Product details

Overview

BZX884-C11,315 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 11 V nominal regulation at 5 mA, with 250 mW total power dissipation and 100 nA reverse leakage at 8 V. It delivers stable voltage reference and overvoltage clamping in space-constrained consumer and industrial power rails.

For engineers reviewing the BZX884-C11,315 datasheet, BZX884-C11,315 pinout, BZX884-C11,315 application, or BZX884-C11,315 equivalent, this page provides verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance data - all confirmed from Nexperia's official Rev. 5 product data sheet.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 11 V reference across load variations, with a typical differential resistance of 25 Ω at 5 mA test current and a positive temperature coefficient of +6.9 mV/K. Its ultra-small DFN1006-2 footprint enables high-density PCB layouts without compromising thermal performance.

Designed for surface-mount use on FR4 boards with standard solder paste stencil, it supports AEC-Q101 qualification and exhibits 150 °C maximum junction temperature, 500 K/W junction-to-ambient thermal resistance, and non-repetitive peak reverse current capability up to 2.5 A for transient suppression.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	10.78 V to 11.22 V at I_Z = 5 mA - defines precise regulation window for 11 V rail stabilization
Differential Resistance (r_diff)	25 Ω (typ) at I_Z = 5 mA - determines output impedance and load regulation sensitivity
Temperature Coefficient (S_Z)	+6.9 mV/K at I_Z = 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature
Reverse Leakage (I_R)	100 nA max at V_R = 8 V - ensures minimal quiescent current in standby or low-power modes
Total Power Dissipation (P_tot)	250 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB
Forward Voltage (V_F)	0.9 V max at I_F = 10 mA - defines conduction loss when used in forward-biased ESD protection paths
Junction-to-Ambient R_th	500 K/W - establishes thermal derating requirement for ambient temperature increases

Pinout & Package

SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, tin-plated copper terminals, cathode marked by bar on top surface.

Pin/Terminal	Circuit Role	Design Meaning
1	Cathode (K)	Connected to regulated output node; reverse-bias anode-to-cathode voltage triggers Zener conduction
2	Anode (A)	Connected to ground or lower-potential reference; completes current path during regulation or clamping

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock
±5% Zener voltage tolerance	Enables cost-optimized selection where tight regulation is not required, e.g., non-critical biasing or coarse clamping
Ultra-small DFN1006-2 footprint	Reduces board area by >60% vs. SOD-123, supporting miniaturized wearables and IoT sensor nodes
250 mW power rating	Supports sustained 11 V regulation at up to ~22.7 mA (250 mW / 11 V), sufficient for low-current references
100 nA reverse leakage at 8 V	Minimizes standby current in battery-powered systems where leakage directly impacts shelf life

Applications

Power Rail Clamping

Reference Voltage Source

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX884-B11,315	±2% tolerance (10.78–11.22 V same, but tighter distribution), 25 Ω r_diff, +6.9 mV/K S_Z	Higher precision needed for ADC references or feedback loops requiring <0.2% voltage stability	Select when tighter initial tolerance justifies higher unit cost and inventory complexity
MMSZ5240B-7-F	10 V nominal, ±5%, SOD-123 package (2.7 × 1.4 mm), 500 mW P_tot, 17 Ω r_diff	Higher power handling and larger footprint acceptable; requires layout redesign for compatibility	Choose when board space allows larger package and 500 mW dissipation is required for higher-current regulation

Compared with BZX884-C11,315, the BZX884-B11,315 offers improved initial accuracy but identical thermal and dynamic characteristics, while MMSZ5240B-7-F trades miniaturization for higher power and lower impedance - making each suitable for distinct trade-offs between size, precision, and thermal margin.

FAQ

What is the maximum continuous reverse current the BZX884-C11,315 can handle at 25 °C ambient?

The device has no specified maximum continuous reverse current rating; its operation is defined by power dissipation limits. At 25 °C ambient and 11 V Zener voltage, the maximum continuous reverse current is 22.7 mA (250 mW ÷ 11 V), assuming no thermal derating. Exceeding this draws power beyond P_tot, risking thermal runaway.

Does the BZX884-C11,315 support reflow soldering only, or can it be hand-soldered?

Reflow soldering is the only recommended process per Nexperia's documentation. Hand-soldering is not advised due to the DFN1006-2 package's small pitch (0.55 mm), thermal mass constraints, and risk of pad lifting or voiding. Reflow profiles must follow JEDEC J-STD-020 guidelines for MSL1 components.

How does the +6.9 mV/K temperature coefficient affect regulation accuracy over temperature?

At 11 V nominal, a +6.9 mV/K coefficient causes +0.69 V drift over a 100 K rise (e.g., −40 °C to +60 °C ambient). Combined with ±5% initial tolerance, total variation reaches ±0.55 V + 0.69 V = ±1.24 V, or ±11.3% full scale - critical for precision references but acceptable for clamping or coarse biasing.

Is the SOD882 package compatible with automated optical inspection (AOI) systems?

Yes - the SOD882 package features a visible cathode marking bar and coplanar terminations, enabling reliable AOI detection of solder joint quality, polarity, and placement accuracy. Its 0.6 mm width and 1.0 mm length fall within standard AOI resolution thresholds for 10 µm pixel cameras.
