Product details
Overview
BZX284-C6V2,135 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 6.2 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 3 µA reverse current at 4 V, used for low-power voltage reference and regulation in space-constrained consumer and industrial PCBs.
For engineers reviewing the BZX284-C6V2,135 datasheet, BZX284-C6V2,135 pinout, BZX284-C6V2,135 application, or BZX284-C6V2,135 equivalent, this page delivers verified electrical parameters, thermal resistance (315 K/W), differential resistance (40–150 Ω), temperature coefficient (+2.3 mV/K), and SOD110 package dimensions - all critical for precision biasing, overvoltage clamping, and analog signal conditioning designs.
Technical Context
The BZX284-C6V2,135 operates as a two-terminal silicon Zener diode with controlled reverse breakdown at 6.2 V, optimized for stable DC voltage reference under low-current conditions (IZtest = 5 mA). Its SOD110 ceramic package enables high thermal stability and low parasitic capacitance (250 pF typical).
It exhibits a positive temperature coefficient of +2.3 mV/K at 5 mA, indicating increasing Zener voltage with junction temperature - a key factor when designing temperature-compensated references or cascaded Zener networks. The device's 40–150 Ω differential resistance defines regulation stiffness under load variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 6.2 V at IZ = 5 mA - precise DC reference point for feedback loops or threshold detection |
| Tolerance | ±5% - supports cost-sensitive applications where tight regulation is not required |
| Total Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C - limits continuous power handling without heatsinking |
| Differential Resistance (rdif) | 40 Ω (typ) to 150 Ω (max) at IZ = 5 mA - determines output impedance and regulation error under current change |
| Reverse Current (IR) | 3 µA at VR = 4 V - defines leakage-induced error in high-impedance bias networks |
| Temperature Coefficient (SZ) | +2.3 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Junction-to-Ambient Thermal Resistance (Rth j-a) | 315 K/W - indicates self-heating rise of ~126 °C/W at full 400 mW dissipation on standard PCB |
Pinout & Package
SOD110 is a very small ceramic rectangular surface-mount package (2.10 × 1.40 × 1.60 mm) with cathode identification marked on top surface. The device has two terminals: anode and cathode, with polarity critical for correct Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse-biased relative to cathode during regulation |
| Cathode (2) | Zener breakdown terminal / voltage reference output | Connected to regulated node; supplies stable 6.2 V relative to anode when reverse-biased above breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD110 ceramic package | Enables placement in ultra-dense layouts with minimal board area (2.1 × 1.4 mm footprint) and high reliability under thermal cycling |
| ±5% voltage tolerance (C-series) | Reduces BOM cost vs. ±2% B-series while maintaining sufficient accuracy for non-critical biasing and protection functions |
| 400 mW power rating | Supports regulation in low-current analog stages (e.g., op-amp references, sensor excitation) without external heat sinking |
| 250 pF typical junction capacitance | Minimizes high-frequency loading in RF detector or fast-switching clamp circuits |
| +2.3 mV/K temperature coefficient | Allows predictable compensation in multi-Zener references or enables intentional temperature sensing in simple circuits |
Applications
| Power Supply Reference | Overvoltage Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | 6.2 V ±5%, SOT-323 package, 200 mW Ptot, 100 Ω rdif (max), 5 µA IR at 4 V | Lower power rating and higher rdif reduce regulation accuracy in >1 mA loads | Select when footprint compatibility with SOT-323 is required and dissipation stays below 200 mW |
| BZX84-C6V2 | 6.2 V ±5%, SOT-23 package, 300 mW Ptot, 60 Ω rdif (max), 3 µA IR at 4 V, Rth j-a = 350 K/W | Higher thermal resistance increases self-heating risk at same power; plastic package less stable than ceramic | Prefer for cost-sensitive volume production where SOT-23 reflow compatibility outweighs ceramic reliability needs |
Compared with MMBZ5234BS-7-F and BZX84-C6V2, the BZX284-C6V2,135 offers superior thermal stability (ceramic SOD110), higher power headroom (400 mW), and tighter rdif control - making it optimal for precision analog biasing where long-term drift and thermal robustness are critical.

FAQ
What is the nominal Zener voltage and test condition for BZX284-C6V2,135?
The BZX284-C6V2,135 has a nominal Zener voltage of 6.2 V measured at a test current (IZtest) of 5 mA, with a tolerance of ±5%. This value is specified in Table 1 of the NXP datasheet and applies under junction temperature conditions of 25 °C. The actual working voltage may vary slightly with current and temperature, as defined by its +2.3 mV/K temperature coefficient and 40–150 Ω differential resistance.
What package type does BZX284-C6V2,135 use and what are its key mechanical dimensions?
The BZX284-C6V2,135 uses the SOD110 very small ceramic SMD package, measuring 2.10 mm × 1.40 mm × 1.60 mm (length × width × height). It features a cathode identifier mark on the top surface and is designed for reflow soldering on standard PCBs. The ceramic construction provides superior thermal stability and moisture resistance compared to plastic packages like SOT-23.
How much reverse leakage current does BZX284-C6V2,135 exhibit at 4 V?
The BZX284-C6V2,135 exhibits a maximum reverse current (IR) of 3 µA when biased at VR = 4 V, as specified in the Electrical Characteristics table of the NXP datasheet. This low leakage ensures minimal loading in high-impedance reference networks and supports accurate biasing in low-power analog circuits where current draw must be tightly controlled.
What is the thermal resistance from junction to ambient for BZX284-C6V2,135?
The thermal resistance from junction to ambient (Rth j-a) for BZX284-C6V2,135 is 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB, per the Thermal Characteristics section of the NXP datasheet. This means the junction temperature rises approximately 126 °C above ambient at full 400 mW dissipation - a critical parameter for derating and reliability analysis in enclosed or high-temperature environments.
Can BZX284-C6V2,135 be used as a replacement for BZX284-B6V2 in existing designs?
The BZX284-C6V2,135 shares identical package, pinout, and nominal voltage with BZX284-B6V2 but differs in tolerance (±5% vs. ±2%) and differential resistance (40–150 Ω vs. 40–150 Ω for B-series, though B6V2 has tighter typical rdif). It is electrically compatible for applications where ±5% voltage accuracy is acceptable, but not recommended for precision references requiring ±2% stability. Always verify system-level regulation error before substitution.
