Product details
Overview
HZ6C2LTA-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 6.0–6.3 V, dynamic resistance of 60 Ω at 0.5 mA, and maximum power dissipation of 400 mW in a DO-35 package. It delivers stable reference performance in stabilized power supplies, sensor signal conditioning, and low-drift instrumentation.
For engineers reviewing the HZ6C2LTA-E datasheet, HZ6C2LTA-E pinout, HZ6C2LTA-E application, or HZ6C2LTA-E equivalent, this device is selected for its verified low noise (≈1/3–1/10 of standard HZ series), tight zener voltage tolerance, and robust thermal stability across industrial ambient temperatures.
Technical Context
This Zener diode employs a silicon planar junction structure with controlled doping and geometry to minimize shot and thermal noise-critical for high-resolution ADC references and low-level amplifier biasing. Its low leakage current (<1 μA at VR = 2.0 V) and low zener impedance support stable regulation under light-load conditions.
The device operates within a junction temperature range of −55°C to +175°C and exhibits a zener voltage temperature coefficient of approximately −0.02 %/°C near 6.2 V, enabling predictable drift compensation in temperature-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0–6.3 V at IZ = 0.5 mA - defines precise DC reference point for feedback loops and voltage clamping |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output impedance and high regulation accuracy under varying load |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Reverse Leakage (IR) | ≤1 μA at VR = 2.0 V - prevents unwanted current draw in high-impedance bias networks |
| Junction Temperature (Tj) | −55°C to +175°C - enables deployment in automotive under-hood, industrial control, and outdoor equipment |
| Noise Level | ≈1/3–1/10 of HZ series - directly reduces RMS noise in reference paths, improving SNR in precision measurement systems |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), glass axial leaded package with orange body and navy-blue cathode band. Dimensions: φD = 2.0 mm, L = 26.0 mm, mass ≈ 0.13 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated positive rail; reverse-biased operation requires cathode at higher potential than anode |
| 2 (Anode) | Reference ground terminal | Tied to circuit common or low-side current-sense node; establishes return path for zener current |
Key Features
| Feature | Design Value |
|---|---|

| Low dynamic impedance | 60 Ω max ensures <0.5% output deviation over ±10% load current variation in shunt regulator configurations |
| High thermal stability | Temperature coefficient ≈ −0.02 %/°C minimizes drift-induced error in wide-temperature-range instrumentation |
| DO-35 mechanical reliability | Proven glass-sealed axial package withstands >1000 thermal cycles and meets JEDEC J-STD-020 moisture sensitivity level 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Nexperia) | 6.2 V nominal, 90 Ω rd, SOT-23 package, 350 mW Pd | SMT-compatible but higher impedance and noise; unsuitable for ultra-low-noise analog references | Select when board space is constrained and noise budget allows ≤3× HZ6C2LTA-E's noise floor |
| 1N4735A (ON Semiconductor) | 6.2 V nominal, 7 Ω rd, DO-41 package, 1 W Pd, higher noise than HZ-L series | Higher power handling but 3–5× higher noise; better for power regulation than precision referencing | Choose only for non-critical voltage clamping where thermal margin outweighs noise sensitivity |
Compared with BZX84-C6V2 and 1N4735A, the HZ6C2LTA-E uniquely balances ultra-low noise, tight voltage tolerance, and industrial-grade thermal performance in a legacy-compatible DO-35 through-hole package-making it optimal for analog signal integrity-critical roles rather than generic regulation.

FAQ
What is the exact zener voltage range specified for HZ6C2LTA-E?
The HZ6C2LTA-E has a guaranteed zener voltage range of 6.0 V to 6.3 V when tested at IZ = 0.5 mA and Ta = 25°C. This narrow 300 mV window ensures consistent reference accuracy across production lots without binning or calibration, making it suitable for applications demanding repeatable voltage thresholds such as overvoltage protection and ADC scaling in HZ6C2LTA-E-based designs.
Does HZ6C2LTA-E meet RoHS compliance requirements?
Yes, HZ6C2LTA-E complies with the EU RoHS Directive and contains no restricted substances above allowable thresholds. Renesas Electronics confirms environmental compatibility per applicable regulations, and the device carries full material declaration documentation available upon request for HZ6C2LTA-E procurement and compliance reporting.
What is the maximum allowable junction temperature for continuous operation of HZ6C2LTA-E?
The HZ6C2LTA-E supports a maximum junction temperature (Tj) of +175°C, enabling reliable operation in high-ambient environments such as engine control units or industrial motor drives. Derating curves in the datasheet define safe power limits above 25°C ambient, ensuring thermal safety margins are maintained throughout the full operating life of the HZ6C2LTA-E.
How does the noise performance of HZ6C2LTA-E compare to standard Zener diodes?
The HZ6C2LTA-E achieves approximately 1/3 to 1/10 the broadband noise level of conventional HZ-series Zeners due to optimized planar junction design and low-leakage processing. This measurable reduction directly lowers RMS noise in reference paths-verified in Renesas' characterization data-and makes HZ6C2LTA-E especially valuable in high-resolution data converters and low-noise amplifier biasing where noise floor dominates system performance.
Is HZ6C2LTA-E available in tape-and-reel packaging for automated assembly?
Yes, HZ6C2LTA-E is supplied in tape-and-reel format compatible with standard axial-component feeders, supporting high-volume SMT line integration despite its DO-35 through-hole package. Reel specifications follow JEDEC standards, and Aetrix Electronics provides full logistics support-including reel quantity, orientation marking, and moisture sensitivity level (MSL 1)-for seamless HZ6C2LTA-E deployment in production environments.
