Product details
Overview
BZX884S-B6V8-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 6.8 V breakdown voltage (±2 % tolerance), 30 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the ultra-small DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-B6V8-QYL datasheet, BZX884S-B6V8-QYL pinout, BZX884S-B6V8-QYL application, or BZX884S-B6V8-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low 4.5 pF capacitance at 0 V - critical for ESD-sensitive signal line clamping and stable biasing in sensor interfaces.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with tightly controlled VZ = 6.66–6.94 V at IZ = 5 mA, exhibiting a positive temperature coefficient of +1.2 mV/K across its operating current range. Its low differential resistance (30 Ω typ.) ensures minimal voltage shift under load variation, supporting stable regulation in low-power analog rails.
The device uses planar epitaxial construction with silicon die mounted in a leadless DFN1006BD-2 package featuring side-wettable flanks for reliable solder-joint inspection. Thermal resistance from junction to ambient is 340 K/W on standard FR4, enabling operation up to 150 °C without derating in thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.66 V to 6.94 V at IZ = 5 mA - defines precise clamping threshold for 6.8 V nominal rail protection |
| Tolerance | ±2 % - enables tight voltage margin control in automotive sensor biasing and ADC reference circuits |
| Differential Resistance (rdif) | 30 Ω typical at IZ = 5 mA - ensures <15 mV output shift per 0.5 mA load change, critical for stable feedback nodes |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - supports continuous operation in space-constrained modules without heatsinking |
| Reverse Capacitance (Cd) | 4.5 pF at f = 1 MHz, VR = 0 V - minimizes high-frequency signal distortion in RF front-end ESD protection |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - provides predictable, low-drift voltage reference over −55 °C to +150 °C |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables use as polarity-sensitive clamp in bidirectional transient suppression |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated optical inspection and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV), enabling use in ADAS sensors and body control modules |
| Side-wettable flanks | Enables automated X-ray and AOI inspection of solder joints on bottom-terminated terminals - essential for zero-defect manufacturing in automotive SMT lines |
| Low 4.5 pF capacitance | Preserves signal integrity in high-speed data lines (e.g., CAN FD, LIN, I²C) when used for ESD clamping without bandwidth degradation |
| 150 °C maximum junction temperature | Supports deployment in engine bay electronics and powertrain modules where ambient temperatures exceed 105 °C |
| 30 Ω differential resistance | Delivers <±5 mV regulation error over ±1 mA load current variation - suitable for precision voltage references in 12-bit ADC circuits |

FAQ
What is the maximum reverse current (IR) at 4 V for BZX884S-B6V8-QYL?
At 4 V reverse bias and Tj = 25 °C, the maximum reverse current is 2 μA. This low leakage ensures minimal quiescent power draw in always-on sensor bias networks and preserves battery life in low-power IoT nodes.
Can BZX884S-B6V8-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging and thermal runaway when paralleled. For >365 mW needs, use a single higher-rated device or active regulation instead.
Is the marking 'N3' on the top surface sufficient to identify BZX884S-B6V8-QYL?
Yes - per Table 4 of the datasheet, 'N3' is the unique marking code assigned exclusively to BZX884S-B6V8-QYL. The bar adjacent to pin 1 confirms cathode orientation, enabling unambiguous visual identification during manual assembly or AOI verification.
Does BZX884S-B6V8-QYL require derating above 70 °C ambient temperature?
Yes - thermal resistance is 340 K/W on standard FR4. At 100 °C ambient, maximum allowable power drops to 215 mW (calculated as (150 − 100) / 340). Derating curves are provided in Figure 9 of the datasheet for precise thermal design.
