Product details
Overview
BZX884-C47,315 from Nexperia is a ±5 % tolerance Zener diode with 47 V nominal regulation voltage, 250 mW total power dissipation, and SOD882 (DFN1006-2) ultra-small surface-mount package. It operates as a precision voltage reference or overvoltage clamp in low-power analog circuits, ESD protection paths, and high-frequency bias networks.
For engineers reviewing the BZX884-C47,315 datasheet, BZX884-C47,315 pinout, BZX884-C47,315 application, or BZX884-C47,315 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (≤170 Ω at IZ = 2 mA), temperature coefficient (+46.1 mV/K), junction-to-ambient thermal resistance (500 K/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode delivers stable reverse-biased voltage regulation at 47 V with a typical temperature coefficient of +46.1 mV/K and differential resistance of 85–170 Ω depending on test current. Its SOD882 package enables high-density PCB layouts while maintaining thermal performance under 250 mW dissipation limits.
Designed for operation across −55 °C to +150 °C ambient range, it supports non-repetitive peak reverse currents up to 0.5 A (100 µs pulse) and exhibits ≤50 nA reverse leakage at 0.7 × VZnom. The cathode-marked anode-cathode configuration ensures unambiguous polarity during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 46.06 V to 49.35 V at IZ = 2 mA - defines regulation window for precision clamping or reference use |
| Tolerance | ±5 % - specifies maximum deviation from nominal 47 V under standard test conditions |
| Differential Resistance (rdiff) | 85 Ω (typ) to 170 Ω (max) at IZtest = 2 mA - determines output impedance and regulation stiffness |
| Temperature Coefficient (SZ) | +46.1 mV/K (typ) - quantifies VZ drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC or average pulsed power handling |
| Reverse Leakage Current (IR) | ≤50 nA at VR = 32.9 V (0.7 × 47 V) - ensures minimal standby current in high-impedance bias networks |
| Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 500 K/W - defines temperature rise per watt dissipated under standard mounting conditions |

FAQ
What is the maximum reverse current the BZX884-C47,315 can handle in surge conditions?
The BZX884-C47,315 supports a non-repetitive peak reverse current (IZSM) of 0.5 A for 100 µs square-wave pulses at Tamb = 25 °C. This capability enables effective transient suppression in ESD events per IEC 61000-4-2 Level 4 (8 kV contact), provided PCB layout minimizes parasitic inductance and thermal mass is sufficient to absorb single-event energy.
How does the ±5 % tolerance affect regulation accuracy in a 47 V reference circuit?
At 47 V nominal, ±5 % tolerance means the actual Zener voltage falls between 44.65 V and 49.35 V at IZ = 2 mA. In precision reference applications, this requires system-level calibration or trimming. For clamping, the band ensures consistent overvoltage threshold behavior across production lots without post-assembly adjustment.
Can the BZX884-C47,315 be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same series, slight VZ mismatches cause current hogging. Parallel operation of BZX884-C47,315 units risks thermal runaway and premature failure; derating or using a single higher-power device is recommended instead.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes-the SOD882 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended profile uses peak temperature of 260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s and cooling rate ≥1 °C/s. Figure 12 in the datasheet provides exact solder land dimensions and stencil recommendations for void-free joints.
