Product details
Overview
BZX8850-C7V5YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 7.5 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, features 80 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range. Used in portable battery-powered sensor biasing and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-C7V5YL datasheet, BZX8850-C7V5YL pinout, BZX8850-C7V5YL application, or BZX8850-C7V5YL equivalent, this page provides verified electrical parameters, thermal behavior, package dimensions, cathode/anode terminal mapping, and validated alternative Zener options for low-bias regulation.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 7.5 V at IZ = 50 µA, exhibiting a temperature coefficient of +2.5 mV/K and diode capacitance of 150 pF at 0 V. Its differential resistance drops to 80 Ω at 5 mA, enabling tighter regulation under light load conditions.
The device uses silicon planar technology in an ultra-small leadless DFN1006-2 package with exposed copper terminals, optimized for minimal parasitic inductance and thermal resistance of 500 K/W (junction-to-ambient, FR4 PCB). Cathode identification is via top-side marking bar.
Key Specifications

| Zener voltage VZ | 7.13 V to 7.88 V at IZ = 50 µA - ensures ±2 % regulation accuracy for low-power references |
| Differential resistance rdiff | 80 Ω max at IZ = 5 mA - maintains stable output under varying load currents up to 200 mA |
| Forward voltage VF | 0.9 V max at IF = 10 mA - enables predictable forward conduction during transient clamping |
| Total power dissipation Ptot | 250 mW at Tamb ≤ 25 °C - supports continuous operation on standard FR4 PCB without heatsinking |
| Junction temperature Tj | −55 °C to +150 °C - suitable for industrial and extended-temperature embedded environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | Same 7.5 V ±2 % rating but in SOT-23 package; higher rdiff (100 Ω) and larger footprint (3.0 × 1.4 mm) | Less suitable for ultra-dense layouts; higher thermal resistance (350 K/W) limits power handling on thin PCBs | Select when legacy SOT-23 assembly infrastructure exists and board space permits |
| MMSZ5236B | 7.5 V ±5 % tolerance; 100 Ω rdiff; SOD-123 package; 500 mW Ptot | Higher power capability but looser tolerance and greater leakage (1 µA at 5.7 V) | Choose only where cost sensitivity outweighs regulation accuracy and battery leakage requirements |
Compared with BZX8850-C7V5YL, BZX84-C7V5 trades miniaturization for assembly compatibility, while MMSZ5236B sacrifices precision and leakage performance for higher power margin-making the BZX8850-C7V5YL optimal for space-constrained, low-quiescent-current designs.

FAQ
What is the maximum reverse current at 5.7 V for BZX8850-C7V5YL?
The maximum reverse current (IR) is 0.1 µA at VR = 5.7 V and Tj = 25 °C, as specified in Table 8. This ultra-low leakage ensures minimal battery drain in always-on sensing applications and supports multi-year operation in energy-harvesting systems without compromising regulation stability.
Can BZX8850-C7V5YL be used in place of a 7.5 V TL431 shunt regulator?
No-it is not a drop-in replacement. The BZX8850-C7V5YL is a two-terminal passive Zener diode requiring external current limiting, whereas the TL431 is a three-terminal active shunt regulator with adjustable output and built-in error amplifier. Use the Zener only in simple fixed-voltage clamp or reference roles where no feedback control is needed.
What is the thermal resistance from junction to ambient for this device?
Rth(j-a) is 500 K/W when mounted on a single-sided FR4 PCB with standard footprint and tin-plated copper, per Table 6. This value assumes no thermal vias or copper pour; adding 2–4 thermal vias beneath the pad can reduce effective Rth by 30–40 % in production layouts.
Does the "YL" suffix indicate tape-and-reel packaging?
Yes-the "YL" suffix denotes 10,000-piece tape-and-reel packaging per IEC 60286-3 standard, with 8 mm carrier tape width and 4 mm pocket pitch. This format is compatible with high-speed pick-and-place equipment and supports automated SMT assembly for volume production runs.
