Product details
Overview
HZS6B2LTA-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, with a nominal zener voltage of 5.6 V to 5.9 V, dynamic resistance of 80 Ω at 0.5 mA, and maximum power dissipation of 400 mW. It features ultra-low noise-approximately 1/3–1/10 that of the legacy HZ series-and is rated for junction temperatures up to 200°C.
For engineers reviewing the HZS6B2LTA-E datasheet, HZS6B2LTA-E pinout, HZS6B2LTA-E application, or HZS6B2LTA-E equivalent, this device is selected for high-stability biasing in instrumentation amplifiers, low-drift reference supplies, and noise-sensitive sensor signal conditioning where zener impedance and thermal coefficient directly impact DC accuracy and long-term drift.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (±0.3 V), low leakage current (≤1 μA at 2.0 V), and a temperature coefficient of approximately −0.02 %/°C near 5.6 V-enabling stable regulation across industrial ambient ranges. Its planar construction ensures reproducible breakdown characteristics and low parameter drift over time.
The HZS6B2LTA-E is designed for DC-biased operation only (per test note), with specified dynamic resistance measured at IZ = 0.5 mA and verified under steady-state thermal conditions. Its MHD package supports high-speed automatic insertion on 5 mm-pitch PCBs and provides mechanical robustness for reflow-compatible assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V min / 5.9 V max - defines stable regulation point for low-voltage reference designs |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 400 mW - sets maximum continuous DC power handling without derating below 25°C |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - ensures minimal error current in high-impedance bias networks |
| Junction Temperature (Tj) | 200°C - enables reliable operation in thermally constrained enclosures or high-ambient environments |
| Noise Level | ≈1/3–1/10 of HZ series - reduces RMS noise contribution in audio preamps and precision ADC references |
Pinout & Package
The HZS6B2LTA-E is housed in the MHD package (JEITA code GRZZ0002ZC-A), a radial-leaded, epoxy-molded diode case with 2.0 mm diameter body and 26 mm lead length, optimized for 5 mm-pitch automated insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Breakdown voltage reference node | Connected to regulated output or bias rail; polarity must be observed to maintain reverse-bias operation |
| 2 (Anode) | Current return path | Typically tied to ground or negative supply; establishes reference potential for VZ drop |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | Reduces broadband voltage noise by factor of 3–10 vs. HZ-series diodes, critical for sub-mV signal integrity |
| Tight VZ tolerance | ±0.3 V window enables accurate 5.6 V reference without post-calibration trimming |
| Low dynamic impedance | 80 Ω at 0.5 mA improves line/load regulation in low-current reference buffers |
| High thermal stability | Negligible temperature coefficient near zero crossing (~−0.02 %/°C) minimizes drift over −40°C to +125°C |
| Automated assembly compatibility | MHD package meets 5 mm pitch and lead coplanarity specs for high-yield SMT/reflow and through-hole insertion |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 (Diodes Inc.) | Higher dynamic resistance (100 Ω), higher noise, SOT-23 package | Surface-mount only; less suitable for high-power or high-reliability through-hole designs | Preferred when board space is constrained and 400 mW dissipation is not required |
| 1N4734A (ON Semiconductor) | Wider VZ tolerance (±5%), higher rd (10 Ω typical but not guaranteed max), TO-92 package | Limited low-noise performance; not characterized for noise reduction vs. legacy series | Acceptable for general-purpose regulation where noise and tight tolerance are non-critical |
Compared with BZX84-C5V6 and 1N4734A, the HZS6B2LTA-E delivers superior noise suppression, tighter VZ control, and guaranteed max dynamic resistance-making it the preferred choice for metrology-grade references, medical sensor front-ends, and industrial calibration systems requiring long-term DC stability.

FAQ
What is the exact zener voltage range specified for HZS6B2LTA-E?
The HZS6B2LTA-E has a guaranteed zener voltage range of 5.6 V minimum to 5.9 V maximum at IZ = 0.5 mA and Ta = 25°C. This 0.3 V window reflects tight process control for precision reference use, and the value is confirmed per Renesas REJ03G0166-0300 Rev.3.00 specification sheet.
Is HZS6B2LTA-E suitable for surface-mount assembly?
No-HZS6B2LTA-E uses the radial-leaded MHD package (JEITA GRZZ0002ZC-A) designed for through-hole or high-speed automatic insertion on 5 mm-pitch boards. It is not a surface-mount device; no SMD variant exists in the HZS-L Series for this voltage grade.
What is the maximum allowable reverse current before breakdown for HZS6B2LTA-E?
The HZS6B2LTA-E specifies a maximum reverse leakage current of 1 μA at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal error in high-impedance reference networks and supports accurate biasing in FET-input amplifier stages.
Does HZS6B2LTA-E have a specified temperature coefficient?
Yes-per Figure 2 in the Renesas datasheet, the HZS6B2LTA-E exhibits a zener voltage temperature coefficient of approximately −0.02 %/°C near its 5.6–5.9 V operating point, indicating excellent thermal stability for low-drift reference designs across industrial temperature ranges.
Can HZS6B2LTA-E be used in place of standard 5.6 V Zeners like 1N4734A?
Yes, functionally-but HZS6B2LTA-E offers significantly lower noise, tighter VZ tolerance (±0.3 V vs. ±5%), and guaranteed max dynamic resistance (80 Ω). Substitution requires verifying mechanical fit (MHD vs. DO-35/TO-92) and thermal layout, as HZS6B2LTA-E is rated for 400 mW and 200°C junction temperature.
