Product details
Overview
BZX284-C36,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 36 V nominal working voltage at 2 mA test current, 400 mW total power dissipation, and 33.0 V minimum/38.0 V maximum Zener voltage range. It serves as a precision low-power voltage reference in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the BZX284-C36,115 datasheet, BZX284-C36,115 pinout, BZX284-C36,115 application, or BZX284-C36,115 equivalent, key selection criteria include its ±5% tolerance, 300 Ω max differential resistance at 2 mA, −40 to +150 °C operating junction temperature, and suitability for space-constrained SMD regulation in consumer and industrial power management.
Technical Context
This device operates in reverse breakdown mode with a specified Zener voltage of 35.3–36.7 V at IZtest = 2 mA, exhibiting a typical temperature coefficient of +15 mV/K. Its differential resistance remains ≤300 Ω under standard test conditions, supporting stable regulation across ambient temperature variations.
The SOD110 package provides thermal resistance of 315 K/W (junction-to-ambient, mounted on 11 × 25 × 1.6 mm PCB), enabling reliable operation up to 150 °C junction temperature. Reverse leakage is limited to 50 nA at VR = 0.7 × VZnom, ensuring low quiescent current in standby regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.3–36.7 V at IZ = 2 mA - defines precise regulation threshold for feedback loops |
| Tolerance | ±5% - specifies allowable deviation from nominal 36 V for cost-sensitive designs |
| Differential Resistance (rdiff) | ≤300 Ω at IZ = 2 mA - determines load regulation error and output impedance |
| Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C - sets maximum continuous power handling without derating |
| Reverse Leakage (IR) | 50 nA at VR = 25.2 V - ensures minimal current draw in high-impedance bias networks |
| Junction Temperature (Tj) | −40 to +150 °C - enables deployment in extended-temperature industrial environments |
| Package | SOD110 - ultra-small ceramic SMD footprint (2.1 × 1.4 × 1.6 mm) for dense PCB layouts |
Pinout & Package
SOD110 is a two-terminal surface-mount ceramic package with cathode marked by a band on one end. Terminals are non-polarized in function but polarity-critical in circuit connection.

| Anode (unmarked end) | Forward conduction terminal / low-side reference node | Connected to ground or lower potential in shunt regulator configuration |
| Cathode (banded end) | Zener breakdown terminal / regulated output node | Connected to input voltage source and feedback point; carries reverse current during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD110 packaging | Enables placement in height-restricted modules (max height 1.6 mm) without compromising thermal path |
| ±5% voltage tolerance | Reduces BOM cost versus ±2% variants while maintaining adequate accuracy for non-critical rails |
| 400 mW power rating | Supports regulation of up to ~11 mA at 36 V without external heatsinking in standard PCB layout |
| 150 °C max junction temperature | Permits operation in sealed enclosures or near heat-generating components without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-C36 | Same SOD123 package, ±5% tolerance, 36 V nominal, 500 mW Ptot, 400 Ω rdiff | Higher power rating supports higher clamp currents; larger footprint may require PCB redesign | Select when higher surge robustness is required and board area permits SOD123 |
| Vishay PLZ36 | SOD123 package, ±5%, 36 V, 500 mW, 350 Ω rdiff, AEC-Q200 qualified | Automotive-qualified variant with enhanced reliability testing; not suitable for cost-sensitive consumer use | Select for automotive-grade designs requiring qualification evidence and extended temperature validation |
Compared with BZX284-C36,115, BZT52-C36 offers higher power headroom in a slightly larger package, while PLZ36 adds automotive qualification at premium cost-neither is pin-compatible due to differing SOD110 vs. SOD123 footprints, requiring layout revision.

FAQ
What is the Zener voltage tolerance of BZX284-C36,115?
The BZX284-C36,115 has a ±5% tolerance on its nominal 36 V Zener voltage, resulting in a guaranteed range of 34.0 V to 38.0 V at IZ = 2 mA. This tolerance is confirmed in Table 2 of the NXP datasheet and applies specifically to the "C" series variants, distinguishing it from the tighter ±2% "B" series.
What is the maximum power dissipation for BZX284-C36,115?
The BZX284-C36,115 has a maximum total power dissipation of 400 mW at an ambient temperature of 25 °C, as specified in the Limiting Values table. Derating is required above 25 °C per the thermal resistance of 315 K/W, and actual usable power depends on PCB copper area and airflow.
Does BZX284-C36,115 have a specified temperature coefficient?
Yes, the BZX284-C36,115 has a typical temperature coefficient of +15 mV/K at IZ = 2 mA, as listed in Table 2 of the NXP datasheet. This positive coefficient indicates that its Zener voltage increases linearly with junction temperature, enabling predictable drift modeling in thermal-aware designs.
What is the reverse leakage current specification for BZX284-C36,115?
The reverse leakage current for BZX284-C36,115 is specified as 50 nA maximum at VR = 0.7 × VZnom = 25.2 V, per the Electrical Characteristics table. This value reflects low standby current critical for battery-operated systems where quiescent power must be minimized.
Which package type does BZX284-C36,115 use?
BZX284-C36,115 uses the SOD110 package - a very small ceramic rectangular surface-mount device measuring 2.10 × 1.40 × 1.60 mm, with cathode identified by a band. The package outline and dimensions are fully documented in the Package Outline section of the NXP datasheet.
