Product details
Overview
BZX284-C2V4,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 2.4 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 150 °C maximum junction temperature - used for low-power voltage reference and overvoltage protection in power supply rails and signal conditioning circuits.
For engineers reviewing the BZX284-C2V4,115 datasheet, BZX284-C2V4,115 pinout, BZX284-C2V4,115 application, or BZX284-C2V4,115 equivalent, key selection considerations include its 2.4 V regulation tolerance, 50 µA reverse leakage at 1 V, 275–400 Ω differential resistance, and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BZX284-C2V4,115 operates as a two-terminal passive voltage reference, relying on controlled Zener breakdown in silicon PN junctions to maintain stable reverse-biased voltage under varying load currents. Its regulation performance is specified at 5 mA test current and 25 °C ambient, with thermal coefficient of −1.6 mV/K and junction-to-ambient thermal resistance of 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB.
Designed for low-power applications, it delivers stable 2.4 V reference with ≤5% tolerance across manufacturing lots, supports continuous forward current up to 250 mA, and withstands non-repetitive reverse surge currents up to 12 A (100 µs pulse) - enabling use in transient suppression and precision biasing where minimal quiescent current and small form factor are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 2.4 V at IZ = 5 mA - defines primary regulation point for low-voltage reference circuits |
| Tolerance | ±5% - ensures output voltage remains within 2.28–2.52 V under production variation |
| Power Dissipation | 400 mW at Tamb = 25 °C - sets maximum steady-state power handling without heatsinking |
| Differential Resistance | 275–400 Ω at IZ = 5 mA - determines regulation stiffness and output impedance under load changes |
| Reverse Leakage | 50 µA at VR = 1 V - establishes minimum operating voltage threshold before regulation onset |
| Thermal Coefficient | −1.6 mV/K - quantifies voltage drift per degree Celsius, critical for temperature-stable references |
| Junction Temperature | 150 °C max - defines upper thermal limit for reliable long-term operation |
Pinout & Package
SOD110 is a very small ceramic surface-mount package with two terminals: anode (pin 1) and cathode (pin 2), marked by a cathode band on the top surface. The package measures 1.90–2.10 mm in length, 1.10–1.40 mm in width, and 1.6 mm maximum height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Forward current entry / reverse voltage reference ground | Connected to lower-potential node; forms reference return path in shunt regulator configuration |
| Cathode (2) | Reverse voltage input / regulated output node | Connected to higher-potential rail; provides stable 2.4 V relative to anode during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD110 ceramic package | Enables placement in ultra-compact PCB designs (<2.1 mm × 1.4 mm footprint) without compromising thermal reliability |
| ±5% voltage tolerance | Provides cost-optimized regulation accuracy suitable for non-critical biasing and clamping functions |
| 400 mW power rating | Supports stable operation at up to 167 mA average Zener current (2.4 V × 167 mA ≈ 400 mW) |
| −1.6 mV/K temperature coefficient | Minimizes voltage drift across industrial temperature range (−65 to +150 °C) |
| 12 A non-repetitive surge capability | Offers transient overvoltage resilience in unprotected input stages without external TVS devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulator diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | 2.4 V ±5%, SOT-23 package, 350 mW rating, 600 Ω dynamic resistance | Higher rdif reduces regulation precision; larger SOT-23 footprint increases board area | Choose when existing layout uses SOT-23 and thermal margin allows 350 mW derating |
| BZX84-C2V4 | 2.4 V ±5%, SOT-23 package, 300 mW rating, 500 Ω dynamic resistance, −1.6 mV/K TC | Lower power and higher rdif limit current-handling and regulation stability vs. BZX284-C2V4,115 | Prefer for legacy SOT-23 designs where 300 mW suffices and ceramic SOD110 is unavailable |
Compared with MMBZ5221BS-7-F and BZX84-C2V4, the BZX284-C2V4,115 offers superior thermal resistance (315 K/W vs. ~400 K/W), lower dynamic resistance (275–400 Ω), and smaller SOD110 footprint - making it optimal for high-density, thermally constrained, or precision-shunt applications.

FAQ
What is the Zener voltage tolerance of the BZX284-C2V4,115?
The BZX284-C2V4,115 has a ±5% tolerance on its nominal 2.4 V Zener voltage, meaning its actual regulation voltage falls between 2.28 V and 2.52 V when tested at 5 mA under standard conditions. This tolerance is confirmed in Table 1 of the NXP datasheet and applies specifically to the "C" series variant of the BZX284-C2V4,115, distinguishing it from the tighter ±2% "B" series variants.
Can the BZX284-C2V4,115 be used in place of a BZX284-B2V4?
No - the BZX284-C2V4,115 and BZX284-B2V4 share identical nominal voltage and package but differ in tolerance (±5% vs. ±2%) and differential resistance (275–400 Ω vs. 275–400 Ω for B-series at same voltage). While electrically interchangeable in non-critical applications, the BZX284-C2V4,115 must not replace the BZX284-B2V4 where ±2% regulation accuracy is required per design specification.
What is the maximum continuous reverse current the BZX284-C2V4,115 can handle?
The BZX284-C2V4,115 does not specify a maximum continuous reverse (Zener) current directly, but its 400 mW power rating at 25 °C ambient implies a maximum average Zener current of approximately 167 mA (400 mW ÷ 2.4 V). Operation above this current requires thermal derating per the 315 K/W junction-to-ambient thermal resistance, and the BZX284-C2V4,115 datasheet confirms safe operation up to 12 A for non-repetitive 100 µs pulses.
Is the BZX284-C2V4,115 RoHS compliant?
Yes - the BZX284-C2V4,115 is manufactured by NXP Semiconductors and conforms to RoHS Directive 2011/65/EU, as verified in NXP's official product change notices and material declarations. The SOD110 ceramic package contains no lead in solderable terminations, and all materials meet restricted substance thresholds for cadmium, hexavalent chromium, mercury, PBB, PBDE, and phthalates.
What is the cathode identification method on the BZX284-C2V4,115 package?
The BZX284-C2V4,115 uses a cathode band marking on the top surface of the SOD110 package, located adjacent to pin 2 (cathode terminal), as shown in Figure 1 of the NXP datasheet. This band aligns with the standard polarity convention for Zener diodes: current flows from cathode to anode during reverse breakdown, and the band must be oriented toward the higher-potential node in shunt regulator configurations.
