Product details
Overview
HZS6B1LTD-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog and stabilized power supply circuits, with a nominal zener voltage of 5.5 V to 5.8 V, dynamic resistance of 80 Ω at 0.5 mA, and maximum power dissipation of 400 mW in the MHD package.
For engineers reviewing the HZS6B1LTD-E datasheet, HZS6B1LTD-E pinout, HZS6B1LTD-E application, or HZS6B1LTD-E equivalent, this device is selected for noise-sensitive reference design, low-drift biasing, and compact DC-DC feedback paths where leakage current ≤1 μA and thermal stability across −55°C to +175°C are critical.
Technical Context
The HZS6B1LTD-E operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction, achieving low noise via optimized doping profile and geometry - confirmed by its 1/3–1/10 lower noise level versus legacy HZ-series diodes. Its zener voltage temperature coefficient is minimized near 5.6 V, supporting stable operation without external compensation in ambient ranges up to +125°C.
Designed for high-speed automatic insertion on 5 mm-pitch PCBs, the device uses a single-anode/single-cathode configuration in the MHD package (JEITA GRZZ0002ZC-A), with cathode band marking and lead-free plating compliant with RoHS Directive requirements per Renesas environmental specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5 V min / 5.8 V max at IZ = 0.5 mA - defines tight regulation window for ±3% tolerance reference applications |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures minimal output impedance variation under load transients |
| Reverse Leakage Current (IR) | 1 μA max at VR = 2.0 V - enables ultra-low standby current in battery-backed or energy-efficient systems |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact SMT layouts without forced cooling |
| Junction Temperature (Tj) | 200°C max - allows reliable operation in high-temperature industrial environments with derated power |
| Storage Temperature | −55°C to +175°C - compatible with reflow soldering profiles and extended outdoor deployment |
| Package | MHD (JEITA GRZZ0002ZC-A) - standardized 2-pin axial-leaded package with 5 mm pitch compatibility for automated assembly |
Pinout & Package
The HZS6B1LTD-E is housed in the MHD package (JEITA code GRZZ0002ZC-A), a 2-pin axial-leaded silicon planar diode package with cathode band marking, 2.0 mm body diameter, 26.0 mm lead length, and 0.4 mm lead diameter. It is RoHS-compliant and rated for manual or high-speed automatic insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-side reference node | Connected to regulated output or feedback network; polarity must be observed to maintain reverse-bias operation |
| 2 (Anode) | Low-side return path | Typically tied to ground or common reference plane; establishes forward voltage drop during transient overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | 1/3–1/10 lower noise than HZ-series - directly improves SNR in precision ADC references and op-amp bias networks |
| Stable low-impedance regulation | 80 Ω dynamic resistance at 0.5 mA - maintains <±10 mV output shift under 1 mA load step changes |
| Wide operating temperature range | −55°C to +175°C storage, 200°C junction limit - supports use in automotive engine control modules and industrial motor drives |
| Automated assembly compatibility | 5 mm pitch, MHD package - enables direct integration into high-volume PCB assembly lines without retooling |
| Low leakage performance | ≤1 μA at 2.0 V reverse bias - reduces quiescent current in always-on sensor nodes and backup power circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 (Diodes Inc.) | 5.6 V nominal, 80 Ω rd, but 300 mW Pd and higher noise vs. HZS6B1LTD-E | Limited to lower-power portable instruments; not qualified for industrial temp range | Select when cost sensitivity outweighs noise and thermal performance requirements |
| MMSZ5232B (ON Semiconductor) | 5.6 V nominal, 100 Ω rd, 500 mW Pd, but 10 μA IR at 2 V - 10× higher leakage | Suitable for general-purpose supplies but unsuitable for ultra-low-IQ designs | Choose only if higher power handling is prioritized over leakage and noise specs |
Compared with BZX84-C5V6 and MMSZ5232B, the HZS6B1LTD-E delivers superior noise performance, tighter VZ tolerance, and lower leakage - making it the preferred choice for precision analog systems where reference stability and signal fidelity are design-critical.

FAQ
What is the zener voltage tolerance of HZS6B1LTD-E?
The HZS6B1LTD-E has a specified zener voltage range of 5.5 V minimum to 5.8 V maximum at 0.5 mA test current, corresponding to a ±2.7% tolerance around the nominal 5.65 V midpoint. This tight tolerance supports accurate voltage scaling in precision instrumentation and feedback loops without post-manufacturing trimming.
Does HZS6B1LTD-E support RoHS-compliant assembly processes?
Yes, HZS6B1LTD-E is RoHS-compliant per EU Directive 2011/65/EU and features lead-free termination plating compatible with standard Pb-free reflow profiles. The MHD package meets JEITA GRZZ0002ZC-A specifications and is qualified for both wave and reflow soldering per J-STD-020.
How does the noise performance of HZS6B1LTD-E compare to standard Zener diodes?
HZS6B1LTD-E exhibits approximately 1/3 to 1/10 the noise level of legacy HZ-series Zener diodes due to its optimized planar diffusion process and junction geometry. This reduction directly improves signal-to-noise ratio in applications such as precision ADC references and low-level sensor signal conditioning.
What is the maximum power dissipation for HZS6B1LTD-E at 70°C ambient?
Based on the derating curve in Figure 3 of the HZS-L Series datasheet (REJ03G0166-0300), HZS6B1LTD-E maintains 400 mW power dissipation up to ~50°C ambient; at 70°C, allowable Pd drops to approximately 280 mW. Designers must apply thermal derating to avoid exceeding 200°C junction temperature.
Can HZS6B1LTD-E be used in place of HZS6B2L or HZS6B3L?
No - HZS6B1LTD-E is not interchangeable with HZS6B2L (5.6–5.9 V) or HZS6B3L (5.7–6.0 V) due to non-overlapping zener voltage ranges. Each variant targets distinct regulation bands; substitution would cause out-of-spec output voltage in closed-loop systems relying on precise VZ matching.
