Product details
Overview
HZ6B1L2TA-E from Renesas is a silicon planar Zener diode engineered 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 where noise suppression is critical.
For engineers reviewing the HZ6B1L2TA-E datasheet, HZ6B1L2TA-E pinout, HZ6B1L2TA-E application, or HZ6B1L2TA-E equivalent, key selection criteria include its 1/3–1/10 lower noise versus standard HZ series, −0.04 to +0.02 %/°C temperature coefficient, and suitability for low-current (<1 mA) stabilized references requiring minimal thermal drift and leakage.
Technical Context
This device operates as a two-terminal shunt regulator using silicon planar junction technology optimized for reduced flicker (1/f) noise. Its zener breakdown mechanism is designed for stable DC regulation at test currents of 0.5 mA, with low leakage (<1 μA at VR = 2.0 V) and tight VZ tolerance across production lots.
The HZ6B1L2TA-E exhibits a negative-to-slightly-positive zener voltage temperature coefficient (γZ) centered near 5.65 V, enabling predictable drift compensation in multi-diode reference strings. Its DO-35 package supports manual or wave soldering with 26 mm lead length and 0.5 mm body diameter, conforming to JEITA GRZZ0002ZB-A standards.
Key Specifications

|---|---|---|---|
| 1N5226B (ON Semiconductor) | VZ = 3.3 V, rd = 25 Ω, Pd = 500 mW, higher noise floor | Lower voltage grade; suited for 3.3 V logic supply regulation, not 5.6 V analog references | Select only when 3.3 V reference and higher power margin are required; not interchangeable with HZ6B1L2TA-E |
| BZX55C5V6 (Vishay) | VZ = 5.6 V ±5%, rd = 40 Ω, no published noise spec, DO-35 package | Looser VZ tolerance and uncharacterized noise performance limit use in metrology-grade designs | Acceptable for cost-sensitive industrial supplies where 5% VZ tolerance and absence of noise data are acceptable |

FAQ
What is the exact zener voltage range specified for HZ6B1L2TA-E?
The HZ6B1L2TA-E has a guaranteed zener voltage range of 5.5 V to 5.8 V when tested at IZ = 0.5 mA and Ta = 25°C. This 0.3 V span reflects production binning for tight regulation tolerance and is documented in the REJ03G0182-0300 datasheet on page 2. The nominal center value is 5.65 V, used for temperature coefficient and dynamic resistance characterization of the HZ6B1L2TA-E.
Does HZ6B1L2TA-E support operation above 100°C ambient temperature?
Yes, the HZ6B1L2TA-E is rated for storage from −55°C to +175°C and has a maximum junction temperature of 175°C. Its power dissipation must be derated linearly above 25°C ambient per the curve in Figure 3 of the datasheet; at 100°C ambient, usable Pd drops to approximately 240 mW. This makes the HZ6B1L2TA-E viable for under-hood automotive modules and enclosed industrial drives where thermal management is constrained.
How does the noise performance of HZ6B1L2TA-E compare to standard Zener diodes?
The HZ6B1L2TA-E achieves approximately 1/3 to 1/10 lower diode noise than conventional HZ-series Zeners due to optimized silicon planar junction processing and low-leakage design. This reduction is measured in the 10 Hz–10 kHz band and directly translates to improved signal-to-noise ratio in applications like microphone preamplifiers and strain-gauge bridges where the HZ6B1L2TA-E serves as the primary bias or reference source.
Is HZ6B1L2TA-E compatible with lead-free reflow soldering processes?
Yes, the DO-35 glass package of the HZ6B1L2TA-E is qualified for lead-free wave and hand soldering per JEDEC J-STD-020. Peak temperatures up to 260°C for ≤10 seconds are supported, matching standard Pb-free reflow profiles. The device's 175°C Tj rating and axial lead geometry ensure mechanical and electrical integrity during assembly, making the HZ6B1L2TA-E suitable for modern RoHS-compliant manufacturing lines.
What is the reverse leakage current specification for HZ6B1L2TA-E?
The HZ6B1L2TA-E specifies a maximum reverse leakage current (IR) of 1 μA when tested at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal current draw in high-impedance reference divider networks and prevents significant error in op-amp-based reference buffers. The value is confirmed in the Electrical Characteristics table on page 2 of the REJ03G0182-0300 datasheet for the HZ6B1L2TA-E.
