Product details
Overview
BZX884-B2V7,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 2.65–2.75 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides precise low-voltage regulation and ESD protection in space-constrained PCB layouts.
For engineers reviewing the BZX884-B2V7,315 datasheet, BZX884-B2V7,315 pinout, BZX884-B2V7,315 application, or BZX884-B2V7,315 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance - all critical for low-voltage biasing, clamping, and transient suppression design validation.
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled 2.65–2.75 V nominal voltage at IZ = 5 mA, exhibiting a negative temperature coefficient of −1.4 mV/K. Its low 300–450 Ω differential resistance ensures stable regulation under varying load currents.
Designed for surface-mount reliability, it features ultra-small 1.0 × 0.6 × 0.5 mm DFN1006-2 packaging, cathode-marked top-side orientation, and FR4 PCB thermal performance validated at Rth(j-a) = 500 K/W under standard footprint conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.65–2.75 V at IZ = 5 mA - defines precise low-voltage reference for bias networks and clamp thresholds |
| Tolerance | ±2% - enables tighter regulation margin vs. ±5% variants in precision analog circuits |
| Differential Resistance (rdiff) | 300–450 Ω at IZ = 1 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | 20 µA at VR = 1 V - limits standby current in always-on sensing or monitoring rails |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC or pulsed power handling on standard FR4 |
| Temperature Coefficient (SZ) | −1.4 mV/K at IZ = 5 mA - quantifies voltage drift over operating temperature range |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low-loss conduction in forward-biased protection paths |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, with exposed copper terminals and cathode indicated by a top-side marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock |
| Ultra-small DFN1006-2 footprint | Enables placement in high-density layouts where traditional SOD-323 or DO-35 packages cannot fit |
| 250 mW power rating | Supports sustained clamping in low-energy transients without derating below 85 °C ambient |
| 2.4–75 V E24 voltage range | Provides standardized Zener options across common system rail voltages (e.g., 3.3 V, 5 V, 12 V) |
| Low 20 µA reverse leakage @ 1 V | Minimizes quiescent current draw in battery-powered sensor nodes and always-on regulators |
Applications
| Automotive Sensor Biasing | USB Port ESD Clamping |
|---|---|
Use Scenario: Providing stable 2.7 V reference to MEMS pressure sensor ICs in engine control modules. IC Role / Device Role / Timing Role: Zener diode acts as shunt regulator, maintaining constant bias voltage despite supply ripple and load variation. Use Value: Enables <1% full-scale error in analog sensor output by stabilizing excitation voltage against 12 V rail fluctuations. |
Use Scenario: Protecting USB 2.0 data lines (D+/D−) from ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Fast-switching Zener clamps transient voltage to <3.3 V before it reaches PHY transceiver inputs. Use Value: Limits peak line voltage to safe levels within 1 ns response time, preserving signal integrity and preventing latch-up. |
| Industrial PLC Input Conditioning | Low-Power IoT Node Voltage Reference |
Use Scenario: Regulating 2.7 V supply for optocoupler input stages in 24 V industrial digital input modules. IC Role / Device Role / Timing Role: Shunt regulator absorbs excess current from series resistor, fixing voltage across LED anode-cathode. Use Value: Ensures consistent LED forward current across 18–30 V input range, guaranteeing reliable optical coupling. |
Use Scenario: Generating stable 2.7 V reference for ADC in coin-cell-powered environmental sensor nodes. IC Role / Device Role / Timing Role: Low-leakage Zener supplies reference voltage to SAR ADC while drawing <1 µA in sleep mode. Use Value: Extends 10-year battery life by limiting reference circuit current to sub-µA level during measurement intervals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C2V7,315 | ±5% tolerance (2.57–2.84 V), higher max reverse leakage (30 µA @ 1 V) | Acceptable where cost sensitivity outweighs tight voltage stability requirements | Select for non-critical biasing where ±5% regulation margin is sufficient and BOM cost reduction is prioritized |
| MMSZ4678T1G | ±5% tolerance, SOD-123 package (1.8 × 1.4 × 1.0 mm), 500 mW Ptot, 2.6–2.8 V range | Higher power handling but 3× larger footprint; not AEC-Q101 qualified | Choose only when board space permits larger package and automotive qualification is not required |
Compared with BZX884-B2V7,315, the ±5% C-series variant trades voltage precision for cost, while MMSZ4678T1G sacrifices automotive qualification and miniaturization for higher power capacity - making the BZX884-B2V7,315 optimal for space- and reliability-constrained automotive and portable designs.

FAQ
What is the maximum continuous reverse current the BZX884-B2V7,315 can sustain without degradation?
The device supports up to 200 mA forward current (IF) but is not rated for continuous reverse conduction. Its specified Zener test current is 5 mA; sustained operation above 20 mA requires thermal derating per the 500 K/W junction-to-ambient resistance and 150 °C max junction temperature limit.
How does the −1.4 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over that 165 K range, the Zener voltage shifts by approximately −231 mV (−1.4 × 165), resulting in a final VZ of ~2.52 V at +125 °C. This drift is fully characterized in Figure 6 of the datasheet and must be accounted for in precision reference designs.
Can BZX884-B2V7,315 replace a 2.7 V TL431-based shunt regulator?
No - the TL431 is an adjustable 2.5 V precision shunt regulator with active feedback and 0.5% initial tolerance; BZX884-B2V7,315 is a passive two-terminal Zener with ±2% tolerance and no feedback path. It lacks the accuracy, programmability, and dynamic response needed for closed-loop regulation.
Is the SOD882 package compatible with standard reflow soldering profiles for lead-free assembly?
Yes - Nexperia specifies reflow soldering as the only recommended method, with validated thermal profiles aligned to J-STD-020. The SOD882 footprint in Figure 12 supports IPC-7351-compliant land patterns and withstands peak temperatures up to 260 °C for ≤30 seconds.
