Product details
Overview
HZU5.6G-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, with dynamic resistance of 380 Ω (typ), temperature coefficient of −0.03 mV/°C, and ultra-low noise voltage-approximately 1/3 to 1/10 that of standard HZU-series diodes. It is used in precision analog front-ends and low-drift sensor biasing circuits.
For engineers reviewing the HZU5.6G-JTRF-E datasheet, HZU5.6G-JTRF-E pinout, HZU5.6G-JTRF-E application, or HZU5.6G-JTRF-E equivalent, this page provides verified electrical parameters, package mapping to URP (SC-76A), cathode/anode terminal roles, and two validated alternative Zener diodes for low-noise reference design.
Technical Context
The HZU5.6G-JTRF-E employs a hard-knee Zener breakdown mechanism with semi-logarithmic linear VZ–IZ characteristics across 1 nA to 1 mA, enabling stable operation at microampere-level bias currents. Its low dynamic impedance (380 Ω typ at IZT = 0.5 mA) and ultra-low temperature coefficient (−0.03 mV/°C) support high-accuracy DC referencing without active compensation.
This device belongs to the HZU-LL series, engineered specifically to reduce both voltage noise and thermal drift versus legacy HZU parts. The Zener voltage tolerance is ±0.4 V (4.9 V to 5.3 V), and it operates within a junction temperature range of −55°C to +150°C under 150 mW power dissipation limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.9 V to 5.3 V at IZ = 0.5 mA - ensures tight DC reference stability for 5 V system rails. |
| Dynamic Resistance (ZZT) | 380 Ω (typ) at IZT = 0.5 mA - minimizes output voltage variation under load transients. |
| Temperature Coefficient (γZ) | −0.03 mV/°C - reduces thermal drift by ~50% vs. standard HZU series, critical for unregulated environments. |
| Reverse Current (IR) | ≤100 nA at VR = 4.0 V - enables ultra-low-power biasing in battery-operated sensor nodes. |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - supports surface-mount placement on compact PCBs without forced cooling. |
| Noise Voltage | ~1/3 to 1/10 of HZU series - directly lowers RMS noise floor in precision ADC reference chains. |
Pinout & Package
Package: Ultra Small Resin Package (URP), JEITA code SC-76A, Renesas code PTSP0002ZA-A, mass 0.004 g. Dimensions: 1.70 mm × 0.80 mm × 0.45 mm (L × W × H), with 2-terminal SMD configuration.
| 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); defines current direction during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee Zener characteristic | Enables sharp, predictable breakdown onset at 5.6 V with minimal knee curvature-ideal for threshold detection and clamping. |
| Semi-logarithmic VZ–IZ linearity | Maintains stable regulation from 1 nA to 1 mA, supporting ultra-low-current biasing in micropower systems. |
| Ultra-low voltage noise | Reduces integrated noise in 0.1 Hz–10 kHz band by factor of 3–10 vs. HZU series-critical for 16+ bit ADC references. |
| Low-temperature-coefficient design | −0.03 mV/°C allows <±1 mV drift over −40°C to +85°C ambient-no external compensation needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232B-7-F (Diodes Inc.) | Zener voltage 5.1 V ±5%, dynamic resistance 17 Ω at 20 mA, noise not specified, TC ≈ −2.5 mV/°C. | Higher current operation (20 mA), unsuitable for µA-biasing; better for general-purpose regulation than precision referencing. | Select when cost-sensitive, high-current regulation is needed-not for low-noise or low-drift use cases. |
| BZX84-C5V6 (Nexperia) | Zener voltage 5.6 V ±5%, dynamic resistance 40 Ω at 5 mA, TC ≈ −2.0 mV/°C, no low-noise characterization. | Standard performance grade; lacks hard-knee linearity and ultra-low noise specification of HZU5.6G-JTRF-E. | Choose for non-critical biasing where thermal drift and broadband noise are not design constraints. |
Compared with MMBZ5232B-7-F and BZX84-C5V6, the HZU5.6G-JTRF-E offers superior low-noise performance, tighter voltage tolerance at low current, and significantly lower temperature coefficient-making it uniquely suited for precision analog signal chains where reference integrity dominates system accuracy.
