Product details
Overview
BZX84W-C5V6F from Nexperia is a ±5 % tolerance Zener diode in SOT323 (SC-70) package, rated for 5.6 V nominal regulation voltage at 5 mA, with 400 Ω typical differential resistance and 1.2 mV/K positive temperature coefficient. It delivers stable voltage reference in low-power analog circuits, ESD protection clamping networks, and precision biasing for op-amp input stages.
For engineers reviewing the BZX84W-C5V6F datasheet, BZX84W-C5V6F pinout, BZX84W-C5V6F application, or BZX84W-C5V6F equivalent, key selection criteria include Zener voltage tolerance, thermal coefficient sign/magnitude, junction-to-ambient thermal resistance, reverse leakage at VR = 2 V, and SOT323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 5.6 V reference across load variations and supply fluctuations. Its 1.2 mV/K positive temperature coefficient compensates for negative drift in associated circuitry, enabling improved thermal stability in voltage references over −55 °C to +150 °C ambient range.
The device exhibits 1 µA maximum reverse current at VR = 2 V and supports non-repetitive surge handling up to 40 W for 100 µs pulses. Its 455 K/W junction-to-ambient thermal resistance reflects performance on standard FR4 PCB with single-sided copper and tin-plated finish.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines regulation window for precision reference design |
| Differential Resistance (rdif) | 400 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - enables predictable thermal drift compensation in reference chains |
| Reverse Current (IR) | 1 µA max at VR = 2 V - ensures low quiescent power loss in standby bias networks |
| Total Power Dissipation (Ptot) | 275 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Junction-to-Ambient Rth(j-a) | 455 K/W - informs thermal derating requirements for operation above 25 °C ambient |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction loss when used as forward-biased clamp or series element |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package with 3 leads, 1.3 mm × 1.8 mm footprint, and 0.65 mm lead pitch. Designed for reflow and wave soldering per IPC-7351B standards.

|---|---|---|
| 1 | Anode (A) | Forward conduction terminal; connects to lower-potential node in Zener configuration |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection; must remain unconnected on PCB |
| 3 | Cathode (K) | Reverse-bias terminal; connects to higher-potential node for Zener operation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5232BS | Same 5.6 V nominal, ±5 %, but SOT-323 package with 2-pin configuration (no n.c. pin) | Lacks isolated n.c. terminal; requires PCB layout revision to accommodate 2-pin footprint | Select when board redesign is acceptable and lowest-cost sourcing is prioritized |
| Vishay BZX84-C5V6 | Identical electrical specs and 3-pin SOT-323, but marked with different code (N3%) and RoHS-compliant plating variant | Drop-in mechanical replacement; same thermal performance and soldering profile | Prefer for dual-sourcing continuity where marking or plating compliance differs |
Compared with MMBZ5232BS, BZX84W-C5V6F offers pin-compatible integration without footprint change; versus BZX84-C5V6, it provides identical regulation performance with updated manufacturing traceability and revised qualification status per Nexperia Rev. 2 specification.

FAQ
What is the maximum continuous power dissipation for BZX84W-C5V6F at 70 °C ambient?
At 70 °C ambient, the device's power dissipation must be derated from its 275 mW rating at 25 °C using the 455 K/W thermal resistance. The allowable power is 275 mW × (1 − (70 − 25)/125) = 187 mW, assuming Tj(max) = 150 °C and standard FR4 mounting conditions.
Does the n.c. pin require grounding or floating in PCB layout?
Pin 2 is internally not connected and must remain electrically floating on the PCB. No trace, pad, or ground pour should connect to this terminal, as doing so may compromise thermal performance or introduce unintended coupling paths in high-frequency applications.
How does the +1.2 mV/K temperature coefficient affect regulation accuracy over temperature?
Over a 100 °C range (−25 °C to +75 °C), the Zener voltage shifts by +120 mV, or +2.1 % of nominal 5.6 V. This drift is linear and predictable, allowing system-level compensation in calibration routines or matching with complementary negative-drift components.
Can BZX84W-C5V6F be used in place of a 5.1 V Zener for higher-voltage margin?
No - substituting a 5.6 V Zener for a 5.1 V design alters regulation setpoint by +0.5 V, potentially exceeding downstream IC absolute maximum ratings or violating feedback loop setpoints. Voltage-specific Zeners are not interchangeable without circuit recalculations and validation.
