Product details
Overview
BZX8850-C8V2YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 8.2 V nominal with ±2 % tolerance. It delivers stable reference voltage under 50 μA test current, features 80 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range-ideal for battery-powered sensor nodes and portable IoT power rails.
For engineers reviewing the BZX8850-C8V2YL datasheet, BZX8850-C8V2YL pinout, BZX8850-C8V2YL application, or BZX8850-C8V2YL equivalent, key selection criteria include its ultra-low bias current capability, tight 8.2 V Zener voltage tolerance, thermal resistance of 500 K/W on FR4 PCB, and intentional leakage optimization for noise-sensitive analog front-ends.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 8.2 V at IZ = 50 μA, exhibiting a temperature coefficient of +3.2 mV/K and differential resistance of 80 Ω at 5 mA. Its design targets low-power regulation where minimal quiescent current and predictable thermal drift are critical.
The device uses a planar silicon junction structure optimized for fast transient response and reduced noise, with intentional minor leakage current per AN90031 to improve switching behavior in feedback loops. It is rated for 250 mW total power dissipation on standard FR4 PCB and supports non-repetitive surge up to 40 W for 100 μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.79 V to 8.61 V at IZ = 50 μA - ensures precise 8.2 V reference under ultra-low bias conditions |
| Differential Resistance rdiff | 80 Ω at IZ = 5 mA - maintains voltage stability against load current variation in feedback networks |
| Temperature Coefficient SZ | +3.2 mV/K - enables predictable voltage drift compensation in temperature-varying environments |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - allows use as low-drop rectifier or clamp in dual-role circuits |
| Reverse Current IR | ≤ 0.1 μA at VR = 6.2 V - minimizes standby power loss in always-on regulation paths |
| Package Thermal Resistance Rth(j-a) | 500 K/W on single-sided FR4 - defines maximum power handling before junction exceeds 150 °C |
| Capacitance Cd | 150 pF at VR = 0 V, f = 1 MHz - limits high-frequency noise coupling in signal-path references |

Applications
| Portable Sensor Reference | Low-Power MCU Reset Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2 | Same 8.2 V, ±2 %, but SOT-23 package (2.9 × 1.3 × 1.0 mm); 350 mW Ptot; rdiff = 40 Ω at 5 mA | Higher power handling and lower impedance, but 3× larger footprint and higher thermal mass | Select when board space permits and lower dynamic impedance is prioritized over size or ultra-low bias current |
| MMSZ5236B | 8.2 V, ±5 %, SOD-123 package; 500 mW Ptot; rdiff = 30 Ω at 20 mA; no intentional leakage optimization | Higher power rating and tighter rdiff, but looser tolerance and no AN90031 noise-reduction tuning | Select for cost-sensitive industrial controls where ±5 % tolerance is acceptable and surge immunity >40 W is required |
Compared with BZX8850-C8V2YL, BZX84-C8V2 offers superior dynamic regulation but sacrifices miniaturization and low-current precision, while MMSZ5236B trades tolerance and noise performance for ruggedness and cost-making BZX8850-C8V2YL optimal for space-constrained, battery-critical designs demanding tight voltage accuracy at microamp bias.

FAQ
What is the maximum continuous power dissipation for BZX8850-C8V2YL on a standard PCB?
The device is rated for 250 mW total power dissipation when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard footprint per datasheet condition [2]. Exceeding this value risks junction temperature exceeding 150 °C, triggering permanent degradation. Derating is required above 25 °C ambient per the 500 K/W thermal resistance specification.
How does the "intentional minor rise of leakage current" benefit circuit performance?
Per Application Note AN90031, this controlled leakage improves transient response and reduces switching noise in feedback loops by minimizing minority-carrier storage effects. It enables faster recovery after overvoltage events and lowers broadband noise floor in precision reference paths-particularly valuable in sensor signal chains and low-noise LDO error amplifiers.
Can BZX8850-C8V2YL be used in bidirectional clamping configurations?
Yes-two devices mounted anode-to-anode or cathode-to-cathode form a symmetrical ±8.2 V clamp. The 150 pF capacitance at 0 V and low rdiff ensure minimal signal distortion below 10 MHz, making it suitable for audio limiting and RS-485 bus protection where balanced clamping and fast response are required.
What marking code identifies BZX8850-C8V2YL on the package?
The marking code is "0T", laser-etched on the top surface of the DFN1006-2 package. The cathode is indicated by a visible bar adjacent to pin 1, consistent with the simplified outline in Table 2 of the datasheet. This code uniquely distinguishes the C-series 8.2 V variant from B-series (6Y) and other voltage grades.
