Product details
Overview
BZX884S-C62-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in compact automotive and industrial circuits. It delivers a nominal 62 V Zener voltage with ±5 % tolerance, 120 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature - enabling stable clamping in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the BZX884S-C62-QYL datasheet, BZX884S-C62-QYL pinout, BZX884S-C62-QYL application, or BZX884S-C62-QYL equivalent, this device is selected for its AEC-Q101 qualification, side-wettable flank (SWF) DFN1006BD-2 package for automated optical inspection (AOI), low reverse leakage (<0.05 μA at 49.6 V), and thermal resistance of 340 K/W on standard FR4 PCB.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 62 V (C-series, ±5 % tolerance). Its temperature coefficient is +80 mV/K at IZ = 2 mA, indicating positive drift with rising temperature - critical for thermal stability analysis in high-temperature environments like engine control units.
It features ultra-low capacitance (35 pF at 1 MHz, VR = 0 V) and a maximum forward voltage of 0.9 V at 10 mA, supporting fast transient response and minimal conduction loss in bidirectional protection schemes where forward conduction may occur during fault events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 58.0 V to 66.0 V at IZ = 2 mA - defines clamping threshold range for overvoltage protection in 48 V automotive systems. |
| Differential Resistance rdif | 120 Ω typical at IZ = 2 mA - determines regulation stiffness; lower values improve load regulation under varying current conditions. |
| Reverse Current IR | <0.05 μA at VR = 49.6 V - ensures negligible standby power loss in always-on monitoring circuits. |
| Power Dissipation Ptot | 365 mW on FR4 PCB (70 μm Cu) - sets maximum continuous clamping energy before thermal derating applies. |
| Junction Temperature Tj | −55 °C to +150 °C - supports operation in under-hood automotive locations and industrial motor drives. |
| Package Thermal Resistance Rth(j-a) | 340 K/W - quantifies self-heating under load; used to calculate ΔTj = P × Rth for reliability margining. |
| Capacitance Cd | 35 pF at f = 1 MHz, VR = 0 V - minimizes signal distortion in high-frequency sensing or communication line protection. |
Pinout & Package
DFN1006BD-2 (SOD882BD) leadless surface-mount package: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for solder joint inspection. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs at VZ. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation current flow. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - enables use in ASIL-B subsystems without additional qualification effort. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated terminals - improves manufacturing yield in high-volume SMT lines. |
| ±5 % voltage tolerance (C-series) | Provides cost-optimized regulation accuracy for non-critical biasing and clamping where tighter tolerance is unnecessary. |
| Ultra-small DFN1006BD-2 footprint | Reduces PCB area by >60 % vs. traditional SOD-123 - critical for space-constrained modules like battery management ICs and ADAS sensor nodes. |
| Low thermal resistance packaging | 340 K/W junction-to-ambient enables 365 mW dissipation without external heatsinking - simplifies thermal design in sealed enclosures. |
Applications
| Automotive Engine Control Unit (ECU) Power Rail Clamping | Industrial PLC Analog Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B62-Q | ±2 % tolerance (tighter), higher rdif (150 Ω typ), same VZ range and package | Preferred where tighter regulation is required, e.g., precision reference buffers | Select BZX884S-B62-Q when VZ accuracy better than ±5 % is mandatory; accept higher cost and slightly reduced regulation stiffness. |
| MMSZ5262ET1G | 62 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, no SWF | Suitable for non-automotive, higher-power applications with less stringent AOI requirements | Choose MMSZ5262ET1G only if board-level AOI is not required and PCB real estate allows larger footprint; avoid in AEC-Q101 designs. |
Compared with BZX884S-C62-QYL, the BZX884S-B62-Q offers superior voltage accuracy but lower regulation performance due to higher differential resistance, while the MMSZ5262ET1G trades miniaturization and automotive qualification for higher power handling and legacy package compatibility.

FAQ
What is the maximum continuous reverse current the BZX884S-C62-QYL can handle?
The device is rated for a maximum forward current of 200 mA per Absolute Maximum Ratings, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 62 V, sustained operation above ~5.9 mA (365 mW ÷ 62 V) requires thermal derating. For reliable long-term clamping, keep average IZ below 3 mA unless heatsinking is applied.
Does the BZX884S-C62-QYL require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit Zener current and prevent thermal runaway. For example, in a 75 V worst-case transient scenario, a 2.2 kΩ resistor limits peak IZ to ~5.9 mA, keeping power within the 365 mW rating. The resistor value must be calculated based on maximum expected input voltage and desired clamping current.
How does the +80 mV/K temperature coefficient affect circuit performance?
The positive temperature coefficient means VZ increases by ~80 mV per °C rise in junction temperature. In a 48 V system operating from −40 °C to +125 °C, VZ shifts from ~60.2 V to ~67.2 V. Designers must ensure downstream components tolerate this full range, especially in feedback loops where regulation setpoint drift impacts output accuracy.
Can the BZX884S-C62-QYL be used in parallel for higher power handling?
No - Zener diodes should not be paralleled due to mismatched VZ and temperature coefficients, causing current hogging and premature failure. For higher power, use a single higher-rated device (e.g., BZX884S-C62-Q with same specs but different suffix) or implement active clamping with MOSFETs and a precision reference.
