Product details
Overview
BZX884S-C75-QYL from Nexperia is a 75 V ±5 % tolerance Zener diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and overvoltage protection in automotive-grade power rails. It delivers 365 mW total power dissipation at 25 °C, exhibits 170 Ω typical differential resistance at 2 mA, and features side-wettable flanks for reliable automated optical inspection (AOI) in high-volume SMT assembly.
For engineers reviewing the BZX884S-C75-QYL datasheet, BZX884S-C75-QYL pinout, BZX884S-C75-QYL application, or BZX884S-C75-QYL equivalent, this page provides verified technical context, AEC-Q101 qualification status, thermal resistance (340 K/W), reverse current limits (<0.05 μA at 57 V), and real-world design meaning for voltage reference stability in engine control units and ADAS sensor supplies.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 75 V reference across varying load currents (IZ = 2 mA typical). Its temperature coefficient of +95 mV/K ensures predictable drift behavior under thermal stress, critical for automotive ambient ranges (−55 °C to +150 °C).
The DFN1006BD-2 package enables ultra-compact placement with 0.65 mm pitch and side-wettable flanks-supporting IPC-A-610 Class 3 solder joint verification. Junction-to-ambient thermal resistance is 340 K/W on standard FR4, limiting continuous power handling without derating above 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 75 V nominal, ±5 % tolerance - defines clamping threshold for overvoltage protection in 60–80 V systems. |
| Differential Resistance (rdif) | 170 Ω typ. at IZ = 2 mA - determines output impedance and regulation error under load variation. |
| Reverse Current (IR) | <0.05 μA at VR = 57 V - ensures minimal leakage in standby mode for battery-sensitive applications. |
| Total Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C - sets maximum continuous DC power before thermal shutdown or degradation. |
| Junction Temperature (Tj) | 150 °C max - enables operation in under-hood environments with sustained high-temperature exposure. |
| Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies self-heating rise per watt; requires PCB copper area planning for thermal management. |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), 2-terminal leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal during visual inspection. |
| 2 | Anode (A) | Connected to ground or low-impedance return path; reverse-biased configuration enables Zener operation. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity bias, and high-temperature reverse bias testing. |
| Ultra-small footprint | 0.6 mm² board area saves space in dense ECUs and camera modules where PCB real estate is constrained. |
| ±5 % voltage tolerance | Supports cost-optimized designs where tighter regulation is unnecessary, balancing accuracy and BOM cost. |
| Low reverse leakage | <0.05 μA at 76 % of VZ ensures minimal quiescent current draw in always-on vehicle subsystems. |
Applications
| Engine Control Unit (ECU) Reference | ADAS Camera Power Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B75-Q | Same package and 75 V nominal rating, but ±2 % tolerance (tighter than C-series ±5 %). | Used where higher voltage accuracy is required, e.g., calibration-critical instrumentation front-ends. | Select when reference stability <±15 mV is mandatory; accept ~15 % higher unit cost and lower stock availability. |
| MMSZ5265ET1G | 75 V Zener, SOD-123 package (2.7 × 1.6 mm), ±5 %, 500 mW Ptot, no AEC-Q101 qualification. | Suitable for industrial or consumer power supplies where automotive reliability is not mandated. | Choose for non-automotive designs needing higher power margin; avoid in vehicle platforms requiring AEC compliance. |
Compared with BZX884S-C75-QYL, the BZX884S-B75-Q offers tighter voltage control at the expense of cost and availability, while MMSZ5265ET1G trades AEC-Q101 validation and miniaturization for higher power handling and broader commercial distribution.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX884S-C75-QYL has a nominal Zener voltage of 75 V with ±5 % tolerance, meaning its guaranteed breakdown range is 70 V to 79 V at IZ = 2 mA. It is rated for continuous operation up to 75 V and can safely clamp transients exceeding that level only within its 365 mW power limit and thermal constraints.
Does this part support reflow soldering on standard FR4 PCBs?
Yes - the DFN1006BD-2 package is qualified for lead-free reflow soldering using standard JEDEC profiles. The side-wettable flanks enable full solder fillet formation visible under AOI, and thermal resistance data (340 K/W) assumes mounting on single-sided 70 μm tin-plated FR4 with standard footprint per Figure 11 in the datasheet.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
At 75 V, the BZX884S-C75-QYL has a typical temperature coefficient of +95 mV/K. Over −40 °C to +125 °C (165 K span), this results in ~15.7 mV total drift - approximately ±0.21 % of nominal VZ. This is acceptable for non-precision clamping but insufficient for metrology-grade references without compensation.
Is there a recommended PCB footprint or layout guidance for thermal performance?
The datasheet specifies a reflow footprint with 0.7 mm solder lands (2×), 0.4 mm solder resist opening, and 1.3 mm overall length. To achieve the rated 340 K/W Rth(j-a), use minimum 10 mm² of 70 μm copper pour connected directly to both terminals, avoiding thermal isolation from adjacent ground planes.
