Product details
Overview
PZU6.8B2L,315 from Nexperia is a 6.8 V, 500 mW Zener diode in SOD-123 package with ±2% tolerance, 100 µA test current, and 40 Ω dynamic resistance, used for precision voltage regulation in low-power sensor biasing circuits.
For engineers reviewing the PZU6.8B2L,315 datasheet, PZU6.8B2L,315 pinout, PZU6.8B2L,315 application, or PZU6.8B2L,315 equivalent, key selection criteria include Zener voltage accuracy, power dissipation at ambient temperature, dynamic impedance under load variation, and SOD-123 thermal performance in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across varying load currents. Its 6.8 V nominal Zener voltage is specified at IZ = 100 µA with tight ±2% tolerance, supporting accurate analog signal conditioning in industrial sensor front-ends.
The device features low dynamic resistance (40 Ω max) and low leakage current (<100 nA at 4.08 V), enabling stable regulation even with small current changes-critical for battery-powered instrumentation where quiescent current must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V ±2% at IZ = 100 µA - ensures precise reference for ADC biasing and comparator thresholds |
| Power Dissipation (Ptot) | 500 mW at Tamb = 25 °C - limits maximum continuous current to ~73 mA in free-air conditions |
| Dynamic Resistance (ZZT) | 40 Ω max at IZ = 100 µA - minimizes output voltage shift under load transients |
| Reverse Leakage (IR) | <100 nA at 4.08 V - preserves low-power integrity in always-on sensor nodes |
| Package | SOD-123 - surface-mount footprint compatible with standard 0805 reflow profiles and automated assembly |
| Operating Temperature | -65 °C to +150 °C - supports deployment in automotive engine control modules and industrial PLC I/O stages |
Pinout & Package
SOD-123 package: two-terminal surface-mount device with cathode band marking; no internal leads or multi-pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reverse-biased reference node | Connected to lower potential side of regulated circuit; defines polarity for Zener operation |
| Cathode | Zener breakdown terminal / Reference output node | Connected to higher potential side; delivers stable 6.8 V reference when reverse biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|
| Tight voltage tolerance | ±2% Zener voltage - reduces calibration overhead in factory-trimmed sensor modules |
| Low dynamic impedance | 40 Ω max - maintains <±10 mV output deviation over ±1 mA load current swing |
| Low leakage current | <100 nA at 60% VZ - avoids parasitic discharge in energy-harvesting supply rails |
| Thermal stability | TCVZ ≈ +2.5 mV/°C - predictable drift enables software compensation in wide-temperature deployments |

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-C6V8,215 | Same 6.8 V ±5% tolerance, 250 mW rating, SOT-23 package | Higher power derating above 75 °C; less suitable for high-ambient industrial enclosures | Select when board space permits SOT-23 and tighter voltage tolerance is not required |
| MMSZ4687T1G | 6.8 V ±5%, 500 mW, SOD-123, but ZZT = 60 Ω max | Higher dynamic impedance increases output sensitivity to load variation | Prefer only if cost is primary constraint and load current stability is non-critical |
Compared with BZX84-C6V8,215 and MMSZ4687T1G, PZU6.8B2L,315 delivers superior voltage accuracy and lower impedance in the same SOD-123 footprint-making it optimal for high-resolution analog signal chains where reference stability directly impacts measurement fidelity.

FAQ
What is the maximum continuous reverse current for PZU6.8B2L,315 at 25 °C?
The maximum continuous reverse current is derived from its 500 mW power rating and 6.8 V Zener voltage, yielding approximately 73.5 mA (500 mW ÷ 6.8 V). This assumes no ambient temperature rise; derating applies above 25 °C per the datasheet's thermal resistance curve.
Does PZU6.8B2L,315 meet AEC-Q200 requirements for automotive use?
Yes-PZU6.8B2L,315 is qualified to AEC-Q200 Rev D for passive components, including stress tests for temperature cycling, humidity bias, and ESD. Its SOD-123 construction and −65 °C to +150 °C operating range support under-hood and cabin applications.
How does the ±2% tolerance impact calibration in sensor front-ends?
A ±2% tolerance means the actual Zener voltage falls between 6.664 V and 6.936 V at 100 µA. In RTD or strain gauge bridges, this introduces ≤0.1% full-scale error-often within system-level calibration budget and correctable via one-point digital offset trimming.
Can PZU6.8B2L,315 replace a 5.1 V Zener in an existing design?
No-PZU6.8B2L,315 is a fixed 6.8 V device and cannot substitute for a 5.1 V Zener without circuit redesign. Voltage mismatch would cause incorrect biasing or reference levels, potentially leading to ADC saturation or op-amp rail-to-rail clipping.
