Product details
Overview
HZ3C3JTA-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 (min 6.1 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 - deployed in reference voltage sources and stabilized power supplies.
For engineers reviewing the HZ3C3JTA-E datasheet, HZ3C3JTA-E pinout, HZ3C3JTA-E application, or HZ3C3JTA-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 controlled 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 conditions (0.5–1 mA).
The HZ3C3JTA-E exhibits a zener voltage temperature coefficient near zero (≈0 mV/°C at ~6.2 V), confirmed by Figure 2 of REJ03G0182-0300, and maintains low leakage (<1 μA at VR = 2.0 V), supporting high-impedance sensing and low-power bias networks.
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 point with ±0.3 V tolerance for calibration-critical circuits. |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage shift under load transients in feedback loops. |
| 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 including motor control and power supply front-ends. |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - preserves accuracy in high-impedance divider networks and battery-powered sensor references. |
| Package | DO-35 (JEITA GRZZ0002ZB-A) - industry-standard axial leaded glass package with orange body and navy-blue cathode band. |
Pinout & Package
Package: DO-35 glass axial-leaded package per JEITA code GRZZ0002ZB-A; body color orange; cathode identified by navy-blue band; mass ≈ 0.13 g; dimensions per Page 5: φD = 2.0 mm (nom), L = 26.0 mm (min), E = 4.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal where zener breakdown occurs; polarity critical for correct biasing. |
| 2 (non-banded end) | Anode | Connected to circuit ground or lower-potential rail; completes current path during regulation; must be held ≤ VZ below cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Diode noise level reduced to 1/3–1/10 of standard HZ series - directly improves SNR in precision ADC references and audio bias networks. |
| Tight zener voltage tolerance | ±0.3 V over 6.1–6.4 V range at 0.5 mA - eliminates need for post-assembly trimming in factory-calibrated instrumentation. |
| Stable temperature coefficient | ≈0 mV/°C near 6.2 V (per Fig.2) - minimizes drift-induced error in temperature-varying environments without external compensation. |
| Low leakage & high impedance compatibility | <1 μA reverse current at 2.0 V - enables direct interface with CMOS input stages and high-R bias dividers without loading error. |
Applications
| High-Precision Reference Source | Low-Noise Analog Power Supply |

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 |
|---|---|---|---|
| 1N4735A | Zener voltage 6.2 V ±5% (6.0–6.4 V); rd = 7 Ω @ 41 mA; Pd = 1 W; DO-41 package; higher noise than HZ-L series. | Higher power handling but significantly higher noise - suitable for non-critical power rails, not precision references. | Select only when >400 mW dissipation or DO-41 footprint required; avoid for low-noise analog designs. |
| BZX55C6V2 | Zener voltage 6.2 V ±5%; rd = 10 Ω @ 5 mA; Pd = 500 mW; DO-35 package; no specified low-noise characterization. | Lacks documented noise reduction - verified performance limited to general-purpose regulation, not metrology-grade references. | Acceptable for cost-sensitive industrial controls where 0.01% stability is not required; not recommended for calibration equipment. |
Compared with 1N4735A and BZX55C6V2, the HZ3C3JTA-E delivers superior low-noise performance and tighter voltage tolerance in the same DO-35 footprint, making it the preferred choice for applications demanding <0.01% reference stability and sub-μV/√Hz noise density.

FAQ
What is the exact zener voltage range for HZ3C3JTA-E?
The HZ3C3JTA-E has a guaranteed zener voltage range of 6.1 V minimum to 6.4 V maximum when tested at IZ = 0.5 mA, as specified on Page 2 of REJ03G0182-0300. This 0.3 V tolerance supports high-accuracy applications without post-production trimming. The nominal value is 6.2 V, and the device is part of the HZ3CxL subgroup within the HZ-L Series.
Is HZ3C3JTA-E compatible with standard DO-35 footprints?
Yes, HZ3C3JTA-E uses the DO-35 package (JEITA code GRZZ0002ZB-A) with standardized dimensions: φD = 2.0 mm nominal, L ≥ 26.0 mm, and E = 4.2 mm. Its axial leads and orange body with navy-blue cathode band conform to industry DO-35 mechanical specifications, enabling drop-in replacement in existing layouts designed for DO-35 Zener diodes.
How does the noise performance of HZ3C3JTA-E compare to generic Zener diodes?
HZ3C3JTA-E achieves approximately 1/3 to 1/10 the noise level of standard HZ-series Zeners, as stated in the Features section of REJ03G0182-0300. This low-noise characteristic stems from optimized silicon planar processing and is validated for use in precision analog circuits such as ADC references and low-noise op-amp biasing where broadband voltage noise must be minimized.
What is the maximum allowable reverse current before regulation degrades in HZ3C3JTA-E?
HZ3C3JTA-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 2.0 V, per the Electrical Characteristics table on Page 2. Operation above this voltage in non-breakdown mode risks exceeding leakage limits and introducing measurement uncertainty; proper biasing requires maintaining anode ≤ (cathode − 2.0 V) outside regulation.
Can HZ3C3JTA-E be used in surface-mount assemblies?
No, HZ3C3JTA-E is exclusively offered in the through-hole DO-35 axial package and is not available in SMD variants. It requires manual or wave soldering into plated-through holes. For surface-mount equivalents, designers should evaluate Renesas' HZ-L Series SMD options separately - HZ3C3JTA-E itself is not qualified or rated for reflow or SMT processes.
