Product details
Overview
BZX884S-B3V6-QYL from Nexperia is a ±2 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision voltage regulation at 3.6 V nominal breakdown voltage with 5 μA reverse current and 375 Ω differential resistance at IZ = 5 mA. It operates across −55 °C to +150 °C ambient and supports automotive-grade power rail stabilization.
For engineers reviewing the BZX884S-B3V6-QYL datasheet, BZX884S-B3V6-QYL pinout, BZX884S-B3V6-QYL application, or BZX884S-B3V6-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for solder joint inspection, 365 mW power dissipation on FR4, and tight 3.53–3.67 V Zener voltage range at 25 °C.
Technical Context
This Zener diode functions as a two-terminal shunt voltage reference, maintaining stable output by conducting reverse current above its specified breakdown voltage. Its low 375 Ω dynamic impedance at 5 mA ensures minimal voltage deviation under load variation, while the negative temperature coefficient of −3.5 mV/K enables predictable thermal drift compensation in bias networks.
The device uses silicon planar epitaxial construction with cathode-marked top-side bar alignment, optimized for reflow-only assembly on standard FR4 PCBs. Its 0.65 mm pitch, 1.0 × 0.6 × 0.47 mm body and side-wettable flanks meet IPC-7351B Class L requirements for automated optical inspection (AOI) of solder fillets.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B3V6-Q | Same electrical specs and package; differs only in marking code (2E vs QYL) and tape/reel packaging variant. | No functional difference; identical performance in all circuit roles. | Select when standard reel packaging suffices and no custom labeling is required. |
| MMSZ4685T1G | ±5 % tolerance, 3.7 V nominal VZ, SOD-123 package (larger, non-SWF), 500 mW Ptot. | Higher voltage drift and no AOI support; suitable only for non-automotive cost-sensitive designs. | Choose only if board space allows larger footprint and AEC-Q101 compliance is not mandated. |
Compared with BZX884S-B3V6-QYL, the BZX884S-B3V6-Q offers identical regulation performance with standard logistics packaging, while MMSZ4685T1G trades precision and manufacturability for higher power and lower cost-making the QYL variant optimal for space-constrained, automotive-grade shunt regulation where traceability and process control are critical.

FAQ
What is the maximum continuous reverse current this Zener diode can handle?
The BZX884S-B3V6-QYL supports up to 200 mA forward current per absolute maximum ratings, but as a Zener regulator, its practical reverse conduction is limited by power dissipation. At 3.6 V, sustained operation above ~100 mA requires thermal derating beyond 25 °C ambient due to its 340 K/W junction-to-ambient thermal resistance on FR4.
Does the side-wettable flank design require special stencil or reflow profile?
No special stencil is needed-the standard SOD882BD footprint (1.3 mm pad length, 0.7 mm width) works with Type 3 solder paste. Reflow must follow JEDEC J-STD-020 profiles for MSAL3; peak temperature ≤260 °C is mandatory to avoid delamination, and ramp rates must stay within 3 °C/s to prevent voiding in the ultra-thin 0.47 mm body.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy over temperature?
At 3.6 V nominal, the −3.5 mV/K coefficient causes ~−0.35 V drift from −40 °C to +125 °C ambient. In practice, this translates to ~−9.7 mV/°C change in VZ, meaning a 100 °C rise shifts regulation by −350 mV-requiring system-level compensation or use within narrow ambient bands for sub-1 % accuracy.
Can this Zener diode replace a 3.3 V TVS for ESD protection?
No-it is not rated for ESD pulse handling. While it clamps at ~3.6 V, its 365 mW steady-state rating and lack of IEC 61000-4-2 certification mean it cannot safely absorb 8 kV contact discharge energy. Use dedicated TVS diodes like PESD3V3L1BA for ESD protection; this Zener serves only steady-state regulation and low-energy transient suppression.
