Product details
Overview
HZU11B1JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 11 V (min 10.5 V, max 11.5 V), dynamic resistance 450 Ω at IZT = 5 mA, and ultra-small URP surface-mount package. It delivers stable reference performance in precision analog circuits requiring minimal noise and tight temperature coefficient.
For engineers reviewing the HZU11B1JTRF-E datasheet, HZU11B1JTRF-E pinout, HZU11B1JTRF-E application, or HZU11B1JTRF-E equivalent, key selection criteria include its 11 V Zener voltage tolerance, low 0.03 %/°C temperature coefficient, 150 mW power dissipation limit, and compatibility with high-density PCB layouts due to its SC-76A (URP) footprint.
Technical Context
The HZU11B1JTRF-E belongs to the HZU-LL series, engineered specifically for low-noise voltage references where conventional Zener diodes exhibit excessive knee nonlinearity and thermal drift. Its semi-logarithmic Vz–Iz linearity spans six decades (1 nA to 1 mA), enabling accurate operation across wide current ranges without external compensation.
Unlike standard Zeners, the HZU11B1JTRF-E achieves ~50 % lower temperature coefficient and ~70 % lower noise voltage versus legacy HZU-series parts. Its junction design and epitaxial process yield tightly controlled Zener voltage distribution and predictable dynamic impedance behavior under varying load and thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.5 V min / 11.5 V max at IZT = 5 mA - defines stable reference point for biasing or regulation within ±4.5 % tolerance |
| Dynamic Resistance (ZZT) | 450 Ω typical at IZT = 5 mA - determines output impedance and load regulation sensitivity in reference circuits |
| Temperature Coefficient (γZ) | 0.03 %/°C - enables <±0.33 V drift over −40°C to +85°C ambient, critical for precision instrumentation |
| Power Dissipation (PD) | 150 mW maximum at TA = 25°C - sets upper bound on safe operating current (IZ ≤ 13.6 mA at 11 V) |
| Reverse Current (IR) | 100 nA max at VR = 9 V - ensures minimal leakage-induced error in high-impedance reference nodes |
| Junction Temperature (Tj) | 150°C maximum - supports reliable operation in thermally constrained industrial environments |
Pinout & Package
Package: Ultra Small Resin Package (URP), JEITA code SC-76A, Renesas code PTSP0002ZA-A, dimensions 1.70 mm × 0.80 mm × 0.55 mm (L × W × H), mass 0.004 g. Surface-mount compatible with standard reflow profiles.
| 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 | Semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA enables stable reference generation without minimum current constraints |
| Low-noise voltage performance | Approximately 1/3 to 1/10 lower noise than standard HZU-series diodes - reduces RMS voltage fluctuation in sensitive ADC/DAC references |
| Reduced temperature coefficient | ~50 % lower γZ vs. HZU series - improves long-term stability in unregulated thermal environments |
| Ultra-compact URP package | SC-76A footprint (1.7 × 0.8 mm) supports high-density PCB layouts and automated placement in space-constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11LT1G | Zener voltage 10.4–11.6 V; higher ZZT (600 Ω typ); γZ = 0.06 %/°C; SOT-23 package (larger footprint) | Higher noise and drift limit use in sub-12-bit systems; less suitable for ultra-low-current biasing | Select when cost sensitivity outweighs precision requirements and board area permits larger SOT-23 |
| MMSZ5240BT1G | Zener voltage 10.0–11.0 V; ZZT = 500 Ω typ; γZ = 0.05 %/°C; same URP-equivalent SOD-123FL package but no hard-knee linearity spec | Lacks documented semi-log VZ–IZ linearity; not validated for <1 µA operation | Acceptable for general-purpose regulation where 11 V tolerance >±5 % is acceptable and noise <10 µVRMS is not required |
Compared with BZX84-C11LT1G and MMSZ5240BT1G, the HZU11B1JTRF-E provides superior low-current linearity, lower temperature drift, and lower noise-making it the only option among the three qualified for metrology-grade reference designs below 1 µA operating current.

FAQ
What is the Zener voltage tolerance of the HZU11B1JTRF-E?
The HZU11B1JTRF-E has a Zener voltage range of 10.5 V to 11.5 V at test current IZT = 5 mA, corresponding to ±4.5 % tolerance around the nominal 11 V rating. This specification is guaranteed per Renesas datasheet REJ03G1216-0500 Rev.5.00 and applies across the full operating temperature range of −55°C to +150°C junction temperature.
Does the HZU11B1JTRF-E support operation at very low currents?
Yes, the HZU11B1JTRF-E exhibits semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, enabling stable reference behavior down to nanoampere-level bias currents. This hard-knee characteristic is explicitly confirmed in the Renesas HZU-LL series datasheet and distinguishes the HZU11B1JTRF-E from standard Zener diodes that require ≥100 µA for regulation.
What is the temperature coefficient of the HZU11B1JTRF-E?
The HZU11B1JTRF-E has a temperature coefficient of 0.03 %/°C, approximately half that of the legacy HZU series. This value is derived from the slope of VZ vs. temperature curves in Figure 2 of the official datasheet and ensures <±0.33 V total drift over a −40°C to +85°C ambient range.
Is the HZU11B1JTRF-E RoHS compliant and lead-free?
Yes, the HZU11B1JTRF-E is RoHS compliant and lead-free, consistent with Renesas Electronics' environmental policy and the specifications outlined in REJ03G1216-0500. The URP package uses lead-free solderable terminations and conforms to JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1).
What package type does the HZU11B1JTRF-E use?
The HZU11B1JTRF-E uses the Ultra Small Resin Package (URP), also known as SC-76A, with JEITA code PTSP0002ZA-A. Its dimensions are 1.70 mm × 0.80 mm × 0.55 mm, and it features a two-terminal surface-mount configuration with cathode marked on terminal 1.
