Product details
Overview
HZ5CLL-J-E from Renesas is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.7 V (min 5.7 V / max 6.0 V), 400 mW power dissipation, 80 Ω dynamic impedance at 0.5 mA test current, and DO-35 glass package with orange body and navy blue cathode band. It serves in stabilized power supplies, reference voltage sources, and noise-sensitive instrumentation.
For engineers reviewing the HZ5CLL-J-E datasheet, HZ5CLL-J-E pinout, HZ5CLL-J-E application, or HZ5CLL-J-E equivalent, key selection criteria include its low-noise performance (≈1/3–1/10 of standard HZ series), tight zener voltage tolerance, low leakage, and thermal stability across −55°C to +175°C operating range.
Technical Context
The HZ5CLL-J-E operates as a two-terminal voltage reference device using silicon planar junction technology optimized for reduced flicker and thermal noise. Its zener voltage is specified at 0.5 mA test current with DC excitation, and it exhibits a temperature coefficient of approximately −0.04 %/°C near 5.7 V.
Designed for low-current regulation, it maintains stable breakdown behavior under reverse bias with maximum junction temperature of 175°C and storage range spanning −55°C to +175°C. The device's 80 Ω dynamic resistance ensures minimal output voltage variation under load changes typical in sensor biasing and ADC reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.7 V min / 6.0 V max at IZ = 0.5 mA - defines precise regulation point for low-drift references |

|---|---|---|
| 1 (Cathode) | High-side terminal under reverse bias | Connected to regulated positive rail; polarity marking critical for correct orientation in series-shunt regulation |
| 2 (Anode) | Low-side terminal under reverse bias | Typically grounded or connected to lower potential node; completes current path during zener conduction |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C5V6 (ON Semiconductor) | 5.6 V nominal, ±5% tolerance, 600 mW Pd, 40 Ω rd, DO-35 package | Higher power but higher noise and looser VZ tolerance; lacks documented low-noise optimization | Select when higher power handling is prioritized over noise floor and tighter regulation. |
| MMSZ5232B (Diodes Inc.) | 5.6 V nominal, ±5% tolerance, 500 mW Pd, 17 Ω rd, SOD-123 surface-mount | Lower dynamic impedance but SMT-only; no low-noise characterization; different thermal profile | Choose for space-constrained PCBs where board area outweighs noise sensitivity and through-hole assembly is unavailable. |
Compared with BZX55C5V6 and MMSZ5232B, the HZ5CLL-J-E delivers superior noise performance and tighter voltage tolerance in a proven through-hole DO-35 package, making it optimal for legacy-reliant, high-fidelity analog systems where long-term stability and low drift are design-critical.

FAQ
What is the exact zener voltage range for HZ5CLL-J-E?
The HZ5CLL-J-E has a guaranteed zener voltage range of 5.7 V minimum to 6.0 V maximum when tested at 0.5 mA DC current, per Renesas document REJ03G0182-0300 Rev.3.00. This 300 mV span reflects the "B2" variant designation within the HZ-L family and ensures consistent regulation in precision analog designs where tight voltage tolerance is required.
Is HZ5CLL-J-E compatible with lead-free soldering processes?
Yes, the HZ5CLL-J-E in DO-35 glass package is rated for standard lead-free reflow profiles with peak temperatures up to 260°C, consistent with JEDEC J-STD-020. Its glass encapsulation and axial leads tolerate thermal cycling without delamination or parameter shift, and Renesas confirms compatibility in application note AN-1009 for HZ-L series assembly.
Does HZ5CLL-J-E have a specified noise spectral density?
No, the HZ5CLL-J-E datasheet does not provide quantitative noise spectral density (nV/√Hz) values. Instead, Renesas specifies comparative noise performance: "approximately 1/3–1/10 lower than the HZ series," verified via broadband noise measurements in the referenced application circuit on page 1 of REJ03G0182-0300. For absolute noise modeling, empirical bench validation is recommended.
What is the maximum allowable reverse current for HZ5CLL-J-E before degradation?
The HZ5CLL-J-E is rated for continuous operation at up to 0.5 mA zener test current, with absolute maximum power dissipation limited to 400 mW. Exceeding 0.5 mA significantly increases self-heating and accelerates long-term parameter drift; sustained operation above 1 mA risks irreversible junction degradation. Derating per Figure 3 (page 4) is mandatory above 50°C ambient.
Can HZ5CLL-J-E be used in series or parallel configurations?
Series connection of HZ5CLL-J-E units is not recommended due to mismatched zener voltages and temperature coefficients causing current hogging. Parallel use is also discouraged unless actively balanced, as minor VZ variations (±0.15 V) lead to unequal current sharing and thermal runaway. For higher voltage or current, select a single higher-rated device or dedicated IC reference.
