Product details
Overview
BZX384-C16,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 16 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 150 °C maximum junction temperature. It serves as a precision low-power voltage reference or shunt regulator in power supply feedback paths, sensor biasing circuits, and overvoltage protection clamps.
For engineers reviewing the BZX384-C16,115 datasheet, BZX384-C16,115 pinout, BZX384-C16,115 application, or BZX384-C16,115 equivalent, key selection considerations include its ±5 % VZ tolerance, 200 Ω typical differential resistance at IZ = 5 mA, 0.05 μA reverse current at VR = 12.8 V, 11.2 mV/K temperature coefficient, and SOD323 thermal resistance of 110 K/W to solder point.
Technical Context
This device operates in reverse-biased Zener breakdown mode with a nominal 16 V regulation voltage at 5 mA test current. Its ±5 % tolerance (BZX384-C series) targets cost-sensitive applications where tight regulation is secondary to stability and footprint efficiency.
Thermal design relies on low Rth(j-sp) = 110 K/W to cathode solder point and limits continuous dissipation to 300 mW at Tamb ≤ 25 °C on FR4 PCB. Non-repetitive surge capability supports 40 W peak reverse power for 100 μs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 16 V at IZ = 5 mA - defines stable regulation point for feedback or clamping |
| VZ tolerance | ±5 % - specifies allowable deviation from 16 V under production conditions |
| rdif | 200 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| IR | 0.05 μA max at VR = 12.8 V - quantifies leakage before breakdown onset |
| SZ | 11.2 mV/K - indicates how VZ drifts per degree Celsius change in junction temperature |
| Ptot | 300 mW - maximum continuous power dissipation on standard FR4 PCB at 25 °C ambient |
| IZSM | 1.5 A - non-repetitive peak reverse current for 100 μs surge events |
Pinout & Package
The BZX384-C16,115 is housed in a surface-mount SOD323 (SC-76) plastic package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode identified by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; establishes reference potential for breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD package | SOD323 footprint enables high-density PCB layouts without through-hole drilling |
| Controlled Zener voltage spread | ±5 % tolerance balances cost and performance for non-critical regulation tasks |
| Stable thermal interface | Rth(j-sp) = 110 K/W ensures predictable junction temperature rise above solder point |
| Robust surge handling | 40 W non-repetitive peak power rating supports transient overvoltage suppression |
| Low leakage performance | ≤0.05 μA at 80 % of VZ minimizes standby current in battery-powered systems |
Applications
| Power Supply Feedback | Sensor Biasing |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-derived DC-DC converters via optocoupler feedback loop. IC Role / Device Role / Timing Role: Shunt reference providing precise 16 V threshold to TL431-like control IC input. Use Value: Enables ±5 % output accuracy while maintaining compact size and low BOM count. |
Use Scenario: Providing stable bias voltage to analog sensor elements such as RTDs or bridge-based pressure transducers. IC Role / Device Role / Timing Role: Low-drift voltage reference sourcing constant current into sensor excitation path. Use Value: Delivers 16 V ±5 % with <12 mV/K tempco, reducing measurement offset drift across industrial temperature range. |
| Overvoltage Clamp | Microcontroller I/O Protection |
Use Scenario: Protecting downstream 16 V-rated circuitry from transient surges exceeding 18 V. IC Role / Device Role / Timing Role: Fast-acting shunt limiter diverting excess energy to ground during ESD or load-dump events. Use Value: Absorbs up to 40 W for 100 μs without failure, limiting clamped voltage to ≤17.6 V (110 % of VZ). |
Use Scenario: Safeguarding 3.3 V or 5 V microcontroller GPIO pins against accidental 12–16 V miswiring or backfeed. IC Role / Device Role / Timing Role: Bidirectional clamp (with series resistor) limiting pin voltage to safe levels during fault conditions. Use Value: Leverages low 200 Ω rdif to hold clamped voltage within 0.5 V of VZ, preventing latch-up or oxide damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F | 16 V nominal, ±5 %, SOT-323 package, 200 mW Ptot, higher rdif (300 Ω) | Lower power rating reduces thermal margin in sustained regulation use | Select when legacy SOT-323 footprint compatibility is required over thermal performance |
| BZX384-B16,115 | Same SOD323 package and 16 V nominal, but ±2 % tolerance and lower rdif (150 Ω) | Tighter tolerance improves regulation accuracy in precision feedback loops | Choose for applications demanding better than ±5 % VZ stability without changing layout |
Compared with BZX384-C16,115, MMBZ5245BS-7-F offers identical voltage grade but reduced power handling and higher impedance, while BZX384-B16,115 delivers tighter tolerance and lower dynamic resistance-making it preferable for accuracy-critical regulation where cost premium is acceptable.

FAQ
What is the maximum continuous reverse current the BZX384-C16,115 can sustain?
The device is rated for 250 mA maximum forward current, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 16 V, the absolute maximum continuous reverse current is 18.75 mA (300 mW ÷ 16 V), assuming full derating at 25 °C ambient and no thermal margin.
Does the BZX384-C16,115 meet automotive qualification standards?
No. Per Nexperia's revision history, the BZX384 series was changed to non-automotive qualification in Rev. 4 (January 2023). Automotive-grade alternatives are designated with "-Q" suffixes and require separate part numbers and qualification documentation.
How does the 11.2 mV/K temperature coefficient affect regulation accuracy over temperature?
At a 125 °C junction temperature rise (e.g., from 25 °C to 150 °C), VZ shifts by +1.4 V (11.2 mV/K × 125 K), resulting in a 17.4 V regulation point-within the ±5 % band's upper limit of 16.8 V only if initial VZ is at minimum spec (15.3 V). Designers must account for this drift in wide-temperature applications.
Can the BZX384-C16,115 be used in series or parallel configurations?
Series connection is feasible for higher voltage references but requires matched units to avoid current imbalance. Parallel use is strongly discouraged due to negative temperature coefficient interaction and unequal current sharing, which risks thermal runaway and premature failure.
