Product details
Overview
BZX884S-C20-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 20 V Zener voltage with ±5 % tolerance, 60 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C20-QYL datasheet, BZX884S-C20-QYL pinout, BZX884S-C20-QYL application, or BZX884S-C20-QYL equivalent, this page provides verified technical context, AEC-Q101-qualified specifications, side-wettable flank soldering guidance, and real-world use cases for automotive power rail clamping and low-power reference design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its 20 V nominal Zener voltage is specified at 5 mA test current, with a temperature coefficient of +14.4 mV/K and reverse leakage ≤0.05 μA at 15 V.
The device uses silicon planar technology in a leadless DFN1006BD-2 package with side-wettable flanks for automated optical inspection (AOI) compatibility. It supports continuous operation up to 365 mW total power dissipation on standard FR4 PCBs with 70 μm copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18.8 V to 21.2 V at IZ = 5 mA - defines stable regulation window for 20 V nominal rail |
| Differential Resistance (rdif) | 60 Ω typical at IZ = 5 mA - determines output impedance and voltage deviation under load change |
| Temperature Coefficient (SZ) | +14.4 mV/K - quantifies Zener voltage drift per degree Celsius rise in junction temperature |
| Reverse Leakage Current (IR) | ≤0.05 μA at VR = 15 V - ensures minimal standby power loss in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous DC or pulsed power handling capability |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction threshold when used in forward-biased ESD clamp configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B20-Q | ±2 % tolerance (tighter), higher differential resistance (80 Ω typ.), same 20 V nominal | Preferred where regulation stability under dynamic load is critical, e.g., precision DAC references | Select for improved voltage accuracy at expense of slightly higher output impedance |
| MMSZ5248B-TP | 20 V nominal, ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, no SWF | Suitable for non-automotive, space-tolerant designs requiring higher power margin | Choose when board space allows larger footprint and AEC-Q101 compliance is not required |
Compared with BZX884S-C20-QYL, the BZX884S-B20-Q offers tighter voltage control but reduced dynamic regulation performance, while MMSZ5248B-TP trades miniaturization and automotive qualification for higher power handling and legacy package compatibility.

FAQ
What is the maximum continuous reverse current the BZX884S-C20-QYL can sustain without degradation?
The device is rated for continuous operation at up to 200 mA forward current, but as a Zener diode it is intended for reverse-biased regulation. Its absolute maximum reverse power dissipation is 365 mW at 25 °C ambient on standard FR4. At 20 V, this corresponds to 18.25 mA average Zener current; sustained operation above this requires thermal derating per the 340 K/W junction-to-ambient thermal resistance.
How does the side-wettable flank (SWF) feature improve manufacturing yield?
The SWF design exposes solderable metal along both long edges of the DFN1006BD-2 package, enabling automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality from the side view. This eliminates blind spots inherent in traditional bottom-terminal-only packages and reduces field failures caused by insufficient solder joints in high-reliability automotive assembly lines.
Can BZX884S-C20-QYL be used in series or parallel configurations for higher voltage or current handling?
Series connection is feasible for higher voltage references (e.g., two 20 V devices for 40 V), but matching unit-to-unit VZ tolerance and tempco is critical to avoid unequal stress. Parallel operation is not recommended due to negative resistance characteristics and thermal runaway risk; discrete current-sharing resistors would be required, negating the benefit of the ultra-small footprint.
Is the 20 V Zener voltage specified at DC or pulsed test conditions?
The 20 V nominal Zener voltage is characterized under DC conditions at IZ = 5 mA, as confirmed in Table 8 of the datasheet. The quick reference data specifies forward voltage using a pulse test (tp ≤ 300 μs, duty cycle ≤ 0.02), but all Zener voltage parameters-including min/typ/max values and tempco-are based on steady-state DC measurements at Tj = 25 °C.
