Product details
Overview
BZX884-B36,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 36 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 80 Ω typical differential resistance at 2 mA. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning and ESD protection circuits.
For engineers reviewing the BZX884-B36,315 datasheet, BZX884-B36,315 pinout, BZX884-B36,315 application, or BZX884-B36,315 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (500 K/W), reverse leakage at 25.2 V (≤50 nA), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown with a temperature coefficient of +33.0 mV/K at 2 mA, enabling stable regulation across −55 °C to +150 °C ambient. Its ultra-small DFN1006-2 footprint (1.0 × 0.6 × 0.5 mm) supports high-density PCB layouts while maintaining 150 °C maximum junction temperature capability.
The device exhibits ≤50 nA reverse current at 0.7 × VZnom (25.2 V), 35 Ω max differential resistance at 2 mA test current, and non-repetitive peak reverse current of 0.8 A for 100 µs pulses - critical for transient suppression in automotive and industrial interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.28 V min / 36.72 V max at IZ = 2 mA - defines tight regulation window for precision biasing |
| Tolerance | ±2% - enables accurate voltage reference without post-calibration in production |
| Differential Resistance (rdiff) | 80 Ω max at IZtest = 2 mA - ensures minimal output impedance under load variation |
| Reverse Current (IR) | ≤50 nA at VR = 25.2 V - guarantees low standby power loss in always-on circuits |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets thermal design boundary for derating |
| Thermal Resistance (Rth(j-a)) | 500 K/W - determines junction-to-ambient temperature rise per watt dissipated |
| Non-repetitive Peak Reverse Current | 0.8 A at tp = 100 µs - defines surge-handling capability for ESD events |
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.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C36,315 | ±5% tolerance (34.2–37.8 V range), higher 90 Ω max rdiff, same package and Ptot | Acceptable where cost sensitivity outweighs precision; not suitable for ASIL-B systems | Select when budget constraints dominate and ±5% regulation accuracy suffices |
| MMSZ5226B-7-F | ±5% tolerance, SOD-123 package (2.7 × 1.4 × 1.0 mm), 500 mW Ptot, 100 Ω rdiff | Larger footprint allows higher power handling but incompatible with ultra-dense layouts | Choose when thermal margin >250 mW is required and board space permits larger package |

FAQ
What is the maximum allowable junction temperature for BZX884-B36,315?
The absolute maximum junction temperature is 150 °C, verified per IEC 60134 limiting values. This rating assumes proper PCB thermal design using the SOD882 standard footprint on FR4 with 60 µm copper. Operation above this temperature risks permanent parametric shift or catastrophic failure.
How does the ±2% tolerance affect regulation accuracy in a 36 V reference circuit?
At 25 °C and 2 mA test current, the Zener voltage ranges from 35.28 V to 36.72 V - a 1.44 V span. This tolerance directly defines worst-case output deviation in shunt regulator configurations, requiring downstream circuitry to accommodate this band without performance loss.
Can BZX884-B36,315 be used for bidirectional ESD protection?
No - it is a unidirectional Zener diode configured only for reverse-bias operation. For bidirectional ESD clamping, a dedicated TVS diode such as PESD5V0S1BA must be used; BZX884-B36,315 conducts only when cathode is biased positive relative to anode.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The package supports JEDEC J-STD-020-compliant profiles with peak temperatures up to 260 °C, provided the solder paste stencil and pad layout follow Figure 12 in the datasheet (0.3 mm solder mask opening, 0.6 mm pad width).
