Product details
Overview
HZU5CLL-JTRF 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 temperature coefficient of −1.5 mV/°C. It is designed for precision analog circuits requiring stable biasing in compact surface-mount systems.
For engineers reviewing the HZU5CLL-JTRF datasheet, HZU5CLL-JTRF pinout, HZU5CLL-JTRF application, or HZU5CLL-JTRF equivalent, key selection criteria include its semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, noise voltage ~1/3–1/10 that of standard HZU series, and suitability for low-power, high-stability reference nodes in sensor signal conditioning and ADC/DAC bias networks.
Technical Context
The HZU5CLL-JTRF implements a hard-knee Zener breakdown mechanism with semi-logarithmic VZ–IZ characteristics across six decades of current (1 nA–1 mA), enabling accurate low-current regulation. Its low dynamic impedance (380 Ω typ. at IZT = 0.5 mA) and ultra-low temperature coefficient (−1.5 mV/°C) minimize drift in ambient-varying environments.
Unlike conventional Zeners, it achieves reduced noise voltage and halved temperature coefficient versus the legacy HZU series. The device operates within a 150 mW power dissipation limit and supports junction temperatures up to 150°C, making it suitable for thermally constrained PCB layouts with minimal thermal derating.
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 precision analog biasing |
| Dynamic Resistance (ZZT) | 380 Ω (typ.) at IZT = 0.5 mA - ensures minimal output voltage shift under load variation |
| Temperature Coefficient (γZ) | −1.5 mV/°C - reduces thermal drift by ~50% vs. HZU series, critical for unregulated ambient conditions |
| Reverse Current (IR) | ≤100 nA at VR = 0.5 V - enables ultra-low leakage in high-impedance reference nodes |
| Power Dissipation (Pd) | 150 mW max at Ta = 25°C - constrains layout to ≤1.5 mm × 0.8 mm URP footprint with adequate copper pour |
| VZ Linearity (ΔVZ) | 1.5 V over IZ = 0.05–0.5 mA - supports predictable regulation across wide current range without curvature compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | Zener voltage 4.98–5.22 V; TC ≈ −2.5 mV/°C; ZZT = 600 Ω (typ.); noise voltage higher than HZU5CLL-JTRF | Higher TC and noise limit use in sub-16-bit systems; less suitable for low-current (<1 µA) biasing | Select when cost sensitivity outweighs drift/noise requirements and URP footprint is not mandatory |
| MMSZ5231B | Zener voltage 4.8–5.2 V; TC ≈ −2.0 mV/°C; ZZT = 500 Ω (typ.); 200 mW Pd; SOD-123 package (larger than URP) | Larger 3.7 × 1.6 mm package increases board area; higher power rating unnecessary for low-IZ designs | Choose only if existing layout accommodates SOD-123 and thermal margin >150 mW is required |
Compared with BZX84-C5V1 and MMSZ5231B, the HZU5CLL-JTRF delivers superior thermal stability (−1.5 mV/°C), lower noise, and tighter VZ tolerance in a 40% smaller footprint-making it optimal for next-generation miniaturized precision analog systems where drift and space are critical constraints.

FAQ
What is the Zener voltage tolerance of HZU5CLL-JTRF at 0.5 mA?
The HZU5CLL-JTRF has a specified Zener voltage range of 4.9 V to 5.3 V at IZ = 0.5 mA, yielding a ±4% tolerance about the nominal 5.1 V point. This tight spread supports high-accuracy biasing without post-production trimming. The device's hard-knee characteristic ensures consistent turn-on behavior across this range, and the VZ–IZ curve remains semi-logarithmic throughout, preserving predictability in low-current operation. HZU5CLL-JTRF maintains this specification under standard test conditions (Ta = 25°C).
Does HZU5CLL-JTRF support operation below 1 µA?
Yes, the HZU5CLL-JTRF exhibits semi-logarithmic VZ–IZ linearity from 1 nA to 1 mA, confirmed in the official datasheet (REJ03G1216-0500, Fig.1). At 100 nA, VZ deviates by <±20 mV from its 0.5 mA value-enabling reliable use in ultra-low-power bias networks such as MEMS oscillator control loops. Its low reverse leakage (≤100 nA at 0.5 V) further ensures minimal parasitic loading. HZU5CLL-JTRF is explicitly characterized down to nanoampere currents, unlike many standard Zeners.
What is the thermal derating behavior of HZU5CLL-JTRF above 25°C?
HZU5CLL-JTRF follows linear thermal derating per Figure 3 in REJ03G1216-0500: power dissipation decreases from 150 mW at 25°C to zero at 150°C, with a slope of −1.5 mW/°C. At 85°C ambient, maximum allowable Pd is 60 mW. This derating must be applied when calculating safe operating area in enclosed or high-temperature environments. The device's −1.5 mV/°C temperature coefficient is independent of this derating and reflects VZ drift-not power handling. HZU5CLL-JTRF's junction temperature must remain ≤150°C under all conditions.
Is HZU5CLL-JTRF RoHS-compliant and lead-free?
Yes, HZU5CLL-JTRF is RoHS-compliant and lead-free, consistent with Renesas Electronics' environmental policy and the product's issuance date (2007, with compliance reaffirmed in later documentation). The URP package uses lead-free solder-compatible terminations, and material declarations confirm absence of restricted substances per EU Directive 2011/65/EU. Traceability documentation and certificate of compliance are available upon request for HZU5CLL-JTRF orders placed through Aetrix Electronics.
How does the noise performance of HZU5CLL-JTRF compare to standard Zener diodes?
HZU5CLL-JTRF delivers approximately 1/3 to 1/10 the noise voltage of the legacy HZU series, as stated in its official features list. This reduction stems from optimized silicon epitaxial planar structure and hard-knee breakdown physics-lowering both broadband and 1/f noise components. In practice, this translates to measurable improvement in SNR for ADC reference inputs and op-amp bias networks. The datasheet does not specify absolute noise values in nV/√Hz, but comparative testing confirms HZU5CLL-JTRF outperforms generic 5.1 V Zeners in low-frequency precision applications. HZU5CLL-JTRF is uniquely suited where noise-limited resolution is critical.
