Product details
Overview
HZ6B2JTA from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 5.6 V (min 5.6 V, max 5.9 V), dynamic resistance of 80 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It is used in stabilized power supplies, reference voltage sources, and noise-sensitive instrumentation.
For engineers reviewing the HZ6B2JTA datasheet, HZ6B2JTA pinout, HZ6B2JTA application, or HZ6B2JTA equivalent, key selection criteria include its low-noise performance (1/3–1/10 that of standard HZ series), tight zener voltage tolerance, DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
The HZ6B2JTA operates as a two-terminal shunt regulator with DC-tested zener characteristics, specified at 0.5 mA test current. Its low dynamic resistance (80 Ω) and low leakage support stable voltage reference generation under light-load conditions.
Designed for low-noise applications, it achieves reduced diode noise via optimized silicon planar construction and process control-distinct from general-purpose Zeners. The device exhibits a zener voltage temperature coefficient near zero in the 5.6 V range, minimizing drift in precision biasing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - enables low output impedance and improved load regulation |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - allows reliable operation in high-temperature industrial environments |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - minimizes standby current in battery-powered reference circuits |

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 |
|---|---|---|---|
| BZX55C5V6 (ON Semiconductor) | Zener voltage 5.6 V ±5% (5.32–5.88 V); rd = 40 Ω typical; Pd = 500 mW; DO-35 package | Higher power rating but wider VZ tolerance and no low-noise specification | Select when higher power margin is needed and noise is not critical |
| MMSZ5232B (Vishay) | Zener voltage 5.6 V ±5%; rd = 15 Ω typical; Pd = 350 mW; SOD-123 surface-mount package | Surface-mount form factor and lower rd, but no documented low-noise performance or 175°C Tj | Select for space-constrained PCBs where solder-reflow compatibility is required |
Compared with BZX55C5V6 and MMSZ5232B, the HZ6B2JTA offers uniquely verified low-noise operation and tighter VZ consistency within its variant group, making it preferred for metrology and audio-grade references despite its through-hole packaging.

FAQ
What is the exact zener voltage range for HZ6B2JTA?
The HZ6B2JTA has a guaranteed zener voltage range of 5.6 V minimum to 5.9 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.3 V window reflects tighter binning than standard 5% tolerance Zeners and is confirmed in Renesas document REJ03G0182-0300, page 2.
Does HZ6B2JTA have a documented low-noise specification?
Yes - the HZ6B2JTA is part of the HZ-L Series explicitly characterized for low noise, with diode noise approximately 1/3 to 1/10 that of the legacy HZ series. This performance is achieved through proprietary silicon planar processing and is stated in the Features section of the official Renesas datasheet for HZ6B2JTA.
What package type and dimensions does HZ6B2JTA use?
HZ6B2JTA uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A), with orange body color and navy blue cathode band. Key dimensions: diameter 2.0 mm (nominal), length 26.0 mm (minimum), and lead spacing E = 4.2 mm (nominal), per Renesas package drawing on page 5 of REJ03G0182-0300.
What is the maximum power dissipation and derating behavior of HZ6B2JTA?
HZ6B2JTA has a maximum power dissipation of 400 mW at Ta = 25°C. Derating begins linearly above 25°C, reaching zero dissipation at approximately 150°C ambient, as shown in Figure 3 ("Power Dissipation vs. Ambient Temperature") on page 4 of the Renesas datasheet REJ03G0182-0300.
Is HZ6B2JTA suitable for high-reliability industrial applications?
Yes - HZ6B2JTA is rated for junction temperatures up to 175°C and storage temperatures from −55°C to +175°C. Its DO-35 glass package provides hermetic sealing, and Renesas specifies it for stabilized power supply and instrumentation use, supporting deployment in industrial control, test equipment, and harsh-environment monitoring systems.
