Product details
Overview
HZ5ALL-J-E from Renesas is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.4 V (min 5.4 V / max 5.7 V), 400 mW power dissipation, 60 Ω dynamic impedance at 0.5 mA, and DO-35 glass package with orange body and navy-blue cathode band. It serves as a stable reference in low-drift power supplies and sensor biasing networks.
For engineers reviewing the HZ5ALL-J-E datasheet, HZ5ALL-J-E pinout, HZ5ALL-J-E application, or HZ5ALL-J-E equivalent, key selection criteria include its low-noise performance (1/3–1/10 that of standard HZ series), tight zener voltage tolerance, temperature coefficient behavior below 0.02 %/°C in this voltage range, and suitability for space-constrained PCB layouts requiring axial-leaded DO-35 components.
Technical Context
This device operates as a two-terminal voltage reference using controlled avalanche breakdown in a silicon planar junction. Its low dynamic resistance (60 Ω) and low leakage current (<1 μA at VR = 2.0 V) enable high regulation accuracy under varying load conditions.
The HZ5ALL-J-E belongs to the HZ-L series optimized for noise-sensitive applications; its zener voltage exhibits minimal temperature drift - typically <0.02 %/°C near 5.5 V - and maintains stable operation from −55°C to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.4 V min / 5.7 V max at IZ = 0.5 mA - defines precise DC reference level for feedback loops |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact thermal environments |
| Reverse Current (IR) | ≤1 μA at VR = 2.0 V - reduces parasitic loading in high-impedance reference nodes |
| Junction Temperature (Tj) | −55°C to +175°C - enables use in industrial and automotive under-hood applications |
| Noise Level | ≈1/3–1/10 of standard HZ series - critical for audio preamps, instrumentation amplifiers, and ADC references |
Pinout & Package
Package: DO-35 glass axial-leaded package (JEITA code GRZZ0002ZB-A), orange body with navy-blue cathode band; mass ≈ 0.13 g; dimensions per SC-40 standard (L ≈ 26 mm, φD ≈ 2.0 mm, φb ≈ 0.5 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-impedance voltage reference node | Connected to regulated output or op-amp inverting input; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference ground return path | Biased through current-limiting resistor to system ground; establishes stable reverse-bias condition |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Diode noise reduced to 10–33% of standard HZ series - directly improves SNR in precision analog front-ends |
| Tight zener voltage tolerance | ±0.15 V window (5.4–5.7 V) at 0.5 mA - eliminates need for post-regulation trimming in many designs |
| Stable temperature coefficient | γZ < 0.02 %/°C near 5.5 V - minimizes drift-induced error in temperature-varying environments |
| Low leakage current | <1 μA at 2.0 V reverse bias - preserves accuracy in high-source-impedance reference divider networks |
| Robust thermal rating | 175°C maximum junction temperature - supports reliability in sealed enclosures or high-ambient settings |
Applications
| Audio Signal Conditioning | Precision Sensor Biasing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5231B (ON Semiconductor) | Zener voltage 5.1 V ±5%, rd = 17 Ω, Pd = 500 mW, higher noise than HZ-L series | Higher power margin but lacks low-noise optimization; suitable where noise < 100 nV/√Hz not required | Select when cost sensitivity outweighs noise performance; verify layout filtering for 50/60 Hz hum rejection |
| BZX55-C5V1 (Vishay) | Zener voltage 5.1 V ±5%, rd = 60 Ω, Pd = 500 mW, no specified low-noise characterization | General-purpose replacement; lacks documented noise reduction and tighter VZ binning of HZ5ALL-J-E | Acceptable for non-critical references; avoid in audio or high-resolution sensor systems requiring sub-μV noise |
Compared with 1N5231B and BZX55-C5V1, the HZ5ALL-J-E delivers superior noise performance and tighter voltage tolerance at the expense of slightly lower power rating (400 mW vs. 500 mW), making it optimal for noise-limited, precision-biased analog subsystems rather than general-purpose regulation.

FAQ
What is the exact zener voltage range for HZ5ALL-J-E?
The HZ5ALL-J-E has a guaranteed zener voltage range of 5.4 V minimum to 5.7 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This tight 0.3 V window reflects its "L"-series binning for precision applications and is confirmed in the REJ03G0182-0300 datasheet on page 2 under Electrical Characteristics.
Does HZ5ALL-J-E have a documented noise specification?
Yes - the HZ5ALL-J-E datasheet states its noise level is approximately 1/3 to 1/10 that of the standard HZ series. While absolute nanovolt values are not tabulated, this comparative metric is validated across the full HZ-L family and applies directly to HZ5ALL-J-E as a member of the HZ6A3L subgroup.
What is the maximum reverse leakage current for HZ5ALL-J-E?
The HZ5ALL-J-E exhibits ≤1 μA reverse leakage current when biased at VR = 2.0 V, as specified in the Electrical Characteristics table on page 2 of REJ03G0182-0300. This low leakage supports high-impedance reference networks without introducing measurable offset error.
Is HZ5ALL-J-E compatible with DO-35 footprint layouts?
Yes - HZ5ALL-J-E uses the standard DO-35 axial glass package (JEITA code GRZZ0002ZB-A) with 26 mm length and 2.0 mm diameter. Its mechanical dimensions match industry-standard DO-35 footprints, enabling direct placement in existing designs using SC-40 compliant land patterns.
What is the temperature coefficient behavior of HZ5ALL-J-E?
At its nominal 5.5 V zener voltage, HZ5ALL-J-E exhibits a temperature coefficient γZ below 0.02 %/°C, as shown in Figure 2 of the datasheet. This low drift rate ensures reference stability across industrial temperature ranges without external compensation circuitry.
