Product details
Overview
HZ4C3JRE-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage reference and regulation in precision analog circuits, featuring a nominal zener voltage of 6.1 V to 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 high-stability power supply feedback paths and sensor biasing networks.
For engineers reviewing the HZ4C3JRE-E datasheet, HZ4C3JRE-E pinout, HZ4C3JRE-E application, or HZ4C3JRE-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 that of standard HZ series), DO-35 package thermal derating behavior, and temperature coefficient stability across 0–70°C ambient range.
Technical Context
This device operates as a two-terminal shunt voltage regulator with DC-tested zener characteristics, where regulation is achieved by maintaining a stable reverse-biased breakdown voltage across its cathode-anode terminals under controlled test current (IZ = 0.5 mA). Its low dynamic impedance (60 Ω) ensures minimal output voltage variation under load transients.
The HZ4C3JRE-E belongs to the HZ-L Series, distinguished by reduced diode noise and tighter zener voltage distribution versus legacy HZ parts. It uses a silicon planar construction with navy-blue cathode band marking and orange body color, packaged in JEITA-standard DO-35 (GRZZ0002ZB-A) with SC-40 footprint compatibility.
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 regulation threshold for feedback loop design |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets upper limit for continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | 175°C max - enables operation in high-ambient industrial environments with appropriate PCB copper area |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - ensures negligible error current in high-impedance reference nodes |
| Temperature Coefficient | ≈ −0.04 %/°C near 6.25 V - supports predictable drift compensation in temperature-critical references |
Pinout & Package
Package: DO-35 (JEITA GRZZ0002ZB-A / SC-40), glass axial leaded case with navy-blue cathode band and orange body color; dimensions: φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm; mass ≈ 0.13 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-side reference node | Connected to regulated output or op-amp inverting input; carries full zener current during regulation |
| 2 (Anode) | Ground or low-side return | Bias reference point for zener conduction; must be held at lowest potential in shunt configuration |
Key Features
| Feature | Design Value |
|---|---|
| Noise Performance | Diode noise level ~1/3–1/10 that of standard HZ series - directly improves SNR in precision ADC references and low-level signal conditioning |
| Zener Voltage Range | 6.1–6.4 V (HZ4C3 variant) - provides tight tolerance for ±0.3 V error budget in 5 V–6 V system rails |
| Low Dynamic Impedance | 60 Ω max at 0.5 mA - minimizes output voltage shift under varying load currents in shunt regulator topologies |
| Thermal Robustness | 175°C max junction temperature - supports reliable operation in sealed enclosures or high-power-density PCBs without forced cooling |

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 |
|---|---|---|---|
| 1N4734A | Zener voltage 5.6 V ±5%, rd = 9 Ω, Pd = 1 W, DO-41 package | Higher power but wider VZ tolerance and no low-noise specification | Preferred where higher power margin is needed and noise is not critical |
| BZX55C6V2 | Zener voltage 6.2 V ±5%, rd = 100 Ω, Pd = 500 mW, DO-35 package | Same package but higher dynamic resistance and unspecified noise performance | Acceptable for general-purpose regulation where cost is prioritized over precision |
Compared with 1N4734A and BZX55C6V2, the HZ4C3JRE-E delivers superior noise reduction and tighter voltage tolerance in the same DO-35 form factor, making it optimal for metrology-grade references - though its 400 mW rating requires careful thermal layout versus the 1 W 1N4734A.

FAQ
What is the exact zener voltage range specified for HZ4C3JRE-E?
The HZ4C3JRE-E has a guaranteed zener voltage range of 6.1 V minimum to 6.4 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.3 V span reflects the "C3" variant designation within the HZ-L Series and supports designs requiring tighter regulation than standard ±5% Zeners. The value is DC-tested per Renesas specification REJ03G0182-0300.
Is HZ4C3JRE-E suitable for surface-mount assembly?
No, the HZ4C3JRE-E uses a through-hole DO-35 glass axial package with 26 mm lead length and 2.0 mm body diameter, intended for wave soldering or manual insertion. It is not compatible with SMT reflow processes. For surface-mount equivalents, consider Renesas' HZ-L Series SOD-123 variants - but note HZ4C3JRE-E itself is strictly DO-35.
What is the maximum reverse leakage current for HZ4C3JRE-E?
The HZ4C3JRE-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 2.0 V and Ta = 25°C. This low leakage supports high-impedance reference nodes and minimizes error in precision biasing circuits - a key differentiator from generic Zeners with leakage up to 5 μA under identical conditions.
Does HZ4C3JRE-E have a documented temperature coefficient?
Yes - while not explicitly listed per-part in the datasheet table, Figure 2 shows the HZ-L Series exhibits a zener voltage temperature coefficient (γZ) of approximately −0.04 %/°C near 6.25 V. This negative coefficient is typical for 6 V-class Zeners and enables predictable drift modeling in compensated reference designs using the HZ4C3JRE-E.
How does the noise performance of HZ4C3JRE-E compare to standard Zener diodes?
The HZ4C3JRE-E achieves diode noise levels approximately 1/3 to 1/10 that of the legacy HZ series, as confirmed in the "Features" section of REJ03G0182-0300. This low-noise characteristic stems from optimized silicon planar processing and is critical in applications like high-resolution ADC references and low-level sensor signal chains where broadband noise directly impacts effective resolution.
