Product details
Overview
BZX884S-B36-QYL from Nexperia is a ±2 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision voltage regulation at 36 V nominal breakdown voltage with 80 Ω typical differential resistance at IZ = 2 mA and −0.05 μA reverse current at VR = 27 V. It is AEC-Q101 qualified and used in automotive power rail stabilization and ECU reference circuits.
For engineers reviewing the BZX884S-B36-QYL datasheet, BZX884S-B36-QYL pinout, BZX884S-B36-QYL application, or BZX884S-B36-QYL equivalent, key selection criteria include its 36 V Zener voltage tolerance, side-wettable flank package for automated optical inspection, 365 mW power rating on FR4, and temperature coefficient of +35 mV/K at IZ = 2 mA.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable DC voltage under varying load and line conditions. Its low 80 Ω dynamic impedance ensures minimal output voltage deviation across 1–5 mA operating current range, while the +35 mV/K temperature coefficient enables predictable drift compensation in thermal-aware designs.
The DFN1006BD-2 package features side-wettable flanks for solder joint inspection via AOI, and its 1.0 mm × 0.6 mm footprint supports high-density PCB layouts. Thermal resistance from junction-to-ambient is 340 K/W on standard FR4, limiting continuous power dissipation to 365 mW at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.3 V to 36.7 V at IZ = 2 mA - defines precise regulation point for 36 V rail clamping |
| Differential Resistance (rdif) | 80 Ω typ. at IZ = 2 mA - determines output voltage stability under load transients |
| Reverse Current (IR) | < 0.05 μA at VR = 27 V - ensures negligible leakage in standby mode |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous bias current limit (~10 mA at 36 V) |
| Temperature Coefficient (SZ) | +35 mV/K at IZ = 2 mA - quantifies voltage drift per degree Celsius rise |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction threshold in forward direction |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for automated optical inspection. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-bias path during regulation |
Key Features

| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray |
| ±2 % VZ tolerance | Reduces binning requirements and simplifies reference design margining |
| Ultra-small footprint | 1.0 mm × 0.6 mm area saves >60 % board space vs. traditional SOD-123 packages |
| Low thermal resistance | 340 K/W on FR4 allows higher power density in thermally constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C36-Q | ±5 % tolerance (34.0–38.0 V), higher 90 Ω rdif, +37 mV/K TC | Acceptable where tighter regulation not required; lower cost tier | Select when cost sensitivity outweighs 0.7 % VZ accuracy need |

FAQ
What is the maximum continuous reverse current the BZX884S-B36-QYL can sustain without degradation?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its safe continuous reverse current is limited by power dissipation. At 36 V, the 365 mW rating permits ~10.1 mA average current on FR4 PCB. Exceeding this causes junction temperature rise beyond 150 °C, risking parametric shift or failure.
How does the side-wettable flank feature improve manufacturing yield?
Side-wettable flanks enable automated optical inspection (AOI) of solder fillet formation on the package edges, eliminating reliance on X-ray for void detection. This reduces inspection time by ~40 % and increases first-pass yield in high-volume SMT lines using standard AOI systems calibrated for DFN profiles.
Can BZX884S-B36-QYL replace a 1N4738A in an existing design?
No direct replacement: 1N4738A is a 8.2 V, 1 W through-hole Zener in DO-41 package. BZX884S-B36-QYL is a 36 V, 365 mW DFN device. Voltage, power, package, and thermal behavior differ fundamentally. A redesign of bias network, layout, and thermal relief is required for functional equivalence.
Is the +35 mV/K temperature coefficient linear across the full operating range?
The +35 mV/K value is specified at IZ = 2 mA and Tj = 25 °C. Actual coefficient varies nonlinearly with current and temperature-Fig. 5 and Fig. 6 in the datasheet show it decreases toward zero near 5 V and rises above +50 mV/K above 68 V. For BZX884S-B36-QYL, variation remains within ±5 mV/K from −40 °C to +125 °C.
