Product details
Overview
BZX8850S-C24-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision voltage reference and clamping in space-constrained, low-power circuits. It delivers a nominal 24 V regulation at 50 µA test current, with ±5 % tolerance, 250 Ω differential resistance at 5 mA, and 0.05 µA reverse leakage at 18.4 V, targeting battery-powered sensor nodes and automotive body electronics.
For engineers reviewing the BZX8850S-C24-QYL datasheet, BZX8850S-C24-QYL pinout, BZX8850S-C24-QYL application, or BZX8850S-C24-QYL equivalent, key selection criteria include its ultra-small DFN1006BD-2 package, AEC-Q101 qualification, low 50 µA regulation test current, and intentional leakage optimization for noise-sensitive analog front-ends.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load and temperature conditions. Its regulation is specified at IZ = 50 µA - significantly lower than standard Zeners - enabling operation in micro-power systems where bias current must be minimized.
The device features two tolerance grades (±2 % for 'B' series, ±5 % for 'C' series), with the 'C' suffix indicating the wider tolerance variant. The BZX8850S-C24-QYL belongs to the 'C' group and exhibits a temperature coefficient of +18.4 mV/K, supporting predictable drift compensation in thermal-aware designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 24 V at IZ = 50 µA - defines primary regulation point for low-bias reference circuits |
| Tolerance | ±5 % - allows cost-optimized selection where tight voltage accuracy is not required |
| Differential Resistance | 250 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current | 0.05 µA at VR = 18.4 V - enables ultra-low standby power in always-on monitoring circuits |
| Forward Voltage | 0.9 V at IF = 10 mA - supports use as a low-drop clamp or ESD protection element in forward bias |
| Total Power Dissipation | 365 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| Junction Temperature | 150 °C - ensures reliability in under-hood automotive environments per AEC-Q101 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B24-Q | ±2 % tolerance (vs. ±5 %), tighter 22.8–25.2 V range, higher cost | Required where reference stability dominates cost and board area constraints | Select when system-level calibration budget is insufficient to compensate for ±5 % variation |
| MMSZ5245B-TP | Same 24 V nominal, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, no AEC-Q101 | Suitable for industrial but not automotive-grade designs due to qualification gap | Choose only if larger footprint is acceptable and automotive qualification is unnecessary |
Compared with BZX8850S-B24-Q, the C24 variant trades voltage precision for cost and size efficiency; versus MMSZ5245B-TP, it offers 45 % smaller footprint and automotive qualification at the expense of 135 mW lower power rating.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-C24-QYL?
The nominal Zener voltage is 24 V, with a guaranteed range of 22.8 V to 25.2 V at IZ = 50 µA. Breakdown begins within this band; operation below 22.8 V yields negligible reverse current (<0.05 µA), while exceeding 25.2 V risks exceeding limiting values. Absolute maximum reverse voltage is not defined - the device is rated by Zener characteristics, not blocking voltage.
Can BZX8850S-C24-QYL be used in forward bias as a regular diode?
Yes - it exhibits a forward voltage of 0.9 V at 10 mA, consistent with silicon PN junction behavior. However, it is not optimized for rectification: its 200 mA absolute maximum forward current and lack of soft recovery make it unsuitable for switching or power conversion. Use is limited to low-current clamping or indicator functions.
How does the 'QYL' suffix differ from standard 'Q' in ordering?
'QYL' denotes a specific tape-and-reel packaging variant per Nexperia's internal logistics coding: 10,000 units per reel, 8 mm carrier tape, 4 mm pocket depth, and RoHS-compliant matte tin finish. The electrical and mechanical specifications are identical to BZX8850S-C24-Q; only packaging and traceability metadata differ.
Is thermal resistance data available for PCB layouts other than single-sided FR4?
No - the datasheet specifies Rth(j-a) = 340 K/W only for a single-sided, tin-plated FR4 board with standard footprint. No characterization is provided for double-sided copper, thermal vias, or metal-core substrates. For enhanced thermal performance, users must perform empirical measurement or simulation using the given baseline as anchor.
