Product details
Overview
BZX884-B2V4,315 from Nexperia is a 2.4 V ±2 % Zener voltage regulator diode in an ultra-compact SOD882 (DFN1006-2) surface-mount package, rated for 250 mW total power dissipation and 200 mA maximum forward current, used for precision low-voltage regulation and ESD protection in space-constrained consumer and automotive electronics.
For engineers reviewing the BZX884-B2V4,315 datasheet, BZX884-B2V4,315 pinout, BZX884-B2V4,315 application, or BZX884-B2V4,315 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low differential resistance (275 Ω at 1 mA), temperature coefficient (−1.3 mV/K), junction-to-ambient thermal resistance (500 K/W), and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 2.4 V regulation at IZ = 5 mA, with typical reverse current <3 µA at VR = 1 V and forward voltage ≤0.9 V at IF = 10 mA. Its low capacitance (450 pF at f = 1 MHz, VR = 0 V) supports high-frequency transient suppression.
The device features a negative temperature coefficient of −1.3 mV/K at IZ = 5 mA, enabling predictable voltage drift over temperature, and is qualified to AEC-Q101 for automotive underhood applications with Tj up to 150 °C and Tamb from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V nominal, ±2 % tolerance (2.35–2.45 V at IZ = 5 mA) - ensures tight regulation in low-voltage bias and reference circuits |
| Differential Resistance (rdiff) | 275 Ω max at IZtest = 1 mA - maintains stable output under small-signal load variations |
| Temperature Coefficient (SZ) | −1.3 mV/K at IZ = 5 mA - enables predictable voltage drift compensation in temperature-sensitive designs |
| Reverse Current (IR) | 50 µA max at VR = 1 V - minimizes leakage in standby and battery-powered systems |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - reduces conduction loss in series-clamp or dual-direction protection configurations |
| Package Dimensions | 1.0 × 0.6 × 0.5 mm (SOD882/DFN1006-2) - enables placement in 0402-class footprints for ultra-dense PCB layouts |
| Non-repetitive Peak Reverse Current (IZSM) | 6 A at tp = 100 µs - provides robust ESD immunity per IEC 61000-4-2 Level 4 (±15 kV air) |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small plastic surface-mount package with two terminals, body size 1.0 mm × 0.6 mm × 0.5 mm, and a cathode-marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed for correct Zener operation and ESD clamping direction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for voltage regulation and transient absorption |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood use with extended temperature cycling, humidity, and mechanical stress testing |
| Ultra-small SOD882 footprint | Enables placement in high-density mobile and wearables PCBs where board area is constrained to <0.6 mm² per device |
| 250 mW power rating | Supports continuous regulation in low-power sensor biasing and reference supply applications without forced cooling |
| Low 450 pF junction capacitance | Minimizes signal distortion in RF front-end ESD protection and high-speed data line clamping (e.g., USB 2.0, I²C) |
| ±2 % Zener tolerance | Reduces binning requirements and improves yield in precision voltage reference designs requiring <50 mV absolute error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation and ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | 2.4 V ±5 % tolerance, SOT-323 package (2.0 × 1.25 × 0.95 mm), 350 mW Ptot | Larger footprint and looser tolerance; higher power but less suitable for ultra-dense layouts | Select when higher surge handling is needed and board area permits larger package |
| BZX384-B2V4 | Same 2.4 V ±2 % spec, but SOD323 package (1.7 × 1.3 × 0.9 mm), 300 mW Ptot, non-AEC-Q101 | Higher power rating but lacks automotive qualification and has 2.8× larger footprint | Select for industrial non-automotive applications requiring slightly higher dissipation without AEC compliance |
Compared with BZX884-B2V4,315, MMBZ5221BS-7-F trades compactness and tight tolerance for higher surge capacity, while BZX384-B2V4 offers more power in a larger, non-automotive-qualified package-making the BZX884-B2V4,315 optimal for AEC-Q101-compliant, space-constrained designs needing ±2 % stability.

FAQ
What is the maximum reverse voltage this diode can withstand continuously?
The BZX884-B2V4,315 is rated for continuous reverse operation at its nominal Zener voltage of 2.4 V. Its absolute maximum limiting value is defined by power dissipation: at 25 °C ambient, it may sustain up to 250 mW, corresponding to ~104 mA at 2.4 V. Exceeding this causes thermal runaway and permanent failure.
Is this diode suitable for bidirectional ESD protection?
No - the BZX884-B2V4,315 is a unidirectional Zener diode configured as a cathode-grounded shunt regulator. For bidirectional ESD protection, two devices must be connected anode-to-anode or a dedicated TVS array like PESD5V0S1BA must be used.
How does the ±2 % tolerance affect circuit performance in a 2.4 V reference design?
At 2.4 V nominal, ±2 % tolerance means the actual Zener voltage falls between 2.35 V and 2.45 V at 5 mA test current. This introduces up to ±20.8 mV absolute error in reference outputs, requiring calibration or trimming in high-accuracy ADC biasing applications.
Can this diode replace a 2.4 V Zener in a linear regulator feedback network?
Yes - its tight ±2 % tolerance, low rdiff (275 Ω), and stable −1.3 mV/K temperature coefficient make it suitable for feedback references in low-current LDOs, provided the regulator's feedback divider ratio and load current remain within the diode's 250 mW dissipation limit.
