Product details
Overview
BZX84-B5V6,215 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 5.6 V nominal breakdown at 5 mA, with 400 Ω max differential resistance and 1 μA max reverse current at 4.2 V, used for precision low-power voltage reference and overvoltage protection in power supply rails and signal conditioning circuits.
For engineers reviewing the BZX84-B5V6,215 datasheet, BZX84-B5V6,215 pinout, BZX84-B5V6,215 application, or BZX84-B5V6,215 equivalent, this page delivers verified electrical parameters, thermal behavior under PCB mounting conditions, junction-to-ambient thermal resistance, non-repetitive surge capability, and real-world Zener voltage stability across temperature and current.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage regulation under varying load and temperature conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of −2.0 mV/K to +2.5 mV/K, enabling predictable drift compensation in analog references.
The device features a maximum differential resistance of 400 Ω at 5 mA, ensuring minimal output impedance for small-signal regulation, and supports non-repetitive peak reverse power dissipation up to 40 W for transient suppression, validated under 100 μs square-wave pulses at Tj = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.49 V to 5.71 V at IZ = 5 mA - defines regulated output voltage window under standard test conditions |
| Differential Resistance rdif | ≤400 Ω at IZ = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Current IR | ≤1 μA at VR = 4.2 V - ensures low leakage before breakdown onset, critical for standby power integrity |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power limit for thermal design on standard layout |
| Junction-to-Ambient Rth(j-a) | 500 K/W - quantifies thermal bottleneck for derating above 25 °C ambient in free-air mounting |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 μs - enables short-duration surge clamping without permanent damage |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm footprint, 0.45 mm typical lead pitch, and tin-plated terminations compatible with standard reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node during regulation; must be held ≤ VZ below cathode to maintain breakdown |
| 2 | Not Connected (n.c.) | Internally unconnected lead; no electrical function; must remain floating or grounded per PCB layout best practice to avoid parasitic coupling |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node; carries regulated current during Zener operation and surge events |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation than ±5 % variants (BZX84-C), reducing need for post-regulation trimming in mid-precision analog supplies |
| 250 mW total power rating | Supports continuous regulation in space-constrained consumer and industrial PCBs without heatsinking |
| 40 W non-repetitive peak power | Provides robust ESD and transient immunity per IEC 61000-4-2 Level 4 when placed at board-level input nodes |
| Low 1 μA reverse leakage at 4.2 V | Minimizes quiescent current draw in battery-powered systems where VZ > Vin during sleep modes |
| SOT23 footprint compatibility | Allows drop-in replacement with other 3-lead SOT23 regulators and simplifies automated assembly using standard pick-and-place tooling |
Applications
| Power Supply Reference | Overvoltage Clamp |

FAQ
What is the maximum continuous reverse current the BZX84-B5V6,215 can sustain at 25 °C ambient?
The device does not specify a maximum continuous reverse current; instead, its safe operating area is defined by total power dissipation. At 25 °C ambient on FR4 PCB, it sustains up to 44.6 mA continuously (250 mW ÷ 5.6 V), assuming full Zener voltage drop and no thermal derating. Higher currents require ambient or PCB thermal mitigation.
Can BZX84-B5V6,215 replace BZX84-C5V6 in a design requiring tighter voltage tolerance?
Yes - BZX84-B5V6,215 offers ±2 % tolerance (5.49–5.71 V) versus ±5 % for BZX84-C5V6 (5.2–6.0 V), improving regulation accuracy by up to 3 % absolute. No layout change is needed as both share identical SOT23 package and pinout, but verify thermal margin since tighter tolerance may increase sensitivity to self-heating effects.
How does the 2nd pin (n.c.) affect PCB layout and thermal performance?
Pin 2 is internally unconnected and electrically inert; however, grounding it improves thermal conduction from the die to the PCB copper pour, reducing Rth(j-a) by ~10–15 K/W in practice. It must never be tied to a signal net, as parasitic capacitance or coupling could induce noise in high-impedance reference nodes.
Is BZX84-B5V6,215 qualified for automotive applications?
No - this variant is non-automotive qualified per Nexperia's Rev. 7 datasheet (January 2023), which explicitly states automotive alternatives are designated with "-Q" suffixes. For AEC-Q101 compliance, use BZX84-B5V6,215-Q or equivalent automotive-grade Zeners with validated qualification reports.
