Product details
Overview
BZX84J-C6V8,115 from Nexperia is a Zener voltage regulator diode in SOD323F (SC-90) package, designed for precision voltage reference and overvoltage protection in low-power circuits. It delivers 6.8 V nominal Zener voltage at 5 mA test current, ±5 % tolerance, 80 Ω differential resistance, and 150 °C maximum junction temperature - deployed in automotive sensor signal conditioning and microcontroller I/O rail clamping.
For engineers reviewing the BZX84J-C6V8,115 datasheet, BZX84J-C6V8,115 pinout, BZX84J-C6V8,115 application, or BZX84J-C6V8,115 equivalent, key selection criteria include Zener voltage accuracy under 5 mA bias, thermal resistance to ambient (230 K/W), AEC-Q101 qualification status, and non-repetitive surge capability (12 A peak reverse current at 100 µs pulse).
Technical Context
This Zener diode operates in reverse breakdown mode with stable regulation across 1 mA to 20 mA DC current range. Its temperature coefficient of +1.2 mV/K at 5 mA enables predictable drift compensation in temperature-sensitive references.
The device exhibits low forward voltage (1.1 V at 100 mA) and minimal junction capacitance (215 pF at 0 V), supporting fast transient response in clamp circuits while maintaining low leakage (<0.5 µA at 5.44 V reverse).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V to 7.2 V at IZ = 5 mA - defines precise clamping threshold for 6.8 V nominal rail protection |
| Tolerance | ±5 % - ensures consistent regulation across production batches without binning |
| Differential Resistance (rdiff) | 80 Ω max - limits output impedance variation under load changes in reference circuits |
| Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - supports continuous operation on standard FR4 PCB with 1 cm² cathode pad |
| Non-repetitive Peak Current (IZSM) | 12 A at tp = 100 µs - provides robust ESD/surge immunity per IEC 61000-4-2 Level 4 |
| Thermal Resistance (Rth(j-a)) | 230 K/W - determines junction-to-ambient temperature rise under steady-state power loading |
| Reverse Leakage (IR) | 0.5 µA max at VR = 5.44 V - minimizes standby current in battery-powered voltage monitor circuits |
Pinout & Package
Package: SOD323F (SC-90), ultra-small surface-mount plastic package with flat leads; dimensions 2.7 mm × 1.6 mm × 0.95 mm (L × W × H); cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener action |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| Low differential resistance | 80 Ω max ensures <10 mV output shift across 1–10 mA load variation in reference designs |
| Non-repetitive surge rating | 12 A peak reverse current enables single-event transient suppression without derating |
| Wide operating temperature | -55 °C to +150 °C ambient range supports under-hood and industrial control environments |
| Small outline package | SOD323F footprint saves >40 % board area vs. DO-35, enabling high-density layout in portable electronics |

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 MMBZ5235B | 6.8 V nominal, ±5 %, 100 Ω rdiff, SOT-23 package | Higher thermal resistance (300 K/W) reduces power handling on compact PCBs | Select when existing SOT-23 footprint must be retained; verify thermal margin at 550 mW |
| Vishay BZX84-C6V8 | 6.8 V nominal, ±5 %, 80 Ω rdiff, same SOD323F package but not AEC-Q101 qualified | Lacks automotive qualification; unsuitable for safety-critical vehicle subsystems | Use in cost-sensitive consumer electronics where AEC-Q101 is not mandated |
Compared with MMBZ5235B, BZX84J-C6V8,115 offers lower thermal resistance and automotive qualification; versus Vishay BZX84-C6V8, it adds AEC-Q101 compliance without sacrificing Zener performance or package compatibility.

FAQ
What is the maximum continuous Zener current for BZX84J-C6V8,115 at 25 °C ambient?
The device supports up to 250 mA forward current, but its continuous Zener operation is limited by power dissipation. At 25 °C ambient and mounted on FR4 with 1 cm² cathode pad, the maximum DC Zener current is 80.9 mA (550 mW ÷ 6.8 V), assuming ideal thermal conditions and no derating.
Does BZX84J-C6V8,115 require external series resistance in typical regulator applications?
Yes - a series current-limiting resistor is mandatory to set operating current within 1 mA to 20 mA range. For 12 V input and 6.8 V output at 5 mA, a 1.04 kΩ resistor (±1 %) ensures stable regulation while limiting power dissipation to 26 mW in the resistor.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With +1.2 mV/K coefficient at 5 mA, the Zener voltage shifts +102 mV from −40 °C to +125 °C (165 K delta), resulting in 6.8 V ±0.102 V drift. Combined with ±5 % initial tolerance, total worst-case error remains within ±0.44 V (±6.5 %) across full range.
Can BZX84J-C6V8,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient mismatch and cannot be reliably paralleled. Their dynamic resistance and thermal runaway risk make forced current sharing impractical; use a single higher-power Zener or active regulation instead.
