Product details
Overview
HZU5.6Z-JTRF-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 5.6 V at 0.5 mA, exhibits ultra-low noise voltage (~1/3 to 1/10 that of standard HZU series), and features a temperature coefficient of −1.5 mV/°C (typical). Its URP (Ultra small Resin Package) supports high-density surface-mount designs in precision analog circuits.
For engineers reviewing the HZU5.6Z-JTRF-E datasheet, HZU5.6Z-JTRF-E pinout, HZU5.6Z-JTRF-E application, or HZU5.6Z-JTRF-E equivalent, key selection criteria include its semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, low dynamic impedance (380 Ω typ. at IZT = 0.5 mA), and suitability for low-power, low-drift reference nodes in sensor signal conditioning and ADC biasing.
Technical Context
The HZU5.6Z-JTRF-E belongs to the HZU-LL Series, engineered specifically for improved noise and thermal stability over legacy HZU devices. Its Zener voltage is specified with tight tolerance (4.9 V to 5.3 V at IZ = 0.5 mA), and its dynamic resistance (ZZT) remains stable across the test current range due to epitaxial planar construction.
It operates within a junction temperature range of −55°C to +150°C and is rated for 150 mW power dissipation at Ta = 25°C, derating linearly above 25°C per Fig.3. The device's cathode-anode pin arrangement follows SC-76A (URP) footprint PTSP0002ZA-A, with defined terminal positions and mass (0.004 g typ.).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Zener voltage 5.1 V (±5%), higher noise, γZ = −2.5 mV/°C, ZZT = 17 Ω @ 20 mA | Higher test current (20 mA) limits use in µA-biased circuits; better suited for higher-current regulation | Select when higher power handling (>250 mW) and tighter VZ tolerance (±5%) outweigh low-noise requirements |
| BZX84-C5V6 | Zener voltage 5.6 V (±5%), no published noise spec, γZ = −2.0 mV/°C, ZZT = 40 Ω @ 5 mA | Requires ≥5 mA for spec compliance; not characterized below 100 µA - unsuitable for nanoampere linearity | Choose for cost-sensitive, moderate-accuracy applications where ultra-low current operation is unnecessary |
Compared with MMBZ5232BS-7-F and BZX84-C5V6, the HZU5.6Z-JTRF-E uniquely supports validated VZ linearity down to 1 nA and delivers lowest noise and drift among SOT-23/Zener-class alternatives - critical for µA-biased precision references.

FAQ
What is the Zener voltage tolerance of the HZU5.6Z-JTRF-E?
The HZU5.6Z-JTRF-E has a Zener voltage range of 4.9 V to 5.3 V at IZ = 0.5 mA, corresponding to ±5% tolerance around the nominal 5.6 V rating. This specification is confirmed in the Electrical Characteristics table of Renesas document REJ03G1216-0500 Rev.5.00, and applies strictly under DC test conditions at Ta = 25°C. The HZU5.6Z-JTRF-E does not specify tighter tolerance grades such as ±1% or ±2%.
Does the HZU5.6Z-JTRF-E support operation below 1 µA?
Yes, the HZU5.6Z-JTRF-E is explicitly characterized for semi-logarithmic VZ–IZ linearity from IZ = 1 nA up to 1 mA per Renesas REJ03G1216-0500. This makes the HZU5.6Z-JTRF-E suitable for ultra-low-current applications such as nanoampere-biased instrumentation amplifiers or energy-harvesting sensor nodes where conventional Zeners fail to maintain stable voltage.
What is the thermal performance limit of the HZU5.6Z-JTRF-E?
The HZU5.6Z-JTRF-E has a maximum junction temperature (Tj) of 150°C and a storage temperature range of −55°C to +150°C. Its power dissipation is rated at 150 mW at Ta = 25°C, derating linearly with ambient temperature as shown in Fig.3 of REJ03G1216-0500. Exceeding these limits risks irreversible degradation of the HZU5.6Z-JTRF-E's Zener characteristics and noise performance.
Is the HZU5.6Z-JTRF-E RoHS compliant?
Yes, the HZU5.6Z-JTRF-E is RoHS compliant per Renesas Electronics' environmental policy and product declarations. As stated in the colophon and notice sections of REJ03G1216-0500 Rev.5.00, Renesas products comply with EU RoHS Directive requirements, including restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. Compliance documentation is available through Renesas' official website and authorized distribution channels.
How does the noise performance of the HZU5.6Z-JTRF-E compare to standard Zener diodes?
The HZU5.6Z-JTRF-E delivers approximately 1/3 to 1/10 the noise voltage of standard HZU-series Zeners, as stated in the Features section of REJ03G1216-0500. This reduction stems from optimized epitaxial planar process and hard-knee design, making the HZU5.6Z-JTRF-E especially valuable in low-noise reference paths for high-resolution ADCs and precision op-amp circuits where broadband noise directly impacts SNR.
