Product details
Overview
BZX884-B6V8,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 6.66 V to 6.94 V nominal Zener voltage at IZ = 5 mA, 250 mW total power dissipation, and 30 Ω typical differential resistance - used for precision voltage regulation and ESD protection in space-constrained automotive and industrial PCBs.
For engineers reviewing the BZX884-B6V8,315 datasheet, BZX884-B6V8,315 pinout, BZX884-B6V8,315 application, or BZX884-B6V8,315 equivalent, this device supports high-frequency clamping, low-leakage reverse bias operation down to 2 nA at 4.76 V, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled voltage tolerance (±2 %), exhibiting a positive temperature coefficient of +3.0 mV/K at IZ = 5 mA and junction capacitance of 6 pF at f = 1 MHz, VR = 0 V - enabling stable reference generation across −55 °C to +150 °C ambient.
Its ultra-small DFN1006-2 footprint (1.0 × 0.6 × 0.5 mm) and leadless construction support high-density routing, while the 200 mA maximum forward current and 6 A non-repetitive peak reverse surge capability (tp = 100 µs) allow robust transient suppression in compact power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.66 V to 6.94 V at IZ = 5 mA - defines precise regulation threshold for 6.8 V nominal rail stabilization |
| Tolerance | ±2 % - ensures tight voltage matching across production batches without post-assembly trimming |
| Differential Resistance (rdiff) | 30 Ω typical at IZ = 5 mA - minimizes output voltage shift under load variation in feedback networks |
| Reverse Leakage (IR) | 2 µA max at VR = 4 V - enables low-power standby mode integrity in battery-backed circuits |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets thermal derating boundary for continuous DC regulation |
| Junction-to-Ambient Rth | 500 K/W - determines required copper area and airflow for thermal management in sealed enclosures |
| Capacitance (Cd) | 6 pF at 1 MHz, VR = 0 V - preserves signal integrity in >100 MHz ESD clamp paths without resonance |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, with exposed cathode marking bar visible on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use up to 150 °C junction temperature and 1000-cycle thermal shock |
| Ultra-small DFN1006-2 | Reduces PCB area by 70 % vs. SOD-323, enabling placement adjacent to IC pins for localized ESD protection |
| Low dynamic impedance | 30 Ω typical rdiff maintains <±10 mV regulation error over 1–10 mA load current swing |
| High surge robustness | 6 A non-repetitive peak reverse current (tp = 100 µs) withstands IEC 61000-4-2 Level 4 contact discharge |
| Low leakage at low VR | 2 µA max at 4 V reverse bias ensures minimal quiescent current drain in always-on sensor interfaces |

FAQ
What is the maximum steady-state power dissipation for BZX884-B6V8,315?
The BZX884-B6V8,315 has a maximum total power dissipation of 250 mW at ambient temperatures ≤25 °C on an FR4 PCB with standard single-sided copper footprint. Derating is required above 25 °C at 2.0 mW/°C based on its 500 K/W junction-to-ambient thermal resistance.
How is polarity identified on the SOD882 package?
Polarity is marked by a visible bar on the top surface of the SOD882 package, aligned with Pin 1 (cathode). The unmarked side corresponds to Pin 2 (anode). This marking is confirmed in Figure 11 of the official Nexperia datasheet Rev. 5.
Does BZX884-B6V8,315 support bidirectional ESD protection?
No - BZX884-B6V8,315 is a unidirectional Zener diode optimized for reverse-bias regulation and clamping. For bidirectional ESD protection, a dedicated TVS diode such as PESD5V0S1BA should be used instead.
What is the typical Zener impedance at 1 mA test current?
At IZ = 1 mA, the typical differential resistance is 80 Ω for the BZX884-B6V8,315, per Table 8 of the Nexperia datasheet. This value increases significantly below 1 mA, reaching ~400 Ω at 0.1 mA, reflecting steeper knee characteristics at low currents.
