Product details
Overview
BZX884S-C33-QYL from Nexperia is a ±5 % tolerance Zener diode in SOD882BD (DFN1006BD-2) package, rated for 33 V nominal breakdown voltage at IZ = 2 mA, with 75 Ω typical differential resistance, 0.05 μA max reverse current at VR = 27 V, and qualified to AEC-Q101 for automotive voltage regulation.
For engineers reviewing the BZX884S-C33-QYL datasheet, BZX884S-C33-QYL pinout, BZX884S-C33-QYL application, or BZX884S-C33-QYL equivalent, this device serves as a precision shunt regulator in low-power supply rails, ESD-protected reference nodes, and automotive sensor biasing circuits where side-wettable flanks enable reliable reflow inspection.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 33 V nominal Zener voltage is specified at 2 mA test current, with a temperature coefficient of +18.9 mV/K and thermal resistance of 340 K/W when mounted on standard FR4 PCB.
The DFN1006BD-2 package features side-wettable flanks for automated optical solder-joint inspection, and its 1.0 mm × 0.6 mm footprint supports high-density automotive PCB layouts. The cathode is marked by a visible bar on the top surface, aligning with Pin 1 per JEDEC MO-343AA outline.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B33-Q | ±2 % tolerance (vs. ±5 %), 60 Ω rdif, 0.05 μA IR at 27 V | Higher precision required for reference-grade biasing; tighter tempco (18.4 mV/K) | Select when <1 % voltage drift over temperature is mandatory; accept higher cost and tighter inventory control |
| MMSZ5261B-TP | 33 V, ±5 %, SOD-123 package, 350 mW Ptot, 90 Ω rdif, no AEC-Q101 rating | Limited to industrial/commercial use; larger 2.7 × 1.6 mm footprint; no side-wettable flanks | Choose only for non-automotive prototypes where AOI is not required and board space is unconstrained |
Compared with BZX884S-B33-Q, the C33-Q offers relaxed tolerance for cost-sensitive automotive functions; versus MMSZ5261B-TP, it delivers AEC-Q101 compliance and 40 % smaller footprint-critical for space-constrained ADAS modules.

FAQ
What is the maximum continuous reverse current the BZX884S-C33-QYL can sustain?
The device sustains up to 200 mA forward current per Absolute Maximum Ratings, but as a Zener diode, its continuous reverse current is limited by power dissipation: at 33 V, maximum safe DC current is ~11 mA (365 mW ÷ 33 V). Pulse operation allows higher peak currents if duty cycle and thermal mass permit.
Does the side-wettable flank design require special stencil or reflow profile?
No special stencil is needed-the standard SOD882BD footprint (1.3 mm × 0.7 mm solder pads) works with industry-standard Type 4 paste. Reflow must follow Nexperia's recommended profile: peak 260 °C for ≤ 30 s, with ramp rates ≤ 3 °C/s, to ensure wetting without voiding or delamination.
How does the ±5 % tolerance affect regulation accuracy in a 33 V rail?
At 25 °C, the actual breakdown voltage falls between 31.35 V and 34.65 V. Combined with +18.9 mV/K temperature coefficient, worst-case variation over −40 °C to +150 °C is ±2.1 V-still sufficient for non-critical clamping or biasing where absolute accuracy is secondary to robustness and cost.
Can BZX884S-C33-QYL replace older BZX884-B33 variants in existing designs?
Yes, with identical pinout, package, and electrical specs except tolerance (±5 % vs. ±2 %) and slightly higher rdif. No layout change is needed. However, verify that the looser tolerance meets system-level voltage margin requirements-especially in feedback loops or comparator thresholds.
