Product details
Overview
BZX884-B9V1,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 9.1 V nominal regulation at 5 mA, with 250 mW total power dissipation and 120 pF capacitance at 1 MHz. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX884-B9V1,315 datasheet, BZX884-B9V1,315 pinout, BZX884-B9V1,315 application, or BZX884-B9V1,315 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (500 K/W), reverse leakage (500 nA at 6 V), differential resistance (20–100 Ω), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its 9.1 V nominal Zener voltage is specified at IZ = 5 mA, with temperature coefficient of +5.2 mV/K and typical differential resistance of 20 Ω at 5 mA test current.
The device uses silicon planar epitaxial construction and is optimized for high-frequency stability, with capacitance limited to 120 pF at 0 V reverse bias and 1 MHz. Its ultra-small DFN1006-2 footprint enables dense PCB layouts in space-constrained applications such as portable sensor interfaces and automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.92–9.28 V at IZ = 5 mA; ensures tight regulation window for 9.1 V reference designs |
| Tolerance | ±2 % (B-series); supports precision biasing and feedback networks requiring <2.5% error budget |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C; limits continuous current to ~27 mA at 9.1 V without derating |
| Differential Resistance (rdiff) | 20–100 Ω at IZ = 5 mA; determines output impedance and load regulation sensitivity |
| Reverse Leakage (IR) | 500 nA at VR = 6 V; minimizes quiescent current in always-on monitoring circuits |
| Capacitance (Cd) | 120 pF at f = 1 MHz, VR = 0 V; enables use in <100 MHz signal path clamping without excessive loading |
| Temperature Coefficient (SZ) | +5.2 mV/K at IZ = 5 mA; allows predictable drift compensation in temperature-stable references |
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 pads for thermal conduction and reflow-compatible solder lands per JEDEC MO-229 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; polarity must be observed to ensure reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms current return path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and body control modules requiring extended temperature cycling and humidity resistance |
| Ultra-small DFN1006-2 footprint | Enables placement in <1.5 mm² board area-critical for wearable sensors and multi-rail PMIC monitoring |
| Low 120 pF junction capacitance | Preserves signal integrity in RF front-end ESD protection and high-speed ADC reference decoupling |
| 250 mW power rating on FR4 | Supports transient surge handling up to 3 A peak (100 µs) while maintaining long-term reliability on standard PCBs |
| ±2% Zener voltage tolerance | Reduces need for post-assembly trimming in factory-calibrated industrial sensor transmitters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C9V1,315 | ±5% tolerance (vs. ±2%); higher max rdiff (100 Ω vs. 20–100 Ω); identical package and power rating | Acceptable where cost-sensitive consumer products tolerate wider regulation band (8.55–9.45 V) | Select when absolute voltage accuracy is secondary to BOM consolidation across multiple Zener voltages |
| MMSZ4687T1G | ±5% tolerance; SOD-123 package (2.7 × 1.6 mm); 500 mW Ptot; 100 pF Cd | Higher power handling but 2.7× larger footprint; better for high-surge industrial I/O protection | Choose when board space permits and >250 mW surge energy absorption is required |
Compared with BZX884-C9V1,315, the BZX884-B9V1,315 offers tighter regulation critical for metrology-grade references; versus MMSZ4687T1G, it trades power margin for 60% smaller footprint-ideal for miniaturized battery-powered systems.

FAQ
What is the maximum reverse current at 6 V for BZX884-B9V1,315?
The maximum reverse leakage current is 500 nA at VR = 6 V and Tj = 25 °C, measured per Table 7 of the datasheet. This low leakage supports ultra-low-power applications like coin-cell-powered monitors where standby current must remain below 1 µA.
Can BZX884-B9V1,315 be used in place of a 9.1 V Zener with ±5% tolerance?
Yes, but only where tighter regulation is beneficial: its ±2% tolerance (8.92–9.28 V) improves accuracy over ±5% parts (8.65–9.56 V). However, design margins must accommodate its higher positive temperature coefficient (+5.2 mV/K), which increases voltage drift above 25 °C relative to ±5% variants.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes-the SOD882 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The recommended footprint (Fig. 12) uses 0.3 mm wide solder lands and 0.7 mm pad spacing; thermal relief is unnecessary due to the device's low thermal mass and 500 K/W junction-to-ambient resistance.
Does BZX884-B9V1,315 support bidirectional ESD protection?
No-it is a unidirectional Zener diode configured for reverse-bias regulation only. For bidirectional ESD clamping (e.g., USB data lines), a dedicated TVS array like PESD5V0S1BA should be used; this part provides symmetric ±5 V clamping and sub-nanosecond response.
