Product details
Overview
BZX384-C13,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 13 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 150 °C maximum junction temperature. It provides stable reference voltage in low-power analog circuits, power supply feedback paths, and overvoltage protection for microcontroller I/O pins.
For engineers reviewing the BZX384-C13,115 datasheet, BZX384-C13,115 pinout, BZX384-C13,115 application, or BZX384-C13,115 equivalent, key selection criteria include its 13 V ±5 % Zener voltage tolerance, 170 Ω max differential resistance at 5 mA, 30 μA max reverse current at 10.4 V, and thermal resistance of 415 K/W in free air - all critical for precision biasing and compact PCB layout.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable DC reference voltage across its terminals under varying load and temperature conditions. Its design targets low-current regulation (IZ = 5 mA typical), with specified performance at Tj = 25 °C and validated up to 150 °C junction temperature.
The device exhibits a positive temperature coefficient of +7.0 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references. Its 170 Ω maximum differential resistance ensures minimal output impedance variation over operating current range, supporting consistent regulation in feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4 V to 14.1 V at IZ = 5 mA - defines usable regulation window for 13 V nominal reference |
| Differential Resistance (rdif) | ≤170 Ω at IZ = 5 mA - limits output impedance variation under load changes |
| Reverse Current (IR) | ≤30 μA at VR = 10.4 V - ensures low leakage before breakdown onset |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments |
| Thermal Resistance (Rth(j-a)) | 415 K/W in free air - determines temperature rise per watt dissipated without heatsinking |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - enables transient overvoltage clamping capability |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, cathode-marked with bar, 2.7 mm × 1.6 mm footprint, 0.45 mm nominal height, optimized for reflow soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; reverse-bias anode-to-cathode voltage establishes Zener conduction |
| 2 (A) | Anode | Typically grounded or connected to lower-potential rail; completes reverse-bias path for regulation current flow |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., non-critical biasing or coarse overvoltage detection |
| 300 mW power rating | Supports regulation in low-current signal chains (<25 mA) without external heatsinking on standard PCBs |
| 170 Ω max differential resistance | Minimizes output voltage shift under ±1 mA load variation, improving stability in feedback loops |
| +7.0 mV/K temperature coefficient | Provides predictable, linear VZ drift with temperature - useful for compensated reference designs |
| 40 W non-repetitive peak power | Allows clamping of short-duration transients (e.g., ESD or inductive spikes) without failure |
Applications
| Power Supply Feedback | Microcontroller I/O Protection |
|---|---|
Use Scenario: Regulating output voltage in low-power AC/DC adapter feedback network using optocoupler-coupled TL431 alternative. IC Role / Device Role / Timing Role: Zener diode provides fixed 13 V reference to error amplifier input, setting output regulation threshold. Use Value: Delivers stable reference despite ±5 % tolerance due to closed-loop compensation; 300 mW rating avoids thermal derating in space-constrained adapters. |
Use Scenario: Clamping 3.3 V GPIO lines against 12 V supply faults in industrial sensor interface boards. IC Role / Device Role / Timing Role: Acts as shunt overvoltage protector, conducting excess current when line exceeds 13 V. Use Value: 40 W surge rating absorbs 100 μs transients; SOD323 footprint minimizes board area vs. through-hole alternatives. |
| Reference Voltage Source | Signal Level Shifting |
Use Scenario: Generating precise 13 V bias for op-amp comparator hysteresis in battery monitoring circuit. IC Role / Device Role / Timing Role: Supplies stable reference to comparator non-inverting input, defining trip point. Use Value: +7.0 mV/K TC allows predictable offset adjustment; 170 Ω rdif ensures <10 mV shift under 50 μA load variation. |
Use Scenario: Translating 5 V logic signals to 13 V level for driving legacy industrial actuators. IC Role / Device Role / Timing Role: Configured in series with current-limiting resistor to clamp high-side signal to 13 V. Use Value: Low 0.9 V forward voltage at 10 mA enables efficient level-up conversion; SOD323 enables dense routing near connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-C13 | Same 13 V ±5 %, SOD-123 package, 400 mW Ptot, 200 Ω rdif max | Higher power rating suits higher-current regulation; larger package increases board area | Select when >300 mW continuous dissipation is needed or SOD-123 is already standardized in design |
| Vishay BZX384-B13 | 13 V ±2 % tolerance, same SOD323 package, identical 300 mW rating and 150 °C Tj | Tighter tolerance improves accuracy in precision references but increases cost | Choose for applications requiring <±2 % regulation error, such as calibrated sensor excitation |
Compared with BZX384-C13,115, the BZT52-C13 offers higher power headroom at the expense of footprint size, while the BZX384-B13 trades ±5 % tolerance for ±2 % accuracy without changing thermal or package constraints - enabling direct substitution only where tolerance relaxation or tightening aligns with system error budget.

FAQ
What is the maximum reverse voltage before breakdown for BZX384-C13,115?
The maximum reverse voltage before reaching the specified Zener breakdown is 10.4 V, defined as VR in the datasheet. At this voltage, reverse current remains ≤30 μA - ensuring the diode stays in non-conductive state until the 12.4–14.1 V breakdown range is reached at 5 mA test current.
Can BZX384-C13,115 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same series, minor VZ mismatches cause current hogging. The BZX384-C13,115 has no built-in matching or thermal coupling for parallel operation; exceeding 300 mW requires a single higher-rated device or active regulation.
What is the forward voltage drop at 10 mA?
The forward voltage is 0.9 V maximum at IF = 10 mA, measured under pulse conditions (tp ≤ 100 μs, duty cycle ≤ 2 %). This value applies during forward conduction, such as in level-shifting configurations, and reflects typical silicon diode behavior at low current.
Is BZX384-C13,115 automotive qualified?
No - per Nexperia's revision history (Rev. 4, Jan 2023), the BZX384 series is explicitly designated as non-automotive qualified. Automotive applications require the −Q qualified variants (e.g., BZX384-C13-Q), which undergo additional AEC-Q200 stress testing and have different qualification documentation.
