Product details
Overview
BZX8850S-C3V0-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision voltage reference and regulation in space-constrained, low-power circuits. It delivers a nominal 3.0 V Zener voltage at 50 µA test current, with ±2 % tolerance (C-series), 600 Ω max differential resistance at 5 mA, and 0.8 µA max reverse leakage at VR = 3.0 V - optimized for battery-powered sensor nodes and automotive microcontroller reset circuits.
For engineers reviewing the BZX8850S-C3V0-QYL datasheet, BZX8850S-C3V0-QYL pinout, BZX8850S-C3V0-QYL application, or BZX8850S-C3V0-QYL equivalent, this page provides verified package mapping (DFN1006BD-2), terminal roles (anode/cathode), thermal resistance (340 K/W), AEC-Q101 qualification status, and direct replacement options with documented electrical divergence.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.85 V to 3.15 V at IZ = 50 µA, enabling stable biasing in ultra-low-current analog front-ends. Its intentional minor leakage rise improves switching speed and reduces noise per AN90031, making it suitable for fast transient response in power-on reset (POR) and reference buffering.
The device uses a planar silicon junction structure housed in a side-wettable-flank DFN1006BD-2 package, supporting automated optical solder-joint inspection. Thermal resistance from junction to ambient is 340 K/W on FR4 PCB - a key constraint for derating in thermally isolated automotive sub-modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.85 V to 3.15 V at IZ = 50 µA - defines precise regulation threshold for 3.0 V logic supply monitoring |
| Tolerance | ±2 % (C-series) - ensures tight voltage accuracy without post-production trimming |
| Differential Resistance (rdiff) | ≤600 Ω at IZ = 5 mA - limits output impedance drift under load variation in reference paths |
| Reverse Leakage (IR) | ≤0.8 µA at VR = 3.0 V - minimizes quiescent current draw in always-on battery circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamp in dual-role designs |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C - sets maximum continuous dissipation on standard FR4 PCB |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation across full automotive temperature range |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V0,315 | Same 3.0 V ±5 % (B-series), SOT23 package (2.9 mm × 1.3 mm), 350 mW Ptot, 900 Ω rdiff | Larger footprint and higher rdiff reduce accuracy in precision references but improve surge handling | Select when board space allows larger package and cost sensitivity outweighs ±2 % tolerance requirement |
| MMSZ5226ET1G | 3.0 V ±5 %, SOD-123 package (3.7 mm × 1.6 mm), 500 mW Ptot, 17 Ω rdiff at 20 mA | Lower rdiff suits higher-current references but lacks AEC-Q101 qualification and SWF | Select for industrial non-automotive applications needing tighter dynamic regulation under variable load |
Compared with BZX8850S-C3V0-QYL, BZX84-C3V0,315 trades tolerance and size for cost and ruggedness, while MMSZ5226ET1G offers superior regulation linearity but no automotive qualification or side-wettable flanks - making the QYL variant optimal for space-limited, AEC-compliant 3.0 V reference designs.

FAQ
What is the maximum reverse voltage (VR) this diode can withstand before breakdown?
The BZX8850S-C3V0-QYL has a nominal Zener voltage of 3.0 V with a guaranteed range of 2.85 V to 3.15 V at IZ = 50 µA. Its absolute maximum reverse voltage is not defined separately - operation beyond VZ initiates controlled breakdown. The device is rated for non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses, but sustained reverse bias must remain within the specified VZ window to avoid thermal runaway.
Does this part support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Nexperia provides a dedicated footprint (Fig. 10) with 0.65 mm pitch, 0.4 mm pad width, and 1.0 mm pad length. Peak temperature must not exceed 260 °C for ≤60 seconds, and side-wettable flanks enable post-reflow optical inspection without X-ray.
How does the "C" suffix differ from "B" in the BZX8850S-Q series?
The "C" suffix denotes ±2 % Zener voltage tolerance (e.g., BZX8850S-C3V0-QYL: 2.85–3.15 V), while "B" indicates ±5 % (e.g., BZX8850S-B3V0-Q: 2.85–3.15 V for B-series is incorrect - actual B3V0 is 2.94–3.06 V). C-series parts also feature an intentional minor rise in leakage current to enhance switching speed and reduce noise, per application note AN90031.
Can this Zener diode be used in forward conduction mode?
Yes - its forward voltage is specified as ≤0.9 V at IF = 10 mA, making it usable as a low-drop clamp or level shifter. However, its primary design intent is reverse-bias Zener operation. Forward conduction should be limited to ≤200 mA (absolute maximum IF), and thermal derating applies: at 150 °C junction temperature, continuous forward current must be reduced to maintain safe operating area.
