Product details
Overview
HZU5BLL-JTRF from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, featuring a nominal Zener voltage of 5.1 V (B grade), 200 mW power dissipation, and ultra-small URP (SC-76A) surface-mount package. It operates with 5 mA test current, exhibits 130 Ω dynamic resistance, and supports stable regulation in battery-powered sensors and microcontroller voltage reference rails.
For engineers reviewing the HZU5BLL-JTRF datasheet, HZU5BLL-JTRF pinout, HZU5BLL-JTRF application, or HZU5BLL-JTRF equivalent, key selection criteria include its ±3% Zener voltage tolerance (5.14–5.37 V), cathode-anode polarity marking, thermal derating behavior above 25°C, and compatibility with reflow-soldered PCB layouts requiring minimal board area.
Technical Context
This Zener diode uses a silicon planar junction structure optimized for stable reverse-biased operation at low currents (IZ = 5 mA). Its design targets tight voltage regulation under ambient temperatures from –55°C to +150°C, with junction temperature limited to 150°C and storage range matching industrial requirements.
The device is characterized by a negative temperature coefficient near 5.1 V (≈ –0.02 %/°C per Fig.2), enabling predictable drift compensation in reference designs. It is tested using 40 ms pulse conditions to avoid self-heating artifacts, ensuring specified VZ, rd, and IR values reflect true small-signal behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5231B-TP (Micro Commercial Co.) | Same 5.1 V nominal, but ±5% tolerance (4.85–5.35 V); 500 mW Pd; SOD-123 package (2.7 × 1.6 mm) | Larger footprint and looser tolerance; better suited for non-critical power rail clamping | Select when higher power margin is needed and board area is not constrained. |
| BZX84-C5V1 (Nexperia) | 5.1 V nominal, ±5% tolerance; 300 mW Pd; SOT-23 package (3.0 × 1.4 mm); 90 Ω rd | Lower dynamic resistance but larger size and wider VZ spread; requires different land pattern | Choose for improved regulation performance where SOT-23 placement is acceptable. |
Compared with MMSZ5231B-TP and BZX84-C5V1, the HZU5BLL-JTRF offers tighter voltage tolerance and smallest footprint-critical for miniaturized reference designs-but requires careful thermal management due to its 200 mW limit and URP package thermal resistance.

FAQ
What is the exact Zener voltage range for HZU5BLL-JTRF at 5 mA test current?
The HZU5BLL-JTRF has a guaranteed Zener voltage range of 5.14 V to 5.37 V when measured at IZ = 5 mA and Ta = 25°C. This B-grade specification reflects ±3% tolerance around the nominal 5.1 V value and is verified per Renesas preliminary datasheet R07DS0423EJ1000 Rev.10.00, Page 2.
Does HZU5BLL-JTRF support reflow soldering, and what is its maximum junction temperature?
Yes, HZU5BLL-JTRF is qualified for standard Pb-free reflow soldering profiles and features an absolute maximum junction temperature (Tj) of 150°C. Its URP package is rated for industrial temperature operation, with storage range from –55°C to +150°C, making it suitable for automated assembly and harsh-environment deployment.
How does the dynamic resistance of HZU5BLL-JTRF affect its performance in a voltage reference circuit?
The HZU5BLL-JTRF specifies a maximum dynamic resistance (rd) of 130 Ω at IZ = 5 mA. This value directly impacts load regulation: for every 1 mA change in shunt current, output voltage shifts by up to 130 mV. In precision reference designs, this necessitates stable bias current and low-noise filtering to maintain sub-1% accuracy.
What is the package type and physical size of HZU5BLL-JTRF?
HZU5BLL-JTRF uses the Ultra-small Resin Package (URP), also known as SC-76A per JEITA, with dimensions of 1.5 mm (L) × 0.8 mm (W) × 0.45 mm (H). It features two terminals-cathode (marked) and anode-and is supplied in TRF taping format (3,000 units per reel) for SMT placement.
Can HZU5BLL-JTRF replace a 5.1 V Zener diode with looser tolerance in an existing design?
Yes, HZU5BLL-JTRF can replace broader-tolerance 5.1 V Zeners (e.g., ±5%) in most cases, provided the PCB land pattern matches the URP (SC-76A) footprint and thermal dissipation remains within 200 mW. Its tighter ±3% grading improves reference stability but may require verification of downstream circuit headroom due to higher minimum VZ (5.14 V).
