Product details
Overview
BZX8850-C24YL from Nexperia is a low-current Zener voltage regulator diode in SOD882 (DFN1006-2) package, designed for precision voltage reference and low-power biasing in portable electronics. It delivers a nominal 24 V Zener voltage at 50 µA test current, with ±2 % tolerance, 250 mW total power dissipation, and 250 Ω differential resistance at 5 mA, enabling stable regulation in battery-powered sensor nodes and microcontroller reset circuits.
For engineers reviewing the BZX8850-C24YL datasheet, BZX8850-C24YL pinout, BZX8850-C24YL application, or BZX8850-C24YL equivalent, this page provides verified electrical characteristics, thermal limits, cathode/anode terminal mapping, and direct-fit alternatives for low-current voltage reference design in space-constrained PCBs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 24 V reference under low bias conditions (IZ = 50 µA), with temperature coefficient of +18.4 mV/K and junction-to-ambient thermal resistance of 500 K/W on FR4 PCB. Its ultra-small DFN1006-2 footprint (1.0 × 0.6 × 0.5 mm) supports high-density layouts while limiting forward voltage to ≤0.9 V at 10 mA.
The device exhibits 55 pF capacitance at 0 V and <0.05 µA reverse leakage at VR = 22 V, making it suitable for noise-sensitive analog front-ends. Its non-repetitive peak reverse power dissipation reaches 40 W for 100 µs pulses, supporting transient suppression in low-energy signal conditioning paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.8 V to 25.2 V at IZ = 50 µA - ensures tight 24 V reference under minimal bias current |
| Tolerance | ±2 % - enables accurate voltage setting without post-calibration in precision references |
| Differential Resistance (rdiff) | 250 Ω max at IZ = 5 mA - maintains low output impedance for stable regulation under load variation |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - minimizes conduction loss when used in forward-biased protection paths |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation across industrial ambient ranges without derating |
| Reverse Leakage (IR) | <0.05 µA at VR = 22 V - reduces quiescent current drain in always-on battery circuits |

FAQ
What is the maximum continuous reverse voltage that BZX8850-C24YL can regulate?
The BZX8850-C24YL is rated for continuous Zener operation up to its specified 24 V nominal voltage with ±2 % tolerance (22.8 V–25.2 V). Its absolute maximum reverse voltage is not defined separately; operation beyond 25.2 V risks exceeding the 250 mW power limit or triggering uncontrolled breakdown. Designers must ensure applied reverse voltage remains within this band under all operating conditions, including temperature-induced drift.
Can BZX8850-C24YL be used in forward conduction mode?
Yes, BZX8850-C24YL functions as a standard silicon diode in forward bias, with VF ≤ 0.9 V at 10 mA. However, its primary design purpose is reverse-bias Zener regulation. Forward use is limited to low-current protection or clamping roles-not rectification-due to its 200 mA absolute maximum forward current rating and lack of optimized forward recovery characteristics.
How does the ±2 % tolerance affect accuracy in a 24 V reference application?
At 24 V nominal, ±2 % tolerance means the actual Zener voltage falls between 22.8 V and 25.2 V at 50 µA. Combined with +18.4 mV/K temperature coefficient, worst-case drift over −40 °C to +85 °C adds ±2.3 V. Total potential error is ±3.5 V, so system-level calibration or trimming is recommended for applications demanding better than ±5 % absolute accuracy.
Is BZX8850-C24YL suitable for automotive applications?
No. BZX8850-C24YL is not automotive-qualified per Nexperia documentation. It lacks AEC-Q200 stress testing, extended temperature validation beyond −55 °C to +150 °C junction range, and automotive-specific reliability reporting. For automotive use, designers must select explicitly qualified parts such as the PZTA44 or BZX84-A24Q series, which undergo full qualification and include PPAP documentation.
