Product details
Overview
BZX884-C27,315 from Nexperia is a ±5 % tolerance Zener diode optimized for voltage regulation and ESD protection in ultra-compact SOD882 (DFN1006-2) packages. It delivers 27 V nominal Zener voltage at 2 mA test current, 250 mW total power dissipation, and 50 Ω typical differential resistance - enabling stable reference generation in space-constrained power rails and I/O protection circuits.
For engineers reviewing the BZX884-C27,315 datasheet, BZX884-C27,315 pinout, BZX884-C27,315 application, or BZX884-C27,315 equivalent, this page provides verified package dimensions, thermal resistance (500 K/W), reverse leakage (<100 nA at 18.9 V), temperature coefficient (+23.4 mV/K), and AEC-Q101 qualification status - all critical for automotive and industrial board-level design validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage across its terminals under varying load and temperature conditions. Its 27 V nominal Zener voltage is specified at 2 mA test current with ±5 % tolerance, and exhibits a positive temperature coefficient of +23.4 mV/K - indicating voltage increases linearly with junction temperature rise.
The device uses planar epitaxial construction in a leadless DFN1006-2 package, supporting high-frequency response (capacitance ≤50 pF at 1 MHz, VR = 0 V) and ultra-fast ESD clamping (non-repetitive peak reverse current up to 1.0 A for 100 µs pulses). It is qualified to AEC-Q101 for automotive use and rated for 150 °C maximum junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B27,315 | ±2 % tolerance (vs. ±5 %); tighter 26.46–27.57 V range; higher rdiff (65 Ω vs. 300 Ω max at 0.5 mA) | Preferred where absolute voltage accuracy dominates over dynamic impedance in feedback loops | Select for closed-loop regulator references requiring <±0.5 % error budget |
| MMSZ5254ET1G | Same 27 V nominal rating but SOD-123 package (2.7 × 1.6 mm); 500 mW Ptot; ±5 %; rdiff = 40 Ω typ | Higher power handling suits higher-current bias networks but occupies 7× more PCB area | Choose when thermal margin >250 mW is required and layout space permits larger footprint |
Compared with BZX884-C27,315, the BZX884-B27,315 offers superior voltage precision at the cost of higher dynamic impedance, while MMSZ5254ET1G trades miniaturization for greater power derating headroom - making the C-series optimal for space-constrained, low-leakage, AEC-Q101-compliant designs.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX884-C27,315 has a nominal Zener voltage of 27 V at 2 mA test current, with guaranteed breakdown occurring between 25.65 V and 28.35 V (±5 % tolerance). Its absolute maximum non-repetitive peak reverse voltage is not specified; instead, it is rated for 1.0 A surge current at 100 µs pulse width - implying safe operation up to ~30 V in transient clamping scenarios.
Is this diode suitable for use in a 24 V automotive power rail?
Yes - the BZX884-C27,315 is AEC-Q101 qualified and designed for automotive environments. With a 27 V nominal Zener voltage, it provides appropriate overvoltage clamping headroom above nominal 24 V systems (including load dump peaks up to 35 V), while its 250 mW power rating supports continuous regulation in low-current bias networks.
How does the SOD882 package affect thermal performance?
The SOD882 package has a junction-to-ambient thermal resistance of 500 K/W under standard FR4 mounting conditions. This limits continuous power dissipation to 250 mW at 25 °C ambient; at 85 °C ambient, derated power drops to ~150 mW. No thermal pad is present, so PCB copper area and airflow are primary thermal management levers.
Can this Zener replace a 24 V Zener in an existing design?
No - the BZX884-C27,315 is a 27 V device and will regulate at ~27 V, not 24 V. Substituting it for a 24 V Zener would raise reference or clamp voltages by ~3 V, potentially violating downstream IC absolute maximum ratings. For 24 V replacement, select BZX884-C24,315 (24 V nominal, ±5 %).
