefficient of +2.5mV/°C - enabling predictable drift compensation in multi-diode reference networks.
Key Specifications

|---|---|---|---|
| MMSZ4685-TP (Micro Commercial) | 7.5V nominal, 500mW rating, 30Ω ZZT, non-AEC-Q101 | Higher power margin but lacks automotive qualification and tighter impedance spec | Select for cost-sensitive industrial power supplies where AEC-Q101 is not required. |
| BZX84-C7V5,115 (Nexperia) | 7.5V nominal, 350mW, 15Ω ZZT, AEC-Q101 qualified, SOT23-3 | Identical electrical specs and qualification; differs only in marking code and reel packaging (3,000 vs. 10,000 units) | Choose for direct second-source availability with identical performance and automotive compliance. |
Compared with MMSZ4685-TP and BZX84-C7V5,115, the BZX84C7V5Q-13-F offers identical Zener performance and AEC-Q101 validation but ships in larger 10,000-unit reels - optimizing procurement logistics for high-volume automotive production runs.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX84C7V5Q-13-F has a nominal Zener voltage of 7.5V with a guaranteed range of 7.0V to 7.9V at 5mA test current. Its reverse breakdown occurs within this band - it is not rated for sustained operation above 7.9V. The absolute maximum reverse voltage before irreversible damage is defined by its 350mW power limit: at 7.9V, safe continuous current is ≤44mA.
Is this part suitable for use in a temperature-compensated reference circuit?
Yes - its +2.5mV/°C temperature coefficient is well-documented and stable across -65°C to +150°C. Paired with a complementary negative-TC device (e.g., forward-biased diode), it enables low-drift reference designs. The 15Ω Zener impedance ensures minimal interaction with compensation network impedance.
How does the "Q" suffix affect the part's specifications?
Per Diodes Incorporated's ordering guide, the "Q" denotes automotive qualification per AEC-Q101. All electrical parameters (VZ, ZZT, IR) remain identical to standard versions, but the Q-grade undergoes additional stress testing - including HTOL, TCT, and ESD - ensuring reliability in automotive under-hood environments.
Can this Zener replace a 7.5V TL431-based shunt regulator?
No - the BZX84C7V5Q-13-F is a two-terminal passive Zener, lacking the adjustable feedback, low output impedance, and current-sinking capability of the TL431. It provides fixed-voltage clamping only. For active regulation, a TL431 remains necessary; this Zener serves best as a simple, low-cost voltage reference or overvoltage limiter.
