BZX84C SOT-23 Zener Diode Variants
Diodes Incorporated BZX84C variants are compact SOT-23 and small-package Zener diodes for voltage clamps, references, bias regulation, and low-energy protection networks.
Small-package Zener options for board-level clamps and references
Compare BZX84C variants by Zener voltage, tolerance, package, power rating, array option, and packing suffix.
The BZX84C family from Diodes Incorporated groups small-signal Zener diodes in SOT-23 and related compact packages. The variants cover many nominal Zener voltages and include single-diode and selected array-style package options. They are commonly used for simple rail clamps, bias references, interface protection, voltage limiting, and low-energy shunt regulation.
BZX84C selection is driven by the actual circuit current and package power dissipation, not just the printed voltage. Verify Zener voltage tolerance, test current, dynamic impedance, leakage, thermal resistance, pulse exposure, package type, and automotive qualification where required. Similar voltage values may exist in SOT-23, SOT-323, SOT-363, or SOT-523 style variants with different power limits.

Ordering Code Differences
How suffixes on BZX84C map to package, grade, and reel options.
[{"code":"BZX84Cxx","meaning":"The number identifies nominal Zener voltage, such as 3V3, 5V1, 12, or 24."},{"code":"S, T, W suffix markers","meaning":"Often point to alternate small packages or array styles; verify the datasheet."},{"code":"Q marker","meaning":"May indicate automotive-qualified options in selected order codes."},{"code":"-7 or -13","meaning":"Tape-and-reel packing indicators."}]
How to Choose the Right BZX84C Zener Diodes
Design at real current
Zener voltage is specified at a test current; clamp voltage shifts at lighter or heavier current.
Derate the package
Small SMD packages have limited continuous dissipation and need thermal margin.
Check leakage
Battery and high-impedance analog nodes may be sensitive to reverse leakage.
