Product details
Overview
BZX884S-C43-QYL from Nexperia is a ±5 % tolerance Zener diode in SOD882BD (DFN1006BD-2) package, rated for 43 V nominal breakdown voltage at 2 mA, 365 mW power dissipation, and qualified to AEC-Q101 for automotive voltage regulation and overvoltage protection circuits.
For engineers reviewing the BZX884S-C43-QYL datasheet, BZX884S-C43-QYL pinout, BZX884S-C43-QYL application, or BZX884S-C43-QYL equivalent, this part supports precision clamping in low-power sensor interfaces, ESD-protected I/O rails, and compact DC bias networks where side-wettable flanks enable automated optical inspection of solder joints.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a typical differential resistance of 85 Ω at 2 mA test current and a temperature coefficient of +45 mV/K - indicating positive thermal drift optimized for stable reference generation across −55 °C to +150 °C ambient range.
Its ultra-small DFN1006BD-2 footprint (1.0 mm × 0.6 mm × 0.47 mm) features side-wettable flanks for reliable reflow solder joint inspection, and it delivers <0.05 μA reverse leakage at 34.4 V (80 % of VZ) per characterization data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 40.0 V to 46.0 V at IZ = 2 mA; ensures ±5 % tolerance compliance for mid-range voltage clamping |
| Differential Resistance rdif | 85 Ω typ. at IZ = 2 mA; defines dynamic impedance during regulation, critical for noise rejection in reference paths |
| Temperature Coefficient SZ | +45 mV/K at IZ = 2 mA; quantifies VZ drift with junction temperature, enabling thermal error budgeting |
| Max Power Dissipation Ptot | 365 mW on FR4 PCB with 70 μm copper; sets absolute thermal limit for continuous operation in unheatsinked layouts |
| Reverse Leakage IR | ≤0.05 μA at VR = 34.4 V; guarantees minimal standby current in high-impedance bias networks |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA; confirms low conduction loss when used in forward-biased protection or logic-level detection |
| Junction Temperature Tj | −55 °C to +150 °C; validated operating range supporting under-hood automotive and industrial environments |
Pinout & Package
Package: SOD882BD (DFN1006BD-2), leadless 2-terminal surface-mount plastic package with side-wettable flanks, 0.65 mm pitch, 1.0 mm × 0.6 mm × 0.47 mm body; marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |

| Low thermal resistance Rth(j-a) | 340 K/W on standard FR4; allows 365 mW dissipation without external heatsinking in ambient ≤85 °C |
Applications
| Automotive Sensor Biasing | Industrial I/O Protection |
|---|---|
Use Scenario: Providing stable 43 V bias to MEMS pressure sensor bridge in engine control unit. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference and overvoltage clamp during load dump transients. Use Value: Maintains sensor excitation within ±5 % across −40 °C to +125 °C, while surviving 120 V/50 ms load dump pulses via energy absorption. |
Use Scenario: Clamping analog input pins of PLC analog-to-digital converter against field-induced surges. IC Role / Device Role / Timing Role: Passive shunt regulator limits input voltage to 43 V, protecting downstream ADC front-end from damage. Use Value: Limits transient overshoot to safe levels with <0.05 μA leakage at 34.4 V, preserving signal integrity in high-impedance measurement paths. |
| Portable Medical Device Power Rail | Consumer USB-C PD Interface |
Use Scenario: Regulating auxiliary 43 V rail for piezoelectric actuator driver in handheld ultrasound probe. IC Role / Device Role / Timing Role: Zener stabilizes supply to gate driver IC during battery voltage sag, ensuring consistent actuation timing. Use Value: Delivers 85 Ω dynamic impedance at 2 mA, minimizing output ripple under pulsed load conditions up to 200 mA peak. |
Use Scenario: Protecting CC line voltage supervisor IC from VBUS coupling during USB-C hot-plug events. IC Role / Device Role / Timing Role: Fast-acting clamp absorbs 100 ns rise-time transients on CC line before they reach supervisor logic. Use Value: Achieves <100 ns response time due to low junction capacitance (40 pF at 0 V), preventing false PD contract negotiation failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B43-Q | ±2 % VZ tolerance (42.1 V–43.9 V) vs. ±5 % (40.0 V–46.0 V); otherwise identical package, power rating, and thermal specs | Required where tighter regulation stability is needed for precision references; not suitable if cost sensitivity dominates | Select BZX884S-B43-Q only when system-level calibration tolerances demand sub-1 % total error budget. |
| MMSZ43-Q | SOD-123 package (2.7 mm × 1.4 mm), higher Rth(j-a) (400 K/W), same 43 V nominal VZ and ±5 % tolerance | Preferred where legacy board designs prohibit DFN1006BD-2 footprint change or require manual rework compatibility | Choose MMSZ43-Q only when retrofitting existing SOD-123 footprints; avoid in new designs targeting miniaturization. |
Compared with BZX884S-C43-QYL, the BZX884S-B43-Q offers tighter voltage control at higher cost, while the MMSZ43-Q trades size and thermal performance for backward compatibility - making the C-series optimal for new automotive and industrial designs prioritizing miniaturization and AOI capability.

FAQ
What is the maximum reverse current at 80 % of nominal Zener voltage?
At VR = 34.4 V (80 % of 43 V), the reverse leakage current is ≤0.05 μA per Table 9 of the datasheet. This value is measured at Tj = 25 °C and confirms minimal standby power draw in high-impedance bias networks.
Can BZX884S-C43-QYL be used in place of a 43 V Zener in an existing SOD-323 design?
No - BZX884S-C43-QYL uses the SOD882BD (DFN1006BD-2) package, which is physically incompatible with SOD-323 footprints. Its 1.0 mm × 0.6 mm body and 0.65 mm pitch require PCB redesign; use MMSZ43-Q for SOD-123 or BZX384-C43 for SOD-323 compatibility.
How does the +45 mV/K temperature coefficient affect regulation accuracy over temperature?
With +45 mV/K, VZ increases ~1.13 V over a 25 °C to 125 °C junction temperature swing. For applications requiring <±1 % regulation, this drift must be compensated in system-level calibration or mitigated using temperature-stable reference architectures.
Is reflow soldering the only recommended assembly method?
Yes - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" for the SOD882BD package. Wave or hand soldering risks thermal damage due to the small thermal mass and side-wettable flank geometry, potentially compromising solder joint integrity and reliability.
