Product details
Overview
HZS5BLLTA-E from Renesas Electronics is a silicon planar Zener diode optimized for hard-knee, low-noise voltage reference applications at low currents (IZ = 1 nA to 1 mA), with nominal Zener voltage 4.6–5.0 V, dynamic impedance ≤380 Ω at IZT = 3.0 mA, and temperature coefficient < ±0.05 %/°C. It is used in precision analog front-ends, sensor biasing, and low-power voltage regulation circuits.
For engineers reviewing the HZS5BLLTA-E datasheet, HZS5BLLTA-E pinout, HZS5BLLTA-E application, or HZS5BLLTA-E equivalent, key selection criteria include its sharp breakdown knee at microamp-level currents, low noise performance (~1/10 that of conventional zeners), and suitability for automated 5 mm-pitch insertion in high-reliability industrial instrumentation.
Technical Context
The HZS5BLLTA-E employs a planar diffusion structure to achieve semilogarithmic linear Vz–Iz characteristics across 1 nA–1 mA, enabling stable reference generation without external current boosting. Its hard-knee behavior minimizes voltage hysteresis and improves repeatability in low-current bias networks.
Designed for operation at IZK = 0.5 µA and IZT = 3.0 mA, it delivers ∆VZ1 ≤ 0.5 V and ∆VZ2 ≤ 0.6 V - quantifying tight linearity over two decades of current - and exhibits γZ < ±0.05 %/°C, supporting stable references in ambient-temperature-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.6–5.0 V at IZ = 0.5 mA - defines precise low-current reference point for analog signal conditioning |
| Dynamic Impedance (ZZT) | ≤380 Ω at IZT = 3.0 mA - ensures minimal output voltage shift under load transients |
| Reverse Current (IR) | ≤100 nA at VR = 1.0 V - enables ultra-low leakage biasing in battery-powered sensors |
| Temperature Coefficient (γZ) | < ±0.05 %/°C - supports stable reference performance across –40°C to +85°C ambient |
| Power Dissipation (Pd) | 250 mW - allows continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - supports reliability in thermally constrained industrial enclosures |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated voltage node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Ground or low-impedance return path; establishes reference potential for bias network |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee VZ–IZ linearity | ∆VZ1 ≤ 0.5 V and ∆VZ2 ≤ 0.6 V - enables accurate low-current referencing without active compensation |
| Low-noise operation | ~1/10 noise vs. standard zeners - reduces RMS voltage error in high-gain sensor amplifiers |
| Low-current stability | Specified down to IZ = 1 nA - supports nanoamp-level biasing in CMOS analog 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-C4V7 (Diodes Inc.) | Higher ZZT = 90 Ω (at 5 mA), wider VZ tolerance (±5%), γZ ≈ ±0.08 %/°C | Limited to general-purpose regulation; not specified for <1 µA operation or low-noise design | Acceptable for cost-sensitive non-precision applications where 0.5% reference stability suffices |
| MMSZ4685 (ON Semiconductor) | VZ = 4.7 V ±5%, ZZT = 130 Ω (at 5 mA), no hard-knee characterization below 10 µA | Not validated for nanoamp-level linearity; higher noise floor invalidates use in sensor front-ends | Suitable only for power rail clamping or coarse voltage detection - not for precision analog reference |
Compared with BZX84-C4V7 and MMSZ4685, the HZS5BLLTA-E provides superior low-current linearity (∆VZ2 ≤ 0.6 V), lower noise, and tighter temperature coefficient - making it the only option qualified for metrology-grade and battery-constrained analog systems requiring stable reference performance below 1 µA.

FAQ
What is the Zener voltage tolerance of HZS5BLLTA-E at 0.5 mA?
The HZS5BLLTA-E has a guaranteed Zener voltage range of 4.6 V to 5.0 V when tested at IZ = 0.5 mA, per Renesas REJ03G0167-0300 Rev.3.00. This ±0.2 V window reflects tight process control for low-current reference accuracy, and the specification is verified during final test at 25°C ambient.
Does HZS5BLLTA-E support operation below 1 µA?
Yes, the HZS5BLLTA-E is characterized down to IZ = 1 nA, with documented linearity metrics ∆VZ1 and ∆VZ2 confirming stable behavior across six decades of current. Its hard-knee design ensures predictable VZ even at nanoamp bias levels - a capability not offered by standard Zener diodes like the MMSZ4685.
What is the maximum allowable junction temperature for HZS5BLLTA-E?
The absolute maximum junction temperature for HZS5BLLTA-E is 175°C, as stated in the Absolute Maximum Ratings table of the Renesas datasheet REJ03G0167-0300. Derating begins at 25°C ambient, with Pd decreasing linearly to zero at 175°C - enabling reliable use in sealed industrial enclosures with limited airflow.
Is HZS5BLLTA-E RoHS compliant?
Yes, HZS5BLLTA-E meets EU RoHS Directive requirements. Renesas confirms environmental compliance for the HZS-LL Series in accordance with applicable regulations, including restriction of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE. Full material declarations are available upon request through Aetrix Electronics.
What package type does HZS5BLLTA-E use, and is it compatible with automated insertion?
HZS5BLLTA-E uses the MHD package (JEITA code GRZZ0002ZC-A), a 2-pin axial-leaded molded plastic case with 5 mm pitch - explicitly rated for high-speed automatic insertion per the Renesas datasheet. The navy-blue cathode band and standardized dimensions ensure compatibility with standard pick-and-place feeders and wave-solder pallets.
