Product details
Overview
BZX884-B56,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 56 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 100 Ω typical differential resistance. It serves as a precision voltage reference or shunt regulator in low-power analog circuits, ESD protection clamps, and high-frequency bias networks.
For engineers reviewing the BZX884-B56,315 datasheet, BZX884-B56,315 pinout, BZX884-B56,315 application, or BZX884-B56,315 equivalent, this page delivers verified electrical parameters, thermal limits, AEC-Q101 qualification status, SOD882 footprint compatibility, and real-world use cases in automotive and industrial signal conditioning.
Technical Context
This Zener diode operates in reverse breakdown with a temperature coefficient of +57 mV/K at IZ = 5 mA, enabling stable regulation across −55 °C to +150 °C ambient range. Its 40 pF capacitance at 1 MHz and 0.9 V forward voltage at 10 mA support high-speed transient suppression and low-loss forward conduction paths.
Rated for non-repetitive peak reverse current up to 0.3 A (100 µs pulse), it meets AEC-Q101 stress requirements for automotive under-hood electronics. Thermal resistance from junction to ambient is 500 K/W on FR4 PCB with standard footprint, limiting continuous power handling at elevated temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 54.88 V to 57.12 V at IZ = 5 mA - defines precise clamping threshold for overvoltage protection |
| Differential Resistance (rdiff) | 100 Ω max at IZ = 5 mA - ensures minimal voltage shift under load current variation |
| Temperature Coefficient (SZ) | +57 mV/K typical at IZ = 5 mA - enables predictable drift compensation in temperature-critical references |
| Reverse Current (IR) | 50 nA max at VR = 39.2 V - guarantees low leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum steady-state thermal budget on standard FR4 PCB |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in automotive engine control and industrial motor drive environments |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - enables ultra-dense placement in space-constrained PCB layouts |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C56,315 | ±5% tolerance (53.2–58.8 V), higher max rdiff (200 Ω), same SOD882 package | Acceptable where cost sensitivity outweighs regulation precision; unsuitable for <1% reference designs | Select when BOM cost reduction is prioritized over voltage accuracy and thermal drift performance |
| MMSZ5255B-7-F | ±5% tolerance, SOD-123 package (2.7 × 1.6 × 1.1 mm), 500 mW Ptot, 110 Ω rdiff | Higher power handling but 3.5× larger footprint; incompatible with ultra-dense layouts | Choose only if board space permits larger package and higher continuous power is required |
Compared with BZX884-C56,315, the BZX884-B56,315 offers tighter voltage control and lower thermal drift for precision references; versus MMSZ5255B-7-F, it sacrifices power margin for 60% smaller PCB area and AEC-Q101 qualification.

FAQ
What is the maximum non-repetitive peak reverse current for BZX884-B56,315?
The maximum non-repetitive peak reverse current is 0.3 A at pulse duration tp = 100 µs and ambient temperature 25 °C, as specified in Table 5 of the datasheet. This rating supports IEC 61000-4-2 Level 4 ESD immunity testing when used in clamping configurations.
Is BZX884-B56,315 suitable for reflow soldering?
Yes - the SOD882 package is qualified for reflow soldering only, with recommended footprint dimensions provided in Figure 12. The device must be mounted on FR4 PCB using standard stencil-defined solder paste and IPC-J-STD-020-compliant thermal profiles.
How does the temperature coefficient affect regulation accuracy over temperature?
With a typical +57 mV/K coefficient at 5 mA, the Zener voltage increases ~3.2 V from −40 °C to +125 °C ambient. Designers must account for this 5.7% drift in precision references; pairing with negative-TC components can achieve net-zero drift in compensated circuits.
Can BZX884-B56,315 replace older Zener diodes in legacy designs?
Yes - its SOD882 footprint matches industry-standard DFN1006-2 land patterns, and electrical specs align with JEDEC JESD22-A108 reliability standards. However, verify thermal derating curves and layout copper area against original design margins before drop-in replacement.
