Product details
Overview
BZX884-C9V1,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 9.1 V nominal regulation at 5 mA, with 20 Ω typical differential resistance, 5.2 mV/K temperature coefficient, and 120 pF capacitance at 1 MHz. It delivers stable voltage reference and ESD protection in space-constrained automotive and industrial power rails.
For engineers reviewing the BZX884-C9V1,315 datasheet, BZX884-C9V1,315 pinout, BZX884-C9V1,315 application, or BZX884-C9V1,315 equivalent, key selection criteria include Zener voltage tolerance, junction-to-ambient thermal resistance (500 K/W), reverse leakage (500 nA at 6 V), surge capability (3 A non-repetitive peak), and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage under varying load and temperature conditions. Its 9.1 V nominal Zener voltage is specified at IZ = 5 mA, with ±5 % tolerance and 5.2 mV/K temperature coefficient ensuring predictable drift across −55 °C to +150 °C ambient range.
The device uses silicon planar technology in a leadless DFN1006-2 package, enabling ultra-low profile mounting and high-frequency performance. With 120 pF junction capacitance at 0 V and 500 nA reverse current at 6 V, it supports fast transient suppression and low-noise regulation in compact power management circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.92 V to 9.56 V at IZ = 5 mA - defines regulation window for precision biasing and reference applications |
| Differential Resistance (rdiff) | 20 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +5.2 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal stability analysis |
| Junction Capacitance (Cd) | 120 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and ESD response bandwidth |
| Reverse Leakage Current (IR) | 500 nA at VR = 6 V - sets minimum quiescent power loss in standby regulation paths |
| Non-repetitive Peak Reverse Current (IZSM) | 3 A at tp = 100 µs - defines single-event surge handling capacity for ESD protection |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - establishes thermal derating envelope for board-level layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B9V1,315 | ±2 % tolerance (vs. ±5 %), 20 Ω rdiff, identical package and thermal specs | Required where tighter regulation accuracy is needed for precision references or feedback loops | Select when system-level voltage error budget demands <±0.2 V deviation at 9.1 V nominal |
| MMSZ5240B-7-F | ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 200 mW Ptot, 100 pF Cd | Preferred where larger footprint is acceptable and higher surge current (>5 A) is required | Choose for legacy board compatibility or when thermal mass from larger package improves pulse energy handling |
Compared with BZX884-C9V1,315, the BZX884-B9V1,315 offers tighter voltage control but same thermal and surge limits, while MMSZ5240B-7-F trades miniaturization for higher surge robustness and different thermal resistance-making each suitable for distinct layout and accuracy priorities.

FAQ
What is the maximum continuous forward current for BZX884-C9V1,315?
The absolute maximum forward current is 200 mA per limiting values table. However, sustained operation above 10 mA forward current is not recommended, as the device is optimized for reverse-bias Zener operation. Forward conduction should be limited to brief pulses during circuit startup or fault conditions.
How does the 5.2 mV/K temperature coefficient affect regulation accuracy over temperature?
At 9.1 V nominal, a +5.2 mV/K coefficient means voltage increases ~0.47 V from −40 °C to +125 °C junction temperature. This drift is linear and predictable, enabling firmware compensation in closed-loop systems; for open-loop references, it contributes directly to total regulation error budget.
Can BZX884-C9V1,315 be used as a standalone ESD protector on USB data lines?
No-it is not designed for high-speed data line protection due to 120 pF capacitance, which would distort USB 2.0 signals. It is appropriate for low-frequency analog or power rail clamping, but dedicated low-capacitance TVS diodes (e.g., <5 pF) are required for data line ESD protection.
What is the thermal resistance from junction to ambient under standard mounting conditions?
Rth(j-a) is 500 K/W when mounted on an FR4 PCB with single-sided 60 µm copper, per Table 6. This value assumes the standard SOD882 footprint; thermal performance degrades significantly with smaller copper areas or no thermal relief, requiring derating above 25 °C ambient.
