Product details
Overview
BZX84-C5V6,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for low-power precision voltage reference and overvoltage protection in signal conditioning and power rail stabilization circuits. It delivers 5.6 V nominal breakdown at 5 mA, with 400 Ω max differential resistance, 1 μA max reverse current at 4.0 V, and -2.0 to +2.5 mV/K temperature coefficient.
For engineers reviewing the BZX84-C5V6,235 datasheet, BZX84-C5V6,235 pinout, BZX84-C5V6,235 application, or BZX84-C5V6,235 equivalent, this page provides verified Zener parameters, thermal derating guidance, SOT23 terminal mapping, and direct alternatives for voltage reference design, ESD clamping, and analog sensor biasing where ±5 % tolerance and 250 mW dissipation are acceptable.
Technical Context
This Zener diode operates in reverse-biased avalanche mode to maintain stable voltage across its cathode–anode terminals under varying load and temperature conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA, with differential resistance ≤400 Ω ensuring minimal voltage shift under current variation.
The device features non-repetitive peak reverse power dissipation of 40 W (100 μs pulse), junction-to-ambient thermal resistance of 500 K/W on FR4 PCB, and operates across -55 °C to +150 °C ambient range - enabling use in industrial control and automotive-adjacent non-safety-critical subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.20 V to 6.00 V at IZ = 5 mA - defines usable regulation window under standard test conditions |
| Differential Resistance (rdif) | ≤400 Ω - limits output voltage deviation during load current changes |
| Reverse Current (IR) | ≤1 μA at VR = 4.0 V - ensures low leakage before breakdown onset |
| Temperature Coefficient (SZ) | -2.0 to +2.5 mV/K at IZ = 5 mA - quantifies VZ drift per degree Celsius |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - supports transient surge suppression without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low conduction loss in forward-biased configurations |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; compact 2.9 mm × 1.3 mm footprint, 1.1 mm height, and tin-plated copper terminations compatible with reflow and wave soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node; reverse-biased operation requires cathode at higher potential |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection - must remain unconnected on PCB |
| 3 | Cathode (K) | Connected to regulated voltage rail; carries reverse current during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., supply rail monitoring |
| 250 mW total power dissipation | Supports continuous operation in space-constrained consumer and industrial PCBs without heatsinking |
| 40 W non-repetitive peak power rating | Provides robustness against short-duration ESD or inductive kick events in sensor interfaces |
| 150 °C maximum junction temperature | Permits reliable operation in high-temperature environments such as engine bay proximity electronics |
| SOT23 package compatibility | Ensures drop-in replacement capability with industry-standard pick-and-place equipment and reflow profiles |
Applications
| Power Supply Rail Clamping | Sensor Bias Reference |

FAQ
What is the maximum continuous reverse current the BZX84-C5V6,235 can sustain at 25 °C ambient?
The device sustains up to 44.6 mA continuous reverse current at 25 °C ambient, calculated from Ptot = 250 mW and VZ = 5.6 V (250 mW ÷ 5.6 V ≈ 44.6 mA). Derating applies above 25 °C per the 500 K/W thermal resistance specification.
Can the BZX84-C5V6,235 be used in place of a BZX84-B5V6 for tighter voltage tolerance?
No - the BZX84-C5V6,235 has ±5 % tolerance (5.20 V to 6.00 V), whereas the BZX84-B5V6 offers ±2 % (5.49 V to 5.71 V). Substituting introduces up to ±3 % additional voltage uncertainty, which may violate regulation requirements in precision analog circuits.
Is Pin 2 electrically functional, and what happens if it is soldered to ground?
Pin 2 is internally not connected (n.c.) and must remain unconnected on the PCB. Soldering it to ground creates a parasitic path that may cause unpredictable leakage, thermal imbalance, or premature failure due to unintended current flow through the package mold compound.
How does the temperature coefficient affect regulation accuracy over -40 °C to +85 °C ambient?
With SZ = -2.0 to +2.5 mV/K, VZ shifts by up to ±315 mV across a 125 K range (e.g., -40 °C to +85 °C), resulting in a worst-case regulation error of ±5.6 % relative to 5.6 V - acceptable for non-precision functions like overvoltage clamping but insufficient for reference-grade applications.
