Product details
Overview
BZX884S-C8V2-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in compact automotive and industrial circuits. It delivers a nominal 8.2 V breakdown voltage with ±5 % tolerance, 365 mW power dissipation, and operates across −55 °C to +150 °C ambient temperature - validated per AEC-Q101 for under-hood automotive use.
For engineers reviewing the BZX884S-C8V2-QYL datasheet, BZX884S-C8V2-QYL pinout, BZX884S-C8V2-QYL application, or BZX884S-C8V2-QYL equivalent, key selection criteria include its DFN1006BD-2 side-wettable flank package, low differential resistance (40 Ω at IZ = 5 mA), temperature coefficient of +3.2 mV/K, and reverse current ≤0.7 μA at VR = 6.2 V.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage under varying load and temperature conditions. Its 8.2 V nominal Zener voltage is specified at 5 mA test current, with typical differential resistance of 40 Ω and positive temperature coefficient (+3.2 mV/K) ensuring predictable drift behavior above 6 V.
The device uses silicon planar epitaxial construction and is qualified to AEC-Q101 for automotive reliability. Thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, enabling operation up to 150 °C junction temperature with appropriate layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.7 V to 8.7 V at IZ = 5 mA - defines regulated output range for reference or clamp applications |
| Tolerance | ±5 % - supports cost-sensitive designs where tighter regulation is not required |
| Differential Resistance (rdif) | 40 Ω (typ) at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Ptot) | 365 mW - sets maximum continuous DC or pulsed power handling on standard FR4 PCB |
| Reverse Current (IR) | ≤0.7 μA at VR = 6.2 V - ensures low leakage in high-impedance bias networks |
| Temperature Coefficient (SZ) | +3.2 mV/K - enables predictable voltage drift compensation in thermal-aware designs |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction threshold when used in forward-bias protection paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B8V2-Q | Same package and 8.2 V nominal voltage but ±2 % tolerance (vs. ±5 %) | Higher precision required in metrology-grade references or feedback loops | Select when tighter voltage stability outweighs cost sensitivity |
| MMSZ5236B-7-F | SOD-123 package (2.7 × 1.6 mm), ±5 % tolerance, 350 mW Ptot, 30 Ω rdif | Less space-constrained boards where larger footprint is acceptable | Choose for legacy compatibility or where lower dynamic impedance is prioritized over size |
Compared with BZX884S-C8V2-QYL, the BZX884S-B8V2-Q offers improved voltage accuracy at higher cost, while MMSZ5236B-7-F trades miniaturization for slightly better regulation performance and broader distributor availability - making it suitable for prototyping or mixed-technology assemblies.

FAQ
What is the maximum continuous reverse current this Zener can handle before degradation?
The absolute maximum limiting value for forward current is 200 mA, but for Zener operation, the critical limit is total power dissipation: 365 mW at Tamb = 25 °C on standard FR4. At 8.2 V, this corresponds to ~44.5 mA continuous Zener current. Exceeding this without derating reduces reliability and risks thermal runaway.
Does the side-wettable flank design require special stencil or reflow profile?
No special stencil is required - the recommended reflow footprint matches standard DFN1006BD-2 land patterns (1.3 mm × 0.8 mm pads, 0.6 mm spacing). Reflow must follow JEDEC J-STD-020 profile for MSAL3 moisture sensitivity level; peak temperature ≤260 °C is mandatory to avoid delamination.
How does the +3.2 mV/K temperature coefficient affect regulation accuracy over temperature?
At 8.2 V nominal, +3.2 mV/K yields ~±0.39 V drift over −40 °C to +125 °C (165 K range). This is predictable and linear, allowing compensation in firmware or analog circuitry. For uncalibrated systems, it contributes ±4.8 % full-scale error - acceptable for non-precision biasing but insufficient for metrology-grade references.
Can this Zener be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient mismatch and unequal current sharing when paralleled, leading to thermal runaway in one device. For higher power, use a single higher-rated Zener (e.g., BZX85C8V2) or implement active regulation with a pass transistor and reference.
