Diodes Incorporated BZX84C5V6TQ-7-F

Overview

BZX84C5V6TQ-7-F from Diodes Incorporated is a 5.6 V, 150 mW surface-mount Zener diode in SOT523 package, rated for 5 mA test current with 40 Ω dynamic impedance at 5 mA and ±0.4 V zener voltage tolerance (5.2–6.0 V), used for precision voltage regulation and overvoltage protection in automotive power rails.

For engineers reviewing the BZX84C5V6TQ-7-F datasheet, BZX84C5V6TQ-7-F pinout, BZX84C5V6TQ-7-F application, or BZX84C5V6TQ-7-F equivalent, key selection criteria include zener voltage stability across temperature (±2.0 to +2.5 mV/°C), low capacitance (85 pF @ 1 MHz), AEC-Q101 qualification, and IATF 16949 manufacturing compliance.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. It delivers 5.6 V regulation at 5 mA with 40 Ω zener impedance and exhibits low leakage (<1.0 μA @ 3.36 V) and low junction-to-ambient thermal resistance (833 °C/W).

The device uses planar die construction and matte tin–annealed alloy 42 leadframe for solderability per MIL-STD-202, Method 208. Its SOT523 package supports ultra-dense PCB layouts with moisture sensitivity level 1 per J-STD-020 and UL 94V-0 flammability rating.

Key Specifications

Pinout & Package

FAQ

What is the maximum reverse voltage this Zener can clamp without damage?

The BZX84C5V6TQ-7-F has a maximum rated power dissipation of 150 mW at 25 °C. With a nominal zener voltage of 5.6 V, sustained clamping above ~26.8 mA (150 mW ÷ 5.6 V) risks thermal failure unless derated per the published power derating curve. Absolute maximum reverse voltage is not specified - operation must remain within the 5.2–6.0 V regulation band at defined test currents.

Is this part suitable for use in a precision 5.6 V reference circuit?

Yes, but with caveats: its 5.2–6.0 V tolerance and −2.0 to +2.5 mV/°C temperature coefficient limit absolute accuracy. For precision references, pair it with trimming resistors or use it in feedback loops where closed-loop correction compensates for drift. It is not a substitute for bandgap or buried-Zener references in sub-0.1% applications.

Does the SOT523 package support automated optical inspection (AOI)?

Yes - the SOT523's standardized top-view marking (R3 for BZX84C5V6TQ), consistent cathode band placement, and 0.5 mm pitch between terminals meet common AOI system requirements for solder-joint and placement verification. Its 0.33 mm profile also avoids shadowing issues in dual-camera setups.

How does AEC-Q101 qualification impact supply chain handling?

AEC-Q101 qualification mandates full PPAP documentation, IATF 16949-certified manufacturing, and lot-level traceability. At Aetrix, this translates to guaranteed material pedigree, controlled change notifications, and priority allocation during shortages - critical for Tier 1 automotive suppliers managing long-term production programs.
