Product details
Overview
BZX884-B3V6,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 3.6 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 375 Ω typical differential resistance at 1 mA - used for precision voltage regulation and ESD protection in space-constrained automotive and industrial PCBs.
For engineers reviewing the BZX884-B3V6,315 datasheet, BZX884-B3V6,315 pinout, BZX884-B3V6,315 application, or BZX884-B3V6,315 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low thermal resistance (500 K/W), AEC-Q101 qualification, ultra-small 1.0 × 0.6 mm footprint, and reverse leakage of 5 µA at VR = 1 V.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its ±2 % tolerance ensures tight regulation across production batches, and its AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−55 °C to +150 °C).
The device exhibits a negative temperature coefficient of −1.9 mV/K at 5 mA, enabling predictable drift compensation in bias networks. Its 390 pF capacitance at 1 MHz and 0.9 V forward voltage at 10 mA support high-frequency transient suppression and low-loss forward conduction paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - defines precise regulation threshold for low-voltage rail clamping |
| Tolerance | ±2 % - enables tighter control of reference accuracy vs. ±5 % variants in feedback loops |
| Differential Resistance (rdiff) | 375 Ω max at IZtest = 1 mA - determines regulation stiffness under small-signal current variation |
| Reverse Leakage (IR) | 5 µA max at VR = 1 V - minimizes quiescent current draw in always-on bias circuits |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling in standard layout |
| Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies junction-to-ambient heat transfer efficiency in unheatsinked SMD mounting |
| Temperature Coefficient (SZ) | −1.9 mV/K at IZ = 5 mA - enables predictable voltage drift correction in temperature-sensitive references |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, tin-plated copper terminals, marking bar indicating cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Ultra-small SOD882 footprint | 1.0 × 0.6 mm area saves >60 % board space vs. SOD323, enabling dense power management layouts |
| Low forward voltage | 0.9 V max at 10 mA - reduces conduction loss in series-connected ESD clamp configurations |
| Wide operating temperature range | −55 °C to +150 °C ambient - supports under-hood and industrial control module deployment |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) - allows cost/performance trade-off in voltage reference design |
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-C3V6,315 | ±5 % tolerance, higher max rdiff (500 Ω), same package and Ptot | Acceptable where 3.42–3.78 V range suffices; less suitable for tight-feedback loops | Select for cost-sensitive consumer applications where ±2 % accuracy is unnecessary |
| MMSZ4685T1G | 3.6 V nominal, ±5 %, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, non-AEC-Q101 | Larger footprint, higher power, no automotive qualification - suited for industrial mains-powered systems | Choose when higher surge margin is required and board space permits larger package |
Compared with BZX884-C3V6,315, the BZX884-B3V6,315 delivers tighter regulation and lower dynamic impedance for precision analog circuits; versus MMSZ4685T1G, it trades power headroom for AEC-Q101 compliance and 60 % smaller PCB area - critical for automotive modules with strict size constraints.

FAQ
What is the maximum reverse current at 1 V for BZX884-B3V6,315?
The maximum reverse current (IR) is 5 µA at VR = 1 V and Tj = 25 °C, per Table 7 of the official Nexperia datasheet Rev. 5. This low leakage ensures minimal power loss in always-on bias networks and supports accurate low-current sensing applications.
Is BZX884-B3V6,315 suitable for reflow soldering?
Yes - the SOD882 package is qualified exclusively for reflow soldering, with a recommended footprint defined in Figure 12 of the datasheet. Wave soldering is not supported due to thermal stress risks on the leadless structure and die attach integrity.
How does the −1.9 mV/K temperature coefficient affect circuit performance?
This negative coefficient means the Zener voltage decreases by 1.9 mV per Kelvin rise in junction temperature. In practice, it enables predictable drift compensation in voltage references - e.g., pairing with a positive-TC resistor network to achieve near-zero net drift over −40 °C to +125 °C.
Can BZX884-B3V6,315 replace BZX884-B3V3,315 in an existing design?
No direct substitution is recommended without circuit validation: BZX884-B3V3,315 has 3.23–3.37 V range (±2 %), while BZX884-B3V6,315 is 3.53–3.67 V - a 300 mV nominal shift that may violate regulation margins in feedback-controlled supplies or reference dividers.
