Diodes Incorporated BZX84C5V6Q-13-F

Overview

BZX84C5V6Q-13-F from Diodes Incorporated is a 5.6 V, 350 mW surface-mount Zener diode in SOT23 package, rated for 1 mA maximum reverse leakage at 2.0 V and 40 Ω dynamic impedance at 5 mA test current, used for precision voltage regulation and overvoltage protection in automotive power rails and sensor biasing circuits.

For engineers reviewing the BZX84C5V6Q-13-F datasheet, BZX84C5V6Q-13-F pinout, BZX84C5V6Q-13-F application, or BZX84C5V6Q-13-F equivalent, key selection criteria include zener voltage tolerance (±7.1%), temperature coefficient (−2.0 mV/°C), AEC-Q101 qualification, and automotive-grade tape-and-reel packaging (10,000 units).

Technical Context

This Zener diode operates in reverse breakdown mode with a nominal zener voltage of 5.6 V at 5 mA test current, exhibiting a tight 5.2–6.0 V range and −2.0 mV/°C temperature coefficient to minimize drift across −65°C to +150°C operating range.

Its planar die construction and matte tin-plated Alloy 42 leadframe ensure stable parametric performance under thermal cycling and high-reliability automotive conditions, while its 350 mW power dissipation rating is validated under ambient-temperature terminal conditions per J-STD-020 Level 1 moisture sensitivity.

FAQ

What is the maximum reverse voltage (V_R) at which BZX84C5V6Q-13-F guarantees ≤1.0 µA leakage?

The device guarantees ≤1.0 µA reverse leakage current at V_R = 2.0 V, as specified in the Electrical Characteristics table. This value is measured at T_A = +25°C and defines the upper limit of usable reverse bias before significant leakage begins, critical for low-power sensor biasing applications.

Is BZX84C5V6Q-13-F pin-compatible with standard SOT23 Zener diodes from other manufacturers?

Yes-it uses the industry-standard SOT23-3 package with anode (Pin 1), cathode (Pin 2), and internal tab (Pin 3) pinout confirmed in Diodes' official package outline. Mechanical dimensions (e.g., 2.40 mm length, 1.30 mm width) align with JEDEC MO-215, ensuring physical compatibility with existing SOT23 footprints.

Does the "Q" suffix in BZX84C5V6Q-13-F indicate AEC-Q101 qualification?

Yes-the "Q" denotes automotive qualification per AEC-Q101. This is explicitly defined in Diodes' Ordering Information table, where "(Type Number)Q-13-F" identifies the automotive-grade variant with enhanced reliability testing, green material content, and traceable lot documentation required for automotive Tier 1 supply chains.

How does the −2.0 mV/°C temperature coefficient affect regulation accuracy over temperature?

At −2.0 mV/°C, the zener voltage shifts −2.0 mV per degree Celsius rise from 25°C. Over a −40°C to +125°C range (165°C delta), total drift is ±330 mV-within the 5.2–6.0 V specification window. This enables predictable compensation in temperature-sensitive references like engine coolant sensor interfaces.
