Product details
Overview
BZX884-C7V5 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation and ESD protection at 7.5 V nominal Zener voltage with 15 Ω typical differential resistance at 5 mA, 3.6 mV/K temperature coefficient, and 170 pF capacitance at 0 V - deployed in power rail clamping and reference circuits for automotive body control modules.
For engineers reviewing the BZX884-C7V5 datasheet, BZX884-C7V5 pinout, BZX884-C7V5 application, or BZX884-C7V5 equivalent, this page delivers verified Zener voltage, thermal resistance, reverse leakage, forward voltage, and AEC-Q101 qualification status - critical for low-power, high-frequency, and automotive-grade designs requiring stable clamping under transient stress.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 7.35–7.88 V reference across 5 mA test current, with low 15 Ω dynamic impedance ensuring minimal voltage deviation under load variation. Its 3.6 mV/K positive temperature coefficient compensates for ambient drift in mid-voltage rails.
Designed for surface-mount use in ultra-compact layouts, it delivers 250 mW total power dissipation on FR4 PCB with 60 µm copper, and supports non-repetitive 4 A surge current at 100 µs pulse width - enabling robust ESD immunity per IEC 61000-4-2 Level 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35–7.88 V at IZ = 5 mA - defines precise clamping threshold for 7.5 V supply rails |
| Differential Resistance (rdiff) | 15 Ω typ. at IZ = 5 mA - ensures <±50 mV output shift under ±0.75 mA load change |
| Temperature Coefficient (SZ) | +3.6 mV/K at IZ = 5 mA - provides predictable, linear voltage rise with junction temperature |
| Reverse Leakage (IR) | 1 µA max. at VR = 5 V - guarantees low standby power loss in always-on monitoring circuits |
| Forward Voltage (VF) | 0.9 V max. at IF = 10 mA - enables efficient anode-cathode conduction during overvoltage crowbar events |
| Junction-to-Ambient Rth(j-a) | 500 K/W - sets thermal derating limit to ~125 mW at 70 °C ambient on standard FR4 |
| Capacitance (Cd) | 170 pF at f = 1 MHz, VR = 0 V - determines high-frequency filtering capability in RF bias networks |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 × 0.6 × 0.5 mm body, tin-plated terminals, marking bar indicating cathode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B7V5 | ±2% tolerance (7.35–7.65 V), lower rdiff (15 Ω vs. 15 Ω typ.), identical package and thermal specs | Preferred for high-accuracy reference circuits where 0.25 V tighter voltage window improves ADC linearity | Select when voltage precision outweighs cost sensitivity; same footprint and layout compatibility |
| MMSZ5236B-7-F | ±5% tolerance (7.14–7.86 V), higher rdiff (30 Ω), SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot | Suitable for industrial power supplies where board space allows larger package and higher power margin | Choose only if thermal headroom >250 mW is required; not drop-in due to size and pad mismatch |
Compared with BZX884-B7V5, the C7V5 trades 0.2 V voltage window tolerance for broader production yield and lower unit cost; versus MMSZ5236B-7-F, it sacrifices 250 mW power headroom for 73% smaller footprint and AEC-Q101 qualification - making it optimal for space- and reliability-constrained automotive edge nodes.

FAQ
What is the maximum reverse current before Zener breakdown for BZX884-C7V5?
At VR = 5 V, the maximum reverse leakage current is 1 µA - measured under Tj = 25 °C and specified in Table 7 of the datasheet. This low leakage ensures minimal quiescent power draw in always-on circuits such as battery-backed real-time clocks or sensor wake-up monitors.
Can BZX884-C7V5 be used in place of a 7.5 V linear regulator?
No - it functions as a shunt regulator, not a series regulator. It requires a series current-limiting resistor to set operating current and cannot source load current. It is appropriate for low-current biasing or clamping, but not for powering loads exceeding ~10 mA without external buffering.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with JEDEC J-STD-020-compliant peak temperature up to 260 °C. The footprint in Figure 12 (0.7 mm pad length, 0.3 mm pad width, 0.6 mm pitch) ensures reliable wetting and void-free joints on standard FR4 assemblies.
How does the +3.6 mV/K temperature coefficient affect circuit performance?
This positive coefficient causes the Zener voltage to increase by 3.6 mV per Kelvin rise in junction temperature. In a 7.5 V rail, a 50 °C rise yields +180 mV shift - acceptable for non-critical clamping but requires compensation (e.g., complementary NTC network) in precision references above 0.1% accuracy.
