Product details
Overview
BZX884-B10,315 from Nexperia is a 10 V ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 250 mW total power dissipation and 200 mA maximum forward current, used for precision voltage regulation and ESD protection in space-constrained PCBs.
For engineers reviewing the BZX884-B10,315 datasheet, BZX884-B10,315 pinout, BZX884-B10,315 application, or BZX884-B10,315 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance data directly tied to AEC-Q101 qualified operation in automotive and industrial environments.
Technical Context
This Zener diode operates with a nominal Zener voltage of 10 V at 5 mA test current, exhibiting a typical differential resistance of 20 Ω and a positive temperature coefficient of +6.0 mV/K - enabling stable regulation across temperature gradients in bias networks and reference circuits.
Its ultra-small DFN1006-2 footprint (1.0 × 0.6 × 0.5 mm) supports high-density layouts, while AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−55 °C to +150 °C) and transient robustness per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.80 V to 10.20 V at IZ = 5 mA - defines precise clamping threshold for 10 V reference designs |
| Differential Resistance (rdiff) | 20 Ω max at IZ = 5 mA - ensures low dynamic impedance for stable regulation under load variation |
| Temperature Coefficient (SZ) | +6.0 mV/K typical at IZ = 5 mA - quantifies voltage drift with junction temperature rise |
| Reverse Leakage (IR) | 200 nA max at VR = 7 V - guarantees minimal standby current in high-impedance bias networks |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables predictable conduction in series protection paths |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets thermal derating baseline for surface-mount layout |
| Junction-to-Ambient Rth(j-a) | 500 K/W - informs thermal design margin when mounted on standard single-sided copper |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small plastic surface-mount package measuring 1.0 mm × 0.6 mm × 0.5 mm, with exposed copper terminals and cathode marked by a bar on the top surface.
