Product details
Overview
BZX84J-B8V2,115 from Nexperia is a ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 8.2 V nominal regulation voltage at 5 mA, with 550 mW total power dissipation and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84J-B8V2,115 datasheet, BZX84J-B8V2,115 pinout, BZX84J-B8V2,115 application, or BZX84J-B8V2,115 equivalent, this device serves as a precision voltage reference or overvoltage clamp in low-power analog circuits, ESD-protected interfaces, and automotive sensor signal conditioning where tight tolerance and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its differential resistance of 80 Ω at 5 mA ensures minimal output voltage variation with current changes, while its positive temperature coefficient of +3.2 mV/K at 5 mA enables predictable drift compensation in bias networks.
The device supports pulsed non-repetitive surge handling up to 40 W (100 µs square wave), and its 150 °C maximum junction temperature rating allows reliable operation in under-hood automotive environments. Thermal resistance from junction to ambient is 230 K/W on standard FR4 PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 8.2 V at IZ = 5 mA - precise regulation point for reference or clamping |
| Tolerance | ±2 % - tighter than standard ±5 % variants, enabling higher-accuracy voltage setting |
| Differential Resistance | 80 Ω at IZ = 5 mA - low impedance ensures stable output under small load variations |
| Temperature Coefficient | +3.2 mV/K at IZ = 5 mA - predictable positive drift aids thermal compensation design |
| Total Power Dissipation | 550 mW at Tamb ≤ 25 °C - defines continuous DC power limit on standard PCB layout |
| Non-repetitive Peak Power | 40 W (100 µs, square wave) - supports transient overvoltage suppression without failure |
| Reverse Current @ 7.5 V | ≤ 0.7 µA - ensures low leakage before breakdown, critical for high-impedance bias networks |
Pinout & Package
Package: SOD323F (SC-90), ultra-compact surface-mount plastic package with flat leads; dimensions 2.7 × 1.35 × 0.95 mm; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage node; marking bar identifies this terminal |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Low differential resistance | 80 Ω enables <10 mV output shift per 0.1 mA load change - critical for precision references |
| Stable temperature coefficient | +3.2 mV/K allows predictable drift modeling in wide-temperature-range designs (−55 °C to +150 °C) |
| Small SOD323F footprint | 2.7 × 1.35 mm area saves board space in dense automotive ECUs and portable electronics |
| Low leakage current | ≤ 0.7 µA at 7.5 V ensures minimal error in high-impedance voltage divider or bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,115 | ±5 % tolerance (vs. ±2 %); same 8.2 V nominal, SOD323F package, 40 W surge rating | Lower accuracy acceptable in non-critical biasing or coarse clamping where cost sensitivity outweighs precision | Select when budget constraints dominate and ±5 % voltage variation is tolerable in system margin analysis |
| MMSZ5234B-7-F | ±5 % tolerance; 8.2 V nominal; SOD-123 package (larger, 3.7 × 1.6 mm); 500 mW Ptot | Less space-constrained layouts; slightly lower thermal resistance (200 K/W vs. 230 K/W) but no AEC-Q101 qualification | Choose for industrial non-automotive designs requiring marginally better thermal performance and no automotive compliance requirement |
Compared with BZX84J-B8V2,115, the BZX84-C8V2,115 trades precision for cost in identical form factor, while MMSZ5234B-7-F offers modest thermal improvement at the expense of automotive qualification and board space - making the BZX84J-B8V2,115 optimal for space-limited, thermally demanding, and safety-critical automotive voltage references.

FAQ
What is the maximum continuous forward current for BZX84J-B8V2,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; it is designed for reverse-bias Zener regulation. Continuous forward operation above 100 mA risks exceeding junction temperature limits due to VF ≈ 1.1 V at that current, leading to thermal runaway if not heatsinked.
Does BZX84J-B8V2,115 support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's documentation. Hand-soldering is not advised due to the SOD323F package's small thermal mass and sensitivity to localized overheating; excessive iron tip dwell time (>3 s at >300 °C) may damage the die or delaminate the molding compound.
How does the ±2 % tolerance affect regulation accuracy across temperature?
At 25 °C, ±2 % means 8.04–8.36 V; combined with +3.2 mV/K TC, worst-case drift over −40 °C to +150 °C adds ±0.608 V, yielding a total range of ~7.43–9.0 V. This remains within typical 10 % system margin for automotive sensor bias rails.
Is the cathode marking bar visible under standard optical inspection?
Yes - the cathode is marked by a distinct white or light-colored bar on the top surface of the SOD323F package, aligned with pin 1 per Figure 11. This marking is laser-etched or molded and clearly identifiable using 10× magnification or automated AOI systems calibrated for SC-90 packages.
