Product details
Overview
BZX884-C16,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 16 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 90 Ω typical differential resistance at 5 mA. It serves as a precision voltage reference or clamp in low-power analog signal conditioning and ESD protection circuits.
For engineers reviewing the BZX884-C16,315 datasheet, BZX884-C16,315 pinout, BZX884-C16,315 application, or BZX884-C16,315 equivalent, key selection criteria include Zener voltage tolerance, reverse leakage at operating bias, thermal resistance, junction temperature limit, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its 16 V nominal Zener voltage is specified at IZ = 5 mA with ±5 % tolerance, and exhibits a positive temperature coefficient of +12.4 mV/K at that test current.
The device features ultra-low capacitance (90 pF at 0 V, 1 MHz), supports non-repetitive peak reverse current up to 1.5 A (100 µs pulse), and is qualified per AEC-Q101 for automotive ambient temperature range (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.68 V to 16.32 V at IZ = 5 mA - defines stable regulation window under nominal bias |
| Differential Resistance (rdiff) | 50 Ω (max) at IZ = 5 mA - determines output impedance and regulation sensitivity to current change |
| Reverse Leakage (IR) | 50 nA max at VR = 11.2 V - ensures minimal quiescent current in standby clamp applications |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables low-loss forward conduction during transient overvoltage events |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling in standard layout |
| Junction Temperature (Tj) | 150 °C max - defines upper thermal limit for reliable long-term operation |
| Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies self-heating rise per watt in free-air mounting condition |
Pinout & Package
SOD882 (DFN1006-2) is a leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, with exposed copper pad for thermal conduction and cathode-marking 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 ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring extended temperature and reliability compliance |
| Ultra-small SOD882 footprint | Enables high-density PCB layouts in space-constrained modules such as sensor nodes and portable instrumentation |
| Low 90 pF capacitance at 0 V | Minimizes signal distortion in high-frequency clamping and RF-coupled protection paths up to ~100 MHz |
| ±5 % Zener voltage tolerance | Provides cost-optimized precision for non-critical voltage references where tighter tolerance is unnecessary |
| Non-repetitive surge capability | Withstands 1.5 A peak reverse current (100 µs pulse), supporting transient suppression in I/O line protection |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B16,315 | ±2 % Zener voltage tolerance (15.68–16.32 V unchanged), lower rdiff (50 Ω max vs. 200 Ω max), higher cost | Better regulation accuracy required in precision reference designs; less suitable for cost-sensitive clamping | Select when <1 % regulation error budget is mandatory and thermal derating margin permits tighter tolerance |
| MMSZ4687T1G | 16 V nominal, ±5 %, SOD-123 package (2.7 × 1.6 × 1.1 mm), 500 mW Ptot, 100 Ω rdiff max | Larger footprint and higher power handling; not AEC-Q101 qualified; higher thermal resistance (~300 K/W) | Choose for industrial non-automotive use where board space is less constrained and higher surge energy must be absorbed |
Compared with BZX884-C16,315, the BZX884-B16,315 offers tighter voltage control at the expense of cost and slightly reduced surge robustness, while MMSZ4687T1G trades automotive qualification and miniaturization for higher power capacity and legacy package compatibility.

FAQ
What is the maximum reverse voltage the BZX884-C16,315 can safely clamp before breakdown?
The BZX884-C16,315 begins controlled Zener breakdown at a minimum of 15.68 V (VZ min) under 5 mA test current. Its absolute maximum reverse voltage is limited by the 150 °C junction temperature and 250 mW power dissipation ceiling - sustained operation above 16.32 V will exceed rated power unless thermally managed.
Does the BZX884-C16,315 require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit reverse current to within the 250 mW power rating and prevent thermal runaway. For example, at 24 V supply and 16 V clamp, a minimum 32 Ω resistor limits current to 250 mA, staying within the 200 mA absolute maximum forward current rating.
How does the +12.4 mV/K temperature coefficient affect circuit performance?
The positive temperature coefficient means the Zener voltage increases by ~12.4 mV per degree Celsius rise in junction temperature. In bias networks, this can offset negative VBE drift in bipolar circuits; in precision references, it introduces ~1.2 % drift over a 100 °C range unless compensated.
Can the BZX884-C16,315 be used for bidirectional ESD protection?
No - it is a unidirectional Zener diode with defined anode and cathode terminals. For bidirectional ESD protection, two BZX884-C16,315 devices must be connected in series opposition (anode-to-anode), or a dedicated bidirectional TVS like PESD5V0S1BA should be selected instead.
