Product details
Overview
HZ6C3JTA-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 6.1–6.4 V at 0.5 mA, dynamic resistance of 60 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in stabilized power supplies and reference voltage generators.
For engineers reviewing the HZ6C3JTA-E datasheet, HZ6C3JTA-E pinout, HZ6C3JTA-E application, or HZ6C3JTA-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 with DC-tested zener characteristics, designed for low-leakage, low-impedance regulation in linear power stages and analog signal conditioning paths. Its 60 Ω dynamic resistance at 0.5 mA and <1 μA reverse current at VR = 2.0 V support stable biasing in low-power instrumentation.
The HZ6C3JTA-E belongs to the HZ-L Series, distinguished by navy-blue cathode band marking and orange body color, and exhibits a zener voltage temperature coefficient of approximately −0.02 %/°C near 6.2 V - enabling predictable drift behavior in ambient-temperature-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1–6.4 V at IZ = 0.5 mA - defines precise regulation point for low-drift reference design |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output impedance under varying load conditions |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports compact PCB layout without forced cooling |
| Reverse Current (IR) | ≤1 μA at VR = 2.0 V - guarantees low standby leakage in battery-sensitive applications |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in high-ambient industrial environments |
| Storage Temperature | −55°C to +175°C - accommodates wide-range environmental qualification per MIL-STD-202 |
Pinout & Package
Package: DO-35 glass axial lead package (JEITA code GRZZ0002ZB-A), 2.0 mm diameter × 26.0 mm length, 0.13 g mass, orange body with navy-blue cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-side terminal for zener breakdown conduction | Connected to regulated positive rail; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Low-side terminal referenced to ground or common | Provides return path for zener current; determines direction of reverse-biased operation |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Noise level ≈1/3–1/10 that of standard HZ series - critical for audio preamps and sensor front-ends |
| Stable voltage regulation | ±0.3 V zener tolerance at 0.5 mA - reduces calibration overhead in precision ADC references |
| Thermal stability | Temperature coefficient ≈−0.02 %/°C near 6.2 V - enables predictable drift compensation in analog designs |
| Robust reliability | 175°C max junction temperature and −55°C min storage rating - suitable for automotive under-hood and industrial control |
Applications
| Instrumentation Reference | Low-Noise Audio Bias |
|---|---|
Use Scenario: Precision voltage reference for 16-bit SAR ADCs in portable data loggers. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference to ADC internal buffer and external op-amp gain stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | Zener voltage 6.2 V ±5%, rd = 9 Ω typical but higher noise; DO-41 package (larger footprint) | Higher power (1 W) but unsuitable for ultra-low-noise analog due to 3× noise density | Prefer when board space allows larger DO-41 and noise is not critical |
| BZX84-C6V2 | Zener voltage 6.2 V ±5%, SOT-23 package, rd = 60 Ω, but rated only 300 mW and Tj = 150°C | Surface-mount compatible but derates faster above 70°C ambient | Choose for automated assembly where thermal margin >25°C is guaranteed |
Compared with 1N4735A and BZX84-C6V2, the HZ6C3JTA-E delivers superior noise performance and extended thermal capability in a standardized through-hole DO-35 package - making it optimal for legacy-compatible, high-stability analog designs where noise and temperature resilience are prioritized over footprint size or power headroom.

FAQ
What is the exact zener voltage range specified for HZ6C3JTA-E?
The HZ6C3JTA-E has a guaranteed zener voltage range of 6.1 V to 6.4 V when tested at IZ = 0.5 mA and Ta = 25°C. This ±0.15 V tolerance reflects tighter regulation than standard Zener diodes and supports high-accuracy reference design without post-manufacturing trimming. The HZ6C3JTA-E achieves this via Renesas' silicon planar process and low-noise HZ-L Series architecture.
Is HZ6C3JTA-E suitable for surface-mount assembly?
No, the HZ6C3JTA-E uses a DO-35 glass axial package with 2.0 mm diameter and 26.0 mm body length - designed exclusively for through-hole mounting. It is not compatible with reflow or wave soldering processes used for SMT. For surface-mount alternatives, consider BZX84-C6V2 or MMBZ5226B, though neither matches the HZ6C3JTA-E's low-noise performance or 175°C junction rating.
What is the maximum reverse current specification for HZ6C3JTA-E?
The HZ6C3JTA-E specifies a maximum reverse current (IR) of 1 μA at VR = 2.0 V and Ta = 25°C. This low leakage supports energy-efficient operation in battery-powered instrumentation and ensures minimal loading on high-impedance reference nodes. The value is measured under DC conditions per REJ03G0182-0300 Rev.3.00.
Does HZ6C3JTA-E have a documented temperature coefficient?
Yes, the HZ6C3JTA-E exhibits a zener voltage temperature coefficient (γZ) of approximately −0.02 %/°C near its nominal 6.2 V operating point, as shown in Figure 2 of the official datasheet. This negative coefficient enables predictable drift compensation in multi-stage analog circuits and confirms suitability for applications requiring stable reference voltage over −40°C to +85°C ambient ranges.
Can HZ6C3JTA-E replace older HZ6C3L diodes in existing designs?
Yes, the HZ6C3JTA-E is a direct functional and mechanical replacement for HZ6C3L - sharing identical DO-35 package, pinout, zener voltage range (6.1–6.4 V), dynamic resistance (60 Ω), and absolute maximum ratings. The "TA-E" suffix denotes Renesas' updated tape-and-reel packaging and quality screening; electrical performance and thermal specs remain fully aligned with the original HZ6C3L designation.
