Product details
Overview
HZU5CLLTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with a nominal Zener voltage of 4.9–5.3 V at 0.5 mA, dynamic resistance of 380 Ω (typ), and ultra-low noise voltage (~1/3 to 1/10 that of standard HZU series). It operates in surface-mount URP (Ultra small Resin Package) and is used in precision analog front-ends and low-drift reference circuits.
For engineers reviewing the HZU5CLLTRF-E datasheet, HZU5CLLTRF-E pinout, HZU5CLLTRF-E application, or HZU5CLLTRF-E equivalent, key selection criteria include its semi-logarithmic Vz–Iz linearity (1 nA to 1 mA), temperature coefficient of −0.03 mV/°C (typ), and suitability for low-power, noise-sensitive voltage regulation where stability under varying load and temperature is critical.
Technical Context
The HZU5CLLTRF-E employs a silicon epitaxial planar structure to achieve hard-knee Zener characteristics with minimal knee curvature, enabling precise low-current regulation. Its Vz–Iz curve remains semi-logarithmically linear across six decades (1 nA to 1 mA), supporting accurate modeling in sub-microamp biasing scenarios.
It exhibits a temperature coefficient of −0.03 mV/°C (typ), approximately half that of the legacy HZU series, reducing thermal drift in reference designs. The device is rated for 150 mW power dissipation at 25°C and junction temperatures up to 150°C, with storage range from −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.9–5.3 V at IZ = 0.5 mA - defines stable reference point for low-current bias networks |
| Dynamic Resistance (ZZT) | 380 Ω (typ) at IZT = 0.5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤100 nA at VR = 3.0 V - ensures minimal leakage in high-impedance reference nodes |
| Temperature Coefficient (γZ) | −0.03 mV/°C (typ) - enables <±1 mV drift over 0–70°C ambient range |
| Noise Voltage | ~1/3 to 1/10 of HZU series - reduces RMS noise contribution in precision ADC references |
| Power Dissipation (Pd) | 150 mW max at Ta = 25°C - constrains maximum continuous bias current to ~28 mA at 5.3 V |
| Package | URP (SC-76A) - 1.7 mm × 0.9 mm footprint supports high-density PCB layout |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5231BT1G | Zener voltage 5.1 V ±5%, ZZT = 17 Ω at 20 mA, higher noise, TC ≈ −2.5 mV/°C | Higher power rating (500 mW) but unsuitable for sub-100 µA biasing due to poor low-current linearity | Prefer HZU5CLLTRF-E when low-current linearity, low noise, or tight TC are required; MMSZ5231BT1G fits higher-current, cost-sensitive applications |
| BZX84-C5V1 | Zener voltage 5.1 V ±5%, ZZT = 60 Ω at 5 mA, no specified low-current linearity or noise data | Standard SOT-23 package (larger footprint); lacks documented 1 nA–1 mA Vz–Iz behavior | Choose HZU5CLLTRF-E for validated microampere-range performance; BZX84-C5V1 acceptable only if design operates ≥1 mA and thermal drift <±5 mV is tolerable |
Compared with MMSZ5231BT1G and BZX84-C5V1, the HZU5CLLTRF-E delivers superior low-current regulation fidelity, lower noise, and tighter thermal stability-making it the preferred choice for precision analog systems where reference integrity at µA bias levels is non-negotiable.

FAQ
What is the Zener voltage tolerance of the HZU5CLLTRF-E?
The HZU5CLLTRF-E has a Zener voltage range of 4.9 V to 5.3 V at IZ = 0.5 mA, corresponding to a ±4% tolerance centered at 5.1 V. This specification is guaranteed per the Renesas REJ03G1216-0500 datasheet and applies under DC test conditions at Ta = 25°C. The HZU5CLLTRF-E maintains this tolerance without derating across its rated junction temperature range.
Does the HZU5CLLTRF-E support operation below 1 µA?
Yes-the HZU5CLLTRF-E exhibits semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, explicitly confirmed in the Renesas datasheet. At 100 nA, its Zener voltage remains within 1.5 mV of the 0.5 mA value (∆VZ = VZ(0.5 mA) – VZ(0.05 mA)), making the HZU5CLLTRF-E uniquely suited for micropower reference designs where conventional Zeners fail to regulate predictably.
What is the thermal coefficient of the HZU5CLLTRF-E, and how does it compare to earlier series?
The HZU5CLLTRF-E has a typical temperature coefficient of −0.03 mV/°C, approximately half that of the standard HZU series. This value is measured across the 25–75°C ambient range and directly contributes to <±1 mV total drift over 0–70°C operation. The improved TC is a core design feature of the HZU-LL series and is verified in Figure 2 of the REJ03G1216-0500 datasheet for the HZU5CLL variant, which matches the HZU5CLLTRF-E.
Is the HZU5CLLTRF-E RoHS compliant and halogen-free?
Yes-the HZU5CLLTRF-E complies with EU RoHS Directive 2011/65/EU and is halogen-free per Renesas' material declarations. The URP package uses lead-free solderable terminations and conforms to J-STD-020 moisture sensitivity level (MSL) 1. Full compliance documentation, including substance declarations and test reports, is available through Renesas' official product page for the HZU5CLLTRF-E.
What is the maximum power dissipation of the HZU5CLLTRF-E at 70°C ambient?
Per the derating curve in Figure 3 of the REJ03G1216-0500 datasheet, the HZU5CLLTRF-E's maximum power dissipation decreases linearly from 150 mW at 25°C to approximately 105 mW at 70°C ambient. This corresponds to a derating factor of 1.5 mW/°C above 25°C. Exceeding this limit risks exceeding the 150°C junction temperature rating and permanent degradation of the HZU5CLLTRF-E's Zener characteristics.
