Product details
Overview
HZ2C2JRE-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 6.3 V (min 6.0 V, max 6.4 V), dynamic resistance of 60 Ω at 0.5 mA test current, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It is used in stabilized power supplies, reference voltage sources, and noise-sensitive instrumentation.
For engineers reviewing the HZ2C2JRE-E datasheet, HZ2C2JRE-E pinout, HZ2C2JRE-E application, or HZ2C2JRE-E equivalent, key selection criteria include zener voltage tolerance (±0.2 V), low noise performance (1/3–1/10 lower than standard HZ series), DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
The HZ2C2JRE-E belongs to the HZ-L Series, optimized for low-noise operation via refined silicon planar processing that reduces diode noise by a factor of 3–10 versus legacy HZ devices. Its zener voltage is specified at DC test conditions with IZ = 0.5 mA, and it exhibits a temperature coefficient of approximately −0.04 %/°C near 6.3 V, confirmed by Figure 2 in REJ03G0182-0300.
Designed for stable DC reference applications, the device maintains low zener impedance (60 Ω) and low leakage current (<1 μA at VR = 2.0 V), enabling high-accuracy regulation in low-power analog front-ends and sensor biasing circuits where signal integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V min / 6.4 V max at IZ = 0.5 mA - defines tight 6.3 V nominal regulation point with ±0.2 V tolerance for precision references. |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients in regulated supplies. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling. |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees low quiescent current draw in battery-powered or high-impedance bias networks. |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in industrial environments with elevated ambient temperatures. |
| Storage Temperature | −55°C to +175°C - ensures long-term stability during assembly, storage, and field deployment across harsh conditions. |
Pinout & Package

| 2 (Anode) | Reference ground return | Typically tied to system ground or common reference plane; forms low-impedance path for zener current sink. |
Key Features
| Feature | Design Value |
|---|---|
| Noise reduction vs. HZ series | Diode noise reduced to 1/3–1/10 - directly improves SNR in audio preamps and precision ADC reference stages. |
| Zener voltage range coverage | 6.0–6.4 V window - enables fine-tuned selection within 6.3 V nominal for matched reference pairs or calibration trimming. |
| Low zener impedance | 60 Ω max at 0.5 mA - minimizes AC ripple coupling and enhances regulation accuracy under varying load conditions. |
| Thermal stability | Temperature coefficient ≈ −0.04 %/°C - predictable drift behavior simplifies compensation in wide-temperature-range instruments. |

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 window), 90 Ω dynamic resistance at 5 mA, SOT-23 package. | Higher voltage tolerance and impedance reduce accuracy in precision references; surface-mount form eases automated assembly but limits high-temp reliability. | Select when cost-sensitive, space-constrained designs prioritize footprint over noise and regulation tightness. |
| 1N5234B (ON Semiconductor) | 6.2 V nominal, ±5% tolerance (0.31 V window), 17 Ω dynamic resistance at 20 mA, DO-35 package, higher power (500 mW). | Lower rd benefits high-current regulation but higher noise level compromises low-signal integrity applications. | Prefer for general-purpose stabilization where noise is secondary to current-handling capability and legacy DO-35 compatibility. |
Compared with BZX84-C6V2 and 1N5234B, the HZ2C2JRE-E delivers superior voltage accuracy (±0.2 V vs. ±0.31 V), lower noise, and tighter dynamic resistance control at low test current-making it optimal for precision analog systems where reference stability dominates over raw power handling or assembly cost.

FAQ
What is the exact zener voltage range for HZ2C2JRE-E?
The HZ2C2JRE-E has a guaranteed zener voltage range of 6.0 V minimum to 6.4 V maximum when tested at IZ = 0.5 mA and Ta = 25°C, per REJ03G0182-0300 Rev.3.00 page 2. This 6.3 V nominal rating with ±0.2 V tolerance supports high-accuracy voltage referencing in analog circuits where tight regulation is required. The HZ2C2JRE-E achieves this specification through Renesas' silicon planar process optimization for the HZ-L Series.
Is HZ2C2JRE-E compatible with standard DO-35 footprints?
Yes, the HZ2C2JRE-E uses the DO-35 package (JEITA code GRZZ0002ZB-A) with standardized dimensions: body diameter φD = 2.0 mm, lead spacing E = 4.2 mm, and overall length L = 26.0 mm. Its orange body and navy blue cathode band align with JEDEC DO-35 mechanical specifications, ensuring drop-in compatibility with existing DO-35 sockets and PCB land patterns designed for axial-leaded Zener diodes.
How does the noise performance of HZ2C2JRE-E compare to standard Zener diodes?
The HZ2C2JRE-E delivers approximately 1/3 to 1/10 the diode noise level of the legacy HZ series, as stated in the "Features" section of REJ03G0182-0300. This improvement stems from Renesas' refined silicon planar processing and is verified under identical test conditions. In practice, this translates to measurable SNR gains in low-level analog signal paths-such as microphone preamps or sensor front-ends-where the HZ2C2JRE-E replaces generic Zeners like 1N5234B.
What is the maximum reverse current specification for HZ2C2JRE-E?
The HZ2C2JRE-E specifies a maximum reverse current (IR) of 1 μA at VR = 2.0 V and Ta = 25°C, per the Electrical Characteristics table on page 2 of REJ03G0182-0300. This low leakage supports high-impedance bias networks and battery-operated systems where standby current must remain below nanoampere thresholds. The value is measured under DC conditions and reflects the device's optimized junction characteristics in the HZ-L Series.
Can HZ2C2JRE-E operate reliably at elevated ambient temperatures?
Yes, the HZ2C2JRE-E is rated for storage from −55°C to +175°C and has a maximum junction temperature of 175°C. Its power derating curve (Figure 3, page 4) shows usable dissipation down to ~200 mW at 70°C ambient, supporting deployment in industrial enclosures or under-hood automotive modules. The HZ2C2JRE-E's thermal robustness is inherent to its DO-35 glass package and silicon planar construction, validated per Renesas' qualification standards.
