Product details
Overview
BZX884S-C7V5-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 7.5 V Zener voltage with ±5 % tolerance, 30 Ω typical differential resistance at IZ = 5 mA, 5.3 mV/K temperature coefficient, and operates within −55 °C to +150 °C ambient range.
For engineers reviewing the BZX884S-C7V5-QYL datasheet, BZX884S-C7V5-QYL pinout, BZX884S-C7V5-QYL application, or BZX884S-C7V5-QYL equivalent, this device supports high-reliability voltage clamping in space-constrained PCBs where AEC-Q101 qualification, side-wettable flanks for solder inspection, and low capacitance (150 pF at 1 MHz) are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its 7.5 V nominal Zener voltage is specified at 5 mA test current, with a tight 30 Ω typical dynamic impedance ensuring minimal output voltage deviation under load transients.
The device features an AEC-Q101-qualified DFN1006BD-2 (SOD882BD) package with side-wettable flanks for automated optical solder-joint inspection, and exhibits a positive temperature coefficient of +5.3 mV/K - enabling predictable thermal drift compensation in multi-diode reference networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal, ±5 % tolerance - ensures regulated reference within 7.0–7.9 V at IZ = 5 mA |
| Differential Resistance (rdif) | 30 Ω typical at IZ = 5 mA - limits output voltage variation to ~150 mV per 5 mA load change |
| Temperature Coefficient (SZ) | +5.3 mV/K at IZ = 5 mA - enables predictable thermal drift for biasing or compensation circuits |
| Reverse Current (IR) | ≤1 μA at VR = 5.3 V - guarantees low leakage in standby or low-power monitoring paths |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - supports continuous regulation up to ~48 mA at 7.5 V without heatsinking |
| Junction Temperature (Tj) | 150 °C maximum - enables operation in under-hood automotive environments and sealed industrial enclosures |
| Capacitance (Cd) | 150 pF at f = 1 MHz, VR = 0 V - minimizes signal coupling in high-frequency sensing or RF-adjacent circuits |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar on top surface identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain, body control, and ADAS modules requiring zero-failure reliability |
| Side-wettable flanks (SWF) | Enables automated X-ray or AOI solder-joint verification without cross-sectioning - critical for high-volume SMT lines |
| Low dynamic impedance | 30 Ω typical ensures <±0.15 V regulation error over ±5 mA load step, improving ADC reference stability |
| Wide operating temperature | −55 °C to +150 °C ambient range supports deployment in engine compartments and industrial motor drives |
| Ultra-compact footprint | DFN1006BD-2 saves >70 % board area vs. traditional SOD-323 packages - ideal for wearables and sensor nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B7V5-Q | Same package and pinout; tighter ±2 % VZ tolerance (7.35–7.65 V), higher 6 Ω rdif | Better regulation accuracy required in precision ADC references or calibration circuits | Select when absolute voltage accuracy outweighs cost sensitivity; requires tighter layout control due to lower rdif |
| MMSZ5236B-7-F | SOD-123 package (2.7 × 1.6 mm); ±5 % VZ, 30 Ω rdif, but no AEC-Q101 qualification | Non-automotive consumer or industrial designs where board space is less constrained | Choose only for non-automotive use; lacks SWF and automotive qualification - unsuitable for OEM production |
Compared with BZX884S-C7V5-QYL, the BZX884S-B7V5-Q offers superior voltage accuracy at the expense of slightly higher cost and identical thermal performance, while MMSZ5236B-7-F trades automotive reliability and miniaturization for legacy package compatibility and broader distributor availability.

FAQ
What is the maximum reverse current specification for BZX884S-C7V5-QYL at its rated Zener voltage?
At VR = 5.3 V (70 % of nominal 7.5 V), the maximum reverse current is 1 μA. This low leakage ensures minimal power loss in always-on monitoring circuits and preserves signal integrity in high-impedance sensor interfaces without introducing measurable offset errors.
Can BZX884S-C7V5-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, minor VZ mismatches cause current hogging. The BZX884S-C7V5-QYL is rated for 365 mW single-device operation; parallel use risks thermal runaway and premature failure without individual ballast resistors.
Does the side-wettable flank feature require special stencil or reflow profile adjustments?
No - the DFN1006BD-2 package uses standard reflow soldering with industry-standard profiles. Side-wettable flanks are geometrically integrated into the terminal design and do not alter thermal mass or solder paste requirements; they simply expose solder fillets for automated optical inspection post-reflow.
How does the +5.3 mV/K temperature coefficient impact long-term voltage reference stability?
The +5.3 mV/K coefficient means VZ increases by ~38 mV over a 70 °C rise (e.g., −40 °C to +30 °C ambient). For applications demanding <0.5 % total drift, this must be compensated via circuit topology (e.g., complementary diode pairs) or calibrated in firmware - it is not inherently unstable, but predictable and quantifiable.
