Product details
Overview
BZX84J-B5V6/DG/B2 from Nexperia is a 5.6 V ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 12 A non-repetitive peak reverse current at 100 µs pulse width, used for precision voltage regulation and overvoltage protection in automotive and industrial power rails.
For engineers reviewing the BZX84J-B5V6/DG/B2 datasheet, BZX84J-B5V6/DG/B2 pinout, BZX84J-B5V6/DG/B2 application, or BZX84J-B5V6/DG/B2 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (400 Ω at IZ = 1 mA), AEC-Q101 qualification, thermal resistance (230 K/W junction-to-ambient), and SC-90 package compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 5.6 V reference across load variations, with low differential resistance (400 Ω at 1 mA) ensuring minimal voltage drift under dynamic current conditions. Its temperature coefficient of −2.0 to +2.5 mV/K at IZ = 5 mA enables predictable thermal behavior in ambient ranges from −55 °C to +150 °C.
The device supports pulsed surge handling up to 100 W (for ≤6.8 V types) with tp ≤ 100 µs square-wave pulses, and features low reverse leakage (<1 µA at VR = 2 V) and 275 pF capacitance at 1 MHz/0 V, making it suitable for noise-sensitive regulation nodes adjacent to analog or RF circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - tight ±2 % tolerance ensures accurate 5.6 V reference for feedback loops in DC-DC converters. |
| Differential Resistance (rdiff) | 400 Ω at IZ = 1 mA - low impedance stabilizes output voltage against small-signal load transients. |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB with 1 cm² cathode pad. |
| Non-repetitive Peak Reverse Current (IZSM) | 12 A at tp = 100 µs - supports transient overvoltage clamping without failure in automotive load-dump scenarios. |
| Reverse Leakage Current (IR) | ≤1 µA at VR = 2 V - minimizes quiescent current loss in battery-powered standby circuits. |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments and industrial control enclosures. |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including HTOL, temperature cycling, and ESD testing per AEC stress requirements. |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.3 mm × 1.35 mm footprint, 0.65 mm height, flat lead profile optimized for reflow soldering and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar on package identifies this terminal for correct polarity orientation during layout. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener breakdown conduction when VR > VZ. |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 400 Ω at IZ = 1 mA - reduces output voltage variation under changing load current, critical for stable feedback references. |
| AEC-Q101 qualification | Qualified per Automotive Electronics Council standard - assures long-term reliability in automotive power management systems. |
| Small SOD323F package | 2.3 mm × 1.35 mm footprint - enables high-density routing in space-constrained modules like ADAS ECUs and body control units. |
| Wide operating temperature range | −55 °C to +150 °C - supports deployment in engine compartments and industrial motor drives without derating. |
| Pulsed surge capability | 100 W non-repetitive peak power (tp ≤ 100 µs) - provides robust transient suppression for ISO 7637-2 compliant automotive electronics. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Reference Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | ±5 % tolerance (vs. ±2 %), higher rdiff (480 Ω), same SOD323F package and AEC-Q101 status | Acceptable where tighter regulation not required; lower cost for consumer-grade power supervision | Select for cost-sensitive non-automotive designs where 5.32–5.88 V range is sufficient. |
| MMSZ5232B | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint), no AEC-Q101 qualification | Limited to commercial/industrial use; incompatible with high-density automotive layouts due to 3.7 mm × 1.6 mm size | Choose only if SOD-123 is already standardized in legacy designs and automotive qualification is unnecessary. |
Compared with BZX84J-B5V6/DG/B2, the BZX84-C5V6 offers lower cost but sacrifices 2.5× tighter voltage tolerance and slightly higher impedance, while MMSZ5232B trades AEC-Q101 compliance and board area efficiency for broader distributor availability in non-automotive contexts.

FAQ
What is the maximum continuous forward current for BZX84J-B5V6/DG/B2?
The absolute maximum forward current (IF) is 250 mA per limiting values table. However, sustained forward conduction is not its intended operating mode; the device is designed for reverse-bias Zener regulation. Forward voltage is specified at 100 mA (VF ≤ 1.1 V), but continuous forward operation above 10 mA risks thermal overstress due to low thermal resistance design optimized for reverse breakdown.
Does BZX84J-B5V6/DG/B2 require external series resistance in regulation circuits?
Yes - a current-limiting resistor is mandatory to set nominal Zener current (typically 5 mA for BZX84J-B5V6). Without it, excessive current causes thermal runaway. For a 12 V input, a 1.2 kΩ resistor delivers ~5.3 mA, aligning with the 5 mA test condition used for VZ and rdiff specifications in the datasheet.
How does the −2.0 to +2.5 mV/K temperature coefficient affect regulation accuracy?
This coefficient indicates VZ changes by up to ±2.5 mV per °C rise from 25 °C. Over a −40 °C to +125 °C range, total drift is ≤±413 mV - acceptable for non-precision references. For tighter stability, pair with a thermistor-compensated network or select a 6.2 V type (BZX84J-B6V2) with near-zero coefficient (0.4 to 3.7 mV/K).
Can BZX84J-B5V6/DG/B2 replace BZX84-C5V6 in existing designs?
Yes, mechanically and electrically - both share identical SOD323F package, pinout, and thermal characteristics. The primary difference is ±2 % vs. ±5 % VZ tolerance. If the original design accommodates 5.32–5.88 V (±5 %), the BZX84J-B5V6/DG/B2 improves regulation accuracy to 5.49–5.71 V but may require validation of downstream voltage margins.
