Product details
Overview
BZX884S-B75-QYL from Nexperia is a 75 V ±2 % tolerance Zener diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and overvoltage protection in automotive-grade circuits. It delivers 365 mW power dissipation at 25 °C, exhibits 170 Ω typical differential resistance at IZ = 2 mA, and maintains stable operation from −55 °C to +150 °C ambient.
For engineers reviewing the BZX884S-B75-QYL datasheet, BZX884S-B75-QYL pinout, BZX884S-B75-QYL application, or BZX884S-B75-QYL equivalent, this device is selected for high-reliability 75 V reference and clamping functions where AEC-Q101 qualification, side-wettable flanks for automated optical inspection, and ultra-small 1.0 mm × 0.6 mm footprint are critical design requirements.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 75 V at IZ = 2 mA, exhibiting a positive temperature coefficient of +95 mV/K across its operating current range. Its low 35 pF capacitance at 0 V and 1 MHz enables use in noise-sensitive analog references and fast transient suppression.
The device uses silicon planar epitaxial construction and is qualified per AEC-Q101 for automotive applications. Its thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, limiting maximum steady-state power to 365 mW at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 73.5 V to 76.5 V at IZ = 2 mA - tight ±2 % tolerance ensures accurate 75 V reference in feedback loops and protection thresholds |
| Differential Resistance (rdif) | 170 Ω typical at IZ = 2 mA - defines regulation stiffness and output impedance under load variation |
| Temperature Coefficient (SZ) | +95 mV/K at IZ = 2 mA - quantifies drift rate of VZ with junction temperature change |
| Reverse Current (IR) | ≤0.05 μA at VR = 57 V - specifies leakage level below breakdown, critical for low-power standby circuits |
| Total Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 - sets maximum continuous DC or pulsed power handling on standard PCB layout |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased clamp or ESD path |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments and industrial control enclosures |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless surface-mount, 1.0 mm × 0.6 mm × 0.47 mm body, side-wettable flanks for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output or voltage reference node; polarity must be observed for correct Zener biasing |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units and ADAS power rails |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing defect escape |
| Ultra-small DFN1006BD-2 footprint | 1.0 mm × 0.6 mm area saves PCB space in dense power management and sensor interface modules |
| ±2 % VZ tolerance | Supports tighter regulation margins than ±5 % variants, reducing need for post-production trimming |
| 150 °C max junction temperature | Allows sustained operation in high-temperature zones such as near power converters or motor drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C75-Q | ±5 % tolerance (70 V to 79 V), higher IR (≤0.05 μA same), identical package and thermal specs | Suitable for non-critical biasing where cost sensitivity outweighs regulation precision | Select when ±5 % VZ meets system margin and BOM cost reduction is prioritized |
| MMSZ5265B-TP | 75 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, Rth(j-a) = 300 K/W | Higher power handling but 4.5× larger footprint; lacks AEC-Q101 and side-wettable flanks | Choose only if board space permits larger package and automotive qualification is not required |
Compared with BZX884S-C75-Q, the BZX884S-B75-QYL offers tighter tolerance and automotive qualification at no footprint penalty; versus MMSZ5265B-TP, it trades 135 mW lower power rating for 75 % smaller area and guaranteed automotive reliability.

FAQ
What is the maximum reverse voltage before breakdown for BZX884S-B75-QYL?
The specified Zener voltage range is 73.5 V to 76.5 V at IZ = 2 mA. Breakdown begins gradually above ~70 V, with full regulation established by 73.5 V. The absolute maximum reverse voltage is not defined beyond the 76.5 V upper limit of the tolerance band; operation above this risks parametric shift or failure.
Can BZX884S-B75-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients at low voltages but positive coefficients above ~5.6 V; the BZX884S-B75-QYL has +95 mV/K, causing thermal runaway if paralleled without individual ballast resistors. Its 365 mW rating assumes single-device mounting on standard FR4.
Does the marking bar indicate cathode or anode on the BZX884S-B75-QYL package?
The marking bar on the top surface of the DFN1006BD-2 package identifies Pin 1 as the cathode (K), consistent with Table 2 and Figure 10 in the datasheet. This orientation must be maintained during placement to ensure correct reverse-bias operation.
Is BZX884S-B75-QYL compatible with lead-free reflow profiles?
Yes - the device is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The recommended footprint (Figure 11) and side-wettable flanks support reliable solder joint formation using Type 3 or Type 4 solder paste and standard reflow profiles.
