Product details
Overview
BZX8850S-B13-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision voltage reference and regulation in space-constrained, low-power circuits. It delivers a nominal 13 V Zener voltage (12.7–13.3 V at IZ = 50 µA), ±2 % tolerance (B-series), 365 mW total power dissipation, and features side-wettable flanks for automated optical solder-joint inspection - ideal for automotive body electronics and portable sensor nodes.
For engineers reviewing the BZX8850S-B13-QYL datasheet, BZX8850S-B13-QYL pinout, BZX8850S-B13-QYL application, or BZX8850S-B13-QYL equivalent, key selection criteria include its ultra-low test current (50 µA), AEC-Q101 qualification, DFN1006BD-2 package footprint, and intentional leakage optimization for fast switching and noise reduction per AN90031.
Technical Context
This device operates as a two-terminal reverse-biased Zener diode with a specified breakdown voltage of 12.7–13.3 V at 50 µA test current and differential resistance ≤170 Ω at 5 mA. Its temperature coefficient is +7.0 mV/K, enabling stable regulation across −55 °C to +150 °C ambient range.
The diode exhibits low capacitance (≤80 pF at 0 V, f = 1 MHz) and low reverse current (≤0.05 µA at VR = 11 V), supporting high-frequency noise suppression and battery-sensitive biasing. Its thermal resistance (junction-to-ambient) is 340 K/W on standard FR4 PCB, limiting continuous power handling at elevated temperatures.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | ±5 % tolerance, SOT23 package (2.9 mm × 1.3 mm), 350 mW Ptot, no AEC-Q101 qualification | Larger footprint, higher thermal resistance (~450 K/W), unsuitable for automotive production | Select only for cost-sensitive industrial prototypes where size and qualification are secondary |
| MMSZ4687 | ±5 % tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW Ptot, no SWF, not AEC-Q101 qualified | Higher power rating but incompatible with AOI and automotive reliability requirements | Prefer when higher surge energy handling is needed and board space permits larger package |
Compared with BZX8850S-B13-QYL, BZX84-C13 and MMSZ4687 offer wider tolerance and larger packages without side-wettable flanks or automotive qualification - making them viable only in non-safety-critical, non-AOI-dependent, or non-automotive contexts where footprint and long-term reliability are less constrained.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX8850S-B13-QYL has a nominal Zener voltage of 13 V, with guaranteed breakdown occurring between 12.7 V and 13.3 V at 50 µA test current. Its absolute maximum reverse voltage is not defined separately - operation above 13.3 V under regulation conditions risks exceeding power limits or thermal runaway. The device is rated for non-repetitive peak reverse power up to 40 W for 100 µs pulses.
Is this part suitable for use in a 12 V automotive system with load-dump transients?
No - BZX8850S-B13-QYL is not rated for load-dump protection. Its 365 mW continuous power dissipation and 40 W non-repetitive surge rating are insufficient for ISO 7637-2 Pulse 5a (up to 120 V, 400 ms). It is intended for steady-state voltage reference and low-energy clamping only. Use dedicated TVS diodes like P6SMB13A for load-dump suppression.
How does the "intentional minor rise of leakage current" affect circuit performance?
Per AN90031, the controlled increase in leakage improves junction response time and reduces high-frequency noise generation during regulation transitions. This enhances stability in fast-switching analog circuits and reduces EMI in sensitive measurement paths - without degrading DC accuracy or long-term reliability under specified operating conditions.
Can this diode be used in parallel for higher current capability?
No - Zener diodes exhibit negative temperature coefficients and parameter spread; paralleling BZX8850S-B13-QYL units causes current hogging and thermal imbalance. For higher current regulation, use a single higher-power Zener (e.g., BZX85-C13 in DO-35) or implement an active shunt regulator with a transistor and reference diode.
