Product details
Overview
BZX284-C13,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in SOD110 ceramic SMD package, rated for 13 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 100 nA reverse leakage at 8 V, used for low-power voltage reference and regulation in space-constrained PCBs.
For engineers reviewing the BZX284-C13,115 datasheet, BZX284-C13,115 pinout, BZX284-C13,115 application, or BZX284-C13,115 equivalent, this page delivers verified electrical parameters, thermal resistance (315 K/W), differential resistance (25–170 Ω), temperature coefficient (+9.4 mV/K), and SOD110 package dimensions for accurate schematic capture and layout integration.
Technical Context
The BZX284-C13,115 operates as a two-terminal passive voltage reference, relying on controlled Zener breakdown in silicon PN junction under reverse bias. Its regulation performance is defined at IZtest = 5 mA with VZ = 12.7–13.3 V, and it exhibits a positive temperature coefficient of +9.4 mV/K - critical for thermal stability in ambient-varying environments.
Designed for surface-mount assembly on standard FR-4 PCBs (11 × 25 × 1.6 mm), the device delivers stable regulation within its 250 mA continuous forward current limit and 12 A non-repetitive peak reverse surge capability (tp = 100 μs), while maintaining low junction-to-ambient thermal resistance of 315 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference rails. |
| Tolerance | ±5% - allows use in cost-sensitive applications where tighter tolerance is not required. |
| Power Dissipation | 400 mW at Tamb = 25 °C - sets maximum steady-state power handling before thermal derating applies. |
| Differential Resistance | 25–170 Ω - determines output impedance and load regulation sensitivity across operating current range. |
| Reverse Leakage Current | 100 nA at VR = 8 V - ensures minimal quiescent current draw in standby or low-power modes. |
| Temperature Coefficient | +9.4 mV/K - indicates voltage increases with temperature, requiring compensation in precision references. |
| Junction Temperature | 150 °C max - defines upper thermal limit for reliable long-term operation. |
Pinout & Package
SOD110 is a very small ceramic rectangular surface-mounted package (2.10 × 1.40 × 1.60 mm) with cathode marked on top surface; terminals are anode (pin 1) and cathode (pin 2), mounted on standard PCB pads per JEDEC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry / reverse bias return path | Connected to lower-potential node; forms current loop with cathode during regulation. |
| Cathode (Pin 2) | Zener voltage reference terminal | Connected to regulated output node; voltage measured relative to anode defines VZ. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD packaging | SOD110 footprint (2.1 × 1.4 mm) enables high-density routing and automated placement in compact consumer and industrial PCBs. |
| Controlled Zener breakdown | Stable 13 V regulation with predictable rdif and SZ enables repeatable reference design without external trimming. |
| High surge robustness | 12 A non-repetitive peak reverse current (tp = 100 μs) supports transient overvoltage protection in input-stage clamping. |
| Wide operating temperature | −65 °C to +150 °C storage range ensures reliability in automotive under-hood and industrial control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulator diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-C13 | Same SOD-123 package, ±5% tolerance, VZ = 13 V @ 5 mA, but higher rdif (max 180 Ω) and lower Ptot (500 mW). | Higher power rating suits higher-current regulation; larger SOD-123 footprint requires layout change. | Select when board space allows SOD-123 and >400 mW dissipation is needed. |
| Vishay BZX84-C13 | SOD-323 package (1.7 × 1.25 mm), same VZ and tolerance, but lower Ptot (300 mW) and higher thermal resistance (450 K/W). | Smaller footprint saves area but limits thermal performance in sustained-load scenarios. | Select only for ultra-compact designs with low-duty-cycle regulation requirements. |

FAQ
What is the nominal Zener voltage and test condition for BZX284-C13,115?
The BZX284-C13,115 has a nominal Zener voltage of 13 V, specified at a test current (IZtest) of 5 mA and junction temperature of 25 °C. The actual working voltage range is 12.7 V to 13.3 V, reflecting its ±5% tolerance. This value is critical for setting reference points in feedback networks and must be verified under actual operating current and thermal conditions.
What package type and dimensions does BZX284-C13,115 use?
BZX284-C13,115 uses the SOD110 ceramic surface-mount package measuring 2.10 mm × 1.40 mm × 1.60 mm, with cathode identified by a marking on the top surface. Its compact footprint supports high-density PCB layouts, and the ceramic construction provides superior thermal stability compared to plastic-packaged Zeners.
What is the maximum reverse leakage current for BZX284-C13,115 and at what voltage is it measured?
The maximum reverse leakage current for BZX284-C13,115 is 100 nA, measured at VR = 8 V and Tamb = 25 °C. This low leakage ensures minimal parasitic current draw in battery-powered or high-impedance circuits, preserving system efficiency and reference accuracy in standby operation.
How does the temperature coefficient affect BZX284-C13,115's regulation performance?
The BZX284-C13,115 has a temperature coefficient of +9.4 mV/K, meaning its Zener voltage increases by approximately 9.4 mV per degree Celsius rise in junction temperature. This positive TC must be accounted for in precision reference designs, especially in environments with wide ambient swings or self-heating under load.
What is the thermal resistance and how does it impact BZX284-C13,115's power handling?
BZX284-C13,115 has a junction-to-ambient thermal resistance (Rth j-a) of 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB. At its rated 400 mW power dissipation, this results in a ~126 K temperature rise above ambient - requiring careful thermal management in enclosed or high-temperature environments to avoid exceeding the 150 °C max junction limit.
