Product details
Overview
BZX884-C39,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 39 V nominal regulation at 5 mA, with 250 mW total power dissipation and 40 Ω typical differential resistance at IZ = 2 mA. It delivers stable voltage reference and overvoltage clamping in compact high-density PCB layouts.
For engineers reviewing the BZX884-C39,315 datasheet, BZX884-C39,315 pinout, BZX884-C39,315 application, or BZX884-C39,315 equivalent, this page provides verified Zener voltage, thermal resistance, reverse leakage, capacitance, and AEC-Q101 qualification status - all confirmed from Nexperia's Rev. 5 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 39 V reference under regulated current conditions. Its 40 Ω typical differential resistance at 2 mA ensures low dynamic impedance for precise voltage stabilization across load variations.
With 45 pF junction capacitance at 0 V and 1 MHz, it supports high-frequency ESD suppression and fast transient response. The −55 °C to +150 °C ambient operating range and AEC-Q101 qualification confirm suitability for automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 39 V nominal at IZ = 2 mA; ±5 % tolerance ensures predictable clamping threshold in protection circuits. |
| Differential Resistance (rdiff) | 40 Ω typical at IZ = 2 mA; low impedance maintains regulation accuracy under varying current loads. |
| Junction Capacitance (Cd) | 45 pF at f = 1 MHz, VR = 0 V; enables effective high-frequency noise filtering and ESD pulse shaping. |
| Reverse Leakage (IR) | 50 nA max at VR = 27.3 V (0.7 × VZnom); minimal standby current preserves system efficiency. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB; defines maximum continuous thermal load in surface-mount layout. |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air; determines junction temperature rise under steady-state power, critical for reliability margining. |
| Non-repetitive Peak Current (IZSM) | 0.7 A at tp = 100 µs; supports single-event ESD surge handling per IEC 61000-4-2 Level 4. |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, tin-plated terminals, marking bar indicating cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar for automated assembly verification. |
| 2 (A) | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JESD22 standards. |
| Ultra-small SOD882 footprint | 1.0 × 0.6 mm area saves >60 % board space vs. SOD-123, enabling dense routing in portable and ADAS modules. |
| Low 45 pF junction capacitance | Minimizes signal distortion in RF bias networks and preserves bandwidth in high-speed data line protection. |
| 250 mW power rating with FR4 mounting | Supports sustained clamping in 12 V/24 V automotive supply rails without heatsinking or derating below 70 °C ambient. |
| ±5 % Zener tolerance | Provides cost-optimized voltage accuracy for non-critical regulation where tighter tolerance is unnecessary. |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B39,315 | ±2 % Zener tolerance (vs. ±5 %), 30 Ω rdiff typical at 2 mA, same SOD882 package and 39 V nominal rating. | Higher precision required in feedback loops for switching regulators or analog-to-digital reference buffers. | Select when tighter voltage accuracy and lower dynamic impedance outweigh cost sensitivity. |
| MMSZ5242B-7-F | 39 V nominal, ±5 %, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, 70 Ω rdiff at 20 mA. | Higher power handling needed for legacy through-hole or larger footprint designs; not AEC-Q101 qualified. | Choose only if board rework prohibits SOD882 adoption or if >250 mW continuous dissipation is mandatory. |
Compared with BZX884-B39,315, the C39 variant trades tighter tolerance for lower unit cost and identical thermal performance; versus MMSZ5242B-7-F, it offers 55 % smaller footprint, AEC-Q101 compliance, and superior high-frequency response - critical for modern automotive and portable electronics.

FAQ
What is the maximum reverse current at 39 V before breakdown?
The BZX884-C39,315 does not conduct significantly until reaching its specified Zener voltage. At VR = 27.3 V (0.7 × 39 V), reverse leakage is guaranteed ≤50 nA. Measurable conduction begins near 37 V and reaches 2 mA at 39 V, per the electrical characteristics table.
Can this diode be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficient and mismatched breakdown voltages, causing current hogging and thermal runaway when paralleled. For >250 mW operation, use a single higher-rated device or external series resistor with forced-air cooling.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD882 footprint in Figure 12 supports JEDEC J-STD-020-compliant profiles, with peak temperatures up to 260 °C and 60-second duration above 217 °C, provided copper land geometry matches the 0.9 mm × 0.3 mm pad dimensions.
How does temperature affect the 39 V Zener voltage?
At IZ = 2 mA, the temperature coefficient is +36.4 mV/K (typical). This means VZ increases by ~36 mV per °C rise in junction temperature - a +10 °C shift raises regulation to ~39.36 V, critical for precision reference designs operating beyond 25 °C ambient.
