Product details
Overview
BZX884S-C30-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in compact automotive and industrial circuits. It delivers a nominal 30 V Zener voltage with ±5 % tolerance, 70 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C30-QYL datasheet, BZX884S-C30-QYL pinout, BZX884S-C30-QYL application, or BZX884S-C30-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low reverse leakage (≤0.05 μA at VR = 28 V).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and supply fluctuations. Its 30 V nominal Zener voltage is specified at IZ = 2 mA, with a temperature coefficient of +21 mV/K - indicating positive drift over temperature - and a typical capacitance of 50 pF at 1 MHz and 0 V bias.
The device uses silicon planar technology with metallization optimized for low thermal resistance (Rth(j-a) = 340 K/W on standard FR4), enabling reliable operation under transient overvoltage conditions in automotive ECUs and sensor signal conditioning paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V nominal, ±5 % tolerance - ensures stable reference within 28.0–32.0 V at IZ = 2 mA |
| Differential Resistance (rdif) | 70 Ω typical at IZ = 2 mA - limits output voltage variation under load current changes |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - defines maximum continuous steady-state power handling in standard layout |
| Reverse Leakage (IR) | ≤0.05 μA at VR = 28 V - enables low-power standby regulation without significant quiescent loss |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports bidirectional protection or dual-use in clamp+bias configurations |
| Junction Temperature (Tj) | −55 °C to +150 °C - certified for under-hood automotive environments per AEC-Q101 |
| Package | DFN1006BD-2 (SOD882BD), 1.0 × 0.6 × 0.47 mm - ultra-small footprint with side-wettable flanks for solder joint inspection |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless 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 must be observed for correct Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield |
| Ultra-small footprint | 1.0 mm × 0.6 mm area saves board space in dense layouts such as camera modules and radar transceivers |
| Wide operating temperature | −55 °C to +150 °C ambient range supports deployment in extreme thermal environments |
| Low capacitance | 50 pF at 1 MHz - minimizes high-frequency loading in signal path references and RF bias networks |
Applications
| Automotive Sensor Reference | Industrial Power Rail Clamp |
|---|---|
Use Scenario: Providing stable 30 V reference for analog front-end circuits in ABS wheel speed sensors. IC Role / Device Role / Timing Role: Zener voltage reference establishing precise bias point for op-amp comparators and ADC input scaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B30-Q | ±2 % tolerance (29.4–30.6 V), higher rdif (80 Ω), same package and AEC-Q101 rating | Better voltage stability for precision references; less suitable for wide-tolerance clamping | Select when tighter regulation (±2 %) is required and cost premium is acceptable |
| MMSZ5258ET1G | 30 V nominal, ±5 %, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, non-AEC-Q101 | Larger footprint, higher power, but lacks automotive qualification and side-wettable flanks | Choose for non-automotive industrial use where board space is less constrained and AOI is not required |
Compared with BZX884S-C30-QYL, the BZX884S-B30-Q offers tighter voltage control at the expense of higher dynamic impedance, while MMSZ5258ET1G trades miniaturization and automotive compliance for higher power handling in legacy packages.

FAQ
What is the marking code for BZX884S-C30-QYL?
The official marking code for BZX884S-C30-QYL is '4M', laser-etched on the top surface of the DFN1006BD-2 package. The marking bar adjacent to pin 1 identifies the cathode terminal, and the code is verified in Table 4 of the Nexperia datasheet Rev. 2 (May 2021).
Can BZX884S-C30-QYL replace BZX884S-B30-Q in an existing design?
Yes, but with trade-offs: both share identical package, thermal specs, and AEC-Q101 qualification, yet BZX884S-C30-QYL has looser ±5 % tolerance (28.0–32.0 V) versus BZX884S-B30-Q's ±2 % (29.4–30.6 V). Differential resistance is lower (70 Ω vs. 80 Ω), improving regulation under load, but voltage accuracy degrades by ±3 %.
What is the maximum reverse current at 28 V for BZX884S-C30-QYL?
At VR = 28 V and Tj = 25 °C, the reverse current is guaranteed ≤0.05 μA, as confirmed in Table 9 of the datasheet. This ultra-low leakage ensures minimal power loss in always-on bias networks and preserves battery life in low-duty-cycle systems.
Does BZX884S-C30-QYL require derating above 70 °C ambient?
Yes - total power dissipation must be linearly derated above 70 °C ambient. With Rth(j-a) = 340 K/W, the allowable Ptot decreases by 1.07 mW/°C beyond 70 °C, reaching zero at 173 °C. Full 365 mW is only valid at Tamb ≤ 70 °C on standard FR4 with 70 μm copper.
