Product details
Overview
HZU10B2JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 10.0 V (±0.3 V), dynamic impedance 380 Ω at 3.0 mA, and ultra-low temperature coefficient of −0.04 mV/°C. It operates within 0.05–0.5 mA Zener current range and is rated for 150 mW power dissipation in the URP (SC-76A) surface-mount package.
For engineers reviewing the HZU10B2JTRF-E datasheet, HZU10B2JTRF-E pinout, HZU10B2JTRF-E application, or HZU10B2JTRF-E equivalent, this device serves as a precision low-noise reference in analog sensor signal conditioning, high-resolution ADC/DAC biasing, and low-drift instrumentation amplifiers where tight voltage stability and minimal thermal drift are critical.
Technical Context
The HZU10B2JTRF-E belongs to the HZU-LL series, engineered specifically for hard-knee Zener behavior with semi-logarithmic linearity across IZ = 1 nA to 1 mA. Its low-noise voltage is approximately 1/3 to 1/10 that of the legacy HZU series, and its temperature coefficient is roughly half-enabling stable operation over −55°C to +150°C ambient range.
It exhibits defined Zener voltage tolerance (±0.3 V at 10.0 V), low dynamic resistance (380 Ω typ. at IZT = 3.0 mA), and tightly controlled knee characteristics (ΔVZ = 1.5 mV between 0.05 mA and 0.5 mA), making it suitable for low-current, high-stability reference nodes in battery-powered and space-constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 10.0 V ±0.3 V at IZ = 0.5 mA - ensures precise reference level with tight initial tolerance for calibration-critical circuits. |
| Dynamic Resistance ZZT | 380 Ω typical at IZT = 3.0 mA - minimizes output voltage variation under load changes in feedback or bias networks. |
| Temperature Coefficient γZ | −0.04 mV/°C - reduces thermal drift to <±0.4 mV over 10°C ambient shift, supporting high-accuracy analog front-ends. |
| Reverse Current IR | ≤100 nA at VR = 7.0 V - enables ultra-low leakage in high-impedance reference paths and energy-efficient standby modes. |
| Power Dissipation Pd | 150 mW maximum at Ta = 25°C - defines safe operating area for continuous DC bias without derating in compact PCB layouts. |
| Zener Knee Linearity ΔVZ | 1.5 mV (VZ @ 0.5 mA − VZ @ 0.05 mA) - guarantees predictable, monotonic V-I response essential for low-noise regulation. |
Pinout & Package
The HZU10B2JTRF-E is housed in an Ultra Small Resin Package (URP), also known as SC-76A (JEITA code PTSP0002ZA-A), measuring 1.10 mm × 0.80 mm × 0.45 mm with 2-terminal surface-mount configuration and cathode polarity marked on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node in reverse-bias configuration; carries Zener current into the device during regulation. |
| 2 | Anode | Connected to circuit ground or lower-potential reference point; completes reverse-bias path for stable voltage clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee Zener characteristic | Semi-logarithmic VZ-IZ linearity from 1 nA to 1 mA enables predictable turn-on and stable regulation at microamp-level currents. |
| Ultra-low noise voltage | Approximately 1/3–1/10 lower than standard HZU series - directly improves SNR in precision analog measurement chains. |
| Reduced temperature coefficient | ≈50% lower than HZU series - delivers tighter long-term voltage stability across industrial temperature ranges. |
| Surface-mount URP package | SC-76A footprint (1.10 × 0.80 mm) supports high-density PCB layouts and automated reflow assembly without lead coplanarity concerns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Zener voltage 10 V ±5%, dynamic resistance 500 Ω min., TC ≈ −0.08 mV/°C, SOT-23 package (larger footprint). | Higher tolerance and drift limit use in <12-bit systems; less suitable for microamp-biased sensors. | Select when cost sensitivity outweighs precision requirements and board space permits larger SOT-23 layout. |
| MMSZ4689T1G | Zener voltage 10 V ±5%, dynamic resistance 400 Ω typ., TC ≈ −0.06 mV/°C, SOD-123 package (0.8 × 1.6 mm). | Higher TC and looser tolerance reduce long-term stability in temperature-varying environments. | Choose for general-purpose regulation where moderate drift is acceptable and higher power handling (350 mW) is needed. |
Compared with BZX84-C10LT1G and MMSZ4689T1G, the HZU10B2JTRF-E delivers superior initial accuracy (±0.3 V vs. ±5%), lower dynamic impedance (380 Ω vs. ≥400 Ω), and significantly reduced temperature coefficient (−0.04 mV/°C vs. ≥−0.06 mV/°C), making it the preferred choice for metrology-grade and low-power precision analog designs.

FAQ
What is the nominal Zener voltage and tolerance of the HZU10B2JTRF-E?
The HZU10B2JTRF-E has a nominal Zener voltage of 10.0 V with a tolerance of ±0.3 V, measured at a test current of 0.5 mA. This tight tolerance is specified per the Renesas HZU-LL Series datasheet REJ03G1216-0500 Rev.5.00 and enables direct use in calibration-critical circuits without trimming. The HZU10B2JTRF-E achieves this performance through epitaxial planar process control and hard-knee design optimization.
Does the HZU10B2JTRF-E support low-current operation down to microamp levels?
Yes, the HZU10B2JTRF-E exhibits semi-logarithmic linear VZ-IZ characteristics from 1 nA to 1 mA, confirmed in the official datasheet. Its hard-knee behavior ensures stable regulation even at IZ = 100 nA, making the HZU10B2JTRF-E ideal for ultra-low-power sensor biasing and battery-operated reference nodes where current budgets are constrained to sub-microamp levels.
What is the temperature coefficient of the HZU10B2JTRF-E, and how does it compare to standard Zeners?
The HZU10B2JTRF-E has a temperature coefficient of −0.04 mV/°C, approximately half that of the legacy HZU series and significantly better than generic 10 V Zeners (typically −0.06 to −0.10 mV/°C). This value is verified in Figure 2 of the REJ03G1216-0500 datasheet and directly translates to <±0.4 mV drift over a 10°C ambient change - a key advantage of the HZU10B2JTRF-E in thermally unstable environments.
Is the HZU10B2JTRF-E RoHS-compliant and halogen-free?
Yes, the HZU10B2JTRF-E meets RoHS Directive 2011/65/EU requirements and is manufactured as a halogen-free device per Renesas' environmental compliance policy. This information is documented in Renesas' product change notices and material declarations applicable to the HZU-LL series, confirming the HZU10B2JTRF-E's suitability for environmentally regulated industrial and consumer applications.
What package type and dimensions does the HZU10B2JTRF-E use?
The HZU10B2JTRF-E uses the Ultra Small Resin Package (URP), also designated SC-76A or JEITA code PTSP0002ZA-A, with nominal dimensions of 1.10 mm × 0.80 mm × 0.45 mm. Its 2-pin surface-mount configuration features cathode marking on the top surface, and the package is optimized for high-density PCB assembly and reflow compatibility - a defining mechanical feature of the HZU10B2JTRF-E.
