Product details
Overview
HZ6B1J-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.5 V to 5.8 V at 0.5 mA test current, dynamic resistance of 80 Ω max, and 400 mW power dissipation in DO-35 package. It serves as a stable reference in low-drift power supply feedback paths and sensor bias networks.
For engineers reviewing the HZ6B1J-E datasheet, HZ6B1J-E pinout, HZ6B1J-E application, or HZ6B1J-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance relative to legacy HZ series, thermal coefficient behavior below 7 V, and DO-35 mechanical compatibility with through-hole PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference using controlled avalanche breakdown in a planar-diffused silicon junction. Its low dynamic impedance (80 Ω max) and reduced noise level-approximately one-third to one-tenth that of standard HZ-series diodes-enable high-stability regulation under low-current conditions (IZ = 0.5 mA).
The HZ6B1J-E exhibits a negative temperature coefficient below 5.8 V, with typical γZ ≈ −0.06 %/°C (−3.5 mV/°C), making it suitable for temperature-compensated reference designs when paired with positive-TC components. Absolute maximum ratings include 400 mW power dissipation and 175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5 V min to 5.8 V max at IZ = 0.5 mA - defines tight regulation window for 5.6 V nominal reference applications |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures minimal output voltage shift under load transients |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact through-hole layouts without forced cooling |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in industrial ambient environments up to 125°C with derating |
| Package | DO-35 (JEITA GRZZ0002ZB-A) - industry-standard glass axial package with orange body and navy-blue cathode band |
Pinout & Package
DO-35 glass axial package with 2-terminal configuration: cathode identified by navy-blue band; anode is unmarked end. Body color is orange. Mass: 0.13 g. Dimensions per JEITA SC-40: φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output node; polarity must be observed to maintain reverse-bias operation |
| 2 (Unbanded End) | Anode | Connected to ground or lower-potential rail; completes current path during zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | Noise level ~1/3–1/10 that of HZ-series diodes - critical for audio preamps and precision ADC references |
| Tight VZ tolerance | ±0.3 V at 0.5 mA - reduces need for post-assembly trimming in production calibration |
| Low dynamic impedance | 80 Ω max - maintains regulation accuracy across ±10% load current variation |
| High thermal stability | γZ ≈ −0.06 %/°C - predictable drift behavior enables passive compensation in reference dividers |
Applications
| Audio Signal Conditioning | Precision Sensor Biasing |
|---|---|
Use Scenario: Low-noise DC bias generation for condenser microphone preamplifiers and op-amp input stages. IC Role / Device Role / Timing Role: Voltage reference providing stable 5.6 V rail for JFET source followers and differential pairs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | VZ = 5.6 V ±5%, rd = 9 Ω typ (higher test current), Pd = 1 W, DO-41 package | Higher power rating but wider VZ tolerance and no low-noise specification | Select when higher current capability (>50 mA) is needed and noise is secondary |
| BZX55C5V6 | VZ = 5.6 V ±5%, rd = 40 Ω max at 5 mA, Pd = 500 mW, DO-35 package | Same package but higher test current, looser tolerance, no documented noise reduction | Choose for cost-sensitive industrial controls where ultra-low noise is not required |
Compared with 1N4734A and BZX55C5V6, the HZ6B1J-E delivers superior noise performance and tighter VZ control at low current, making it optimal for battery-powered precision instruments and audio systems where signal integrity dominates over raw power handling.

FAQ
What is the exact zener voltage range for HZ6B1J-E at 0.5 mA?
The HZ6B1J-E has a specified zener voltage range of 5.5 V minimum to 5.8 V maximum when tested at IZ = 0.5 mA, DC. This 0.3 V tolerance reflects tight binning for precision reference use. The value is measured under strictly controlled conditions per REJ03G0182-0300 Rev.3.00, and applies directly to each unit of HZ6B1J-E without extrapolation.
Is HZ6B1J-E pin-compatible with other DO-35 Zener diodes?
Yes, HZ6B1J-E uses the standard DO-35 axial package with cathode identified by a navy-blue band and anode at the unbanded end - identical pinout and mechanical footprint to industry-standard DO-35 Zeners including 1N4734A and BZX55C5V6. This allows direct physical replacement in existing through-hole layouts without board modification.
How does the noise performance of HZ6B1J-E compare to standard Zener diodes?
HZ6B1J-E achieves approximately one-third to one-tenth the noise level of conventional HZ-series Zener diodes, as confirmed in Renesas documentation REJ03G0182-0300. This improvement stems from optimized planar junction processing and low-leakage design, making HZ6B1J-E especially valuable in audio preamplifiers and high-resolution data acquisition front-ends where reference noise directly impacts SNR.
What is the maximum allowable reverse current before breakdown in HZ6B1J-E?
The HZ6B1J-E specifies a maximum reverse current (IR) of 1 μA at VR = 2.0 V, measured at Ta = 25°C. This low leakage ensures minimal error contribution in high-impedance reference divider networks and preserves accuracy in battery-operated systems where standby current matters. The value is guaranteed per the official electrical characteristics table for HZ6B1J-E.
Can HZ6B1J-E be used in temperature-compensated reference circuits?
Yes, HZ6B1J-E exhibits a predictable negative temperature coefficient (γZ ≈ −0.06 %/°C or −3.5 mV/°C near 5.6 V), enabling use in passive compensation schemes - for example, pairing with a forward-biased diode or positive-TC resistor to achieve near-zero net drift. This behavior is documented in Figure 2 of the HZ-L Series datasheet REJ03G0182-0300 for HZ6B1J-E and related variants.
