Product details
Overview
BZX884-C56,315 from Nexperia is a ±5% tolerance Zener diode with 56 V nominal regulation voltage, 250 mW total power dissipation, and ultra-small SOD882 (DFN1006-2) package. It operates as a precision voltage reference or clamp in low-power analog circuits, ESD protection paths, and high-frequency signal conditioning stages.
For engineers reviewing the BZX884-C56,315 datasheet, BZX884-C56,315 pinout, BZX884-C56,315 application, or BZX884-C56,315 equivalent, key selection criteria include Zener voltage tolerance, differential resistance at 2 mA, temperature coefficient, reverse leakage at 0.7×VZ, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode delivers stable 56 V regulation at IZ = 2 mA with typical differential resistance of 100 Ω and temperature coefficient of +57.0 mV/K. Its low 40 pF capacitance at 1 MHz and VR = 0 V supports high-frequency decoupling and transient suppression up to ~100 MHz.
The device features AEC-Q101 qualification, 150 °C maximum junction temperature, and 0.9 V forward voltage at IF = 10 mA. Its SOD882 footprint enables placement in space-constrained PCB layouts while maintaining thermal performance under FR4 board conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 56 V nominal at IZ = 2 mA; ±5% tolerance ensures regulation within 53.2–58.8 V across production lot |
| Differential Resistance (rdiff) | 100 Ω max at IZtest = 2 mA; limits output impedance drift during load transients |
| Temperature Coefficient (SZ) | +57.0 mV/K typical at IZ = 2 mA; positive drift compensates for ambient cooling in sealed enclosures |
| Reverse Leakage (IR) | 50 nA max at VR = 39.2 V (0.7 × VZ); enables low-quiescent-current bias networks |
| Capacitance (Cd) | 40 pF max at f = 1 MHz, VR = 0 V; preserves signal integrity in RF coupling and ESD clamping paths |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB; defines maximum continuous DC or pulsed power handling |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; supports low-loss anode-side current limiting in series regulator configurations |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, 2-terminal surface-mount design with cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to reference or ground potential; reverse-biased operation requires this terminal at lower potential than cathode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use including engine control modules and ADAS sensor interfaces |
| Ultra-small SOD882 footprint | Enables placement in <1.0 mm² board area; compatible with 0201-class reflow profiles and automated optical inspection |
| ±5% Zener voltage tolerance | Provides cost-optimized regulation accuracy for non-critical biasing and overvoltage clamping functions |
| Low 40 pF junction capacitance | Minimizes signal attenuation in >50 MHz RF detector and antenna matching applications |
| 150 °C maximum junction temperature | Supports operation in under-hood automotive environments and thermally dense industrial PCBs |

| High-Frequency RF Detector | Industrial PLC Analog Input Protection |
Use Scenario: Rectifying and regulating RF envelope signals in 900 MHz ISM-band receiver front-ends. IC Role / Device Role / Timing Role: Zener diode serves as self-biasing detector element, converting RF peaks into DC voltage proportional to signal amplitude. Use Value: Low 100 Ω dynamic resistance ensures linear response across 2–10 mA detection current range without distortion. |
Use Scenario: Protecting 0–10 V analog input channels of programmable logic controllers against field-wiring faults and lightning-induced surges. IC Role / Device Role / Timing Role: Shunt regulator clamps input voltage to 56 V, preventing damage to downstream op-amps and ADC drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B56,315 | ±2% tolerance (54.88–57.12 V), 70 Ω rdiff max at 2 mA, +57.0 mV/K SZ | Higher regulation accuracy required for precision reference designs; tighter thermal drift control | Select when voltage stability over temperature and unit-to-unit variation must be minimized |
| MMSZ5256B-7-F | ±5% tolerance (53.2–58.8 V), 110 Ω rdiff max at 20 mA, +52 mV/K SZ, SOD-123 package (2.7 × 1.6 mm) | Larger footprint; higher test current shifts operating point; less suitable for high-density layouts | Choose only if legacy SOD-123 footprint compatibility is mandatory and board area is unconstrained |
Compared with BZX884-B56,315, the C-grade offers relaxed tolerance for cost-sensitive applications without sacrificing AEC-Q101 compliance or thermal robustness; versus MMSZ5256B-7-F, it delivers 45% smaller board area and superior high-frequency performance due to lower capacitance and optimized geometry.

FAQ
What is the maximum reverse voltage the BZX884-C56,315 can sustain continuously?
The device is rated for continuous reverse operation up to its nominal Zener voltage of 56 V at IZ = 2 mA. Absolute maximum reverse voltage is not specified separately; operation beyond 56 V must remain within the 250 mW power limit and 150 °C junction temperature constraint, with derating applied above 25 °C ambient.
Does the SOD882 package require special soldering profile considerations?
Yes - the SOD882 package is qualified for reflow soldering only, with peak temperature limited to 260 °C for ≤10 seconds. The recommended footprint uses 0.3 mm wide solder lands with 0.6 mm spacing; thermal relief patterns must avoid excessive copper pour that impedes heat dissipation during reflow.
How does the +57.0 mV/K temperature coefficient affect circuit performance?
This positive coefficient means the Zener voltage increases by approximately 57 mV per Kelvin rise in junction temperature. In circuits where ambient temperature varies widely, this drift must be compensated in feedback loops or accounted for in tolerance budgets - especially critical in precision reference and sensor excitation applications.
Can BZX884-C56,315 replace BZX884-B56,315 in existing designs?
Yes, mechanically and electrically - both share identical SOD882 package, pinout, power rating, and thermal specifications. The only functional difference is tighter ±2% voltage tolerance in the B-grade. Substitution is acceptable where 5% regulation accuracy meets system requirements and no recalibration is needed.
