Product details
Overview
BZX884S-B2V7-QYL from Nexperia is a 2.7 V ±2 % Zener voltage regulator diode in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, rated for 365 mW total power dissipation at 25 °C and qualified to AEC-Q101 for automotive use.
For engineers reviewing the BZX884S-B2V7-QYL datasheet, BZX884S-B2V7-QYL pinout, BZX884S-B2V7-QYL application, or BZX884S-B2V7-QYL equivalent, key selection criteria include its tight 2.7 V nominal Zener voltage tolerance, low thermal resistance (340 K/W), cathode-marked side-wettable flank package for automated optical inspection, and verified performance under automotive temperature range (−55 °C to +150 °C).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage across load variations, with differential resistance of 300 Ω at IZ = 5 mA and 600 Ω at IZ = 1 mA. Its temperature coefficient is −3.5 mV/K at 5 mA, enabling predictable drift compensation in precision biasing circuits.
Designed for surface-mounted regulation in space-constrained environments, it features side-wettable flanks for reliable solder-joint inspection and complies with AEC-Q101 stress testing-ensuring robustness in automotive ECU, sensor interface, and power-rail monitoring applications where long-term stability and thermal resilience are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 2.7 V nominal, ±2 % tolerance - ensures precise 2.65–2.75 V regulation at IZ = 5 mA for stable reference generation |
| Power dissipation Ptot | 365 mW at Tamb = 25 °C on FR4 PCB - defines maximum continuous DC or pulsed power handling in standard layout |
| Differential resistance rdif | 300 Ω (typ) at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Forward voltage VF | ≤0.9 V at IF = 10 mA - enables low-loss forward conduction during transient clamping or polarity protection |
| Junction temperature Tj | 150 °C max - sets upper thermal limit for operation in high-ambient automotive or industrial environments |
| Reverse leakage IR | 20 μA max at VR = 1 V - guarantees minimal quiescent current in standby or low-power bias networks |
| Package | DFN1006BD-2 (SOD882BD), 1.0 × 0.6 × 0.47 mm - ultra-compact footprint with side-wettable flanks for AOI-compatible reflow assembly |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and marking bar indicating cathode. Dimensions: 1.0 mm × 0.6 mm × 0.47 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar on top surface identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape |
| ±2 % Zener tolerance | Supports tighter voltage margining in safety-critical bias networks versus ±5 % variants |
| Low thermal resistance | Rth(j-a) = 340 K/W on standard FR4 - improves power derating capability in compact PCB layouts |
| Ultra-small footprint | 0.6 mm width allows placement in dense routing zones, such as near microcontroller voltage monitors or CAN transceiver references |
Applications
| Automotive Sensor Biasing | Microcontroller Reset Reference |
|---|---|
Use Scenario: Providing stable 2.7 V reference to analog front-end of engine coolant temperature sensor circuit. IC Role / Device Role / Timing Role: Zener diode acts as precision shunt regulator, maintaining constant bias voltage despite battery voltage fluctuations (9–16 V). Use Value: Enables <1 % measurement error over −40 °C to +125 °C ambient due to tight tolerance and AEC-Q101 thermal stability. |
Use Scenario: Generating reset threshold for 3.3 V microcontroller in ADAS domain controller. IC Role / Device Role / Timing Role: Functions as voltage monitor in discrete reset circuit, triggering POR when supply drops below 2.7 V. Use Value: Guarantees deterministic reset assertion with ≤20 μA leakage, minimizing false triggers during brown-out conditions. |
| USB-C Power Negotiation Clamp | Industrial I/O Protection |
Use Scenario: Clamping CC line voltage in USB-C port to prevent overvoltage damage during plug insertion. IC Role / Device Role / Timing Role: Shunt protector limiting CC pin to 2.7 V during hot-plug transients. Use Value: Responds within nanoseconds with ≤0.9 V forward drop, protecting Type-C controller GPIO without adding series resistance. |
Use Scenario: Protecting 24 V PLC analog input channel against induced surges on field wiring. IC Role / Device Role / Timing Role: Front-end Zener clamp absorbing transient energy before signal conditioning op-amp. Use Value: Handles 365 mW peak dissipation without thermal runaway, sustaining repeated 100 V/1 ms transients per IEC 61000-4-5 Level 3. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B2V7-Q | Same electrical specs and package; differs only in marking code (2B vs QYL) - QYL denotes specific tape-and-reel packaging variant per Nexperia internal coding | No functional difference; identical use in all circuits requiring 2.7 V ±2 % Zener regulation | Select QYL for traceability in automotive production lots requiring full MSL3 and lot-code tracking |
| MMSZ4678T1G | 2.7 V ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, Rth(j-a) = 300 K/W - looser tolerance but higher power rating and larger footprint | Suitable for non-automotive industrial designs where board space is less constrained and ±5 % regulation suffices | Choose only if higher power headroom is needed and AEC-Q101 qualification is not required |
Compared with BZX884S-B2V7-QYL, the Q variant offers identical regulation performance with alternate packaging logistics, while MMSZ4678T1G trades tighter tolerance and automotive qualification for higher power and larger size-making it suitable only where space and qualification requirements differ.

FAQ
What is the maximum reverse current at 1 V for BZX884S-B2V7-QYL?
The maximum reverse current (IR) is 20 μA at VR = 1 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage ensures minimal loading on bias networks and supports accurate low-current sensing applications.
Is BZX884S-B2V7-QYL compatible with lead-free reflow profiles?
Yes-it is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. The DFN1006BD-2 package uses matte tin plating and side-wettable flanks optimized for IPC-A-610 Class 2/3 solder joint formation.
Does the marking '2B' correspond to BZX884S-B2V7-QYL?
Yes-the marking code '2B' is the top-side laser mark for BZX884S-B2V7-QYL, as confirmed in Table 4 of the datasheet. The 'QYL' suffix indicates a specific tape-and-reel packaging configuration with enhanced traceability for automotive production.
Can BZX884S-B2V7-QYL be used in place of a 2.7 V TL431-based shunt regulator?
No-it is a two-terminal Zener diode, not a three-terminal adjustable shunt regulator. It lacks the internal reference and op-amp feedback of TL431, so it cannot replicate programmable threshold or high-accuracy closed-loop regulation; use only for fixed-voltage clamping or basic biasing.
