Product details
Overview
BZX884-B7V5,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 7.5 V nominal regulation at 5 mA, with 250 mW total power dissipation and 1 µA reverse current at 5 V, used for precision voltage reference and ESD protection in space-constrained automotive and industrial PCBs.
For engineers reviewing the BZX884-B7V5,315 datasheet, BZX884-B7V5,315 pinout, BZX884-B7V5,315 application, or BZX884-B7V5,315 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, cathode/anode terminal mapping, 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 stable 7.5 V regulation across load and temperature variations. Its ±2 % tolerance ensures tight voltage control, while low 15–80 Ω differential resistance at IZ = 5 mA supports minimal output impedance under dynamic current conditions.
The device exhibits a +3.6 mV/K temperature coefficient at 5 mA, enabling predictable drift compensation in thermal-aware designs. Its 170 pF capacitance at 1 MHz and 0 V reverse bias makes it suitable for high-frequency decoupling and transient suppression without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - defines precise regulation window for feedback or reference circuits |
| Tolerance | ±2 % - enables tighter system-level voltage margining than ±5 % variants |
| Differential Resistance (rdiff) | 15 Ω (typ), 80 Ω (max) at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | 1 µA max at VR = 5 V - ensures low leakage in standby or high-impedance bias networks |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 - sets maximum continuous DC or pulsed power handling |
| Temperature Coefficient (SZ) | +3.6 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal design |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines anode-cathode drop during forward conduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C7V5,315 | ±5 % tolerance (7.13–7.88 V), higher 2–10 Ω rdiff, same SOD882 package | Acceptable where system-level calibration compensates wider voltage spread | Select when cost sensitivity outweighs need for tight regulation tolerance |

FAQ
What is the maximum reverse current for BZX884-B7V5,315 at 5 V?
The maximum reverse current (IR) is 1 µA at VR = 5 V and Tj = 25 °C, as specified in Table 7 of the Nexperia datasheet Rev. 5. This low leakage supports energy-efficient operation in always-on monitoring circuits and extends battery life in portable systems.
Is BZX884-B7V5,315 qualified for automotive use?
Yes - BZX884-B7V5,315 is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and human-body-model ESD (≥2 kV). Its SOD882 package and ±2 % tolerance meet requirements for under-hood and infotainment subsystems.
How does the +3.6 mV/K temperature coefficient affect circuit performance?
The +3.6 mV/K coefficient means the Zener voltage increases by 3.6 mV per degree Celsius rise in junction temperature at IZ = 5 mA. This positive drift must be factored into thermal design - for example, a 50 °C rise adds ~180 mV to VZ, impacting ADC reference accuracy unless compensated.
Can BZX884-B7V5,315 replace BZX884-C7V5,315 in existing designs?
Yes, with functional impact: BZX884-B7V5,315 provides tighter ±2 % regulation (7.35–7.65 V) versus ±5 % for the C variant (7.13–7.88 V). No layout change is needed - both share identical SOD882 footprint and pinout - but system-level voltage margins should be revalidated.
