Product details
Overview
BZX884-B75,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 75 V nominal Zener voltage at IZ = 5 mA, 250 mW total power dissipation, and 170 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-B75,315 datasheet, BZX884-B75,315 pinout, BZX884-B75,315 application, or BZX884-B75,315 equivalent, this page delivers verified electrical specs, thermal limits, AEC-Q101 qualification status, and surface-mount footprint details required for automotive sensor interface and industrial power rail monitoring designs.
Technical Context
This Zener diode operates in reverse breakdown with a temperature coefficient of +80.2 mV/K at IZ = 5 mA, indicating positive voltage drift with junction temperature rise. Its 35 pF capacitance at 1 MHz and 0 V reverse bias supports high-frequency transient suppression up to ~100 MHz.
Rated for −55 °C to +150 °C ambient operation and 150 °C maximum junction temperature, it sustains non-repetitive peak reverse current of 0.2 A for 100 µs pulses under standard FR4 mounting conditions, enabling ESD protection in compact portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 75 V nominal at IZ = 5 mA; ±2 % tolerance ensures tight regulation in feedback loops. |
| Differential Resistance (rdiff) | 170 Ω typical at IZ = 5 mA; defines output impedance and load regulation error. |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB; sets maximum continuous clamping energy. |
| Reverse Current (IR) | 50 nA max at VR = 0.7 × VZ; guarantees low leakage in high-impedance bias networks. |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; enables predictable forward conduction during polarity reversal events. |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air; determines junction-to-ambient temperature rise under steady-state power. |
| Capacitance (Cd) | 35 pF at f = 1 MHz, VR = 0 V; limits high-frequency signal distortion in RF-coupled paths. |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, tin-plated copper terminals, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
| Ultra-small DFN1006-2 footprint | Enables placement in space-constrained modules such as battery management ICs and wearables. |
| ±2 % Zener voltage tolerance | Reduces need for post-production trimming in precision voltage reference applications. |
| Low 35 pF junction capacitance | Maintains signal integrity in >10 MHz clock line clamping and RF detector biasing. |
| 150 °C maximum junction temperature | Supports operation in under-hood automotive environments without derating below 125 °C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C75,315 | ±5 % tolerance; higher rdiff (255 Ω typ); identical package and thermal specs. | Acceptable where cost sensitivity outweighs precision requirement. | Select when ±5 % VZ tolerance suffices and budget constraints dominate. |
| MMSZ5265B-7-F | Same 75 V nominal, ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot. | Requires larger PCB area but supports higher continuous power in non-space-constrained designs. | Choose when board space permits larger footprint and higher power handling is needed. |
Compared with BZX884-C75,315, the BZX884-B75,315 offers tighter voltage control at the expense of slightly higher cost; versus MMSZ5265B-7-F, it trades 54 % smaller footprint for 50 % lower power rating-critical for miniaturized automotive modules.

FAQ
What is the maximum reverse voltage the BZX884-B75,315 can safely clamp?
The BZX884-B75,315 is rated for 75 V nominal Zener voltage at 5 mA test current, with a guaranteed minimum of 73.5 V and maximum of 76.5 V under ±2 % tolerance. Its absolute maximum reverse voltage is not specified separately-it operates within its Zener breakdown region up to its limiting power dissipation of 250 mW at 25 °C ambient.
Is the BZX884-B75,315 suitable for use in reflow soldering processes?
Yes-the SOD882 package is explicitly qualified for reflow soldering only, with a recommended footprint defined in Figure 12 of the datasheet. The device withstands JEDEC J-STD-020-compliant peak temperatures up to 260 °C for ≤ 30 seconds, matching standard lead-free reflow profiles.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +80.2 mV/K temperature coefficient at 5 mA, the BZX884-B75,315 exhibits a +0.107 %/°C drift relative to its 75 V nominal value. Over a −40 °C to +125 °C junction range, this contributes ±13.2 V shift-requiring system-level compensation if sub-1 % total regulation accuracy is required.
Can the BZX884-B75,315 replace older Zener diodes like the BZX55C75 in existing designs?
No-BZX884-B75,315 uses a 1.0 × 0.6 mm DFN1006-2 package, while BZX55C75 uses DO-35 glass axial package. Mechanical incompatibility prevents direct replacement; redesign of PCB footprint and thermal layout is required despite similar electrical ratings.
