Product details
Overview
BZX884-C3V3,315 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, providing precise 3.3 V voltage regulation at 5 mA test current with 3.23 V to 3.37 V nominal range, 350 Ω typical differential resistance, and −1.8 mV/K temperature coefficient - used for low-power voltage reference and ESD protection in space-constrained consumer and automotive electronics.
For engineers reviewing the BZX884-C3V3,315 datasheet, BZX884-C3V3,315 pinout, BZX884-C3V3,315 application, or BZX884-C3V3,315 equivalent, key selection criteria include Zener voltage tolerance, thermal coefficient, reverse leakage at 1 V (5 µA max), power dissipation limit (250 mW), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled knee characteristics, enabling stable regulation under low-current conditions (IZ = 5 mA). Its −1.8 mV/K temperature coefficient minimizes drift across −55 °C to +150 °C ambient range, and its 410 pF capacitance at 1 MHz supports high-frequency decoupling roles.
The device uses planar epitaxial construction for consistent breakdown behavior and low noise performance. It is rated for non-repetitive peak reverse current of 6 A at 100 µs pulse width, supporting transient suppression in compact power rails and I/O line protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.23 V to 3.37 V at IZ = 5 mA - defines tight regulation window for 3.3 V rail referencing |
| Tolerance | ±5% - enables cost-optimized design where tighter tolerance is not required |
| Differential Resistance (rdiff) | 350 Ω typ. at IZ = 1 mA - determines load regulation sensitivity and output impedance |
| Reverse Leakage (IR) | 5 µA max at VR = 1 V - ensures minimal quiescent current in standby mode |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Temperature Coefficient (SZ) | −1.8 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal stability analysis |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - ultra-small footprint for high-density PCB layouts |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B3V3,315 | ±2% tolerance (3.27–3.33 V), lower rdiff (325 Ω typ.), same package and AEC-Q101 rating | Required where tighter regulation is needed for precision analog sensing or feedback loops | Select when absolute voltage accuracy outweighs cost sensitivity |
| MMSZ5226B-7-F | ±5% tolerance, SOD-123 package (2.7 × 1.6 × 1.1 mm), higher Ptot (500 mW), no AEC-Q101 qualification | Suitable for non-automotive industrial power supplies needing higher power margin | Choose only for non-automotive designs where larger footprint and absence of automotive qualification are acceptable |
Compared with BZX884-C3V3,315, the BZX884-B3V3,315 offers tighter voltage control at identical size and qualification, while MMSZ5226B-7-F trades miniaturization and automotive compliance for higher power handling in legacy footprints.

FAQ
What is the maximum continuous reverse current the BZX884-C3V3,315 can handle?
The device has no specified maximum continuous reverse current; its operation relies on limiting power dissipation to 250 mW. At 3.3 V Zener voltage, this corresponds to ~75 mA average reverse current under ideal thermal conditions. Derating is required above 25 °C ambient per the 500 K/W junction-to-ambient thermal resistance.
Is the BZX884-C3V3,315 suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode configured for reverse-bias operation only. For bidirectional ESD protection, a dedicated TVS diode such as PESD5V0S1BA should be used. The BZX884-C3V3,315 functions solely as a cathode-grounded clamp in forward conduction or reverse breakdown.
How does the −1.8 mV/K temperature coefficient affect circuit performance at 125 °C?
From 25 °C to 125 °C (ΔT = 100 K), the Zener voltage shifts by −180 mV, resulting in a regulated value of approximately 3.15 V. This 5.4% deviation must be accounted for in reference-sensitive circuits; it is within specification for AEC-Q101 automotive grade but may require trimming in precision analog designs.
Can the BZX884-C3V3,315 replace a 3.3 V linear regulator in low-current applications?
No - it lacks current regulation capability and cannot source load current like an LDO. It provides voltage reference or clamping only. When used as a shunt regulator, it requires a series resistor to limit current, and output voltage varies with load due to finite rdiff; it is not a drop-in replacement for active regulators.
