Product details
Overview
BZX884-C30,315 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 30 V nominal Zener voltage at 5 mA test current, 250 mW total power dissipation, and 70 Ω typical differential resistance. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX884-C30,315 datasheet, BZX884-C30,315 pinout, BZX884-C30,315 application, or BZX884-C30,315 equivalent, this page delivers verified electrical parameters, thermal behavior under FR4 mounting, AEC-Q101 qualification status, and real-world ESD protection use cases - all extracted directly from Nexperia's Rev. 5 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown with a temperature coefficient of +26.6 mV/K at IZ = 2 mA, enabling stable voltage regulation across −55 °C to +150 °C ambient range. Its 50 pF capacitance at 1 MHz and 0.9 V forward voltage at 10 mA support high-frequency transient suppression and low-loss biasing.
The device complies with AEC-Q101 for automotive-grade reliability and features ultra-small 1.0 × 0.6 × 0.5 mm body dimensions. Its non-repetitive peak reverse current is 1.0 A for 100 µs pulses, making it suitable for ESD pulse clamping per IEC 61000-4-2 Level 4.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 30 V nominal at IZ = 2 mA; ±5% tolerance ensures predictable clamping threshold in supply rail monitoring |
| Differential Resistance (rdiff) | 70 Ω typical at IZ = 2 mA; defines voltage regulation stiffness under load variation |
| Power Dissipation (Ptot) | 250 mW maximum at Tamb ≤ 25 °C on FR4 PCB; sets continuous DC or low-duty-cycle pulse handling limit |

FAQ
What is the maximum reverse voltage the BZX884-C30,315 can withstand before breakdown?
The BZX884-C30,315 has a nominal Zener voltage of 30 V at 2 mA test current, with a guaranteed minimum of 28.5 V and maximum of 31.5 V under ±5% tolerance. Breakdown begins near the lower limit and stabilizes across the specified range; operation above 31.5 V risks exceeding absolute maximum ratings.
Is the BZX884-C30,315 suitable for high-frequency ESD protection?
Yes - its 50 pF junction capacitance at 1 MHz and 1.0 A non-repetitive peak reverse current at 100 µs enable effective clamping of fast ESD transients up to 8 kV contact discharge without distorting signal integrity on data lines like USB or I²C.
How does ambient temperature affect the Zener voltage of this diode?
At IZ = 2 mA, the BZX884-C30,315 exhibits a +26.6 mV/K temperature coefficient, meaning its Zener voltage increases by approximately 26.6 mV per degree Celsius rise in junction temperature - critical for designs operating across −40 °C to +125 °C automotive ranges.
Can this Zener diode be used in series with other components for higher-voltage regulation?
No - the BZX884-C30,315 is a single-junction device rated for 30 V operation. Cascading multiple units introduces mismatched temperature coefficients and uneven voltage sharing; for >30 V regulation, use purpose-built high-voltage Zeners or active regulation circuits.
