Product details
Overview
HZ6C1J-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 6.0 V (min 5.8 V, max 6.1 V), dynamic resistance of 60 Ω at 0.5 mA test current, 400 mW power dissipation, and DO-35 glass package with navy-blue cathode band. It serves as a stable reference in low-drift power supply feedback paths and sensor biasing networks.
For engineers reviewing the HZ6C1J-E datasheet, HZ6C1J-E pinout, HZ6C1J-E application, or HZ6C1J-E equivalent, key selection criteria include its verified 60 Ω zener impedance at 0.5 mA, −0.04 %/°C temperature coefficient near 6 V, low 1 μA reverse leakage at 2.0 V, and suitability for noise-sensitive instrumentation-grade references where HZ-L series noise reduction (1/3–1/10 vs. standard HZ) is critical.
Technical Context
The HZ6C1J-E operates as a two-terminal voltage reference diode with DC-tested zener breakdown characteristics, designed for stable regulation under low-current conditions (IZ = 0.5 mA). Its planar silicon construction ensures repeatable breakdown voltage and low junction capacitance.
It exhibits a negative temperature coefficient of approximately −0.04 %/°C (−0.24 mV/°C) at 6.0 V, placing it in the optimal range for low-drift reference design. The device is rated for 175°C maximum junction temperature and −55°C to +175°C storage range, supporting industrial ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V min to 6.1 V max at IZ = 0.5 mA - defines tight regulation window for 6 V reference applications |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage Current (IR) | 1 μA max at VR = 2.0 V - supports ultra-low quiescent current bias networks |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - enables use in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - allows reliable operation in high-temperature industrial enclosures |
| Zener Temp. Coefficient (γZ) | −0.04 %/°C typical - minimizes drift over temperature in precision analog front-ends |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated output node; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference ground return | Serves as current sink path; requires low-impedance connection to system ground or feedback node |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V2 (ON Semiconductor) | Zener voltage 6.2 V ±5%, rd = 100 Ω @ 5 mA, Pd = 500 mW, DO-35 package | Higher dynamic impedance and wider voltage tolerance; suited for general-purpose regulation, not low-noise designs | Select only when noise performance is non-critical and 6.2 V nominal is acceptable |
| MMSZ5234B (Diodes Inc.) | Zener voltage 6.2 V ±5%, rd = 70 Ω @ 20 mA, SOD-123 surface-mount package, Pd = 350 mW | Surface-mount form factor and higher test current; lacks HZ-L series noise reduction and 0.5 mA low-current optimization | Prefer for space-constrained PCBs where reflow compatibility outweighs ultra-low-noise requirement |
Compared with BZX55C6V2 and MMSZ5234B, the HZ6C1J-E delivers superior low-noise performance and tighter low-current regulation (0.5 mA), making it uniquely suitable for precision analog reference roles where voltage stability under light load and minimal thermal drift are mandatory.

FAQ
What is the exact zener voltage range for HZ6C1J-E at 0.5 mA test current?
The HZ6C1J-E has a guaranteed zener voltage range of 5.8 V minimum to 6.1 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.3 V total spread reflects Renesas' tight binning for the "C1" variant within the HZ-L family, ensuring predictable behavior in precision reference designs where 6.0 V nominal is required.
Does HZ6C1J-E support operation above 100°C ambient temperature?
Yes, the HZ6C1J-E is rated for storage from −55°C to +175°C and has a maximum junction temperature of 175°C. When mounted on standard FR-4 PCB with typical DO-35 thermal relief, it supports continuous operation up to approximately 125°C ambient at ≤200 mW dissipation, making it suitable for enclosed industrial control cabinets without active cooling.
How does the noise performance of HZ6C1J-E compare to standard Zener diodes?
The HZ6C1J-E achieves approximately 1/3 to 1/10 the noise level of conventional HZ-series Zeners due to optimized planar junction processing and low-impedance structure. This reduction is measurable in spectral density (nV/√Hz) and directly improves signal integrity in high-resolution data acquisition systems using the HZ6C1J-E as an ADC reference or op-amp bias source.
Is HZ6C1J-E compatible with lead-free reflow soldering processes?
Yes, the DO-35 glass package of HZ6C1J-E is qualified for standard lead-free reflow profiles (peak temperature ≤260°C, 60-second duration above 217°C). The device's glass-to-metal seal and internal construction maintain parameter stability after JEDEC J-STD-020-compliant thermal cycling, confirming robustness in modern SMT assembly lines handling the HZ6C1J-E.
What is the reverse leakage current specification for HZ6C1J-E at 2.0 V?
The HZ6C1J-E specifies a maximum reverse leakage current (IR) of 1 μA when measured at VR = 2.0 V and Ta = 25°C. This ultra-low leakage enables use in high-impedance bias networks-such as thermistor dividers or photodiode transimpedance amplifier references-without introducing measurable error into the HZ6C1J-E-regulated node.
