Product details
Overview
BZX884S-C39-QYL from Nexperia is a ±5 % tolerance Zener diode in DFN1006BD-2 (SOD882BD) package, rated for 39 V nominal breakdown voltage at 2 mA, with 80 Ω typical differential resistance and 40 mV/K temperature coefficient. It delivers stable voltage regulation in automotive power supply monitoring and ECU reference circuits.
For engineers reviewing the BZX884S-C39-QYL datasheet, BZX884S-C39-QYL pinout, BZX884S-C39-QYL application, or BZX884S-C39-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and 37 V reverse working voltage compliance.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 39 V reference under varying load and temperature conditions. Its 80 Ω differential resistance ensures minimal output voltage drift across 1–5 mA test currents, while the +40 mV/K temperature coefficient enables predictable thermal behavior in ambient ranges from −55 °C to +150 °C.
Designed for surface-mount use on single-sided FR4 PCBs with 70 μm tin-plated copper, it leverages side-wettable flanks for solder joint integrity verification. The device meets AEC-Q101 stress testing requirements including HTGB, HTRB, and TCT, confirming suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 37.0 V to 41.0 V at IZ = 2 mA - defines usable regulation window for precision 39 V references |
| Differential Resistance (rdif) | 80 Ω typical at IZ = 2 mA - limits output voltage variation under load current changes |
| Temperature Coefficient (SZ) | +40 mV/K at IZ = 2 mA - quantifies positive VZ drift per degree Celsius rise |
| Reverse Current (IR) | ≤ 0.05 μA at VR = 30 V - ensures low leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC power handling under standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in engine control and transmission modules |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-compact footprint with side-wettable flanks for AOI |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless, two-terminal surface-mount package with side-wettable flanks, 0.65 mm pitch, and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker determines forward conduction direction and Zener breakdown orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Side-wettable flanks | Enables automated optical inspection of solder joints without X-ray, improving manufacturing yield |
| ±5 % voltage tolerance | Supports cost-sensitive designs where tighter tolerance is not required for functional safety margins |
| Ultra-small footprint | 1.0 mm × 0.6 mm area reduces PCB real estate in space-constrained modules like ADAS sensors |
| Low thermal resistance | Rth(j-a) = 340 K/W on FR4 - allows reliable operation up to 150 °C junction temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B39-Q | ±2 % tolerance (38.2–39.8 V), 40 Ω rdif, +30 mV/K SZ | Narrower regulation band improves accuracy in feedback loops but increases cost | Select when closed-loop stability requires <±0.5 % reference error budget |
| MMSZ5241B-TP | ±5 % tolerance (37.1–40.9 V), 90 Ω rdif, +42 mV/K SZ, SOD-123 package | Larger 2.7 mm × 1.6 mm footprint lacks side-wettable flanks | Choose for legacy board rework where DFN retooling is impractical |
Compared with BZX884S-C39-QYL, the BZX884S-B39-Q offers tighter voltage control at higher cost and lower thermal resistance, while MMSZ5241B-TP trades miniaturization and AOI capability for broader industry familiarity and easier hand-soldering.

FAQ
What is the maximum continuous reverse current this Zener can handle before thermal failure?
The absolute maximum forward current is 200 mA, but for Zener operation, the limiting factor is power dissipation. At 39 V, the device sustains ≤9.4 mA continuously (365 mW ÷ 39 V) on a standard FR4 PCB. Exceeding this causes junction temperature to exceed 150 °C, risking parametric shift or catastrophic failure.
Does the side-wettable flank design require special stencil or reflow profile adjustments?
No special stencil is needed - standard 0.12 mm laser-cut stainless steel stencils with 1:1 aperture ratio are sufficient. Reflow must follow JEDEC J-STD-020 profile for MSAL3 moisture sensitivity level, with peak temperature ≤260 °C and time above liquidus 60–90 seconds, as validated in Nexperia's SOD882BD soldering guidelines.
How does the +40 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over that 165 K range, VZ shifts +6.6 V (40 mV/K × 165 K), resulting in a total regulation band of 37–47.6 V. This is acceptable for non-critical monitoring functions but requires compensation in precision references - e.g., pairing with a negative-TC resistor network or using in conjunction with an op-amp error amplifier.
Can this part replace older BZX84-C39 in existing designs?
Yes, with caveats: BZX884S-C39-QYL uses DFN1006BD-2 (1.0 × 0.6 mm), while BZX84-C39 uses SOT-23 (3.0 × 1.4 mm). Footprint redesign is mandatory. Electrical specs are comparable (both ±5 %, ~39 V), but the newer part offers AEC-Q101 qualification, lower Rth(j-a), and side-wettable flanks - making it superior for new automotive designs.
