Product details
Overview
BZX84J-C5V1/DG/B2 from Nexperia is a 5.1 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 150 °C junction temperature, with low differential resistance (480 Ω at IZ = 5 mA) and AEC-Q101 qualification for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX84J-C5V1 datasheet, BZX84J-C5V1 pinout, BZX84J-C5V1 application, or BZX84J-C5V1 equivalent, this device serves as a precision shunt regulator in low-power supply rails, ESD-clamped signal conditioning paths, and biasing networks where stable reverse breakdown voltage and thermal robustness are required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 5.1 V reference across its terminals under controlled current conditions (IZ = 5 mA). Its differential resistance of 480 Ω ensures minimal voltage deviation with load current changes, while the −2.7 to +1.2 mV/K temperature coefficient enables predictable drift behavior over −55 °C to +150 °C ambient range.
The device supports non-repetitive surge handling up to 40 W (100 µs square wave, Tj = 25 °C prior to surge) and exhibits ≤ 2 µA reverse leakage at VR = 1 V, making it suitable for transient-suppressed regulation in space-constrained automotive and industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.80 V to 5.40 V at IZ = 5 mA - defines stable regulation point for 5 V rail clamping |
| Tolerance | ±5 % - allows predictable design margin without trimming in cost-sensitive applications |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdiff) | 480 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | ≤ 2 µA at VR = 1 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C maximum - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2-terminal, ultra-small outline (2.3 mm × 1.35 mm × 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 |
| 2 (A) | Anode | Connected to ground or lower-potential reference; current flows anode-to-cathode in forward bias |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 480 Ω at 5 mA - improves regulation accuracy under varying load currents |
| AEC-Q101 qualification | Validated for automotive use - eliminates need for additional qualification testing in Tier-1 designs |
| Non-repetitive peak power | 40 W (100 µs pulse) - withstands common ESD and load-dump transients without degradation |
| Wide operating temperature | −55 °C to +150 °C - supports under-hood, engine control, and industrial sensor modules |
| Small SMD footprint | SOD323F (SC-90) - saves board area in dense power management and interface circuits |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; Ptot = 365 mW | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial harsh environments | Select only when AEC-Q101 is not required and board layout allows higher thermal resistance |
| MMSZ5231B | 5.1 V ±5 %, SOD-123 package, Ptot = 500 mW, rdiff = 17 Ω (lower), no AEC-Q101 | Better regulation accuracy but lacks automotive qualification and has larger footprint (3.7 mm × 1.6 mm) | Prefer for high-precision lab equipment where thermal margin exists and qualification is secondary |
Compared with BZX84-C5V1 and MMSZ5231B, the BZX84J-C5V1 uniquely combines AEC-Q101 qualification, 550 mW power rating, and ultra-compact SOD323F packaging-making it the only option for space-constrained, thermally demanding automotive voltage references requiring production-grade reliability.

FAQ
What is the maximum continuous reverse current for BZX84J-C5V1 at 25 °C?
The device is rated for continuous Zener current up to 100 mA (derived from Ptot = 550 mW and VZ ≈ 5.1 V), though typical regulation uses 5 mA to 20 mA for optimal stability and thermal performance. Absolute maximum forward current is 250 mA per limiting values table.
Can BZX84J-C5V1 be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated Zener or implement active regulation with a transistor-based shunt.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-Nexperia specifies reflow soldering as the only recommended method, with peak temperature up to 260 °C (per JEDEC J-STD-020). The SC-90 footprint in Figure 12 provides exact pad dimensions and solder paste stencil recommendations for reliable assembly.
How does the −2.7 to +1.2 mV/K temperature coefficient affect regulation accuracy over temperature?
At 5.1 V nominal, this coefficient yields ±0.15 V drift over −40 °C to +125 °C operating range-within acceptable limits for non-precision references. For tighter stability, pair with a complementary positive-TC component or use temperature-compensated Zener alternatives like BZX84-J series variants with tighter SZ specs.
