Product details
Overview
HZU6.2B3JTRF from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 6.2 V, dynamic resistance 450 Ω at IZT = 5 mA, and temperature coefficient 2.0 mV/°C. It operates within −55°C to +150°C storage range and dissipates up to 150 mW in the ultra-small URP (SC-76A) surface-mount package.
For engineers reviewing the HZU6.2B3JTRF datasheet, HZU6.2B3JTRF pinout, HZU6.2B3JTRF application, or HZU6.2B3JTRF equivalent, key selection criteria include low-noise performance (1/3–1/10 lower than standard HZU), semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, and tight ±5% Zener voltage tolerance at 5 mA test current.
Technical Context
The HZU6.2B3JTRF belongs to the HZU-LL series, engineered specifically for precision analog references where noise and thermal drift must be minimized. Its epitaxial planar structure enables stable hard-knee breakdown and reduced flicker noise versus conventional Zener diodes.
Electrical behavior is characterized by semi-logarithmic linearity over seven decades of reverse current (1 nA–1 mA), with Zener voltage defined at two test points (IZ = 0.05 mA and 0.5 mA) to calculate ∆VZ = 1.5 V - a metric reflecting knee sharpness and low-current stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±5% at IZ = 5 mA - ensures stable reference point for low-drift analog circuits |
| Dynamic Resistance ZZT | 450 Ω typ. at IZT = 5 mA - minimizes output impedance variation under load changes |
| Reverse Current IR | ≤100 nA at VR = 4.0 V - enables high-impedance biasing and low-leakage sensing |
| Temperature Coefficient γZ | 2.0 mV/°C - half that of standard HZU series, improving thermal stability in unregulated environments |
| Power Dissipation Pd | 150 mW max at Ta = 25°C - defines safe DC operating envelope for PCB thermal design |
| Junction Temperature Tj | 150°C max - supports operation in industrial ambient conditions without derating below 85°C |
| VZ–IZ Linearity | Semi-logarithmic linear from 1 nA to 1 mA - allows accurate modeling and predictable regulation down to nanoampere bias currents |
Pinout & Package
Package: Ultra Small Resin Package (URP), JEITA code PTSP0002ZA-A, SC-76A footprint (1.6 mm × 0.8 mm × 0.55 mm), mass 0.004 g, suitable for high-density SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node; carries reverse-biased current into diode junction |

Key Features
| Feature | Design Value |
|---|---|
| Low-noise voltage reference | 1/3–1/10 lower noise than standard HZU series - critical for high-resolution ADC/DAC biasing and sensor excitation |
| Hard-knee Zener characteristic | VZ–IZ curve exhibits sharp, repeatable turn-on from 1 nA to 1 mA - eliminates ambiguity in low-current regulation thresholds |
| Reduced temperature coefficient | γZ ≈ 2.0 mV/°C - halves thermal drift vs. legacy HZU, enabling tighter reference stability without external compensation |
| Ultra-small URP package | SC-76A outline (1.6 × 0.8 mm) - supports miniaturized portable and space-constrained instrumentation designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687T1G | Zener voltage 6.2 V ±5%, but ZZT = 600 Ω (vs. 450 Ω), γZ = 3.5 mV/°C (vs. 2.0 mV/°C), no specified low-noise characterization | Lacks documented low-noise performance and semi-log linearity guarantee; suited for general-purpose regulation only | Select when cost sensitivity outweighs noise/TC requirements and full HZU-LL performance is not needed |
| BZX84-C6V2 | Zener voltage 6.2 V ±5%, ZZT = 60 Ω at 5 mA (lower), but IR = 1 µA at 4.0 V (10× higher), γZ = 4.0 mV/°C (2× higher) | Higher leakage and drift limit use in high-impedance, low-power, or wide-temperature applications | Prefer for high-current shunt regulation where low ZZT dominates over noise and thermal stability |

FAQ
What is the Zener voltage tolerance and test condition for HZU6.2B3JTRF?
The HZU6.2B3JTRF has a Zener voltage of 6.2 V with ±5% tolerance, measured at a test current of 5 mA (IZ = 5 mA). This tolerance band is guaranteed across the full operating temperature range and reflects the device's qualification for precision reference applications where repeatability and batch consistency are critical. The HZU6.2B3JTRF achieves this specification using epitaxial planar process control and laser trimming during final test.
Does HZU6.2B3JTRF support operation at very low reverse currents?
Yes, the HZU6.2B3JTRF exhibits semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, enabling stable regulation even at nanoampere bias levels. This behavior is confirmed in the official datasheet (REJ03G1216-0500) and distinguishes the HZU6.2B3JTRF from conventional Zeners that typically degrade below 10 µA. The HZU6.2B3JTRF maintains usable regulation down to 1 nA, supporting ultra-low-power sensor biasing and standby reference circuits.
What is the maximum power dissipation and thermal derating behavior of HZU6.2B3JTRF?
The HZU6.2B3JTRF has a maximum power dissipation of 150 mW at Ta = 25°C, with linear derating above 25°C as shown in Figure 3 of the datasheet. Junction temperature is limited to 150°C, and the device remains functional up to 150°C storage temperature. The URP package's small thermal mass requires attention to adjacent heat sources and copper pour area on PCBs - typical thermal resistance θJA is ~330°C/W for standard 1.6 mm × 0.8 mm pad layout.
How does the noise performance of HZU6.2B3JTRF compare to standard Zener diodes?
The HZU6.2B3JTRF delivers approximately 1/3 to 1/10 lower noise voltage than the legacy HZU series, due to its epitaxial planar structure and optimized junction geometry. This reduction is measured across the 10 Hz–10 kHz band and directly improves SNR in precision analog stages. Unlike generic Zeners, the HZU6.2B3JTRF's low-noise specification is explicitly characterized and guaranteed - a key differentiator for HZU6.2B3JTRF in high-fidelity reference applications.
Is HZU6.2B3JTRF RoHS-compliant and halogen-free?
Yes, the HZU6.2B3JTRF meets RoHS Directive 2011/65/EU requirements and is manufactured as a halogen-free device per Renesas' environmental compliance policy. Lead-free solder reflow profiles compatible with J-STD-020D are supported, and the URP package uses matte tin termination. Full material declarations and substance compliance reports are available through Renesas' official portal and apply to all production lots of HZU6.2B3JTRF.
