Product details
Overview
HZ36-1L-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 34.2–35.7 V at 0.5 mA, 300 Ω dynamic impedance, 400 mW power dissipation, and DO-35 glass package with navy-blue cathode band - used in reference supplies for ADCs and sensor signal conditioning.
For engineers reviewing the HZ36-1L-E datasheet, HZ36-1L-E pinout, HZ36-1L-E application, or HZ36-1L-E equivalent, key selection criteria include zener voltage tolerance (±2.2%), temperature coefficient (−0.08 %/°C), low noise performance (1/3–1/10 of standard HZ series), and thermal stability up to 175°C junction temperature.
Technical Context
The HZ36-1L-E operates as a two-terminal shunt regulator with DC-tested zener voltage specification and defined dynamic resistance under 0.5 mA test current. Its low leakage and stable rd support high-precision biasing in low-current analog front-ends.
Designed for low-noise applications, it achieves reduced voltage fluctuation via optimized silicon planar junction structure and tight process control - distinct from general-purpose Zeners by its specified noise reduction ratio and tighter VZ tolerance across the 34.2–35.7 V range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.2–35.7 V at IZ = 0.5 mA - defines stable regulation point for mid-range precision references |
| Dynamic Resistance (rd) | 300 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −55 to +175 °C - enables use in industrial and automotive under-hood environments |
| Temperature Coefficient (γZ) | −0.08 %/°C - provides predictable, linear VZ drift over temperature for calibration-critical designs |

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 |
|---|---|---|---|
| 1N5255B (ON Semiconductor) | Zener voltage 33 V, ±5% tolerance, 350 Ω rd, 500 mW Pd | Higher tolerance and impedance; less suitable for precision references but more robust for general stabilization | Select when cost sensitivity outweighs precision requirements and wider VZ spread is acceptable |
| BZX85C36 (Vishay) | Zener voltage 36 V, ±5% tolerance, 100 Ω rd at 10 mA, 1.3 W Pd, DO-41 package | Higher power rating and lower rd at higher current, but larger footprint and no low-noise specification | Choose for higher-current shunt regulation where board space permits and noise is secondary to power handling |
Compared with 1N5255B and BZX85C36, the HZ36-1L-E delivers superior voltage stability (±2.2% vs. ±5%), verified low-noise performance, and optimized thermal behavior for precision analog use - though at lower power rating and stricter current operating point.

FAQ
What is the exact zener voltage range for HZ36-1L-E?
The HZ36-1L-E has a guaranteed zener voltage range of 34.2 V to 35.7 V when tested at IZ = 0.5 mA and Ta = 25°C. This ±2.2% tolerance is tighter than standard Zener diodes and reflects Renesas' process control for precision reference applications. The HZ36-1L-E datasheet (REJ03G0182-0300) confirms this specification on page 3 under Electrical Characteristics.
Is HZ36-1L-E suitable for low-noise applications?
Yes, the HZ36-1L-E is explicitly designed for low-noise applications: its noise level is approximately 1/3 to 1/10 that of the standard HZ series, as stated in the Features section of the official Renesas datasheet. This performance stems from optimized silicon planar junction fabrication and is validated for use in precision analog circuits such as ADC references and sensor excitation supplies where voltage noise directly impacts measurement fidelity. The HZ36-1L-E achieves this without external filtering.
What package type does HZ36-1L-E use, and what are its mechanical dimensions?
The HZ36-1L-E uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A), with a body diameter of 2.0 mm, overall length of 26.0 mm, and typical mass of 0.13 g. It features an orange body and navy-blue cathode band. Dimensions are fully documented in the Package Dimensions diagram on page 5 of the REJ03G0182-0300 datasheet, confirming compatibility with standard DO-35 footprint and hand-soldering or wave-solder processes.
What is the maximum power dissipation and thermal limit for HZ36-1L-E?
The HZ36-1L-E has a maximum power dissipation (Pd) of 400 mW at Ta = 25°C, with a maximum junction temperature (Tj) of 175°C and storage temperature range of −55°C to +175°C. Derating begins above 25°C ambient per the curve in Figure 3 (Page 4), reaching ~200 mW at 70°C. These ratings allow reliable operation in industrial enclosures without heatsinking, provided PCB copper area and airflow meet basic thermal guidelines outlined in the Renesas application notes for DO-35 devices.
How does the temperature coefficient of HZ36-1L-E compare to other Zener diodes in the same voltage range?
The HZ36-1L-E exhibits a temperature coefficient (γZ) of −0.08 %/°C, as shown in Figure 2 (Page 4) of the datasheet - significantly more stable than generic 36 V Zeners, which often exceed ±0.1 %/°C. This value is confirmed for the full 34.2–35.7 V range and enables predictable, linear VZ drift over temperature, simplifying calibration in wide-temperature-range instruments. The HZ36-1L-E's coefficient is part of Renesas' HZ-L series optimization for precision analog use cases.
