Product details
Overview
HZ6B1L-J-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.5–5.8 V, dynamic resistance of 80 Ω at 0.5 mA, and maximum power dissipation of 400 mW in a DO-35 package. It serves as a stable reference in low-current bias networks, sensor excitation circuits, and noise-sensitive instrumentation.
For engineers reviewing the HZ6B1L-J-E datasheet, HZ6B1L-J-E pinout, HZ6B1L-J-E application, or HZ6B1L-J-E equivalent, key selection criteria include its low diode noise (≈1/3–1/10 that of standard HZ series), tight zener voltage tolerance, low leakage current (<1 μA at VR = 2.0 V), and suitability for stabilized power supply references requiring thermal stability and minimal voltage drift.
Technical Context
The HZ6B1L-J-E operates as a two-terminal voltage reference device using silicon planar junction technology with controlled doping and geometry to minimize flicker (1/f) noise and achieve stable breakdown characteristics. Its zener voltage exhibits a temperature coefficient near zero (~0.02 %/°C) within the 5.5–5.8 V range, enabling stable operation across −55°C to +175°C ambient conditions.
Designed for DC-biased applications, it is characterized with IZ = 0.5 mA test current and specified with maximum reverse current IR ≤ 1 μA at VR = 2.0 V, ensuring high impedance stability in high-gain feedback paths. The device's low dynamic resistance (rd = 80 Ω) supports effective ripple suppression in low-power reference buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5–5.8 V at IZ = 0.5 mA - defines precise DC reference level for analog signal conditioning and ADC/DAC biasing |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures low AC impedance for effective ripple rejection in reference nodes |
| Reverse Current (IR) | ≤1 μA at VR = 2.0 V - guarantees minimal loading error in high-impedance sensing or feedback circuits |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −55°C to +175°C - enables deployment in industrial and automotive under-hood environments |
| Noise Level | ≈1/3–1/10 of standard HZ series - reduces broadband voltage noise in precision op-amp references and sensor front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5221BLT1G | Zener voltage 5.1 V ±5%, rd = 17 Ω, Pd = 225 mW, SOT-23 package | Lower power rating and surface-mount form factor - suitable for space-constrained digital logic rails but not high-stability analog references | Select when PCB real estate is limited and ±5% VZ tolerance is acceptable; avoid in precision sensor biasing. |
| Vishay BZX55-C5V6 | Zener voltage 5.6 V ±5%, rd = 40 Ω, Pd = 500 mW, DO-35 package, no low-noise optimization | Higher power capability but 3× higher noise than HZ6B1L-J-E - adequate for general-purpose regulation but insufficient for audio-grade designs | Choose for cost-sensitive industrial supplies where noise performance is secondary to ruggedness and availability. |
Compared with MMBZ5221BLT1G and BZX55-C5V6, the HZ6B1L-J-E delivers superior noise performance and tighter voltage tolerance in the same DO-35 footprint, making it the preferred choice for analog signal chains demanding metrological-grade stability without increasing layout complexity.

FAQ
What is the exact zener voltage range for HZ6B1L-J-E?
The HZ6B1L-J-E has a guaranteed zener voltage range of 5.5 V to 5.8 V when tested at IZ = 0.5 mA and Ta = 25°C. This narrow ±0.15 V window ensures predictable reference behavior in calibration-critical circuits without post-manufacturing sorting or trimming.
Is HZ6B1L-J-E suitable for use in automotive under-hood applications?
Yes, the HZ6B1L-J-E supports junction temperatures up to +175°C and storage temperatures from −55°C to +175°C. While not AEC-Q200 qualified, its robust thermal specification makes it viable for non-safety-critical under-hood functions such as sensor biasing in engine control modules when derated per Renesas' thermal curves.
How does the noise performance of HZ6B1L-J-E compare to standard Zener diodes?
The HZ6B1L-J-E achieves approximately 1/3 to 1/10 the diode noise level of the legacy HZ series due to optimized silicon planar processing and junction design. This translates to measurable reductions in integrated RMS noise voltage - particularly beneficial in microphone preamps and high-resolution data acquisition front-ends.
What is the maximum reverse current specification for HZ6B1L-J-E?
The HZ6B1L-J-E specifies a maximum reverse current IR of 1 μA at VR = 2.0 V and Ta = 25°C. This ultra-low leakage ensures minimal error contribution in high-impedance reference divider networks and preserves accuracy in battery-operated systems with microamp-level standby budgets.
Can HZ6B1L-J-E be used as a direct replacement for older HZ6B1 diodes?
No - the HZ6B1L-J-E belongs to the enhanced HZ-L series with significantly lower noise and tighter VZ tolerance versus the original HZ6B1. While electrically compatible in most circuits, its improved characteristics may alter noise-sensitive system behavior; validation in the target application is recommended before substitution.
