Product details
Overview
BZX884S-C9V1-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in low-power circuits. It provides a nominal 9.1 V breakdown voltage with ±5 % tolerance, 40 Ω typical differential resistance at IZ = 5 mA, and operates up to 365 mW total power dissipation on FR4 PCB. It is AEC-Q101 qualified for automotive body electronics and ECU biasing applications.
For engineers reviewing the BZX884S-C9V1-QYL datasheet, BZX884S-C9V1-QYL pinout, BZX884S-C9V1-QYL application, or BZX884S-C9V1-QYL equivalent, this page delivers verified package dimensions, cathode/anode terminal mapping, thermal resistance (340 K/W), temperature coefficient (+3.8 mV/K), and automotive-grade reliability data - all critical for board-level validation and long-lifecycle design.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load current (IZ = 0.5–5 mA). Its 9.1 V nominal Zener voltage is specified at Tj = 25 °C with a positive temperature coefficient of +3.8 mV/K, indicating voltage increases linearly with junction temperature - a key factor in thermal drift compensation.
The device uses a planar epitaxial process and is housed in a DFN1006BD-2 (SOD882BD) package with side-wettable flanks, enabling automated optical solder-joint inspection. Its 0.65 mm pitch, 1.0 mm × 0.6 mm footprint, and 0.47 mm height support ultra-dense PCB layouts while meeting AEC-Q101 stress test requirements for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, ±5 % tolerance - defines precise clamping/reference level for 5–10 mA operating range |
| Differential Resistance (rdif) | 40 Ω typical at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Temperature Coefficient (SZ) | +3.8 mV/K at IZ = 5 mA - quantifies voltage drift per degree rise; enables thermal error budgeting |
| Max Power Dissipation (Ptot) | 365 mW on FR4, 70 μm Cu - sets absolute thermal limit for continuous operation without derating |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - ensures low-loss forward conduction during transient overvoltage events |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments and industrial enclosures |
| Reverse Current (IR) | ≤0.5 μA at VR = 7.2 V - guarantees minimal leakage below knee voltage, critical for low-power standby circuits |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small plastic package with side-wettable flanks; 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker (bar) aligns with this terminal for visual orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-bias path enabling Zener breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including body control modules and sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B9V1-Q | Same 9.1 V nominal, but ±2 % tolerance and lower rdif (30 Ω typ.) | Used where tighter regulation (<±180 mV) and lower dynamic impedance are required | Select when reference accuracy dominates cost; B-series adds ~12 % unit cost vs. C-series |
| MMSZ5240B-7-F | 9.1 V, ±5 %, but SOD-123 package (2.7 mm × 1.4 mm), higher rdif (60 Ω), no AEC-Q101 | Suitable for non-automotive consumer or industrial boards with less stringent size/qualification needs | Choose only if legacy footprint compatibility or distributor stock availability outweighs miniaturization and automotive compliance |
Compared with BZX884S-C9V1-QYL, the BZX884S-B9V1-Q improves regulation accuracy and dynamic response at higher cost, while MMSZ5240B-7-F sacrifices size, thermal performance, and automotive qualification for broader commercial availability - making the C9V1-QYL optimal for cost-sensitive, space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the maximum continuous reverse current (IZ) this Zener can handle?
The BZX884S-C9V1-QYL is rated for a maximum forward current of 200 mA, but its Zener operation is defined at test currents of 0.5 mA to 5 mA. At 5 mA, it delivers stable 9.1 V regulation with 40 Ω differential resistance; sustained operation above 10 mA requires thermal derating per the 365 mW Ptot limit on FR4 PCB.
Does the side-wettable flank (SWF) feature require special stencil or reflow profile?
No special stencil is required - standard 0.12 mm laser-cut stencils with 1:1 aperture ratio work reliably. Reflow must follow JEDEC J-STD-020 profiles for MSAL3 moisture sensitivity level; peak temperature ≤260 °C is mandatory. The SWF geometry ensures consistent solder fillet formation visible under AOI without altering thermal ramp rates.
How does the +3.8 mV/K temperature coefficient affect long-term voltage stability?
Over a −40 °C to +125 °C ambient range, the Zener voltage shifts approximately +630 mV - from 8.47 V to 9.10 V. This predictable linear drift enables software-based compensation in microcontroller-based systems or selection of complementary components (e.g., NTC thermistors) in analog circuits to achieve <±0.5 % total variation.
Can this diode replace older BZX85 or BZX79 series in existing designs?
Direct replacement is not recommended due to package mismatch (SOD882BD vs. DO-35/DO-41) and different thermal characteristics. While electrical parameters overlap, the DFN1006BD-2's 340 K/W Rth(j-a) demands revised layout rules - including copper pour area and via placement - to replicate the thermal performance of through-hole predecessors.
