Product details
Overview
BZX8850S-C62-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 6.2 V Zener voltage at 50 µA test current, with ±2 % tolerance (C-series), 365 mW total power dissipation, and ultra-small DFN1006BD-2 (SOD882BD) package - ideal for battery-powered wearables and automotive sensor signal conditioning.
For engineers reviewing the BZX8850S-C62-QYL datasheet, BZX8850S-C62-QYL pinout, BZX8850S-C62-QYL application, or BZX8850S-C62-QYL equivalent, this page provides verified electrical characteristics, AEC-Q101 qualification status, thermal resistance (340 K/W), side-wettable flank soldering compatibility, and direct replacement guidance for automotive-grade low-current regulation.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 6.2 V at IZ = 50 µA, exhibiting low differential resistance (≤160 Ω at IZ = 5 mA) and a positive temperature coefficient of +0.4 mV/K. Its design targets stable biasing under minimal current draw, avoiding thermal drift in portable systems.
The device uses a planar silicon process qualified to AEC-Q101, enabling operation from −55 °C to +150 °C ambient. Its DFN1006BD-2 package features side-wettable flanks for automated optical inspection (AOI) of solder joints - critical for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal at IZ = 50 µA; tight ±2 % tolerance ensures accurate reference in low-bias analog circuits. |
| Differential Resistance (rdiff) | ≤160 Ω at IZ = 5 mA; low impedance maintains regulation stability under small load variations. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA; enables use as clamping diode in bidirectional protection schemes. |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C on FR4 PCB; defines maximum continuous DC or pulsed power handling in compact layouts. |
| Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 340 K/W; quantifies self-heating under rated load - critical for derating in sealed enclosures or high-temperature environments. |
| Reverse Current (IR) | ≤1.0 µA at VR = 5.0 V; ultra-low leakage preserves battery life in always-on monitoring nodes. |
| Package | DFN1006BD-2 (SOD882BD); 1.0 mm × 0.6 mm × 0.47 mm body with side-wettable flanks for reliable reflow solder joint inspection. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package with cathode marked by a bar on the top surface. Its side-wettable flanks support automated optical inspection (AOI) of solder fillets during high-volume automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity marking (bar) enables unambiguous orientation during placement. |
| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-biased configuration establishes Zener breakdown voltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including engine control modules and ADAS sensor interfaces - supports extended temperature and reliability requirements. |
| Low test current (50 µA) | Enables stable regulation in micro-power systems (e.g., coin-cell IoT sensors) without loading sensitive bias networks. |
| Side-wettable flanks (SWF) | Facilitates AOI-compatible solder joint verification - eliminates X-ray inspection cost in Tier-1 automotive manufacturing. |
| Two tolerance options | ±2 % (C-series) and ±5 % (B-series) allow cost/performance trade-offs across consumer, industrial, and automotive designs. |
| Optimized leakage profile | Intentional minor rise in leakage current improves switching speed and reduces noise in feedback paths of LDOs and comparators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B6V2-Q | Same package and 6.2 V nominal voltage, but ±5 % tolerance (B-series) vs. ±2 % (C-series). | Suitable where tighter regulation is not required - e.g., non-critical power rail supervision. | Select when cost sensitivity outweighs precision needs; identical footprint and thermal behavior. |
| MMSZ4687T1G | 6.2 V Zener, SOD-123 package (2.7 mm × 1.6 mm), ±5 % tolerance, 500 mW Ptot, no AEC-Q101 rating. | Applicable in commercial-grade power supplies but not automotive due to larger size and lack of qualification. | Choose only for non-automotive, higher-power applications where board space permits larger package. |
Compared with BZX8850S-C62-QYL, the BZX8850S-B6V2-Q offers identical form factor and voltage but relaxed tolerance for cost-driven designs, while MMSZ4687T1G trades AEC-Q101 compliance and miniaturization for higher power handling and broader commercial availability - making it unsuitable for space- or reliability-constrained automotive use.

FAQ
What is the Zener voltage tolerance for BZX8850S-C62-QYL?
The "C" in the part number denotes ±2 % tolerance at IZ = 50 µA. This is confirmed in Table 8 of the datasheet, where BZX8850S-C6V2-Q shows VZ min = 5.89 V and max = 6.51 V - a 6.2 V nominal value with ±2 % deviation. The tighter tolerance supports precision analog biasing in automotive and medical applications.
Does BZX8850S-C62-QYL support automated optical inspection (AOI)?
Yes - its DFN1006BD-2 (SOD882BD) package features side-wettable flanks, explicitly defined in Section 6 and Figure 9 of the datasheet. This geometry allows standard AOI systems to inspect solder joint quality on both lateral edges, eliminating the need for X-ray in automotive PCB assembly per IPC-A-610 Class 3 requirements.
Can BZX8850S-C62-QYL be used in place of a standard 1N4735A?
No - while both regulate at ~6.2 V, the BZX8850S-C62-QYL is a low-current (50 µA test), ultra-miniature (1.0 mm × 0.6 mm), AEC-Q101-qualified device, whereas the 1N4735A is a through-hole, 1 W, ±5 % part in DO-41. They differ in power rating, package, test current, qualification, and thermal performance - direct substitution is not electrically or mechanically viable.
What is the maximum reverse current at 5.0 V for BZX8850S-C62-QYL?
Per Figure 5 and Table 8, the maximum reverse current (IR) is 1.0 µA at VR = 5.0 V and Tj = 25 °C. This ultra-low leakage is critical for battery-powered applications, ensuring minimal quiescent current drain in always-on monitoring circuits such as smoke detector MCU supervisors.
