Product details
Overview
BZX8850-B7V5YL 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-ideal for battery-powered sensor nodes and portable IoT device power rails.
For engineers reviewing the BZX8850-B7V5YL datasheet, BZX8850-B7V5YL pinout, BZX8850-B7V5YL application, or BZX8850-B7V5YL equivalent, this page provides verified Zener voltage, thermal resistance, leakage behavior, cathode/anode terminal mapping, and direct-fit alternatives for low-power voltage reference design.
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 typical capacitance of 150 pF at 0 V. Its low test current enables minimal quiescent power draw in always-on monitoring circuits.
The device uses silicon planar technology with controlled doping to achieve tight ±2 % voltage tolerance and low dynamic impedance (80 Ω at 5 mA). Its DFN1006-2 package provides thermal resistance of 500 K/W to ambient on FR4 PCB, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.35 V to 7.65 V at IZ = 50 µA - ensures stable 7.5 V reference under ultra-low bias conditions |
| Differential Resistance rdiff | 80 Ω max at IZ = 5 mA - maintains voltage stability against load current variations |
| Temperature Coefficient SZ | +2.5 mV/K - predictable positive drift supports temperature-compensated reference designs |
| Reverse Current IR | 0.1 µA max at VR = 5.7 V - enables low-leakage standby operation in energy-sensitive systems |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines forward conduction threshold for polarity-aware protection |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| Junction Temperature Tj | 150 °C max - defines upper thermal limit for sustained operation without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | ±5 % tolerance, SOT23 package (3.0 × 1.4 mm), 350 mW Ptot, rdiff = 100 Ω | Larger footprint, higher power, looser tolerance - suitable for non-critical biasing where board space is not constrained | Select when higher surge robustness and easier hand-soldering are prioritized over miniaturization |
| MMSZ5235B | ±5 % tolerance, SOD-123 package (3.7 × 1.6 mm), 500 mW Ptot, rdiff = 15 Ω at 20 mA | Higher power rating and lower impedance at high current - better for moderate-load regulation but incompatible with ultra-low-IZ use cases | Choose for applications requiring tighter regulation under >1 mA loads, accepting larger size and higher leakage |
Compared with BZX8850-B7V5YL, BZX84-C7V5 trades miniaturization and low-current precision for ease of assembly and surge margin, while MMSZ5235B sacrifices low-bias efficiency for improved dynamic regulation at higher currents-making the BZX8850-B7V5YL uniquely suited for space- and energy-constrained Zener reference roles.

FAQ
What is the Zener voltage tolerance for BZX8850-B7V5YL?
The BZX8850-B7V5YL has a nominal Zener voltage of 7.5 V with a ±2 % tolerance, meaning its actual breakdown voltage falls between 7.35 V and 7.65 V when measured at 50 µA test current and 25 °C ambient temperature, as confirmed in Table 8 of the official Nexperia datasheet Rev. 1 (2024).
Can BZX8850-B7V5YL be used in place of a 7.5 V Zener with higher power rating?
No-it is rated for 250 mW total power dissipation on FR4 PCB and optimized for low-current operation (50 µA test point). Substituting it for higher-power Zeners (e.g., 500 mW types) risks thermal overload under >1 mA loads; its 80 Ω differential resistance also implies greater voltage shift under load than higher-rated devices.
How is cathode identification implemented on the SOD882 package?
The cathode is marked by a visible bar on the top surface of the DFN1006-2 package, aligned with Pin 1 as shown in Figure 9 of the datasheet. This marking corresponds directly to the cathode terminal (K) in the pinning diagram and must be oriented toward the regulated output node in PCB layout.
Does BZX8850-B7V5YL meet automotive qualification standards?
No-this part is not automotive-qualified. The Nexperia datasheet explicitly states in Section 14 that unless otherwise specified, products are "non-automotive qualified" and not tested to AEC-Q200. It is intended for industrial, consumer, and portable electronics-not safety-critical vehicle systems.
