Product details
Overview
HZ5C3J-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 6.1 V to 6.4 V, dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage sources and sensor signal conditioning.
For engineers reviewing the HZ5C3J-E datasheet, HZ5C3J-E pinout, HZ5C3J-E application, or HZ5C3J-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance relative to 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 reduced noise level (≈1/3–1/10 of HZ series) stem from optimized doping profile and junction geometry.
It is rated for DC test conditions only, with reverse current limited to 1 μA at VR = 2.0 V, and exhibits a zener voltage temperature coefficient near zero in the 6–7 V range - critical for stable biasing in low-drift amplifiers and ADC references.
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 tight regulation window for 6.25 V nominal reference |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output impedance under varying load current |
| 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 use in high-temperature industrial environments including motor control feedback paths |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees low leakage in high-impedance reference nodes |
| Package | DO-35 (GRZZ0002ZB-A) - industry-standard axial leaded package with orange body and navy blue cathode band |
Pinout & Package
DO-35 glass axial package with 2 mm diameter body, 26 mm overall length, and 0.5 mm lead diameter. Cathode identified by navy blue band; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output node; polarity must be observed to avoid forward conduction |
| 2 (Unbanded End) | Anode | Connected to ground or lower-potential rail; forms reference return path in shunt regulator topology |
Key Features
| Feature | Design Value |
|---|---|
| Noise Performance | Approximately 1/3–1/10 lower noise than standard HZ series - directly improves SNR in precision instrumentation front-ends |
| Zener Voltage Range | 6.1–6.4 V tolerance at 0.5 mA - enables accurate 6.25 V ±2.4% reference without trimming |
| Thermal Stability | Near-zero temperature coefficient in 6–7 V range - minimizes drift over −40°C to +85°C operating ambient |
| Leakage Control | 1 μA max reverse current at 2.0 V - preserves accuracy in high-resistance divider networks and battery-powered sensors |

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%, rd = 7 Ω, Pd = 1 W, DO-41 package | Higher power but wider voltage tolerance and higher noise vs. HZ5C3J-E | Select when higher power margin is required and tighter voltage tolerance is not critical |
| BZX55C6V2 | Zener voltage 6.2 V ±5%, rd = 10 Ω, Pd = 500 mW, DO-35 package | Lower noise than 1N4735A but still 3× higher than HZ5C3J-E; no documented low-noise optimization | Choose for DO-35 compatibility where moderate noise performance suffices |
Compared with 1N4735A and BZX55C6V2, HZ5C3J-E delivers superior voltage accuracy (±0.3 V vs. ±5%), significantly lower noise, and optimized thermal coefficient - making it preferred for metrology-grade references despite lower power rating.

FAQ
What is the exact zener voltage range specified for HZ5C3J-E?
The HZ5C3J-E has a guaranteed zener voltage range of 6.1 V minimum to 6.4 V maximum when tested at 0.5 mA zener current and 25°C ambient temperature. This narrow ±0.15 V window supports high-accuracy reference design without external trimming and is tighter than standard 5% tolerance Zeners like the 1N4735A.
Does HZ5C3J-E support DC-only operation or can it handle AC-coupled signals?
HZ5C3J-E is characterized and tested exclusively under DC conditions per its datasheet (REJ03G0182-0300 Rev.3.00), with all electrical parameters - including dynamic resistance and reverse current - specified for steady-state DC operation. It is not rated for AC signal clamping or high-frequency regulation.
How does the noise performance of HZ5C3J-E compare to standard Zener diodes?
HZ5C3J-E achieves approximately 1/3 to 1/10 the noise level of the legacy HZ series due to proprietary junction processing and planar structure optimization. This reduction directly lowers integrated RMS noise in reference paths, enabling sub-16-bit ENOB preservation in high-resolution data converters where standard Zeners introduce measurable broadband interference.
What is the cathode identification method on the HZ5C3J-E package?
The cathode of HZ5C3J-E is marked by a navy blue band on the orange-colored DO-35 glass body. Pin 1 (cathode) corresponds to the banded end; Pin 2 (anode) is the unbanded lead. This marking aligns with JEITA standard GRZZ0002ZB-A and Renesas' HZ-L Series packaging convention.
Can HZ5C3J-E be used in surface-mount designs?
No - HZ5C3J-E is supplied exclusively in the through-hole DO-35 axial package (JEITA code GRZZ0002ZB-A) and lacks SMD variants. For surface-mount equivalents, engineers should evaluate Renesas' HZ-L Series SOD-123 or SOD-323 packaged devices - but HZ5C3J-E itself requires plated-through-hole mounting with 26 mm lead spacing.
