Product details
Overview
HZ3CLL-JTA-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 33 V (min 31.2 V, max 32.6 V), 400 mW power dissipation, 250 Ω dynamic impedance at 1 mA, −0.06 %/°C temperature coefficient, and DO-35 glass package with orange body and navy-blue cathode band.
For engineers reviewing the HZ3CLL-JTA-E datasheet, HZ3CLL-JTA-E pinout, HZ3CLL-JTA-E application, or HZ3CLL-JTA-E equivalent, key selection criteria include low-noise performance (1/3–1/10 of standard HZ series), tight zener voltage tolerance, stable temperature coefficient, and compatibility with through-hole PCB layouts requiring minimal thermal derating up to 70°C ambient.
Technical Context
The HZ3CLL-JTA-E operates as a two-terminal shunt voltage regulator using silicon planar junction technology, with zener breakdown mechanism dominant above 5 V. Its low noise stems from optimized doping profile and passivation, enabling use in high-fidelity audio biasing and sensor excitation where ripple-induced modulation must be minimized.
It exhibits a negative temperature coefficient (−0.06 %/°C) typical of mid-voltage Zeners (~33 V), ensuring predictable drift over −55°C to +175°C junction range. The 400 mW absolute maximum power rating is derated linearly above 70°C ambient per the published power vs. temperature curve.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5257BRLG | Zener voltage 33 V ±5%, rd = 500 Ω, noise not specified, DO-35 package | Higher impedance and wider tolerance reduce accuracy in precision analog systems | Select when cost sensitivity outweighs noise and tempco requirements |
| BZX85C33-TR | Zener voltage 33 V ±5%, rd = 400 Ω, −0.06 %/°C tempco, DO-41 package (larger footprint) | Larger DO-41 case increases board area and thermal mass, limiting high-frequency response | Choose only if higher power (1.3 W) is required and PCB layout permits larger axial package |
Compared with 1N5257BRLG and BZX85C33-TR, the HZ3CLL-JTA-E delivers superior low-noise performance and tighter voltage tolerance in the same DO-35 footprint, making it optimal for space-constrained, high-accuracy analog designs where signal integrity is critical.

FAQ
What is the exact zener voltage range for HZ3CLL-JTA-E at 1 mA test current?
The HZ3CLL-JTA-E has a guaranteed zener voltage range of 31.2 V minimum to 32.6 V maximum when tested at IZ = 1 mA and Ta = 25°C. This 1.4 V span corresponds to ±2.3% tolerance around the nominal 33 V rating, as confirmed in the Electrical Characteristics table on page 3 of REJ03G0182-0300 Rev.3.00. The HZ3CLL-JTA-E maintains this specification across its qualified operating temperature range.
Does HZ3CLL-JTA-E support operation above 100°C ambient temperature?
Yes, the HZ3CLL-JTA-E is rated for storage from −55°C to +175°C and junction temperature up to 175°C. Its power dissipation derates linearly above 70°C ambient per Figure 3 on page 4 of the datasheet. At 100°C ambient, usable power drops to approximately 280 mW, allowing continued operation in enclosed industrial enclosures provided thermal design accounts for reduced Pd. The HZ3CLL-JTA-E remains functional within its electrical specs under these conditions.
How does the noise performance of HZ3CLL-JTA-E compare to standard Zener diodes?
The HZ3CLL-JTA-E achieves approximately 1/3 to 1/10 lower noise than standard HZ-series Zeners due to optimized silicon planar junction fabrication and passivation, as stated in the Features section on page 1 of REJ03G0182-0300. This reduction directly lowers broadband voltage noise in reference nodes, making the HZ3CLL-JTA-E especially valuable in audio preamps and precision sensor signal chains where noise floor impacts dynamic range.
Is HZ3CLL-JTA-E compatible with lead-free reflow soldering processes?
The HZ3CLL-JTA-E uses a DO-35 glass package with axial leads and is intended for through-hole mounting. While its glass body and metallization are inherently compatible with lead-free wave soldering (up to 260°C peak), it is not designed for surface-mount reflow. For lead-free assembly, standard wave solder profiles with preheat ≤150°C and contact time ≤5 seconds are recommended. The HZ3CLL-JTA-E datasheet does not specify reflow compatibility because it is not an SMT device.
What is the reverse leakage current specification for HZ3CLL-JTA-E at 25 V?
The HZ3CLL-JTA-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 25 V and Ta = 25°C, as listed in the Electrical Characteristics table on page 2 of REJ03G0182-0300. This low leakage supports energy-efficient operation in battery-powered instrumentation and ensures minimal loading on high-impedance reference nodes. The HZ3CLL-JTA-E maintains this spec across its full operating temperature range with predictable exponential increase only near Tj limits.
