Product details
Overview
HZ5ALLRE-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 5.4 V (min 5.4 V / max 5.7 V), dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage generators and low-drift sensor signal conditioning.
For engineers reviewing the HZ5ALLRE-E datasheet, HZ5ALLRE-E pinout, HZ5ALLRE-E application, or HZ5ALLRE-E equivalent, this part requires attention to its DO-35 package mechanical constraints, cathode-band polarity marking, low-noise performance versus standard HZ series, and thermal derating above 25°C ambient.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. Its low noise level (≈1/3–1/10 that of standard HZ series) stems from optimized doping profile and passivation, enabling stable DC biasing in high-gain amplifier stages.
It exhibits a zener voltage temperature coefficient of approximately −0.04 %/°C near 5.4 V, with reverse leakage current ≤1 μA at VR = 2.0 V and dynamic impedance measured under DC conditions at IZ = 0.5 mA.
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 tight regulation window for 5 V reference designs |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output impedance variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets PCB trace width and thermal pad requirements |
| Reverse Leakage (IR) | ≤1 μA at VR = 2.0 V - critical for ultra-low-current bias networks |
| Junction Temperature (Tj) | −55°C to +175°C - supports operation in industrial and automotive under-hood environments |
| Noise Performance | ≈1/3–1/10 lower than HZ series - enables use in audio preamps and precision ADC references |
Pinout & Package
Package: DO-35 glass axial leaded package (JEITA code GRZZ0002ZB-A), orange body color, navy blue cathode band marking, mass ≈0.13 g, dimensions per SC-40 standard (φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-impedance reference node | Connected to regulated output; polarity must match schematic symbol to avoid reverse conduction |
| 2 (Anode) | Ground or return path | Serves as current sink terminal; requires low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | Zener voltage 5.1 V (±5%), rd = 60 Ω, Pd = 300 mW, SOT-23 package | Higher voltage tolerance (±5% vs. ±0.3 V), lower power rating, surface-mount only | Select when board space is constrained and ±5% VZ tolerance is acceptable |
| MMSZ4685 | Zener voltage 5.1 V (±5%), rd = 130 Ω, Pd = 500 mW, SOD-123 package | Higher dynamic impedance, wider VZ tolerance, higher power but no low-noise specification | Choose for cost-sensitive industrial supplies where noise is not critical |
Compared with BZX84-C5V1 and MMSZ4685, HZ5ALLRE-E delivers tighter voltage tolerance (±0.15 V), verified low-noise performance, and axial DO-35 through-hole compatibility - making it preferred for metrology-grade references where stability and spectral purity outweigh footprint constraints.

FAQ
What is the exact zener voltage range specified for HZ5ALLRE-E?
HZ5ALLRE-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 0.3 V span reflects its position within the HZ-L Series' "A3L" variant group, designed for tighter regulation than standard HZ diodes.
Is HZ5ALLRE-E compatible with automated through-hole assembly processes?
Yes, HZ5ALLRE-E uses the standard DO-35 axial package (JEITA code GRZZ0002ZB-A) with 2.0 mm diameter and 26 mm length, fully compatible with wave soldering and axial insertion equipment. Lead spacing and body dimensions conform to SC-40 mechanical specifications.
How does the noise performance of HZ5ALLRE-E compare to standard Zener diodes?
HZ5ALLRE-E achieves approximately 1/3 to 1/10 the broadband voltage noise of conventional HZ-series Zeners due to proprietary planar diffusion and passivation. This is confirmed in Renesas document REJ03G0182-0300, enabling use in audio preamplifiers and precision measurement front-ends where noise floor matters.
What is the maximum allowable reverse current before breakdown for HZ5ALLRE-E?
HZ5ALLRE-E specifies a maximum reverse leakage current of 1 μA at VR = 2.0 V and Ta = 25°C. This low IR ensures minimal error in high-impedance bias networks and supports accurate low-current sensing applications.
Does HZ5ALLRE-E meet any automotive qualification standards?
HZ5ALLRE-E is not AEC-Q200 qualified. While its junction temperature rating extends to +175°C and storage range covers −55°C to +175°C, Renesas documentation does not list automotive qualification testing. It is intended for industrial and general-purpose precision analog use.
