Product details
Overview
BZX884S-B16-QYL from Nexperia is a Zener voltage regulator diode with 16 V nominal breakdown voltage (±2 % tolerance), housed in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package featuring side-wettable flanks. It delivers 365 mW total power dissipation at 25 °C on FR4 PCB, supports automotive-grade operation per AEC-Q101, and functions as a precision reference or overvoltage clamp in low-power analog supply rails.
For engineers reviewing the BZX884S-B16-QYL datasheet, BZX884S-B16-QYL pinout, BZX884S-B16-QYL application, or BZX884S-B16-QYL equivalent, key selection criteria include its 16 V ±2 % Zener voltage, 50 Ω typical differential resistance at IZ = 5 mA, −11.2 mV/K temperature coefficient, side-wettable flank compatibility for automated optical inspection (AOI), and AEC-Q101 qualification for under-hood electronics.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across load variations and input fluctuations. Its Zener voltage is specified at 5 mA test current with 50 Ω typical dynamic impedance, ensuring tight regulation under moderate current loads. The negative temperature coefficient (−11.2 mV/K) enables predictable thermal drift behavior in ambient ranges from −55 °C to +150 °C.
Designed for surface-mount assembly on standard FR4 PCBs with single-sided 70 μm copper, it relies on side-wettable flanks for solder joint quality verification via AOI. The 0.65 mm pitch, 1.0 mm × 0.6 mm × 0.47 mm body enables high-density placement in space-constrained automotive and portable electronics.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | ±5 % tolerance, SOT-23 package, 250 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer applications; lacks side-wettable flanks for AOI | Select when cost sensitivity outweighs automotive qualification and board space constraints |
| MMSZ4687 | ±5 % tolerance, SOD-123 package, 500 mW Ptot, AEC-Q101 qualified | Higher power rating but larger 2.7 mm × 1.4 mm footprint; less suitable for ultra-dense layouts | Choose when higher power margin is required and PCB real estate allows larger package |
Compared with BZX884S-B16-QYL, BZX84-C16 offers lower cost but sacrifices automotive qualification and precision; MMSZ4687 provides greater power headroom at the expense of 4.5× larger footprint, making the BZX884S-B16-QYL optimal for space-constrained AEC-Q101 designs requiring ±2 % regulation accuracy.

FAQ
What is the maximum reverse current at 15 V for BZX884S-B16-QYL?
At 15 V reverse bias and 25 °C, the typical reverse current is ≤0.05 μA, as confirmed in Table 8 of the datasheet. This ultra-low leakage ensures minimal power loss in standby modes and high-impedance sensing nodes where current draw must be sub-nanoampere.
Can BZX884S-B16-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages, causing current hogging when paralleled. The device is rated for 365 mW maximum dissipation on standard FR4; higher power requirements demand derating or alternative thermal management, not parallel connection.
Is the cathode marking visible after reflow soldering?
Yes - the cathode is indicated by a laser-marked bar on the top surface of the DFN1006BD-2 package, positioned adjacent to pin 1. Side-wettable flanks preserve mark visibility post-reflow, enabling post-solder AOI verification without X-ray inspection.
Does BZX884S-B16-QYL require a series resistor in all applications?
A series current-limiting resistor is mandatory in Zener regulator configurations to prevent thermal runaway. For 16 V regulation with 20 mA max load, a minimum 100 Ω resistor is required when supplied from 24 V - calculated using (VIN − VZ) / IZ(max) = (24 − 16) / 0.02 = 400 Ω, with safety margin applied.
