Product details
Overview
HZU3.0B1JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications. It delivers a nominal Zener voltage of 3.0 V (2.8–3.2 V), exhibits ultra-low noise voltage (~1/3–1/10 that of standard HZU series), and features a temperature coefficient of −1.0 mV/°C (typical) - approximately half that of the legacy HZU series. Its semi-logarithmic linear VZ–IZ characteristic from 1 nA to 1 mA supports precision biasing in low-current analog circuits.
For engineers reviewing the HZU3.0B1JTRF-E datasheet, HZU3.0B1JTRF-E pinout, HZU3.0B1JTRF-E application, or HZU3.0B1JTRF-E equivalent, key selection criteria include its 3.0 V Zener voltage tolerance, ultra-low noise performance, low-temperature-coefficient stability, URP surface-mount package compatibility, and suitability for low-power reference design in instrumentation and sensor signal conditioning.
Technical Context
The HZU3.0B1JTRF-E operates as a two-terminal, passive voltage reference device with a hard-knee Zener breakdown mechanism enabled by silicon epitaxial planar construction. Its VZ–IZ curve maintains semi-logarithmic linearity over six decades (1 nA to 1 mA), enabling stable regulation even at microamp-level bias currents.
It achieves low-noise operation through optimized epitaxial layer doping and junction geometry, reducing flicker and thermal noise components. The temperature coefficient is minimized via intrinsic material properties and process tuning - not external compensation - resulting in a typical γZ of −1.0 mV/°C, verified across the 25°C to 85°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.8 V min / 3.2 V max at IZ = 0.5 mA - defines tight 3.0 V nominal reference with ±0.2 V tolerance for high-accuracy biasing |
| Noise Voltage | ~1/3 to 1/10 lower than HZU series - enables use in ultra-low-noise amplifiers and precision ADC references |
| Temp. Coefficient (γZ) | −1.0 mV/°C typ - provides improved thermal stability vs. legacy HZU (−2.0 mV/°C typ), reducing drift in wide-temperature environments |
| Dynamic Resistance (ZZT) | 360 Ω typ at IZT = 0.5 mA - ensures minimal output impedance variation under load changes |
| Reverse Current (IR) | ≤100 nA at VR = 1.0 V - guarantees negligible leakage in high-impedance reference nodes |
| Power Dissipation (Pd) | 150 mW max at Ta = 25°C - supports operation in compact SMT layouts without forced cooling |

Package: Ultra Small Resin Package (URP), JEITA code PTSP0002ZA-A, Renesas code SC-76A, mass 0.004 g. Surface-mount compatible with 0.8 mm × 1.55 mm footprint and 0.45 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to lower-potential node (typically ground or common return); completes bias path |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee Zener characteristic | Sharp, well-defined breakdown onset at ~3.0 V enables precise threshold detection without soft turn-on ambiguity |
| Ultra-low noise voltage | Reduces RMS noise contribution in reference paths - critical for sub-16-bit ADCs and low-noise op-amp biasing |
| Semi-logarithmic VZ–IZ linearity | Maintains stable voltage over 1 nA–1 mA current range, supporting wide dynamic range in battery-powered sensors |
| Low temperature coefficient | −1.0 mV/°C typ minimizes drift-induced error in industrial temperature ranges (−40°C to +85°C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431ACDBVR | Adjustable shunt regulator (2.5 V ref), requires external resistors; higher IKA (1 mA min), higher noise density (15 µV/√Hz) | Used where programmable reference or higher current sinking (>1 mA) is needed; unsuitable for sub-100 nA bias designs | Select HZU3.0B1JTRF-E when fixed 3.0 V, ultra-low-noise, and nanoamp-level operation are mandatory |
| BZX84-C3V0LT1G | Standard Zener (3.0 V), higher tempco (−2.5 mV/°C), higher noise, no hard-knee specification, 350 Ω ZZT | Acceptable for general-purpose voltage clamping but lacks precision linearity and low-drift stability for metrology-grade references | Choose HZU3.0B1JTRF-E for applications requiring guaranteed semi-log VZ–IZ behavior and <1.0 mV/°C tempco |
Compared with TL431ACDBVR and BZX84-C3V0LT1G, the HZU3.0B1JTRF-E offers superior thermal stability, lower noise, and verified hard-knee linearity - making it uniquely suited for nanoamp-biased, high-accuracy analog references where passive simplicity and drift-critical performance are non-negotiable.

FAQ
What is the nominal Zener voltage of the HZU3.0B1JTRF-E and how tightly is it specified?
The HZU3.0B1JTRF-E has a nominal Zener voltage of 3.0 V, with a guaranteed range of 2.8 V to 3.2 V at IZ = 0.5 mA. This ±0.2 V tolerance (±6.7%) reflects its hard-knee design and is tighter than many general-purpose Zeners in the same voltage class. The specification is validated per Renesas REJ03G1216-0500 Rev.5.00 test conditions and applies directly to the HZU3.0B1JTRF-E device.
Does the HZU3.0B1JTRF-E require external biasing components to function as a voltage reference?
No, the HZU3.0B1JTRF-E is a two-terminal passive Zener diode and requires only a series current-limiting resistor to operate. It does not need external op-amps, capacitors, or feedback networks. Its semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA allows direct integration into ultra-low-current reference nodes - a key feature confirmed for the HZU3.0B1JTRF-E in the official Renesas datasheet.
How does the temperature coefficient of the HZU3.0B1JTRF-E compare to standard Zener diodes?
The HZU3.0B1JTRF-E exhibits a typical temperature coefficient of −1.0 mV/°C, approximately half that of conventional Zeners like the HZU series (−2.0 mV/°C typ) and significantly better than BZX84-C3V0LT1G (−2.5 mV/°C). This value is measured and specified for the HZU3.0B1JTRF-E across 25°C to 85°C and contributes directly to its suitability in thermally varying environments without additional compensation.
Is the HZU3.0B1JTRF-E RoHS compliant and what is its packaging format?
Yes, the HZU3.0B1JTRF-E is RoHS compliant and supplied in tape-and-reel format per JEDEC standard. Its package is the Ultra Small Resin Package (URP), designated PTSP0002ZA-A (JEITA) and SC-76A (Renesas), with dimensions of 0.8 mm × 1.55 mm × 0.45 mm max. This information is explicitly documented for the HZU3.0B1JTRF-E in Renesas' official package drawings and compliance statements.
Can the HZU3.0B1JTRF-E be used in place of the older HZU3BLL variant?
Yes - the HZU3.0B1JTRF-E is the modern, industry-standard marking for the HZU3BLL device, sharing identical electrical characteristics, package, and performance. The "1JTRF-E" suffix denotes tape-and-reel packaging and RoHS compliance per Renesas' updated ordering nomenclature. All specifications in REJ03G1216-0500 Rev.5.00 apply equivalently to the HZU3.0B1JTRF-E as a direct replacement for HZU3BLL.
