Product details
Overview
HZ3C3JRE-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 6.4 V, dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating of 175°C - deployed in reference voltage sources and low-drift sensor signal conditioning.
For engineers reviewing the HZ3C3JRE-E datasheet, HZ3C3JRE-E pinout, HZ3C3JRE-E application, or HZ3C3JRE-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. Its low dynamic impedance (60 Ω) and tight zener voltage tolerance (6.1–6.4 V) enable stable regulation under low-current bias (0.5–1 mA), with minimal temperature-induced drift (γZ ≈ −0.02 %/°C near 6.4 V).
The HZ3C3JRE-E exhibits ultra-low noise spectral density due to optimized junction geometry and passivation, making it suitable for high-resolution ADC references and low-phase-noise oscillator biasing where conventional Zeners introduce measurable broadband interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1 V min / 6.4 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 max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - enables reliable use in high-ambient industrial environments |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - minimizes error current in high-impedance reference nodes |
| Zener Voltage Tempco (γZ) | ≈ −0.02 %/°C near 6.4 V - provides predictable, low-drift behavior over temperature |
Pinout & Package
Package: DO-35 glass axial package (JEITA code GRZZ0002ZB-A), orange body with navy-blue cathode band; total mass 0.13 g; lead spacing 26 mm; diameter 2.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Negative terminal of reverse-biased junction | Connected to regulated output node; polarity critical for correct biasing |
| 2 (Anode) | Positive terminal of reverse-biased junction | Typically grounded or connected to lower-potential rail in shunt regulator topology |
Key Features
| Feature | Design Value |
|---|---|
| Noise performance | Approximately 1/3–1/10 lower than standard HZ-series Zeners - reduces RMS noise in precision reference paths |
| Zener impedance | 60 Ω max at 0.5 mA - improves line and load regulation in low-current applications |
| Voltage tolerance | ±0.3 V at 6.4 V nominal - enables tighter system-level voltage accuracy without trimming |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Nexperia) | 6.2 V nominal, ±5% tolerance (±0.31 V), 90 Ω rd, 300 mW Pd, SOT-23 package | SMT-compatible but higher impedance and looser tolerance; unsuitable for <10 ppm drift-critical designs | Prefer for space-constrained PCBs where moderate noise and drift are acceptable |
| 1N5233B (ON Semiconductor) | 6.2 V nominal, ±5% tolerance (±0.31 V), 17 Ω rd, 500 mW Pd, DO-35 package | Lower impedance but higher noise and no documented low-noise optimization; wider tempco (±0.05 %/°C) | Select when higher power handling is required and noise is secondary to regulation stiffness |
Compared with BZX84-C6V2 and 1N5233B, the HZ3C3JRE-E delivers superior noise performance and tighter voltage tolerance in the same DO-35 footprint, making it optimal for metrology-grade references where spectral purity and long-term stability outweigh cost or power-density considerations.

FAQ
What is the zener voltage specification for HZ3C3JRE-E?
The HZ3C3JRE-E has a zener voltage range of 6.1 V minimum to 6.4 V maximum, tested at 0.5 mA zener current. This tight 0.3 V tolerance supports high-accuracy voltage referencing without external trimming. The value is guaranteed per Renesas datasheet REJ03G0182-0300 Rev.3.00 and applies to each unit within its specified operating conditions.
Is HZ3C3JRE-E suitable for surface-mount assembly?
No, the HZ3C3JRE-E uses a DO-35 axial glass package with 26 mm lead spacing and is designed for through-hole mounting only. It is not compatible with reflow or wave soldering processes intended for SMT components. For SMT alternatives, consider the BZX84-C6V2, though it lacks the low-noise optimization of the HZ3C3JRE-E.
What is the maximum power dissipation rating for HZ3C3JRE-E?
The HZ3C3JRE-E has a maximum power dissipation of 400 mW at ambient temperature (Ta) = 25°C. Derating is required above 25°C per the published curve in Figure 3 of the datasheet, reaching 0 mW at approximately 150°C ambient. This rating ensures safe operation in compact enclosures with passive cooling.
Does HZ3C3JRE-E have a specified noise performance metric?
Yes - the HZ-L Series, including HZ3C3JRE-E, is explicitly characterized for low noise: its noise level is approximately 1/3 to 1/10 that of the standard HZ series. While no quantitative nV/√Hz value is provided, this comparative specification confirms its suitability for applications sensitive to broadband voltage noise, such as high-resolution data acquisition.
What is the cathode identification method on HZ3C3JRE-E?
The cathode of the HZ3C3JRE-E is marked by a navy-blue band on the orange glass body, consistent with JEDEC DO-35 polarity convention. Pin 1 (cathode) is the banded end; Pin 2 (anode) is the unmarked end. This marking is visible before and after board assembly and aligns with Renesas' package drawing in REJ03G0182-0300.
