Product details
Overview
BZX8850-C13YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 13 V nominal with ±5 % tolerance. It delivers 12.35–13.65 V Zener voltage at IZ = 50 µA, exhibits 170 Ω differential resistance at IZ = 5 mA, and supports ≤250 mW total power dissipation on FR4 PCB. It is used in low-bias portable battery-powered circuits requiring stable reference voltage under light load.
For engineers reviewing the BZX8850-C13YL datasheet, BZX8850-C13YL pinout, BZX8850-C13YL application, or BZX8850-C13YL equivalent, this page provides verified Zener voltage, leakage behavior, thermal resistance, package dimensions, and validated alternative parts for low-power regulation design.
Technical Context
This Zener diode operates in reverse breakdown mode with specified regulation at ultra-low test current (50 µA), enabling use in standby and energy-sensitive circuits. Its intentional minor rise in leakage current improves switching speed and reduces noise per AN90031.
The device features a temperature coefficient of +7.0 mV/K and junction-to-ambient thermal resistance of 500 K/W on standard FR4 PCB - critical for thermal stability in compact layouts. Capacitance is 80 pF at VR = 0 V, f = 1 MHz, supporting moderate-frequency noise filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.35–13.65 V at IZ = 50 µA - defines precise regulation window for 13 V nominal reference |
| Differential Resistance rdiff | 170 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous bias power on standard FR4 PCB |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - ensures low conduction loss when used in forward-biased protection paths |
| Reverse Current IR | ≤ 0.05 µA at VR = 9.8 V - confirms tight leakage control below regulation threshold |
| Temperature Coefficient SZ | +7.0 mV/K - quantifies VZ drift per degree Celsius for thermal error budgeting |
| Diode Capacitance Cd | 80 pF at VR = 0 V, f = 1 MHz - impacts high-frequency bypass and noise suppression capability |

FAQ
What is the exact Zener voltage range for BZX8850-C13YL at 50 µA test current?
The BZX8850-C13YL has a guaranteed Zener voltage range of 12.35 V to 13.65 V when measured at IZ = 50 µA and Tj = 25 °C. This ±5 % tolerance is confirmed in Table 8 of the official Nexperia datasheet Rev. 1 (17 July 2024), and applies specifically to the 'C' series variant.
Can BZX8850-C13YL be used in forward conduction mode?
Yes - its forward voltage is specified at ≤0.9 V at IF = 10 mA, making it suitable for low-drop protection or polarity indication. However, it is not optimized for continuous forward current; absolute maximum forward current is 200 mA, and sustained operation above 10 mA requires thermal derating per the 500 K/W Rth(j-a) value.
How does the 'C' suffix differ from 'B' in the BZX8850 series?
The 'C' suffix denotes ±5 % Zener voltage tolerance and an intentional minor rise in leakage current optimized for faster switching and lower noise (per application note AN90031). In contrast, 'B' parts offer tighter ±2 % tolerance but lack the leakage optimization, resulting in higher noise and slower transient response in regulation paths.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies a JEDEC-standard reflow profile for the DFN1006-2 (SOD882) package. Figure 10 in the datasheet provides the recommended solder land pattern (0.6 mm pad length, 0.3 mm width, 0.7 mm center-to-center pitch), and the device is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1, allowing unlimited floor life before reflow.
