Product details
Overview
BZX884-B15,315 from Nexperia is a ±2 % tolerance Zener diode with 15 V nominal regulation voltage, 250 mW total power dissipation, and SOD882 (DFN1006-2) ultra-small surface-mount package; used for precision voltage reference and ESD protection in space-constrained power rails and signal conditioning circuits.
For engineers reviewing the BZX884-B15,315 datasheet, BZX884-B15,315 pinout, BZX884-B15,315 application, or BZX884-B15,315 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low differential resistance (25 Ω at IZ = 5 mA), temperature coefficient (+10.7 mV/K), junction-to-ambient thermal resistance (500 K/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 15 V regulation at IZ = 5 mA, with a typical differential resistance of 25 Ω ensuring minimal voltage deviation under load variation. Its temperature coefficient of +10.7 mV/K indicates predictable positive drift over temperature, enabling accurate compensation in reference designs.
The device uses a planar silicon process in an unidirectional configuration with cathode-anode polarity defined by a marking bar on the SOD882 package. It supports non-repetitive peak reverse current up to 2 A (tp = 100 µs) and is rated for operation from −55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.7 V to 15.3 V at IZ = 5 mA - tight ±2 % tolerance enables high-accuracy voltage clamping and reference generation. |
| Differential Resistance (rdiff) | 25 Ω max at IZ = 5 mA - low impedance ensures stable regulation under dynamic load changes. |
| Temperature Coefficient (SZ) | +10.7 mV/K at IZ = 5 mA - predictable positive drift allows precise thermal compensation in analog references. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - defines maximum continuous steady-state power handling in standard layout. |
| Reverse Current (IR) | 50 nA max at VR = 10.5 V - ultra-low leakage preserves battery life and signal integrity in high-impedance bias networks. |
| Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 500 K/W - determines temperature rise per watt in free-air mounting; critical for thermal derating in compact layouts. |
| Non-repetitive Peak Reverse Current (IZSM) | 2 A at tp = 100 µs - supports transient surge suppression without degradation in ESD protection paths. |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small plastic surface-mount package measuring 1.0 × 0.6 × 0.5 mm, with exposed copper terminals on the bottom and a top-side marking bar indicating the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs at 15 V. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation and clamping functions. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring extended temperature and reliability compliance. |
| ±2 % Zener voltage tolerance | Enables use as a primary reference in precision analog circuits without post-calibration, reducing BOM count and test overhead. |
| SOD882 ultra-small footprint | 1.0 × 0.6 mm body size supports high-density routing in portable electronics, wearables, and miniaturized IoT nodes. |
| Low 25 Ω differential resistance | Maintains regulation stability across ±10 mA load current variation, critical for feedback loops in LDOs and DC-DC converters. |
| Ultra-low 50 nA reverse leakage | Minimizes standby current draw in always-on circuits such as real-time clock backup supplies and low-power microcontroller reset networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245B (ON Semiconductor) | Same 15 V nominal, ±5 % tolerance, SOT-23 package (2.9 × 1.3 × 1.0 mm), higher 350 mW Ptot, but larger footprint and no AEC-Q101 rating. | Acceptable for industrial non-automotive use where board space is less constrained and qualification is not required. | Select when higher power margin is needed and automotive qualification is unnecessary; avoid if SOD882 footprint or AEC-Q101 compliance is mandatory. |
| BZX84-C15 (Nexperia) | Same SOD882 package and 15 V nominal, but ±5 % tolerance (14.25–15.75 V), higher 50 Ω rdiff, and identical thermal specs. | Suitable for general-purpose clamping where tighter regulation is not critical, e.g., bulk rail protection rather than precision reference. | Choose for cost-sensitive, non-precision applications where ±5 % tolerance is acceptable and footprint compatibility is retained. |
Compared with MMBZ5245B and BZX84-C15, BZX884-B15,315 delivers superior voltage accuracy (±2 % vs. ±5 %), smaller footprint (1.0 × 0.6 mm vs. 2.9 × 1.3 mm), and automotive qualification-making it optimal for space-limited, safety-critical, or high-precision reference roles.

FAQ
What is the maximum continuous reverse current the BZX884-B15,315 can sustain at 25 °C?
The device has no specified maximum continuous reverse current; its steady-state limit is governed by power dissipation. At 25 °C ambient on FR4 PCB, it sustains up to 16.7 mA continuously (250 mW ÷ 15 V) before exceeding Ptot. Derating applies above 25 °C per the 500 K/W thermal resistance.
How does the +10.7 mV/K temperature coefficient affect circuit performance?
This coefficient means the Zener voltage increases by 10.7 mV per Kelvin rise in junction temperature. At 100 °C junction (75 °C above 25 °C reference), VZ rises by ~0.8 V - a predictable shift usable for temperature sensing or compensated reference design, but requiring layout-aware thermal management.
Can BZX884-B15,315 replace BZX84-C15 in existing SOD882 footprints?
Yes - both share identical SOD882 (DFN1006-2) mechanical dimensions and pinout (cathode/anode). However, BZX884-B15,315 offers ±2 % tolerance versus ±5 %, lower rdiff (25 Ω vs. 50 Ω), and AEC-Q101 qualification, making it a direct upgrade where tighter regulation or automotive compliance is needed.
What soldering profile is recommended for the SOD882 package?
Reflow soldering only is recommended, using JEDEC J-STD-020-compliant profiles. The footprint requires two 0.3 mm wide × 0.9 mm long solder pads with 0.7 mm spacing; peak temperature must not exceed 260 °C for ≤ 30 seconds to avoid die attach degradation or marking loss.
