Product details
Overview
BZX884S-B22-QYL from Nexperia is a ±2 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision voltage regulation at 22 V nominal breakdown voltage with 200 mA maximum forward current and 365 mW power dissipation. It is AEC-Q101 qualified and used in automotive power rail stabilization and low-power reference circuits.
For engineers reviewing the BZX884S-B22-QYL datasheet, BZX884S-B22-QYL pinout, BZX884S-B22-QYL application, or BZX884S-B22-QYL equivalent, key selection criteria include Zener voltage tolerance (±2 %), side-wettable flank compatibility for automated optical inspection (AOI), thermal resistance (340 K/W), and differential resistance (60 Ω at IZ = 5 mA).
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a nominal VZ of 22 V (21.6–22.4 V range at IZ = 5 mA) and exhibits a positive temperature coefficient of +15.4 mV/K at that current. Its low 60 Ω differential resistance ensures stable regulation under varying load conditions.
The device uses a planar silicon junction structure optimized for low leakage (≤0.05 μA at VR = 17.6 V) and low capacitance (60 pF at 1 MHz, VR = 0 V), enabling use in noise-sensitive analog references and ESD-robust bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 22 V - precise regulation point for 24 V rail clamping or reference generation |
| VZ Tolerance | ±2 % - tight tolerance enables accurate voltage setting without trimming |
| IF Max | 200 mA - supports robust surge current handling during transient events |
| Ptot | 365 mW - power rating on standard FR4 PCB with 70 μm copper, defines thermal design margin |
| rdif | 60 Ω at IZ = 5 mA - low dynamic impedance maintains regulation stability across load variations |
| Tj Max | 150 °C - junction temperature limit compatible with under-hood automotive environments |
| Cd | 60 pF at 1 MHz - minimal parasitic capacitance preserves high-frequency signal integrity in bias networks |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm body, side-wettable flanks for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-bias polarity required for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on ultra-compact 0402-equivalent footprint |
| Low differential resistance | 60 Ω at 5 mA ensures <132 mV output variation over ±1 mA load change |
| Wide operating temperature | −55 °C to +150 °C ambient range supports engine control unit (ECU) and ADAS module deployment |
| Low reverse leakage | ≤0.05 μA at 17.6 V enables microamp-level standby current budgets in always-on circuits |
Applications
| Automotive Power Rail Clamping | Low-Power Analog Reference |
|---|---|
Use Scenario: Stabilizing 24 V supply rails in body control modules against load dump transients. IC Role / Device Role / Timing Role: Zener diode acting as shunt regulator and overvoltage clamp. Use Value: 22 V breakdown with ±2 % tolerance ensures clamping occurs before downstream IC damage thresholds (typically 28 V). | Use Scenario: Providing stable bias voltage for op-amp input stages in battery monitoring ICs. IC Role / Device Role / Timing Role: Precision voltage reference source in low-current (<1 mA) analog front-ends. Use Value: 60 Ω rdif and 0.05 μA IR minimize error contribution and quiescent current draw. |
| ESD-Protected Sensor Biasing | Industrial PLC Input Protection |
Use Scenario: Biasing and protecting thermistor or RTD sensor bridges in harsh industrial environments. IC Role / Device Role / Timing Role: Dual-role device providing DC bias and transient suppression via Zener action. Use Value: Side-wettable flanks ensure reliable solder joints critical for long-term field reliability; 150 °C Tj max supports extended thermal cycling life. | Use Scenario: Protecting 24 V digital input channels in programmable logic controllers against surges and miswiring. IC Role / Device Role / Timing Role: Primary shunt protection element placed before optocoupler input stage. Use Value: 365 mW Ptot and 200 mA IF max enable absorption of IEC 61000-4-5 Level 3 surges without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C22-Q | ±5 % tolerance (vs. ±2 %); higher rdif (70 Ω); same package and VZ range | Less suitable for precision references; acceptable for general-purpose clamping | Select when cost sensitivity outweighs regulation accuracy requirements |
| MMSZ5247B-TP | ±5 % tolerance; SOD-123 package (larger footprint); 350 mW Ptot; 22 V nominal | Not AOI-compatible due to non-side-wettable leads; requires rework of PCB layout | Choose only if legacy SOD-123 footprint must be retained and automotive qualification is not required |
Compared with BZX884S-B22-QYL, the BZX884S-C22-Q trades regulation accuracy for cost, while MMSZ5247B-TP sacrifices AOI capability and AEC-Q101 compliance for broader distributor availability-making the QYL variant optimal for new automotive designs requiring precision and manufacturability.

FAQ
What is the maximum reverse voltage (VR) before breakdown for BZX884S-B22-QYL?
The nominal Zener voltage is 22 V, with a guaranteed breakdown range of 21.6 V to 22.4 V at IZ = 5 mA. Below 17.6 V, reverse leakage remains ≤0.05 μA per datasheet Table 8. Operation below VZ is non-regulating; the device functions only as a low-leakage diode until reaching its specified breakdown threshold.
Can BZX884S-B22-QYL be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients at low voltages but positive above ~5.6 V; BZX884S-B22-QYL has +15.4 mV/K, causing thermal runaway if paralleled without individual ballast resistors. For >365 mW needs, use a single higher-rated device or active regulation instead.
Is the cathode marking visible under standard optical inspection?
Yes-the cathode is indicated by a laser-marked bar on the top surface, aligned with Pin 1 per Figure 10 and Table 2. The DFN1006BD-2 package's side-wettable flanks further enable automated X-ray and AOI verification of solder fillet formation on both terminals.
Does BZX884S-B22-QYL require derating at elevated ambient temperatures?
Yes-thermal resistance is 340 K/W (junction-to-ambient, FR4 PCB). At 100 °C ambient, maximum allowable power drops to ~215 mW to maintain Tj ≤ 150 °C. Derating curves are provided in Nexperia's thermal application notes for SOD882BD packages.
