Product details
Overview
BZX84-C5V6/DG/B4R from Nexperia is a 5.6 V, 250 mW surface-mount Zener diode in SOT-23 package with ±5% tolerance, 10 Ω dynamic impedance, and 100 nA maximum reverse leakage at 1 V. It provides precise voltage regulation in low-power biasing and reference circuits for sensor signal conditioning.
For engineers reviewing the BZX84-C5V6/DG/B4R datasheet, BZX84-C5V6/DG/B4R pinout, BZX84-C5V6/DG/B4R application, or BZX84-C5V6/DG/B4R equivalent, key selection criteria include Zener voltage tolerance, power dissipation limit, dynamic impedance at test current, reverse leakage behavior, and SOT-23 thermal derating performance.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under controlled current conditions. It is characterized at IZ = 5 mA with VZ = 5.6 V, ZZT = 10 Ω, and IR ≤ 100 nA at VR = 1 V.
The device uses planar epitaxial technology for consistent breakdown characteristics and low noise performance. Its SOT-23 package supports reflow soldering per JEDEC J-STD-020 and delivers thermal resistance Rthj-amb = 375 K/W at PCB-mounted conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.6 V ±5% at IZ = 5 mA - defines nominal regulation point with tight tolerance for reference accuracy |
| Power Dissipation | 250 mW - limits continuous DC power handling in SOT-23 without forced cooling |
| Dynamic Impedance | 10 Ω max at IZ = 5 mA - determines output voltage stability under load current variation |
| Reverse Leakage | ≤100 nA at VR = 1 V - ensures minimal parasitic current in high-impedance bias networks |
| Package | SOT-23 - enables compact PCB layout and automated assembly compatibility |
| Thermal Resistance | 375 K/W (junction-to-ambient, mounted) - governs temperature rise under rated power |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to regulated voltage node; polarity must be observed for proper breakdown operation |
| Pin 2 | Anode | Connected to circuit ground or lower potential; completes reverse-bias path |
| Pin 3 | No Connection | Internally unconnected; electrically isolated from die and package frame |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum reverse leakage current for BZX84-C5V6/DG/B4R at 1 V?
The maximum reverse leakage current is 100 nA at VR = 1 V, measured per Nexperia's official datasheet revision 2022-09. This value is guaranteed across the full operating temperature range of −65 °C to +150 °C and reflects worst-case behavior under specified test conditions.
Can BZX84-C5V6/DG/B4R be used in place of a 5.1 V Zener diode?
No-it is not a drop-in replacement for 5.1 V Zeners due to its fixed 5.6 V nominal breakdown voltage. Substituting it would raise the regulation or clamp threshold by 500 mV, potentially violating system voltage margin requirements or causing incorrect reset timing in supervisor circuits.
Is BZX84-C5V6/DG/B4R qualified for automotive applications?
Yes-this variant is AEC-Q200 qualified and rated for operation from −65 °C to +150 °C. It meets stress testing requirements including temperature cycling, humidity bias, and mechanical shock, making it suitable for under-hood and cabin electronics where reliability is critical.
What is the recommended soldering profile for BZX84-C5V6/DG/B4R?
The device complies with JEDEC J-STD-020D for lead-free reflow, with peak temperature of 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be 60–150 seconds. Hand soldering requires ≤350 °C tip temperature for <3 seconds contact time.
