Product details
Overview
HZU6B1LTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 5.8 V (min 5.6 V, max 6.0 V), dynamic resistance 400 Ω at IZT = 5 mA, and ultra-low noise voltage (~1/3–1/10 of standard HZU series). It operates within −55°C to +150°C storage range and dissipates up to 150 mW at Ta = 25°C.
For engineers reviewing the HZU6B1LTRF-E datasheet, HZU6B1LTRF-E pinout, HZU6B1LTRF-E application, or HZU6B1LTRF-E equivalent, this page delivers verified electrical characteristics, package geometry, thermal derating behavior, low-noise Zener performance metrics, and direct alternative options for precision analog reference design.
Technical Context
The HZU6B1LTRF-E belongs to the HZU-LL Series, engineered specifically for stable, low-noise voltage regulation in analog signal chains where reference stability under varying load and temperature is critical. Its semi-logarithmic linear VZ–IZ characteristic holds from 1 nA to 1 mA, enabling predictable behavior across micro-power to medium-current biasing.
It features a temperature coefficient of approximately −1.5 mV/°C (−0.03 %/°C) - roughly half that of the legacy HZU series - and uses an epitaxial planar structure to minimize flicker noise and improve knee sharpness. The device is rated for junction temperatures up to 150°C and exhibits tight Zener voltage tolerance (±0.2 V at 5.8 V nominal).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V min to 6.0 V max at IZ = 5 mA - ensures stable reference within ±3.4% tolerance for precision biasing. |
| Dynamic Resistance (ZZT) | 400 Ω typical at IZT = 5 mA - limits output impedance drift under load variation in feedback networks. |
| Reverse Current (IR) | ≤100 nA at VR = 4.0 V - enables ultra-low leakage in high-impedance reference nodes. |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - defines maximum continuous DC power before thermal derating applies. |
| Temperature Coefficient (γZ) | −1.5 mV/°C (−0.03 %/°C) - reduces reference drift by ~50% vs. HZU series, improving long-term stability. |
| Noise Voltage | ~1/3 to 1/10 lower than HZU series - directly lowers integrated RMS noise in ADC reference or op-amp bias circuits. |
| Junction Temperature (Tj) | 150°C max - supports operation in thermally constrained industrial or automotive under-hood environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5231BT1G | Zener voltage 5.1 V (±5%), ZZT = 17 Ω at 20 mA, higher noise, no hard-knee linearity spec. | Higher current operation (20 mA), less suitable for sub-1 mA precision biasing or low-noise analog chains. | Choose when cost sensitivity outweighs noise and knee-sharpness requirements; verify thermal derating at 150 mW. |
| BZX84-C5V6 | Zener voltage 5.6 V (±5%), ZZT = 40 Ω at 5 mA, no specified noise reduction or γZ improvement. | Lacks documented low-noise or reduced-TC performance; intended for general-purpose regulation, not metrology-grade references. | Select only for non-critical voltage clamping or coarse biasing where ±5% tolerance and higher drift are acceptable. |
Compared with MMSZ5231BT1G and BZX84-C5V6, the HZU6B1LTRF-E delivers superior noise suppression, tighter VZ tolerance (±0.2 V vs. ±5%), and halved temperature coefficient - making it uniquely suited for high-fidelity analog reference designs where stability and spectral purity are mandatory.

FAQ
What is the nominal Zener voltage of the HZU6B1LTRF-E?
The HZU6B1LTRF-E has a nominal Zener voltage of 5.8 V, with a guaranteed range of 5.6 V to 6.0 V at IZ = 5 mA. This tight tolerance (±0.2 V) supports high-accuracy voltage referencing in analog circuits where standard ±5% Zeners would introduce unacceptable error. The HZU6B1LTRF-E maintains this specification across its qualified operating temperature range.
Does the HZU6B1LTRF-E support ultra-low-current operation?
Yes, the HZU6B1LTRF-E exhibits semi-logarithmic linear VZ–IZ behavior from 1 nA to 1 mA, enabling stable regulation even at nanoampere bias currents. Its reverse current is ≤100 nA at 4.0 V, making the HZU6B1LTRF-E ideal for micro-power sensor nodes and energy-harvesting applications where supply current must remain below 1 µA.
How does the noise performance of the HZU6B1LTRF-E compare to standard Zener diodes?
The HZU6B1LTRF-E delivers approximately 1/3 to 1/10 the noise voltage of the legacy HZU series, achieved via epitaxial planar construction and optimized doping profile. This reduction directly lowers integrated RMS noise in reference paths - a measurable advantage in 16-bit+ ADCs and low-noise amplifier bias networks where the HZU6B1LTRF-E replaces generic Zeners.
What is the temperature coefficient of the HZU6B1LTRF-E?
The HZU6B1LTRF-E has a temperature coefficient of −1.5 mV/°C (−0.03 %/°C), approximately half that of the standard HZU series. This improved TC minimizes reference drift over temperature, supporting stable operation in industrial environments where ambient shifts from −40°C to +85°C - a key differentiator for the HZU6B1LTRF-E in precision analog designs.
Is the HZU6B1LTRF-E compatible with standard SMT reflow processes?
Yes, the HZU6B1LTRF-E uses the Ultra Small Resin Package (URP, SC-76A) with JEITA code PTSP0002ZA-A, qualified for standard lead-free reflow profiles. Its dimensions (1.6 × 0.8 × 0.45 mm) and thermal mass allow compatibility with Type II and III reflow cycles without delamination or parametric shift - confirmed per Renesas reliability testing for the HZU-LL Series, including the HZU6B1LTRF-E.
