Product details
Overview
HZ6B1L-JTE-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 5.5–5.8 V, 400 mW power dissipation, 80 Ω dynamic resistance at 0.5 mA, and DO-35 glass package. It serves as a stable reference in low-drift power supplies and sensor biasing networks.
For engineers reviewing the HZ6B1L-JTE-E datasheet, HZ6B1L-JTE-E pinout, HZ6B1L-JTE-E application, or HZ6B1L-JTE-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), junction temperature rating (175°C), and DO-35 mechanical compatibility in space-constrained PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. Its low dynamic impedance (80 Ω @ 0.5 mA) and tight zener voltage tolerance (5.5–5.8 V) enable high regulation accuracy under varying load conditions.
The HZ6B1L-JTE-E exhibits a zener voltage temperature coefficient of approximately −0.04 %/°C (−2.2 mV/°C) near 5.6 V, confirmed by Figure 2 of REJ03G0182-0300, and maintains stable operation up to 175°C junction temperature with −55°C to +175°C storage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5–5.8 V at IZ = 0.5 mA - defines precise DC reference level for feedback loops and analog comparators |
| Dynamic Resistance (rd) | 80 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 continuous operation in compact thermal environments without forced cooling |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees negligible leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 175°C maximum - enables reliable use in industrial and automotive under-hood applications |
| Noise Level | ≈1/3–1/10 of HZ-series diodes - reduces RMS noise contribution in audio preamps and ADC reference stages |
Pinout & Package
Package: DO-35 glass axial package (JEITA code GRZZ0002ZB-A), orange body with navy blue cathode band; dimensions per Page 5: φD = 2.0 mm, L = 26.0 mm, E = 4.2 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 | Typically tied to circuit common; establishes return path for zener current and defines reference node |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener structure | Reduces broadband voltage noise by factor of 3–10 vs. legacy HZ series, critical for high-SNR signal chains |
| Tight zener voltage tolerance | ±0.3 V window (5.5–5.8 V) enables accurate 5.6 V reference without external trimming |
| Low dynamic impedance | 80 Ω max ensures <1 mV output shift per 12.5 μA load change - suitable for micro-power sensor interfaces |
| High thermal stability | −0.04 %/°C tempco minimizes drift over −40°C to +85°C ambient - supports uncalibrated industrial sensors |
| Robust reliability | 175°C max junction temperature and −55°C min storage rating support extended-life deployments in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5226BRLG | Zener voltage 3.3 V (fixed), 100 Ω rd, 500 mW Pd, DO-35 package | Not suitable for 5.6 V reference; requires series stacking or regulator IC for same voltage | Select only if lower voltage reference and higher power margin are acceptable trade-offs |
| BZX55C5V6 | Zener voltage 5.6 V (nominal), ±5% tolerance (±0.28 V), 90 Ω rd, 500 mW Pd, DO-35 | Looser voltage tolerance and higher noise than HZ6B1L-JTE-E; lacks documented low-noise optimization | Acceptable for cost-sensitive non-precision applications where 0.3 V tolerance and noise floor are not critical |
Compared with 1N5226BRLG and BZX55C5V6, the HZ6B1L-JTE-E delivers tighter voltage control (±0.3 V vs. ±0.28 V or fixed 3.3 V), lower dynamic impedance (80 Ω vs. 90–100 Ω), and verified low-noise performance - making it preferable for metrology-grade references and audio biasing where spectral purity matters.

FAQ
What is the exact zener voltage range specified for HZ6B1L-JTE-E?
The HZ6B1L-JTE-E has a guaranteed zener voltage range of 5.5 V to 5.8 V when tested at IZ = 0.5 mA, as stated in the Electrical Characteristics table on Page 2 of REJ03G0182-0300. This ±0.3 V window reflects its role as a precision 5.6 V reference diode, distinct from broader-tolerance alternatives like BZX55C5V6.
Does HZ6B1L-JTE-E have a documented low-noise characteristic compared to standard Zener diodes?
Yes, the HZ6B1L-JTE-E datasheet explicitly states its noise level is approximately 1/3 to 1/10 that of the standard HZ series. This low-noise performance is a defining feature of the HZ-L Series and is validated in the Features section of REJ03G0182-0300 - making HZ6B1L-JTE-E suitable for audio biasing and high-SNR instrumentation where noise contributes directly to system error.
What is the maximum power dissipation and thermal rating of HZ6B1L-JTE-E?
HZ6B1L-JTE-E has a maximum power dissipation of 400 mW at Ta = 25°C and a maximum junction temperature of 175°C, with storage temperature rated from −55°C to +175°C. These ratings are listed in the Absolute Maximum Ratings table on Page 2 and confirm suitability for industrial environments where sustained thermal stress occurs.
Is the HZ6B1L-JTE-E packaged in DO-35, and what are its mechanical dimensions?
Yes, HZ6B1L-JTE-E uses the DO-35 axial glass package (RENESAS code GRZZ0002ZB-A, JEITA code SC-40). Per Page 5 of the datasheet: body diameter φD = 2.0 mm (nominal), length L = 26.0 mm (min), and lead spacing E = 4.2 mm. The orange body with navy blue cathode band provides visual polarity identification.
How does the temperature coefficient of HZ6B1L-JTE-E affect its performance in wide-temperature applications?
HZ6B1L-JTE-E exhibits a zener voltage temperature coefficient of approximately −0.04 %/°C (−2.2 mV/°C) near 5.6 V, as shown in Figure 2 of REJ03G0182-0300. Over a −40°C to +85°C ambient range, this results in ≤ ±0.34% total drift - enabling use in uncalibrated industrial sensors and embedded controllers without external compensation.
