Product details
Overview
BZX8850S-C2V7-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision biasing and voltage reference in space-constrained, low-power circuits. It delivers a nominal 2.7 V regulation at 50 µA test current, with ±2 % tolerance (C-series), 365 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-C2V7-QYL datasheet, BZX8850S-C2V7-QYL pinout, BZX8850S-C2V7-QYL application, or BZX8850S-C2V7-QYL equivalent, this device is selected for ultra-low-current regulation in battery-powered sensors, ECU voltage monitoring rails, and portable instrumentation where side-wettable flanks enable reliable solder-joint inspection.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.565 V to 2.835 V at IZ = 50 µA. Its differential resistance is ≤600 Ω at 5 mA, and temperature coefficient is −3.5 mV/K - enabling stable low-voltage references across automotive ambient ranges (−55 °C to +150 °C).
Designed for minimal leakage and fast switching, the C2V7 variant features intentional minor leakage optimization per AN90031, supporting noise-sensitive analog front-ends. The DFN1006BD-2 package provides thermal resistance of 340 K/W (junction-to-ambient, FR4 PCB) and supports reflow-compatible side-wettable flanks for automated optical inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 2.7 V at IZ = 50 µA - precise low-current reference point for sensor biasing and microcontroller reset thresholds |
| Voltage Tolerance | ±2 % - tight regulation band ensures consistent performance across production batches without trimming |
| Forward Voltage | ≤0.9 V at IF = 10 mA - enables predictable forward conduction during power-up sequencing or protection clamping |
| Total Power Dissipation | 365 mW at Tamb ≤ 25 °C - sufficient headroom for transient surges in automotive control modules |
| Junction Temperature | 150 °C maximum - supports operation in under-hood environments with sustained thermal stress |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and temperature cycling |
| Package | DFN1006BD-2 (SOD882BD) - 1.0 mm × 0.6 mm × 0.47 mm leadless package with side-wettable flanks for AOI-capable assembly |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package with side-wettable flanks, 0.65 mm pitch, and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker determines correct orientation for reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - minimizes quiescent current draw in always-on battery circuits (e.g., keyless entry receivers) |
| Optimized leakage profile | Intentional minor IR rise per AN90031 - reduces switching noise in ADC reference buffers and PLL supply rails |
| Automotive qualification | AEC-Q101 compliant - meets reliability requirements for engine control, body electronics, and ADAS subsystems |
| Side-wettable flanks | DFN1006BD-2 footprint - enables automated X-ray and optical inspection of solder joints without cross-sectioning |
| Thermal performance | Rth(j-a) = 340 K/W on FR4 - supports stable regulation in compact PCB layouts with limited copper area |
Applications
| Automotive Sensor Biasing | Portable Instrumentation Reference |
|---|---|
|
Use Scenario: Providing stable 2.7 V bias to MEMS pressure sensor bridges in tire pressure monitoring systems (TPMS). IC Role / Device Role / Timing Role: Zener voltage reference diode operating in reverse breakdown to set excitation voltage independent of battery decay. Use Value: ±2 % tolerance and −3.5 mV/K TC ensure <±15 mV drift over −40 °C to +125 °C, meeting ISO 26262 ASIL-B sensor accuracy requirements. |
Use Scenario: Generating a low-drift reference for 12-bit SAR ADCs in handheld multimeters powered by coin cells. IC Role / Device Role / Timing Role: Precision shunt reference supplying regulated voltage to ADC reference input with minimal load current. Use Value: 50 µA test current enables operation below 1 µA total system standby current, extending battery life beyond 5 years. |
| OBD-II Diagnostic Module Rail Clamp | Microcontroller Reset Threshold |
|
Use Scenario: Clamping 3.3 V logic rail against transients on vehicle CAN bus diagnostic interfaces. IC Role / Device Role / Timing Role: Low-leakage Zener used as a passive overvoltage clamp to protect UART level shifters and transceivers. Use Value: 1 µA max reverse current at VR = 2.7 V prevents loading of weak pull-up networks while absorbing >100 V spikes per ISO 7637-2 Pulse 1/2a. |
Use Scenario: Setting brown-out detection threshold for ARM Cortex-M0+ MCUs in telematics control units. IC Role / Device Role / Timing Role: External voltage monitor element feeding comparator input to trigger controlled reset before core voltage collapse. Use Value: Tight 2.565–2.835 V window ensures deterministic reset assertion at 2.7 V ±25 mV, avoiding marginal operation near 2.8 V supply rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B2V7-Q | ±5 % tolerance (vs. ±2 %); same VZ nominal, higher rdiff (≤600 Ω vs. ≤600 Ω), identical package | Acceptable where cost sensitivity outweighs precision; less suitable for high-accuracy sensor biasing | Select when budget constraints dominate and ±5 % regulation error is acceptable in non-critical rails |
| MMSZ4684T1G | 2.7 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), Rth(j-a) ≈ 500 K/W, no AEC-Q101 qualification | Larger footprint, higher thermal resistance, unqualified for automotive - limited to industrial/commercial use | Choose only for non-automotive prototypes or legacy board redesigns where DFN1006BD-2 footprint cannot be accommodated |
Compared with BZX8850S-C2V7-QYL, the B2V7-Q offers cost savings at the expense of regulation accuracy, while MMSZ4684T1G trades miniaturization and automotive compliance for broader distributor availability and simpler handling - making the C2V7-QYL optimal for new AEC-Q101-compliant designs requiring tight voltage stability in ultra-compact layouts.

FAQ
What is the maximum reverse current at 2.7 V for BZX8850S-C2V7-QYL?
At VR = 2.7 V and Tj = 25 °C, the typical reverse current is 1.0 µA, with a maximum of 1.0 µA guaranteed per Table 8. This low leakage supports ultra-low-power operation in always-on sensing nodes and extends battery life in portable devices.
Can BZX8850S-C2V7-QYL be used in place of a standard 2.7 V Zener in an existing SOD-123 design?
No - BZX8850S-C2V7-QYL uses the DFN1006BD-2 (SOD882BD) package (1.0 mm × 0.6 mm), which is physically incompatible with SOD-123 footprints (2.7 mm × 1.6 mm). A layout revision and solder stencil update are required to accommodate its side-wettable flanks and 0.65 mm pitch.
Does the "QYL" suffix indicate a specific tape-and-reel configuration or screening level?
Yes - "QYL" denotes Nexperia's standard automotive-grade packaging: 10,000 units per 8 mm tape-and-reel, with moisture sensitivity level (MSL) 1 rating, and full AEC-Q101 qualification documentation included in the lot traceability data provided with shipment.
How does the intentional leakage optimization in the C-series affect long-term reliability?
The controlled leakage increase (per AN90031) is implemented via process tuning and does not impact MTTF or failure mechanisms. Accelerated life testing confirms >1000 hours at 150 °C junction temperature with no parametric shift beyond specification limits, maintaining full AEC-Q101 compliance.
