Product details
Overview
BZX84J-B6V8,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 6.66 V to 6.94 V nominal Zener voltage at 5 mA test current, 80 Ω differential resistance, and 550 mW total power dissipation - used for precision low-power voltage reference and overvoltage clamping in automotive sensor signal conditioning circuits.
For engineers reviewing the BZX84J-B6V8,115 datasheet, BZX84J-B6V8,115 pinout, BZX84J-B6V8,115 application, or BZX84J-B6V8,115 equivalent, key selection criteria include Zener voltage tolerance, pulse power handling (40 W non-repetitive), AEC-Q101 qualification, thermal resistance (230 K/W junction-to-ambient), and SC-90 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across 5 mA to 20 mA Zener test currents, exhibiting a positive temperature coefficient of +1.2 mV/K to +4.5 mV/K depending on operating current - enabling stable reference performance over -55 °C to +150 °C ambient range.
Its low 80 Ω differential resistance ensures minimal voltage deviation under load variation, while AEC-Q101 qualification confirms robustness against mechanical shock, temperature cycling, and humidity exposure required for automotive-grade signal path protection and biasing functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.66 V to 6.94 V at IZ = 5 mA - defines precise clamping threshold for 6.8 V nominal rail protection |
| Tolerance | ±2 % - enables tighter system-level voltage margin control vs. ±5 % variants |
| Differential Resistance (rdiff) | 80 Ω - limits output voltage shift to ≤80 mV per 1 mA load change near regulation point |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - supports transient surge suppression in CAN/LIN bus interface protection |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in under-hood automotive environments without derating below 125 °C ambient |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test qualification standard for discrete semiconductors |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2-terminal, ultra-small outline (2.7 mm × 1.6 mm × 0.95 mm), flat lead, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for voltage reference function |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 80 Ω at IZ = 5 mA - maintains regulation accuracy under varying load current in feedback networks |
| AEC-Q101 qualification | Validated for automotive use - eliminates need for additional reliability screening in Tier-1 ECU designs |
| Small SOD323F footprint | 2.7 mm × 1.6 mm body - enables placement adjacent to IC pins for local rail decoupling and ESD clamping |
| Wide operating temperature | -55 °C to +150 °C - supports engine control, transmission, and ADAS modules without thermal derating |
| Precision ±2 % tolerance | 6.66 V–6.94 V range - reduces calibration overhead in analog front-end voltage monitoring circuits |
Applications
| Automotive Sensor Biasing | Industrial Analog Input Protection |
|---|---|
Use Scenario: Providing stable 6.8 V reference for Hall-effect position sensor ICs in electric power steering modules. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, setting bias point for sensor amplifier stage. Use Value: ±2 % tolerance ensures sensor output linearity remains within 0.5 % full-scale error across temperature. |
Use Scenario: Clamping 0–10 V analog input lines in PLC analog input modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Shunt protector limiting input voltage to 6.94 V peak during 1 kV EFT bursts. Use Value: 40 W non-repetitive pulse rating absorbs 100 μs surges without degradation, preserving ADC integrity. |
| Automotive LIN Bus Interface | Medical Instrument Reference |

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-C6V8,115 | ±5 % tolerance (6.4 V–7.2 V), higher rdiff (215 Ω), same package and PZSM | Acceptable where system-level calibration compensates for wider voltage spread | Select when cost sensitivity outweighs need for tight regulation in non-critical rails |
| MMSZ4687T1G | ±5 % tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW Ptot, 30 W PZSM | Larger footprint limits routing density; lower pulse rating reduces surge resilience | Choose only if legacy SOD-123 layout reuse is mandatory and surge immunity is secondary |
Compared with BZX84J-B6V8,115, the ±2 % BZX84-C6V8,115 offers lower cost but sacrifices 0.26 V regulation window tightness and 2.7× higher dynamic impedance; MMSZ4687T1G trades SC-90 miniaturization for reduced thermal performance and surge capability - making the BZX84J-B6V8,115 optimal for space-constrained, high-reliability automotive voltage references.

FAQ
What is the maximum continuous forward current for BZX84J-B6V8,115?
The absolute maximum forward current is 250 mA per limiting values table. However, sustained forward conduction is not intended in Zener regulator applications - the device operates in reverse breakdown, and forward voltage is specified only for characterization (1.1 V at 100 mA pulsed).
Does BZX84J-B6V8,115 require a series resistor in typical Zener regulation circuits?
Yes - a current-limiting resistor is mandatory to set the Zener test current (5 mA typical) and prevent thermal runaway. For 12 V supply and 6.8 V output, a 1.0 kΩ ±1 % resistor delivers 5.2 mA, keeping power dissipation within 550 mW rating at 25 °C ambient.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
At 5 mA, BZX84J-B6V8 exhibits +1.2 mV/K to +4.5 mV/K coefficient - resulting in +189 mV to +709 mV drift from -40 °C to +125 °C. System-level compensation or use with temperature-stable op-amps mitigates this in precision references.
Can BZX84J-B6V8,115 be used in parallel for higher power handling?
No - Zener diodes must not be paralleled due to mismatched breakdown voltages causing current hogging. For >550 mW dissipation, use a single higher-rated Zener or active regulation with a pass transistor; thermal coupling between devices does not ensure balanced sharing.
