Product details
Overview
BZX884S-C3V3-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 3.3 V Zener voltage with ±5 % tolerance, 365 mW power dissipation, and operates across −55 °C to +150 °C ambient temperature - qualified per AEC-Q101 for under-hood automotive use.
For engineers reviewing the BZX884S-C3V3-QYL datasheet, BZX884S-C3V3-QYL pinout, BZX884S-C3V3-QYL application, or BZX884S-C3V3-QYL equivalent, key selection factors include its DFN1006BD-2 side-wettable flank package, 3.3 V regulation at 5 mA, low 5 μA reverse current at VR = 3.0 V, and differential resistance of 350 Ω (IZ = 5 mA), critical for stable biasing in sensor interfaces and power rail clamping.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 3.3 V reference across load variations and temperature shifts. Its design integrates a low-capacitance structure (260 pF at 1 MHz, VR = 0 V) and negative temperature coefficient (−3.5 mV/K at IZ = 5 mA), enabling predictable drift compensation in analog front-ends.
Manufactured in an ultra-small leadless SOD882BD (DFN1006BD-2) package with side-wettable flanks, it supports automated optical inspection (AOI) and high-yield reflow soldering on FR4 PCBs - meeting automotive reliability requirements without requiring through-hole mounting or discrete heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.3 V nominal at IZ = 5 mA; provides precise 3.3 V reference for MCU reset circuits and ADC reference buffers |
| Tolerance | ±5 %; enables cost-effective regulation where tight voltage accuracy is not required, e.g., non-critical supply monitoring |
| Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on standard FR4; supports continuous operation in space-constrained automotive modules |
| Differential Resistance (rdif) | 350 Ω at IZ = 5 mA; ensures minimal output voltage shift under dynamic load changes in feedback networks |
| Reverse Current (IR) | 5 μA max at VR = 3.0 V; guarantees low leakage in battery-backed circuits and low-power wake-up detection paths |
| Junction Temperature (Tj) | 150 °C max; allows reliable operation in engine control units and powertrain ECUs with elevated thermal environments |
| Package | DFN1006BD-2 (SOD882BD); 1.0 mm × 0.6 mm × 0.47 mm body with side-wettable flanks for AOI-compatible reflow assembly |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed for correct reverse-bias operation in shunt regulation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield in high-volume auto production |
| Low thermal resistance | Rth(j-a) = 340 K/W on FR4; permits direct integration into thermally dense modules without external heatsinking |
| Wide operating temperature | −55 °C to +150 °C ambient range; supports deployment in under-hood, transmission, and brake control systems |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series); C3V3-QYL offers cost-optimized regulation for non-critical voltage references |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B3V3-Q | Nominal VZ = 3.3 V with ±2 % tolerance (vs. ±5 %); rdif = 325 Ω at 5 mA (vs. 350 Ω) | Higher accuracy required in precision ADC references or voltage-controlled oscillator tuning | Select when tighter regulation stability (<±66 mV) is needed despite 15 % higher unit cost |
| MMSZ4676T1G | VZ = 3.3 V, ±5 %, but in SOD-123 package (2.7 mm × 1.6 mm); Ptot = 500 mW; Rth(j-a) = 270 K/W | Preferred where board space is less constrained and higher power handling is required for surge absorption | Choose for industrial power supplies needing >365 mW dissipation margin or legacy footprint compatibility |
Compared with BZX884S-C3V3-QYL, the BZX884S-B3V3-Q improves voltage accuracy at the expense of cost and thermal performance, while MMSZ4676T1G trades miniaturization for higher power capability and different thermal behavior - making each suitable for distinct mechanical, thermal, and precision constraints.

FAQ
What is the maximum reverse current at 3.0 V for BZX884S-C3V3-QYL?
The maximum reverse current (IR) is 5 μA at VR = 3.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage ensures minimal power loss in always-on monitoring circuits and preserves battery life in sleep-mode automotive subsystems.
Can BZX884S-C3V3-QYL be used in place of a 3.3 V TVS diode for ESD protection?
No - it is a Zener regulator diode optimized for steady-state voltage reference, not transient suppression. Its 365 mW power rating and 350 Ω dynamic resistance make it unsuitable for absorbing IEC 61000-4-2 ESD pulses; dedicated TVS devices like PESD3V3L1BA have faster response and higher peak pulse power ratings.
Is the DFN1006BD-2 package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with validated profiles matching IPC/JEDEC J-STD-020. The side-wettable flanks enable reliable joint formation and AOI verification on standard SMT lines without process modification.
How does temperature affect the 3.3 V Zener voltage of this device?
It exhibits a negative temperature coefficient of −3.5 mV/K at IZ = 5 mA, meaning VZ decreases by ~3.5 mV per 1 K rise in junction temperature. This drift is characterized and repeatable, allowing system-level compensation in closed-loop designs where absolute accuracy is secondary to monotonic behavior.
