Product details
Overview
BZX884S-B24-QYL from Nexperia is a 24 V ±2 % tolerance Zener diode in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, designed for precision voltage regulation and reference functions in space-constrained automotive and industrial circuits. It delivers 24 V nominal breakdown at IZ = 5 mA, exhibits 60 Ω typical differential resistance, supports 200 mA maximum forward current, and operates across −55 °C to +150 °C ambient.
For engineers reviewing the BZX884S-B24-QYL datasheet, BZX884S-B24-QYL pinout, BZX884S-B24-QYL application, or BZX884S-B24-QYL equivalent, this device is selected for stable low-power voltage clamping, overvoltage protection, and biasing in ECUs, sensor interfaces, and power supply feedback loops where AEC-Q101 qualification and tight voltage tolerance are required.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 24 V reference under regulated current conditions. Its temperature coefficient of +18.4 mV/K at IZ = 5 mA enables predictable drift compensation in thermal-stable designs, while its 0.05 μA max reverse leakage at VR = 19.2 V ensures minimal standby power loss.
The DFN1006BD-2 package integrates cathode and anode terminals on a 0.65 mm pitch, with side-wettable flanks enabling automated optical solder-joint inspection. Thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, limiting continuous power dissipation to 365 mW at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 23.5 V to 24.5 V at IZ = 5 mA - defines precise clamping threshold for 24 V rail protection |
| Differential Resistance rdif | 60 Ω typical at IZ = 5 mA - determines output impedance and regulation sensitivity to load changes |
| Temperature Coefficient SZ | +18.4 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Reverse Leakage IR | 0.05 μA max at VR = 19.2 V - ensures negligible current draw in standby or high-impedance bias networks |
| Total Power Dissipation Ptot | 365 mW on FR4 PCB - sets maximum continuous power handling without heatsinking |
| Junction Temperature Tj | −55 °C to +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C24-Q | ±5 % tolerance (22.8 V–25.6 V), higher max reverse leakage (0.05 μA vs. same), identical package and thermal specs | Acceptable where cost-sensitive designs tolerate wider regulation window and reduced thermal stability | Select for non-critical biasing where ±2 % is not required and BOM cost reduction is prioritized |
| MMSZ4700T1G | 24 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, 100 Ω rdif, no AEC-Q101 qualification | Larger footprint, higher power handling, but unsuitable for automotive production due to lack of qualification | Use only in commercial-grade power supplies where space and qualification are not constraints |
Compared with BZX884S-B24-QYL, the C24-Q variant trades voltage precision for cost in identical form factor, while MMSZ4700T1G offers higher power but sacrifices automotive compliance and board-space efficiency-making the BZX884S-B24-QYL optimal for AEC-Q101-compliant, space-limited 24 V regulation.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX884S-B24-QYL has a nominal Zener voltage of 24 V with ±2 % tolerance, meaning breakdown occurs between 23.5 V and 24.5 V at IZ = 5 mA. Its absolute maximum reverse voltage is not defined separately-it is rated for continuous operation up to its specified VZ range under controlled current, with 19.2 V reverse test voltage used for leakage verification.
Can this diode be used in forward-bias mode like a standard rectifier?
Yes, it conducts forward current up to 200 mA with a maximum forward voltage of 0.9 V at 10 mA, but it is not optimized for rectification. Its primary function is reverse-bias Zener regulation; forward use is limited to low-current biasing or protection paths where its 0.9 V VF and 365 mW power limit are acceptable.
How does the side-wettable flank feature impact PCB assembly?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder joint quality by imaging solder fillet formation along the vertical sidewalls-eliminating reliance on X-ray for process validation and improving first-pass yield in high-volume automotive PCB assembly.
Is thermal derating required above 25 °C ambient?
Yes. With a thermal resistance of 340 K/W and maximum junction temperature of 150 °C, power dissipation must be linearly derated above 25 °C. At 85 °C ambient, maximum allowable Ptot drops to approximately 240 mW (365 mW − (85 − 25) × 365/340), ensuring Tj remains within safe limits.
