Product details
Overview
HZ6B1L-JTA-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 5.5–5.8 V, dynamic resistance of 80 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage sources for data converters and sensor signal conditioning.
For engineers reviewing the HZ6B1L-JTA-E datasheet, HZ6B1L-JTA-E pinout, HZ6B1L-JTA-E application, or HZ6B1L-JTA-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 lower than standard HZ series), DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction, with zener voltage specified at DC test current of 0.5 mA and reverse current limited to 1 μA at VR = 2.0 V. Its low dynamic impedance (80 Ω) and tight VZ tolerance support stable biasing in low-drift amplifier feedback networks.
The HZ6B1L-JTA-E exhibits a negative temperature coefficient near 5.6 V (≈−0.04 %/°C per Fig.2), optimized for minimal drift in room-temperature-stable references. It is rated for 400 mW power dissipation at Ta = 25°C, derating linearly above 25°C per Fig.3's published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5–5.8 V at IZ = 0.5 mA - defines stable reference point for ±0.3 V tolerance in precision biasing |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures minimal output voltage shift under load variation |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts with adequate heatsinking |
| Junction Temperature (Tj) | 175°C max - enables reliable use in high-ambient industrial environments |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees low leakage in high-impedance reference nodes |
| Noise Level | ≈1/3–1/10 of standard HZ series - critical for audio preamps and high-resolution ADC references |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), glass axial body with navy blue cathode band and orange body color; mass ≈0.13 g; dimensions per SC-40 standard (φD = 2.0 mm, E = 4.2 mm, L = 26.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to higher-potential node; reverse-biased operation requires positive voltage applied here relative to anode |
| 2 (Anode) | Reference ground terminal | Serves as circuit common; establishes stable VZ drop between cathode and this node |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | Reduces broadband voltage noise by factor of 3–10 vs. legacy HZ series - essential for sub-16-bit DAC/ADC references |
| Tight zener voltage tolerance | ±0.3 V window at 5.6 V nominal - enables direct replacement without recalibration in existing 5.5 V reference designs |
| Low dynamic impedance | 80 Ω max ensures <1 mV output shift per 10 μA load change - improves PSRR in op-amp reference buffers |
| High thermal endurance | 175°C Tj rating allows operation in sealed enclosures or near power components without derating penalties |

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 |
|---|---|---|---|
| 1N5226BRLG | VZ = 3.3 V, rd = 17 Ω, Pd = 500 mW, DO-35 package | Lower voltage, tighter rd, but higher noise and no documented low-noise optimization | Select only if 3.3 V reference is required and noise is secondary to impedance |
| BZX55-C5V6 | VZ = 5.6 V ±5%, rd = 40 Ω, Pd = 500 mW, DO-35 package | Wider VZ tolerance (±5% = ±0.28 V), higher noise, no low-noise specification | Acceptable for non-critical references where cost is prioritized over drift and noise performance |
Compared with 1N5226BRLG and BZX55-C5V6, the HZ6B1L-JTA-E delivers superior noise performance and tighter VZ control at 5.6 V, making it preferred for metrology-grade references despite marginally higher rd - its −0.04 %/°C TC also outperforms both alternatives in temperature-sensitive designs.

FAQ
What is the zener voltage range of the HZ6B1L-JTA-E?
The HZ6B1L-JTA-E has a zener voltage range of 5.5 V to 5.8 V, measured at a test current of 0.5 mA. This tight ±0.3 V window ensures consistent reference accuracy across production lots and supports calibration-free integration into 5.6 V reference designs. The value is DC-tested per REJ03G0182-0300 Rev.3.00, and the HZ6B1L-JTA-E maintains this specification across its qualified operating temperature range.
Does the HZ6B1L-JTA-E have a documented low-noise characteristic?
Yes, the HZ6B1L-JTA-E is explicitly characterized as a low-noise Zener diode, with noise level approximately 1/3 to 1/10 that of the standard HZ series. This performance is achieved via optimized silicon planar processing and is confirmed in the "Features" section of the official Renesas datasheet REJ03G0182-0300. The HZ6B1L-JTA-E leverages this trait in precision analog signal paths where voltage reference noise directly impacts SNR.
What package type does the HZ6B1L-JTA-E use?
The HZ6B1L-JTA-E uses the DO-35 package (JEITA code GRZZ0002ZB-A), a glass axial leaded package with navy blue cathode band and orange body color. Its SC-40 compliant dimensions are φD = 2.0 mm, E = 4.2 mm, and L = 26.0 mm. This package is industry-standard for through-hole Zener diodes and ensures mechanical and thermal compatibility with legacy board designs using the HZ-L Series.
What is the maximum power dissipation rating for the HZ6B1L-JTA-E?
The HZ6B1L-JTA-E has a maximum power dissipation (Pd) of 400 mW at ambient temperature (Ta) of 25°C. Derating follows the linear curve shown in Figure 3 of REJ03G0182-0300, reaching zero dissipation at ~150°C ambient. This rating allows the HZ6B1L-JTA-E to sustain continuous operation in compact industrial enclosures when properly mounted with adequate PCB copper area.
Is the HZ6B1L-JTA-E suitable for high-temperature environments?
Yes, the HZ6B1L-JTA-E supports operation up to a junction temperature (Tj) of 175°C and storage from −55°C to +175°C. Its silicon planar construction and DO-35 package enable reliable performance in under-hood automotive modules, motor drive control boards, and industrial ovens - provided thermal design respects the Pd derating curve. The HZ6B1L-JTA-E's thermal robustness is validated in Renesas' absolute maximum ratings table.
