Product details
Overview
HZU6C2LTRF-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 6.2 V at 5 mA, exhibits ultra-low noise voltage (~1/3 to 1/10 that of standard HZU series), and features a temperature coefficient of −0.02 mV/°C - approximately half that of the HZU series. Its semi-logarithmic linear VZ–IZ characteristics (1 nA to 1 mA) support precision biasing in analog front-ends and sensor signal conditioning circuits.
For engineers reviewing the HZU6C2LTRF-E datasheet, HZU6C2LTRF-E pinout, HZU6C2LTRF-E application, or HZU6C2LTRF-E equivalent, key selection criteria include its hard-knee Zener behavior, ultra-low noise performance, tight ±5% Zener voltage tolerance at IZ = 5 mA, and suitability for low-current (<1 mA) reference designs requiring stable DC bias with minimal thermal drift.
Technical Context
The HZU6C2LTRF-E belongs to the HZU-LL Series, engineered specifically for low-noise, high-stability voltage references where conventional Zener diodes exhibit excessive knee curvature and noise. Its epitaxial planar structure enables sharp breakdown characteristics and reduced flicker noise compared to diffused-junction Zeners.
It operates within a 1 nA–1 mA reverse current range with semi-logarithmic linearity, supports DC testing only per specification, and maintains a dynamic resistance of 380 Ω at IZT = 5 mA - critical for minimizing output impedance in shunt-regulated topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% at IZ = 5 mA - defines precise DC reference level for analog circuit biasing |
| Dynamic Resistance (ZZT) | 380 Ω typical at IZT = 5 mA - ensures low output impedance and minimal load-induced voltage shift |
| Temperature Coefficient (γZ) | −0.02 mV/°C - reduces thermal drift by ~50% vs. legacy HZU series, improving long-term stability |
| Reverse Current (IR) | ≤100 nA at VR = 4.9 V - enables ultra-low leakage in high-impedance reference nodes |
| Power Dissipation (Pd) | 150 mW maximum - constrains usable current range to ≤24 mA at 6.2 V, supporting compact SMT layout |
| Junction Temperature (Tj) | 150°C maximum - allows operation in industrial ambient environments up to +100°C with derating |
Pinout & Package
Package: Ultra Small Resin Package (URP), JEITA code PTSP0002ZA-A, SC-76A outline, mass 0.004 g. Surface-mount compatible with 0.8 mm × 1.55 mm footprint and 0.15 mm minimum A1 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 enabling accurate low-current regulation without soft knee ambiguity |
| Ultra-low noise voltage | ~1/3 to 1/10 lower than HZU series - directly reduces RMS noise in precision reference paths |
| Semi-logarithmic VZ–IZ linearity | Valid from 1 nA to 1 mA - supports stable reference generation across wide current scaling ranges |
| Reduced temperature coefficient | Approximately half that of HZU series - improves thermal stability in unregulated ambient conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 | Zener voltage tolerance ±5%, but dynamic resistance 600 Ω at 5 mA; noise voltage ~3× higher; no hard-knee characterization | Lacks verified low-noise performance and semi-log linearity below 10 µA - unsuitable for sub-µA biasing | Select HZU6C2LTRF-E when noise <1 µVRMS and linearity to 1 nA are required |
| MMSZ4687 | 6.2 V nominal, ±5% tolerance, but γZ = −0.05 mV/°C; ZZT = 500 Ω; not specified for hard-knee or low-noise operation | Higher thermal drift limits use in wide-temperature industrial sensors without recalibration | Choose HZU6C2LTRF-E for applications demanding <0.03 mV/°C drift and guaranteed knee sharpness |

What is the Zener voltage tolerance of the HZU6C2LTRF-E?
The HZU6C2LTRF-E has a Zener voltage tolerance of ±5% at IZ = 5 mA, corresponding to a guaranteed range of 5.89 V to 6.51 V. This tolerance is specified under DC test conditions and applies directly to the HZU6C2LTRF-E part number as documented in Renesas' REJ03G1216-0500 datasheet revision 5.00.
Does the HZU6C2LTRF-E support AC-coupled or pulsed operation?
No - the HZU6C2LTRF-E is characterized and rated for DC operation only, as explicitly stated in the Electrical Characteristics table. Its VZ–IZ linearity, noise, and dynamic resistance specifications apply strictly under steady-state DC bias. The HZU6C2LTRF-E is not validated for AC or transient conditions.
What is the maximum reverse current range over which the HZU6C2LTRF-E maintains linearity?
The HZU6C2LTRF-E maintains semi-logarithmic linear VZ–IZ characteristics from IZ = 1 nA to 1 mA, as confirmed in the datasheet's "Electrical Characteristics" section. This 6-decade range enables predictable behavior in ultra-low-current bias networks where the HZU6C2LTRF-E serves as a stable reference node.
Is the HZU6C2LTRF-E RoHS compliant and lead-free?
Yes - the HZU6C2LTRF-E is RoHS compliant and lead-free, consistent with Renesas Electronics' environmental policy and the EU RoHS Directive. The device uses lead-free solderable terminations and complies with all applicable substance restrictions as verified in Renesas' official product documentation for the HZU-LL Series.
What package type does the HZU6C2LTRF-E use, and what are its key mechanical dimensions?
The HZU6C2LTRF-E uses the Ultra Small Resin Package (URP), JEITA code PTSP0002ZA-A, equivalent to SC-76A. Key dimensions are 0.8 mm width (D), 1.55 mm length (E), 0.15 mm minimum A1 height, and 0.004 g mass - optimized for high-density surface-mount assembly in space-constrained PCB layouts.
