Product details
Overview
HZU36B-JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 3.6 V (min 3.4 V, max 3.8 V), dynamic resistance 370 Ω at IZT = 2.0 mA, and ultra-low noise voltage (~1/3–1/10 of standard HZU series). It operates in surface-mount URP (Ultra small Resin Package) and targets precision analog circuits requiring stable low-current biasing.
For engineers reviewing the HZU36B-JTRF-E datasheet, HZU36B-JTRF-E pinout, HZU36B-JTRF-E application, or HZU36B-JTRF-E equivalent, key selection criteria include its semi-logarithmic VZ-IZ linearity from 1 nA to 1 mA, temperature coefficient of −0.03 mV/°C (typical), and suitability for low-power, noise-sensitive reference designs in portable instrumentation and sensor signal conditioning.
Technical Context
The HZU36B-JTRF-E implements a hard-knee Zener breakdown mechanism with epitaxial planar construction to minimize noise generation and improve knee sharpness. Its VZ-IZ characteristic follows semi-logarithmic linearity across six decades of current (1 nA–1 mA), enabling predictable behavior in sub-microamp biasing regimes.
It exhibits a temperature coefficient of −0.03 mV/°C (typical) and −0.04 %/°C (typical), approximately half that of the legacy HZU series, reducing thermal drift in precision references. The device is rated for PD = 150 mW at TA = 25°C and supports junction temperatures up to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V (min) to 3.8 V (max) at IZ = 0.5 mA - defines stable reference range under low-current operation |
| Dynamic Resistance (ZZT) | 370 Ω (max) at IZT = 2.0 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 100 nA (max) at VR = 1.0 V - ensures minimal leakage in high-impedance bias networks |
| Temperature Coefficient (γZ) | −0.03 mV/°C (typ), −0.04 %/°C (typ) - enables <±1 mV drift over 0–70°C ambient range |
| Noise Voltage | ~1/3 to 1/10 of HZU-series diodes - directly reduces RMS noise in reference outputs below 10 Hz |
| Power Dissipation (PD) | 150 mW (max) at TA = 25°C - sets maximum continuous DC bias power without derating |
| Junction Temperature (Tj) | 150°C (max) - defines upper thermal limit for reliability in sealed or high-density PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5226BS-7-F | Zener voltage 3.3 V (±5%), higher noise, no specified semi-log linearity, SOD-323 package | General-purpose regulation only; unsuitable for sub-µA biasing or low-noise reference use | Select when cost sensitivity outweighs noise and linearity requirements |

FAQ
What is the nominal Zener voltage of the HZU36B-JTRF-E and its tolerance range?
The HZU36B-JTRF-E has a nominal Zener voltage of 3.6 V, with a guaranteed range of 3.4 V (minimum) to 3.8 V (maximum) measured at IZ = 0.5 mA. This ±0.2 V tolerance reflects tight process control for precision reference use, and the device maintains this specification across its rated operating temperature range of −55°C to +150°C. The HZU36B-JTRF-E achieves this stability through epitaxial planar construction and hard-knee Zener design.
Does the HZU36B-JTRF-E support operation at very low bias currents, and what is its linearity behavior?
Yes, the HZU36B-JTRF-E supports stable operation from 1 nA to 1 mA with semi-logarithmic VZ-IZ linearity - a key differentiator from standard Zeners. This behavior is confirmed in the datasheet's Figure 1 and enables predictable voltage output even in nanoamp-level bias networks. The HZU36B-JTRF-E leverages this linearity for precision applications such as sensor front-end biasing where conventional diodes exhibit excessive curvature.
How does the noise performance of the HZU36B-JTRF-E compare to earlier Renesas Zener families?
The HZU36B-JTRF-E delivers approximately 1/3 to 1/10 the noise voltage of the legacy HZU series, as explicitly stated in the "Features" section of the datasheet. This ultra-low noise is achieved via optimized epitaxial planar structure and hard-knee breakdown physics. For designers using the HZU36B-JTRF-E in ADC reference or op-amp bias circuits, this translates directly to lower RMS noise floor and improved signal-to-noise ratio in sub-10 Hz bandwidths.
What is the temperature coefficient of the HZU36B-JTRF-E, and how does it impact reference stability?
The HZU36B-JTRF-E has a typical temperature coefficient of −0.03 mV/°C and −0.04 %/°C, approximately half that of the HZU series. This reduced drift means the HZU36B-JTRF-E contributes less than ±0.5 mV error over a 0–70°C ambient range - critical for unregulated or thermally variable environments. The datasheet confirms this value in Figure 2 and specifies it as a key advantage for precision reference design.
Is the HZU36B-JTRF-E compatible with standard reflow soldering processes for surface-mount assembly?
Yes, the HZU36B-JTRF-E uses the URP (Ultra small Resin Package) with JEITA code PTSP0002ZA-A and SC-76A footprint, which is qualified for standard lead-free reflow profiles per J-STD-020. Its maximum junction temperature rating of 150°C and package mass of 0.004 g ensure compatibility with typical peak reflow temperatures of 245–260°C. The HZU36B-JTRF-E's thermal characteristics and package dimensions are fully documented in the "Package Dimensions" section on page 4 of the datasheet.
