Product details
Overview
BZX84-C6V8,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for low-power voltage reference and overvoltage protection in space-constrained PCBs. It delivers 6.8 V nominal breakdown at 5 mA, with 80 Ω max differential resistance, 15 μA reverse current at 4.0 V, and 1.2 mV/K temperature coefficient - enabling stable regulation in consumer power supplies and signal conditioning circuits.
For engineers reviewing the BZX84-C6V8,215 datasheet, BZX84-C6V8,215 pinout, BZX84-C6V8,215 application, or BZX84-C6V8,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W to solder point), non-repetitive surge capability (6.0 A peak), and SOT23 footprint compatibility with high-density layouts.
Technical Context
This discrete Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its cathode–anode terminals. Its 6.4 V to 7.2 V working voltage range (at IZ = 5 mA) and low 80 Ω dynamic impedance ensure tight regulation under varying load currents up to 200 mA DC.
Thermal design relies on junction-to-solder-point resistance of 330 K/W and maximum junction temperature of 150 °C, requiring careful PCB copper area allocation. The device exhibits a positive temperature coefficient (+1.2 mV/K) above 6 V, reducing drift in ambient-temperature-varying applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V to 7.2 V at 5 mA - defines usable regulation window for precision biasing |
| Differential Resistance (rdif) | ≤80 Ω - ensures minimal output voltage shift under load current changes |
| Reverse Current (IR) | ≤15 μA at VR = 4.0 V - guarantees low leakage in standby or sensing circuits |
| Temperature Coefficient (SZ) | +1.2 mV/K at 5 mA - quantifies voltage drift per degree Celsius rise |
| Non-repetitive Peak Current (IZSM) | 6.0 A for 100 μs - supports transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets continuous DC power limit on standard FR4 PCB |
| Junction-to-Solder-Point Rth | 330 K/W - enables thermal modeling from die to PCB copper for reliability analysis |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Figure 12 (reflow) and Figure 13 (wave soldering); dimensions 2.9 mm × 1.3 mm × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in regulation path |
| 2 | Not Connected (n.c.) | Internally unconnected lead; must remain floating or tied to ground only if required by layout |
| 3 | Cathode (K) | Reverse-biased terminal; connects to regulated output node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight accuracy is not critical (e.g., supply rail monitoring) |
| 250 mW total power dissipation | Supports continuous operation in low-current bias networks without heatsinking |
| 6.0 A non-repetitive peak reverse current | Provides robust ESD and surge immunity per IEC 61000-4-2 Level 4 when used with series impedance |
| 330 K/W junction-to-solder-point thermal resistance | Allows direct thermal coupling to PCB copper pour for improved long-term reliability |
| SOT23 footprint compatibility | Ensures drop-in replacement in legacy designs using industry-standard 0.95 mm pitch land pattern |

|---|---|---|---|
| ON Semiconductor MMBZ5234BS-7-F | 6.8 V ±5 %, 200 mW Ptot, 100 Ω rdif, SOT23 package | Higher dynamic impedance reduces regulation precision in low-noise analog references | Select when legacy ON Semi sourcing is required and 100 Ω rdif is acceptable |
| Vishay BZX84-C6V8-E3-08 | 6.8 V ±5 %, 300 mW Ptot, 80 Ω rdif, same SOT23 footprint | Higher power rating allows extended DC operation at elevated ambient temperatures | Select for industrial environments >85 °C ambient where 250 mW derating is limiting |
Compared with MMBZ5234BS-7-F, BZX84-C6V8,215 offers tighter dynamic impedance for improved line regulation; versus BZX84-C6V8-E3-08, it trades 50 mW power headroom for Nexperia's optimized thermal resistance and traceable automotive-grade wafer processing.

FAQ
What is the maximum continuous forward current for BZX84-C6V8,215?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA per pulse test conditions (tp ≤ 100 μs). In normal Zener operation, forward bias is avoided - the diode functions exclusively in reverse breakdown. Forward voltage is specified only for characterization (VF ≤ 0.9 V at 10 mA).
Can BZX84-C6V8,215 be used in automotive applications?
No - this part is explicitly marked non-automotive qualified per Nexperia's Rev. 7 datasheet. It lacks AEC-Q101 qualification and automotive-specific testing. For automotive use, select the BZX84-Q series (e.g., BZX84-Q6V8,215), which undergoes extended temperature cycling, humidity testing, and failure analysis per automotive standards.
How does the "215" suffix in BZX84-C6V8,215 affect specifications?
The "215" denotes the specific tape-and-reel packaging variant: 3,000 units per reel, 8 mm tape width, EIA-481-D compliant carrier. It does not alter electrical or thermal characteristics - all BZX84-C6V8 variants share identical Zener voltage, power rating, and package dimensions.
Is pin 2 truly unconnected, or can it be used as a thermal pad?
Pin 2 is internally not connected (n.c.) per Table 2 and Figure 11. It must not be bonded to substrate or used for thermal conduction. Thermal performance relies solely on pins 1 (anode) and 3 (cathode); attaching pin 2 to copper may cause shorting or mechanical stress during reflow due to misalignment tolerance.
