Product details
Overview
BZX884S-C36-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 36 V Zener voltage with ±5 % tolerance, 80 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C36-QYL datasheet, BZX884S-C36-QYL pinout, BZX884S-C36-QYL application, or BZX884S-C36-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low 0.9 V forward voltage at 10 mA - critical for low-power biasing and clamping in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under varying load and temperature conditions. Its temperature coefficient of +35 mV/K at IZ = 2 mA and 36 V nominal working voltage enables predictable drift compensation in feedback networks.
The device uses silicon planar epitaxial construction with cathode-anode polarity defined by a top-side marking bar. It is rated for 200 mA maximum forward current and supports reverse leakage currents as low as 0.05 μA at VR = 34.2 V, ensuring minimal standby power loss in voltage-sensing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines precise clamping threshold for 36 V nominal rail protection |
| Differential Resistance (rdif) | 80 Ω typical at IZ = 2 mA - determines regulation stiffness and output impedance in shunt references |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous power handling without heatsinking |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables low-loss forward conduction during transient recovery or biasing |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments and industrial enclosures |
| Reverse Leakage (IR) | 0.05 μA max at VR = 34.2 V - ensures negligible current draw below breakdown, critical for battery-powered sensing |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-small footprint with side-wettable flanks for AOI-compatible reflow |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and a marking bar indicating the cathode. Dimensions: 1.0 mm × 0.6 mm × 0.47 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B36-Q | Nominal 36 V with ±2 % tolerance (vs. ±5 %); 60 Ω rdif at IZ = 5 mA | Higher accuracy required in closed-loop feedback; tighter thermal drift | Select when regulation stability <±1 % is mandatory and cost premium is acceptable |
| MMSZ5245B-TP | 36 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, no side-wettable flanks | Legacy board redesigns requiring larger footprint but higher power margin | Choose for compatibility with existing SOD-123 footprints or when >365 mW dissipation is needed |
Compared with BZX884S-C36-QYL, BZX884S-B36-Q offers tighter voltage control at higher test current but lacks automotive qualification, while MMSZ5245B-TP provides greater power headroom in a non-AEC-Q101, non-AOI-friendly package - making the C36-QYL optimal for new automotive and space-constrained industrial designs requiring verified reliability and manufacturability.

FAQ
What is the maximum reverse voltage before breakdown for BZX884S-C36-QYL?
The BZX884S-C36-QYL exhibits sharp Zener breakdown between 34.0 V and 38.0 V at IZ = 2 mA, with guaranteed regulation starting at 34.2 V (95 % of nominal). Below this, reverse leakage remains ≤0.05 μA at 34.2 V, confirming stable non-conducting behavior until the specified knee voltage is reached.
Can BZX884S-C36-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and parameter spread; paralleling causes current hogging and thermal runaway. For >365 mW needs, use a single higher-power device like the PZUX36 or implement active regulation with a transistor-based shunt amplifier.
How does the side-wettable flank design impact solder joint inspection?
The side-wettable flanks on the DFN1006BD-2 package allow standard 2D AOI systems to detect solder fillet height, wetting angle, and bridging - eliminating need for costly X-ray inspection and reducing defect escape rate in high-volume automotive PCB assembly.
Is the 365 mW power rating valid for all PCB configurations?
No - the 365 mW rating applies only to the standardized test condition: FR4 board, single-sided 70 μm copper, tin-plated, and Nexperia's recommended footprint. On 4-layer boards with internal ground planes, derating is unnecessary; on 1-layer phenolic boards, power must be reduced by ≥40 % to avoid exceeding 150 °C junction temperature.
