Product details
Overview
HZ5C1JTA-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring 5.8 V to 6.1 V zener voltage (VZ), 400 mW power dissipation, 60 Ω dynamic impedance (rd), and DO-35 glass package with navy-blue cathode band - used in reference voltage generation for ADCs and sensor signal conditioning.
For engineers reviewing the HZ5C1JTA-E datasheet, HZ5C1JTA-E pinout, HZ5C1JTA-E application, or HZ5C1JTA-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), temperature coefficient (−0.02 %/°C at ~6 V), and thermal stability up to 175 °C junction temperature.
Technical Context
HZ5C1JTA-E employs a silicon planar junction structure with controlled doping to achieve low zener impedance (60 Ω at IZ = 0.5 mA) and reduced flicker noise. Its zener voltage is specified at DC test conditions with 0.5 mA current, ensuring stable reference behavior under low-power biasing.
The device operates within a −55 °C to +175 °C storage range and maintains <1 μA reverse leakage (IR) at VR = 2.0 V, supporting reliable performance in thermally demanding industrial and automotive-adjacent signal chains where low drift and repeatable breakdown are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V min / 6.1 V max at IZ = 0.5 mA - defines tight 300 mV tolerance window for precision reference use. |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients. |
| Power Dissipation (Pd) | 400 mW at Ta = 25 °C - supports operation in compact PCB layouts without forced cooling. |
| Junction Temperature (Tj) | 175 °C max - enables deployment in high-ambient environments such as engine control modules or industrial PLCs. |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - minimizes error current in high-impedance reference nodes. |
| Noise Reduction | 1/3–1/10 of HZ-series noise - directly improves SNR in low-level analog front-ends like medical instrumentation. |
Pinout & Package
Package: DO-35 glass axial package (JEITA code GRZZ0002ZB-A), orange body with navy-blue cathode band, 2.0 mm diameter × 26.0 mm length, 0.13 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated positive rail; polarity must be observed to avoid forward conduction. |
| 2 (Anode) | Reference ground node | Tied to circuit common; forms low-impedance return path for zener current and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Reduces RMS noise amplitude by factor of 3–10 vs. legacy HZ series, critical for 16-bit+ data acquisition systems. |
| Stable temperature coefficient | −0.02 %/°C near 6 V - enables <±0.5 % total drift over −40 °C to +85 °C ambient without trimming. |
| Low dynamic impedance | 60 Ω typical - maintains <10 mV output shift across 10–100 μA load current changes in shunt regulator topologies. |
| High-reliability glass package | DO-35 with hermetic seal - provides long-term parameter stability and moisture resistance in humid industrial enclosures. |

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 |
|---|---|---|---|
| BZX55C6V2 (ON Semiconductor) | VZ = 6.2 V ±5 % (±0.31 V), rd = 100 Ω, Pd = 500 mW, DO-35 | Wider VZ tolerance and higher impedance reduce accuracy in precision references but support higher power margin. | Select when absolute voltage accuracy is secondary to cost and availability; not recommended for sub-0.1 % reference designs. |
| MMSZ5234B (Diodes Inc.) | VZ = 6.2 V ±5 %, rd = 70 Ω, Pd = 350 mW, SOD-123 surface-mount | Surface-mount package enables automated assembly but lacks HZ5C1JTA-E's low-noise optimization and 175 °C Tj. | Choose for space-constrained PCBs where reflow compatibility outweighs ultra-low-noise requirement. |
Compared with BZX55C6V2 and MMSZ5234B, HZ5C1JTA-E delivers tighter VZ tolerance (±0.15 V vs. ±0.31 V), lower dynamic impedance (60 Ω vs. ≥70 Ω), and industry-leading noise reduction - making it uniquely suited for metrology-grade analog references where spectral purity and thermal stability are non-negotiable.

FAQ
What is the exact zener voltage range for HZ5C1JTA-E?
HZ5C1JTA-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 300 mV tolerance window is tighter than standard Zener diodes and supports high-accuracy reference design without post-production trimming. The HZ5C1JTA-E datasheet specifies this range under DC test conditions per REJ03G0182-0300 Rev.3.00.
Does HZ5C1JTA-E support operation above 125 °C ambient temperature?
HZ5C1JTA-E is rated for junction temperatures up to 175 °C and storage from −55 °C to +175 °C, enabling reliable operation in high-ambient environments. While its power derating curve begins at 25 °C, the device maintains functional VZ and rd specifications up to Tj = 175 °C - confirmed in the Absolute Maximum Ratings table of the HZ5C1JTA-E datasheet.
How does the noise performance of HZ5C1JTA-E compare to standard Zener diodes?
HZ5C1JTA-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 packaging. This reduction directly improves signal-to-noise ratio in sensitive analog stages - a verified characteristic documented in the Features section of the HZ5C1JTA-E datasheet (REJ03G0182-0300).
Is HZ5C1JTA-E compatible with lead-free reflow soldering processes?
HZ5C1JTA-E uses a DO-35 glass axial package with tin-plated leads compliant with JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - meaning it is rated for unlimited floor life and withstands standard lead-free reflow profiles (peak 260 °C). The HZ5C1JTA-E package dimensions and material specification (glass body, copper leads) confirm full compatibility per Renesas' published handling guidelines.
What is the reverse leakage current specification for HZ5C1JTA-E?
HZ5C1JTA-E exhibits a maximum reverse leakage current (IR) of 1 μA when tested at VR = 2.0 V and Ta = 25 °C. This low leakage preserves accuracy in high-impedance reference nodes and minimizes error contributions in battery-powered applications - a value explicitly listed in the Electrical Characteristics table of the HZ5C1JTA-E datasheet.
