Product details
Overview
BZX884-C3V0,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 3.0 V nominal regulation at 5 mA, with 250 mW total power dissipation and 425 Ω typical differential resistance at 1 mA. It serves as a precision voltage reference or low-power shunt regulator in compact DC bias and protection circuits.
For engineers reviewing the BZX884-C3V0,315 datasheet, BZX884-C3V0,315 pinout, BZX884-C3V0,315 application, or BZX884-C3V0,315 equivalent, this page delivers verified electrical specs, thermal behavior, AEC-Q101 qualification status, and surface-mount layout guidance for high-frequency ESD clamping and stable voltage referencing in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 3.0 V reference across load variations, with temperature coefficient of −1.6 mV/K at 5 mA ensuring predictable drift over −55 °C to +150 °C ambient. Its ultra-low 0.9 V forward voltage at 10 mA supports bidirectional transient suppression when used with series resistors.
The SOD882 package enables high-density PCB placement with 1.0 mm × 0.6 mm footprint and 0.5 mm height, while its 500 K/W junction-to-ambient thermal resistance requires careful copper area planning on FR4 boards to sustain full 250 mW dissipation at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.0 V at IZ = 5 mA - defines regulated output level under standard test current |
| Zener Tolerance | ±5 % - yields 2.85 V to 3.15 V range at 5 mA, suitable for non-critical biasing |
| Differential Resistance | 325–500 Ω at IZ = 1 mA - determines regulation stiffness against current variation |
| Temperature Coefficient | −1.6 mV/K at 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation | 250 mW at Tamb ≤ 25 °C on FR4 - sets maximum continuous DC or pulsed power handling |
| Reverse Current @ 1 V | 10 µA - specifies leakage level below breakdown, critical for low-power standby circuits |
| Forward Voltage | 0.9 V at IF = 10 mA - enables use as low-drop rectifier or ESD path in bidirectional clamps |
| Junction Temperature Limit | 150 °C - constrains thermal design margin when operating near Ptot limit |

| 250 mW power rating | Permits direct shunt regulation of low-current analog rails (e.g., op-amp bias, ADC reference) |
| High-frequency ESD response | Sub-nanosecond turn-on enables clamping of fast transients up to 6 A peak (100 µs pulse) |
Applications
| Power Supply Biasing | ESD Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.0 V, ±5 %, SOT-323 package (2.1 mm × 1.3 mm), 200 mW Ptot, 170 Ω rdiff | Larger footprint and lower power; better regulation stiffness but less space-efficient | Choose when board area allows larger package and tighter regulation is prioritized over size |
| BZX384-C3V0 | 3.0 V, ±5 %, SOD-323 package (1.7 mm × 1.3 mm), 300 mW Ptot, 300 Ω rdiff | Higher power rating and larger body; not AEC-Q101 qualified | Prefer for industrial non-automotive applications requiring >250 mW headroom |
Compared with MMBZ5226BS-7-F and BZX384-C3V0, the BZX884-C3V0,315 offers the smallest PCB footprint and automotive qualification at the cost of higher dynamic impedance-making it optimal for space-limited AEC-Q101 designs where 425 Ω rdiff suffices.

FAQ
What is the maximum reverse current at 1 V for BZX884-C3V0,315?
The maximum reverse current at VR = 1 V is 10 µA, measured at Tj = 25 °C. This low leakage ensures minimal parasitic loading on high-impedance bias networks and preserves battery life in always-on sensor circuits.
Can BZX884-C3V0,315 be used in bidirectional ESD protection?
Yes-its 0.9 V forward voltage at 10 mA and 3.0 V reverse breakdown enable symmetrical clamping when paired with a series resistor. The device responds within nanoseconds to IEC 61000-4-2 transients, making it suitable for USB, I²C, and GPIO line protection.
Is thermal derating required above 25 °C ambient?
Yes-Ptot decreases linearly above 25 °C ambient at 2.5 mW/°C due to 500 K/W Rth(j-a). At 85 °C ambient, maximum allowable power drops to 100 mW. Board-level copper area must be optimized per Nexperia's SOD882 reflow footprint guidelines.
How does the −1.6 mV/K temperature coefficient affect regulation accuracy?
Over a 100 °C junction temperature swing (25 °C to 125 °C), the Zener voltage shifts by −160 mV, resulting in ±5.3 % deviation from nominal 3.0 V. For applications needing tighter stability, pairing with a temperature-compensated reference or using feedback regulation is recommended.
